Description

Technical Field

[0001] This utility model relates to the field of mining compressed air pipeline technology, and in particular to a water vapor condensation device in a compressed air pipeline. Background Technology

[0002] Mining compressed air pipelines are key infrastructure used to transport compressed air in mining operations. They consist of high-strength corrosion-resistant pipes, special joints and valves, and are responsible for providing power to pneumatic equipment (such as rock drills and pneumatic picks). They also have ventilation and dust removal functions. Their design must meet high-pressure sealing, impact resistance and explosion-proof safety standards to ensure efficient and stable underground operations.

[0003] Because the air compressed by the ground air compressor in coal mine contains water vapor, especially during the rainy season when the water vapor content is higher; and because the air temperature rises during compression (e.g., from 20℃ to 80℃) and temporarily remains in a gaseous state, the temperature drops after entering the storage tank or pipeline, and the water vapor condenses into liquid water at the dew point. According to the ideal gas law, the volume of air decreases after compression, and the water content per unit volume increases significantly. The water vapor compressed by the air compressor accumulates in the underground compressed air pipeline due to the temperature difference between the ground and underground over a long period, particularly at U-bends and horizontal sections. This causes corrosion of pipelines and valves, valve leaks, insufficient outlet pressure, and damage to seals, affecting normal underground production and increasing maintenance costs. Therefore, this invention proposes a water vapor condensation device for compressed air pipelines to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a water vapor condensation device for compressed air pipelines. This device connects a cooling steel tank to the compressed air pipeline. When the airflow passes through the large-space tank, the thermal conductivity of the steel and the temperature difference between the top and bottom of the tank condense the water vapor, which is then collected at the bottom of the tank and collected in conjunction with a drain pipe. This effectively improves the problems of water vapor in compressed air causing corrosion of the gate valve and insufficient compressed air outlet pressure.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a water vapor condensation device in a compressed air pipeline, comprising a cooling steel tank and a heat exchange steel pipe, wherein the cooling steel tank is used to connect to the compressed air pipeline, and the outer side of the cooling steel tank is provided with heat exchange pleats, wherein multiple sets of heat exchange pleats are provided at equal intervals, and the heat exchange steel pipe is provided on the cooling steel tank at a position between two adjacent sets of heat exchange pleats, and the heat exchange steel pipe is a hollow tube extending into the interior of the cooling steel tank;

[0006] A drain pipe is provided on one side of the bottom of the cooling steel tank, and a gate valve is provided on the drain pipe.

[0007] A further improvement is that: an air inlet connection pipe is provided on one side of the cooling steel tank, and an air outlet connection pipe is provided on the other side of the cooling steel tank. Both the air inlet connection pipe and the air outlet connection pipe are welded and sealed to the cooling steel tank.

[0008] A further improvement is that the outer ends of both the air inlet connection pipe and the air outlet connection pipe are equipped with flanges, and both the air inlet connection pipe and the air outlet connection pipe are connected to the compressed air pipe through flanges.

[0009] A further improvement is that a funnel is provided on one side of the bottom of the cooling steel tank, and the drain pipe is connected to the lower end of the funnel.

[0010] A further improvement is that at least three sets of heat exchange steel pipes are provided at the position between two adjacent sets of heat exchange folds, and the three sets of heat exchange steel pipes are arranged at equal included angles around the center of the cooling steel tank.

[0011] A further improvement is that the outer end of the heat exchange steel pipe is open, and the inner ends of the three sets of heat exchange steel pipes at the same position are connected and closed to each other.

[0012] A further improvement is that: the inner side of the heat exchange steel pipe is provided with heat-conducting plates, and at least four sets of heat-conducting plates are provided around the center of the heat exchange steel pipe at equal angles.

[0013] A further improvement is that: the inner side of the heat exchange folds is provided with reinforcing ribs, and multiple sets of reinforcing ribs are provided at equal included angles around the center of the cooling steel tank.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model connects a cooling steel tank to a compressed air pipeline. When the airflow passes through the large-space tank, the thermal conductivity of the steel and the temperature difference between the top and bottom of the tank are used to condense the water vapor. The condensate is collected at the bottom of the tank and collected with the drainage pipe. The processing cost is low, the difficulty is low, and the installation is convenient. By installing multiple sets of cooling steel tanks of different sizes along the same pipeline, a multi-stage condensation effect can be achieved, which can effectively improve the problems of water vapor in the compressed air causing corrosion of the gate valve and insufficient compressed air outlet pressure.

When the airflow passes through the large-space tank, the thermal conductivity of the steel and the temperature difference between the top and bottom of the tank condense the water vapor, collecting the condensate at the bottom of the tank and collecting it with the drain pipe 4.

[0027] A funnel 9 is provided on one side of the bottom of the cooling steel tank 1, and the drain pipe 4 is connected to the lower end of the funnel 9.

[0029] Example 2

[0030] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a water vapor condensation device in a compressed air pipeline, including a cooling steel tank 1 and a heat exchange steel pipe 3.

[0033] The heat exchange pleats 2 are provided with reinforcing ribs 11 on their inner side, and multiple sets of reinforcing ribs 11 are arranged at equal included angles around the center of the cooling steel tank 1.
