Description

A kind of waste incineration and generating electricity UTILIZATION OF VESIDUAL HEAT IN and smoke processing system

Technical field

This utility model is related to a kind of waste incineration and generating electricity system, remaining in more particularly, to a kind of waste incineration and generating electricity system Heat utilization and smoke processing system.

Background technology

With the development of Chinese Urbanization's, domestic waste is continuously increased, such as inappropriate process, will endanger ecological ring Border and human health.Domestic waste conventional treatment method has landfill, compost and a burning electricity generation, wherein waste incineration and generating electricity because Process more thoroughly, volume reduction amount is big, process time is short, floor space is little, the advantages of reclaim heat energy, and receive much attention, obtain very fast Development.

The core of burning electricity generation system is the effective process making full use of with combustion product gases of calory burning, and existing burning is sent out In order to make full use of the heat of burning in power technology, someone devises off-gas recovery and utilizes system, but not to waste heat recovery Using after flue gas be effectively treated, thus result in serious atmospheric pollution.

Utility model content

The purpose of this utility model is to design a kind of waste incineration and generating electricity system, solve above-mentioned of the prior art not Foot, that is, by waste incineration and generating electricity system of the present utility model, had both enabled the recycling of waste heat, had made full use of waste incineration The heat producing, the flue gas after again making full use of flue gas is effectively treated, and does not result in atmospheric pollution.

Waste incineration and generating electricity system of the present utility model is realized by following concrete structure：

Waste incineration and generating electricity UTILIZATION OF VESIDUAL HEAT IN and smoke processing system include magnetic garbage sorting machine, garbage pulverator, rubbish Drying equipment, combustor, furnace slag brick making equipment, heat exchanger, steam-driven generator and smoke processing system, raw refuse first by Conveyer device is delivered to magnetic garbage sorting machine, and raw refuse is separated into metal garbage and nonmetallic by magnetic refuse classification function Rubbish, metal garbage is recovered, and nonmetallic rubbish is transported to garbage pulverator and is pulverized, then in garbage drying equipment It is dried, is transported to combustor through dried rubbish and is burned, the slag after burning is transported to furnace slag brick making Make building concrete brick in equipment, burn the steam producing through heat exchanger heat exchange, generated electricity for steam-driven generator.

Further, the flue gas of above-mentioned heat exchanger gas outlet is delivered in garbage drying equipment to rubbish by conveyance conduit It is dried, pick up the heat more than realization.

Further, above-mentioned smoke processing system is arranged on the gas outlet of garbage drying equipment, pond is dried, removes including Calx Dirt equipment, desulphurization plant, the flue gas in garbage drying equipment is dried pond through Calx first and is dried, and then removing dust equipment removes Dirt, after through desulphurization plant process after be emitted in air.

Further, above-mentioned cleaner includes being sequentially arranged bulky grain filter collector, fiber bag precipitator, quiet Electric cleaner, described flue gas sequentially passes through above-mentioned cleaner unit and carries out dedusting.

Waste incineration and generating electricity system of the present utility model can produce following beneficial effect：

1st, can effectively raw refuse be sorted using magnetic garbage sorting machine, the high metal of screening bid value valency Garbage reclamation utilizes, the recovery value of lifting rubbish；Do not comprise metal garbage additionally, due to the rubbish after sorting, therefore not But it is easy to follow-up pulverization process moreover it is possible to improve combustion thermal efficiency.

2nd, using the waste heat after generating electricity of burning away the refuse, the rubbish after pulverizing is dried with the recovery profit it is achieved that waste heat With improve capacity usage ratio；Using cleaner and desulphurization plant, flue gas is effectively treated, does not result in air dirty Dye.

Brief description

Fig. 1 is the structural representation of this utility model waste incineration and generating electricity system.

Specific embodiment

With reference to embodiment, this utility model is described in further detail, but embodiment of the present utility model does not limit In this.

The structure of waste incineration and generating electricity system of the present utility model is as shown in figure 1, include magnetic garbage sorting machine, rubbish powder Broken machine, garbage drying equipment, combustor, furnace slag brick making equipment, heat exchanger, steam-driven generator and smoke processing system, original Rubbish is delivered to magnetic garbage sorting machine by conveyer devices such as conveyer belts first, and raw refuse is separated by magnetic refuse classification function Become metal garbage and the nonmetallic rubbish such as iron and steel class, metal garbage is recovered, and nonmetallic rubbish is transported to garbage pulverator and enters Row pulverize because metal garbage screened go out, pulverize become to be relatively easy to, then pulverize after rubbish rubbish do It is dried in dry equipment, is transported to combustor through dried rubbish and is burned, because have passed through pulverizing and being dried Step, so the firing efficiency of rubbish is higher, the slag after burning be transported in furnace slag brick making equipment makes for building mixed Solidifying cob brick, burns the steam producing through heat exchanger heat exchange, is generated electricity for steam-driven generator.

The flue gas of above-mentioned heat exchanger gas outlet is delivered in garbage drying equipment by conveyance conduit and rubbish is dried, Pick up the heat more than realization.

Above-mentioned smoke processing system is arranged on the gas outlet of garbage drying equipment, pond, cleaner is dried, takes off including Calx Sulfur equipment, the flue gas in garbage drying equipment is dried pond through Calx first and is dried, then the dedusting of removing dust equipment, after warp Desulphurization plant is emitted in air after processing.Above-mentioned cleaner includes bulky grain filter collector, the cloth bag being sequentially arranged Formula cleaner unit, electrostatic precipitator, described flue gas sequentially passes through above-mentioned cleaner unit and carries out dedusting, through the filtration cigarette of above-mentioned cleaner unit Solid grain contamination in gas can be fully achieved the discharge standard of country, and gas pollutant purifies through desulphurization plant, also keeps away Exempt from atmospheric pollution.

The foregoing is only preferred embodiment of the present utility model, be not limited to utility model, although reference Previous embodiment has been described in detail to this utility model, and for the technical staff in wooden field, it still can be right Technical scheme described in foregoing embodiments is modified, or carries out equivalent to wherein some technical characteristics.All Within the spirit of utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in utility model Within protection domain.
