Description

Technical Field

[0001] The disclosed embodiments relate to the technical field of pipe cooling, and in particular to a spray cooling device for producing spray-wound insulation pipes. Background Art

[0002] Insulated pipe is the abbreviation of insulated pipe. Insulated pipe is used for the transportation of liquids, gases and other media, and is used in thermal insulation projects of pipelines in petroleum, chemical, aerospace, military, central heating, central air conditioning, municipal and other industries.

[0003] Insulated pipes primarily consist of four components: 1. Working Steel Pipe: Depending on the technical requirements of the conveying medium, seamed steel pipe, seamless steel pipe, or double-sided submerged arc spiral welded steel pipe may be used. 2. Insulation Layer: Rigid polyurethane foam is used. 3. Protective Shell: High-density polyethylene or fiberglass reinforced plastic is used. 4. Leakage Alarm Wire: During the manufacture of high-temperature prefabricated direct-buried insulated pipes, an alarm wire is embedded in the insulation layer near the pipe. If a leak occurs somewhere in the pipe, the alarm wire transmits the information, generating an alarm on a dedicated detection instrument that displays the exact location and severity of the leak, allowing maintenance personnel to quickly address the leaking pipe section and ensure safe operation of the heating network.

[0004] In existing technologies, when spraying water to cool insulated pipes, the water spraying rate is often too high, causing the pipe surface to experience significant temperature fluctuations in a short period of time. This not only affects the material properties of the pipe, but also easily causes significant internal stress in the pipe during the cooling process, thus affecting the overall quality and service life of the pipe.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0034] In existing technologies, when spraying water to cool insulated pipes, the water spraying rate is often too high, causing the pipe surface to experience significant temperature fluctuations in a short period of time. This not only affects the material properties of the pipe, but also easily causes significant internal stress in the pipe during the cooling process, thus affecting the overall quality and service life of the pipe.

[0035] In one embodiment, a spray cooling device for spray winding insulation pipe production is provided. Figures 1 to 2 .

[0036] A spray cooling device, cooling system and water supply system for the production of spray-wound thermal insulation pipes.

[0037] Water supply system: This includes a water supply tank for storing and supplying cooling water. Depending on actual needs, the water supply tank can be further divided into a primary and secondary water supply tank, each independently supplying water to the spray mechanism and the mist mechanism to ensure stable and controllable cooling. The water supply tank is equipped with a water level monitoring device to monitor water level changes in real time to ensure adequate water supply.

[0038] The cooling system includes: a cooling room 1, a placement mechanism 2, a spray mechanism, a misting mechanism, and an upper bracket 3 and a lower bracket 4. The placement mechanism 2 is provided in the cooling room 1 and is used to place the insulation pipe; the upper bracket 3 is provided above the cooling room 1, and the lower bracket 4 is provided below the cooling room 1; the spray mechanism includes an upper spray pipe 5 and a first water pump, wherein the upper spray pipe 5, the first water pump, and the water supply tank are connected in sequence; the misting mechanism includes a spray pipe 6 and a spray pump, wherein the spray pipe 6, the spray pump, and the water supply tank are connected in sequence, and the spray pipe 6 includes an upper spray pipe 6 and a lower spray pipe 6.

[0039] The upper spray pipe 5 and the upper spray pipe 6 are alternately installed in parallel on the upper bracket 3, with the nozzles of the upper spray pipe 5 and the upper spray pipe 6 facing downward; the lower spray pipe 6 is installed in parallel on the lower bracket 4, with the nozzle of the lower spray pipe 6 facing upward. Figure 2 , which is a schematic diagram of the upper spray pipe 5 and the upper spray pipe 6 being alternately parallel.

[0040] A placement mechanism 2 is provided inside the cooling room 1 for stably placing the insulation pipes and other equipment to be cooled. A drainage system is provided at the lower end of the cooling room 1 to facilitate the collection and discharge of wastewater generated during the cooling process.

[0041] The spray mechanism consists of an upper spray pipe 5, a first water pump, and connecting piping. Mounted on the upper bracket 3, the upper spray pipe 5 faces downward. The first water pump pumps water from the water supply tank to spray cooling water over the insulation pipe. The spray mechanism consists of a spray pipe 6, a spray pump, and connecting piping.

[0042] The spray pipe 6 is divided into an upper spray pipe 6 and a lower spray pipe 6, mounted on the upper bracket 3 and lower bracket 4, respectively, with the nozzles facing in opposite directions. The upper spray pipe 6 points downward, while the lower spray pipe 6 points upward. A spray pump draws water from the water supply tank and sprays it in a mist, further increasing the cooling area and improving cooling efficiency. To ensure uniform cooling, the upper and lower sprays are applied simultaneously during spray cooling.

[0043] In addition, the cooling room 1 is also provided with a ventilation device to accelerate air flow and take away heat; a lighting device is provided to facilitate operation at night or in insufficient light; universal wheels are provided at the bottom to facilitate the movement and positioning of the device; and an observation window is provided on the side wall to facilitate observation of the cooling process.

[0044] In a preferred embodiment, the spray mechanism is further provided with a lower spray pipe, a second water pump, and corresponding connecting pipes. The lower spray pipe is mounted on the lower bracket 4 or at an appropriate position in the cooling room 1 to spray water below the insulation pipe to enhance the cooling effect. If water pumps of the same power act on the upper spray pipe 6 and the lower spray pipe 6, when the upper spray pipe 5 sprays water downward, the water flow is larger due to the effect of gravity. When the lower spray pipe sprays water upward, the water flow is smaller due to the effect of gravity. Therefore, in order to ensure a uniform cooling effect on the insulation pipe, the power of the second water pump must be greater than that of the first water pump.

[0045] The use process is to check the water level of the water supply tank to ensure that there is sufficient water in the first water supply tank and the second water supply tank to meet the needs of spraying and misting. The insulation pipe to be cooled is placed securely on the placement mechanism 2 of the cooling room 1 to ensure that the insulation pipe is fixed and does not shake, so as to facilitate uniform cooling. Start the spray pump to allow the water in the second water supply tank to pass through the spray pipe 6, including the upper spray pipe 6 and the lower spray pipe 6, and be sprayed out in the form of atomization. Due to the fine particles of the atomized liquid, its cooling capacity is slightly weaker than that of direct water spraying, but the contact area with the insulation pipe is relatively uniform and wide in the initial stage, which can effectively slow down the speed of heat transfer, thereby controlling the cooling speed of the insulation pipe. When the surface temperature of the insulation pipe drops to a certain level and the initial cooling is uniform, start the first water pump to allow the water in the first water supply tank to be sprayed directly onto the insulation pipe through the upper spray pipe 5 and the lower spray pipe in the form of a spray. The sprayed liquid directly impacts the surface of the insulation pipe, increasing the efficiency of heat transfer and accelerating the cooling process. At this stage, the flow rate and spraying time of the spray pump can be adjusted according to the material, initial temperature and cooling requirements of the insulation pipe to ensure that the insulation pipe is evenly and fully cooled.
