Examples
Referring to fig. 1 to 2, in one aspect, the present embodiment provides a sewage concentrating apparatus including: a water inlet pipe 4, an outer cylinder 3 and an inner cylinder 5;
wherein, the diameter of the inner cylinder 5 is smaller than that of the outer cylinder 3; the inner cylinder 5 is coaxially arranged in the outer cylinder 3, and an outlet at the top of the inner cylinder 5 penetrates out of the outer cylinder 3 to be provided with a water return port;
the section of the water inlet pipe 4 is rectangular, and the water inlet pipe 4 is communicated with the side surface of the outer barrel 3;
the bottom of the outer cylinder 3 is provided with a conical cylinder 2, and the bottom of the conical cylinder 2 is provided with a water tank 1; the water tank 1 is provided with a sewage outlet for discharging concentrated sewage.
The sewage concentration device of the embodiment is mainly used for concentrating and separating the wastewater generated in the wet desulphurization process of industrial production, and the separated wastewater generates high-concentration sewage containing more pollutants and reclaimed water which can directly flow back to the wet desulphurization pipeline for recycling, so that the amount of the sewage needing to be filtered by the filter press 9 is reduced, and the operation energy consumption and the cost are reduced.
When the device is used, sewage enters from the water inlet pipe 4, and the water inlet pipe 4 is communicated with the side surface of the outer barrel 3, so that the sewage simultaneously moves downwards along the axial direction and outwards along the radial direction after entering, forms an outer rotational flow under the action of the power of the sewage, and rotates downwards to enter the conical barrel 2; in the embodiment, the diameter of the conical cylinder body 2 is sequentially reduced from top to bottom, so that the flow section of the sewage is gradually reduced along with the downward flow, the tangential flow speed of the sewage is continuously increased, the turbulent kinetic energy intensity of an internal flow field is increased, the concentration efficiency is improved, more reclaimed water can be separated, and the amount of sewage to be treated is further reduced.
When actually setting up, the length of taper cylinder 2 needs to be greater than urceolus 3, this because the whole height of device is limited in the actual production process, and extension taper cylinder 2 length is favorable to improving the sewage separation path with higher speed, and then improves concentration efficiency. In this embodiment, the height of the tapered cylinder 2 is 1.5 times the height of the outer cylinder 3.
In this embodiment the height of the inlet conduit 4 is greater than the width of the inlet conduit 4. Further, the height of the inlet pipe 4 is 2 times the width. Thus, the falling rotating force can be generated conveniently, the sewage can rotate at high speed in the outer cylinder 3, and the separation efficiency is improved.
When the device of the embodiment is arranged, the interface between the water inlet pipe 4 and the outer cylinder 3 is higher than the inlet at the bottom of the inner cylinder 5. This prevents the contaminated water entering the outer tub 3 from being directly discharged from the inner tub 5.
In the embodiment, the taper angle of the taper cylinder body 2 is 10-30 degrees. The angle range is most beneficial to the concentration of sewage, and can separate reclaimed water to the maximum extent.
As shown in fig. 3, another aspect of the present embodiment provides a sewage treatment system, including: a sewage tank 6 and the sewage concentration device; the sewage tank 6 is connected with the water inlet pipe 4. The sewage treatment system also comprises a dosing tank 7, and the water return port is connected with the dosing tank 7. The sewage outlet is connected with a filter press 9, and a sewage pump 8 is arranged between the filter press 9 and the sewage outlet.
When the treatment system is used, concentrated sewage treated by the sewage concentration device is pumped into a filter press 9 through a sewage pump 8 for filtration, and separated reclaimed water flows back to a dosing tank 7 for recycling. After the treatment system of this embodiment is used, can concentrate sewage to 20% of original volume, the 80% normal water of separation then need not pressure filter 9 and filters, can directly circulate back to adding in the medicine pond 7, has reduced the investment of sewage equipment 80% from this, only needs to carry out pressure filter 9 to 20% of original sewage volume and filters to play the purpose of using electricity wisely, reducing the energy consumption, reduce cost.
In a word, the utility model discloses a sewage concentration device can concentrate sewage, reduces the sewage volume that needs to be handled to reach energy saving and emission reduction's purpose.
