Urban waste water and garbage treatment device with tail heat utilization function and tail gas purification function

Abstract

The invention discloses an urban waste water and garbage treatment device with a tail heat utilization function and a tail gas purification function. The device comprises a large sewage tank, an incinerator, a countercurrent drying tower, a heat pump host and a computer control system, wherein an urban waste water pipe is in connection with a waste water buffering tank; the waste water buffering tank is internally provided with a grating slag extractor; the waste water buffering tank is connected with an inlet of the large sewage tank through a pipeline and a pump; stirring devices and a sinusoidal ultrasonic vibration stirrer are arranged in the large sewage tank; a cone bottom is connected with a roots blower, a bottom valve and a mud pump through pipelines; the mud pump is sequentiallyconnected with the horizontal spiral centrifuge, a spiral closed air feeding machine and the countercurrent drying tower; a tail gas pipe of the drying tower is connected with a heat pump system; a cosine rubber disc pulse detonation device is arranged on the left lower part of the drying tower; a boiler tail gas pipe and a incineration tail gas treatment device are sequentially connected to theright upper part of the incinerator; and the treatment device is controlled by a computer. According to the urban waste water and garbage treatment device with the tail heat utilization function and the tail gas purification function, a sine roller, the cosine rubber disc pulse detonation device and the sinusoidal ultrasonic vibration stirrer have distinct characteristics and can be used for reliably and cooperatively finishing the treatment of the urban waste water and garbage.

Description

technical field [0001] The invention relates to an urban waste water garbage treatment device with tail heat utilization and tail gas purification. Background technique [0002] The current urban water pollution problem is very serious, and there is a great demand for water pollution prevention and treatment. At present, in the field of sewage treatment and water resource reuse, the level of development is relatively low, the infrastructure is weak, and there is still a big gap compared with developed countries. [0003] At present, domestic waste treatment is mainly based on sanitary landfill, accounting for about 78% of the treatment volume, and the classification and subdivision of waste is not strong, and there is no more effective recycling route. Domestic waste treatment is at a relatively early stage, and there are many aspects that need to be standardized from the source to the final treatment, such as classification, recycling, and treatment methods. At this stage...

AI Technical Summary

Problems solved by technology

At this stage, it is mainly for the treatment of the generated waste, and the treatment method is relatively simple, mainly the way of sanitary landfill. Due to the lack of detailed classification, the recycling rate of resources is very low
