Problems solved by technology

But the biggest defect of the water seal is that the water is easily polluted by tar. After using it for a period of time, the water in the water seal tank is almost half of water and tar, which not only has a strong smell, but also pollutes the furnace body and the environment.

Embodiment Construction

[0020] Such as figure 1 As shown, an annular sealing groove 2 is arranged inside the top of the furnace body 1, and the bottom of the sealing groove 2 communicates with the blower 4 through the air inlet pipe 3. When the furnace cover 5 is covered, the air inlet 6 of the sealing groove 2 is located in the furnace Inside the outer edge 7 of the cover, there is an air inlet channel 9 between the top of the furnace cover 5 and the top of the inner ring 8 of the sealing groove 2 . In this embodiment, the air inlet pipe 3 , the supply pipe 10 entering the furnace bottom and the oxygen distribution pipe 12 entering the stove body 11 are all in communication with the blower 4 .

[0021] Such as figure 2 As shown, an annular gasket 13 is arranged in the sealing groove 2, and the annular gasket 13 forms an air inlet chamber 14 with the bottom and both sides of the sealing groove 2. Air intake gaps 16 are formed between the inner rings 8 of the inner rings.

Abstract

The invention relates to a sealing device for a biomass gasification furnace. In the sealing device, a seal groove (2) is formed on the top of the biomass gasification furnace; the seal groove (2) is communicated with a blast blower (4) through an air inlet pipe (3); when a furnace cover (5) covers the furnace, an air inlet (6) of the air inlet pipe (3) is positioned on a furnace cover outer edge (7); and an air inlet channel (9) is reserved between an inner ring (8) of the seal groove (2) and the top part of the furnace cover (5). The sealing device adopts pressurized seal, without using water, so the sealing device has the advantages of convenient operation, no tar odor and capacity of reducing emission of the tar and increasing gas-making time.

Description

technical field [0001] The invention relates to a biomass gasification furnace, in particular, it provides a sealing device for a biomass gasification furnace. Background technique [0002] Biomass gas is a combustible gas produced by using plant fuels through gas furnaces under airtight and relatively anoxic conditions, using dry refraction pyrolysis and thermochemical oxidation methods. Although there are many studies on biomass domestic gasifiers, and many biomass domestic gasifier products have appeared on the market, they are difficult to be widely promoted. One of the important reasons is that the biomass tar in the produced gas is difficult to remove. An "integrated composite gasifier" (200910043224.X) disclosed in a Chinese patent better solves the problem of biomass tar. However, the existing biomass gas furnace generally adopts the seal that the gasket is tightened with bolts, which is not only cumbersome to operate, but also cannot be completely sealed. Because ...
