Abstract
The utility model discloses a sludge pyrolysis processing device utilizing waste plastic as supplementary energy. Existing pyrolysis technology is high in investment and operating costs when processing sludge which is low in heat value and high in moisture content, and needs auxiliary fuel to achieve system energy supply balance. According to the sludge pyrolysis processing device, the waste plastic is evenly smashed through a smashing device and enters into a drying device together with the sludge to be dried, mixture enters into a pyrolysis device after the water ratio of the mixture is reduced, oil and gas produced through pyrolysis are burned to produce energy which is reused for the pyrolysis device, high temperature flue gas produced through burning enters into a residual heat utilization device to produce saturated steam, the saturated steam is condensed after drying water sludge and the waste plastic inside the drying device, and high temperature residues are cooled by a condensate water sending slag tube and return to the residual heat utilization device. The flue gas of the residual heat utilization device is discharged up to the standard after being processed by a tail gas treating device. The waste plastic has the advantages of being wide in source, high in heat value, large in quantity and the like, the waste plastic and the sludge are mixed to conduct pyrolysis, and therefore lower heat value sludge pyrolysis is achieved.
Description
Technical field
The utility model belongs to technical field of sewage, relates to a kind of with the pyrolyzing sludge treatment unit of waste plastic as the additional energy.
Background technology
Mud has water ratio height, organic content height, degenerates smelly characteristics easily as the product of sewage treatment process, and it is formed, the complicacy of character has determined the difficulty of its disposal, and technology is proposed severe challenge.Domesticly in recent years emerge multiple sludge treatment disposal technology, but weigh with " minimizing, stabilization, resource utilization " three big fundamental principles, the sludge disposal field mass-producing also do not occur and through respond well technical matters and the device systems of practice test at present.Conventional mud: the threats of removal of pollutants fully such as farmland utilization, landfill, burning.The a large amount of utilizations of mud in agricultural can cause the enrichment of heavy metal in soil; The landfill disposal method is except that taking up an area of the big area soil, and soil layer needs complete closed to leak to prevent objectionable impurities; And sludge incineration must adopt expensive treatment facility to prevent the release of gas and solid pollutant.Various treatment technology is often attended to one thing and lose sight of another, and is difficult to reach rational Technological Economy target.
Therefore; Pyrolyzing sludge is used by broad research as the most promising new technology in sludge disposal field, and the solid residue volume reduces greatly after the pyrolysis, and the anti-nature precipitation ability of the heavy metal in the carbon back is stronger; The inflammable gas that generates is higher with the calorific value of oil, can become the promising energy.And pyrolysis has limited the amount of pollutent in the pyrolysis gas that is discharged carrying out than burning under the low temperature, and this process is carried out under anaerobic or anoxia condition, so the generation of no dioxin.But pyrolysis has strict demand to sludge water content content, the sludge calorific value of handling, and for the low mud of calorific value, needs to add the energy-balancing that supplementary energy guarantees system, has so just strengthened the investment and the working cost of pyrolysis system.
Summary of the invention
To the difficult situation of low heat value pyrolyzing sludge; It is a kind of with the pyrolyzing sludge treatment unit of waste plastic as the additional energy that the purpose of the utility model has been to provide, and waste plastic has characteristics such as the source is wide, calorific value is high, quantity is big, price is low, compares auxiliary materials such as adding biomass, fire coal in the mud; Add the high waste plastic of calorific value in proportion; Carry out the mixed pyrolysis of waste plastic and mud, guarantee the energy-balancing of pyrolysis system, have good economy, environment-friendly advantage.
The technical scheme of the utility model is:
A kind of with the pyrolyzing sludge treatment unit of waste plastic as the additional energy, comprise shredding unit, e Foerderanlage, desiccation apparatus, pyrolysis installation, combustion unit, residual heat using device and exhaust gas processing device.
After waste plastic is pulverized evenly by reducing mechanism; It is dry to get into desiccation apparatus with mud by conveying device, and the mixture moisture content of waste plastic and the mud back that descends gets into pyrolysis installation and carries out pyrolysis, and the oil of pyrolysis generation, gas are by the burner produce power of burning; This energy heat supply is separated device and is used; The high-temperature flue gas that the burner burning produces gets into residual heat using device, in residual heat using device, produces saturated vapor, and this steam is sent to desiccation apparatus and is used for dry water-containing sludge and waste plastic; Steam is by condensation behind the desiccation apparatus, and condensed water returns residual heat using device after sending residue outlet that hot-engine sludge is cooled off; The flue gas that residual heat using device produces is accomplished qualified discharge behind cooling, depickling and the dust removal process of combustion product gases by exhaust gas processing device.
The beneficial effect of the utility model is:
(1) saves the energy, practice thrift working cost.Compare with pyrolysis auxiliary fuels such as fire coal, biomass, waste plastic has that the source is wide, quantity is big, price is low, the calorific value advantages of higher, adopts waste plastic and the common pyrolysis of mud, solved the power consumption of low heat value pyrolyzing sludge greatly, problem that cost is high.This device in use all not to the environmental emission objectionable impurities, with the compared with techniques of existing sludge incineration, has been avoided the danger of secondary pollution simultaneously, has embodied the good environmental benefit of this device.
(2) the pyrolysis product treatment step is simple.Obtaining with the oil prod with plastic cracking is that the technology of purpose product is compared, and has simplified oil separating and refinement step, has saved the corresponding apparatus investment.This pyrolysis installation has alleviated the requirement to gas sweetening greatly, has saved the gas cleaning link, has saved the gas cleaning expense.
(3) the ingenious design of reasonable combination of device makes that very low pyrolyzing sludge disposal becomes possibility to Lower heat value, and having overcome the pyrolyzing sludge disposing technique of in the past reporting can only be to the limitation of high heating value refuse.

Fig. 1 is the utility model structural representation.
Embodiment
In order further to understand utility model, the utility model embodiment is described in conjunction with instance.
Fig. 1 is the apparatus structure synoptic diagram that the utility model provided.Comprise shredding unit, e Foerderanlage, desiccation apparatus, pyrolysis installation, combustion unit, residual heat using device and exhaust gas processing device.
After waste plastic is pulverized evenly by reducing mechanism; It is dry to get into desiccation apparatus with moisture content 80% mud by conveying device, and the entering pyrolysis installation carries out pyrolysis when moisture content is reduced to 10% below after, and the oil of pyrolysis generation, gas are by the burner produce power of burning; This energy heat supply is separated device and is used; The temperature that the burner burning produces gets into residual heat using device greater than 1050 ℃ high-temperature flue gas, produces temperature greater than saturated vapor more than 150 ℃, and this steam is sent to desiccation apparatus and is used for dry water-containing sludge and waste plastic; Steam is by condensation behind the desiccation apparatus, and condensed water returns residual heat using device after sending residue outlet that hot-engine sludge is cooled off; The residual heat using device flue gas can be accomplished qualified discharge behind cooling, depickling and the dust removal process of combustion product gases by exhaust gas processing device.
