[0002] Steam boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in the fuel, electrical energy, thermal energy of high-temperature flue gas, etc., and after conversion by the boiler, steam with a certain amount of thermal energy is output. At present, energy utilization still has the main problems of low utilization efficiency, poor economic benefits, and great pressure on the ecological environment. Waste heat resources belong to secondary energy. The gas temperature generated in the heating furnace is generally around 120℃~350℃. There is a lot of heat in the water vapor generated by the combustion of the steam boiler. Recycling the huge amount of heat can achieve the effect of saving energy. If the heat cannot be effectively utilized, it will lead to a lot of heat waste.

[0003] After searching, for example, a Chinese patent document discloses a heat recovery system for a steam boiler [Application number: CN202122007543.4; Publication number: CN215863348U].

[0004] The recovery system disclosed in the patent performs heat exchange in a heat exchange box and performs heat exchange in a closed water tank, so the effect is better. However, during the long-term heat exchange work, the water vapor impacts the heat exchange pipe for a long time, and the minerals carried in the water vapor will adhere to the surface of the heat exchange pipe, forming a large area of ​​scale over a long period of time. The equipment cannot clean the scale on the surface of the water pipe, which affects the direct contact of the water vapor with the surface of the heat exchange pipe, resulting in a decrease in the efficiency of heat exchange and a decrease in the practicality of the entire device.

[0024] A method for using a heat energy recovery device based on an automatic control electric valve, the method comprising the following steps:

[0025] S1. When in use, turn on the water pump to extract external water through the water pump, and the external water enters the inner cavity of the heat exchange water pipe in the steam pipe body through the water inlet pipe. Then the staff sets the water temperature valve point through the control panel outside the water storage tank to control the temperature of the water in the heat exchange water pipe when it enters the water storage tank. When the water temperature reaches the appropriate temperature, the temperature module opens the electric valve to allow the water in the heat exchange water pipe to enter the water storage tank. If the water in the water storage tank is used, the electric valve on the second water outlet pipe is opened, and the water in the water storage tank can also enter the heat exchange water pipe through the water inlet pipe through the return pipe to re-circulate and heat;

[0026] S2. When water vapor impacts the heat exchange water pipe for a long time, a certain amount of scale will be generated on the surface of the heat exchange water pipe, which will affect the use of the heat exchange water pipe and cause the heat exchange efficiency to decrease. The staff uses the second hydraulic rod to drive the connecting piece to move, and moves the upper extension plate downward, and moves the lower extension plate upward, opens the corresponding upper opening and lower opening, and makes the second slot of the second chassis communicate with the lower opening, and makes the first slot of the first chassis communicate with the upper opening. The staff can use the power mechanism to provide power to the spraying mechanism and the recovery mechanism, turns on the first motor in the power mechanism, and the first motor drives the active bevel gear and the driven bevel gear to rotate, and the power roller located in the inner cavity of the driven bevel gear drives the first gear and the second gear to rotate, and the first rack meshing with the first gear moves, and the first slider and the first slide groove are connected. Under the limit, the metal ring tube is driven to move into the inner cavity of the steam pipe body, and under the action of the tube reel body, the external solution hose is released to a corresponding length, and the metal ring tube is above the heat exchange water pipe, at this time, the external aqueous solution is transmitted, and the external aqueous solution reaches the metal ring tube through the external solution hose, and finally, under the action of the spray head, the aqueous solution is sprayed on the heat exchange water pipe, and at the same time, the second rack meshing with the second gear also moves, and under the restriction of the second slide groove and the second slider, the second rack drives the recovery box to move into the inner cavity of the steam pipe body, and the recovery box receives the aqueous solution sprayed by the spraying mechanism and the scale dissolved by the aqueous solution, and uses the waste water pipe to discharge the waste water solution, and after the spraying mechanism has worked for a period of time, the spraying mechanism and the recovery mechanism are similarly recovered by the power mechanism;

[0027] S3. After the spraying mechanism and the recovery mechanism have finished working, the roller brush mechanism is used to clean the stubborn stains on the surface of the heat exchange water pipe, the second motor in the third chassis is turned on, the screw is driven to rotate by the operation of the second motor, and the threaded sleeve limited by the telescopic rod begins to move downward, and at the same time, the first hydraulic rod on the first support block is used to lower the output end of the first hydraulic rod, so that the height of the roller brush mechanism is reduced. Under the joint action of the first hydraulic rod and the screw, the brush rod reaches the specified position, and the third motor is turned on. Under the action of the third motor, the second connecting block connected to the third motor rotates, and drives the connecting rod and the brush rod to rotate, so as to clean the surface of the heat exchange water pipe. At this time, the forward and reverse rotation of the second motor can be controlled to control the up and down movement of the brush rod. After cleaning, the second motor and the first hydraulic rod are used to reset the roller brush mechanism;

[0028] S4. After the roller brush mechanism works, the power mechanism is turned on again, so that the metal ring tube and the recovery box on the spraying mechanism and the recovery mechanism enter the inner cavity of the steam pipe body again. At this time, clean water without chemical substances is sprayed through the external solution hose in the spraying mechanism to flush the heat exchange water pipe again, so that the scale and stubborn stains on the surface of the heat exchange water pipe are cleaned again. After the cleaning is completed, the metal ring tube and the recovery box on the spraying mechanism and the recovery mechanism are retracted through the power mechanism, and the upper and lower openings of the steam pipe body are closed by the second hydraulic rod. Then, the steam pipe body can continue to be used, and heat recovery can also be performed at the same time.

[0029] Compared with the prior art, the heat energy recovery device and method based on the automatic control electric valve has the following advantages:

[0030] 1. The present invention can not only spray the scale-dissolving solution on the heat exchange water pipe in the steam pipe body to dissolve the scale on the surface of the heat exchange water pipe, but also recover the sprayed aqueous solution while spraying to prevent the aqueous solution from entering the steam boiler along the steam pipe body. After spraying, the surface of the heat exchange water pipe can be cleaned to remove stubborn stains other than scale, thereby solving the problem that the heat exchange efficiency of the current steam boiler is affected by scale generated on the surface of the heat exchange pipe during heat recovery during heat exchange, and the cleaning solution is not easy to recover during the scale cleaning process.

[0031] 2. The present invention facilitates spraying descaling solution and clean water for cleaning on the surface of the heat exchange water pipe, transporting external aqueous solution through an external solution hose, and completing reciprocating motion with the help of a power mechanism.

[0032] 3. The present invention facilitates the recovery of the aqueous solution sprayed by the spraying mechanism, and prevents the aqueous solution from entering the combustion device through the steam pipe body over a large area, thereby causing certain impacts on the combustion device.

[0056] A method for using a heat energy recovery device based on an automatic control electric valve, the method comprising the following steps:

[0057] S1. This device adopts the heat exchange principle to perform heat exchange on the water vapor in the steam pipe body 1. When in use, turn on the water pump 5, extract the external water through the water pump 5, and the external water enters the inner cavity of the heat exchange water pipe 10 in the steam pipe body 1 through the water inlet pipe 2. Then the staff sets the water temperature valve point through the control panel 9 on the outside of the water storage tank 7 to control the temperature of the water in the heat exchange water pipe 10 when it enters the water storage tank 7. When the water temperature reaches the appropriate temperature, the temperature module 11 opens the electric valve 6 to allow the water in the heat exchange water pipe 10 to enter the water storage tank 7. If the water in the water storage tank 7 is used, the electric valve 6 on the second water outlet pipe 8 is opened, and the water in the water storage tank 7 can also enter the heat exchange water pipe 10 through the water inlet pipe 2 through the return pipe 30 to be recirculated and heated;

[0058] S2. When water vapor impacts the heat exchange water pipe 10 for a long time, a certain amount of scale will be generated on the surface of the heat exchange water pipe 10, which will affect the use of the heat exchange water pipe 10 and reduce the efficiency of heat exchange. The staff uses the second hydraulic rod 29 to drive the connecting piece 28 to move, and moves the upper extension plate 15 downward, and moves the lower extension plate 14 upward, opens the corresponding upper opening 13 and lower opening 12, and makes the second slot 25 of the second chassis 24 communicate with the lower opening 12, and makes the first slot 21 of the first chassis 20 communicate with the upper opening 13. The operator can use the power mechanism 23 to provide power to the spraying mechanism 22 and the recovery mechanism 26, turn on the first motor 2301 in the power mechanism 23, the first motor 2301 drives the active bevel gear 2302 and the driven bevel gear 2303 to rotate, and the power roller 2304 located in the inner cavity of the driven bevel gear 2303 drives the first gear 2206 and the second gear 2604 to rotate, the first rack 2204 meshing with the first gear 2206 moves, and the first slider 2202 and the first slide groove are connected. Under the limit of 2205, the metal ring tube 2207 is driven to move into the inner cavity of the steam pipe body 1, and under the action of the pipe reel body 2203, the external solution hose 2201 is released to a corresponding length, and the metal ring tube 2207 is above the heat exchange water pipe 10, at this time, the external aqueous solution is transmitted, and the external aqueous solution passes through the external solution hose 2201 to the metal ring tube 2207, and finally, under the action of the spray head 2208, the aqueous solution is sprayed on the heat exchange water pipe 10, and at the same time, the second gear 2604 is connected to the heat exchange water pipe 10. The meshed second rack 2603 also moves, and under the restriction of the second slide groove 2601 and the second slider 2602, the second rack 2603 drives the recovery box 2606 to move into the inner cavity of the steam pipe body 1, and the recovery box 2606 receives the aqueous solution sprayed by the spraying mechanism 22 and the scale dissolved by the aqueous solution, and uses the waste water pipe 2605 to discharge the waste water solution. After the spraying mechanism 22 works for a period of time, the spraying mechanism 22 and the recovery mechanism 26 are similarly recovered by the power mechanism 23;

[0059] S3. After the spraying mechanism 22 and the recovery mechanism 26 have finished working, the roller brush mechanism 19 is used to clean the stubborn stains on the surface of the heat exchange water pipe 10. The second motor 1902 in the third case 18 is turned on. The screw 1903 is driven to rotate by the second motor 1902, and the threaded sleeve 1904 restricted by the telescopic rod 1910 starts to move downward. At the same time, the first hydraulic rod 4 on the first support block 16 is used to lower the output end of the first hydraulic rod 4, so that the height of the roller brush mechanism 19 is reduced. 1903, the brush rod 1908 reaches the specified position and turns on the third motor 1905. Under the action of the third motor 1905, the second connecting block 1906 connected to the third motor 1905 rotates, and drives the connecting rod 1907 and the brush rod 1908 to rotate, so as to clean the surface of the heat exchange water pipe 10. At this time, the forward and reverse rotation of the second motor 1902 can be controlled to control the up and down movement of the brush rod 1908. After cleaning, the second motor 1902 and the first hydraulic rod 4 are used to reset the roller brush mechanism 19;

[0060] S4. After the roller brush mechanism 19 works, the power mechanism 23 is turned on again, so that the metal ring tube 2207 and the recovery box 2606 on the spraying mechanism 22 and the recovery mechanism 26 enter the inner cavity of the steam pipe body 1 again. At this time, clean water without chemical substances is sprayed through the external solution hose 2201 in the spraying mechanism 22 to flush the heat exchange water pipe 10 again, so that the scale and stubborn stains on the surface of the heat exchange water pipe 10 are cleaned again. After the cleaning is completed, the metal ring tube 2207 and the recovery box 2606 on the spraying mechanism 22 and the recovery mechanism 26 are retracted through the power mechanism 23, and the second hydraulic rod 29 is used to make the upper plate 15 and the lower plate 14 close the upper opening 13 and the lower opening 12 of the steam pipe body 1, so that the steam pipe body 1 can continue to be used, and heat recovery can also be performed at the same time.
