Problems solved by technology

The state now encourages enterprises to dispose of self-produced hazardous waste. Most of the waste-producing enterprises have a small output (0.1-1t / d). The conventional rotary kiln incineration centralized disposal process is not suitable for enterprises to build their own hazardous waste disposal devices. Plasma gasification devices are already in place. The system is complicated, the process is complex, and the investment is large, the transportation radius of hazardous waste is large, it is difficult to realize skid-mounted movement, and it cannot adapt to the new mode of waste reduction at the source

Embodiment 1

[0022] Such as figure 1 As shown, the small-sized skid-mounted waste plasma gasification melting treatment device provided in this embodiment includes a horizontal plasma gasification furnace 3, a cold slag bucket 4, a spray quencher 6, a bag filter 7, an activated carbon box 8 and Induced fan 9.

[0023] The furnace body of the horizontal plasma gasification furnace 3 is arranged horizontally, the two sides of the side wall of the furnace body are respectively provided with a feed inlet and a flue gas outlet, the bottom of the furnace body is provided with a slag outlet, and the furnace body wall is provided with a Plasma torch5. Such as figure 2 As shown, the hearth of the horizontal plasma gasifier 3 is divided into a dry distillation zone, a redox zone, a slag zone, and a combustion zone. The dry distillation zone is located at the side of the feed inlet, and the redox zone is adjacent to the dry distillation zone Located in the area where the plasma torch 5 is located...

Embodiment 2

[0027] On the basis of embodiment 1, according to the moving direction of the raw material II entering the furnace, the raw material enters the dry distillation zone after entering the furnace from the feed port, and enters the redox zone after being dried and carbonized in the dry distillation zone. Oxidation-reduction reaction, after the oxidation-reduction reaction, it enters the combustion zone for full combustion; the inorganic matter in the raw material is melted into a liquid state and flows out from the slag outlet, and the organic matter in the raw material is dry-distilled, pyrolyzed, and oxidized to form carbon dioxide and The high-temperature flue gas of water vapor; the flue gas outlet is connected to the spray quencher 6 and the bag filter 7 to purify the high-temperature flue gas, and the purified flue gas III is discharged again.

Embodiment 3

[0029] On the basis of Embodiment 1 or 2, the feed port of the horizontal plasma gasifier 3 is connected with a funnel-shaped feed bin 1, and a push feeder 2 is arranged between the feed bin 1 and the feed port, The push feeder 2 pushes the raw material through the feed push rod.

Abstract

The invention provides a small skid-mounted waste plasma gasification melting treatment device. The device comprises a horizontal plasma gasification furnace, a slag cooling hopper, a spray quench cooler, a bag-type dust collector, an activated carbon box, and an induced draft fan; the gasification furnace is horizontally arranged; a dry distillation area, an oxidation-reduction area, a slag areaand a combustion area are arranged in a hearth of the gasification furnace; a feed port and a flue gas outlet are respectively formed in two sides of a furnace body; a slag discharge port is formed inthe bottom of the furnace body; a plasma torch is arranged on the wall surface of the furnace body; the bottom of the slag outlet is connected with the slag cooling hopper; the flue gas outlet end isconnected with the spray quench cooler; the outlet end of the spray quench cooler is connected with the bag-type dust collector; a gas outlet of the bag-type dust collector is connected with the activated carbon box; and the activated carbon box is connected with the induced draft fan. According to the small skid-mounted waste plasma gasification melting treatment device, the gasification and combustion integrated horizontal plasma melting furnace is adopted, the number of devices is small, the process is simple, skid-mounted arrangement is met, the device is suitable for source reduction andharmless treatment of solid waste of most waste production enterprises, the risk in the hazardous waste storage and transportation process can be greatly reduced, and automatic operation is easy to achieve.

Description

technical field [0001] The invention relates to the technical field of melting furnaces for treating solid waste, in particular to a small skid-mounted waste plasma gasification melting treatment device. Background technique [0002] Plasma melting treatment technology has the advantages of good solid hazardous waste reduction effect (high slag density), low secondary emissions (dioxin precursors are completely decomposed), high thermal efficiency, and the treated residue does not need secondary landfill, etc. , is internationally recognized as the most advanced and thorough technology for the harmless disposal of various types of waste. It has been widely used in western developed countries, and some cities use plasma high-temperature gasification devices as a way to deal with public health emergencies in modern large cities. The key and supporting equipment is in the technology demonstration stage in China and has not yet been applied on a large scale. Although the operat...
