Waste gas treatment device of coal-fired conduction oil boiler

Abstract

The invention relates to a waste gas treatment device of a coal-fired conduction oil boiler. The waste gas treatment device of the coal-fired conduction oil boiler comprises the coal-fired conduction oil boiler, wherein the coal-fired conduction oil boiler is provided with a hearth, a gas outlet is formed in the top of the hearth, and a gas outlet pipeline is fixedly connected to the exterior of the gas outlet; a waste gas treatment device body is arranged outside the coal-fired conduction oil boiler, and comprises an air blower, a siphoning pipeline, a multi-tube dust cleaner, a flue and a sulfur compound recovery device, wherein the air blower is communicated with the multi-tube dust cleaner through the siphoning pipeline, the gas outlet pipeline is communicated with the siphoning pipeline, the included angle alpha between the gas outlet pipeline and the siphoning pipeline is smaller than 90 degrees, and the multi-tube dust cleaner is communicated with the sulfur compound recovery device through the flue. According to the waste gas treatment device of the coal-fired conduction oil boiler, ventilation can be promoted, combustion efficiency can be improved, gases, such as sulfur dioxide and hydrogen sulfide, in the dry gas can be effectively recovered, waste gas is emitted into the atmosphere, and pollutant emission is reduced to the maximum extent.

Description

Technical field [0001] The invention relates to the technical field of heat-conducting oil boiler equipment, in particular to a waste gas treatment device for a coal-fired heat-conducting oil boiler. Background technique [0002] Many existing chemical processing plants in China use a large number of heat-conducting oil boilers, and the processing equipment will produce some combustible gas, such as dry gas, which contains some sulfur dioxide and hydrogen sulfide. Hydrogen sulfide must be fully burned before it can be discharged into the atmosphere, and the flue gas must be desulfurized to minimize the emission of pollutants. A large amount of waste gas from chemical plants is directly passed into the torch to burn, and energy waste is serious. Summary of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems of poor air fluidity in the furnace, insufficient gas combustion, and serious waste of direct combustion of su...
