Description
Technical Field
[0001] This invention relates to the field of hydrophobic energy-saving technology, and more specifically, to a steam hydrophobic energy-saving device. Background Technology
[0002] A steam heat exchanger is a device that uses steam as a heat source to heat water or air. It can effectively remove a large amount of calorific value from steam to heat water or air. The heated water or air can then be centrally transported to various drying equipment. In modern industry, steam has become a widely used and ideal heat transfer medium.
[0003] Currently, most stretching machines and leather dryers use steam heat exchange for heating. A steam trap is installed at the steam discharge end of the stretching machine or leather dryer to periodically drain condensate. When the steam trap closes, a burst of steam is released from the steam heat exchanger. Over time, this results in a large amount of steam being released, leading to energy waste. Furthermore, each stretching machine or leather dryer has several to dozens of steam traps, depending on the number of units. The amount of steam discharged daily is considerable. Especially with increasingly stringent environmental regulations and the widespread use of clean energy, the leather industry faces significant pressure. The operating costs of using clean energy are much higher than those of using coal. Therefore, controlling steam loss during condensation is a pressing issue that needs to be addressed.

It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0057] See Figure 1-2 As shown, this embodiment provides a vapor trap energy-saving device, including:
[0058] A steam heat exchanger 110 is installed inside the machine body; a heat dissipation component is connected to the drain pipe of the steam heat exchanger 110 to utilize the waste heat of the steam condensate discharged from the steam heat exchanger 110; a drain control valve is fixedly installed on the drain pipe to control the flow direction and flow rate of the steam condensate; a detection device is installed inside the drain pipe to detect the temperature of the steam condensate; a control device 150 is electrically connected to the drain control valve and the detection device, and the control device 150 is fixedly installed on the drain pipe to control the opening state of the drain control valve; a collection device 160 is connected to the drain end of the heat dissipation component to collect the water discharged from the heat dissipation component.
[0059] It is understood that a steam trap energy-saving device typically includes a heating layer 100 and a drying layer 200. The heating layer 100 provides heat, and the drying layer 200 uses the heat to dry the object. In this application, the steam heat exchanger 110, heat dissipation components, drain control valve, detection device, and control device 150 are located on the heating layer 100, and the collection device 160 can be located outside the steam trap energy-saving device to facilitate the collection and reuse of the discharged water.
[0060] In some embodiments of this application, the drainage pipe includes: a main drainage pipe 171, a first pipe 172, a second pipe 173, and a third pipe 174; the heat dissipation component includes: a first radiator 121, a second radiator 122, and a third radiator 123, wherein the first radiator 121 is fixed to the first pipe 172, the second radiator 122 is fixed to the second pipe 173, and the third radiator 123 is fixed to the third pipe 174; the detection device includes: a main line detector 141, a first detector 142, a second detector, and a third detector, wherein the main line detector 141 is fixed to the main drainage pipe 171, the first detector 142 is fixed to the third pipe 174, and the second radiator 173 is fixed to the third pipe 174; The first detector is fixed to the first pipe 172; the second detector is fixed to the second pipe 173; the third detector is fixed to the third pipe 174; the drainage control valve includes: a first inlet control valve 131, a first outlet control valve 132, a second inlet control valve 133, a second outlet control valve 134, a third inlet control valve 135, and a third outlet control valve 136, wherein the first inlet control valve 131 and the first outlet control valve 132 are fixed to the first pipe 172, the second inlet control valve 133 and the second outlet control valve 134 are fixed to the second pipe 173, and the third inlet control valve 135 and the third outlet control valve 136 are fixed to the third pipe 174.
[0061] Understandably, the condensate drain pipe provides three branches for the steam condensate discharged from the steam heat exchanger 110. Each branch is equipped with a radiator, a detector, and a control valve to regulate the flow rate in the branch, which is beneficial for making full use of the waste heat of the steam condensate.
[0062] In some embodiments of this application, the drainage pipe further includes: a first circulation pipe 175 for connecting the first pipe 172 and the second pipe 173; a second circulation pipe 176 for connecting the first pipe 172 and the third pipe 174; and a third circulation pipe 177 for connecting the second pipe 173 and the third pipe 174.
[0063] It is understandable that the first circulation pipe 175, the second circulation pipe 176 and the third circulation pipe 177 are designed to provide more paths for steam condensate. When the steam condensate temperature is high and a single radiator cannot dissipate heat sufficiently, the purpose of sufficient heat dissipation can be achieved by extending the heat dissipation path.
[0064] In some embodiments of this application, the main pipeline detector 141 is used to detect the steam condensate temperature T11 in the main drainage pipe 171, and presets a first preset temperature T1, a second preset temperature T2, a third preset temperature T3, and a fourth preset temperature T4, wherein T1 < T2 < T3 < T4; the control device 150 is also used to control the opening state of the first water inlet control valve 131, the second water inlet control valve 133, and the third water inlet control valve 135 according to the relationship between T11 and each preset temperature; when T1 < T11 ≤ T2, the control device 150 opens the first water inlet control valve 131. The control device 150 controls the opening degree of the first water inlet control valve 131 to K0. When T2 < T11 ≤ T3, the control device 150 opens the first water inlet control valve 131 and the second water inlet control valve 133, and controls the opening degree of the first water inlet control valve 131 and the second water inlet control valve 133 to K0. When T3 < T11 ≤ T4, the control device 150 opens the first water inlet control valve 131, the second water inlet control valve 133 and the third water inlet control valve 135, and controls the opening degree of the first water inlet control valve 131, the second water inlet control valve 133 and the third water inlet control valve 135 to K0.
[0065] It is understandable that installing a main line detector 141 in the main condensate drain pipe 171 to initially detect the steam condensate temperature, and opening different pipes according to the temperature, is beneficial for quickly utilizing the waste heat of the steam condensate, reducing the waste heat dissipation time, and improving the operating efficiency of the device. The opening degree K0 can be fully open, or a specific opening degree can be set according to actual needs.
[0066] In some embodiments of this application, when steam condensate flows into the first radiator 121 through the first inlet control valve 131, after a preset heat dissipation time, the steam condensate flows out of the first radiator 121 and passes through the first detector 142; the first detector 142 detects the steam condensate temperature T12 at this time and calculates the difference T11-T12 with T11. The first detection device is also used to preset a first preset difference A1, a second preset difference A2, a third preset difference A3 and a fourth preset difference A4, and A1 < A2 < A3 < A4; the control device 150 is also used to adjust the opening degree of the first inlet control valve 131 and control the opening state of the first outlet control valve 132 according to the relationship between T11-T12 and each preset difference.
[0067] In some embodiments of this application, the control device 150 is further configured to adjust the opening degree of the first water inlet control valve 131 and control the opening state of the first water outlet control valve 132 according to the relationship between T11-T12 and each preset difference, including: the first detector 142 is further configured to set a first adjustment coefficient B1, a second adjustment coefficient B2, a third adjustment coefficient B3 and a fourth adjustment coefficient B4, where B1 < B2 < B3 < B4; when T11-T12 < A1, the control device 150 selects the fourth adjustment coefficient B4 to adjust the opening degree K0 of the first water inlet control valve 131, and the adjusted opening degree of the first water inlet control valve 131 is K0*B4; the control device 150 is further configured to control the first water outlet control valve 132 to connect to the drainage pipe; when A1 ≤ T11-T12 < A2, the control device 150 selects the third adjustment coefficient B3 to adjust the opening degree K0 of the first water inlet control valve 131. After adjustment, the opening degree of the first water inlet control valve 131 is K0*B3; the control device 150 is also used to control the first water outlet control valve 132 to connect to the first circulation pipe 175; when A2≤T11-T12<A3, the control device 150 selects the second adjustment coefficient B2 to adjust the opening degree K0 of the first water inlet control valve 131, and after adjustment, the opening degree of the first water inlet control valve 131 is K0*B2; the control device 150 is also used to control the first water outlet control valve 132 to connect to the second circulation pipe 176; when A3≤T11-T12≤A4, the control device 150 selects the first adjustment coefficient B1 to adjust the opening degree K0 of the first water inlet control valve 131, and after adjustment, the opening degree of the first water inlet control valve 131 is K0*B1; the control device 150 is also used to control the first water outlet control valve 132 to connect to the first circulation pipe 175 and the second circulation pipe 176.
[0068] Understandably, when steam condensate passes through the first pipe 172, the first detector 142 detects and compares the temperature after passing through the first radiator 121. Adjusting the opening degree of the first water inlet control valve 131 based on the difference can regulate the flow rate of steam condensate in the radiator, achieving sufficient heat dissipation. Furthermore, when the temperature in the first pipe 172 is still high after being dissipated by the first radiator 121, the waste heat of the steam condensate can be reused again through the first circulation pipe 175 and the second circulation pipe 176, effectively utilizing the heat of the steam condensate.
[0069] In some embodiments of this application, the second detector includes a second water inlet detector 143 and a second water outlet detector 144. When steam condensate flows into the second radiator 122 through the second water inlet detector 143, after a preset heat dissipation time S0, the steam condensate flows out of the second radiator 122 and passes through the second water outlet detector 144. The second water inlet detector 143 detects the temperature T21 before entering the second radiator 122, and the second water outlet detector 144 detects the temperature T22 before flowing out of the second radiator 122. The second water outlet detector 144 is also used to calculate the difference between T21 and T22, T21-T22. The second water outlet detector 144 is also used to preset a first temperature difference C1, a second temperature difference C2, and a third temperature difference C3, where C1 < C2 < C3. The control device 150 is also used to adjust the heat dissipation time S0 according to the relationship between T21-T22 and each temperature difference and to control the opening state of the second water outlet control valve 134.
[0070] In some embodiments of this application, the control device 150 is further configured to adjust the heat dissipation time S0 according to the relationship between T21-T22 and each temperature difference and control the opening state of the second water outlet control valve 134, including: the second water outlet detector 144 is further configured to set a first correction coefficient D1, a second correction coefficient D2, and a third correction coefficient D3, where D1 < D2 < D3; when T21-T22 < C1, the control device 150 selects the third correction coefficient D3 to adjust the heat dissipation time S0, and the adjusted heat dissipation time is S0*D3; the control device 150 is further configured to control the second water outlet Control valve 134 is connected to the drainage pipe; when C1≤T21-T22<C2, the control device 150 selects a second correction coefficient D2 to adjust the heat dissipation time S0, and the adjusted heat dissipation time is S0*D2; the control device 150 is also used to control the second outlet control valve 134 to connect to the drainage pipe; when C2≤T21-T22≤C3, the control device 150 selects a first correction coefficient D1 to adjust the heat dissipation time S0, and the adjusted heat dissipation time is S0*D1; the control device 150 is also used to control the second outlet control valve 134 to connect to the third circulation pipe 177.
[0071] Understandably, when the steam condensate passes through the second pipe 173, the second inlet water detector 143 and the second outlet water detector 144 in the second detector detect the temperature of the steam condensate before and after entering the second radiator 122, respectively, and adjust the duration of heat dissipation of the steam condensate in the second radiator 122 according to the temperature difference, and open the third circulation pipe 177 according to the temperature difference to make full use of the waste heat of the steam condensate.
[0072] In some embodiments of this application, the third detector includes a third water inlet detector 145 and a third water outlet detector 146. When steam condensate flows into the third radiator 123 through the third water inlet detector 145, after a preset heat dissipation time S0, the steam condensate flows out of the third radiator 123 and passes through the third water outlet detector 146. The third water inlet detector 145 detects the temperature T31 before entering the third radiator 123, and the third water outlet detector 146 detects the temperature T32 before flowing out of the third radiator 123. The third water outlet detector 146 is also used to calculate the difference T31-T32 between T31 and T31. The third detection device is also used to preset a first preset threshold E1, a second preset threshold E2, and a third preset threshold E3, where E1 < E2 < E3. The control device 150 is also used to adjust the heat dissipation time S0 according to the relationship between T31-T32 and each preset threshold and control the opening state of the third water outlet control valve 136.
[0073] In some embodiments of this application, the control device 150 is further configured to adjust the heat dissipation time S0 according to the relationship between T31-T32 and each preset threshold and control the opening state of the third water outlet control valve 136, including: the third water inlet detector 145 is further configured to set a first correction coefficient F1, a second correction coefficient F2 and a third correction coefficient F3, and F1 < F2 < F3; when T31-T32 < E1, the control device 150 selects the third correction coefficient F3 to adjust the heat dissipation time S0, and the adjusted heat dissipation time S0 is S0*F3; the control device 150 is further configured to control the opening state of the third water outlet control valve 136. The three-outlet control valve 136 connects to the drainage pipe; when E1≤T31-T32<E2, the control device 150 selects the second correction coefficient F2 to adjust the heat dissipation time S0, and the adjusted heat dissipation time S0 is S0*F2; the control device 150 is also used to control the third-outlet control valve 136 to connect to the drainage pipe; when E2≤T31-T32≤E3, the control device 150 selects the first correction coefficient F1 to adjust the heat dissipation time S0, and the adjusted heat dissipation time S0 is S0*F1; the control device 150 is also used to control the third-outlet control valve 136 to connect to the drainage pipe.
[0074] It is understandable that when the steam condensate passes through the third pipe 174, the third inlet water detector 145 and the third outlet water detector 146 in the third detector detect the temperature of the steam condensate before and after entering the third radiator 123, and adjust the duration of heat dissipation of the steam condensate in the third radiator 123 according to the temperature difference to make full use of the waste heat of the steam condensate.
[0075] This application incorporates heat dissipation components to utilize the waste heat of the steam condensate in the steam heat exchanger 110, reducing resource waste and helping to reduce production costs. It also includes a drain control valve, a detection device, and a control device 150 to dynamically adjust the heat dissipation of the steam condensate, fully utilizing the waste heat. Furthermore, the control device 150 can regulate the flow direction and velocity of the steam condensate, preventing situations where the condensate flows too fast and fails to dissipate heat sufficiently, or flows too slowly and reduces the effectiveness of the steam heat exchanger 110. Finally, a collection device 160 collects the fully cooled steam condensate, preventing water waste and further reducing production costs.
