Technical Field

The invention relates to the technical field of heat preservation devices, in particular to a flexible pipeline winding type heat preservation device.

Background

The heat preservation is a scientific and efficient energy-saving technical measure, and can slow down the heat dissipation and conduction speed. The heat preservation means that a heat preservation layer is laid on the surfaces of the heat supply pipeline and accessories thereof, so that the ineffective heat loss of the heat medium in the conveying process is reduced, and the heat medium is kept at certain parameters to meet the requirements of users.

In order to ensure the normal operation of water treatment equipment in alpine regions at low temperature, the anti-freezing technology and equipment of the water treatment equipment need to be developed. The flexible pipeline is designed and wound on the water treatment equipment, and is coated with a heat insulating material, so that the aim of preventing freezing and preserving heat of the equipment is fulfilled. Because the supply of electric power and other forms of energy in alpine regions falls behind, the land is wide and sparse, no electric power facility exists, and the power is generally supplied by a small solar panel, the condition that the water treatment equipment is prevented from freezing by adopting modes such as electric heat tracing or steam heat tracing cannot be achieved, the normal operation of the water treatment equipment cannot be guaranteed, and the water treatment equipment is easy to damage.

Therefore, it is desirable to design a flexible pipeline winding type thermal insulation device.

The scheme selects the phase-change heat storage material as the heat storage and heat transfer medium in the pipeline, and a large amount of heat insulation material is wrapped outside the pipeline, so that the pipeline has the effect of keeping unfreezing for 5-7 days in a low-temperature environment by heating once.

The purpose of this experiment is to explore the best flexible pipeline combination mode according to the melting degree of the phase-change material. The optimal thickness of the casing pipe wall and the diameters of the inner pipe and the outer pipe are selected. The requirements of good flexibility, easy winding, uniform melting of low-temperature phase-change paraffin, difficult waste of heat and the like are required to be met.

Experimental equipment

The device comprises a heat-shrinkable tube, low-temperature phase-change paraffin wax at 30 ℃, a plastic small bag 2.5 inches of a plastic white water belt, a silicone tube with the inner diameter of 10mm and the wall thickness of 2mm, a silicone tube with the inner diameter of 8mm and the outer diameter of 10mm, a plastic water pipe with the outer diameter of 16mm, an alcohol heater, an art designing knife, an insulating adhesive tape, a raw adhesive tape and a special PVC pipeline adhesive funnel.

Uniformly arranging the small bags in the tube band, sealing the tube band by using an insulating adhesive tape, and simultaneously sealing a temperature sensor in the tube band. Hot water of about 60 ℃ is poured into the funnel, the melting condition of the phase-change paraffin is observed, and the temperature is recorded. The inner tube selects a silicone tube with an inner diameter of 10mm and an inner diameter of 8mm to compare and record data respectively. The second step is to verify the heating effect of the internally-communicated heat pipe of the plastic water pipe. Silica gel tubes with the inner diameter of 10mm and the inner diameter of 8mm are respectively led into the plastic water pipe with the outer diameter of 16mm to be used as heat conduction tubes.

TABLE 1 pipeline combination property analysis table

To sum up, the 20mm water pipe and the 8mm heat conduction pipe are selected to be combined and matched as the pipeline of the experiment.

(2) Flexible pipeline winding mode contrast experiment (determining spacing)

Purpose of experiment

The purpose of this experiment was to perform flexible winding based on the pipeline combination obtained in the experiment (1) and to explore the best winding method.

Experimental equipment

The equipment's flexible pipeline, water treatment facilities analogue means, polyurethane foaming glue, PVC pipeline viscose, manual saw, pistol drill, temperature sensor, refrigerator, electronic scale, filter core analogue means.

Procedure of experiment

There are a total of four steps in this experiment. The first step is to assemble the water treatment equipment simulator, and reduce the original cylindrical water treatment equipment with the diameter of 20cm and the height of 60cm according to the proportion of 1: 0.5. A PVC water supply pipe with the diameter of 10cm is used, two ends of the PVC water supply pipe with the length of 30cm are cut and are adhered by adopting a PVC pipeline adhesive tape through plugs, the effect of no water leakage is achieved, and a temperature sensor is sealed in the PVC water supply pipe during adhesion. The second step is to use a mold to make the base using the optimum thickness of polyurethane foam. And coating polyurethane foaming glue on the whole. The third step is to dig grooves on the wrapped foam adhesive according to different winding modes and inlay the assembled flexible pipelines into the grooves. And placing a temperature sensor between the pipelines, and filling the grooves by using polyurethane foaming glue again. And hot water is introduced into the outside to heat the low-temperature phase-change paraffin, and after the heating temperature is reached, the external pipeline is sealed by polyurethane foaming glue. The fourth step is to place the whole device in a refrigerator with an internal temperature of-20 ℃ and record the temperature change. And (4) performing multiple tests to obtain the optimal winding interval and winding mode.

Results and analysis of the experiments

Experiments were performed with three different spacing schemes, 0mm at intervals, 0.5cm at intervals, and 1cm at intervals. The more intensive the arrangement, the faster the water temperature rises, the polyurethane needs to be completely removed when the most intensive arrangement mode is adopted, so that the heat transfer is too fast, the water temperature rises rapidly, and the aim of slow heat absorption cannot be well fulfilled, and when the interval is 0.5cm and the interval is 1cm, the heat dissipation speed is ideal because the polyurethane is used for blocking, but more phase-change materials can be stored at the interval of 0.5cm in comparison with the heat dissipation speed, so that the heat preservation performance is better.

In summary, the scheme of 0.5mm spacing is selected.
