Boiler tail gas treatment device

Abstract

The invention discloses a boiler tail gas treatment device, and relates to the field of environmental protection equipment. The device comprises a pressure fan, a combustion chamber and a heating chamber; a separation box is arranged in the combustion chamber, an air outlet end of the pressure fan communicates with the separation box through an air pipe, the separation box communicates with the heating chamber through a gas guide pipe, and a water storage tank is arranged in the heating chamber; the separation box is formed by combining an upper shell and a lower shell, and the air pipe is connected with the upper shell; the upper shell is cylindrical, and the pipe opening of the air pipe is arranged in the tangential direction of the upper shell; the lower shell is in an inverted conicalshape, and a separation port is formed in the bottom of the lower shell; and an igniter is arranged at the position, corresponding to a separation port, in the bottom of the inner cavity of the combustion chamber. According to the device, fuel particles which are not fully combusted in the tail gas of the boiler can be separated out, the fuel particles are ignited to generate heat, and the heat ofthe part is integrated with the heat contained in the tail gas to act on the heating of the water storage tank, so that waste of resources is avoided, and the effects of saving energy and environmental protection are achieved.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a boiler tail gas treatment device. Background technique [0002] A boiler is a common infrastructure in the metallurgical industry. It is an equipment that uses fuel combustion to obtain energy. It will produce a certain amount of exhaust gas during operation. If these exhaust gases are not treated in time, they will pollute the environment. [0003] At present, most of the treatment devices for boiler exhaust gas only focus on removing harmful substances in it, but do not make full use of some incompletely burned fuel particles contained in the exhaust gas, which will easily lead to waste of energy, which is not in line with today's green environment. The theme of environmental development. Contents of the invention [0004] The object of the present invention is to provide a boiler tail gas treatment device to solve the above problems. [0005] To achieve ...
