32 Cartridges Baghouse Industrial Dust Collector For Thermal Spray

32 Filter element pulse ventilation dust removal system

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.

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.

1.Mechanical Processing Industry: During the cutting, grinding, polishing and other processing procedures of mechanical parts, a large amount of metal dust will be generated. The thermal spray dust collector can effectively collect this dust, ensuring a clean workshop environment and protecting the health of workers. Meanwhile, it can avoid the abrasion and impact of dust on processing equipment, improving processing precision and the service life of the equipment.

2.Automobile Manufacturing Industry: In the automobile production process, procedures such as welding, painting, and component processing will generate a variety of dust and harmful gases. The thermal spray dust collector is capable of efficiently treating different types of pollutants, ensuring that the production environment complies with environmental protection requirements and enhancing the quality of automobile products.

3.Aerospace Field: This field has extremely high requirements for the processing precision and environment of components. The thermal spray dust collector can precisely control the dust concentration, providing a clean and stable production environment for the manufacturing of aerospace components and guaranteeing product quality and performance.

4.Metal Surface Treatment Industry: Processes such as thermal spraying, electroplating, and sandblasting will generate a large amount of metal dust and harmful gases. The thermal spray dust collector can effectively remove these pollutants, reducing environmental pollution.

5.Powder Metallurgy Industry: In the powder metallurgy production process, dust is likely to fly during the transportation, mixing, pressing and other links of powders. The thermal spray dust collector can collect dust in a timely manner, preventing the occurrence of safety accidents such as dust explosions and ensuring the safety and stability of the production process.

6.Electronic and Electrical Appliance Industry: The production of electronic components has strict requirements for environmental cleanliness. The thermal spray dust collector can remove the dust generated during the production process, preventing dust from contaminating and damaging electronic components and improving the yield rate and reliability of products.

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.
