Description

Technical Field

[0001] This utility model relates to the field of chemical equipment, and in particular to a pipe-jacketed cooling system. Background Technology

[0002] When filling ammonia (or other easily vaporized liquids), a long section of the pipeline is exposed to the air and the pipeline material is relatively ordinary. The factory area has a high temperature all year round. The characteristic of ammonia is that the higher the ambient temperature, the greater the saturated vapor pressure. When the temperature of ammonia is greater than 18°C, ammonia is very easy to vaporize. Therefore, when the product is being filled, if the ambient temperature is high, the ammonia is easy to vaporize and generate bubbles when the product passes through this section of pipeline exposed to the air, thus affecting the product quality.

[0003] Currently, ammonia water delivery pipelines generally use PFA pipes, with a PVC pipe wrapped around the PFA pipe and then insulation material wrapped around the PVC pipe, but the effect is not good. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a pipe jacketed cooling system with good cooling effect, ensuring that the material will not volatilize or evaporate due to high temperature during the transportation process, thus ensuring the concentration of the material and the quality of the product.

[0005] This utility model is implemented using the following solution: a pipe-jacketed cooling system, including a material storage tank, the material storage tank being connected to a material conveying pipe leading to a filling equipment, the material conveying pipe being fitted with an inner coolant pipe, the inner coolant pipe being closed at both ends and the material conveying pipe passing through the inner coolant pipe at both ends, and the inner coolant pipe being provided with an outer heat insulation layer.

[0006] Furthermore, the outer insulation layer is an outer refrigerant pipe that is wrapped around the refrigerant pipe. The inner refrigerant pipe has a refrigerant inlet at its first end, the outer refrigerant pipe has a refrigerant outlet at its first end, and the inner refrigerant pipe has a refrigerant port at its last end that connects the inner and outer refrigerant pipe cavities.

[0007] Furthermore, it also includes a refrigeration unit, the outlet of which is connected to the refrigerant inlet via a refrigerant delivery pipe, the refrigerant outlet being connected to the inlet of the refrigeration unit via a refrigerant return pipe, and a refrigerant circulation pump being installed on the refrigerant delivery pipe.

[0008] Furthermore, the outer insulation layer is made of insulation material that covers the outside of the internal refrigerant pipe.

[0009] Furthermore, the insulation material is made of PVC heat shrink film, polyethylene protective shell, or aluminum foil composite film.

[0010] Furthermore, two material conveying pipelines are connected between the material storage tank and the filling equipment. One material conveying pipeline has a refrigerant inlet at the beginning of its internal refrigerant pipeline, and the other material conveying pipeline has a refrigerant inlet at the beginning of its internal refrigerant pipeline. The ends of the internal refrigerant pipelines on the two material conveying pipelines are connected by a connecting pipe.

[0011] Furthermore, it also includes a refrigeration unit, the outlet of which is connected to the refrigerant inlet via a refrigerant delivery pipe, the refrigerant outlet being connected to the inlet of the refrigeration unit via a refrigerant return pipe, and a refrigerant circulation pump being installed on the refrigerant delivery pipe.

[0012] Furthermore, the inlet end of the material conveying pipeline is connected to the outlet at the bottom of the material storage tank, and a material conveying pump is provided near the inlet end of the material conveying pipeline.

Detailed Implementation

[0016] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0017] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0018] Example 1: As Figures 1-2 As shown, a jacketed cooling system includes a material storage tank 1 connected to a material conveying pipe 3 leading to a filling device 2. An inner refrigerant pipe 4 is fitted over the material conveying pipe, with both ends of the inner refrigerant pipe sealed and the material conveying pipe exiting from both ends. An external heat insulation layer is provided on the outside of the inner refrigerant pipe. In this jacketed cooling system, the external heat insulation layer provides a certain degree of heat insulation for the material conveying pipe during material conveying, while the refrigerant in the inner refrigerant pipe cools the material conveying pipe, ensuring that the material does not evaporate or generate bubbles due to high temperatures during conveying, thus maintaining the material concentration and product quality. This system can prevent easily vaporized liquid materials from vaporizing due to excessively high ambient temperatures when passing through exposed pipelines during the filling process, thus avoiding any impact on the quality of the filled product.

[0019] In this embodiment, the outer insulation layer is an outer refrigerant pipe 5 that is fitted over the refrigerant pipe. The inner refrigerant pipe has a refrigerant inlet 6 at its first end, the outer refrigerant pipe has a refrigerant outlet 7 at its first end, and the inner refrigerant pipe has a refrigerant port 13 at its last end that connects the inner and outer refrigerant pipe cavities. When the refrigerant passes through the inner refrigerant pipe, it cools the material conveying pipe. When the refrigerant flows back from the outer refrigerant pipe, it acts as an insulation agent, reducing the transfer of external temperature to the inner refrigerant pipe and thus reducing its impact on the cooling effect.

[0020] In this embodiment, a refrigeration unit 8 is also included. The outlet end of the refrigeration unit is connected to the refrigerant inlet through a refrigerant delivery pipe, and the refrigerant outlet is connected to the inlet end of the refrigeration unit through a refrigerant return pipe. A refrigerant circulation pump 9 is provided on the refrigerant delivery pipe.

[0021] In this embodiment, the inlet end of the material conveying pipeline is connected to the outlet at the bottom of the material storage tank, and a material conveying pump 12 is provided near the inlet end of the material conveying pipeline.

[0022] The system consists of a three-layer casing: a material conveying pipe in the center and two outer refrigerant pipes. Refrigerant cools the material conveying pipe from the inner refrigerant pipe, directly preventing the material from overheating. The refrigerant in the inner pipe flows from its outlet to the outer refrigerant pipe, isolating it from the external environment. Finally, the refrigerant returns to the refrigeration unit from the outlet of the outer refrigerant pipe for further cooling. After cooling, the refrigerant re-enters the inner refrigerant pipe for reuse, creating a refrigerant cycle and reducing costs. This process primarily aims to prevent easily vaporized liquid materials from vaporizing due to high ambient temperatures when passing through exposed pipes during filling, thus ensuring the quality of the filled material.

[0023] Example 2: Figures 3-4 As shown, a jacketed cooling system includes a material storage tank 1 connected to a material conveying pipe 3 leading to a filling device 2. An inner refrigerant pipe 4 is fitted over the material conveying pipe, with both ends of the inner refrigerant pipe sealed and the material conveying pipe exiting from both ends. An external heat insulation layer is provided on the outside of the inner refrigerant pipe. In this jacketed cooling system, the external heat insulation layer provides a certain degree of heat insulation for the material conveying pipe during material conveying, while the refrigerant in the inner refrigerant pipe cools the material conveying pipe, ensuring that the material does not evaporate or generate bubbles due to high temperatures during conveying, thus maintaining the material concentration and product quality. This system can prevent easily vaporized liquid materials from vaporizing due to excessively high ambient temperatures when passing through exposed pipelines during the filling process, thus avoiding any impact on the quality of the filled product.

[0024] In this embodiment, the outer insulation layer is an insulation material 10 that is wrapped around the outside of the internal refrigerant pipe.

[0025] In this embodiment, the insulation material 10 is a PVC heat shrink film, a polyethylene (PE) protective shell, or an aluminum foil composite film.

[0026] In this embodiment, in order to improve production (filling) efficiency, two material conveying pipelines are connected between the material storage tank and the filling equipment. One material conveying pipeline has a refrigerant inlet at the beginning of its internal refrigerant pipeline, and the other material conveying pipeline has a refrigerant inlet at the beginning of its internal refrigerant pipeline. The ends of the internal refrigerant pipelines on the two material conveying pipelines are connected by a connecting pipe 11.

[0027] In this embodiment, a refrigeration unit 8 is also included. The outlet end of the refrigeration unit is connected to the refrigerant inlet via a refrigerant delivery pipe, and the refrigerant outlet is connected to the inlet end of the refrigeration unit via a refrigerant return pipe. A refrigerant circulation pump 9 is installed on the refrigerant delivery pipe. In specific implementation, a single pipeline can also be set up, that is, a material delivery pipeline. The inner refrigerant pipe on the material delivery pipeline has a refrigerant inlet at one end and a refrigerant inlet at the other end.

[0028] In this embodiment, the inlet end of the material conveying pipeline is connected to the outlet at the bottom of the material storage tank, and a material conveying pump 12 is provided near the inlet end of the material conveying pipeline.

[0029] The system consists of two pipelines, A and B, both with a three-layer casing structure. The innermost layer is the material conveying pipeline, the outermost layer is the external insulation layer, and the refrigerant pipeline lies between the external insulation layer and the material conveying pipeline. Refrigerant enters from the inner refrigerant pipeline of pipeline A to cool the product, directly preventing the material from overheating. The outermost insulation layer further controls the temperature of both the refrigerant and the product. The refrigerant then crosses over to the inner refrigerant pipeline of pipeline B, directly cooling the material within pipeline B. The refrigerant exits from the refrigerant outlet of pipeline B and directly enters the refrigeration unit for further cooling. After cooling, it enters the refrigerant inlet of pipeline A, allowing for refrigerant reuse and reducing costs. This system prevents easily vaporized liquid materials from vaporizing due to high ambient temperatures when passing through exposed pipelines during the filling process, thus avoiding impacts on product quality. Furthermore, the dual-pipeline setup improves production efficiency.
