Embodiment 1

[0046] refer to figure 1 As shown, this embodiment provides a garbage cracking gasification device, including: a furnace body 1, a feeding device 2, a slag removal device 3, a wind pressure system 4, a temperature sensor 5, a material distribution mechanism 6, a base 7 and a column 8 .

[0047] Furnace body 1 ; the furnace wall of the furnace body 1 includes an outer cylinder 11 and an inner cylinder 12 . Both the outer cylinder 11 and the inner cylinder 12 are welded with steel plates, and the inside is smooth. A transverse partition is also provided between the outer cylinder 11 and the inner cylinder 12 to divide the space between the outer cylinder 11 and the inner cylinder 12 into upper and lower water jackets. Both the upper and lower water jackets are filled with cooling water, and water inlet pipes and water outlet pipes (not shown in the figure) are provided in the upper and lower water jackets. The inner wall of the conventional garbage cracking gasifier is cut wi...

Embodiment 2

[0060] This embodiment provides a control method for a control system of a garbage cracking and gasification device. The control system of the garbage cracking and gasification device includes: a feeding control unit, a furnace temperature control unit, a wind pressure control unit, and a slag removal control unit; The method includes the following steps:

[0061] S1, obtain the garbage block to be fed, and put it into the feeding device 2;

[0062] Specifically, the garbage block in step S1 is a compressed block after dehydration, and the length of the garbage block is 4-6 cm, preferably 5 cm; the width is 3-5 cm, preferably 4 cm; the height is 3-6 cm. 5cm, preferably 4cm. After the pre-treatment, the garbage block has been dehydrated and compressed into a block, which is beneficial to the controllability of the feeding of the garbage and the uniformity of the burning, cracking and gasification of the garbage.

[0063] S2, start the feeding control unit, put the garbage blo...

Abstract

The invention provides a garbage cracking gasification device. The garbage cracking gasification device comprises: a furnace body; a feeding device which is used for feeding materials into the furnace body; a slag removal device which comprises a slag removal grate bar arranged in the furnace body, and a slag storage tank and a transmission system which are arranged outside the furnace body; an air pressure system, wherein an air inlet pipe of the air pressure system supplies air into the furnace body from an air outlet in the top end of the slag removal furnace bar; a plurality of temperature sensors which are arranged in the furnace through the holes in the furnace wall of the furnace body and are used for detecting the reaction temperature of each gasification layer in the furnace body; and a control system which is used for acquiring the temperature in the furnace measured by the temperature sensor, and regulating and controlling the air inlet amount of the air pressure system according to the temperature in the furnace, so that the feeding amount of the feeding device is controlled, and the slag removal device is controlled to remove slag. The garbage cracking gasification device provided by the invention is convenient for gasification treatment of household garbage which is not sorted, the reaction process of the garbage is controlled in a programmed manner, and the garbage combustion yield is effectively improved.

Description

technical field [0001] The invention relates to the field of garbage treatment equipment, in particular to a garbage cracking gasification device. Background technique [0002] With the continuous improvement of people's living standards and consumption power, more and more domestic waste is produced. At present, the disposal methods of garbage mainly include landfill, incineration, and pyrolysis and gasification of garbage to produce combustible gas for recycling. Landfilling will occupy land resources and affect the quality of groundwater. Incineration costs are high, pollute the air, waste resources, and are not conducive to sustainable development. The recycling of combustible gas produced by pyrolysis and gasification of garbage is a green and sustainable way, and it is also conducive to saving resources. [0003] At present, the pyrolysis gasification process of garbage is mainly carried out by garbage pyrolysis gasifier. General garbage pyrolysis gasification furn...
