Description
Technical field
The present invention relates to a kind of solid burning waste residue resource and utilize disposal technology, specifically a kind of hazardous waste waste gas disposing technique and equipment.
Background technology
Making solid waste reducing, innoxious administering method have: sanitary landfills, centralized burning, recycling resource etc., burning disposal is increasingly used by a lot of countries because of the advantage of himself uniqueness, the important means of Ye Shi China solidification disposal of waste.When using this processing mode, solid dangerous waste has quite a few solid waste, barreled liquid needs to be crushed by disintegrating machine, deliver to compound hole after Po Sui mix, and crush and mixed process can produce organic volatile and overflow, even more than explosion limit, careless slightly will result in is caught fire or detonation.
Major part producer uses and delivers to exhaust gas processing device by air-introduced machine or partly deliver to incinerator as combustion air at present, but, the organic volatile substrate concentration that broken and mixed process produces is high, high by exhaust gas processing device operating cost, the most also produce the secondary pollution such as waste water or waste active carbon；Being passed to incinerator, incinerator uses air quantity limited, it is impossible to meet demand of bleeding, additionally containing a large amount of volatile matters in air, in fact it could happen that reaching explosion limit, incinerator is open firing point, can cause detonation, has great potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of organic volatile substrate concentration that can reduce in confined space and abnormal smells from the patient, improves site environment, reduces vent gas treatment cost and does not produce hazardous waste waste gas disposal facility and the technique of secondary pollution.
In order to solve above-mentioned technical problem, the hazardous waste waste gas disposal facility of the present invention, including the batch mixing pond arranged in Factory Building, the gas outlet in batch mixing pond connects scrubbing tower by outlet pipe, air-introduced machine is installed on outlet pipe, the bottom side of scrubbing tower is provided with emulsator, and the export pipeline of emulsator is connected to the entrance of burner and the top of scrubbing tower after a circulating pump, and the top exit of scrubbing tower is by respectively leading in rotary kiln and Factory Building communicating pipe.
Described batch mixing pond be provided above disintegrating machine, be provided with feed well between the open top in described disintegrating machine and batch mixing pond, the top of described disintegrating machine is provided with feed hopper.
A kind of hazardous waste waste gas disposing technique using above-mentioned hazardous waste waste gas disposal facility, comprises the following steps:
A, fuel and alkali liquor are proportionally added in emulsator, through being sufficiently stirred for emulsifying, prepare oil-water emulsion；
B, joining in scrubbing tower by emulsion through the export pipeline of emulsator, ON cycle pump is circulated washing；
C, opening air-introduced machine, carry out blended absorbent with oil-water emulsion in the organic volatile that batch mixing pond produces being delivered to scrubbing tower by air-introduced machine, the gas after absorption cleaning is through delivering to rotary kiln communicating pipe or being discharged in Factory Building；
D, liquid after absorption cleaning deliver to the entrance of burner through circulating pump after returning to emulsator.
Described fuel is 1:9 ~ 9:1 with the ratio of alkali liquor.
Described fuel is natural gas, diesel oil, tire oil or heavy oil, and described alkali liquor is sodium hydroxide, potassium hydroxide or carbamide.
nullAfter using above-mentioned equipment and method，Due to the air-introduced machine arranged between batch mixing pond and washing pump，The circulating pump arranged between emulsator and emulsator and washing pump that the bottom side of scrubbing tower is arranged，Thus the Organic substance volatile matter or the powder body that produce in disintegrating machine and mixed process effectively can be absorbed，Reduce the organic volatile substrate concentration in confined space and abnormal smells from the patient or powder concentration，Improve site environment，Reduce security risk simultaneously，Use emulsifying agent and alkali liquor that diesel oil (heavy oil) is carried out emulsifying by a certain percentage，The acid gas produced in disintegrating machine and mixed process can be absorbed simultaneously，Prevent the corrosion of equipment and Factory Building，The material being dissolved in oil be dissolved in water can be absorbed by diesel oil (heavy oil) and water respectively，Acidic materials are neutralized by alkali，The diesel oil (heavy oil) after emulsifying is used to improve fired state，Decrease the discharge of sulfur dioxide，Secondary pollution will not be produced and decrease the expense of vent gas treatment.
