Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater discharge device for chemical environmental protection. Background Technology

[0002] Pure water undergoes changes in its original physical or chemical properties after use, becoming wastewater containing various impurities. Chemical wastewater includes process wastewater, cooling water, exhaust gas scrubbing water, equipment and site washing water, etc., discharged during chemical production. If this wastewater is discharged without treatment, it will cause different properties and degrees of pollution to water bodies, thereby endangering human health and affecting industrial and agricultural production.

[0003] Currently, it is common for chemical wastewater to be sometimes highly acidic and sometimes highly alkaline, which poses a great threat to organisms, buildings, and crops. During the neutralization process of wastewater, the rising water vapor generated by the heat release can carry small amounts of acidic liquid, alkaline liquid, or other impurity particles, which then adhere to the inner wall of the equipment, causing corrosion or impurity accumulation and seriously affecting the service life of the wastewater treatment equipment. Utility Model Content

[0004] To address the problems of frequent maintenance, short service life, and low efficiency in chemical wastewater treatment equipment, this utility model provides a wastewater discharge device for chemical environmental protection, and the technical solution adopted is as follows:

[0006] The tank body has an inlet pipe and an outlet pipe connected to its top and bottom, respectively. The outlet pipe is equipped with a first electromagnetic switch valve, and the tank body is also equipped with an acid-base sensor.

[0007] The storage tank is connected to the upper part of the tank body via a transmission pipe, and a second electromagnetic switch valve is installed on the transmission pipe.

[0008] A shaft is coaxially disposed inside the tank, and a support ring is sleeved on the outer wall of the shaft. Multiple sets of stirring blades are fixedly connected to the outside of the support ring.

[0009] The drive motor is connected to the shaft drive and is used to drive the shaft to rotate;

[0010] A condenser is disposed at the upper end of the tank body;

[0011] The control box contains a controller. The controller's signal input terminal is connected to the pH sensor, and its signal output terminal is connected to the first electromagnetic switch valve and the second electromagnetic switch valve.

[0012] Preferably, the storage tank is provided in two sets, with the two sets of storage tanks located on both sides of the tank body and containing acidic liquid and alkaline liquid respectively.

[0013] Preferably, the tank body consists of an upper shell and a lower shell, and an annular mounting plate is fixedly connected to the lower end of both the upper shell and the lower shell. The two annular mounting plates are detachably and fixedly connected by bolts and nuts.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The acidity or alkalinity of the wastewater is detected by a pH sensor and the corresponding acidic or alkaline liquid is added under the control of a controller. The wastewater is then neutralized by a stirring device, which effectively improves the wastewater treatment efficiency and effect.

[0019] 2. A condenser is installed in the upper part of the tank to quickly cool the water vapor generated during the neutralization process of sewage and let the condensed water droplets fall back into the liquid.

[0026] like Figure 1 and Figure 2As shown, a wastewater discharge device for chemical environmental protection includes a tank 8, a storage tank 3, a shaft 12, and a control box 10. Support legs 9 are fixedly connected to the bottom of the tank 8. An inlet pipe 1 and an outlet pipe 11 are connected to the top and bottom of the tank 8, respectively. The storage tank 3 is connected to the upper part of the tank 8 via a transmission pipe 4. A first electromagnetic valve 14 is installed on the outlet pipe 11, and a second electromagnetic valve 5 is installed on the transmission pipe 4. The shaft 12 is coaxially arranged inside the tank 8. Multiple sets of support rings 17 are coaxially welded to the outside of the shaft 12, and these support rings are evenly spaced along the axial direction of the shaft 12. Multiple sets of stirring blades 13 are welded to the outside of the support rings 17 in a circumferential direction. Furthermore, a drive motor 2 is fixedly connected to the top of the tank 8, and the output shaft of the drive motor 2 is coaxial with the shaft 12. The drive motor 2 is fixedly connected, and its rotation can drive the shaft 12, stirring blade 13, and support ring 17 to rotate. The tank body 8 is also equipped with an acid-base sensor 18 and a condenser 19. The acid-base sensor 18 is located in the lower part of the tank body 8 and is used to detect the acid-base value of the liquid inside the tank body 8. The condenser 19 is fixedly connected to the upper part of the tank body 8. The cooling medium inlet pipe and return pipe of the condenser 19 both pass through the tank body 8 and are connected to the condenser 19. The control box 10 is fixedly connected to the outside of the support leg 9. The control box 10 is equipped with a controller 15 and a data storage device 16. The acid-base sensor 18 is connected to the signal input terminal of the controller 15. The first electromagnetic switch valve 14 and the second electromagnetic switch valve 5 are both connected to the signal output terminal of the controller 15.

[0027] The tank body 8 consists of an upper shell and a lower shell. The lower end of the upper shell and the upper end of the lower shell are respectively fixedly connected to a first annular mounting plate 6 and a second annular mounting plate 7. The first annular mounting plate 6 and the second annular mounting plate 7 are provided with mounting holes distributed in corresponding positions. The two are detachably fixedly connected by bolts and nuts, which facilitates the cleaning and maintenance of the inner wall of the tank body 8.

[0028] There are two sets of storage tanks 3, located on the left and right sides of the upper part of the tank body 8 respectively. The left storage tank 3 contains acidic liquid, and the right storage tank 3 contains acidic liquid.

[0029] The lower end face of the condenser 19 is designed as a non-flat structure. Specifically, the lower end face of the condenser 19 is provided with multiple sets of evenly distributed protrusions, which are inverted conical in shape. Moreover, the lower end face of the condenser 19 is coated with an anti-corrosion layer, which is made of ZS-1034 acid and alkali resistant anti-corrosion coating. Water vapor generated during the neutralization of sewage with acidic or alkaline liquids can be cooled by the condenser 19 and condensed into the inside of the tank 8. This avoids water vapor mixed with acidic, alkaline or impurity particles adhering to the inner wall of the tank 8, reducing the number of maintenance times for the tank 8 and improving its service life. Furthermore, the inverted conical protrusion structure at the lower end of the condenser 19 allows the water droplets after heat exchange to fall quickly into the liquid inside the tank 8, further reducing the flow of water vapor to the inner wall of the tank 8.

[0030] The working principle of this device is as follows:

[0031] Wastewater enters tank 8 through inlet pipe 1. The pH value of the wastewater is transmitted to controller 15 via pH sensor 18 inside tank 8. Controller 15 compares the detected data with preset pH standard values ​​stored in data memory 16. If the alkalinity exceeds the standard value, controller 14 will open the second solenoid valve 5 on the left, allowing acidic liquid to enter tank 8. Simultaneously, drive motor 2 operates, stirring the water in tank 8 via stirring blades 13, rapidly mixing the newly entered acidic liquid with the wastewater. If the pH of the liquid inside tank 8 is detected... When the vertical position is within the standard value range, the controller 15 will control the second electromagnetic switch valve 5 on the left to close; if the acidic liquid exceeds the standard, the second electromagnetic switch valve 5 on the right will open, and the operation steps are the same. In this way, automatic sewage treatment can be achieved, and the acidity and alkalinity of the sewage can meet the safety standards. The water vapor generated during the neutralization process of sewage is rapidly cooled by the condenser 19 and forms water droplets that fall into the liquid, effectively preventing water vapor from carrying acidic or alkaline liquids or other impurities and adhering to the inner wall of the tank 8. While improving the sewage treatment effect, it also effectively improves the service life of the tank.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
