Jiangsu workshop welding fume purification device which is more cost-effective
Working principle of welding fume purifier
The work produced by the dust suction hood suction smoke purifier, first through the first layer of fire purifier, separation of particles can be produced on the Mars interception large granular and polished, preliminary filtered air enters into the second layer filter protective plate, the protective plate to prevent the residual shunt and Mars directly to the main filter; the separated dust gas into the third storey main filter for the ultimate purification, the main filtering effect of the filter element is as high as 99.9%, due to the high efficiency of filtering accuracy of the main filter can reach indoor emission standards, the filtered clean air directly into the indoor air outlet is circulated through the purifier. 2 mobile welding smoke purifier configuration two suction arm, the bottom is equipped with 2 directional, 2 universal casters with polyurethane brake device, used for welding mobile station. The suction arm can be 360 degrees of freedom rotation stops, by pulling the hood on the handle, can be flexible with the intention of the operator to position and dust suction angle, and in the absence of external force to the air; the optional 2m, 3M flexible suction arm; suction hose with high temperature resistant, flame retardant, wear resistant composite real the material, not because Mars wear after cracking, longer service life; for the 160mm. arm tube diameter
Requirements and cleaning methods of dust filter cartridge
Dust filter cartridge usually it must meet the following requirements. The lack of sufficient volume, usually require storage hopper volume 8~16, the amount of ash. In order to protect the ash handling system, it plays an important role in temporary storage. To ensure smooth ash discharge bucket, bucket rest angle is larger than 60. And the rest angle is the angle between the horizontal plane of the ash hopper slope 1. At the intersection between an inner wall two hopper wall should be installed arc plate, to prevent dust filter dust here. In order to prevent an internal temperature and fouling, an outer wall surface is provided with a heating device. A device for heating the hopper usually has two kinds, one is the steam heating; an electric heating mode.
Automatic cleaning mode of dust filter commonly used high-pressure gas pulse cleaning, mechanical vibration. Pulse blow to the solenoid valve is a signal control device using parameter preset, instant opening and closing the electromagnetic valve diaphragm, the high-pressure gas into the gas injection pipe, with the rapid expansion of the surface of the filter cylinder dust shake force. The general gas pressure we set for 6 kg. Mechanical vibration cleaning used in small single cartridge dust collector, it is powered by a shaking dust collector in the eccentric device cleaning, the filter cartridge filter action requires operation after shutdown.
Welding fume purifier note:
　　
1): this series of products can only be used for welding fume purification. If the humidity is too large, will cause the dust hardening of the filter tube wall, thereby affecting the purification efficiency of the purifier;
2): clean up the dust on the filter regularly to keep the air flowing smoothly;
3): clean up the dust in the suction arm regularly to keep the air flowing;
4: regular maintenance of the fan, to extend the service life;
5: pay attention to the loss of the filter at any time, timely replacement of filter fiber;
6): timely replacement of the seal used to prevent the aging of the seal and the impact of work;
7): clean the dust in the dust collecting drawer in time to avoid the dust accumulation.
The role of welding smoke purifier
Welding smoke cleaning machine is designed for industrial welding fume and light particles and the design of the cleaning device, which is light and flexible, easy to operate, it is widely used in chemical industry, electronics, metal processing, tobacco, glass, pharmaceutical, food processing, cleaning room, hospital and other industries such as dust, smoke pollution place.
The metal will produce a variety of toxic and harmful gases or other industrial welding process, welding machine welding smoke smoke purifying exhaust gas purification machine, properties and processing characteristics of smoke gas, we will through the experiment, in the guarantee will not produce does not affect the car operation among two pollution, does not affect the service life of the equipment under the premise. Multistage purification device for welding smoke exhaust gas purification treatment, which can effectively remove the welding smoke and waste gas, and can degrade the welding smoke smell of tar and various toxic and harmful gases.
Its working principle is as follows: welding smoke and waste gas by the blower suction purification machine, large dust particles are plate and at the beginning of the filter and deposited into the micro level; purifying device for smoke and exhaust through the exhaust device is filtered and discharged after standard gas decomposition.
The exhaust gas is first decomposed by a liquid absorption device, and then the gas enters the active carbon adsorption layer after the high efficiency filter. Activated carbon adsorption unit adsorption, and finally through the purification of the membrane gas discharge standards
