Description

Technical Field

[0001] The invention belongs to the technical field of earthquake monitoring, and in particular relates to a condensing device for cooling hot spring well gas for earthquake precursor observation. Background Art

[0002] Earthquake disasters can bring great disasters and immeasurable economic losses to mankind, so earthquake prevention, prediction and monitoring are extremely important. Monitoring the dynamic changes of gas in groundwater is one of the important means of monitoring underground fluid earthquake precursors, especially the dynamic changes of hot spring well overflow gas. Since the temperature of hot spring well overflow gas is relatively high, some can reach 90°C, it cannot be directly measured by the instrument. The overflow gas needs to be cooled and pre-treated before it can be measured.

[0003] Most of the earthquake monitoring sites are located in remote places without mains electricity. High-power refrigeration equipment such as air compressors are not suitable for cooling hot spring well gas. At present, the cooling of hot spring well overflow gas (referred to as hot spring well gas) still adopts the traditional laboratory glass condenser cooling method. Because glass is fragile and the cooling effect is not ideal; in addition, glass has adsorption to the gas to be measured, which affects the accuracy of the measurement results.

[0004] Therefore, there is an urgent need in the art to develop a condensing device suitable for cooling hot spring well gas for earthquake precursor observation. Summary of the invention

[0005] Based on the above-mentioned shortcomings and deficiencies in the prior art, one of the objects of the present invention is to at least solve one or more of the above-mentioned problems in the prior art. In other words, one of the objects of the present invention is to provide a condensing device for cooling the hot spring well gas for earthquake precursor observation that meets one or more of the above-mentioned needs.

[0006] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:

[0007] A condensing device for cooling hot spring well gas for earthquake precursor observation, comprising a condensing main unit and a spray water circulation system;

[0008] The condensing main unit comprises a shell and a condensing tube, a flexible cooling sheet and a radiator installed in the shell. The condensing tube comprises a spiral section and a gas-liquid separation section extending vertically. The top of the spiral section is provided with an air inlet. The air outlet at the bottom of the spiral section is connected to the gas-liquid separation section. The top and bottom of the gas-liquid separation section are provided with an exhaust hole and a liquid discharge hole respectively. The exhaust hole is located above the exhaust hole, and the liquid discharge hole is located below the exhaust hole.

[0009] The flexible cooling sheet is arranged between the condenser tube and the radiator, the cold surface of the flexible cooling sheet is in contact with the condenser tube, and the hot surface of the flexible cooling sheet is in contact with the radiator;

[0010] The condensing main unit also includes a spray head located inside the shell, which is used to spray and cool the condensing tube;

[0011] The spray water circulation system is used to circulate the water sprayed from the spray head to the spray head.

[0012] As a preferred solution, the condenser is made of graphene material, and its inner wall is coated with a polytetrafluoroethylene film layer.

[0013] As a preferred solution, the inner wall of the condenser tube is provided with a heat dissipation strip extending obliquely toward the inner cavity thereof.

[0014] As a preferred solution, the heat dissipation strip extends upwardly at an inclination angle of 30 to 60 degrees.

[0015] As a preferred solution, the spray head sprays and cools the inner side of the vortex of the spiral section of the condenser tube.

[0016] As a preferred solution, the inner diameter of the spiral section of the condenser tube decreases linearly in the vertical direction.

[0017] As a preferred solution, a heat dissipation fan is installed on one side of the housing, and a heat dissipation vent is provided on the other side opposite thereto.

[0018] As a preferred solution, the bottom of the housing has a water outlet;

[0019] The spray water circulation system includes a water tank, a filter, a water pump and a return pipe. The water tank is connected to the water outlet of the shell through a water inlet pipe, a filter is installed on the water inlet pipe, the water tank is connected to the spray head through a return pipe, and a water pump is installed on the return pipe.

[0020] As a preferred solution, the housing is equipped with a solar panel, which is electrically connected to a water pump and a cooling fan.

[0021] As a preferred solution, there are two flexible cooling sheets, which are respectively installed at the upper middle part and the lower middle part of the spiral section of the condenser tube; the gap between the condenser tube and the radiator is filled with thermal insulation cotton.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The spiral section of the condenser tube of the present invention increases the cooling air path and increases the friction resistance between the spray water and the condenser tube, thereby greatly improving the cooling effect;

[0024] (2) The present invention uses corrosion-resistant, low-adsorption polytetrafluoroethylene film as the inner film of the condenser, which reduces the adsorption of gas by the condenser pipeline and improves the measurement accuracy.

[0025] (3) The cooling sheet used in the present invention is a flexible cooling sheet, and the flexible design fits the condenser tube better; two flexible cooling sheets are installed at the upper middle end and the lower middle end of the condenser tube respectively, so that the condenser tube is cooled more evenly. Under the premise of the same cooling effect, the required power is lower.

[0026] (4) The present invention adopts a dual condensation method of spray water cooling and refrigeration plate refrigeration to improve the condensation effect. At the same time, the condenser tube is sprayed with water liquefied from the condenser tube, which effectively recycles and reuses water resources and saves water resources.

[0027] (5) The present invention uses solar energy for power supply, which solves the problem of monitoring the dynamic changes of hot spring well gas in remote areas without city electricity. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Figure 1 and 2 As shown, the condensing device for cooling the hot spring well gas for earthquake precursor observation according to the embodiment of the present invention includes two major parts: a condensing main unit and a spray water circulation system.

[0033] Specifically, the condensing host includes an outer shell 1 and a condensing tube, a flexible cooling sheet 3, and a radiator 4 installed inside the outer shell.

[0034] The condenser includes a vertically extending spiral section 2-1 and a gas-liquid separation section 2-2, the top of the spiral section is provided with an air inlet 21, the air outlet 22 at the bottom of the spiral section is connected to the gas-liquid separation section, the top and bottom of the gas-liquid separation section are respectively provided with an exhaust hole 23 and a drainage hole 24, the exhaust hole 23 is located above the exhaust hole and extends to the outside of the top wall of the shell, and the drainage hole 24 is located below the exhaust hole and extends to the outside of the bottom wall of the shell. The spiral section 2-1 is tightly coiled in the middle of the inner cavity of the shell in a spiral vortex shape, and the inner diameter of the spiral section 2-1 decreases linearly in the vertical direction to increase the contact area between the spray water and the condenser tube; the outer wall of the spiral section 2-1 is in close contact with the cold surface of the flexible cooling sheet 3, and the hot surface of the flexible cooling sheet 3 is in close contact with the radiator 4; the flexible cooling sheet 3 has two pieces, which are respectively tightly installed around the upper and lower middle parts of the spiral section 2-1, and the flexible cooling sheet is in close contact with the condenser tube through high-temperature thermal conductive silicone grease; the other gaps between the condenser tube and the radiator are filled with thermal insulation cotton to keep the condenser tube warm. In addition, the bonding area with the radiator 4 and the flexible cooling sheet 3 has a boss to further increase the filling thickness of the thermal insulation cotton.

[0035] The hot spring well gas enters the condenser through the air inlet 21, and the gas spirals downward from top to bottom along the gas path inside the condenser, and is finally discharged through the exhaust hole 23 and enters the gas detector.

[0036] The condenser is made of graphene, which has a higher thermal conductivity than metal. Graphene has a higher thermal conductivity than metal and has a better cooling effect on hot spring well gas. A layer of 500nm-10μm corrosion-resistant, low-adsorption polytetrafluoroethylene film is coated inside the condenser to avoid the adsorption of the gas sample by the condenser pipe, making the measurement result more accurate. In addition, a multi-layer heat dissipation strip 20 with an upward inclination of 30-60 degrees is arranged inside the condenser. Figure 3 As shown, the contact surface between the hot spring well gas and the condenser pipe is further increased to improve the cooling effect.

[0037] A spray head 5 is installed in the housing 1, and the spray head 5 is located at the top center of the spiral section of the condenser tube.

Among them, a plurality of heat dissipation vents 1A with a width of 2 to 5 mm are provided on the right side of the housing 1, and a plurality of heat dissipation vents 1B with a width of 2 to 5 mm are also provided on the left side of the housing 1, which serve as air inlets and outlets respectively; accordingly, a heat dissipation fan 6 is installed on the inner wall of the right side of the housing 1, and the wind direction faces the radiator 4, blowing the heat of the radiator 4 to the outside of the housing.

[0038] A display panel 7 is installed on the front side of the housing 1 for displaying the current refrigeration temperature of the condensing device.

[0039] The bottom of the housing 1 is provided with a water outlet, which is integrated with the drainage hole 24 and is used to discharge the condensed water of the hot spring well gas, the liquefied water on the outer wall of the condenser tube and the spray circulating water.

[0042] In addition, solar panels can be installed on the outer shell. The solar panels can be electrically connected to components that require power, such as water pumps, display panels, and cooling fans, to achieve on-site power supply, solving the problem of monitoring the dynamic changes of hot spring well gas in remote areas without city electricity.
