Burn if garbage power is controlled proper, OK to environmental influence very small. But, if the control processing of process and tail gas, residual to burning, liquid waste is undeserved, cause pollution likely also 2 times, this must notice.
Rubbish burns generate electricity the harmful material that can produce includes: Flue gas pollutes what get attention quite among them is " 2 evil flower " and burn liquid waste of the generation in the process and fluid of rubbish ooze drop, having again is grey broken bits and dust, but major rubbish of nowadays our country burns the contaminative control that generate electricity amounts to mark basically already.
Prevention and cure reachs measure
1, the setting does system of law to decoke partly
2, use efficient hop-pocket dust catcher
3, chimney stack is discharged (by environmental protection requirement height increases 40 meters) contaminant diffuses through dilute, be born chroma is reduced, can reduce the effect to the environment effectively.
4, rubbish burns main harm is 2 evil flower pollution, 2 evil flower have send cancerous sex by force.
(1) even control is in the temperature inside furnace 850, 950 ℃ ;
(2) retention period is more than 3 seconds;
(3) burn gas indoor and sufficient mix, ≥ of content of the oxygen in incinerator export flue gas 6% ;
(4) use limestone to decoke, take off inside implementation furnace at the same time chloric, poriferous activated carbon is right 2 evil flower also have certain sorption.
(5) to the flue gas that has produced medium 2 evil flower can use activated carbon adsorption, catalysis to decompose, ultraviolet light is decomposed, microbial degradation and integrated and electrostatic flue gas are purified wait for a method to undertake handling.
5, processing of fluid of rubbish ooze drop
Fluid of rubbish ooze drop basically arises at rubbish storehouse, rubbish storehouse is used close the structure that prevent ooze. Boiler has adoption circular fluid-bed condition of the processing that answer gush, ooze drop fluid uses sewage pump pressurization to undertake answering gush furnace inline processing entirely.
6, processing of grey broken bits
The project eliminates broken bits system, use cent of grey broken bits to divide, means of dry grey dry platoon. Slag can undertake be used integratedly or be fillinged burying directly, slag carries a system to use the mechanical means that divide broken bits, with blow trigger to send broken bits the storehouse, outside reaching a plant by use of automobile of carry broken bits use integratedly. At the same time garbage power factory has online supervisory system, each instant data (be like: The temperature inside furnace, 2 evil flower discharge capacity) show immediately go up in big screen.
Optional location of garbage power plant asks
Hair of total bureau of national environmental protection, country changes appoint release jointly generate electricity the announcement that project environment affects evaluation management to work " 2006 〕 of 〔 of 〔 annulus hair the regulation of 82 〕 . Specific provision burns about life rubbish generate electricity the specific requirement that category looks the site of factory chooses, outside stipulating the requirement divides country and local code, standard, policy to prohibit polluting the area of category eye optional location, the following area must not build life rubbish to burn commonly generate electricity category eye: (1) big in urban building area and town planning area; (2) town or what center wind direction of residential area dominant greatly is windward to; (3) the likelihood creates sensitive division the area that environmental protection target cannot reach corresponding standard to ask.
