Abstract

The present invention discloses a gas humidity removal device, which mainly comprises a body filled with a cooling liquid medium, an evaporator immersed in the cooling liquid medium and a gas pipeline immersed in the cooling liquid medium. The gas pipeline has at least one air inlet, at least one air outlet and a water outlet. When the evaporator cools the cooling liquid medium to a predetermined temperature, the humid air flowing in the gas pipeline will condense water droplets flowing down along the pipe wall and then be discharged, thereby reducing the humidity of the gas flowing in the gas pipeline.

Description

Humidity removal device for gas

technical field

The invention relates to a gas humidity control device, in particular to a gas humidity removal device.

Background technique

As shown in Figure 1, there is an existing gas humidity removal device, which mainly flows the circulating gas 1 through a low-temperature evaporator 2, so that the moisture contained in the gas condenses into water droplets, and then drips freely. Fall and collect the discharge, so as to achieve the effect of dehumidification.

The above-mentioned dehumidification method is widely used, but it is only limited to the general natural environment. If it is applied to the environment with high humidity, it will have the following defects:

1. High humidity The moisture attached to the evaporator 2 is relatively increased, and it is often in the environment, and the suspended particles are attached to the surface of the evaporator 2, causing the condensed water to stay on the surface of the evaporator 2 for a longer time, and the low temperature state is easy Once it freezes, not only the dehumidification effect will be reduced but also the gas path will be easily blocked. After a vicious cycle, the entire evaporator will form a large ice block that is completely blocked and lose the dehumidification effect.

2. When the evaporator 2 freezes, the whole system will be unbalanced, that is, the load of the compressor for compressing the cold coal will increase, and the operating current will increase relatively, which will not only form virtual work, but also delay the evaporation of the refrigerant, causing the compressor to break down. Ice will cause the compressor to run insufficiently lubricated and burn the coil, causing the system to shut down.

3. When the evaporator 2 is frozen, the system needs to be completely melted to restart the system, which is time-consuming and the performance cannot be improved.

Contents of the invention

The object of the present invention is to provide a humidity removal device for gas that can produce a gas with a better effect of removing humidity.

The gas humidity removal device of the present invention mainly includes a body, a cooling liquid medium, an evaporator and a gas pipeline. The body has a chamber. The cooling liquid medium is filled in the chamber of the body. The evaporator is installed in the chamber of the body and immersed in the cooling liquid medium, and the cooling liquid medium is lowered to a predetermined temperature. The gas pipeline passes through the chamber of the body and is immersed in a cooling liquid medium, and has at least one air inlet, at least one air outlet and at least one water outlet, and moist air enters the gas pipeline through the air inlet In the process, the condensed water drops flow down along the pipe wall, and then are discharged from the water outlet, and the dry gas is output from the air outlet.

The beneficial effect of the present invention is that: when the evaporator drops the cooling liquid medium to a predetermined temperature, the moist air circulating in the gas pipeline will condense water droplets down the tube wall and then be discharged, thereby reducing The humidity of the gas circulating in the gas line.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

As shown in Figure 2, the first preferred embodiment of the gas humidity removal device of the present invention includes: a body 10, an evaporator 20 installed inside the body 10, and a cooling liquid medium filled in the body 10 30 . A gas pipeline 40 passing through the main body 10 and a water collection dish 50 arranged at the bottom of the main body 10 .

The body 10 has a chamber 11 .

The evaporator 20 is installed in the chamber 11 of the body 10 .

The cooling liquid medium 30 of this embodiment can be water, and it is pre-filled in the chamber 11 of the body 10, and the liquid level is higher than the evaporator 20, so that the evaporator 20 is fully immersed in the cooling liquid medium 30 .

The gas pipeline 40 runs through the body 10, and has an air inlet 41 protruding from the top of the body 10, a gas outlet 42 protruding from the bottom of the body 10, and a gas outlet 42 at the bottom of the body 10. The water outlet 43 on the side. The part of the gas pipeline 40 inside the main body 10 is completely immersed in the liquid surface of the cooling liquid medium 30 , and is in a meandering shape to increase the contact area.

The water collecting dish 50 is arranged below the water outlet 43 of the gas pipeline 40, and has a drain 51, which can make the horizontal liquid level higher than the water outlet 43, and make the water outlet 43 extend In the water.

Thereby, when the evaporator 20 is in operation, the cooling liquid medium 30 can be lowered to a predetermined temperature, and the humid air introduced into the gas pipeline 40 through the air inlet 41 will condense into water droplets when it is cooled, and the water droplets Because of the free fall, it can flow down along the pipe wall of the gas pipeline 40, and then be collected and discharged by the water collecting pan 50, so that the humidity of the gas circulating in the gas pipeline 40 can be reduced, and the dry gas can be discharged from the gas outlet 42. Air. And utilizing the water outlet 43 to extend into the water, it can prevent the dehumidified air from being released from the water outlet 43 .

Compared with the existing gas humidity removal device, the present invention can achieve the following advantages:

1. The evaporator 20 uses the cooling liquid medium 30 as a medium, so the temperature is uniform and the dehumidification effect is good. Not only does it not freeze or block the gas path, but it also has an excellent dehumidification effect.

2. The evaporator 20 operates normally, the power factor of the whole system is high, the life of the compressor (not shown in the figure) can be extended, there will be no loss of virtual work, and the refrigerant can be completely evaporated, and the compressor can run smoothly.

3. When the evaporator 20 does not freeze, it can operate continuously, and the efficiency of humidity removal can be greatly improved.

As shown in Fig. 3 again, the second embodiment of the present invention is substantially the same as the first embodiment, the only difference is that the gas pipeline 40' is in the shape of a straight tube, and also has a protruding outside of the top of the body 10 An air inlet 41', an air outlet 42' protruding outside the bottom of the body 10, and a water outlet 43' located on one side of the air outlet 42'. By using the gas pipeline 40' to cooperate with the body 10 and the evaporator 20, the gas humidity removal effect can also be achieved.
