Problems solved by technology

However, the problems existing in the existing cloth bag filter are: due to the high temperature of the biomass combustible gas, it is easy to cause a decrease in the service life of the bag. The increase in the number of blowing times is not conducive to energy saving and consumption reduction. More importantly, the filter holes of the bag are relatively large, making it difficult to filter tiny ash impurities, making the filtering effect of the filter unsatisfactory.

Embodiment Construction

[0020] Such as figure 1 As shown, the main body of the filter is a cylinder, and a filter unit 3 and a blowback device 4 are assembled inside the cylinder. The cylinder is composed of a head 5, a cylinder 2 and a cone 1. The top of the head 5 is provided with an air outlet 6 , the side of the cylinder 2 is provided with an air inlet 7 , and the bottom of the cone 1 is provided with an ash outlet 9 .

[0021] Such as figure 2 As shown, the filter unit 3 is composed of an orifice plate 12, 48 ceramic filter elements 11, a bracket and a suspension rod 17. The orifice plate 12 is fitted at the contact of the head 5 and the cylinder 2 . The orifice plate is provided with 8 rows × 6 columns = 48 through holes, and the ceramic filter element is inserted in the through holes. In order to prevent the lower part of the filter element from shaking, the orifice plate 12 is vertically connected to the suspension rod 17, and the suspension rod is used to lift a bracket, and the bracket...

Abstract

The invention disclose a biogas filter, wherein a filtrating unit composed of a plurality of ceramic filter cores for filtrating ash impurity and impurities in the biogas, is arranged in a cylinder. When the high-temperature biogas passes through the ceramic membrane filter cores of the filter, the dust in gas flow impacts the ceramic membrane filter cores and is held up. The high-temperature combustible gas with tar passes through the ceramic membrane filter cores, to separate the gas flow and a grain flow for removing dust in gas. The filter has the characteristics of high temperature resistance and good filtrating effect.

Description

technical field [0001] The invention belongs to industrial filter equipment, in particular to a filter for filtering ash impurities in bio-combustible gas. Background technique [0002] Biomass gas is a kind of biomass energy. It converts solid biomass raw materials into combustible gas under high temperature conditions through biomass gasification technology to replace traditional natural gas resources. [0003] Usually, due to the poor burnout of the biomass raw material itself, the biomass gas produced by the biomass gasifier contains a large amount of fly ash, solid particles and tar. In order to reduce corrosion of downstream equipment and blockage of pipelines by alkaline dust in combustible gas, and to achieve efficient purification of combustible gas with low energy consumption, gas-solid separation must be carried out directly under high temperature conditions. At the same time, in the process of gas purification, problems such as equipment corrosion and pipeline b...
