An organic solid waste pyrolysis gasifier and steam generation system

Abstract

The invention belongs to the field of organic solid waste reuse and hot water steam generation, and in particular relates to an organic solid waste pyrolysis gasifier and a steam generation system. The organic solid waste pyrolysis gasification furnace includes a long cylindrical furnace body, a heat exchanger is arranged in the long cylindrical furnace body, the side wall of the long cylindrical furnace body and the side wall of the heat exchanger are separated to form a gas layer, The top wall of the long cylindrical furnace body is provided with a feeding port for adding organic solid waste materials into the heat exchanger cylinder, and an openable and closable sealing cover is provided at the feeding port, and a connecting gas layer is provided on the long cylindrical furnace body. gas pipe. The steam generation system includes the above-mentioned organic solid waste pyrolysis gasifier, a gas purifier, a first exhaust fan, and a steam boiler. The pyrolysis gasification furnace has a built-in heat exchanger, which can not only protect the furnace of the pyrolysis gasification furnace, but also reduce the loss of heat energy. The hot water generated is injected into the steam boiler, and the gas produced can be used to heat the steam boiler after purification. Preheated hot water, reasonable design, high utilization rate of organic solid waste.

Description

technical field [0001] The invention belongs to the field of organic solid waste reuse and hot water steam generation, and in particular relates to an organic solid waste pyrolysis gasifier and a steam generation system. Background technique [0002] In recent years, my country's urbanization process has accelerated, and the number and scale of cities have continued to expand. However, due to the serious lag in environmental protection infrastructure, the pollution of urban ecological environment by urban waste has become increasingly serious. my country produces nearly 150 million tons of municipal waste every year, and it is still growing at an average annual rate of about 10%. At present, landfill and incineration are still the main methods of urban waste treatment in my country, which occupy a large amount of land, causing secondary pollution such as seepage water and dioxins; especially in small cities with weak economic strength, open-air piles of waste in the suburbs ...

Problems solved by technology

However, most of the existing solid waste pyrolysis gasifiers use fireproof bricks to protect the inner wall of the furnace from high temperature damage. However, the water vapor generated by the pyrolysis and gasification of organic solid waste will cause weathering and peeling of the fireproof bricks, and the fireproof bricks have to be replaced frequently. bricks, causing troubles to equipment repair and maintenance; at the same time, it also caused a waste of heat energy

Therefore, the energy utilization efficiency of the traditional pyrolysis gasifier is low, and most of the heat energy generated during the pyrolysis process is lost in the form of radiant heat.
