Garbage high-temperature gasification auxiliary device

Abstract

The invention discloses a garbage high-temperature gasification auxiliary device. The device comprises a furnace body; a stirring main shaft penetrates through the top of the inner cavity of the furnace body; the stirring main shaft is a middle gas storage cavity which is through along a vertical direction; the top of the stirring main shaft is fixedly sleeved with a first belt pulley; a garbage inlet and a motor are respectively arranged on two sides of the top of the furnace body; an output shaft of the motor is fixedly sleeved with a second belt pulley; a plurality of first crushing bladesare fixed at the lower end of the stirring main shaft; second crushing blades are fixed to the inner wall of the furnace body; an air supply pipeline is arranged in an inner cavity of the stirring main shaft in a penetrating mode; an air distribution box is fixedly connected to the bottom of the air supply pipeline; an air storage cavity is formed in the inner side of the air distribution box; anda plurality of first air nozzles and second air nozzles are evenly installed on the outer surface of the air distribution box. According to the garbage high-temperature gasification auxiliary device,gas can be in uniform contact with scattered materials, the contact effect is better, so that the gasification quality is greatly improved; the furnace body is cooled through the gas, potential safety hazards are eradicated, the cost is reduced, and the universality is high.

Description

technical field [0001] The invention relates to the technical field of garbage treatment equipment, in particular to a high-temperature gasification auxiliary device for garbage. Background technique [0002] At present, the domestic garbage produced by people in daily life has become a key source of environmental pollution, and the treatment of domestic garbage has become an urgent problem to be solved; the existing domestic garbage treatment technologies mainly include composting, landfill, incineration and pyrolysis gasification, thermal Degasification is an advanced technology for domestic waste treatment. While realizing the harmless treatment of domestic waste and avoiding dioxin emissions, it can also extract energy and realize the resource utilization of domestic waste, which can effectively save energy and reduce waste incineration. Environmental issues such as dioxin emissions. [0003] General waste incineration equipment has a high content of pollutants in the f...

Problems solved by technology

[0003] General waste incineration equipment has a high content of pollutants in the flue gas during operation, and cannot effectively eliminate carcinogenic and highly toxic dioxins and furfur. The biomass waste gasifier converts waste and biomass into clean waste through gasification. Secondary energy can not only solve the problem of environmental pollution, but also reduce the dependence on oil and coal resources

The furnace body consists of a pretreatment bin, an oxidation incineration bin, a reduction cracking bin, and a carbonization activation bin in order from top to bottom. Treatment, gas and activated carbon are obtained in the carbonization activation bin to realize graded gasification, and biomass pyrolysis, oxidative incineration, reduction cracking and carbonization activation are relatively separated. However, in actual use, biomass waste agglomerates and falls. Single-pipe addition, which leads to incomplete contact between biomass waste and hydrogen

[0004] After high-temperature pyrolysis and gasification of domestic waste, the gasification layer needs to be cooled. However, half of the current use is water pipe circulating water cooling, water enters from the lower side and water exits from the upper side, and the circulating water pipe is inside the gasification layer. It takes the heat away, and then, the current circulating water pipes are generally bent and connected, with many water pipe joints, and the water pipe joints are aging due to long-term use, resulting in water leakage, which has brought a major safety hazard to garbage gasification problems, and affect the gasification effect
