With the progress of the air filtration industry, many types of air filters have been derived. Among them, the air duct type automatic rolling curtain filter is the more outstanding one, and the application range is also the most widely used type, so its market is also The biggest one, all users will give praise after use, why is this the case? Because it has very unique advantages, such as the following aspects:

First, what has to be said is the efficiency of dust removal and filtration of the roller blind filter. The use of a wind pipe type automatic winding filter can filter the coarse particles with a content of more than 85% in the air at one time, so that the air at the air outlet can be filtered. The quality is excellent and reliable, which greatly reduces the frequency of replacement of the rear filter, and is a reliable operation for the safe and effective operation of the entire air treatment system.

Second, the unique design of the air duct type automatic roller shutter filter, seamlessly connected with the air inlet pipe, eliminates the need for environmental protection engineers to consider the installation of the roller shutter filter on site, and the goods can pass through the interface flange after reaching the site It is directly sealed with the pipelines and equipment on site, which is convenient and quick, and its installation efficiency is also staggering.

Third, the patented filter material quick change function of the air duct type automatic rolling screen filter , enters the inside of the pipeline when customer maintenance is not required, and only needs to complete a series of maintenance work such as overall equipment debugging and filter material replacement outside the box. The design that does not need to enter the pipeline is currently favored by customers in various air treatment projects such as chemical industry, painting, VOC gas filtration, RTO regenerative incinerator, etc. With the current domestic emission standards becoming stricter and more standardized, our roller shutter filter series products have been sought after by environmental protection engineering companies.

Fourth, the air duct type automatic rolling curtain filter is energy-saving and environmentally friendly. The data shows that under normal working conditions, its working rated power is only 100w-200W. Under daily standby conditions, there is almost no power consumption. When the material reaches the value of the replacement pressure difference, the power consumption of the starter motor product will last only a few minutes. This shows that its later power operation cost is quite low.

Fifth, the new super-wide and super-wide new filter material storage device of the air duct type automatic rolling screen filter can store the filter material used by customers for 5-15 times. Greatly save the cost of manpower operation in the later stage. Nowadays, as labor costs continue to rise, this innovative filter type has been recognized by customers with large ventilation areas.

Sixth, the air duct type automatic rolling curtain filter provides the possibility of online replacement. As we all know, for some chemical and coating production lines, the cost of downtime for maintenance of the entire system is quite huge. The introduction of the duct type roller shutter filter can be said to solve the problem of online replacement.

These advantages are only more obvious. Specifically, the air duct type automatic rolling shutter filter has many advantages, because in this case, it is not an article that can be described one by one, but only these Advantages are enough to satisfy users and make them feel worthwhile, don’t you think?

Automatic roller blind air filter

Project Name: Huaifang Reclaimed Water Plant Project Water Area Process System and Equipment Air Roller Blind Filter

Project introduction: Roller curtain air filter products are applied to the fresh air filtration at the front end of the blower of the water area process system

Undertaking time: 2016.1

Huaifang Reclaimed Water Plant is the first all-underground reclaimed water plant in Beijing, and it is also the largest reclaimed water plant project in Asia where the main treatment process is all underground. After completion, the Huaifang Reclaimed Water Plant can generate 200 million yuan in full capacity operation throughout the year. Cubic meters of sewage are converted into usable reclaimed water, which is equivalent to 100 Kunming Lakes, which can be called Beijing’s “underground water city”.
The Huaifang Water Reclamation Plant project is located in the southwestern part of Beijing, adjacent to Majiapu West Road and Huaifang Road, with Nanhuan Railway on the north side and Tongjiu Road on the south side. The planned watershed starts from the eight major places of Xishan in the west, Zhanguan Road in the east, Changhe in the north, and Fengtai in the south, including some rural areas in Huaxiang, Lugouqiao Township, and Shijingshan Township. The drainage area is about 137 square kilometers.
“The longest length of the reclaimed water plant project is 805 meters from east to west, and the widest point from north to south is 519 meters. It includes 45 buildings and structures. The underground part covers an area of 162,200 square meters, with two underground floors and three underground floors in part (pipe corridors). The ground landscape of the water plant will build a Huaifang Wetland Reserve.” said Liu Kuisheng, the project manager of the Huaifang Reclaimed Water Plant. The processing scale of the water plant is 600,000 cubic meters per day. The reclaimed water treatment system adopts the world’s advanced technology, and the effluent quality reaches the national surface water. Environmental IV standards. At the same time, the sludge treatment process of thermal hydrolysis + digestion + plate and frame dehydration is also used in the plant area to realize the harmless disposal of sludge.
On the roof of the water plant, there are 8 layers of protective and waterproof layers totaling 17 cm thick. At present, the roof full water test is in progress. According to the current test results, there is no problem in building a wetland landscape on the roof.

Where will the sewage treatment be used after it becomes clear?
Mainly supplying industrial and commercial water, above-ground wetland parks, etc. At the construction site of the Huaifang Reclaimed Water Plant, there are four huge biological ponds. Liu Kuisheng said that the sewage from the west of Beijing will be absorbed here, and after treatment, the usable clean reclaimed water will be discharged. Entering the water plant from an external pipeline, there are manual, automatic and manual plus automatic three gates, as well as an automatic control system to prevent flooding. Only sewage not exceeding 600,000 cubic meters per day is allowed to enter the water plant.”
According to the design requirements, there are three pipelines connected to the water plant. The treated reclaimed water mainly supplies industrial and commercial water, the above-ground wetland park and returns to the Xiaolong River, including serving the Lize Business District.

How to remove impurities and bacteria in sewage?
Ultrafiltration membrane technology for screening, ozone and ultraviolet double disinfection. The world-advanced ultrafiltration membrane technology developed by Beijing Drainage Group is the key to clean sewage.
“This kind of membrane is made up of one-thousandth of a hair thin. The 1280 sets of membrane modules are like 1280’sieves’, allowing only molecules below 20 nanometers to pass through, so as to screen out various bacteria and viruses.” Liu Kuisheng said. .
Coarse grille removes debris more than 3 cm, rotary grille removes debris more than 1 cm, fine grille removes debris of 4 mm, aeration grit tank removes debris of 2 mm… each tank, each equipment Remove debris of different sizes. 32 mud scrapers are installed in the primary sedimentation tank, each 65 meters long, the sludge here and the sludge in the back membrane tank will be transported into the mud area for processing.
After removing 0.5 mm of debris from the membrane grid, it enters 4 biological ponds that can hold 600,000 cubic meters of sewage through the pipeline, and then controls the ammonia nitrogen and phosphorus in the sewage in the biological pond to be within the standard of surface IV water. Inside.
“Bacteria, viruses and other harmful substances are larger than 20 nanometers in diameter, and they are basically screened out.” Liu Kuisheng said that the turbid sewage will immediately turn into clean water after this “sieve”, and then it will be double disinfected by the ozone contact pool and the ultraviolet disinfection room. All the indicators reach the surface level IV reclaimed water before entering the clean water pond.

As shown in the figure, the fresh air of the air conditioner in a heavily polluted environment is so dirty, and the filter material fibers of the automatic rolling-blind filter have accumulated thick dust. This batch of automatic winding filters is used in the pre-filtration system of the air-conditioning fresh air unit of the second phase of the BOE Hebei Mobile Display System Project.
