Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, and in particular to a triple-effect evaporator. Background Technology

[0002] The triple-effect evaporator is an extraction and concentration device that adopts the working principle of shell-and-tube circulating external heating. It has a short physical heating time, fast evaporation speed, and high concentration ratio, effectively maintaining the original effect of the material. It has significant energy-saving effect and is widely suitable for the evaporation and concentration process of liquid materials in pharmaceutical, chemical, food, and light industries. After the mother liquor is concentrated, it is discharged.

[0003] In the process of concentrating mother liquor in a triple-effect evaporator, the mother liquor passes directly through the heat exchanger under the action of gravity, thereby achieving heat exchange and concentration of the mother liquor. This results in the mother liquor passing through the heat exchanger at a very slow speed, which can easily cause blockage in the heat exchanger tubes, thus affecting the efficiency of mother liquor evaporation and concentration. Utility Model Content

The insulated water tank is used to store water, the submersible pump is used to pump water out of the insulated water tank, and the metal pipes are used to transport water.

[0008] Furthermore, an installation groove is provided on the inner surface of the main body. One end of the metal tube first penetrates the interior of the main body and finally extends into the interior of the insulated water tank. The metal tube is installed inside the installation groove within the main body. The installation groove is provided to facilitate the positioning and installation of the metal tube.

[0009] Furthermore, the metal tubes are arranged in a spiral pattern inside the main body, and the heat exchanger is located inside the metal tubes.

[0011] Furthermore, the bottom of the main body is fixedly connected with support legs, which are made of triangular steel. The support legs are provided for convenient positioning and support of the main body, and the triangular steel material is chosen to improve the stability of the support.

[0012] Furthermore, the evaporator body, mother liquor tank, pump body, separator, and hydrolysis tank are connected together by pipelines.

[0013] The beneficial effects of this utility model are as follows: by setting up a heat exchange mechanism and a pressurization mechanism, high-pressure steam can be used to drive the mother liquor to flow, thereby increasing the flow rate of the mother liquor in the heat exchanger.

[0026] Reference Figures 1 to 7 A triple-effect evaporator includes an evaporator body 10, a mother liquor tank 12, a pump body 11, a separator 13, and a hydrolysis tank 14. The evaporator body 10, mother liquor tank 12, pump body 11, separator 13, and hydrolysis tank 14 are connected together by pipes. The evaporator body 10, mother liquor tank 12, pump body 11, and separator 13 form an evaporation assembly. The triple-effect evaporator includes three evaporation assemblies and a hydrolysis tank 14.

[0027] The evaporator body 10 includes a main body 1, a heat exchange mechanism, and a preheating mechanism. The heat exchange structure includes a heat exchanger 6, which consists of two fixed plates and several heat exchange tubes. The heat exchange tubes are made of copper alloy. The fixed plates are fixed to both ends of the heat exchange tubes and are welded together. Vent holes are provided on the side surface near the bottom fixed plate, and the top fixed plate is in close contact with the inner surface of the main body 1. The heat exchange mechanism and the preheating mechanism are both installed inside the main body 1. The preheating mechanism includes an insulated water tank 2, a submersible pump 15, and a metal pipe 7. The insulated water tank 2 is annular in shape. 2 is fixedly connected to the outer surface of the main body 1. The submersible pump 15 is fixedly connected to the inner bottom of the insulated water tank 2. The metal pipe 7 is fixedly connected to the output end of the submersible pump 15. The metal pipe 7 is made of copper alloy. A pressurizing mechanism is installed inside the main body 1. The pressurizing mechanism includes an air pump 16, a delivery pipe 17 and a connecting pipe 18. The delivery pipe 17 is installed at the input end of the air pump 16. The connecting pipe 18 is installed at the output end of the air pump 16. The delivery pipe 17, away from the input end of the air pump 16, is connected to the inside of the air outlet pipe 8. The connecting pipe 18, away from the output end of the air pump 16, extends into the inside of the main body 1.

[0028] The inner surface of the main body 1 is provided with a mounting groove 9, which is located in the middle of the interior of the main body 1. One end of the metal tube 7 first penetrates the interior of the main body 1 and finally extends into the interior of the insulated water tank 2. The metal tube 7 is spirally arranged inside the main body 1. The heat exchanger 6 is located inside the metal tube 7. The metal tube 7 is installed inside the mounting groove 9. The bottom of the main body 1 is fixedly connected with a support leg 3, which is made of triangular steel.

[0029] The top of the main body 1 is fixedly connected to the feed pipe 4, the bottom of the main body 1 is fixedly connected to the discharge pipe 5, and the side surface of the main body 1 is fixedly connected to the air outlet pipe 8. The feed pipe 4, the discharge pipe 5 and the air outlet pipe 8 are connected to the interior of the main body 1.

[0030] Working principle: During use, the mother liquor in the mother liquor tank 12 is drawn into the evaporator body 10 by the pump body 11 for concentration. Then the concentrated liquid is discharged into the separator 13, and the gas in the evaporator body 10 is discharged. Subsequently, the vacuum pump 16 is used to re-extract some of the steam in the exhaust pipe 8 to the top of the heat exchanger 6, thereby increasing the air pressure above the heat exchanger 6 and pushing the mother liquor in the heat exchanger 6 to flow downward faster. This can effectively prevent the mother liquor from clogging in the heat exchanger 6, while the other part of the steam directly enters the next evaporation component.

[0031] During the concentration of the mother liquor, a submersible pump 15 draws water from the insulated water tank 2 into the metal pipe 7, and then circulates it back into the insulated water tank 2. Heat from the evaporator body 10 is transferred to the water through the metal pipe 7. After the water in the insulated water tank 2 is heated, the submersible pump 15 draws water from the insulated water tank 2 and transports it through the metal pipe. During the water transport process, the metal pipe 7 dissipates heat to the surroundings, which in turn raises the temperature in the evaporator body 10.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
