Description

Technical Field

[0001] The utility model relates to the field of heat pump equipment, in particular to a heat pump type water heating and drying system. Background Art

[0002] In industrial production, materials often need to be dried. Drying equipment requires a heat source to provide the heat required for drying. Common sources of heat sources include coal, natural gas and other difficult-to-renew energy sources. Coal has the advantage of low cost, but coal is a non-renewable energy source and will pollute the atmosphere during combustion. Natural gas is a clean energy source, but its cost is relatively high, which limits its application in industry. In view of the problems of high cost and environmental pollution, the utility model provides a heat pump type water heating drying system, which reduces the cost of drying and does not pollute the environment. Utility Model Content

[0003] In view of this, the utility model provides a heat pump type water heating drying system, which can add a certain refrigerant in the condensing pipe. The refrigerant is lower than the ambient temperature, and the heat in the air will be transferred to the refrigerant. The condensing pipe is connected to the evaporator to better promote heat transfer. When the refrigerant absorbs heat and causes the refrigerant temperature to rise, the refrigerant will be converted into low-pressure steam. After the refrigerant is converted into low-pressure steam, it is transported to the compressor through the output pipe. The low-pressure steam is compressed into high-temperature and high-pressure gas by the compressor. The high-temperature and high-pressure gas is transported to the circulation pipe, so that the cold water in the heat exchange box absorbs and converts the heat in the high-temperature gas. When the high-temperature gas flows through the circulation pipe, the high-temperature gas is cooled, and the high-pressure gas after cooling is cooled and depressurized through the expansion valve on the return pipe, so that the refrigerant after cooling and depressurization flows back into the condensing pipe for circulation. The cold water in the heat exchange box is converted into hot water by temperature conversion with the high-temperature and high-pressure gas in the circulation pipe, and is transported to the shunt pipe through the delivery pipe. The shunt pipe disperses the hot water to the heat dissipation pipe in the drying box, thereby increasing the temperature in the drying box and drying the material in the drying box.

[0004] In order to solve the above technical problems, the utility model provides a heat pump type water heating and drying system, including a heat exchange box, which is used to store cold water and complete heat exchange in the heat exchange box. A condensing component is provided on one side of the heat exchange box, which is used to absorb heat in the air and convert the heat into high-temperature and high-pressure thermal energy. A drying component is provided on the other side of the heat exchange box, which is used to use a heat source to dry the material.

[0005] The condensing assembly includes an evaporator, which is used to make the refrigerant in the condensing pipe transfer heat just right. The evaporator is arranged on one side of the heat exchange box. The evaporator is provided with a condensing pipe inside, and the condensing pipe is used to store the refrigerant.

[0006] A circulation pipe is provided in the heat exchange box, and the circulation pipe is used to allow high-temperature and high-pressure gas to circulate in the heat exchange box so that cold water can convert the high temperature in the circulation pipe. A first feed port is provided at one end of the condensation pipe, and a first discharge port is provided at the other end of the condensation pipe. A second feed port is provided at one end of the circulation pipe, and a second discharge port is provided at the other end of the circulation pipe.

[0007] An output pipeline is connected between the first discharge port and the second feed port, and a compressor is connected to the output pipeline. The compressor is used to heat and pressurize the low-temperature and low-pressure gas, and the output pipeline is used to transport the high-temperature and high-pressure gas.

[0008] A reflux pipe is connected between the first feed port and the second discharge port. The reflux pipe is used to transport the refrigerant after heat exchange back to the condensation pipe. An expansion valve is provided on the reflux pipe. The expansion valve is used to reduce the pressure and temperature of the low-temperature and high-pressure gas. A water inlet pipe is provided on the side of the heat exchange box away from the reflux pipe. The water inlet pipe is used to add cold water to the heat exchange box. A water outlet pipe is provided above the water inlet pipe. The water outlet pipe facilitates the outflow of heated hot water.

[0009] A drying box is provided on one side of the heat exchange box. The drying box is used to store and dry materials. A conveying pipe is connected to the water outlet pipe. The conveying pipe is used to convey hot water. A diversion pipe is connected to the conveying pipe. The diversion pipe is used to divert the hot water so that the hot water can be more evenly distributed in the drying box.

[0010] The shunt pipe is arranged in the drying box, and a plurality of heat dissipation pipes are connected to the shunt pipe. The heat dissipation pipes facilitate hot water to dissipate heat to dry the materials in the drying box.

[0011] The beneficial effects of the above technical solution of the utility model are as follows:

[0012] 1. Add a certain amount of refrigerant into the condensing pipe. The refrigerant is lower than the ambient temperature. The heat in the air will be transferred to the refrigerant. Connecting the condensing pipe to the evaporator is to better promote heat transfer. When the refrigerant absorbs heat and causes the refrigerant temperature to rise, the refrigerant will be converted into low-pressure steam.

[0013] 2. When the refrigerant is converted into low-pressure steam, it is transported to the compressor through the output pipeline. The low-pressure steam is compressed into high-temperature and high-pressure gas by the compressor. The high-temperature and high-pressure gas is transported to the circulation pipeline, so that the cold water in the heat exchange box absorbs and converts the heat in the high-temperature gas. When the high-temperature gas flows through the circulation pipeline, the high-temperature gas is cooled, and the cooled high-pressure gas is cooled and reduced in pressure through the expansion valve on the return pipeline, so that the cooled and reduced-pressure refrigerant flows back into the condensation pipeline for circulation.

[0014] 3. The cold water in the heat exchange box is converted into hot water by the temperature conversion of the high-temperature and high-pressure gas in the circulation pipe, and is transported to the diversion pipe through the delivery pipe. The diversion pipe disperses the hot water to the heat dissipation pipe in the drying box, thereby increasing the temperature in the drying box and drying the materials in the drying box.
