Embodiment

[0025] like figure 1 The embodiment of the present invention provides a combination process for handling heat -solving exhaust gas, including the following steps:

[0026] S1. Thermal dissolving gas first enters the dust filter, filtering most of the dust and caramel, and the filtering material uses multi -layer porous fiber cotton and other materials to replace it regularly;

[0027] S2. After the preliminary filtering gas is sent to the cooling system, the cooler uses the principle of washing and cooling, an external air -cooler, and the cooling gas is used to cool the heat. There is a filler layer inside the cooler. Materials (such as Lasi Ring, Balt Ring, etc.), increase the contact area of ​​gas and cooling water, and improve the cooling efficiency. The two -stage coolers are connected in series. The remaining dust and tar are removed simultaneously, used to use water circulation for washing, and regularly discharged to the sewage receiving system (such as municipal sewage pi...

Abstract

The invention provides a combined process for treating pyrolysis waste gas, and relates to the field of pyrolysis waste gas treatment. The method comprises the following steps: S1, pyrolysis gas firstly enters an oil dust filter to filter out most of dust and tar, S2, gas subjected to preliminary filtration is fed into a cooling system, coolers adopt a washing cooling principle, an external air cooler is arranged, circulating water is used for cooling hot gas, two stages of coolers are connected in series, the temperature of the gas subjected to two-stage cooling is reduced to 60 DEG C or below, and the gas is cooled to the temperature of 60 DEG C or below; and S3, the cooled and dedusted gas is fed into a steam-water separator, most of water vapor is removed, and the dried gas enters a plasma reactor. The comprehensive energy consumption is low, no secondary pollution is generated, matched equipment can be made into an integrated structure, the occupied area is small, the layout is compact, the one-time investment and operation cost is low, the application occasion is wide, the environmental hidden danger of pyrolysis flue gas is relieved by putting pyrolysis flue gas purification equipment into use, and popularization of a pyrolysis method in the field of household garbage treatment is promoted.

Description

Technical field [0001] The invention involves the field of home thermal solution exhaust gas treatment, which is specifically for a combination process for handling heat -solving exhaust gas. Background technique [0002] At present, the treatment of organic waste treatment in cities and towns and towns is more common in hygiene landfill, compost, incineration and thermal solution. Compared with other processes, thermal solution is produced in the degree of reduction, pollution gases (such as two evil heroes, 呋 目前, etc.), and the occurrence. It has a great advantage, and the proportion of application in the project has gradually expanded, and it is also an important development direction for urban organic waste treatment in the future. Thermal solution technology refers to high temperature and heat decomposition of urban domestic garbage in anaerobic or hypoxic environment. Using complex heat absorption and heat -deducting reactions, organic matter in biomass, thermal chemical co...
