Problems solved by technology

[0008] The above two stages are hotbeds for the formation of dioxins. Both incinerators and gasifiers at home and abroad are inevitably faced with this problem, but there is no device and process that can better solve this problem.

Embodiment

[0042] A. The gas production capacity of this gasifier is 600m 3 / h. The combustible garbage is fed into the distributor 2 from the feed hopper 15 above the gasifier. The distributor 2 is conical and connected to the end cover 1 of the upper furnace body with a flange. 4 cloth straight boards and 4 slanted boards for the cloth, uniformly distribute the cloth 360 degrees into the furnace;

[0043] The furnace body 3 adopts an inverted cone structure to ensure that the garbage and other materials have a sufficiently high gasification reaction intensity when they move downward with the gasification process. The radiation high temperature refractory layer in the furnace ensures the life span and high temperature resistance of the furnace itself.

[0044] B. Send high-temperature air at 100°C through nozzles 13 arranged around the redox zone of the furnace to achieve uniform air distribution in the redox zone; the nozzle 13 is at 45 degrees to the inner wall of the furnace, and i...

Abstract

The present invention relates to a combustible rubbish gasification gas-making device for preventing dioxin from being produced, comprising a gasifying furnace body, the upper part of which is provided with a feeding bucket; the upper part inside the furnace body is provided with a material distributor; the lower part inside the furnace body is provided with a furnace grate and an ash remover; the lateral wall of the furnace body is provide with a nozzle; the underside outside the furnace body is connected with a fuel gas inlet and a fuel gas outlet; the nozzle is tangent towards and forms an angle of 30 to 60 degrees with the furnace body downwards; the fuel gas outlet is provided with a fuel gas quencher dioxin separator. The present invention also provides a combustible rubbish gasification gas-making technology for preventing the dioxin form being produced. The present invention starts with the structure of the gasifying furnace body, the burning theory and a fuel gas quencher system to completely control the reaction temperature, prolong the fuel gas stopping time at a high temperature area and at the same time realize the rapid quencher and cooling of the fuel gas, which radically destroys the mechanism and the condition for generating the dioxin and avoids the produce of the dioxin.

Description

technical field [0001] The invention relates to a solid combustible waste gasification gasification device and process mainly based on urban combustible waste, specifically a solid combustible waste gasification gasification device and process that can prevent the generation of dioxins, suitable for Raw materials include urban combustible waste, agricultural and forestry waste, etc. Background technique [0002] With the development of China's social economy, about 2 / 3 of the cities have fallen into the plight of garbage siege. The annual output of "urban waste" in my country alone is nearly 150 million tons, and most of these urban wastes are piled in the open air. It not only affects the urban landscape, but also pollutes the atmosphere, water and soil that are vital to our lives, and poses a threat to the health of urban residents. Garbage has become a thorny issue in urban development. At present, besides open-air stacking, sanitary landfill is the method for dealing w...
