Abstract
The invention discloses an incineration and tail gas treatment process for waste tires. The process comprises the following steps that the waste tires are subjected to efflorescence treatment and then are smashed, the smashed tires are fully combusted, and tail gas generated due to combustion is oxidized; and the oxidized tail gas is led into water to be filtered, the filtered tail gas is subjected to chemical purification and then adsorbed by tail gas carbon adsorbents and exhausted. The waste tires are recycled by being converted to thermal energy and tail gas absorption treatment is conducted at the same time, in this way, resources are repeatedly used to the largest extent, and pollution is reduced.
Description
Technical field
The present invention relates to a kind of incineration and tail gas treatment process of junked tire.
Background technology
Along with the development of science and technology, bring the very fast development of auto industry.Automobile quantity sharply surging, causes the quantity of waste tire constantly to increase.If directly carry out concentrated combustion to junked tire, then the tail gas produced that burns can cause serious pollution to environment; Stack if concentrate, then can grow various bacterium, easily cause transmission, floor space is large, is difficult to natural degradation; If carry out degraded to junked tire to recycle process, then cost is excessive, and processing procedure is quite loaded down with trivial details, and it is not high to process the utilization rate after reclaiming yet.Therefore, the research and development for junked tire treatment technology are Tough questions.
Summary of the invention
For above problems of the prior art, the invention provides a kind of incineration and tail gas treatment process of junked tire, the method recycles by junked tire being converted into form of thermal energy, carry out tail gas absorption process simultaneously, achieve the recycling of resource to the full extent and reduce pollution.
Technical problem to be solved by this invention realizes by the following technical solutions:
The incineration of junked tire and tail gas treatment process, is characterized in that, comprises the following steps:
1) weathering process is carried out to junked tire;
2) pulverization process is carried out to junked tire;
3) Thorough combustion is carried out to the tire after pulverizing;
4) tail gas produced in step 3 is oxidized;
5) tail gas of step 4 is passed in water, filter;
6) to the tail gas clean-up of step 5;
7) the tail gas carbon adsorbent of step 6 is adsorbed and discharged.
Preferably, step 2) described in pulverization process, first with cutting machine, waste and old tire is cut into fragment, then to the fragmented junked tire of cutting, carries out degree of depth pulverizing with pulverizer.
Preferably, step 3) pulverize after tire be placed in calcining furnace and burn, and to ventilate with hair-dryer.
Preferably, step 4) described in oxidation be carrying out containing in the sealing device of oxide.
Preferably, step 6) described in purification carry out in spray absorber, install reverberation bowl above spray absorber, below arranges and receives the pipeline of waste liquid, tail gas enters from tower body bottom, and reactant liquor enters from the reactant liquor conveyance conduit with pressure upwards of the mouth of pipe below reverberation bowl.
Preferably, described reactant liquor is sodium hydroxide solution.
The invention has the beneficial effects as follows: the combustion rate that improve junked tire, achieve the conversion of energy more than 95%, greatly reduce Dust Capacity, greatly improve vent gas treatment industrial system, harmful substance after burning is discharged after oxidative absorption again, greatly reduces pollution level, and can not secondary pollution be produced, be a kind of efficient and extremely oligosaprobic application technology, operating cost is low.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The incineration of junked tire and tail gas treatment process:
Carry out weathering process to junked tire, carry out pulverization process to junked tire, the junked tire after weathering relatively aridity is better, is easier to the pulverization process to junked tire; Carry out Thorough combustion to the tire after pulverizing, be oxidized by the tail gas that burning produces, carbon monoxide and hydrocarbon conversion containing carbon monoxide and hydrocarbon, can be carbon dioxide after carrying out oxidation by junked tire in the tail gas of burning generation; Tail gas after peroxidating is passed in water, filters, filter out some poisonous water-soluble materials in tail gas; To the tail gas clean-up after filtration, adsorb and discharge the tail gas carbon adsorbent after purification, advantages of good adsorption effect, exhaust emission is low.
Pulverization process, first with cutting machine, waste and old tire is cut into fragment, then to the fragmented junked tire of cutting, degree of depth pulverizing is carried out with pulverizer, application cutting machine carries out cutting process to junked tire, can not produce dusty gas and dust, and the degree of depth being convenient to pulverizer is pulverized, be convenient to the contact area increasing burning, make the more abundant of burning.
Tire after pulverizing is placed in calcining furnace and burns, and ventilates with hair-dryer, and ventilation can improve efficiency of combustion, and the heat produced for burning can utilize further, is used as thermal power generation, heating, heat power etc.
Oxidation is carrying out containing in the sealing device of oxide, be further oxidized the carbon monoxide contained in tail gas and hydrocarbon, reduces and pollutes.
Purification is carried out in spray absorber, above spray absorber, reverberation bowl is installed, below arranges the pipeline receiving waste liquid, tail gas enters from tower body bottom, reactant liquor enters from the reactant liquor conveyance conduit with pressure upwards of the mouth of pipe below reverberation bowl, containing flue dust, benzene homologues, cyanide, sulfide, carbon monoxide and hydrocarbon that burn incompletely produces in the tail gas of burning, the contact area of increase and reactant liquor, fully absorbs and disposes produced venomous injurant.
Reactant liquor is sodium hydroxide solution, good absorbing effect.
The present invention recycles by junked tire being converted into form of thermal energy, carries out tail gas absorption process simultaneously, achieves the recycling of resource to the full extent and reduce pollution.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
