DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: Figures 1-6 As shown, the present invention provides a technical solution for a bathing room with composite waste heat recovery and utilization, which is characterized in that: the bathing room with composite waste heat recovery and utilization includes a base 1, on which a bathing room 2, a heat exchange box 3, and a heating element 4 are installed, a water storage layer 9 is opened on the base 1, and the water storage layer 9 is located below the bathing room 2, the heat exchange box 3 and the water storage layer 9 are connected through a heat exchange pump 10 and a filter component 11, the heating element 4 and the heat exchange box 3 are connected through a water supply pump 5, a heat exchange inner tube 6 is installed in the heat exchange box 3, the heat exchange outlet 8 on the heat exchange inner tube 6 is connected to the heating element 4 through a water inlet pipe 12, and the heat exchange inlet 7 on the heat exchange inner tube 6 is fed with normal temperature bathing water.

[0021] When the bathing room 2 is in use, the water supply pump 5 and the heat exchange pump 10 are started, and the waste water generated by bathing will flow into the water storage layer 9 through the sewer pipe. The heat exchange pump 10 pumps the hot waste water into the heat exchange box 3. At the same time, the water supply pump 5 pumps normal temperature water into the heating element 4. The normal temperature water flows through the heat exchange inner tube 6 and then flows into the heating element 4 for heating, and finally enters the bathing room for bathing. When flowing through the heat exchange box 3, the normal temperature water will exchange heat with the waste hot water through the heat exchange inner tube 6. The waste hot water can preheat the normal temperature bathing water, and the heat energy in the waste hot water can be recycled to save resources and reduce costs.

[0022] like Figure 4 As shown, a diverter pipe 13 is installed above the heat exchange box 3 , and a plurality of small holes are evenly distributed on the diverter pipe 13 . The diverter pipe 13 is connected to the output port of the filter assembly 11 .

[0023] The waste hot water flows to the heat exchange inner tube 6 through the small holes on the shunt pipe 13 when entering the heat exchange box 3, which can ensure the uniform distribution of the waste hot water in the heat exchange box 3, effectively improve the heat exchange efficiency, and further improve the waste heat utilization rate.

[0024] As shown in Figures 1-7 The heat exchange box 3 is provided with a baffle 22, the baffle 22 is connected with the bottom of the heat exchange box 3 through a slow flow plate 15, a plurality of slow flow holes 16 are uniformly arranged on the slow flow plate 15, an air outlet valve 20 is arranged on the heat exchange box 3, the air outlet valve 20 is located between the baffle 22 and the bottom of the heat exchange box 3, an air inlet 14 is arranged on the heat exchange box 3, an air outlet 17 is arranged on the upper part of the bathing room 2, the air outlet 17 and the air inlet 14 are connected through an air pipe 18, and an exhaust fan 19 is arranged at the air outlet 17.

[0025] When the bathing room 2 is used, the exhaust fan 19 is opened to exhaust the waste hot air generated into the lower part of the baffle 22 in the heat exchange box 3 through the air pipe 18, the temperature of the waste hot air is higher than that of the normal temperature water, and in the heat exchange box 3, the normal temperature water can also absorb the heat energy in the waste hot air through the heat exchange inner tube 6, further improving the waste heat recovery of the whole bathing room, realizing the combined recovery of the heat energy in the waste hot water and the waste hot air, further saving energy and reducing cost; when the waste hot air enters the heat exchange box 3, the waste hot air cannot be directly exhausted from the air outlet valve 20 under the obstruction of the slow flow plate 15, and the waste hot air can slowly blow the air outlet valve 20 through the slow flow holes 16, which can effectively prolong the residence time of the waste hot air in the heat exchange box 3 and improve the heat exchange efficiency of the waste hot air and the normal temperature water.

[0026] The filter assembly 11 is driven by the waste water pumped out by the heat exchange pump 10, and the heat exchange box 3 is provided with an adjusting assembly 21 which is driven by the temperature difference between the waste water in the heat exchange box 3 and the outside.

[0027] As shown in Figures 1-9 and Figures 9-10 The filter assembly 11 comprises a mounting frame 1101, a filter cylinder 1102, a bottom cover 1103, a filter plate 1109 and a connecting pipe 1113. The heat exchange box 3 of the bathing room 2 is connected through the mounting frame 1101, the mounting frame 1101 is provided with the filter cylinder 1102, the output end of the heat exchange pump 10 extends into the filter cylinder 1102, the bottom cover 1103 is arranged at the lower end of the filter cylinder 1102, the filter plate 1109 is arranged in the filter cylinder 1102, the bottom cover 1103 is connected with the shunt pipe 13 through the connecting pipe 1113, and the bottom end of the bottom cover 1103 is higher than the shunt pipe 13.

[0028] The bathing wastewater carries dirt and sundries. When the dirt is transported into the heat exchange box 3, the dirt will adhere to the outer wall of the heat exchange inner tube 6, thereby reducing the heat exchange efficiency between the waste hot water and the normal temperature bathing water and damaging the heat exchange inner tube 6. Before the waste hot water enters the heat exchange box 3, the waste hot water flows through the filter plate 1109, so that the dirt in the waste hot water can be reduced, the heat exchange efficiency is ensured, and the service life of the heat exchange inner tube 6 is prolonged.

[0029] The filter assembly 11 comprises a ring-shaped water pipe 1104, a rotating rod 1105, a vane 1106, a connecting ring 1107, a flow guide cylinder 1108, a transmission rod 1110, a scraper 1111 and a dirt storage groove 1112. The connecting ring 1107 is mounted in the filter cylinder 1102, and the ring-shaped water pipe 1104 is mounted on the connecting ring 1107. The ring-shaped water pipe 1104 is connected with the output end of the heat exchange pump 10. The rotating rod 1105 is rotatably mounted on the filter cylinder 1102. The vane 1106 is mounted on the lower end of the rotating rod 1105. The vane 1106 extends into the ring-shaped water pipe 1104. The transmission rod 1110 is mounted below the rotating rod 1105. The scraper 1111 is mounted on the end of the transmission rod 1110. The lower end of the scraper 1111 is attached to the filter plate 1109. The dirt storage groove 1112 is formed in the filter plate 1109.

[0030] When the waste hot water flows through the ring-shaped water pipe 1104, the vane 1106 is impacted, and the vane 1106 rotates around the rotating rod 1105. The vane 1106 drives the scraper 1111 to remove the dirt on the upper surface of the filter plate 1109 through the rotating rod 1105 and the transmission rod 1110. The dirt falls into the dirt storage groove 1112 at the edge of the filter plate 1109, so that the dirt does not block the filter plate 1109 and affect the filtering efficiency of the waste hot water. Every time interval, the worker needs to disassemble the bottom cover 1103 to clean the waste in the dirt storage groove 1112, so that the filter assembly 11 can be continuously used.

[0031] As shown in Figure 4 and Figure 8 The adjusting assembly 21 comprises a water outlet 2101, an adjusting frame 2102, a mounting plate 2103, an electric telescopic rod 2104, a flow resistance block 2105, a through hole 2106, an adjusting cylinder 2107, a sliding rod 2108, a sensing bead 2109, a heat-sensitive gas 2110 and an adjusting rod 2111. The adjusting frame 2102 is installed on the partition plate 22, the mounting plate 2103 is installed in the adjusting frame 2102, the electric telescopic rod 2104 is installed below the mounting plate 2103, the flow resistance block 2105 is installed at the end of the electric telescopic rod 2104, the through hole 2106 is formed below the adjusting frame 2102, the water outlet 2101 is formed on the heat exchange box 3, the water outlet 2101 and the through hole 2106 are coaxial, the size of the flow resistance block 2105 is greater than that of the through hole 2106, the adjusting cylinder 2107 is installed above the adjusting frame 2102, the sensing beads 2109 are installed at both ends of the adjusting cylinder 2107, one sensing bead 2109 is in the heat exchange box 3, and the other sensing bead 2109 is exposed outside the heat exchange box 3, the sliding rod 2108 is slidably installed in the adjusting cylinder 2107, the heat-sensitive gas 2110 is filled between the sliding rod 2108 and the sensing bead 2109, and the adjusting rod 2111 is installed on the sliding rod 2108.

[0032] The adjusting assembly 21 further comprises the press switches 2112, and the three press switches 2112 are installed on the mounting plate 2103 and electrically connected with the electric telescopic rod 2104.

[0033] The sensing bead 2109 in the heat exchange box 3 senses the temperature of the waste hot water in the heat exchange box 3, the sensing bead 2109 outside the heat exchange box 3 senses the temperature of the outside environment to represent the temperature of the normal-temperature bathing water entering the heat exchange inner tube 6, in the initial state, the sliding rod 2108 is located at the side close to the outside of the heat exchange box 3 in the slidable range, the flow resistance block 2105 forms an obstruction to the through hole 2106, at this time, the waste hot water in the heat exchange box 3 is being heat-exchanged with the normal-temperature bathing water in the heat exchange inner tube 6, after a heat exchange time, the heat energy contained in the waste hot water is reduced, the temperature is lowered, the volume of the heat-sensitive gas 2110 close to the heat exchange box 3 is contracted, the sliding rod 2108 moves to the side close to the inside of the heat exchange box 3, and the sliding rod 2108 drives the adjusting rod 2111 to move synchronously when moving, when the adjusting rod 2111 touches the press switch 2112, the press switch 2112 controls the electric telescopic rod 2104 to contract, the electric telescopic rod 2104 drives the flow resistance block 2105 to cancel the obstruction to the through hole 2106, so that the waste water with the reduced temperature is discharged from the heat exchange box 3, the more the temperature of the waste hot water is reduced, the more complete the heat exchange is, the greater the amplitude of the movement of the adjusting rod 2111, and the three press switches 2112 control the electric telescopic rod 2104 to contract to different degrees, the farther away from the press switch 2112, the more the electric telescopic rod 2104 is controlled to contract, so that the temperature reduction of the waste hot water controls the discharge speed of the waste water, the heat carried by the discharged waste water can be reduced, the heat exchange efficiency is improved, energy is further saved, and the cost is reduced.

[0034] The heat exchange box 3, the water storage layer 9, the filter cylinder 1102 and the connecting pipeline are all made of heat insulation materials.

[0035] The heat insulation material can reduce heat loss of waste hot water and waste hot gas in the conveying process, further ensure that waste heat can be transmitted to normal temperature water as much as possible, improve waste heat recovery rate, and further realize energy saving and cost reduction.

[0036] Working principle of the present application: When the bathing room 2 is used, the water supply pump 5 and the heat exchange pump 10 are started, the waste water generated by bathing flows into the water storage layer 9 through the sewage pipe, the heat exchange pump 10 pumps the hot waste water into the heat exchange box 3, and the water supply pump 5 pumps the normal temperature water into the heating element 4, the normal temperature water flows into the heating element 4 for heating after flowing through the heat exchange inner pipe 6, and finally enters the bathing room for bathing, the normal temperature water exchanges heat with the waste hot water through the heat exchange inner pipe 6 when flowing through the heat exchange box 3, the waste hot water can preheat the normal temperature bathing water, the heat energy in the waste hot water is recycled, resources are saved, and cost is reduced.

[0037] When the waste hot water enters the heat exchange box 3, it flows to the heat exchange inner pipe 6 through the small holes on the shunt pipe 13, which can ensure uniform distribution of the waste hot water in the heat exchange box 3, effectively improve the heat exchange efficiency, and further improve the waste heat utilization rate.

[0038] When the bathing room 2 is used, the exhaust fan 19 is opened to exhaust the waste hot gas generated through the gas pipe 18 into the lower part of the partition plate 22 in the heat exchange box 3, the temperature of the waste hot gas is higher than that of the normal temperature water, and in the heat exchange box 3, the normal temperature water can also absorb the heat energy in the waste hot gas through the heat exchange inner pipe 6, further improving the overall waste heat recovery of the bathing room, realizing the combined recovery of the heat energy in the waste hot water and the waste hot gas, further saving energy and reducing cost; when the waste hot gas enters the heat exchange box 3, under the obstruction of the slow flow plate 15, the waste hot gas cannot be directly discharged from the air outlet valve 20, but can slowly blow the air outlet valve 20 through the slow flow hole 16, which can effectively prolong the residence time of the waste hot gas in the heat exchange box 3, and improve the heat exchange efficiency of the waste hot gas and the normal temperature water.

[0039] The bathing waste water carries dirt and sundries, when the dirt is conveyed into the heat exchange box 3, it will adhere to the outer wall of the heat exchange inner pipe 6, thereby reducing the heat exchange efficiency between the waste hot water and the normal temperature bathing water and damaging the heat exchange inner pipe 6, before the waste hot water enters the heat exchange box 3, it flows through the filter plate 1109, which can reduce the dirt in the waste hot water, ensure the heat exchange efficiency and prolong the service life of the heat exchange inner pipe 6.

[0040] When the waste hot water flows through the annular water pipe 1104, it will impact the impeller blades 1106, which will rotate around the rotating rod 1105. The impeller blades 1106 will drive the scraper 1111 to remove the dirt on the surface of the filter plate 1109 through the rotating rod 1105 and the transmission rod 1110. The dirt will fall into the dirt storage tank 1112 at the edge of the filter plate 1109, avoiding the dirt from blocking the filter plate 1109 and affecting the filtering efficiency of the waste hot water. Every certain period of time, the worker needs to disassemble the bottom cover 1103 to clean the waste in the dirt storage tank 1112, ensuring the continuous use of the filter assembly 11.

[0041] The sensing beads 2109 in the heat exchange box 3 sense the temperature of the waste hot water in the heat exchange box 3, and the sensing beads 2109 outside the heat exchange box 3 sense the outside temperature to represent the temperature of the normal temperature bath water entering the heat exchange inner pipe 6. In the initial state, the sliding rod 2108 is located in the slidable range close to the outside of the heat exchange box 3, and the blocking block 2105 blocks the through hole 2106. At this time, the waste hot water in the heat exchange box 3 is being exchanged with the normal temperature bath water in the heat exchange inner pipe 6. After a certain period of time of heat exchange, the heat energy contained in the waste hot water decreases, and the temperature drops. The thermal sensitive gas 2110 close to the inside of the heat exchange box 3 shrinks in volume, and the sliding rod 2108 moves towards the inside of the heat exchange box 3. When the sliding rod 2108 moves, it drives the adjusting rod 2111 to move synchronously. When the adjusting rod 2111 touches the press switch 2112, the press switch 2112 will control the electric telescopic rod 2104 to retract, and the electric telescopic rod 2104 drives the blocking block 2105 to cancel the blocking of the through hole 2106, so that the waste water with reduced temperature is discharged from the heat exchange box 3. The more the temperature of the waste hot water decreases, the more complete the heat exchange is, and the greater the adjusting rod 2111 moves. The three press switches 2112 control the electric telescopic rod 2104 to retract to different degrees, and the farther away from the press switch 2112 controls the electric telescopic rod 2104 to retract more, so as to realize the control of the discharge speed of the waste water by reducing the temperature of the waste hot water. The heat carried by the discharged waste water can be reduced, thereby improving the heat exchange efficiency and further saving energy and reducing cost.

[0042] The heat insulation material can reduce the heat loss of the waste hot water and waste hot gas during transportation, further ensure that the waste heat can be transmitted to the normal temperature water as much as possible, improve the waste heat recovery rate, and further realize energy saving and cost reduction.
