Description
Technical Field
The invention relates to the field of environmental protection of chemical flue gas incinerators, in particular to a cooler of a hazardous waste incinerator.
Background
The traditional vertical rapid cooler has two types, one is designed by adopting lining casting materials and has a supporting type heating surface structure, and the high-temperature area of a supporting beam of the structure needs to adopt 1Cr20Ni14Si2 or more materials, so that the large-scale is limited; and the other is that the peripheral walls are wrapped with wall film type walls, and a heating surface structure is suspended, so that the structure or the high-temperature smoke velocity is too high to cause abrasion, or the medium-temperature smoke velocity is too low to accumulate ash, so that the smoke velocity in the whole process can not be uniformly 9-14m/s, and the cooling speed is slow, so that the synthesis of dioxin is easily caused in the process of reducing the smoke temperature of the smoke from 500 ℃ to 200 ℃.
Hazardous waste contains harmful substances such as dioxin, combustible substances, heavy metals and the like, and incineration is a means for reduction and harmlessness. The hazardous waste multi-pollutant integrated collaborative incineration treatment technology of my department can synchronously solve the integrated collaborative treatment overall process of desulfurization, denitration, dust removal, dioxin removal, gas removal waste, liquid removal waste, solid removal waste and heavy metal removal. The ash and slag discharged at high temperature can be used as solid waste after being detected to be qualified, such as being used as an additive of cement. The hot flue gas after high-temperature treatment generates saturated or superheated steam with high added value. The vertical rapid cooler is arranged as a device for absorbing the heat of the flue gas.
The flow direction of the flue gas of the traditional vertical-type rapid cooler is from top to bottom.
The upper part of a horizontal evaporation convection tube bundle of a traditional vertical rapid cooler adopts an inclined upward structure, and the inclined upward structure causes uneven flow field on the windward side of smoke, generates local abrasion and then explodes tubes.
The traditional rapid cooler adopts a light pipe economizer coiled pipe, so that the whole equipment is overhigh, the whole process investment is huge, the smoke speed at a low-temperature section is not 9m/s, and the dust deposition is serious.
The traditional SCR equipment flue adopts an external flue, occupies a large area, has uneven flue gas flow field and has huge investment.
In conclusion, the problem that the existing vertical rapid cooler is low in cooling speed, so that dioxin is easily synthesized, and the environment is damaged is solved.
