Embodiment Construction
[0029] The present invention uses a kind of waste gas treatment equipment, but the thermal decomposition and combustion of the heat treatment equipment in the prior art takes a long time, and the utilization rate of the heat source is low; the combustion chamber undergoes frequent cold and heat changes, the refractory device is frequently replaced, and the heat energy recovery is inconvenient. The supporting facilities required by the device have extremely high technical requirements, and are suitable for the treatment of hazardous wastes with high calorific value, loose shapes and uncomplicated components. The pyrolysis treatment effect on semi-fluid and large solid hazardous wastes is poor. The versatility of exhaust gas recovery is poor. Below through embodiment, in conjunction with accompanying drawing, this scheme is described further in detail.
[0030] Such as figure 1 As shown, it includes a combustion chamber, a heating device 1 connected to the combustion chamber, a...

The invention discloses waste gas treatment equipment, and belongs to the technical field of waste gas treatment.The waste gas treatment equipment is characterized in that the temperature of waste gas is further reduced through a quenching device, in order to prevent polluted waste gas from entering the atmosphere and waste gas in heating equipment from entering a denitration device, a urea solution is atomized through a spray gun, and the urea solution is atomized; waste gas and urea raw materials are mixed for a certain time, under the condition of gaseous oxygen in the denitration device, the utilization rate of the waste gas is increased, the waste gas enters a quench tower along with a pipeline to rapidly reduce the temperature of the waste gas, gasification is completed in the downward movement period of mixing of the waste gas and water vapor, meanwhile, an adjusting valve is arranged, the water supply amount is accurately adjusted, and the gasification efficiency is improved. Water mist is directly and fully mixed with waste gas, heat exchange is carried out, the adjusting mode is more convenient, and meanwhile, the heater at the bottom of the quench tower avoids dewing of settled ash.
Description
technical field [0001] The invention relates to waste gas treatment equipment, in particular to waste gas treatment equipment. Background technique [0002] Over the years, with the rapid development of my country's chemical, medical, pharmaceutical and other industries, the living standards and quality of the people have been greatly improved. However, at the same time, the hazardous waste generated in the production process of the pharmaceutical industry, medical industry and chemical industry has also increased sharply, resulting in increasingly prominent contradictions in the disposal of hazardous waste. Because there are many kinds of pollutants mixed with each other in hazardous waste, and some hazardous waste is even flammable and explosive, which is harmful to corrosion and infection. These hazards accumulate year by year, resulting in long-term shelving of hazardous waste, and the hazard exists for a long time; most hazardous waste contains heavy metal elements, wh...
