Description

Sinusoidal Roller Wastewater Garbage Treatment Device with Roots Blower

technical field

The invention relates to a sinusoidal roller waste water garbage treatment device with a Roots blower.

Background technique

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.

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 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.

Urban domestic wastewater and garbage have become a major source of pollution. It is of special significance to treat urban domestic wastewater and garbage with low energy consumption and high efficiency.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a sinusoidal roller type waste water and garbage treatment device with Roots blower.

In order to overcome the deficiencies in the prior art, the present invention takes the following technical solutions:

A sinusoidal roller type wastewater treatment device with a Roots blower, including a large sewage tank, an incinerator, a countercurrent drying tower, a horizontal screw centrifuge and a sinusoidal roller, characterized in that an appropriate amount of agitation device is installed in the large sewage tank , the middle part is equipped with a motor and a machine base and is connected to the lower part of the sinusoidal ultrasonic excitation agitator through a shaft. The agitator and the sinusoidal ultrasonic excitation agitator in the lower part of the agitation device are provided with end shaft sleeves as required and can be controlled by speed regulation. Large sewage The bottom of the tank is conical, and the bottom of the cone is facing the cover-shaped sinusoidal ultrasonic excitation agitator. The bottom of the cone is connected to the bottom valve through the pipeline, and the bottom of the cone is also connected to the outlet of the Roots blower through the pipeline and the air delivery pipeline. The mud pump is connected to the inlet of the horizontal screw centrifuge, and the horizontal screw centrifuge is connected to the motor through a belt. The conveying trough is connected to the sinusoidal roller, the conveying trough and the inlet of the spiral closed air feeder in sequence. The surface of the sinusoidal roller is a continuous sinusoidal surface, and the outlet of the spiral closed air feeder is connected to the upper left part of the countercurrent drying tower, and the inside of the countercurrent drying tower There are stacked sieve-shaped cone buckets and cone discs. The diameter of the cone discs is slightly larger than that of the cone buckets, and there is an electric control material door at the bottom of the cone discs. The upper right part of the countercurrent drying tower is equipped with an exhaust pipe. The bottom of the drying tower is connected, the bottom of the counter-current drying tower is connected to the closed-air discharge machine, and is connected to the feed port of the incinerator through conveying, the steam fin hot air blower is connected to the steam outlet of the incinerator through the steam pipeline, and the ash outlet of the incinerator is connected to the buffer tank; sinusoidal ultrasonic The structure of the exciting agitator is spherical, and the edge of the spherical is a smooth continuous sinusoidal curve, and there are peaks and troughs gradually expanding and continuous divergence from the center of the spherical to the edge.

The urban waste water flows into the large sewage tank through the urban waste water pipe, and an appropriate amount of stirring device is installed in the large sewage tank. The motor and machine base are installed in the middle and drive the lower part of the sinusoidal ultrasonic excitation agitator to rotate at high speed through the shaft. The agitation device and the sinusoidal ultrasonic excitation agitator The end bushing can be set according to the needs and can be controlled by speed regulation. The bottom of the large sewage tank is conical, and the conical bottom is facing the cover-shaped sinusoidal ultrasonic excitation agitator. The conical bottom pipeline is connected with Roots blower, bottom valve and mud pump. The inlet of the mud pump is controlled by a valve. When working, the stirring device, sinusoidal ultrasonic excitation agitator and Roots blower are turned on to complete the chemical addition and gas explosion operations. The high-speed rotation of the cover-shaped sinusoidal ultrasonic excitation agitator can obviously produce cavitation similar to ultrasonic waves. Effect, combined with the strong centrifugal effect and the blowing of a large amount of air by the Roots blower, an extremely complex sewage effect and mixing effect are produced. After the operation is completed, the static settlement is carried out; after the static settlement is completed, the mud pump can be started to transport the sewage to the large tank through the pipeline The mud deposited at the bottom goes to the horizontal screw centrifuge for continuous solid-liquid separation. The purified water output from the large end on the left side of the centrifuge is buffered and discharged through the water tank, and the dewatered sludge output from the small end on the right is input into the inlet of the screw closed air feeder. After the muddy water at the bottom of the large sewage tank is output and treated, the clear upper water can be discharged directly; the municipal waste is introduced into the sinusoidal roller through the conveying tank for strong crushing to achieve homogenization and crushing, making it easy to dry and process. Then it is input into the feed port through the conveying tank, and the dewatered sludge and dehydrated garbage are combined into the countercurrent drying tower for countercurrent drying operation. The bottom of the dryer outputs dry garbage through the closed air discharge machine, and the garbage is transported to the incinerator for incineration. The incinerator controls the steam delivery to the countercurrent drying tower through valves and steam pipes, and the steam fin hot air blower provides the drying heat source. The incineration residue output from the incinerator is temporarily stored in the buffer tank and used as fertilizer for crops, pastures, and forest trees. The incineration tail gas is discharged through the boiler tail gas pipe for subsequent treatment.

The upper part of the counter-current drying tower has a spiral closed-air feeder and an exhaust pipe. There are stacked sieve-shaped cone buckets and cone disks inside. The diameter of the cone disks is slightly larger than that of the cone buckets. Controlled vibration and electronically controlled door opening and closing facilitate material diffusion, stay dry and can also move downward layer by layer, so that the material can form countercurrent contact with the rising hot air to transfer heat and mass transfer to achieve countercurrent drying. The hot and humid exhaust gas is discharged from the exhaust pipe to dry the material. Then it is output through the closed-air discharge machine, and then transported to the incinerator for incineration. The air blown by the blower is heated by the steam-fin hot air blower, and the high-temperature air passes through the drying tower from bottom to top.

The treatment device can continuously process urban wastewater and garbage, which is convenient for efficient drying, incineration and degradation of urban domestic waste.

Compared with prior art, the beneficial effect of the present invention also lies in:

The sinusoidal roller bites the material continuously and reliably, and has excellent extrusion, rubbing and grinding garbage homogenization function, and at the same time, the energy consumption is particularly low;

The mechanical ultrasonic excitation agitator drives the energy to rotate at high speed through the power mechanism in the liquid phase, which produces a strong cavitation effect similar to ultrasonic waves, and cooperates with centrifugal action, Roots blower blowing, and diffusion explosion to promote sewage treatment and mixing for subsequent follow-up Let the impurities settle and accumulate.

Both of the above two measures have distinctive features, can reliably and collaboratively complete the treatment of urban wastewater and garbage, have completely unexpected working principles and effects, and at the same time, the design scheme also has strong creativity and good prospects for promotion and application.
