Fluidized bed co-processing solid-liquid polymorphic hazardous waste incineration system and method thereof

Abstract

The invention discloses an incinerating system and method of disposing solid-liquid multi-phase hazardous waste mutually for a fluidized bed. The incinerating system comprises a fluidized bed incinerating device body, a liquid hazardous waste feeding system, a solid hazardous waste feeding system, a waste heat utilizing system and a tail gas treatment system. According to the incinerating system and method, solid-liquid multi-phase waste enters the fluidized bed incinerating device body respectively through the liquid hazardous waste feeding system and the solid hazardous waste feeding system to be incinerated, and waste heat utilization and clean gas clean-up processing are carried out on smoke through the waste heat utilizing system and the tail gas treatment system. The incinerating system and method are a whole system which composed of an incinerating device, waste heat utilization and tail gas processing, and are suitable to the reduction of multi-phase hazardous waste and resource utilization. Therefore, fluidized bed device incineration of different feed materials aiming at hazardous waste of different physical states is achieved, the technical problem that one feeding device carries out hazardous waste feeding material limitation of different states is solved, and meanwhile the resource reusing and the detoxifying treatment of the hazardous waste are achieved.

Description

technical field [0001] The invention relates to a fluidized bed disposal and resource reuse technology of hazardous waste, in particular to a fluidized bed co-processing solid-liquid polymorphic hazardous waste incineration system and a method thereof. Background technique [0002] According to the statistics of the Ministry of Environmental Protection, in 2009, the national hazardous waste production volume was 14.298 million tons, of which the comprehensive utilization (including the use of storage in previous years), storage volume, and disposal volume were 8.3 million tons, 2.19 million tons, and 4.28 million tons, respectively. However, judging from the industrial solid waste declaration and registration data and the ratio of foreign hazardous waste to industrial solid waste, the amount of hazardous waste generated in my country should be between 40 and 60 million tons, which is 3 to 4 times the published statistical data. With the rapid growth of my country's economy, t...

Problems solved by technology

[0004] However, the current fluidized bed incinerator has the weakness that it can only handle solid hazardous waste such as sludge or garbage, and is not suitable for the disposal capacity of a large amount of liquid and solid hazardous waste. It is necessary for the fluidized bed combustion device of hazardous waste in various states to be able to meet the pollutant discharge standards of hazardous waste devices
