Pulse detonation gas type municipal wastewater waste treatment device with granulator

Abstract

The invention discloses a pulse detonation gas type municipal wastewater waste treatment device with a granulator. The pulse detonation gas type municipal wastewater waste treatment device comprises asewage large trough, an incinerator, a countercurrent drying tower, a horizontal-type spiral centrifuge and a sine roller; a municipal wastewater pipe is connected with a wastewater buffer trough, and a grille slag salvaging machine is arranged in the buffer trough and is connected with a centrifugal dewatering machine in a conveying mode; the wastewater buffer trough is connected with an inlet of the sewage large trough through a sewage pipe and a sewage pump; stirring devices and protruding-rib ultrasonic vibration exciting stirrers are arranged in the sewage large trough in a proper amount; a conical bottom is connected with a roots blower, a bottom valve and a slurry pump through pipelines; the slurry pump is sequentially connected with the horizontal-type spiral centrifuge, a spiralclosed-wind feeder and the countercurrent drying tower; a tail gas pipe is arranged on the upper right part of the drying tower, and a cosine rubber disk pulse detonation gas device is arranged on thelower left part of the drying tower; and an ash outlet of the incinerator is sequentially connected with the buffer trough and the granulator. According to the pulse detonation gas type municipal wastewater waste treatment device with the granulator, the sine roller, the cosine rubber disk pulse detonation gas device and the protruding-rib ultrasonic vibration exciting stirrers have distinct characteristics and can reliably and synergistically complete municipal wastewater and waste treatment.

Description

technical field [0001] The invention relates to a pulse explosion type urban waste water garbage treatment device with a granulator. 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, it is mainly ...

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
