Tar processing and reburning device for household straw gasifier

Abstract

The invention provides a tar processing and reburning device for a household straw gasifier. A gas outlet of the gasifier is connected with inlet ends of first-stage cooling gas pipes, the first-stage cooling gas pipes are arranged in a cooling water tank in parallel, the other ports of the first-stage cooling gas pipes are arranged outside the cooling water tank and locked by using a locking cover, the multiple first-stage cooling gas pipes in the cooling water tank are communicated mutually, and the first-stage cooling gas pipes at the lower part of the cooling water tank are communicated with a tar backflow tank; outlets of the first-stage cooling gas pipes are communicated with a gas inlet of a second-stage cooling gas pipe, an air cooling pipe is sleeved at the periphery of the second-stage cooling gas pipe in a clearance way, and a fan is communicated with the upper part of the air cooling pipe; and an outlet of the second-stage cooling gas pipe is communicated with a pipe whichcommunicates a tar filter and a tar backflow tank. According to the invention, a clear production system with self closed cycle is formed, the improvement of the rural environment can be promoted, and a broader new pathway can be provided for creating energy-efficient and environmentally-friendly rural areas.

Description

technical field [0001] The invention relates to a household type straw gasification furnace, in particular to a tar treatment and returning combustion device of the household type straw gasification furnace. Background technique [0002] Most household straw gasifiers currently on the market do not have a tar treatment device, some use infrared burners to burn, and some use some simple tar treatment devices, which cannot completely treat the tar, causing tar to block the pipe network, Stove burners and odors will be generated after burning, and the treated tar and water vapor mixture cannot be returned to the furnace for combustion, which will cause secondary pollution of soil and water sources. Contents of the invention [0003] The invention provides a tar treatment and back-burning device of a household straw gasification furnace, which can solve the problem of tar blocking the pipe network, the stove, the generation of peculiar smell after burning, and the back-...
