Burning and waste heat power generation system for hazardous wastes

Abstract

Disclosed is a burning and waste heat power generation system for hazardous wastes. The burning and waste heat power generation system comprises a continuous feeding device, a flue gas purifying device, a power generation device, an online monitoring device, a bubbling bed incinerator and a waste heat boiler. The continuous feeding device is provided with a discharge port, the bubbling bed incinerator is provided with a feed port and an A flue gas outlet. The feed port of the bubbling bed incinerator is connected with the discharge port of the continuous feeding device; the waste heat boiler is provided with an A flue gas inlet and a B flue gas outlet, and the A flue gas outlet is connected with the A flue gas inlet of the waste heat boiler through a pipeline; the flue gas purifying device is provided with a B flue gas inlet, and the B flue gas outlet of the waste heat boiler is connected with the B flue gas inlet of the gas purifying device through a pipeline; and the power generation device is connected with the waste heat boiler through a main steam pipeline. According to the burning and waste heat power generation system for hazardous wastes, high-temperature flue gas produced by burning of deinking residues enters the waste heat boiler to absorb heat and produce superheated steam which is used for generating power, and accordingly, electric energy is added, and purposes of using flue gas waste heat for generating power and reducing environmental pollution are achieved.

Description

technical field [0001] The invention relates to the field of waste incineration and waste heat power generation systems, in particular to a hazardous waste incineration and waste heat power generation system capable of processing deinking slag from paper mills. Background technique [0002] Hazardous wastes refer to those listed in the national list of hazardous wastes or identified according to the identification standards and identification methods of hazardous wastes stipulated by the state, having one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity, and infectivity, and Solid wastes with the above hazardous characteristics are not excluded. Hazardous waste poses a significant threat to human health or the environment when improperly handled, stored, transported, handled and disposed of. [0003] Hazardous waste means solid waste or solid waste compounds which, by reason of their quantity, concentration and physical, chemical, ...

AI Technical Summary

Problems solved by technology

Disadvantages of using a rotary kiln incinerator to treat deinking slag are: high investment costs; care must be taken during operation, high maintenance costs for refractory bricks; deinking slag may quickly roll out of the kiln and cannot be completely incinerated; low thermal efficiency
