Embodiment Construction

[0019] in the attached figure 1 The medium waste gas incineration heat exchanger is mainly composed of an incinerator 1 and a waste gas heat exchanger, and the middle is connected by a variable-diameter air pipe 3. The solvent-rich waste gas is sent to the heat exchanger pipeline from the waste gas inlet 9 by the power of the circulating fan 8 through the waste gas. 7 enters the exhaust gas heat exchanger, and after heat exchange, the exhaust gas is sent to the incinerator pipeline 2 and sent to the incinerator 1.

[0020] in the attached figure 2 , attached image 3 There is a burner 17 at the front end of the incinerator 1 of the waste gas incineration heat exchange furnace. After being ignited by the burner, the air and fuel are burned in the combustion tube 12. The solvent-rich waste gas after heat exchange enters the incinerator through the waste gas inlet, and the high-pressure waste gas hits The combustion tube 12 enters the furnace body through the diffuser plate 24...

Abstract

The invention provides a waste gas incineration recuperative furnace, which aims to solve the problems of short incineration cracking time, incomplete cracking, easy burnout and difficult maintenance of a recuperator in the incinerator, and the like existing in the prior waste gas incinerator. The proposal comprises that a structure that the recuperator is arranged outside the incinerator and communicated by a diameter changing air pipe is adopted, and the wall of a furnace body on the back part of an air distribution plate is wave-shaped, so that the thermal expansion of the furnace body is avoided; a bottom frame is provided with rollers, on which the incinerator body can be freely flexed; due to the adoption of the structure, the burnout of the recuperator due to high-temperature flamewhen the waste gas is burnt is avoided, and the expansion of the furnace body caused by the thermal expansion of the furnace body can also be eliminated; moreover, the furnace has the advantages of simple structure and easy processing and assembly.

Description

technical field [0001] The invention belongs to the technical field of environmental protection facilities, and relates to an incineration heat exchange furnace, in particular to a waste gas incineration heat exchange furnace. Background technique [0002] The color-coated board production line generally adopts the heating and drying method after applying liquid paint. The solvent is heated and evaporated by the heat in the curing furnace, and the strip is heated to a predetermined temperature to cure the coating. This process consumes a lot of energy. At present, in order to meet environmental protection standards, the domestic color-coated board production line generally extracts the exhaust gas in the furnace and heats it to the temperature of the exhaust gas cracking point (733°C) for cracking and incineration. Most of the solvents in the exhaust gas containing toxic gases are cracked, burned, and released. A large amount of heat energy is produced, and most of the oxyge...
