Description
Technical field
The invention belongs to municipal solid waste incineration processing technology field, more particularly to a kind of domestic waste, city
The collaboration burning disposal electricity generation system of sludge, kitchen garbage and medical waste.
Background technology
MSW mainly has domestic waste, municipal sludge, kitchen garbage and medical waste.With state inner city
The continuous expansion of city's scale, urban population is continuously increased, domestic waste, municipal sludge, kitchen garbage and medical waste
Pollution turn into environmental problem increasingly serious, urgently to be resolved hurrily.
The complicated component of domestic waste, fluctuation is big, with lasting harm, main at present to use landfill and burn
Technology is handled.Encourage to carry out using burning electricity generation technology for the city that Output of Domestic Waste is larger, calorific capacity is higher
Domestic rubbish disposal, can so reduce garbage disposal land occupation area, reduction secondary pollution, realize the harmless of garbage disposal
Change, minimizing, recycling.
As shown in figure 1, Msw Incineration Power-generating System 100 includes, rubbish receives storage and supply unit 110, burning are single
Member 120, heat energy utilization unit 140, gas cleaning and exhaust unit 130 and percolate processing unit 150.Using cram packer
House refuse is directly delivered into rubbish and receives storage and supply unit 110, is then delivered to using garbage grab bucket and burns unit 120
Waste incinerator is burned.Burn the heat produced to be absorbed by burning the waste heat boiler of unit 120, waste heat boiler production
Raw steam is delivered to heat energy utilization unit 140 and generated electricity.The regulating reservoir of percolate processing unit 150 receives rubbish and receives storage
With the percolate of supply unit 110, reached after percolation liquid treating system is handled《Integrated wastewater discharge standard》In
Discharged after primary standard.It is combustion-supporting to burn that the biogas that percolate processing unit 150 is produced delivers to burning unit 120.Burn single
The flue gas that member 120 is produced is discharged by gas cleaning with being reached after the processing of exhaust unit 130 after standard.
Municipal sludge is mainly derived from municipal sewage plant, with moisture is high, content of organics is high, contain a huge sum of money
It is the features such as belonging to pollutant, main using landfill, compost and incineration treatment technology at present.Using sludge anhydration burning treatment technology
When, it is necessary to be equipped with municipal sludge desiccation unit, burn unit, gas cleaning and exhaust unit, floor space is big, and system investments take
With height, and because municipal sludge calorific capacity is relatively low, it is necessary to add auxiliary fuel, operating cost is high.
