Garbage pyrolysis furnace

Abstract

The invention provides a garbage pyrolysis furnace, which comprises an inner furnace body and an outer furnace body, wherein a pyrolysis chamber is formed in the inner furnace body, two ends of the pyrolysis chamber respectively extend outwards to form a material inlet cavity and a material outlet cavity, a material inlet is formed in the top of the material inlet cavity, a hydraulic pushing sealing device is arranged in the material inlet cavity, a water filtering assembly is arranged at the bottom of the material inlet cavity, a material outlet is formed in the bottom of the material outletcavity, the material outlet cavity is provided with a hydraulic sealing device, an oil gas collector is connected to the upper portion in the pyrolysis chamber, and is connected to a cooling device arranged outside the pyrolysis chamber through an oil gas outlet pipe, the cooling device is communicated to an oil-gas separator, the oil-gas separator is connected to a buffer tank, and the buffer tank is connected to a compression tank. According to the invention, the garbage pyrolysis furnace has a horizontal structure, and the two ends of the pyrolysis chamber are matched to operate in a hydraulic sealing mode, so that the complex sealing structure is simplified, the dewatering function can be synchronously achieved, the pyrolysis effect is remarkable, and the manufacturing cost is greatlyreduced.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment manufacturing, in particular to a garbage pyrolysis furnace. Background technique [0002] The incineration of waste is an important means of reducing and harmless treatment, but the existing pyrolysis waste treatment device can only heat the temperature in the furnace to 450 to 750 degrees Celsius, which will produce dioxins, Heavy metals and acid gases are likely to cause secondary pollution to the environment, and the existing incinerators cannot realize the self-combustion of garbage. Coal, oil, electricity, etc. are used as raw materials for heat production, and the heat consumption is large. The temperature can reach up to 850 degrees Celsius, and many harmful substances are likely to be produced during the incineration process, especially the highly toxic carcinogenic pollutant dioxin.

Problems solved by technology

[0002] The incineration of waste is an important means of reducing and harmless treatment, but the existing pyrolysis waste treatment device can only heat the temperature in the furnace to 450 to 750 degrees Celsius, which will produce dioxins, Heavy metals and acid gases are likely to cause secondary pollution to the environment, and the existing incinerators cannot realize the self-combustion of garbage. Coal, oil, electricity, etc. are used as raw materials for heat production, and the heat consumption is large. The maximum temperature reaches 850 degrees Celsius, and many harmful substances are likely to be produced during the incineration process, especially the highly toxic carcinogenic pollutant dioxin

[0003] All in all, the existing waste incineration and pyrolysis furnaces are still unable to deal with wastes such as household garbage with high water content, which requires labor-intensive screening and dehydration operations, and consumes a large amount of energy resources such as coal, oil, and electricity , the treatment temperature is low, it is easy to produce highly toxic pollutants, and the treatment cost of the flue gas is high, which cannot meet the needs of the existing organic waste treatment

[0004] The pyrolysis method is to use the thermal instability of the organic matter in the garbage to heat and distill it, so that the organic matter can be pyrolyzed and condensed to form various new gases, liquids and solids, from which fuel oil and combustible gas are extracted. During pyrolysis, the pyrolysis chamber needs to be sealed, and the sealing structure of the existing pyrolysis furnace is relatively complicated and the cost is high
