Problems solved by technology

The disadvantage is that it destroys resources. Garbage contains about 70% of water. The water-containing organic matter consumes energy, and combustible garbage releases energy. During the incineration process, the energy consumed and the released energy are offset, and the remaining energy is little or negative. Therefore, there are requirements for the calorific value of garbage. Incineration will consume coal, oil and other combustion-supporting energy, wasting a lot of recyclable resources, and will form dioxins during incineration, which will easily cause air pollution

Embodiment 1

[0046] Such as figure 1As shown, a biomass gasification and medical waste incineration co-production system includes a gasification furnace 1, an incinerator 2, a combustion chamber 3, a pulverizer 4, a pneumatic rotating mechanism 5 and a steam boiler 6, and the gasification furnace The flue gas outlet of 1 is connected with the combustion chamber of incinerator 2, that is, the combustible gas produced by the gasification of biomass in gasifier 1 can enter the combustion chamber of incinerator 2 through the flue gas outlet. The combustible gas can also enter the combustion chamber 3, and the flue gas outlet of the incinerator 2 is connected with the flue gas inlet of the combustion chamber 3, that is, the flue gas generated after the medical waste is burned in the combustion chamber 3 can enter the combustion chamber through the flue gas outlet. In the chamber 3; the flue gas outlet of the combustion chamber 3 communicates with the flue gas inlet of the steam boiler 6, that i...

Embodiment 2

[0048] Such as figure 1 , figure 2 As shown, the present embodiment is a further improvement carried out on the basis of embodiment 1, which is specifically as follows:

[0049] The powder outlet of the pulverizer 4 is connected with the flue gas outlet of the gasification furnace 1, that is, the charcoal powder ground by the pulverizer 4 can also be sprayed into the incinerator 2 under the action of the combustible gas produced by the gasification furnace 1. In the combustion chamber, it can support the combustion of medical waste for incineration, reducing the consumption of combustion-supporting energy such as coal and oil.

Embodiment 3

[0051] Such as figure 1 , figure 2 As shown, the present embodiment is a further improvement carried out on the basis of embodiment 2, which is specifically as follows:

[0052] The pneumatic rotating mechanism 5 includes a cylinder 510, a main shaft 520, an impeller 530 and a nozzle 540. The impeller 530 is arranged in the inner chamber of the cylinder 510, the main shaft 520 is installed on the impeller 530, and the impeller 530 and the main shaft 520 are fixed, and can be fitted with keys. The form of the main shaft 520 is fixed, and the two ends of the main shaft 520 respectively penetrate to the outside of the cylinder 510. The main shaft 520 and the cylinder 510 are matched by bearings. The wall of the cylinder 510 is provided with an air inlet at the blade facing the impeller 530, and the nozzle 540 Set in the air inlet, the wall of the cylinder 510 is provided with an exhaust port; the steam outlet of the steam boiler 6 is connected to the nozzle 540, when the high-p...

Abstract

The invention relates to a biomass gasification and medical waste incineration co-production system. The biomass gasification and medical waste incineration co-production system comprises a gasification furnace, an incinerator, a combustion chamber, a pulverizer, a pneumatic rotating mechanism and a steam boiler, wherein a flue gas outlet of the gasification furnace is communicated with a combustion chamber of the incinerator, and a flue gas outlet of the incinerator is communicated with a flue gas inlet of the combustion chamber; a smoke outlet of the combustion chamber is communicated with asmoke inlet of the steam boiler; a powder outlet of the pulverizer is communicated with a flue gas channel of the combustion chamber; the pneumatic rotating mechanism is connected with a rotating shaft of the pulverizer so as to drive the rotating shaft to rotate; and a steam outlet of the steam boiler is communicated with an air inlet of the pneumatic rotating mechanism, and an air outlet of thepneumatic rotating mechanism is communicated with a powder outlet of the pulverizer. High-temperature combustible gas generated by the gasification furnace enters the incinerator and can support combustion of medical waste for incineration; and flue gas generated by the incinerator, carbon powder and high-pressure steam enter the combustion chamber, so that a large amount of heat energy can be generated through secondary proportioning, mixing and combustion, and the heat energy yield is effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical waste and biomass treatment, in particular to a biomass gasification and medical waste incineration co-production system and method. Background technique [0002] Biomass mainly refers to lignocellulose (lignin for short) such as straw and trees other than grain and fruit in the process of agricultural and forestry production, leftovers of agricultural product processing industry, agricultural and forestry waste and other substances. [0003] The annual production of crop straw in the country is about 600 million tons, about 300 million tons can be used as fuel, and the annual available forestry waste is about 900 million tons, about 300 million tons can be used as energy. Incineration not only wastes resources, but also pollutes the air. [0004] Medical waste refers to directly or indirectly infectious, toxic and other hazardous waste produced by medical and health institutions in medical treat...
