Problems solved by technology

[0002] The current garbage and sludge treatment methods in my country mostly use three methods: sanitary landfill, composting and incineration. These three existing methods have the disadvantages of polluting the environment, wasting land and consuming a lot of energy. Therefore, the development of new garbage and sludge Sludge treatment methods and processes are imperative

Embodiment Construction

[0030] Refer to attached Figures 1 to 4 As shown, the pyrolysis gasification furnace of the present invention includes a furnace body 1 , a combustion chamber 2 and a rapid cooling tube 3 .

[0031] The furnace body 1 is a sealable chamber with a feed inlet 11 on its upper part, a slag discharge port 12 and an exhaust port 13 on its lower part, and an air inlet for feeding auxiliary gas on the side wall of the furnace body 1. . The feeding port 11 is connected with the hydraulic closed continuous feeding system 6 . This body of heater 1 inside is provided with four-layer fire grate 15, then this fire grate 15 is divided into four combustion chambers by body of heater 15, and the body of heater side wall of each combustion chamber is all provided with air inlet, and organic waste is discharged from the upper part. The feed port 11 enters the uppermost combustion chamber after being sealed and fed through the hydraulic closed continuous feeding system 6, where the organic mat...

Abstract

The invention discloses a pyrolysis gasification furnace, which comprises a furnace body, a combustion chamber and a rapid cooling pipe. There is an air inlet on the side wall, and there are four layers of grates inside the furnace body. The grates on the grate are rotatable, and the distance between the grates on the lower layer is equal to or smaller than the distance between the grates on the upper layer; The entrance of the combustion chamber is connected with the exhaust port of the furnace body, an ignition device is arranged on the side wall of the entrance of the combustion chamber, the outlet of the combustion chamber is connected with the entrance of the rapid cooling pipe, and at least one gas distribution pipe is arranged on the rapid cooling pipe. In the present invention, by setting a closed furnace body with four layers of grates, the organic waste can be fully burned, and the furnace temperature can reach 1200°C, which is higher than that of the fluidized bed furnace and the grate furnace, avoiding the temperature range of 360°C to 360°C for the generation of dioxin 820°C, and using the principle of rapid cooling, the high-temperature gas is rapidly reduced to below 200°C, and the reduction of dioxins is controlled. The emission index of this gasifier is far better than the national standard.

Description

technical field [0001] The invention relates to the technical field of waste incineration treatment, in particular to a pyrolysis gasifier. Background technique [0002] The current garbage and sludge treatment methods in my country mostly use three methods: sanitary landfill, composting and incineration. These three existing methods have the disadvantages of polluting the environment, wasting land and consuming a lot of energy. Therefore, the development of new garbage and sludge Sludge treatment methods and processes are imperative. How to reduce the discharge of garbage and sludge, realize the harmlessness, reduction, and recycling of garbage and sludge, turn garbage and sludge into treasure, and realize the resource recycling of urban solid waste is a key issue in my country. An important topic in modern urban management. [0003] On the basis of the above background, the present invention creates a new pyrolysis gasifier, which can effectively reduce the emission of dio...
