The invention belongs to the field of heating technology, and in particular relates to a heating device for a purification room behind a firewall in a coiled biomass gasification station, including a gasifier and a dry dust collector arranged in the gasification room. The gasifier and the dry dust collector are connected through a first pipe. A coil is wound around the dry dust collector. One end of the coil is connected to the axial flow fan through a second pipe, and the other end of the coil is connected to the axial flow fan. One end of the insulation pipe is connected, and the other end of the insulation pipe passes through the air outlet on the firewall added between the gasification room and the purification room. It is set in the purification room. There is a return air outlet in the purification room. The installation of firewalls in the gasification room and purification room eliminates safety hazards and solves the problem that the purification room cannot be heated in winter, resulting in freezing and cracking of the equipment in the purification room. Moreover, the heat used for heating comes from the waste heat of the biomass gasification reaction, which can meet the economic requirements. Heating needs.
Description
technical field [0001] The invention belongs to the technical field of heating, in particular to a heating device for a purification room after a firewall is installed in a biomass gasification station. Background technique [0002] In the biomass gasification process, the biomass gasification station is divided into two parts: the gasification room and the purification room; the dry dust collector in the gasification room and the pipelines connected to it are due to the high-temperature biomass gas produced by the gasifier , so that the surface temperature can reach hundreds of degrees Celsius, especially after the gasification device has been running for a long time, the pipe wall will even appear red hot, which is equivalent to an open flame, so once a gas leak occurs in the gasification station, it will be Fire and explosion accidents are very likely to occur; therefore, installing a firewall between the gasification room and the purification room can isolate the high-te...
