Description

Technical Field

[0001] The utility model relates to a water treatment system device in the field of environmental protection, in particular to a sludge dehydration treatment system device suitable for a desulfurization wastewater treatment system. Background Art

[0002] In the past, when the water ring vacuum pump equipped with the vacuum rotary dehydrator was working, the working fluid used was directly discharged, resulting in a large waste of water resources. Summary of the invention

[0003] Aiming at the defects of the existing vacuum rotary dehydrator system device, the utility model provides a novel vacuum rotary dehydrator system device, which has the characteristic that the working fluid of the water ring vacuum pump can be recycled.

[0004] The specific technical measures of the utility model are:

[0005] The vacuum rotary dehydrator is connected to the vacuum automatic drainer through pipeline I, the vacuum automatic drainer is connected to the vacuum pump through pipeline II, the exhaust port of the water ring vacuum pump is connected to the gas-liquid separator, the gas-liquid separator is connected to the heat exchanger through pipeline III, and the heat exchanger is connected to the water ring vacuum pump through pipeline IV.

[0006] The beneficial effect of the utility model is that the working fluid of the water ring vacuum pump can be recycled, which saves a lot of production water. Under the current condition that water resources are becoming increasingly scarce, the utility model has very important social significance and economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The utility model is further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0008] Figure 1 It is a schematic diagram of the system structure of the utility model and is also a summary diagram of the specification. DETAILED DESCRIPTION

[0009] The specific details and working conditions of the utility model are described below in conjunction with the accompanying drawings of the specification.

[0010] The utility model Figure 1 As shown, the vacuum rotary dehydrator 2 is connected to the vacuum automatic drainer 7 through the pipeline Ⅰ3, the vacuum automatic drainer 7 is connected to the water ring vacuum pump 15 through the pipeline Ⅱ13, the exhaust port of the water ring vacuum pump is connected to the gas-liquid separator 20, the gas-liquid separator 20 is connected to the heat exchanger 11 through the pipeline Ⅲ18, and the heat exchanger 11 is connected to the water ring vacuum pump 15 through the pipeline Ⅳ10.

[0011] The working condition of the utility model is as follows: the medium to be treated enters the vacuum rotary dehydrator 2 from the liquid inlet 1, and the intercepted mud cake is discharged from the mud outlet 5. The lower part of the vacuum rotary dehydrator 2 is provided with a sewage outlet 4 for sewage discharge. When the water ring vacuum pump 15 is working, the vacuum formed in the vacuum automatic drainer 7 sucks the filtrate from the pipeline Ⅰ3 into the vacuum automatic drainer 7, and the gas and liquid are separated in the vacuum automatic drainer 7. The gas is sucked into the vacuum pump 15 from the pipeline Ⅱ13, and the liquid is discharged from the bottom sewage outlet 6. A pressure transmitter 14 is provided on the vacuum automatic drainer 7 to control the vacuum degree. When the water ring vacuum pump 15 is working, working fluid needs to enter the water ring vacuum pump 15. Initially, the gas-liquid separator 20 is first filled with water to the high liquid level, and the automatic valve 21 is interlocked with the liquid level transmitter 16. When the gas-liquid separator 20 reaches the high liquid level, the automatic valve 21 is closed and the liquid intake is stopped. When the gas-liquid separator 20 reaches the low liquid level, the automatic valve 21 opens. The working fluid used by the water ring vacuum pump 15 flows from the gas-liquid separator 20 through the pipeline III 18 to the heat exchanger 11, then enters the water ring vacuum pump 15 through the pipeline IV 10, and then returns to the gas-liquid separator 20 through the pipeline V 17 from the exhaust port of the water ring vacuum pump 15. The gas-liquid separator 20 is provided with a sewage outlet 12 for emptying and overflowing. Since the working fluid temperature of the water ring vacuum pump 15 will increase when it is working, the water temperature needs to be reduced to a certain temperature before it can be recycled to avoid reducing the working efficiency of the water ring vacuum pump 15. The heat exchanger 11 is provided with a cooling water inlet 9 and an outlet 8.
