Abstract

The invention discloses an environment-friendly exhaust gas recovering device for a chain-grate boiler. The environment-friendly exhaust gas recovering device is arranged on one side of an exhaust gas output pipe of the chain-grate boiler, and comprises an exhaust gas recovering pipe; the chain-grate boiler comprises a combustion system and an electrical control assembly; one end of the exhaust gas recovering pipe is connected to and communicates with the exhaust gas output pipe from the side surface. The environment-friendly exhaust gas recovering device is further characterized in that an induced draft fan is arranged in the exhaust gas recovering pipe; an electromagnetic distribution valve is arranged at a joint of the exhaust gas output pipe and the exhaust gas recovering pipe; a temperature sensor is arranged in the chain-grate boiler; and the electrical control assembly is connected with the temperature sensor, the electromagnetic distribution valve and the induced draft fan. By the intelligent control, the environment-friendly exhaust gas recovering device realizes recycling of exhaust gas and reduces discharging.

Description

technical field [0001] The invention relates to the technical field of waste gas recovery and reuse, in particular to a boiler tail gas recovery and utilization device. Background technique [0002] At present, coal-fired boilers are the main boilers used in the production of small and medium-sized enterprises and urban central heating in my country, most of which are chain boilers. The exhaust gas generated by the existing chain boilers is directly discharged through the exhaust output pipe, and the exhaust gas contains a large amount of nitrogen oxides. , pollute the air environment. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes an environment-friendly chain boiler tail gas recovery device which can significantly reduce the content of nitrogen oxides in the tail gas and significantly reduce emissions. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The en...
