Glass body melting gasification furnace, gasification system and gasification method

Abstract

The invention discloses a glass body melting gasification furnace, a gasification system and a gasification method, and belongs to the technical field of solid waste and hazardous waste treatment. The gasification furnace comprises a shell, a slag pool is arranged at the bottom of the shell, a coal gas outlet is formed in the top of the shell, a gasification reaction chamber and a gas-slag separation section are arranged in a cavity of the shell, and the gasification reaction chamber comprises a main gasification reaction section, a rotational flow reaction section and a chilling section which are sequentially arranged from top to bottom, a burner channel is formed in the end face of the main gasification reaction section, and the main gasification reaction section is downwards communicated with the rotational flow reaction section in a spiral gradually-shrinking mode. Solid waste can be completely converted into pure glass, no waste water, waste gas and waste residues are discharged in the production process, coal gas and saturated steam with a certain heat value can be produced as byproducts, meanwhile, the height of a steel structure frame is reduced, cost is saved, and the device is small in size, simple in structure and wider in applicability.

Description

technical field [0001] The invention relates to the technical field of solid waste and hazardous waste treatment, and more particularly, to a glass melt gasifier, a gasification system and a gasification method. Background technique [0002] my country is a major resource consuming country in the world and a major producer of solid waste. At present, my country is facing the dual pressure of resource shortage and serious environmental pollution. At the same time, my country produces a large amount of solid waste every year, causing serious environmental and geological hazards, and occupying a large amount of land. The treatment of solid waste, especially hazardous waste, has always been the key to restricting the construction of ecological civilization in my country. [0003] The currently widely used technology is to incinerate solid waste, but incineration cannot solve the harmless problem at one time, and generally the incineration temperature is lower than 900 °C, and h...

Problems solved by technology

[0008] In view of the problem that the existing solid waste melting treatment technology can only achieve reduction and cannot be completely harmless, the present invention proposes a glass melting gasifier, gasification system and gasification method, which can completely transform solid waste Form a pure glass body, and there is no waste water, waste gas, and waste slag during the production process, and can by-produce coal gas and saturated steam with a certain calorific value. At the same time, the height of the steel structure frame can be reduced to save costs. wider
