Problems solved by technology

[0005] Although most of the mud scrapers on the market can effectively remove the soil in the sewage, due to the large amount of impurities and turbidity in the sewage, some small molecules in the sewage The impurities cannot be filtered out, and it is not convenient to further filter and purify the sewage. Therefore, it is necessary to improve the existing equipment to meet the needs of sewage treatment.
[0006] Twin-shaft mixers are widely used in enterprises. Enterprises can mix products through twin-shaft mixers, saving manpower consumption. At the same time, with the continuous development of technology With the development, the twin-shaft mixer is also constantly innovating. There will be many types of twin-shaft mixers on the market, and the structure is relatively large, but some twin-shaft mixers lack a structure that facilitates the installation of the device. improve on the basis of
[0007] Although there are many types and quantities of exhaust gas spray towers on the market, they have the following disadvantages: exhaust gas spray towers do not have the ability to collect rainwater As a result, the water level of the water tank of the exhaust gas spray tower cannot be observed in time and the inside of the water tank of the exhaust gas spray tower is not convenient for cleaning and maintenance

Abstract

Provided are a sludge drying treatment system for water conservancy and hydropower engineering and an operation method thereof. Non-dewatered sludge is separated into liquid-phase sewage and dewateredsludge through a centrifugal machine, the liquid-phase sewage is discharged into a sewage treatment plant to be treated, the dewatered sludge is conveyed to a wet sludge bin, waste gas is conveyed into a waste gas spraying tower through a discharging pipeline to be treated, and the waste gas treated by the spraying tower is conveyed into a factory deodorization system through a waste gas air blower; the wet sludge material is conveyed to a sludge distributor through a double-shaft screw conveyor, the uniformly distributed and spread sludge is cut into noodle shapes by a sludge noodle shape forming machine, and the noodle-shaped dried sludge is scraped by a sludge scraper; a cooling screw conveyor cools the noodle-shaped sludge with waste heat, and the completely cooled noodle-shaped sludge is fed into a dry sludge bin and finally fed into dried sludge to be treated; the noodle-shaped sludge which is not completely cooled is conveyed into a crusher, mixed, and conveyed into the sludgedistributor again for circulation.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a sludge drying treatment system for water conservancy and hydropower engineering and an operating method thereof. Background technique [0002] Although there are many types and quantities of wet sludge silos with biaxial screw conveyors at the bottom on the market, the wet sludge silos with biaxial screw conveyors at the bottom have such shortcomings: the existing sewage Due to its huge size, the mud silo is usually placed outdoors. However, the top of the sludge silo is exposed, and the user cannot work in rainy weather when maintaining the sludge silo. Therefore, a rain-shielding device is needed. Therefore, the wet sludge silo that the current bottom is provided with a biaxial screw conveyor is improved. [0003] However, when most of the mud distributors on the market are processing materials, because the feeder does not have a machine ...
