Tube bundle dust remover with flue gas cooling function

Abstract

The invention discloses a tube bundle dust remover with a flue gas cooling function, which comprises a tube body, a water supply tank mounted on the tube body, a cylindrical pressurizing water tank with one end mounted at an air inlet in the bottom end of the tube body, and a plurality of guide tubes connected with the water supply tank and the cylindrical pressurizing water tank, wherein a pressurizing water pump is mounted on each of the plurality of guide tubes; an atomizing nozzle is mounted at the axis of the cylindrical pressurizing water tank in a communicating manner; cooling water issprayed out and diffused through the atomizing nozzle; part of the fine liquid drops absorb the heat of the flue gas and evaporate; therefore, the temperature of the flue gas entering the tube body isreduced; the unevaporated fine liquid drops wrap the particles in the flue gas, so that the situation that the particles enter the flue gas again after colliding and rebounding with the inner wall ofthe tube body is greatly avoided, the particles in the flue gas can be captured by a liquid film on the inner wall of the tube body, and the dust removal effect on the flue gas can be enhanced whilethe tube bundle dust remover is protected.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of dust removal equipment, and in particular to a tube bundle dust collector with a flue gas cooling function. Background technique [0002] In the production process of gypsum board, heat source is required for clinker calcination and gypsum board drying. Most factories use coal-fired fluidized bed for heat supply. Coal-fired will produce sulfur dioxide, nitrogen oxides, dust particles and other substances. To eliminate the dust particles in the flue gas, it is necessary to add dust removal equipment at the outlet of the flue gas discharge tower. The current dust removal equipment is diversified, and the tube bundle dust collector is the most commonly used equipment. [0003] However, the tube bundle dust collector is generally made of modified PP material with a temperature resistance of 80°C. When the original heat system runs abnormally or in an emergency, the temperature at the...

Problems solved by technology

[0005] For this reason, the embodiment of the present invention provides a tube bundle dust collector with a flue gas cooling function to solve the problem in the prior art that the service life of the tube bundle dust collector is reduced due to the inability of the tube bundle dust collector to cool the incoming high temperature flue gas. question
