Description

Technical Field

[0001] The utility model relates to the technical field of boiler equipment, in particular to an acidity neutralization device for recovering boiler condensate water. Background Art

[0002] Condensate recovery devices are used to recover condensed water generated in various steam-water heat exchangers or production processes. Condensed water is high-quality water and contains a large amount of thermal energy. Therefore, recovering condensed water in steam heating systems is one of the important measures for energy and water conservation. In order to avoid excessive acidity of the condensed water return water collected inside the water storage pipe of the condensed water recovery machine, which causes internal corrosion and scaling of the boiler, the condensed water return water inside the water storage pipe needs to be treated for acidity neutralization.

[0003] According to a publicly disclosed acidity neutralization device for boiler condensate recovery (publication number: CN219449444U), the above application uses a detection box and a pH detector to detect the pH value of the neutralized liquid. When the test is qualified, the liquid can be exported through the export pipe. When the test is unqualified, the liquid can be re-introduced into the neutralization chamber through the circulation pipe for neutralization again, thereby ensuring the pH of the last exported liquid is qualified, while reducing the layout of the pH detector and reducing costs.

[0004] However, during the actual use of the above-mentioned equipment, after the pH detector detects the liquid entering the detection box, a small amount of liquid will remain inside the detection part at the upper end of the pH detector because the detection part of the pH detector is mostly set with a special-shaped structure for the convenience of centralizing the liquid. When the next time the liquid enters the detection box, this part of the residual liquid will affect the next test result, thereby affecting the final acidity neutralization effect of the condensate liquid. In view of this, we propose an acidity neutralization device for boiler condensate recovery. Summary of the invention

[0024] like Figure 1-Figure 5As shown, the utility model provides a technical solution: an acidity neutralization device for recovering boiler condensate, comprising a neutralization tank 1, condensate can enter the neutralization tank 1 through the water inlet at the upper end of the neutralization tank 1, a neutralization liquid pipe 2 is fixedly installed on the right surface of the neutralization tank 1, and neutralization liquid can enter the neutralization tank 1 through the neutralization liquid pipe 2 to neutralize the acidity of the condensate, a detection box 3 is fixedly installed on the bottom of the neutralization tank 1 through a connecting pipe, an electromagnetic valve is arranged on the outside of the connecting pipe, and whether the liquid in the neutralization tank 1 enters the detection box 3 through the connecting pipe, a pH detector 4 is fixedly installed on the inner bottom surface of the detection box 3, and the pH detector 4 The pH value of the liquid entering the detection box 3 can be tested. A circulation pipe 5 is fixedly installed on the left surface of the neutralization tank 1, and a circulation pump is arranged on the outside of the circulation pipe 5. The interior of the neutralization tank 1 is connected with the interior of the detection box 3 through the circulation pipe 5. When the liquid entering the detection box 3 is found to be unqualified, the circulation pump can be started to transport the unqualified liquid back to the interior of the detection box 3. A discharge pipe is fixedly installed on the bottom of the detection box 3, and an electromagnetic valve is also arranged on the outside of the discharge pipe. When the pH value detected by the pH detector 4 is qualified, the electromagnetic valve on the outside of the discharge pipe can be started to discharge the liquid. A cleaning component is arranged above the detection box 3.

[0025] The cleaning assembly includes: a through slot 601, a vertical electric push rod 602 and an electromagnet 605. The through slot 601 is opened on the upper surface of the detection box 3. The vertical electric push rod 602 is fixedly installed on the bottom surface of the neutralization tank 1. A water tank 603 is fixedly installed at the bottom end of the vertical electric push rod 602. When the vertical electric push rod 602 is started, it can drive the water tank 603 to move downward through the through slot 601 and enter the interior of the detection box 3. The size of the water tank 603 is compatible with the size of the through slot 601, and the water tank 603 is located directly above the PH detector 4.

[0026] A nozzle 604 is fixedly installed on the bottom surface of the water tank 603. The nozzle 604 is an inclined structure. The nozzle 604 is connected to the interior of the water tank 603. When the water tank 603 enters the interior of the detection box 3 and reaches the top of the PH detector 4, the nozzle 604 can be started to extract clean water from the inside of the water tank 603 to clean the upper detection part of the PH detector 4, and wash away the liquid remaining on the surface of the detection part during the last liquid detection. At the same time, since the nozzle 604 is an inclined structure and is located on the outside of the sponge block 609, as the sponge block 609 moves downward and enters the upper end of the PH detector 4, the nozzle 604 will not affect the movement of the sponge block 609.

[0027] The electromagnet 605 is fixedly installed at the center of the bottom surface of the water tank 603. A fixing plate 606 is fixedly installed at the bottom of the electromagnet 605. A guide groove 607 is provided on the bottom surface of the fixing plate 606. A connecting block 608 is slidably connected inside the guide groove 607. The connecting block 608 is made of square iron material. The upper surface of the connecting block 608 is in contact with the bottom surface of the electromagnet 605. A sponge block 609 is fixedly installed at the bottom end of the connecting block 608. The size of the sponge block 609 is adapted to the upper end of the pH detector 4.

[0028] The internal space at the upper end of the pH detector 4 is similar to a cross cavity. Only when the position of the sponge block 609 is matched with the upper end of the pH detector 4 can the interior of the detection part be entered. When the staff inserts the connecting block 608 into the guide groove 607, no matter which surface of the connecting block 608 is used, the sponge block 609 can be moved to a position that matches the upper end of the pH detector 4, which reduces the difficulty of installation. Subsequently, the electromagnet 605 can be energized to generate magnetic force to magnetically fix the connecting block 608. When the vertical electric push rod 602 is started to drive the water tank 603 to move downward, the sponge block 609 will be driven to move synchronously. After flushing the upper end of the pH detector 4, the vertical electric push rod 602 can be started again to drive the sponge block 609 to move downward into the upper end of the pH detector 4 to absorb the residual liquid therein to prevent the residual liquid from the last detection from affecting the next detection result.

[0029] An L-shaped fixing frame 701 is fixedly installed on the right surface of the detection box 3, and a transverse electric push rod 702 is fixedly installed on the right inner wall surface of the L-shaped fixing frame 701. A sealing plate 703 is fixedly installed on the left end of the transverse electric push rod 702. The left end of the sealing plate 703 passes through the right surface of the detection box 3, and the upper surface of the sealing plate 703 is in contact with the inner top surface of the detection box 3. When the transverse electric push rod 702 is started, it can drive the sealing plate 703 to move linearly in the left and right directions. When the sealing plate 703 moves to the left, the through groove 601 can be sealed to prevent dust and impurities in the outside air from entering the interior of the detection box 3 and affecting the detection results and the purity of the liquid.

[0030] In the present invention, when in use, after the liquid enters the detection box 3 for detection and is subsequently discharged or returned to the neutralization tank 1, the horizontal electric push rod 702 can be started to drive the sealing plate 703 to move to the right to open the through slot 601, and then the vertical electric push rod 602 is started to drive the water tank 603 to move downward. When it moves to the upper end of the PH detector 4, it stops moving, and the nozzle 604 is started to spray water to clean the detection part at the upper end of the PH detector 4. After cleaning, the vertical electric push rod 602 is continued to be started to move downward to drive the sponge block 609 to enter the PH detection The residual liquid inside the detection part at the upper end of the instrument 4 is absorbed to prevent the residual liquid from the previous detection from affecting the result of the next detection. After cleaning, the vertical electric push rod 602 is started to reset. After the water tank 603 leaves the inside of the detection box 3, the electromagnet 605 can be powered off, and the connection block 608 and the sponge block 609 can be released to replace the new sponge block 609. Through the cooperation of the fixing plate 606, the guide groove 607 and the connection block 608, the sponge block 609 can be guided and limited during installation, so that the sponge block 609 can be accurately moved to the required angle and position.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
