Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and in particular to a lithium bromide chiller unit that can utilize waste heat steam from chloroacetic acid. Background Technology

[0002] A steam-type lithium bromide absorption chiller is a device that uses water as a refrigerant and lithium bromide solution as an absorbent, and achieves refrigeration by means of steam heat.

[0003] During equipment operation, low-pressure steam needs to be continuously input as the heat source for the chiller unit. This steam usually comes from a boiler or other steam generating device. Since the process of generating steam consumes other energy and the operation of the unit consumes a lot of steam, this results in a lot of energy consumption, which is not conducive to energy conservation. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide a lithium bromide chiller unit that can utilize waste heat steam from chloroacetic acid, so as to solve the problems existing in the prior art.

[0005] The present invention adopts the following technical solution:

Detailed Implementation

[0017] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, this embodiment discloses a lithium bromide chiller unit that can utilize waste heat steam from chloroacetic acid, including a chiller unit body 1, a chloroacetic acid waste heat steam pipeline 2, and a low-pressure steam pipeline 3. The low-pressure steam pipeline 3 is connected to a corresponding position of the chiller unit body 1. A gas-liquid separator 5 is connected to the chloroacetic acid waste heat steam pipeline 2 through a pipeline assembly 4. The gas outlet of the gas-liquid separator 5 is connected to the low-pressure steam pipeline 3 through a pipeline assembly 6.

[0019] In this embodiment, the waste heat steam in the chloroacetic acid waste heat steam pipeline 2 can be transported to the gas-liquid separator 5 through the pipeline assembly 1 4. The gas-liquid separator 5 separates the waste heat steam into gas and liquid to remove the moisture contained in the waste heat steam. The separated steam enters the low-pressure steam pipeline 3 through the pipeline assembly 2 6, and then enters the chiller unit body 1 through the low-pressure steam pipeline 3 as a heat source.

[0020] Specifically, pipeline assembly 4 includes pipeline 41 which is fixedly connected to the chloroacetic acid waste heat steam pipeline 2. The end of pipeline 41 is fixedly connected to the inlet of the gas-liquid separator 5, and valve 1 is fixedly installed on pipeline 41. Pipeline assembly 6 includes pipeline 61 which is fixedly connected to the outlet of the gas-liquid separator 5. The end of pipeline 61 is fixedly connected to the low-pressure steam pipeline 3, and valve 2 is fixedly installed on pipeline 61.

[0021] By adopting this scheme and through the above-mentioned structural design, the waste heat steam in the chloroacetic acid waste heat steam pipeline 2 can be recovered and utilized, which effectively reduces the consumption of the original low-pressure steam, thereby reducing energy consumption and contributing to energy conservation.

[0022] Further optimization of the scheme: the main body 1 of the chiller unit includes the main unit 11 and the circulating water system 12 connected to the main unit 11. The low-pressure steam pipeline 3 is connected to the main unit 11. The liquid outlet of the gas-liquid separator 5 is connected to the circulating water system 12 through the pipeline assembly 3 13.

[0023] In this embodiment, the circulating water system 12 includes a circulating water tank 121. The outlet and return outlet of the circulating water tank 121 are connected to corresponding positions of the main unit 11 through the circulating water inlet pipe 122 and the circulating water return pipe 123, respectively. The circulating water tank 121 mainly serves to store cooling water and circulate heat dissipation. During circulation, the cooling water undergoes heat exchange through the tank, and after its temperature is reduced, it flows back to the unit for continued use, forming the circulating water system 12. During circulation, the circulating water in the circulating water tank 121 enters the main unit 11 through the outlet and the circulating water inlet pipe 122, undergoes heat exchange, and then flows back to the circulating water tank 121 through the circulating water return pipe 123 and the return outlet. The liquid outlet of the gas-liquid separator 5 is connected to the circulating water tank 121 through the pipeline assembly 3 13.

[0024] The liquid separated from the waste heat steam by the gas-liquid separator 5 enters the circulating water tank 121 through pipeline assembly 3 13 as a supplement to the circulating water. This structural arrangement ensures that the moisture contained in the waste heat steam is fully utilized.

[0025] Specifically, the pipeline assembly 313 includes a pipeline 3131 that is fixedly connected to the circulating water tank 121, and the end of the pipeline 3131 is fixedly connected to the liquid outlet of the gas-liquid separator 5 through a condensate drain.

[0026] Further optimization of the scheme also includes a main unit condensate recovery system 7, which includes a condensate tank 71. The inlet of the condensate tank 71 is connected to the corresponding position of the main unit 11 through a recovery pipe 72, and the outlet of the condensate tank 71 is connected to the circulating water system 12 through a recovery pipe 73. A condensate recovery pump 74 is fixedly installed on the recovery pipe 73.

[0027] In this embodiment, the second recovery pipe 73 is connected to the circulating water tank 121. The condensate generated during the operation of the main unit 11 enters the condensate tank 71 through the first recovery pipe 72, and then the condensate in the condensate tank 71 is transported to the circulating water tank 121 through the condensate recovery pump 74 and the second recovery pipe 73 as a supplement to the circulating water. Through the above structure, the condensate generated by the main unit 11 is fully utilized.

[0028] In a further optimized design, a remote pressure gauge 21 and an automatic valve 22 are installed sequentially along the flow direction of the medium on the chloroacetic acid waste heat steam pipeline 2. The remote pressure gauge 21 and the automatic valve 22 are respectively located on both sides of the connection between the pipeline assembly 4 and the chloroacetic acid waste heat steam pipeline 2.

[0029] In this embodiment, the pressure inside the chloroacetic acid waste heat steam pipeline 2 can be monitored by the remote pressure gauge 21, and the automatic valve 22 is used to open or close the chloroacetic acid waste heat steam pipeline 2.

[0030] Further optimization of the scheme also includes a control device, with the remote pressure gauge 21 and the automatic valve 22 electrically connected to the control device.

[0031] In this embodiment, the remote pressure gauge 21 transmits the monitored pressure data to the controller in the form of a signal. After receiving the signal, the controller can control the opening or closing of the automatic valve 22. In use, a preset pressure can be preset. When the preset pressure is reached, the controller controls the automatic valve 22 to open; when the pressure is lower than the preset pressure, the controller controls the automatic valve 22 to close, so as to achieve the purpose of automatic adjustment.

[0032] The scheme is further optimized by fixing a desuperheating and pressure reducing valve 31 and an automatic valve 32 on the low-pressure steam pipeline 3. The desuperheating and pressure reducing valve 31 and the automatic valve 32 are both located on the rear side of the connection between the pipeline assembly 6 and the low-pressure steam pipeline 3.

[0033] In this embodiment, when the temperature of the waste heat steam from chloroacetic acid cannot meet the requirements of the unit, opening automatic valve 2 32 can supplement low-pressure steam to meet the normal operating needs of the unit.

[0034] It should be noted that in this embodiment, the chiller unit body 1 also includes a chilled water tank 8, which is connected to the corresponding position of the main unit 11. The chilled water tank 8 is mainly used to store and circulate chilled water to ensure that the evaporator in the main unit 11 always has enough low-temperature chilled water to participate in heat exchange. The chilled water tank 8, the circulating water system 12 and the main unit 11 are all existing technologies, and their working principles, connections and usage methods are known, so they will not be described in detail here.

[0035] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
