Flue gas dust removal and desulfurization device of miniature industrial gas-fired boiler

Abstract

The invention discloses a flue gas dust removal and desulfurization device of a miniature industrial gas-fired boiler, wherein the device comprises a desulfurization tower; the bottom end of the desulfurization tower is fixedly mounted on a base, a water inlet pipe is arranged on one side of the desulfurization tower, and a water inlet valve is arranged on the water inlet pipe. According to the flue gas dust removal and desulfurization device of the miniature industrial gas-fired boiler, clean water enters into a ring pipe through a shunt pipe, after being guided by the cleaning pipe, the clean water flows down on the inner wall of a built-in frame body, dust and sulfuric acid attached to the built-in frame body are cleaned, a heating resistor is electrified to start heating, a heat absorption column absorbs heat and then transmits the heat to a heat conduction column, the heat conduction column heats the inner wall of the built-in frame body, and the inner wall of the built-in frame body is kept dry; according to the device, the inner wall of the built-in frame body can be synchronously cleaned in the spraying process, the dust and the sulfuric acid are prevented from being attached to the inner wall of the built-in frame body, and after desulfurization is completed, the interior of the built-in frame body is heated and dried, so that the interior of the tower body is kept dry.

Description

technical field [0001] The invention relates to the technical field of gas boilers, in particular to a flue gas dedusting and desulfurization device for a miniature industrial gas boiler. Background technique [0002] The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, and also have a small amount of application in industrial production. Boilers that generate steam are called steam boilers, often referred to as boilers for short, and are mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises. Harmful gases such as sulfuric acid, so dust removal and desulfurizatio...

AI Technical Summary

Problems solved by technology

[0004] 1. In the process of dust removal and desulfurization by spraying, some spray water with dust and sulfuric acid will hang on the inner wall of the desulfurization tower, gradually increasing the concentration of dust and sulfuric acid inside the desulfurization tower, It is not conducive to long-term effective dust removal and desulfurization;

[0005] 2. The inner wall of the desulfurization tower body is in a humid environment for a long time, which may easily lead to water seepage at the joints inside the desulfurization tower body, affecting the normal use of the desulfurization tower body
