DETAILED DESCRIPTION

[0048] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] like Figure 1-5 As shown, the utility model is a coil structure that utilizes high-temperature steam condensate for secondary heating, including a fan 1, a steam coil 2, a water storage tank 3, a hot water coil 4, a water pump 5, a steam valve group 6, an electric valve 7 and a steam generator 8.

[0050] The steam coil 2 is magnetically attached to the air outlet of the fan 1 to transport high-temperature steam. Specifically, Figure 1 and Figure 2 As shown, one end of the steam coil 2 is connected to the steam outlet of the steam generator 8 through a pipeline, and the other end is connected to the water tank 3 through a pipeline. The steam valve group 6 is fixedly arranged on the connecting pipeline between the steam coil 2 and the water tank 3. The steam valve group 6 can control the flow of steam and hot water by adjusting the opening degree of the valve, and is usually used in steam boilers and steam generating equipment.

[0051] The steam generator 8 is any steam generating device in the prior art. The steam generator 8 is used to generate high-temperature steam. The high-temperature steam is transported to the steam coil 2 through a pipeline. When the fan 1 is working, its air outlet blows air, and the blown air passes through the steam coil 2 and is heated to become hot air. When used in a car test environment chamber, the cabin temperature can be increased. After the steam releases heat in the steam coil 2 and liquefies into water, it reaches the water tank 3 along the pipeline for storage. An insulation layer is arranged on the surface of the water tank 3 to reduce heat loss.

[0052] The hot water coil 4 is magnetically adsorbed on the air inlet of the fan 1, one end of which is connected to the water storage tank 3 through a pipe, and the other end is connected to the water inlet of the steam generator 8 through a pipe. The water pump 5 is fixedly arranged on the connecting pipe between the hot water coil 4 and the water storage tank 3, and is used to pump the liquefied water in the water storage tank 3 into the hot water coil 4. The electric valve 7 is arranged between the water pump 5 and the hot water coil 4, and is fixedly arranged on the connecting pipe between the hot water coil 4 and the water storage tank 3, and is used to control the flow rate of water. When hot water needs to be transported to the hot water coil 4, the electric valve 7 is opened, and the water pump 5 pumps the water in the water storage tank 3 into the hot water coil 4, preheating the wind at the air inlet of the fan 1, so that the wind blown out by the fan 1 is quickly converted into hot air, and the hot water in the hot water coil 4 flows into the water inlet of the steam generator 8 through the pipe after heat exchange.

[0053] In the above structure, the liquefied water in the steam coil 2 is collected by the water tank 3, and the liquefied water in the water tank 3 is pumped to the hot water coil 4 by the water pump 5, so as to preheat the wind at the air inlet of the fan 1, thereby realizing the secondary utilization of the hot water discharged from the steam coil 2, increasing the utilization rate of heat, reducing the amount of steam produced, and saving energy.

[0054] In actual use, the steam generator 8 can be placed on the side of the water tank 3, or it can be set at other locations, such as on the ground, wall, or ceiling. Similarly, the water tank 3 can also be set near the fan 1, such as on the ground, wall, or ceiling, or it can be fixed on the fan 1.

[0055] In order to realize automatic water control, a float valve 9 is arranged in the water tank 3, wherein the float valve 9 and the water pump 5 are electrically connected, and the opening and closing of the water pump 5 are controlled by the float valve 9. The control method is any one of the prior art, such as a float type water pump water level controller disclosed in CN208089520U. The liquid level in the water tank 3 rises and lifts the float valve 9. When it exceeds the preset threshold, the water pump 5 starts to pump hot water into the hot water coil 4. The hot water supply can be controlled by the electric valve 7. The hot water after the heat exchange is completed enters the steam generator 8 for the next circulation.

[0056] During the long-term operation of the equipment, scale is likely to appear in the water tank 3. The scale needs to be settled to prevent the scale from entering the hot water coil 4 and causing blockage. Therefore, a settling inclined tube 10 is fixedly arranged in the water tank 3, wherein the settling inclined tube 10 is arranged below the float valve 9. The settling inclined tube 10 is used to settle scale or other impurities in the water. There is clean water above the settling inclined tube 10 and turbid water below it. The water pump 5 sucks the clean water on the upper layer, which is beneficial to pipeline protection.

[0057] In addition, a hot water inlet 301 and a hot water outlet 302 are provided on the top of the water tank 3, an overflow port 303 is provided on the side of the water tank 3, and a sewage outlet 304 is provided on the bottom of the water tank 3, wherein the hot water inlet 301 is connected to the steam coil 2 through a pipe, the hot water outlet 302 is connected to the water pump 5 through a pipe, the sewage outlet 304 and the overflow port 303 are connected to the same sewage pipe, and the sewage outlet 304 is used to discharge the turbid water in the water tank 3.

[0058] like Figure 3 As shown, both sides of the steam coil 2 are bent in an arc shape toward the direction of the fan 1, and both sides of the hot water coil 4 are bent in an arc shape toward the direction of the fan 1, so that the steam coil 2 and the hot water coil 4 are bent inwardly and are not easily damaged by external forces.

[0059] In the above structure, the steam coil 2 and the hot water coil 4 are installed and fixed by magnetic attraction. Specifically, four magnets 11 are respectively arranged at the air outlet of the fan 1 and the air inlet of the fan 1. The four magnets 11 at the air outlet of the fan 1 are arranged in a circular array around the air outlet of the fan 1, and one end of the magnet 11 is magnetically adsorbed on the fan 1, and the other end is fixedly arranged on the steam coil 2. The four magnets 11 at the air inlet of the fan 1 are arranged in a circular array around the air inlet of the fan 1, and one end of the magnet 11 is magnetically adsorbed on the fan 1, and the other end is fixedly arranged on the hot water coil 4. The steam coil 2 and the hot water coil 4 are installed by magnetic attraction, which facilitates the installation and disassembly of the steam coil 2 and the hot water coil 4, facilitates maintenance, is relatively convenient and quick, and is convenient for later installation on the fan 1 that has been put into use.

[0060] The fan 1 will vibrate when working, and these vibrations can easily cause the steam coil 2 and the hot water coil 4 to make noise. To solve this problem, a rubber gasket 12 is fixedly arranged on the end of the magnet 11 close to the fan 1. When installed, the rubber gasket 12 is pressed against the surface of the fan 1 to achieve vibration reduction and noise reduction. Specifically, Figure 4 As shown, the rubber gasket 12 is in a circular ring shape, and the outer diameter of the magnet 11 is larger than the outer diameter of the rubber gasket 12 . The circular ring-shaped rubber gasket 12 is conducive to the magnet 11 magnetically adsorbing the fan 1 .

[0061] The operation logic of the coil structure of the utility model using high-temperature steam condensed water for secondary heating is:

[0062] S1. In the initial state, there is no water in the water tank 3, and the steam is at the rated supply. During the operation of the system, the steam will continuously condense into hot water and be stored in the water tank 3;

[0063] S2, the water level in the water tank 3 is rising continuously until it reaches the preset high liquid point. At this time, the steam supply can be adjusted to start the water pump 5, and the hot water in the water tank 3 is used for secondary heating to preheat the air at the air inlet of the fan 1. The used hot water returns to the steam generator 8 for the next cycle;

[0064] S3. When the liquid level in the water storage tank 3 is lower than the set minimum liquid level, the water pump 5 is turned off, the secondary utilization system is not used, and the steam supply is increased.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
