Problems solved by technology

The choice of fuel for this gasifier is limited, grass-like fuel cannot be used, otherwise the gasification effect will not be good, and this will not solve the existing problem of straw being burned in the field
At the same time, the existing method of using water spray to filter combustible gas has a poor filtering effect, and the filtered water will pollute the environment after being discharged.

Embodiment 1

[0015] Embodiment 1, with reference to the accompanying drawings, a generator for efficiently applying biomass fuel to generate combustible gas, including a gasifier 18, a smoke filter tube 15 and an air pump 13, the gasifier 18 includes a furnace drum 17, and the lower end of the furnace drum 17 is connected to There is an ash discharge channel 20, and a furnace bar or a furnace plate 19 with a through hole is provided at the junction of the furnace tube 17 and the ash discharge channel 20, and the ash enters the ash discharge channel 20 from the gap of the furnace bar or the through hole of the furnace plate 19 to be discharged. An air outlet is provided on the furnace wall at the lower part of the furnace tube 17; the smoke filter tube 15 includes a sealed housing 14, and a filter element 21 is arranged inside the sealed housing 14, and the upper part of the sealed housing 14 passes through the air outlet of the pipeline and the gasifier 18 The air outlet pipeline is connect...

Embodiment 2

[0017] Embodiment 2, in the generating device described in embodiment 1, the pipeline between the gasifier 18 and the smoke filter tube 15 is provided with a fire isolation device 16 to prevent sparks in the gasifier 18 from entering into the smoke filter tube 15 and igniting The filter element 21 improves the safety of the equipment.

Embodiment 3

[0018] Embodiment 3, in the generating device described in Embodiment 2, the fire isolation device 16 includes a water tank, and the outlet of the pipeline connected to the air outlet of the gasifier 18 is arranged in the water tank, and the upper part of the water tank passes through the pipeline and the smoke filter tube 15 The upper part of the sealed housing 14 is connected, water is housed in the water tank, and the outlet of the pipeline connected to the air outlet of the gasifier 18 is not in the water, and the gas coming out from the gasifier 18 is filtered through the water in the water tank and then released from the gasification furnace 18. The pipeline on the top of the water tank enters the smoke filter tube 15, which can eliminate naked flames.

Abstract

The invention relates to a generation device for generating combustible gas by utilizing a biomass fuel efficiently. The generation device comprises a gasification furnace, a smoke filtering drum and an air pump, wherein the gasification furnace comprises a furnace drum, the lower end of the furnace drum is connected with a dust discharge channel, and a joint of the furnace drum and the dust discharge channel is provided with a fire-grate bar or a furnace plate with a through hole; and the smoke filtering drum comprises a sealing shell, a filter element is arranged in the sealing shell, the upper part of the sealing shell is connected with the gasification furnace through a pipeline, and the lower part of the sealing shell is connected with an air outlet pipeline. According to the gasification furnace and the smoke filtering drum, the biomass fuel generates gas in the gasification furnace, the gas is filtered by the smoke filtering drum, a grass cake can be used as the filter element of the smoke filtering drum to remove the unpleasant smell of tar, smoke dust and the like in the combustible gas, and the grass cake which is used for a long time in the smoke filtering drum can be taken out and used as gasification raw material, and is recycled to save the cost. The generation device for generating the combustible gas by utilizing the biomass fuel efficiently disclosed by the invention has the characteristics of simple structure, high filtering and purifying rate, environmental protection and no pollution.

Description

technical field [0001] The invention relates to a generator of combustible gas, in particular to a generator for generating combustible gas by efficiently using biomass fuel. Background technique [0002] In the prior art, biomass fuels such as corncobs, rice husks, wood chips and other materials are directly placed in the gasifier for anaerobic combustion, and the resulting combustible gas is filtered by water spray or directly transported to the storage tank by an air pump. Store in an air bag. The choice of fuel for this gasifier is limited, and grass-like fuel cannot be used, otherwise the gasification effect will not be good, and this cannot solve the problem of the existing straw being burned in the field. At the same time, the existing method of using water spray to filter combustible gas has poor filtering effect, and the filtered water will pollute the environment after being discharged. Contents of the invention [0003] The technical problem to be solved by t...
