The Zhengzhou Lijia 48-filter cartridge dust collector is a high-performance dust removal equipment, playing an outstanding role in the field of industrial dust control. It adopts a pulse-jet ash cleaning method, which ensures remarkable ash cleaning effect and stable operation of the equipment. The whole machine integrates a fan, single-chamber dust collector, and ash cleaning mechanism, featuring a compact structure and strong adaptability, making it flexibly deployable in various places such as crushing, conveying, lifting, batching, silo tops, silo bottoms, and cement bulk loading. For flammable and explosive dust, anti-combustion and anti-explosion measures can be added while adjusting the body structure. The filter bag material can be selected from different types of needle felt according to the dust characteristics, with an average service life of more than two to three years. The upper end of the filter bag is designed without a venturi tube, only equipped with a blowpipe, which reduces the working resistance and makes maintenance and repair more convenient. The electromagnetic pulse valve is of 1-inch specification, with each blowpipe corresponding to one valve. Some products use Shanghai bag-type right-angle pulse valves with a double-diaphragm structure, which are sensitive in control, efficient, and long-lasting. With these advantages, the Zhengzhou Lijia 48-filter cartridge dust collector has been widely applied and rapidly promoted in industries such as cement, electricity, metallurgy, and chemical engineering.

To trap and purify the floating dust generated during the spray booth's operation, and to facilitate the rapid dissipation of spraying heat, the spray booth is outfitted with a ventilation and dust removal system.
Determination of ventilation volume
Based on the volume of the soundproof room, according to different uses, the air volume is calculated according to the number of air changes of 50~150 times/h, which has been verified by practical use
The ventilation volume is optimal.
Cloth method
Referring to the American design and combined with our company's experience in ventilation and dust removal of similar soundproof rooms, it is recommended to use longitudinal airflow for the whole room and air intake
The mouth is opened on the roof and an arc-shaped uniform flow dispersion network is set up to eliminate the concentration of air intake and the dead angle of ventilation, so that the air flow can enter the room evenly.
Suction bellows
Designed as a wide-mouth type, a bucket suction box is set under the spraying area to generate negative pressure to quickly absorb dust in the room.
Then the circular air duct is used to transmit the air flow to the dust collector;
Ventilation mufflers
In the air outlet of the soundproof room, a silencer with a length of more than 1 meter is used with a sound-absorbing structure to make noise along the air duct to the spraying room When propagating outside, the noise of the air duct is further reduced.
Ventilation mufflers
Cartridge dust collector
The dust collector is made according to the original drawings provided by the American company, the outer wall board is smooth and beautiful, the filter cartridge is made of Donaldson-style wood pulp fiber combined with polyester fiber nano flame retardant film, and the filtration accuracy is 5μm ,
For the spraying powder dust removal efficiency of 99.9%, the shape of Ø350*660mm, the area of a single filter cartridge filter unit is 21m2, the recommended filtration speed is 0.4~0.8m/min, the form of ash cleaning is electric pulse blowing, automatic control, the dust collector is equipped with an ash storage box with wheels, and the fixing method is buckle type, which is very convenient for loading and unloading, which is conducive to user recovery and ash cleaning.
Dust collector filters
Features of the dust collector filter element:
Induced draft fan
The fan is the kinetic energy core of the airflow, and its flow, full pressure, power, and model are all selected and set up to meet the needs of ventilation and dust removal. We have long-term fan with stable quality. The noise of the fan is also a noise source during operation, if the customer has strict requirements for the noise of the factory, the customer buys the fan sound insulation room, the design sound insulation of the fan sound insulation room is ≥ 20dB (A), after noise reduction, the noise is less than 70 decibels, and the noise emitted is the same as the spraying sound insulation room, and the appearance is also beautiful; If the customer does not have strict requirements for noise at the plant boundary, there is no need to install a fan soundproof room;
Centrifugal fan
Exhaust pipes
Most of the exhaust cylinders are set up outdoors and in the open air, and the rain cap is installed at the top, and the air flow rate in the exhaust cylinder is controlled at a low of 10m/s
left and right to prevent the regeneration of airflow noise and affect the surrounding area.

Product Operate Guide
1. Equipment status verification: check whether the filter element is installed firmly before starting, the pulse cleaning pipeline is not loose, and the explosion-proof venting membrane is not damaged; Confirm that the power supply connection of the electric control cabinet is stable, the PLC display screen shows the "standby" status, and the communication with the spraying room control system is normal.
2. Environment and material cleaning: empty the residual dust of the ash hopper and check that there is no debris blockage at the air inlet; Confirm whether a suitable wear-resistant lining or anti-stick coating has been installed depending on the spraying material.
3. Process parameter preset: input the size of the spraying room and the estimated dust concentration through the operation interface, and the system will automatically match the fan frequency and ash cleaning cycle; In high-temperature spraying scenarios, the air-cooled pre-cooling module needs to be turned on in advance, and the inlet air temperature threshold should be set below 120°C.
