Multi-stage deceleration type straw gas purifying device

Abstract

The invention discloses a multi-stage deceleration type straw gas purifying device. The multi-stage deceleration type straw gas purifying device comprises a box body, wherein the left upper corner andright upper corner of the box body are respectively connected with a gas inlet and a gas outlet; the lower surface of an upper top plate of the box body is connected with a plurality of upper separating plates which are arranged in the vertical direction; both sides of each upper separating plate are connected with the inner surface of the box body in a sealing way; a lower separating plate is arranged between the two adjacent upper separating plates; both sides of the lower separating plate are connected with the inner surface of the box body in a sealing way; the distance is set between thetop end of the lower separating plate and the upper top plate of the box body; the left lower corner and right lower corner of the box body are respectively connected with a water outlet and a waterinlet, the water outlet is connected with the water inlet end of a circulating water pump through a water pipe, and the water outlet end of the circulating water pump is connected with one end of a filter; the other end of the filter is connected with the water inlet; a plurality of filter nets are arranged in the filter, and a condensing device is wrapped to the exterior of a water pipe. The multi-stage deceleration type straw gas purifying device has the advantages that the dust in straw gas is effectively removed, and the blockage of a heat exchanger is avoided.

Description

technical field [0001] The invention specifically relates to a multi-stage deceleration straw gas purification device. Background technique [0002] Dry purification devices are often used for the purification of straw gas. However, there is a problem of blockage of the heat exchanger in the dry purification device. The main reason is that a large amount of dust is entrained in the tar contained in the straw gas entering the heat exchanger, which increases the viscosity of the tar. Therefore, it must be cleaned before entering the heat exchanger. Remove the dust in the gas. Because the gas temperature at the outlet of the gasifier is high and contains a large amount of tar, it has caused great difficulties in dust removal. Commonly used cyclone dust collectors have defects such as easy to block, difficult to clean, and short life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-stage deceleration straw g...
