Flue gas purification rector, bag-type dust collector and dry type flue gas purification system

Abstract

The invention discloses a flue gas purification rector, a bag-type dust collector and a dry type flue gas purification system. The flue gas purification rector comprises a reactor body, wherein a gas discharging section of the reactor body is provided with a flue gas outlet which discharges flue gas to periphery along a radial direction; the flue gas outlet is used for being connected with a flue gas inlet of the bag-type dust collector which surrounds the outer part of the reactor body. Since the flue gas outlet of the flue gas purification rector discharges the flue gas to the periphery along the radial direction, the flue gas outlet is completely open; the bag-type dust collector surrounds the outer part of the reactor body so as to reduce an occupation space; the flue gas purification reactor can share a supporting platform with the bag-type dust collector, so as to reduce the use of a joint material; the flue gas is discharged to the periphery from the completely open flue gas outlet of the flue gas purification rector, and is discharged into the bag-type dust collector around the reactor, the flue gas which carries a great quantity of dust is more evenly diffused in the bag-type dust collector, average time for the flue gas to pass through a filter bag area is shortened, and the working state of the filter bag area more tends to be balanced.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a dry type flue gas purification reactor. It also relates to a bag filter matched with the flue gas purification reactor, and a dry flue gas purification system including the flue gas purification reactor. Background technique [0002] The dry-type flue gas purification system is mainly configured as a dry-type flue gas purification reactor and a downstream supporting bag filter, which can remove HCl, HF, SO 2 , SO 3 , dust, etc., to achieve collaborative purification of various pollutants, and has been more and more widely used in the field of flue gas purification. [0003] In the existing dry-type flue gas purification system, the connection mode between the dry-type flue gas purification reactor and the bag filter is mostly one-way connection, that is, the outlet of the dry-type flue gas purification reactor is connected to the inlet of the bag filter in one d...

AI Technical Summary

Problems solved by technology

[0003] In the existing dry-type flue gas purification system, the connection mode between the dry-type flue gas purification reactor and the bag filter is mostly one-way connection, that is, the outlet of the dry-type flue gas purification reactor is connected to the inlet of the bag filter in one direction. The latter is arranged in series in front and back, and the two devices are separated. Separate foundations and supports are used, which occupy a relatively large area, consume a large amount of equipment materials, and the flue gas carrying dust diffuses from the inlet to the outlet in the dust collector for a long time. In the bag filter, the load of the filter bag near the flue gas end is heavy, while the working load of the filter bag far away from the flue gas end is low, and the overall working state of the filter bag is relatively unbalanced

[0004] To sum up, how to solve the problems that the dry-type flue gas purification system occupies a large area, has many consumables, and the workload of the flue gas in the bag filter is unbalanced has become an urgent problem for those skilled in the art.
