Description

Technical Field

[0002] The heat recovery unit condenser is a key device used in energy recovery systems. It is commonly used in industrial and commercial buildings to maximize the use of exhaust heat and save energy. The condenser is a component of the heat recovery unit, used to condense the waste heat in the heat recovery system into usable thermal energy. The heat recovery unit extracts waste heat from the heating, cooling or production process and converts it into high-temperature water vapor or steam in the condenser. This heat energy can be used for other applications such as heating, producing hot water or generating electricity.

[0003] A public announcement (publication) number CN221859345U discloses a heat recovery unit condenser. This technology discloses "including a condenser and an inlet and outlet water pipe, the inlet and outlet water pipes are provided on the right side of the condenser, a mixing box is provided at the top of the inlet and outlet water pipes, and a first connecting pipe is provided inside the top of the mixing box, etc., which has the technical effect of flushing water stains in the condensation pipe with a cleaning agent."

Under the action of one-way valve 1, one-way valve 2, one-way valve 3 and one-way valve 4, the cleaning liquid is ensured to flow along the predetermined path. The reciprocating movement of the round piston changes the internal pressure of the round barrel 2, so that the cleaning liquid is repeatedly flushed in the condenser. The mechanical force generated by the flow of the agent can effectively peel off the loose scale particles, and at the same time continuously update the contact interface, allowing the agent to continue to react with the scale layer, strengthening the cleaning of dead corners, and significantly improving the flushing effect of the condenser scale, ensuring that the inside of the condenser is comprehensively and thoroughly cleaned.

When the cleaning fluid flows inside the fourth pipe, the spiral blade drives the rotating shaft to rotate, thereby causing the bent rod and the scraper rod to rotate synchronously. The scraper rod rotates in accordance with the surface of the filter, scraping the trapped debris into the guide trough and flowing into the space between the outer ring and the inner ring to avoid the accumulation of debris affecting the filtration efficiency of the filter, thereby ensuring the continuity and efficiency of the cleaning fluid filtration. The ring filter intercepts and stores the debris, allowing the moisture on the surface of the debris to flow back to the barrel one, so that the cleaning fluid after filtering the debris can flow back to the condenser, avoiding the accumulation of scale cleaned inside the condenser and ensuring the cleaning effect of the condenser. Pulling up the second connecting rod can easily remove the outer ring and the inner ring, making it easy to clean the trapped debris and improving maintenance convenience.

[0021] 3. A pressure regulating component is provided to realize dynamic adjustment of the flow rate of the cleaning liquid and enhance the cleaning effect. The motor drives the disc and the optical axis to rotate. The optical axis cooperates with the U-shaped rod to make the card plate drive the circular piston to move back and forth. The interaction between the optical axis and the lever changes the reciprocating rotation rate of the U-shaped rod, thereby changing the reciprocating movement rate range of the card plate and the circular piston, and finally changing the flow rate range of the cleaning liquid inside the condenser tube, that is, the flow rate of the cleaning liquid inside the condenser tube is constantly changing. Different flow rates can adapt to scales of different stubbornness. High-speed flow can strongly flush stubborn scales, and low-speed flow can carefully clean dead corners, further improving the flushing effect of scale on the condenser tube, meeting diverse cleaning needs, and ensuring the efficiency and thoroughness of condenser tube cleaning.

[0053] Working principle: The circular cover 2 is installed with an inlet and outlet water pipe on the side away from the condenser body 1, and the inlet and outlet water pipes are blocked by the middle partition 6. When it is necessary to clean the water stains in the condenser pipe of the heat recovery unit condenser, first close the inlet and outlet water pipes on the circular cover 2, then connect one end of pipe 1 38 to one end of valve 1 36, connect one end of pipe 3 310 to valve 2 37, open valve 1 36 and valve 2 37, connect one end of valve 3 316 to the cleaning liquid storage barrel through the pipe, open valve 3 316 and inject cleaning liquid into the interior of barrel 2 33;

[0054] Under the action of the one-way valve 4 315, the liquid inside the second barrel 33 can flow along the inside of the first pipe 38 into the inside of the circular cover 2, and the flow direction is irreversible. Under the action of the one-way valve 314, the liquid inside the first pipe 38 can flow along the inside of the second pipe 39 into the inside of the second barrel 33, and the flow direction is irreversible. Under the action of the one-way valve 1 312, the liquid inside the first barrel 32 can flow along the inside of the third pipe 310 into the inside of the circular cover 2, and the flow direction is irreversible. Under the action of the one-way valve 2 313, the liquid inside the third pipe 310 can flow along the inside of the fourth pipe 311 into the inside of the first barrel 32, and the flow direction is irreversible.

[0055] As the cleaning liquid is injected into the second barrel 33 through the third valve 316, the cleaning liquid inside the second barrel 33 flows along the first pipe 38 into the interior of the circular cover 2 under the action of hydraulic pressure, passes through the condenser tube of the condenser body 1, and flows from the third pipe 310 into the fourth pipe 311, and then flows from the fourth pipe 311 into the interior of the first barrel 32. After the liquid level inside the first barrel 32 reaches a suitable level, the third valve 316 is closed.

[0056] By connecting the motor 57 to an external power source, the operation of the motor 57 drives the disc 58 to rotate, the rotation of the disc 58 drives the optical axis 59 to rotate, and the rotation of the optical axis 59 drives the U-shaped rod 56 to reciprocate inside the side plate 55. During this process, under the action of the gravity of the weight block 52, the position between the L-shaped sleeve 51 and the insertion rod 515 does not change. The reciprocating movement of the U-shaped rod 56 causes the connecting shaft 510 to slide inside the U-shaped rod 56, that is, the clamping plate 35 reciprocates inside the square sleeve 513. The reciprocating movement of the clamping plate 35 drives the round piston 34 to reciprocate synchronously.

[0057] When the round piston 34 moves upward, the movement of the round piston 34 increases the negative pressure inside the barrel 2 33, so that the cleaning liquid inside the condenser flows along the inside of the pipe 1 38 into the inside of the pipe 2 39, and flows from the inside of the pipe 2 39 into the inside of the barrel 2 33. At this time, the cleaning liquid inside the barrel 1 32 flows into the condenser along the inside of the pipe 3 310. When the round piston 34 moves downward, the cleaning liquid inside the barrel 2 33 flows into the condenser along the inside of the pipe 1 38, and flows into the inside of the pipe 4 311 along the pipe 3 310, and flows from the pipe 4 The top of 311 flows into the interior of barrel 1 32. In the process of the liquid in barrel 2 33 passing through pipe 1 38 and flowing into the condenser, the pipe filter 418 can filter the cleaning liquid flowing into the condenser from the interior of pipe 1 38, thereby filtering out the dirt in the cleaning liquid. By making the cleaning liquid flow back and forth in the condenser, the mechanical force generated by the flow of the agent can peel off the loose scale particles. The reciprocating flow of the cleaning liquid increases the flushing effect of the scale, and at the same time continuously updates the contact interface, so that the agent continues to react with the scale layer and strengthens the cleaning of dead corners.

[0058] When the motor 57 drives the optical axis 59 to rotate, when the optical axis 59 rotates to contact the lever 512, the rotation of the optical axis 59 drives the lever 512 to move, and the movement of the lever 512 drives the L-shaped sleeve 51 to slide on the surface of the insertion rod 515 through the L-shaped rod 511. At this time, the movement of the L-shaped sleeve 51 pulls the weight block 52 upward through the pull rope 53. In the process of the L-shaped sleeve 51 sliding on the surface of the insertion rod 515, it drives the side plate 55 to move synchronously. The movement of the side plate 55 drives one end of the U-shaped rod 56 to move. As the optical axis 59 rotates, when the height of the optical axis 59 is higher than the top of the lever 512, the L-shaped sleeve 51 slides quickly on the surface of the insertion rod 515 under the action of the gravity of the weight block 52, so that the optical axis 59 drives the lever 512 to move again. In the process of the reciprocating rotation of the U-shaped rod 56 driven by the rotation of the optical axis 59, the U-shaped rod 56 will rotate reciprocatingly. The speed of the cleaning fluid is constantly changing, and when the rotation of the optical axis 59 drives the U-shaped rod 56 to move back and forth, the position of the side plate 55 is changed, thereby changing the speed change range of the reciprocating rotation of the U-shaped rod 56, thereby achieving the effect of changing the reciprocating speed range of the card plate 35. The change in the speed range of the reciprocating movement of the card plate 35 causes the reciprocating speed range of the round piston 34 to change, thereby changing the flow rate range of the cleaning fluid inside the condenser tube, thereby further increasing the effect of flushing the scale on the condenser tube, and achieving the change in the flow rate range of the cleaning fluid inside the condenser tube, that is, the flow rate of the cleaning fluid inside the condenser tube is constantly changing, and different flow rates can adapt to scales of different stubbornness. High-speed flow can strongly flush stubborn scales, and low-speed flow can carefully clean dead corners, further improving the flushing effect of the condenser tube scale, meeting diverse cleaning needs, and ensuring the efficiency and thoroughness of condenser tube cleaning;

[0059] The cleaning liquid flowing from the inside of the pipe four 311 to the inside of the drum one 32 flows to the surface of the filter 41 under the action of the top cover 410. Under the action of the filter 41, the debris in the cleaning liquid is filtered, and the trapped debris adheres to the surface of the filter 41. During the flow of the cleaning liquid inside the pipe four 311, the spiral blade 47 drives the rotating shaft 46 to rotate. The rotation of the rotating shaft 46 drives the curved rod 48 and the scraper rod 49 to rotate synchronously. The scraper rod 49 is arc-shaped, and the scraper rod 49 adheres to the surface of the filter 41 and rotates, thereby scraping the debris on the surface of the filter 41 into the inside of the guide trough 417 and flowing into the space between the outer ring 412 and the inner ring 415, which is beneficial. When the cleaning liquid flows from the inside of the fourth pipe 311, the scraper rod 49 scrapes away the debris on the surface of the filter 41, thereby ensuring the efficiency of the filter 41 in filtering the cleaning liquid. Under the action of the annular filter 413, the debris can be intercepted and stored. The water on the surface of the debris passes through the annular filter 413 and flows into the inside of the drum 1 32 along the inside of the annular groove 411, so that the cleaning liquid after filtering the debris is stored in the inside of the drum 1 32. The cleaning liquid in the drum 1 32 that has filtered the debris can flow back to the condenser along the inside of the third pipe 310, thereby ensuring the cleaning effect of the condenser and preventing the scale cleaned from the inside of the condenser from accumulating in the condenser, causing cleaning inconvenience.

[0060] After the condenser tube is cleaned, the second connecting rod 414 is pulled upward to make the outer ring 412 and the inner ring 415 slide out from the inside of the ring groove 411, thereby facilitating the cleaning of debris trapped between the outer ring 412 and the inner ring 415.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
