Biomass gas purifier and gasification purification device

Abstract

The invention relates to a biomass fuel gas purifier and a gasification purification device. The purifier (2) comprises a cooling cavity (214), a fuel gas purification set (4) and a tar collection cavity (216). The fuel gas purification group comprises a middle pipeline (410) arranged in the cooling cavity and a plurality of peripheral pipelines internally provided with spiral augers (401), and the bottoms of all the pipelines are opened and extend into the tar collection cavity; the plurality of peripheral pipelines are uniformly grouped, the pipelines in each group are communicated in sequence, the head pipeline is communicated with a purifier air inlet (201), and the tail pipeline is communicated with the middle pipeline; a spray header (403) and a filter screen (402) are arranged in the middle pipeline, and the spray header is used for spraying liquid in the tar collecting cavity. According to the device, fuel gas can be purified in four different modes of cooling, swirling, showering and filtering, purification is thorough, the purity of the fuel gas is high, the structural design is reasonable and compact, and the occupied space is small; meanwhile, the bottoms of the pipelines in the gas purification set are in a liquid sealing mode, the fire retardance effect is achieved, and safety and reliability are achieved.

Description

technical field

[0001] The present application relates to the technical field of biomass energy utilization, in particular to a biomass gas purifier and a gasification purification device. Background technique

[0002] With the improvement of the quality of life of rural residents and the change of lifestyle, the resource pressure and environmental problems in rural areas have become prominent. In the case of high electricity costs, coal has basically replaced straw and branches in daily life such as cooking, drinking and heating. However, coal resources are increasingly scarce, and the accumulation of resources such as straw and branches has had a great impact on rural production. Farmers usually use field incineration, which not only causes a lot of pollution to the environment, but also poses a great safety hazard.

[0003] In view of this serious problem highlighted in rural areas, considering that rural branches, straw, straw and livestock manure are all important ren...

Examples

Embodiment Construction

[0033] The upper part of the cooling chamber 214 is provided with a water replenishment port 204, the middle and lower part is provided with a cooling chamber liquid level port 206, and the top is equipped with a breathing valve 203; through the cooling chamber water replenishment port 204 and the cooling chamber liquid level port 206, an automatic water replenishment valve 202 can be installed to realize Automatic replenishment of cooling chamber 214.

[0034] The tar collection chamber 216 is located at the lower part of the purifier, and its lower part is in the shape of an inverted cone (the bottom plate is a conical plate 217, which is easy for liquid to flow out), and the end of the conical shape is a liquid outlet 212; during the working process, the gas is purified by the gas purification group 4 The resulting tar mixture will enter the tar collection chamber 216 through the bottom of the pipeline, and the tar mixture in the tar collection chamber 216 will liquid-seal t...
