High temperature bag-type dust collector for boiler

Abstract

The invention discloses a high temperature bag-type dust collector for a boiler. The high temperature bag type dust collector comprises a dust collector shell, wherein the inside of the dust collectorshell is separated into upper and lower two parts with a tubesheet, the upper part is a gas purification chamber, and the lower part is a dust collection chamber; a smoke outlet is formed in the sidewall of the gas purification chamber, and a smoke inlet is formed in the side wall of the dust collection chamber; a filter cloth bag with a plurality of upward openings is on the tubesheet, and is communicated with the upper gas purification chamber; a cyclone cylinder coats the filter cloth bag; the filter cloth bag is positioned at the center of the cyclone cylinder; the upper part of cyclonecylinder is a cylinder, while the lower part of the cyclone cylinder is a conical discharge channel having gradually reduced diameter; the top of the cyclone cylinder is connected with the tube sheet;the upper part of the cyclone cylinder runs through the bottom wall of the dust collection chamber, extends out of the dust collection chamber, and is fixed to the bottom wall of the dust collectionchamber; and a plurality of air inlet tubes are arranged at the upper part of the cyclone cylinder, and are tangentially connected with the upper part of the cyclone cylinder. The high temperature bag-type dust collector has a simple structure, can be used for protecting the cloth bag and has a good dust collection effect.

Description

technical field [0001] The invention relates to a high-temperature bag filter for boilers. Background technique [0002] The bag filter is the most commonly used dust removal device at present. Its working mechanism is: the coarse particles in the dust-containing gas collide with the inner wall of the dust-removing bag and fall directly into the ash hopper, and the fine particles in the dust-containing gas are filtered through the dust-removing bag, thereby realizing the dust removal of the dust-containing gas. However, in the above-mentioned dust removal process of the existing bag filter, most of the boiler flue gas is adsorbed on the filter surface of the dust bag, which seriously affects the filter function of the bag, so the dust on the bag needs to be cleaned frequently. Contents of the invention [0003] The invention provides a high-temperature bag filter for boilers. [0004] In order to solve the above problems, the technical solution adopted in the present inv...
