Embodiment Construction

[0004] The device collects dust through a dry filter tank before vacuuming the system, and filters some coarse dust through a dry screen filter into the re-entry oil filter tank. The main purpose of the filter tank is to eliminate fine dust . Then the dust-free gas enters the chemical filter tank, the purpose is to turn the harmful gas after the dust has been removed into a harmless gas through chemical reaction, so as to achieve the purpose of safe discharge.

Abstract

A sintering furnace volatile matter collecting device relates to environment friendly sintering equipment, in particular to a collecting device of sintering furnace volatile matter. The prior sintering furnace, which frequently discharges a great amount of volatile dust and harmful gas in the air and pollutes the air, can not realize the goal of environmental protection; moreover, the volatile matter is easy to pollute a vacuum machine set and causes the damage of the vacuum machine set. The device, which collects dust through a dry type filtering tank in front of an vacuumizing system, filters coarser dust through a screen dry filter into an oil refilling type filtering tank; moreover, the filtering tank mainly aims to eliminate fine dust; then, dustless gas is fed into a chemical filtering tank body in order to turn the dedust harmful gas into harmless gas in a chemical reaction mode, thereby reaching the goal of safe emission.

Description

technical field [0001] The invention relates to an environment-friendly sintering equipment, in particular to a volatile matter collection device for a sintering furnace. Background technique [0002] The current sintering furnace often has a large amount of volatile dust and harmful gas directly entering the air, polluting the air and failing to achieve the purpose of environmental protection. Moreover, the volatilized substances are easy to contaminate the vacuum unit and cause damage to the vacuum unit. Contents of the invention [0003] The invention mainly adds a trapping device before the vacuum system, and adopts multi-stage supplementary tank filtration to achieve the purpose of completely trapping dust and harmful gas. It mainly consists of a vacuum furnace body, a dry filter tank, an oil filter tank and a chemical reaction filter tank. detailed description [0004] The device collects dust through a dry filter tank before vacuuming the system, and filters som...
