Embodiment Construction

[0012] refer to figure 1 , figure 2 , The tar reflux pyrolysis gasification furnace includes a cylindrical furnace body 2 with a bottom, the upper part of the furnace body is open, and a U-shaped groove 3 is arranged on the top. After placement, a water seal structure is formed; the upper part of the furnace body is a sandwich structure with an air outlet 5, and the air outlet is connected to a water vapor separation device 6. The device is a closed box with an outlet 11 at the bottom. Serpentine condenser 7, serpentine condenser 7 is connected with cooking stove through pipeline; Furnace body bottom has air inlet hole 12, slag outlet hole 1, and air inlet hole 12 connects blower 9 externally through pipeline 10, and the outlet at the bottom of water vapor separation device 6 passes through The pipeline communicates with the air inlet hole 12. In order to facilitate the backflow of tar moisture, the position of the end of the pipeline near the air inlet is relatively low; T...

Abstract

The invention discloses a gasifier for refluxing and pyrolyzing tar. The gasifier comprises a sealed furnace body, wherein the upper part of the furnace body can be opened and be provided with a cover and a gas outlet, the outside of the gas outlet is connected with the inlet of a steam separation device, the bottom of the steam separation device is provided with an outlet; the lower part of the furnace body is provided with an intake and a slag hole, the outside of the wind hole is connected with a blower; an air-jetting themolysis gasifier is arranged on the lower end of the inside of the furnace body, the upper part of the air-jetting themolysis gasifier is opened, an air-jetting shield is covered on the gasifier body, the gap between the gasifier body and the air-jetting shield is used as an integral air-jetting path, an air-jetting gasification pyrolyzer is connected with the intake through a blast pipe, and the bottom outlet of the steam separation device is communicated with the intake through a pipe. The inside of the gasifier of the invention is provided with the air-jetting themolysis gasifier, the themolysis device and circular air-jetting device are integrated in the device of the invention, the cooled tar and moisture flow back to the inside of the gasifier to gasify, pyrolyze and burn; and the uniform air-jetting and uniform burning of the gasifier can be realized and the problem that coarse can not be burned by the gasifier is solved.

Description

technical field [0001] The invention relates to a combustion device, in particular to a tar reflux pyrolysis gasifier. Background technique [0002] At present, my country is building an environmentally friendly and ecological new countryside, using discarded crop stalks, chaff, straw, leaves, etc. as biomass fuels, which are used in gasifiers to generate gas for daily needs. However, there are many deficiencies in the use of the gasifier: firstly, due to tar blockage, the use effect is poor, and the use of three-way and oil-gas separation devices to solve the tar moisture generated by the gasifier combustion is usually to be cooled by the tar moisture After being collected in the container and then dumped, this treatment not only pollutes the environment, but also wastes resources, because tar and water are high-quality combustible gases after pyrolysis; The air distribution in the furnace is uneven, which is prone to partial burning, burn-through, sintering and other phen...
