Embodiment Construction

[0020] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0021] according to figure 1 , 2 As shown: this embodiment provides a waste gas incineration recovery furnace, including a waste gas nozzle 5, a boiler shell 6, an insulating material layer 7, a burner 9, a convection heating surface furnace tube 2 inside the boiler shell 6, and a radiation heating surface Furnace tube 3;

[0022] The boiler shell 6 is a circular cylinder with a horizontal installation structure. The boiler shell 6 is rolled from a steel plate made of 20# (GB713) "steel plate for boiler and pressure vessel". The bottom of the boiler shell 6 is installed There is a support 12 welded and fixed to it. Two sets of supports 12 are arranged near the front end and the rear end to support the boiler shell...

Abstract

The invention relates to an exhaust gas incineration recovery furnace. The exhaust gas incineration recovery furnace comprises a plurality of exhaust gas spray openings, a furnace shell, a heat insulation material layer, a burner, a convection heating surface furnace pipe and a radiation heating furnace pipe, wherein the convection heating surface furnace pipe and the radiation heating surface furnace pipe are arranged in the furnace shell. An opening in one end of the furnace shell is a smoke outlet, and an opening in the other end of the boiler shell is internally provided with the burner. The convection heating surface furnace pipe and the radiation heating furnace pipe are of spiral structures distributed on the inner wall of the boiler shell in parallel. The convection heating surfacefurnace pipe is installed on the side of close to the smoke outlet, and the radiation heating surface furnace pipe is installed on the side close to the burner. The exhaust gas spray openings are distributed on the surface of the boiler shell in the radial direction. The exhaust gas incineration recovery furnace is reasonable in structural design, in the application process, due to the fact thata heat absorbing heating surface composed of the convection heating surface furnace pipe and the radiation heating surface furnace pipe is arranged inside the exhaust gas incineration recovery furnace, the outer surface of the incineration furnace is far lower than a standard requirement, the thickness of the insulation material layer is reduced to the minimum, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a waste gas incineration recovery furnace. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially chemical plants, iron and steel plants, pharmaceutical plants, coking plants, oil refineries, etc., as well as the production of domestic waste gas from human life, the exhaust gas has a strong smell, which seriously pollutes the environment and affects human health. [0003] Industrial waste gas emitted by various production enterprises is an important source of air pollutants. If a large amount of industrial waste gas is discharged into the atmosphere without treatment and reaches the standard, it will inevitably reduce the quality of the atmospheric environment, bring serious harm to human health, and cause huge losses to the national economy. Toxic and harmful substances in indu...
