Embodiment Construction

[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0029] see figure 1 and figure 2

[0030] In a waste incineration treatment plant, a small waste incinerator 1 is provided. The tail gas discharge of the waste incinerator 1 is connected to a box 3 of a plasma catalytic oxidation purification device, and the other end of the box 3 is also connected to a tail gas Emissions from the chimney 2. The tail gas discharge place of the garbage incinerator 1 is connected to the box body 3 through the air guide pipe, the air guide pipe is connected to the box body 3 through the bell mouth, and the other end of the box body 3 is also connected to the chimney 2 through the bell mouth. The tail gas after garbage incineration is purified by the box and then discharged.

Abstract

The invention relates to a plasma-catalytic oxidation refuse burnt and cracked tail gas purification device comprising a set of plasma-catalytic oxidation and purification device arranged in the tail gas discharging position of a refuse burning furnace or a refuse cracking furnace. The plasma-catalytic oxidation and purification device is characterized in that a tank body of the plasma-catalytic oxidation and purification device is connected with an air outlet of the burning furnace or the cracking furnace through a pipeline and a reducer. Harmless tail gas treated by the purification device is discharged after achieving standards; the front stage in the tank body is provided with a discharge toothed plate and a dust connecting plate which form a plasma electric field, and two electrodes of the plasma electric field are connected with a strong-pulse plasma power supply; and the back stage in the tank body is provided with a catalyst assembly, an oxidant assembly and a catalytic oxidation device shell which form a catalytic oxidation device. The tail gas purification device has the obvious effect of purifying the burnt tail gas and fundamentally eliminates secondary pollution generated in the thermal treatment process of house refuses.

Description

technical field [0001] The patent of the present invention relates to the technical field of air pollution control, and specifically relates to a toxic and harmful tail gas purification device matched with domestic waste incineration or cracking furnace. Background technique [0002] With the rapid growth of China's economy and the continuous improvement of people's living consumption levels, the output of urban domestic waste has continued to increase, causing great damage to urban and rural environments and threatening human health and survival. [0003] At present, countries all over the world are studying the methods of domestic waste disposal: [0004] Generally, landfill method, composting method, incineration method, pyrolysis method, biological method, etc. are used. Among them, the incineration method and the cracking method are more in line with the sustainable development strategy. However, various toxic and harmful gases, especially dioxins and heavy metals, ar...
