The main body box is made of excellent carbon steel, with air tightness design. The inspection door is made of excellent sealing materials, and kerosene is used for leak detection in the manufacturing process. The air leakage rate is very low. Manhole access door is set at the top to facilitate the installation and replacement of filter materials; The boxes of different specifications can be customized according to the needs. The box is divided into several chambers, separated by partitions, which are airtight to each other and realize off-line ash removal; Each room is equipped with a poppet valve to switch the filtered air flow; The upper box is designed with a certain slope, which is conducive to the smooth drainage of rainwater; The middle box is made of steel plate with thickness of 5mm, and the surface is painted with rust prevention, firmness and durability.

Folded cylindrical, with an outer diameter of 320mm, an inner diameter of 220mm, and a cylinder height of 660mm. The inner and outer parts are supported by metal frames, and the upper and lower parts are fixed by a top cover and a base. The filter area of a standard filter cylinder is 23m2, while the filter area of the same type bag is only 1m2; The arrangement and layout are reasonable, and the horizontal combination is installed, and the upper inlet air and the lower exhaust air are used. This structure is conducive to the introduction of dust containing gas into the filter cartridge carriers in the dust collector room and the uniform distribution. It is also conducive to the falling of the dust that is bounced off in the instant of back blowing and cleaning, and reduces the possibility of secondary adsorption; The lower exhaust structure is directly introduced into the fan through the clean air chamber. The fan motor is floor type, which enhances the stability of the equipment and saves unnecessary waste caused by pipeline connection.

The filter cartridge adopts the new material produced by Donaldson technology. The filter material is 100% polyester fiber with a thickness of 0.80mm; Heat resistant maximum temperature: 80 ℃; Air permeability: 220m ³/ m2/h； Weight: 260g / m2; Filtration precision: 5um-10um;Filtration resistance: ≤ 46pa; Filtration efficiency: ≥ 99.99%

Pulse filter cartridge dust collector air pipe adopts δ 1.5mm galvanized plate undercut fabrication, no welding, anti-corrosion and thermal insulation treatment, compact air duct layout, small air flow resistance, avoid horizontal pipes in pipe design, and minimize elbows; The pipeline is connected by flanges, and asbestos rope is filled between the flanges as the sealing material, which is beautiful and durable.

The double suction bkkf explosion-proof centrifugal fan is adopted for the filter cartridge dust collector, which has the characteristics of good performance, high efficiency, beautiful appearance, compact structure, stable operation, and convenient installation and maintenance. The forced draft fan base is welded into a frame with channel steel and angle steel industrial profiles to bear the weight and vibration of one forced draft fan; Air supply pipes are all made of δ 1.2mm high-quality galvanized steel plate undercut production, without welding, to ensure that the pipeline is formed without deformation; A damping or elastic reducer is installed at the bottom of the fan. At the same time, we have designed a fan noise reduction room to ensure that the system noise is controlled below 75dBA.

The dust remover adopts the pulse back blowing method. Its working principle is: when the pulse controller sends a signal, the exhaust port of the pulse control valve is opened, the gas outside the back pressure of the pulse valve is released, the pressure difference is generated on both sides of the diaphragm, the diaphragm is displaced due to the pressure difference, and the pulse valve is opened. At this time, the compressed air is ejected from the air bag through the pulse valve through the nozzle hole (the gas ejected from the injection pipe is primary air). When the high-speed air flow passes through the venturi inducer, the surrounding air (called the secondary air) which is several times of the primary air enters the filter bag, causing the instantaneous positive pressure in the filter bag to achieve the purpose of ash cleaning.

The dust hopper is conducive to the discharge and collection of dust and the maintenance of the dust collector. The rotary valve can be configured to automatically and continuously transport the dust in the dust hopper to the conveying system or the collection container; Generally, the dust collecting bucket is equipped with two dust collecting bucket trucks, and the quick connection structure is adopted, which is closed and easy to open. The cleaning workers can easily open it and then pull it to the designated position to handle the dust, so that the environment is not polluted by the secondary flying caused by the shipping of other containers.

The single dust remover is controlled by a single machine, and the pulse controller is set as the timed automatic circulation ash cleaning. The combined dust remover is controlled by the pulse controller combination or PLC, and is set as the automatic circulation ash cleaning
