Gas-solid separation device with dusting brush

Abstract

The invention discloses a gas-solid separation device with a dusting brush. The device comprises a device body provided with a treatment space inside, a crude gas inlet arranged on one side of the device body, a gas outlet arranged on the other side of the device body, an intake chamber formed on the upper part of the treatment space, a dust chamber formed on the lower part of the treatment space, a filter element which is arranged in the treatment space and partitions the intake chamber and the dust chamber, and a dust removal system, wherein the filter element is provided with at least one through hole which is communicated with the intake chamber and the dust chamber, the crude gas inlet is communicated with the intake chamber, the side wall of the filter element seals the gas outlet, and the dust removal system comprises a driving part and at least one dusting brush which can rotate and / or perform reciprocating movement in the corresponding at least one through hole under the driving of the driving part. The device adopts the dusting brush to effectively brush off solid particles adhered to the inner wall of the through hole of the filter element to avoid the phenomenon that the solid particles block the filter element, thereby ensuring the steady operation of the device.

Description

technical field [0001] The invention relates to a filter device, in particular to a gas-solid separation device used in a biomass energy conversion system. Background technique [0002] With the continuous development of the world economy, energy and environmental issues have become increasingly prominent. The main energy sources currently used by human beings are oil, natural gas and coal. According to the statistics of the International Energy Agency, the lifespan of these three kinds of energy for human exploitation on the earth is only 40 years, 50 years and 240 years respectively. The development of new energy has become a major issue related to the sustainable development of human society. [0003] Biomass energy is the solar energy stored in plants by the photosynthesis of plants and solar energy. It is estimated that the annual energy stored in plants is equivalent to 10 times the world's main fuel consumption, while the utilization of energy as energy is less tha...

Problems solved by technology

However, it can be seen from the above description that the patent No. CN200510057215.8 has the following disadvantages: the filter element of the gas-solid separator in the prior art is easily blocked by biomass particles after a period of use, resulting in the flow of pyrolysis gas Unsmooth, which leads to loss of productivity, so it must be manually cleaned or replaced on a regular basis, which will cause considerable trouble to production
