Abstract

The invention discloses an emergent exhausting system for high-temperature smoke. The system comprises a special-shaped flue and a parallel four-connecting rod mechanism, wherein the special-shaped flue is used for exhausting smoke; the special-shaped flue is provided with a narrow part throat part; the parallel four-connecting rod mechanism comprises four hinging shafts; two hinging shafts are fixedly arranged on the side wall of the special-shaped flue to form an upper fixed hinging shaft and a lower fixed hinging shaft; the upper parallel rod of the parallel four-connecting rod mechanism is connected to a piston rod of an air cylinder through one hinging shaft; the throat part of the special-shaped flue is provided with a sealing door; the lower part of the throat part is provided with a heat-isolating door; the heat-isolating door is connected with the upper fixed hinging shaft through an upper connecting frame rod; the heat-isolating door is connected with the lower fixed hinging shaft through a lower connecting frame rod; and the air cylinder pushes the parallel four-connecting rod mechanism to rotate clockwise or counterclockwise through the piston rod to seal and open the sealing door and the heat-isolating door. The problems of high-temperature corrosion and acidic gas corrosion of the traditional pressure relief device are solved.

Description

technical field [0001] The invention relates to the technical field of hazardous waste incineration, in particular, the invention relates to an emergency high-temperature flue gas discharge system for removing positive-pressure flue gas in a furnace when deflagration occurs in a hazardous waste incineration system. Background technique [0002] In the hazardous waste incineration device, under normal working conditions, the combustion chamber should ensure the state of negative pressure incineration in the furnace to ensure that the incineration flue gas does not leak out and pollute the working environment; due to the diversity of materials incinerated by the hazardous waste incinerator, when incinerating Or when explosive materials can be produced, the pressure in the furnace will rise instantaneously, which is higher than the outdoor ambient air pressure, and the polluted gas in the furnace will leak into the ambient space and pollute the working environment. Therefore, th...
