Pulse gas explosion type municipal wastewater and garbage treatment device with tail heat utilization and centrifuge

Abstract

The invention discloses a pulse gas explosion type municipal wastewater and garbage treatment device with tail heat utilization and a centrifuge. The pulse gas explosion type municipal wastewater andgarbage treatment device comprises a large sewage tank, an incinerator, a counter-current drying tower, the horizontal spiral centrifuge, a sine roller and a heat pump host. A municipal wastewater pipe is connected with a wastewater buffer tank. A grid slag catcher is arranged in the buffer tank. The grid slag catcher is connected with a centrifugal dehydrator through conveying. The wastewater buffer tank is connected with an inlet of the large sewage tank through a sewage pipe and a sewage pump. An appropriate number of mixing devices and a protruding rib ultrasonic wave shock excitation mixer are arranged in the large sewage tank. A conical bottom is connected with a Roots blower, a bottom valve and a mud pump through a pipeline. The mud pump is sequentially connected with the horizontalspiral centrifuge, a spiral airlock feeding machine and the countercurrent drying tower. A tail gas pipe of the drying tower is connected with a heat pump system. A cosine plastic disc pulse gas explosion device is arranged on the lower left portion of the drying tower. According to the pulse gas explosion type municipal wastewater and garbage treatment device, the sine roller, the cosine plasticdisc pulse gas explosion device and the protruding rib ultrasonic wave shock excitation mixer all have the distinctive features and can reliably cooperate with one another to complete the municipal wastewater and garbage treatment.

Description

technical field [0001] The invention relates to a pulse-explosive urban wastewater garbage treatment device with tail heat utilization and a centrifuge. 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 ...

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
