[technical field]
It belongs to the field of energy saving and environmental protection equipment and technology, and is especially suitable for the preparation of rotary kiln type continuous distillation coke gasification incinerator for the incineration of medical waste or industrial waste (including hazardous waste).
[background technology]
The existing rotary kiln equipment generally has the characteristics of high kiln temperature, low combustion chamber temperature, fuel or gas supporting combustion, which increases the operating cost of enterprises.
The technology discloses a preparation method of rotary kiln type waste incinerator.It consists of round kiln pipe, kiln head cover body, kiln cover body, sealing device, burner, tuyere, exhaust port, feed port, ash outlet, driving device, fire-resistant connection and so on.Suitable for incineration.Household garbage, industrial waste and toxic and harmful substances are a kind of environmental mechanical equipment.The device has the advantages of simple structure, low cost, continuous combustion of various kinds of waste, high combustion rate and convenient use.If this technology is not adopted, the following defects exist: because the traditional rotary kiln is used to treat medical waste or industrial waste (including hazardous waste), the kiln body is not uniform in the gas supply, leading to the combustion of materials in the kiln body;The purpose of dry distillation, pyrolysis and gasification cannot be achieved, resulting in insufficient gas volume and low temperature in the combustion chamber.It cannot meet the relevant environmental requirements of the country, so it needs fuel or gas to support combustion, which directly increases the operating costs of enterprises.
[development]
The purpose of the invention is to provide a preparation method of rotary kiln type incinerator used for continuous distillation. The material is dried, rolled and uniformly heated in the furnace by continuously rotating the furnace body.Drying, pyrolysis and gasification.In order to achieve the above purposes, rotary kiln type continuous dry distillation, pyrolysis and gasification gasifier is adopted, including feeding device, kiln body rotary device, dry distillation, pyrolysis and gasification device, and exhaust gas device. Its characteristics are as follows:
The right end of the kiln body rotary device is equipped with a feed device, the left side of the kiln body rotary device is equipped with a dry distillation pyrolysis gasification device, and the left end of the dry distillation pyrolysis gasification device is equipped with a exhaust gas purification device.The rotary kiln of the kiln body includes a rotary kiln, and the dry distillation pyrolysis gasification unit includes a distillation chamber, two combustion Chambers and exhaust gas purification package.It includes cyclone dust collector, waste heat boiler, quench tower, neutralizer, bag dust collector, fan, spray washing tower and chimney.Amber, the outlet of the distillation chamber is connected with the lower inlet of the two Chambers, the upper outlet of the combustion chamber is connected with the inlet of the cyclone dust collector, and the top outlet of the cyclone dust collector is connected with the top inlet of the waste material.The lower outlet of the feed boiler and the waste heat boiler is connected with the top inlet of the quench tower, and the lower outlet of the quench tower is connected with the lower inlet of the neutralization tower, and the upper outlet of the neutralization tower and the bag dust collector enter.The outlet of the bag filter is connected to the lower outlet of the spray tower through the outlet of the fan and the air duct, and the upper outlet of the spray washing tower is connected to the chimney.
The rotary kiln is transverse, the included Angle between the Central Line of the rotary kiln and the horizontal plane is acute, and the Central Line of the rotary kiln is lower than the Central Line of the feeding device.
A deflector is arranged inside the rotary kiln to rotate the material forward and discharge continuously.
The materials in the distillation chamber produce combustible pyrolysis gas in the process of total distillation, pyrolysis and gasification.It is fed into two combustion Chambers by a fan, and a rotary continuous discharge device is set at the bottom of the gasification chamber, and the material is discharged through the discharge device after the material.
