Gasification system of garbage and organic waste and device thereof

Abstract

The invention discloses a gasification system of garbage and organic waste and a device thereof, and relates to a garbage treatment device. The gasification system mainly consists of a blast drier, a gas phase circulation gasification furnace, a dusting / purification device, a compressor, a gas receiver and connection pipelines, wherein, the gasification furnace is equipped with a baking zone, a pyrolysis zone, a first gasification zone, a second gasification zone, a burnout zone and a heat storage chamber, a recirculating blower and a recirculating wind pipeline form a gas phase circulation loop outside the furnace. In the system, a discharge port of the blast drier is connected to a feed inlet of the gasification furnace, a synthesis gas output interface of the gasification furnace is connected to the dusting / purification device by an induced draft fan, the dusting / purification device is connected to the compressor, and the compressor is connected to the gas receiver. The system utilizes a technical measure of arranging the heat storage chamber in a gas phase circulation gasification furnace to enhance gasification rate and quality of refuse fuel and decompose dioxin with severe toxicity and eliminate coke tar, convert garbage and organic waste into secondary clean energy which comprises producer city coal gas, hydrogen, methanol and dimethyl ether liquefied gas.

Description

Technical field [0001] The invention relates to garbage and organic waste treatment equipment, in particular to garbage gasification equipment. Background technique [0002] At present, the energy shortage and the environmental protection situation are grim. With the development of my country's national economy and the continuous expansion of urban scale, garbage is increasing rapidly, and its content of harmful components is getting higher and higher. If it is not handled properly, it will pollute the environment and threaten people's health. This will not only restrict The progress of the society also affects the sustainable development of the national economy. At present, China's domestic waste treatment mainly includes sanitary landfill technology, composting (biochemical) technology and incineration technology. Most areas use sanitary landfill method to deal with domestic waste, which not only takes up a lot of land, wastes resources, but also easily pollutes land and ...

AI Technical Summary

Problems solved by technology

Since domestic waste is characterized by high water content, low calorific value, and high chlorine content, it is easy to generate highly toxic dioxins during incineration. The synthetic gas converted by conventional equipment has low calorific value and the quality cannot meet the application requirements. , therefore, there has been no commercial application report on converting domestic waste into secondary clean energy
