Technical field
The present invention relates to a kind of treatment technology of house refuse, refer in particular to a kind of domestic garbage gasification electricity generation system, this system reaches the purpose of generating in conjunction with the use of gas turbine.
Background technology
Environmental protection is a fundamental state policy of China, is the important duty of China local governments at all levels.But along with constantly rising up into of China reform and opening-up, economy has obtained developing by leaps and bounds, and city size enlarges day by day, and population constantly increases, and people are to improving constantly that self living environment and environmental practice dynamics require.If house refuse can not get effective processing, can make that the environmental aspect in the zone goes from bad to worse, directly influence people health and living environment, ecological environment is caused very big threat.And now China city every year is because of nearly approximately 30,000,000,000 yuan of recrementitious loss (traffic expense, handling etc.).Processing method for house refuse has at present: landfill technology, composting technology, incineration treatment technology etc.Utilizing garbage power is the focus of a research, and the waste resources of China's abundant has great potential benefit.Analyze according to China big and medium-sized cities component of refuse, its calorific value is all at 800～1500kcal/kg, if incineration firing can be converted into electric energy with its heat energy, and 1 ton of domestic waste of then every burning, the 300～400kW that can generate electricity.Because behind the incineration firing, the rubbish volume reduces 90%, weight reduces more than 75%, obviously meets rubbish and subtracts appearance minimizing processing target.Therefore, if can be with incineration firing and be used to generate electricity and create huge economic benefit and realize environmental protection, energy-conservation, the comprehensive social benefit that reduces discharging.
The utility model content
The purpose of this utility model provides a kind of domestic garbage gasification electricity generation system, and it utilizes the pyrolytic gasification house refuse to generate electricity, and realizes incineration firing is converted into electric energy with its heat energy.
Now realize above-mentioned purpose of the present utility model by the following technical solutions: a kind of domestic garbage gasification electricity generation system comprises the vertical gasification furnace → flue gas purification system → roots blower → gas storage holder → gas engine → waste heat boiler → dioxin emission reducing device that connects successively.Vertical gasification furnace body of heater is from the bottom air feed, and effectively controls oxygen-supplying amount by the computer automation system.The operation principle of this gasification power generation system is: house refuse pushes in the vertical gasification furnace by hydraulic pressure pusher mode; Vertical gasification furnace obviously is divided into levels with rubbish, lower floor is a burning zone, the upper strata is the gasification layer, air at first impels its burning through lower floor's rubbish, the combustion residue charing also produces a large amount of heats, at this moment, because airborne oxygen is almost all consumed, cause upper strata rubbish to be in anaerobic condition and the heat that lower floor incineration firing charing produces is brought into, make upper strata drying garbage pyrolytic gasification, it is the flammable mist that the long strand of organic substance such as tar and so on become short molecular chain in the rubbish through the chemical action cracking of high temperature anoxic, these imflammable gas further react with coke in high temperature reaction zone, and final obtain to contain main combustible gas component be: CO, CnHm, H
2Flammable mist; Tar, dust and sour gas in the flammable mist of gained are washed, are lowered the temperature by flue gas purification system, thereby realize deacidification, dedusting, remove tar and most of steam; Purify back gas again by the roots blower gas storage holder of packing into; Gasification gas from gas storage holder output enters the temperature rising of gas engine heat absorption back, flows into the expansion limit work done of gas turbine limit then and is converted into electric energy, and the gas after the work done enters waste heat boiler and produces steam; Last residual gas will meet the tail gas of gas discharge standard after by the dioxin emission reducing device and discharge.
Rubbish described in the utility model is in combustion process, and the part of after-flame is distributed in the bottom of lower floor's burning zone, and discharges from slag notch, and these slags can be used for brickmaking.
Gas in the gas storage holder described in the utility model can also the condensation tinning supply industrial gas.
The steam that waste heat boiler described in the utility model produces can export trade be used for facilities such as publilc baths, further enlarges the economic benefit that this patent can be created.
Domestic garbage gasification electricity generation system of the present utility model is by with incineration firing gasification and be used for generating, and its enforcement can be created huge economic benefit and realize environmental protection, energy-conservation, the comprehensive social benefit that reduces discharging.
Description of drawings
Fig. 1 is the structure reference diagram under the known vertical gasification furnace duty of rubbish;
Fig. 2 is the workflow diagram of domestic garbage gasification electricity generation system of the present utility model.
The specific embodiment
Now specify the technical solution of the utility model in conjunction with Figure of description:
As shown in Figure 2, a kind of domestic garbage gasification electricity generation system, comprise the vertical gasification furnace 5 → flue gas purification system 6 → roots blower 7 → gas storage holder 8 → gas engine 9 → waste heat boiler 10 → dioxin emission reducing device 11 that connects successively, also comprise raw material house refuse 1, store the storage hole 2 of house refuse and driving, hopper 3 and the hydraulic pressure pusher equipment 4 of transportation rubbish.The domestic garbage gasification electricity generation system is work like this in the present embodiment: house refuse is transported in the hydraulic pressure pusher equipment by driving or hopper from the storage hole, push vertical gasification furnace by hydraulic pressure pusher mode, vertical gasification furnace (as shown in Figure 1) body of heater is from bottom air feed mouth 20 air feeds, and effectively control oxygen-supplying amount by the computer automation system, after 24 chargings of rubbish self-supporting gasification furnace fire door rubbish obviously is divided into levels (21,22), lower floor 22 is a burning zone, upper strata 21 is the gasification layer, air at first impels its burning through lower floor's rubbish, the combustion residue charing also produces a large amount of heats, at this moment, because airborne oxygen is almost all consumed, cause upper strata rubbish to be in anaerobic condition and the heat that lower floor incineration firing charing produces is brought into, make upper strata drying garbage pyrolytic gasification, it is the flammable mist that the long strand of organic substance such as tar and so on become short molecular chain in the rubbish through the chemical action cracking of high temperature anoxic, these imflammable gas further react with coke in high temperature reaction zone 23, and final obtain to contain main combustible gas component be: CO, CnHm, H
2Flammable mist; The flammable mist of gained is disposed in the flue gas purification system from outlet flue 26, and tar wherein, dust and sour gas are washed, lowered the temperature by flue gas purification system, thereby realizes deacidification, dedusting, remove tar and most of steam; Purify back gas again by the roots blower gas storage holder of packing into; Gasification gas from gas storage holder output enters the temperature rising of gas engine heat absorption back, flows into the expansion limit work done of gas turbine limit then and is converted into electric energy, and the gas after the work done enters waste heat boiler and produces steam; At last, shown in Fig. 2 flow process 15, residual gas will meet the tail gas of gas discharge standard after by the dioxin emission reducing device and discharge.
