Description

Technical Field

[0001] This utility model relates to a waste heat recovery system, specifically a waste heat recovery and preheating system for dishwasher wastewater, belonging to the field of waste heat recovery technology. Background Technology

[0002] Dishwashers are automatic dishwashing devices, available in both residential and commercial models, that clean dishes using water flow and high temperatures. Wastewater refers to contaminated water after use; it comes from various sources and contains different pollutants. Dishwasher wastewater contains grease, food residue, etc., and must be treated to meet discharge standards. Proper wastewater treatment is environmentally friendly, and the water-saving design of dishwashers also helps reduce wastewater.

[0003] Wastewater is often at a high temperature. When traditional dishwashers discharge hot wastewater into the sewer, the heat energy is lost, resulting in energy loss. This means that the heat energy contained in the hot wastewater is not fully utilized.

[0004] Furthermore, the washing water temperature varies depending on the dishwasher's operating mode. For example, the gentle wash mode uses a lower water temperature to protect delicate tableware, while the standard wash mode uses a higher water temperature. Therefore, a waste heat recovery and preheating system for dishwasher wastewater is proposed here. Utility Model Content

[0005] This invention proposes a waste heat recovery and preheating system for dishwasher wastewater, which can recover heat energy from high-temperature wastewater and preheat purified water when the wastewater temperature is high, thereby reducing energy consumption.

[0006] This utility model is achieved through the following technical solution: a wastewater waste heat recovery and preheating system for dishwashers, including a water storage tank, the water storage tank including a tank body, a wastewater inlet pipe connected to the left side of the tank body, and a wastewater outlet pipe connected to the right side of the tank body. High-temperature wastewater can be sent into the tank body through the wastewater inlet pipe, and the wastewater after heat exchange can be discharged through the wastewater outlet pipe. Furthermore, a valve can be installed on the wastewater outlet pipe to increase the heat exchange time and improve the heat exchange effect.

[0007] It also includes a waste heat recovery component, which is installed on the water storage tank. The waste heat recovery component includes a heat exchanger, which is installed inside the tank. The first purified water outlet pipe and the first purified water inlet pipe are both installed on the left side of the tank.

[0008] The input end of the heat exchanger is connected to a first purified water inlet pipe, the output end of the heat exchanger is connected to a first purified water outlet pipe, the other end of the first purified water inlet pipe is connected to a second purified water inlet pipe, and a second purified water outlet pipe is connected between the first purified water inlet pipe and the second purified water inlet pipe.

[0009] It also includes a control component, which is installed on the first purified water inlet pipe. The control component includes a valve body, in which a slide rod is slidably and sealed, and a sealing block is fixed on the slide rod. A sealing ring is fixed on the right side of the valve body. When the sealing block abuts against the sealing ring, the purified water will be discharged through the second purified water outlet pipe and will no longer be sent into the heat exchanger.

[0010] The valve body is provided with an elastic component, which is used to drive the sealing block to abut against the sealing ring. The elastic component includes a fixing plate, which is fixed to the inner wall of the valve body. The slide rod is slidably connected to the fixing plate, and a first return spring is fixed between the fixing plate and the sealing block.

[0011] The control component also includes a temperature sensor and a drive component. The temperature sensor monitors the wastewater temperature inside the tank in real time. The drive component includes a housing fixed to the valve body. An electromagnetic coil is installed inside the housing, and a guide sleeve is fixed inside the housing. A slide rod is slidably connected inside the guide sleeve. A second return spring is fixed to the left end of the slide rod, and the left end of the second return spring is fixed to the housing. When the wastewater temperature is lower than the set value, the electromagnetic coil will be activated. After the electromagnetic coil is activated, it will drive the slide rod to move inside the housing, thereby driving the sealing block to abut against the sealing ring, so that the valve body is in a closed state.

[0012] This utility model provides a waste heat recovery and preheating system for dishwasher wastewater, which has the following beneficial effects:

[0013] 1. The dishwasher wastewater waste heat recovery and preheating system can send purified water into the heat exchanger through the second and first purified water inlet pipes. After heat exchange in the heat exchanger, the water is discharged from the first purified water outlet pipe, thus recovering heat energy from the high-temperature wastewater and preheating the purified water, thereby reducing energy consumption.

[0014] 2. The wastewater waste heat recovery preheating system of this dishwasher can detect the temperature of the wastewater through a temperature sensor. When the wastewater temperature is low, the electromagnetic coil will be activated. The electromagnetic coil will drive the slide rod and the sealing block to move through the magnetic force, so that the sealing block will press against the sealing ring and the purified water will no longer enter the heat exchanger. When the wastewater temperature inside the cabinet is high, the valve body is in a pass state, and the purified water can be smoothly sent into the heat exchanger. This device can recover heat energy from high-temperature wastewater when the wastewater temperature is high. Attached Figure Description

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0024] Please see Figures 1-4 The present invention proposes the following implementation scheme:

[0025] A wastewater waste heat recovery and preheating system for dishwashers includes a water storage tank 1, which includes a tank body 101. A wastewater inlet pipe 102 is connected to the left side of the tank body 101, and a wastewater outlet pipe 103 is connected to the right side of the tank body 101. High-temperature wastewater can be sent into the tank body 101 through the wastewater inlet pipe 102, and the wastewater after heat exchange can be discharged through the wastewater outlet pipe 103. Furthermore, a valve can be installed on the wastewater outlet pipe 103 to increase the heat exchange time and improve the heat exchange effect.

[0026] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 It also includes a waste heat recovery component 2, which is installed on the water storage tank 1. The waste heat recovery component 2 includes a heat exchanger 201, which is installed inside the housing 101. The first clean water outlet pipe 203 and the first clean water inlet pipe 202 are both installed on the left side of the housing 101.

[0027] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The input end of the heat exchanger 201 is connected to the first purified water inlet pipe 202, the output end of the heat exchanger 201 is connected to the first purified water outlet pipe 203, the other end of the first purified water inlet pipe 202 is connected to the second purified water inlet pipe 205, and the second purified water outlet pipe 204 is connected between the first purified water inlet pipe 202 and the second purified water inlet pipe 205.

[0028] Please refer to this carefully. Figure 1 and Figure 4 It also includes a control component 3, which is installed on the first purified water inlet pipe 202. The control component 3 includes a valve body 301, a slide rod 302 is slidably installed inside the valve body 301, a sealing block 303 is fixed on the slide rod 302, and a sealing ring 304 is fixed on the right side inside the valve body 301. When the sealing block 303 abuts against the sealing ring 304, the purified water will be discharged through the second purified water outlet pipe 204 and will no longer be sent into the heat exchanger 201.

[0029] Please refer to this carefully. Figure 1 and Figure 4 An elastic component is provided inside the valve body 301. The elastic component is used to drive the sealing block 303 to abut against the sealing ring 304. The elastic component includes a fixing plate 305, which is fixed to the inner wall of the valve body 301. The slide rod 302 is slidably connected to the fixing plate 305. A first return spring 306 is fixed between the fixing plate 305 and the sealing block 303.

[0030] Please refer to this carefully. Figure 1 and Figure 4 The control component 3 also includes a temperature sensor 311 and a drive component. The temperature sensor 311 monitors the wastewater temperature inside the tank 101 in real time. The drive component includes a housing 307, which is fixed on the valve body 301. An electromagnetic coil 308 is installed inside the housing 307. A guide sleeve 309 is fixed inside the housing 307. A slide rod 302 is slidably connected inside the guide sleeve 309.

[0031] A second return spring 310 is fixed to the left end of the slide rod 302. The left end of the second return spring 310 is fixed to the housing 307. When the wastewater temperature is lower than the set value, the electromagnetic coil 308 will be activated. After the electromagnetic coil 308 is activated, it will drive the slide rod 302 to move inside the housing 307, and then drive the sealing block 303 to press against the sealing ring 304 through the slide rod 302, so that the valve body 301 is in a closed state.

[0032] Working principle: Wastewater is sent into the tank 101 through the wastewater inlet pipe 102 and then discharged through the wastewater outlet pipe 103. Clean water is sent into the heat exchanger 201 through the second clean water inlet pipe 205 and the first clean water inlet pipe 202. After heat exchange in the heat exchanger 201, it is discharged from the first clean water outlet pipe 203. Heat energy is recovered from the high-temperature wastewater and the clean water is preheated to reduce energy consumption.

[0033] The temperature sensor 311 can detect the temperature of the wastewater. When the wastewater temperature is low, the electromagnetic coil 308 will be activated. The electromagnetic coil 308 will drive the slide bar 302 and the sealing block 303 to move through magnetic force, so that the sealing block 303 abuts against the sealing ring 304, and the purified water will no longer enter the heat exchanger 201. When the wastewater temperature inside the box 101 is high, the electromagnetic coil 308 will no longer drive the slide bar 302. Under the elastic force of the first return spring 306 and the second return spring 310, the sealing block 303 will leave the sealing ring 304. At this time, the purified water can enter the heat exchanger 201. This device can recover heat energy from high-temperature wastewater when the wastewater temperature is high.
