Embodiment

[0017] like figure 1 As shown, this embodiment provides a heat storage type pyrolysis gasification device, which mainly includes a water vapor control system, a pyrolysis gasification furnace 2 and a heat storage system. The water vapor control system is connected with the heat storage system, and the heat storage system is arranged in the throat 13 of the pyrolysis gasification furnace 2 .

[0018] The pyrolysis gasification furnace 2 includes a material inlet 9, an air outlet 10, a throat 13, a fire grate 12, an ash chamber 6 and an insulation layer 1. The feed inlet 9 is arranged at the top of the furnace body, the gas outlet 10 is arranged on the right side of the top of the furnace body, the throat 13 is arranged at the lower part of the furnace of the pyrolysis gasification furnace 2, the grate 12 is arranged below the throat 13, and the ash chamber 6 is located at the bottom of the furnace. At the bottom of the body, the thermal insulation layer 1 is wrapped on the sur...

Abstract

The invention discloses a heat accumulating type pyrolysis gasification device, which comprises a water vapor control system, a pyrolysis gasification furnace and a heat accumulating system; the heatstorage system is arranged in a throat of the pyrolysis gasification furnace, so that the temperature of the pyrolysis gasification furnace is controlled through heat storage and release reaction; andthe water vapor control system is connected with the heat storage system and controls the heat storage and release reaction of the heat storage system. According to the invention, continuous and stable thermal conversion reaction of combustible solid waste can be realized; and the temperature in the pyrolysis gasification furnace is adjusted through heat storage and release of the heat storage material in the throat, so that the problem that the hearth temperature distribution time is not matched with the space in the thermal conversion process of an existing pyrolysis gasification furnace issolved, energy waste is reduced, and the pyrolysis gasification effect of combustible solid waste is improved.

Description

technical field [0001] The invention relates to combustible solid waste treatment equipment, in particular to a heat storage type pyrolysis gasification device. Background technique [0002] According to statistics, the annual volume of urban solid waste (hereinafter referred to as "urban solid waste") in China is about 228 million tons, and the annual growth rate is 8-10%. A large amount of urban solid waste not only pollutes the environment, but also endangers human health. . Urban solid waste contains a large amount of combustible solid waste such as agricultural and forestry waste, organic components in domestic garbage, and municipal sludge (hereinafter referred to as "combustible solid waste"), accounting for about 30% of urban solid waste, so combustible solid waste has The potential of resource utilization and energy utilization. Combustible solid waste has variable size, complex components, high moisture content, and many types of pollutants, which make it difficu...
