Device and method for high polymer material burning harmless treatment

Abstract

The invention discloses a device and a method for high polymer material burning harmless treatment. A high temperature pyrolysis tunnel furnace with an insulating layer is arranged between a combustion furnace and a heat exchange device, a smoke inlet of the tunnel furnace is connected with a smoke outlet of the combustion furnace, and a smoke outlet of the tunnel furnace is connected with the heat exchange device. A tunnel in the tunnel furnace is isolated to be an A tunnel cavity, a B tunnel cavity and a C tunnel cavity which are communicated in a head-and-tail mode and in a shape of an S through a front partition wall and a back partition wall. A furnace opening fan, a furnace opening temperature measurement device and an external heating source are respectively arranged at the smoke inlet of the tunnel furnace. An excess air measurement device and a furnace end temperature measurement device are respectively arranged at the smoke outlet of the tunnel furnace. A tunnel temperature measurement device and a tunnel fan are respectively arranged in the middle of the tunnel furnace. Dioxin, cyanide and other toxic gas in the smoke can complete a pintsch process to become nontoxic micromolecule gas, harmless clean discharge of the combustion furnace is achieved, pollution to the neighboring environment is reduced, and safety hidden dangers of people are removed.

Description

technical field [0001] The invention relates to an incineration harmless treatment device and method, more specifically a polymer material incineration harmless treatment device and method, which is suitable for the harmless incineration treatment of polymer waste. Background technique [0002] Materials such as plastics, thermosetting plastics, and polyurethane are generally called polymer materials. When products made of polymer materials are discarded and incinerated, toxic gases such as dioxins and cyanides that are difficult to handle can be produced. It is difficult to achieve clean discharge of these toxic gases through the flue gas purification device of the incinerator, and it is easy to form secondary pollution. The condition for sufficient decomposition of dioxin and cyanide is that the residence time in the high temperature zone above 800°C is not less than 2 seconds. However, the existing incinerators cannot realize this condition structurally, and cannot solve...
