Micron-sized dry fog dust suppression system

Abstract

The invention discloses a micron-sized dry fog dust suppression system. The system comprises a water supply module and an air supply module, the output ends of the water supply module and the air supply module are both communicated with a water-air distributor, the output end of the water-air tube of the water-air distributor is connected with a dry fog machine, the dry fog machine is communicatedwith a plurality of sub-control boxes through connecting tubes, and the sub-control boxes are communicated with dry fog spray heads through connecting tubes; and the sub-control boxes are electrically connected with a laser dust sensor, the plurality of sub-control boxes are electrically connected with a PLC, and the PLC is connected with the water-air distributor through a wire. The dust suppression system can monitor dusts on a processing assembly line in real time through the laser dust sensor arranged in a specific area, and when the dust concentration is too high, a model is transmittedto the PLC, the PLC controls the water-air distributor to increase the water-air output, and the sub-control boxes are turned on to make a large amount of dry fog nozzles at the corresponding positions to participate in dust suppression work, so that the system has high applicability, avoids the wastes of water-air resources, and has a good dust suppression effect.

Description

technical field [0001] The invention belongs to the technical field of dust suppression equipment, and in particular relates to a micron-level dry fog dust suppression system. Background technique [0002] The principle of micron-level dry fog dust suppression is based on the research results of European and American scientists, that is, "the probability of adsorption, filtration, and condensation of water mist particles and dust particles is the largest." When the airflow containing dust particles bypasses the droplets, the probability of the droplets catching the dust particles in the airflow is related to the diameter of the droplets. When the fog droplets are large, the dust particles are simply bypassed by the airflow without being captured. When the size of the mist and dust particles is similar, it is easier to collide and catch the dust particles. Micron-scale dry fog uses this principle to generate fog droplets below 5 μm, which are similar in size to ultrafine du...

Problems solved by technology

[0003] The micron-level dry fog dust suppression system currently in use is equipped with micron-level dry fog nozzles at specific positions on the processing line to continuously output dry fog for dust reduction. It is impossible to regulate the output of dry fog according to the actual dust concentration, which is likely to cause In the case of excessive dry fog concentration or insufficient dust suppression effect in a certain area, it is necessary to improve the design in a targeted manner
