Novel environment-protecting and energy-saving industrial boiler system

Abstract

The invention discloses a novel environment-protecting and energy-saving industrial boiler system. The system mainly consists of an electric control cabinet, a coal feeder, a combustion chamber, a furnace body, an air preheater, a multi-pipe dust remover, a water film dust remover and a chimney, wherein the lower part of the furnace body is the combustion chamber; the furnace body has a hearth temperature measuring port, and is provided with a smoke outlet in the back part; the combustion chamber is provided with a coal hopper at the front part and a secondary air port in the back part; the smoke outlet is connected with the air preheater by a smoke way I; the air preheater is connected with the multi-pipe dust remover by a smoke way II; the multi-pipe dust remover is connected with the lower part of the water film dust remover by a smoke way III; an air blower is connected with the air preheater by an air way I; one end of the an air way II is connected with the air preheater, and the other end is connected with an air chamber at the bottom of the combustion chamber; a secondary fan is connected with the air preheater by an air way III; and one end of an air way IV is connected with the air preheater, and the other end is connected with the secondary air port in the back part of the combustion chamber. The system can effectively reduce the boiler smoke discharge temperature, improve the system heat efficiency, realize the clean utilization of coals and control the displacements of atmospheric pollutants of sulfur dioxide, nitric oxide and industrial smoke dust in the fire coal control process.

Description

technical field [0001] The invention belongs to the technical field of industrial boiler systems, and relates to a novel environment-friendly and energy-saving horizontal chain industrial boiler system. Background technique [0002] Since the beginning of 2013, China has experienced large-scale and continuous smog. According to statistics, the areas affected by smog include North China Plain, Huanghuai, Jianghuai, Jianghan, Jiangnan, and northern South China. The affected area accounts for about 1 / 4 of the country's land area, and the affected population is about 600 million. As the weather turns cooler and some areas begin to supply heat one after another, smog in the central and eastern regions of China is showing a high incidence trend; coal-fired boilers are mainly responsible for the occurrence of smog weather. The three major components of smog are sulfur dioxide, nitrogen oxides and Inhaled particulate matter, all of which are components of exhaust gas emitted by coa...
