Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a gas dehumidification device. Background Art

[0002] The gas used in gas boilers has certain requirements for humidity. If the gas humidity is high, more water will enter the burner head, which will cause a series of adverse effects after long-term operation. For example, it will cause the boiler to malfunction and shut down, and even damage the solenoid valve, burn the program controller, etc., which will make later maintenance difficult and time-consuming.

[0003] The Chinese patent with publication number CN209934430U discloses a low-nitrogen boiler flue gas recirculation dehumidifier, which achieves the purpose of dehumidification by arranging a demisting plate in the box to condense and drip water vapor. However, when the above dehumidifier needs to be repaired, the boiler cannot operate normally, resulting in production interruption. Utility Model Content

[0004] The utility model provides a gas dehumidification device, which can not only dehumidify the gas, but also enable the boiler to operate normally during maintenance.

[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, a gas dehumidification device according to an embodiment of the utility model includes a main pipeline 1 and an emergency pipeline 2 arranged in parallel, the main pipeline 1 includes a first pipeline 11, a first valve 12, a separator 13, a second pipeline 14 and a second valve 15, the first valve 12 is arranged on the first pipeline 11, the separator 13 includes a shell 131 and a dehumidifying component 132 arranged inside the shell 131, one end of the first pipeline 11 and the second pipeline 14 are both connected to the shell 131, the second valve 15 is arranged on the second pipeline 14, the emergency pipeline 2 includes a third pipeline 21 and a third valve 22 arranged on the third pipeline 21, one end of the first pipeline 11 away from the shell 131 is connected to the third pipeline 21, one end of the third pipeline 21 is an air inlet 100, the other end of the third pipeline 21 is connected to the second pipeline 14, and one end of the second pipeline 14 away from the shell 131 is an air outlet 200.

[0022] Since the main line 1 and the emergency line 2 are arranged in parallel, when the main line 1 needs to be repaired, the gas path of the main line 1 is cut off by closing the first valve 12 and the second valve 15 and opening the third valve 22, and the gas path of the emergency line 2 is opened to temporarily replace the main line 1 to supply gas, so that the boiler can maintain operation without interruption and delay production. When the main line 1 is repaired, the third valve 22 is closed again, and the first valve 12 and the second valve 15 are opened. The gas passes through the main line 1 for dehumidification before entering the boiler for combustion, avoiding the boiler from malfunctioning due to high humidity of the gas. The dehumidification component 132 is a demister, which can condense the water vapor in the gas and drip it to the bottom of the shell 131, effectively reducing the humidity of the gas.

[0023] Furthermore, the gas dehumidification device further includes a liquid level gauge 3, which includes a liquid level tube 31 and a first connecting tube 32 and a second connecting tube 33 disposed on the liquid level tube 31. The ends of the first connecting tube 32 and the second connecting tube 33 away from the liquid level tube 31 are both connected to the housing 131, and the first connecting tube 32 is located above the dehumidifying element 132, and the second connecting tube 33 is located below the dehumidifying element 132. Since the dehumidifying element 132 can function normally only when the liquid level is below the dehumidifying element 132, the first connecting tube 32 and the second connecting tube 33 are respectively located above and below the dehumidifying element 132, so as to better measure the liquid level.

[0024] By observing the liquid level tube 31, the liquid level inside the housing 131 can be known. When the liquid level inside the housing 131 reaches the position where the first pipe 11 is located, water will flow into the first pipe 11. In this embodiment, the first pipe 11 and the second connecting pipe 33 are both arranged horizontally, and the first pipe 11 is located above the second connecting pipe 33. By controlling the liquid level to a position below the first pipe 11, water can be prevented from flowing into the first pipe 11. At the same time, setting the first valve 12 as a check valve can effectively prevent backflow.

[0025] Furthermore, the first connecting pipe 32 and the second connecting pipe 33 are respectively provided with a fourth valve 34 and a fifth valve 35. When the liquid level pipe 31 needs to be inspected, it is only necessary to close the fourth valve 34 and the fifth valve 35, and no gas leakage will occur, which is easy and safe to operate.

[0026] The bottom of the housing 131 is also provided with a drain pipe 4, and the drain pipe 4 is provided with a drain valve 5. When the liquid level in the housing 131 reaches the upper limit, the drain valve 5 is opened to drain the water inside the housing 131.

[0027] like Figure 1 As shown, the second pipeline 14 is provided with a first pressure gauge 16, which is located at the downstream side of the second valve 15, and the third pipeline 21 is provided with a second pressure gauge 23, which is located at the upstream side of the third valve 22. The first pressure gauge 16 and the second pressure gauge 23 can measure the gas pressure in the second pipeline 14 and the third pipeline 21 respectively. If the reading difference between the first pressure gauge 16 and the second pressure gauge 23 is large, there may be a blockage in the main pipeline 1, which provides a reference for whether to perform maintenance work.

[0028] The second pipeline 14 is also provided with a sixth valve 17, and the first pressure gauge 16 is located between the second valve 15 and the sixth valve 17. Once the sixth valve 17 is closed, the gas paths of the main pipeline 1 and the emergency pipeline 2 can be cut off at the same time, thereby realizing rapid cutting off of the gas supply.

[0029] The top of the shell 131 is hemispherical, and one end of the second pipe 14 is connected to the top of the shell 131. The hemispherical top can better gather the gas and smoothly output it through the second pipe 14.

[0030] like Figure 1 As shown, a humidity sensor 18 is provided on the second pipeline 14. By providing the humidity sensor 18, the humidity of the gas can be detected. If it is found that the gas dehumidified by the main pipeline 1 still has too much humidity, the main pipeline 1 should be repaired.

[0031] Specifically, the humidity sensor 18 is disposed near the gas outlet 200. The humidity sensor 18 can detect the humidity of the gas passing through the main pipeline 1 as well as the humidity of the gas passing through the emergency pipeline 2, that is, it can test the dehumidification function of the main pipeline 1 and determine whether the dehumidification function of the main pipeline 1 is normal.

[0032] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
