Description

Technical Field

[0001] This utility model relates to the field of chemical equipment, and in particular to a pipeline 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 pipeline 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 pipeline cooling system, including a material storage tank, the material storage tank being connected to a material conveying pipeline leading to a filling device, and also including a first ventilation duct and a second ventilation duct arranged parallel to the material conveying pipeline. The first ventilation duct is sleeved on the material conveying pipeline, and both ends of the first ventilation duct are closed, with the material conveying pipeline passing through both ends of the first ventilation duct. The first ventilation duct is closed at its first end and connected to an air supply device at its last end. An exhaust port is provided at the first end of the first ventilation duct, and the first and second ventilation ducts are connected by several connecting pipes.

[0006] Furthermore, the air supply equipment is a water-cooled air handling unit.

[0007] Furthermore, the connecting pipe is equipped with a regulating ball valve for adjusting the air volume, wherein the two connecting pipes are located at the tail end of the first ventilation duct and the head end of the second ventilation duct, respectively.

[0008] Furthermore, the first and second ventilation ducts are equipped with drain valves and thermometers.

[0009] Furthermore, an exhaust valve is provided at the exhaust port.

[0010] Furthermore, the first end of the material conveying pipeline is connected to the discharge port at the bottom of the material storage tank, and a material conveying pump is provided near the first end of the material conveying pipeline.

[0011] Furthermore, the first ventilation duct, the second ventilation duct, and the connecting pipe are all covered with an insulation layer.

[0012] Furthermore, the insulation layer is made of aluminum foil rubber insulation cotton.

Detailed Implementation

[0020] 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.

[0021] 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.

[0022] like Figures 1-4As shown, a pipeline cooling system includes a material storage tank 1, which is connected to a material conveying pipeline 2 leading to filling equipment (generally a canning truck). It also includes a first ventilation duct 3 and a second ventilation duct 4 arranged parallel to the material conveying pipeline. The first ventilation duct is sleeved on the material conveying pipeline, and its ends are closed, with the material conveying pipeline exiting from both ends. The second ventilation duct is closed at its first end and connected to an air supply device 5 at its last end. An exhaust port is provided at the first end of the first ventilation duct. The first and second ventilation ducts are connected by several connecting pipes 6. In this pipeline cooling system, the airflow direction is opposite to the material flow direction. During material conveying, the first ventilation duct itself provides a certain degree of heat insulation to the material conveying pipeline. Simultaneously, the air in the second ventilation duct enters the first ventilation duct through the connecting pipes to cool the material conveying pipeline, ensuring that the material does not evaporate or generate bubbles due to high temperatures during conveying, thus guaranteeing the material concentration and product quality. This system can prevent liquid vaporization caused by excessively high ambient temperatures when the product passes through exposed pipelines during the material filling process, thus avoiding any impact on the quality of the filled product.

[0023] The reason for setting up a second ventilation duct and several connecting pipes in this system is to ensure that the cooling effect of the entire material conveying pipeline is as uniform as possible, and to avoid the problem that the cooling effect is good at the tail end of the material conveying pipeline and poor at the head end.

[0024] In this embodiment, the first ventilation duct and the second ventilation duct have the same diameter, and the diameter of the material conveying duct is about half the diameter of the first ventilation duct.

[0025] In this embodiment, the air supply device 5 is a water-cooled air cabinet unit, and the air supply temperature of the water-cooled air cabinet unit is 13~18℃.

[0026] In this embodiment, the connecting pipe 6 is equipped with a regulating ball valve 7 for adjusting the air volume. Two connecting pipes are located at the tail end of the first ventilation duct and the head end of the second ventilation duct, respectively, and the remaining connecting pipes are spaced apart in the middle section of the two ventilation ducts. The two ends of the connecting pipes are connected to the first ventilation duct and the second ventilation duct respectively through tee pipes.

[0027] In this embodiment, the first ventilation duct and the second ventilation duct are equipped with a drain valve 8 and a thermometer 9.

[0028] In this embodiment, an exhaust valve 10 is provided at the exhaust port.

[0029] In this embodiment, the first end of the material conveying pipeline is connected to the discharge port at the bottom of the material storage tank, and a material conveying pump 11 is provided near the first end of the material conveying pipeline.

[0030] In this embodiment, the first ventilation duct, the second ventilation duct, and the connecting pipe are all covered with a thermal insulation layer 12.

[0031] In this embodiment, the insulation layer is made of aluminum foil rubber insulation cotton.

Any person skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this utility model discloses only some numerical values ​​to illustrate the technical solutions of this utility model. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this utility model.

[0033] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integral molding process).

[0034] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments.
