Embodiment Construction

[0021] Such as figure 1 , Hazardous and medical waste incineration flue gas comprehensive absorption deacidification system, including quench tower 1, sodium bicarbonate powder injection tower 2, activated carbon powder injection tower 3, flue reactor 4, bag filter 5, pickling tower 6. Base washing tower 7, flue gas bypass 8, heat exchanger 9, quenching water tower 10, lye preparation tower 11, fly ash storage and transportation tower 12.

[0022] The high-temperature flue gas produced by the incineration of hazardous waste is purified and treated by the quench tower 1, the flue reactor 4, the bag filter 5, the pickling tower 6, the base washing tower 7, and the heat exchanger 9, and is drawn out by the induced draft fan and passed through the chimney. emitted into the atmosphere. Spray cooling medium into the quench tower 1 to make the flue gas cross the dangerous temperature area at the fastest speed. The specific process requirement is that the high-temperature flue gas q...

Abstract

The invention discloses a comprehensive absorption and deacidification system for dangerous and medical waste incineration flue gas. The system comprises a quenching tower, a sodium hydrogen carbonate powder spraying tower, an activated carbon powder spraying tower, a flue reactor, a cloth bag dust collector, an acid pickling tower, a base washing tower, a flue gas bypass, a heat exchanger, a quenching water tower, an alkali liquor preparation tower and a fly ash storage and transportation tower. The adaptive temperature range of the system is wide, the system can adapt to high-temperature flue gas with the temperature of 200-900 DEG C, and the process requirement on incineration equipment is not severe; the deacidification efficiency is high, the discharging index can be stably guaranteed and is superior to the GB18484-2001 standard; no sewage treatment equipment is needed in the production process, and zero sewage discharging is realized.

Description

[0001] technical field [0002] The invention relates to a tail gas purification process system applied in the field of environmental protection, in particular to a process system for processing and purifying flue gas from projects such as hazardous waste and medical waste incineration. Background technique [0003] Hazardous waste refers to waste that is included in the national list of hazardous waste or that is determined to have hazardous characteristics according to the national hazardous waste identification standards and identification methods. Mainly include: 1. Those with one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity or infectivity; 3. Medical waste belongs to hazardous waste. However, there are special regulations, which will be separately formulated and promulgated by the "Medical Waste Classification Catalog" according to the "Medical Waste Management Regulations". [0004] Hazardous waste has various sources an...
