Abstract

The utility model discloses a gas filtration and purification device for a straw gasification stove. The purification device is composed of purification pipes which are arranged at intervals mutually and vertically, a gas delivery pipe connected with the straw gasification stove extends into the lower portion of a primary purifying pipe, the upper portion of the primary purifying pipe is communicated with the upper portion of a secondary purifying pipe through a pipe, the secondary purifying pipe is composed of a gas inlet purifying pipe and a gas outlet purifying pipe, the two purifying pipes are communicated through a pipe with a shape like a Chinese character 'Ji', two ends of the pipe with the shape like the Chinese character 'Ji' respectively extend into the lower portion of the two purifying pipes, the gas outlet purifying pipe is connected with a terminal purifying pipe through a pipe, and a gas outlet pipe penetrating from the lower portion of the terminal purifying pipe upwards is connected with the stove. The gas filtration and purification device can fully purify materials such as tar, water and the like in sediment gas and can improve the gas purification degree.

Description

The combustion gas filtering and purifying of stalk gasifier

Technical field

The utility model belongs to the combustion gas filtering and purifying of the improvement of gasifying stalk furnace structure, particularly stalk gasifier.

Background technology

Existing stalk gasifier is environment friendly and pollution-free and obtained wide popularization and application at the vast both urban and rural area of China with it.Stalk gasifier utilizes stalk, flyash, plastics and various flammable foreign material to be raw material, can produce high-quality combustion gas under the smoldering situation, heats up water for people and cooks.Its weak point is that traditional stalk gasifier directly is introduced into the cooking stove internal combustion with the combustion gas that produces, owing to mix materials such as tar and moisture are arranged in the combustion gas, influences the combustion efficiency of combustion gas.

The utility model content

The purpose of this utility model is to provide a kind of combustion gas filtering and purifying of stalk gasifier, it is simple in structure, is used materials such as the tar in sedimentation effectively, the purifying gas, moisture with stalk gasifier, improve the degree of purity of combustion gas, improve combustion efficiency.

The purpose of this utility model is achieved in that a kind of combustion gas filtering and purifying of stalk gasifier, the purification pipe that this purifier is arranged by mutual vertical spacing is formed, the appendix that links to each other with stalk gasifier stretches in the bottom of primary purifying pipe, the top of primary purifying pipe is connected by the top of pipe with the secondary stage purified pipe, the secondary stage purified pipe is made up of the air inlet purification pipe and the purification pipe of giving vent to anger, be connected by more than one font pipes between these two purification pipes, the two ends of a few font pipes extend respectively in the bottom of these two purification pipes, the purification pipe of giving vent to anger links to each other with the final stage purification pipe by pipe, and the escape pipe that upwards passes in the final stage purification pipe bottom links to each other with cooking stove.

The utility model can be used with any type of stalk gasifier, be input to by the combustion gas that produces in the stalk gasifier and purify sedimentation in the purification pipe, material such as tar and moisture runs into and purifies the bottom that condensation liquefy behind the tube wall is pooled to purification pipe and drain, each purification pipe is passed through in combustion gas successively, operation repeatedly from down to up, it is pure to become gradually, inputs to the cooking stove internal combustion by escape pipe at last.The utility model is simple in structure, is used with stalk gasifier, and materials such as the tar in sedimentation effectively, the purifying gas, moisture, dust improve the degree of purity of combustion gas, improve combustion efficiency.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Accompanying drawing is a main TV structure schematic diagram of the present utility model.

The specific embodiment

A kind of combustion gas filtering and purifying of stalk gasifier, as shown in drawings, the purification pipe that this purifier is arranged by mutual vertical spacing is formed, the appendix 3 that links to each other with stalk gasifier stretches in the bottom of primary purifying pipe 2, the top of primary purifying pipe 2 is connected by the top of pipe 1 with the secondary stage purified pipe, the secondary stage purified pipe is made up of the air inlet purification pipe 10 and the purification pipe 11 of giving vent to anger, be connected by more than one font pipes 12 between these two purification pipes, the two ends of a few font pipes 12 extend this two purification pipes 10 respectively, in 11 the bottom, the purification pipe 11 of giving vent to anger links to each other with final stage purification pipe 13 by pipe, and the escape pipe 5 that upwards passes in final stage purification pipe 13 bottoms links to each other with cooking stove 6.

The bottom of each purification pipe all is connected with a discharging tube 4, materials such as tar that discharging tube 4 compiles bottom the eliminating purification pipe and moisture.

When the utility model used, a ventilation duct 7 of drawing from air blast together caused in the cooking stove 6 with escape pipe 5.

The utility model can also be provided with several purification pipes more, so that further improve the gas-purification effect.
