Dust removing and explosion preventing apparatus for wood dust explosion

Abstract

The present invention discloses a dust removing and explosion preventing apparatus for wood dust explosion. According to the present invention, during the process from wood dust transportation to dust removing, an electromagnetic iron removing device, a metal wire, an electric conduction coating material and a metal shell are synergistically used, such that the generation of static electricity is avoided, and the wood dust burning explosion caused by static spark is inhibited; through the synergetic effect of a temperature measurement device and a monitor, the temperature and the pressure during the dust removing process are real-timely monitored; by matching a water sprinkling head and a rapping device, the burning explosion caused by the clogging during the material discharging after the dust removing or the contact of the discharged material and air at the high temperature is avoided; through the synergetic effect of a polytetrafluoroethylene film, an electromagnetic pulse blowing device and a vibration rod, clogging and hardening cannot be caused during the dust removing process, the long-term operation can be achieved, the apparatus has advantages of high-temperature resistance and corrosion resistance, and it can be ensured that the dust collector does not produce the burning explosion after the long-term work at the high temperature; and by matching a fireproof ring and a spraying nozzle, the secondary burning explosion can be prevented, and the burning explosion of the discharged waste gas can be avoided.

Description

technical field [0001] The invention belongs to environmental protection dust removal and explosion-proof equipment in the technical field of wood processing, in particular to a dust removal and explosion-proof device for wood dust explosion. Background technique [0002] With the development of social urbanization, technology, and humanization, the wood processing industry has developed vigorously, and more and more wood is processed and used, followed by the increase of wood dust and the emergence of wood dust explosion problems. . Dust explosion, dust refers to dispersed solid matter. Dust explosion refers to the explosion phenomenon that occurs when combustible dust suspended in the air touches an ignition source such as an open flame or an electric spark. Dust explosion refers to combustible dust within the explosion limit range, when encountering a heat source, the flame spreads instantly throughout the entire mixed dust space, the chemical reaction speed is extrem...
