Abstract

The invention provides a gas-solid separation device for gas easy to dew. The gas-solid separation device comprises a gas buffer cavity, a filtering mechanism, a heating body, a back flushing mechanism, a differential pressure type transmitter and a gas extraction mechanism, wherein the filtering mechanism is arranged in the gas buffer cavity, the heating body is arranged outside the gas buffer cavity in a sleeving mode, a differential pressure type transmitter is connected between the gas inlet and the gas outlet of the gas buffer cavity through a pipeline; one end of the blowback mechanism is connected with the compressed air supply mechanism, and the other end of the blowback mechanism extends into the gas buffer cavity; and a gas inlet of the gas buffer cavity is connected with a gas outlet of the external reaction cavity, and a gas outlet of the gas buffer cavity is communicated with the gas extraction mechanism. According to the invention, condensation of gas easy to dew in the separation process can be avoided, and filtration of the gas easy to dew is realized. Meanwhile, the filter has the function of separating and collecting intercepted materials. According to the test, gas with the water content of 60 vol.% is tested, the heat preservation temperature of the gas-solid separation device is 200 DEG C, and the filtering effect of particles with the particle size of 5 micrometers or above can reach 95% or above.

Description

technical field [0001] The invention belongs to the fields of environmental protection and chemical industry, and in particular relates to a gas-solid separation device for gases prone to condensation. Background technique [0002] During the gas-solid reaction between dew-condensing gas and solid (powder), a large amount of tail gas containing dew-condensing gas and solid powder will be produced. The gas is easy to condense and condense, which will block the filter and affect the gas-solid separation effect; on the other hand, the material trapped by the filter on the gas-solid separation device needs to be removed in time, otherwise the life of the filter will be affected. Therefore, there is an urgent need for a gas-solid separation device that can filter condensation-prone gas and can remove solid particles from the filter in time. Contents of the invention [0003] The present invention is proposed in order to overcome the shortcomings in the prior art, and its purpo...
