Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the field of modern industrial automation, pneumatic devices are the more common control and actuator mechanisms, and compressed air is the cheapest power source. Along with the increasing precision degree of pneumatic equipment, the requirement on a pressure air source is also increased. Currently, air compressors directly draw in air and then compress it, delivering the compressed air to pneumatic equipment. However, the air contains a large amount of water vapor, and particularly when the south is in a rainy season, the humidity of the air can reach over 90 percent, so that the compressed air also contains a large amount of water vapor. Even when a high-power silent air compressor is used, lubricating oil and air are mixed and compressed, so that the compressed air not only contains water vapor, but also oil vapor, and the compressed air contains a large amount of liquid vapor (such as water vapor, oil vapor and the like). After the liquid vapor and the air are compressed together and transmitted to the pneumatic equipment, the liquid vapor is condensed into liquid to cause the pressure control precision of the pneumatic equipment to be reduced, so that the control precision or the execution precision of the pneumatic equipment is reduced, even the oil vapor can block the inlet of the pneumatic equipment, and the service life of the pneumatic equipment is shortened.
Based on this, the present application provides a compressed air dehumidifying apparatus, comprising: the upper cover, the air inlet hole, the air outlet hole, the throttling hole and the condensation cover; the air inlet holes and the air outlet holes are distributed on the upper cover, and the depth of the air inlet holes is greater than that of the air outlet holes; the throttling hole is positioned at the lower end of the condensation cover; the lower end of the upper cover is connected with the upper end of the condensation cover to form a condensation chamber, the condensation chamber is used for storing compressed air entering from the air inlet, gas-liquid separation is realized after the compressed air touches the condensation cover, and separated liquid is discharged from the throttling hole along the condensation cover; and the separated compressed air is discharged from the air outlet hole.
It can be seen that through the technical scheme that provides in this application, after air compressor compressed air, compressed air entered into the condensation chamber from this compressed air dehydrating unit's inlet port, because air compressor does work to the air compression to lead to gaseous internal energy increase, and then the pressure increase in the condensation chamber. The compressed air in the condensing chamber is discharged through the orifice, so that the pressure in the condensing chamber is reduced, and the reduced pressure of the compressed air absorbs heat, thereby causing the temperature of the condensing cover to be reduced. After the compressed air in the condensation chamber touches the lower condensation cover of temperature, the liquid steam in the compressed air can condense to flow out from the orifice along the condensation cover, and the compressed air after the separation is discharged from the venthole simultaneously, thereby realizes gas-liquid separation. The compressed air from which the liquid vapor is removed is input into the pneumatic equipment, thereby not only preventing the control accuracy or execution accuracy of the pneumatic equipment from being lowered, but also preventing the service life of the pneumatic equipment from being shortened.
The compressed air dehumidifying apparatus provided by the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic sectional view of a compressed air dehumidifying apparatus according to the present application.
This compressed air dehydrating unit includes: upper cover 101, air inlet hole 102, air outlet hole 103, throttle hole 104 and condensation cover 105.
Wherein, the air inlet hole 102 and the air outlet hole 103 are distributed on the upper cover 101, the upper ends of the air inlet hole 102 and the air outlet hole 103 are on the same horizontal plane with the upper end of the upper cover 101, the lower end of the air inlet hole 102 extends into the condensing chamber 106, the lower end of the air outlet hole is on the same horizontal plane with the lower end of the upper cover 101, namely the depth of the air inlet hole 102 is larger than that of the air outlet hole 103.
The lower end of the upper cover 101 is covered on the upper end of the condensation cover 105, and both form a condensation chamber 106. Wherein, the condensation chamber 106 is used for storing the compressed air entering from the air inlet 102, when the compressed air touches the condensation cover 105, the liquid vapor in the compressed air can be condensed due to the lower temperature of the inner wall of the condensation cover 105, and thus separated from the compressed air, the separated liquid is discharged from the throttle hole 104 at the lower end of the condensation cover 105 along the condensation cover 105, and the separated compressed air is discharged from the air outlet 103.
It should be noted that the air outlet 103 is located on the upper cover 101, so that the condensed liquid is discharged downward under the influence of gravity, and the separated compressed air is discharged from the air outlet 103 above, thereby further improving the efficiency of gas-liquid separation.
It should be noted that the orifice 104 is a small diameter hole for the condensed liquid to flow out. Meanwhile, due to the high pressure of the condensation chamber 106, compressed air is discharged from the throttle hole 104, so that the discharged air pushes the liquid to flow out and cannot block the throttle hole 104.
As a possible implementation, the orifice 104 may be located at the lowermost end of the condensation cover 105, thereby facilitating the drainage of liquid from the orifice 104 along the inner wall of the condensation cover 105.
As a possible implementation, the cross section of the shape of the condensation cover 105 is U-shaped, so that the condensed liquid is not accumulated at the lower end of the condensation cover 105, but is smoothly discharged from the orifice 104 along the inner wall of the condensation cover 105.
As a possible implementation manner, in order to keep the temperature of the inner wall of the condensation cover 105 from being raised by the external heat, an insulating layer 107 may be wrapped on the outer wall of the condensation cover 105 to prevent the temperature of the inner wall of the condensation cover 105 from being raised, so as to ensure that the liquid vapor can be condensed into liquid when touching the condensation cover 105, thereby achieving gas-liquid separation. It is understood that the insulation layer 107 does not block the throttle hole 104 at the lower end of the condensation cover 105, i.e. the condensation cover 105 except the throttle hole 104 is wrapped by the insulation layer 107.
As a possible implementation manner, in order to make the sealing effect of the condensation chamber 106 better, a sealing ring 108 may be used to seal the connection between the upper cover 101 and the condensation cover 105, so as to ensure that the compressed air in the condensation chamber 106 does not flow out from the position outside the throttle hole 104, and ensure that the pressure of the condensation chamber 106 is higher than the pressure outside the compressed air dehumidification device, thereby ensuring that the temperature of the inner wall of the condensation cover 105 is lower.
As a possible implementation, a sealing ring 108 is screwed to connect the lower end of the upper cover 101 and the upper end of the condensation cover 105, thereby improving the sealing effect of the condensation chamber 106.
Therefore, according to the technical scheme provided by the application, the compressed air dehumidifying device can be installed between the air compressor and the pneumatic device, after the air compressor compresses air, the compressed air enters the condensation chamber from the air inlet of the compressed air dehumidifying device, and the air compressor does work on the air compression, so that the internal energy of the air is increased, and the pressure in the condensation chamber is increased. The compressed air in the condensing chamber is discharged through the orifice, so that the pressure in the condensing chamber is reduced, and the reduced pressure of the compressed air absorbs heat, thereby causing the temperature of the condensing cover to be reduced. After the compressed air in the condensation chamber touches the lower condensation cover of temperature, the liquid steam in the compressed air can condense to flow out from the orifice along the condensation cover, and the compressed air after the separation is discharged from the venthole simultaneously, thereby realizes gas-liquid separation. The compressed air from which the liquid vapor is removed is input into the pneumatic equipment, thereby not only preventing the control accuracy or execution accuracy of the pneumatic equipment from being lowered, but also preventing the service life of the pneumatic equipment from being shortened.
In order to make the technical solutions provided by the embodiments of the present application clearer, the following describes an example of a compressed air dehumidifying apparatus provided by the present application with reference to fig. 2.
The compressed air dehumidifying apparatus further includes a temperature reducing device 109, a controller 110, a first temperature sensor 111, and a second temperature sensor 112.
Wherein, the first temperature sensor 111 may be located on the outer wall of the condensation cover 105 for detecting the temperature of the condensation cover 105 and transmitting the temperature value of the condensation cover 105 to the controller 110. The second temperature sensor 112 may be located outside the compressed air dehumidifying apparatus, such as the upper end of the upper cover 101, or integrated with the controller 110, and detects the temperature of the air outside the compressed air dehumidifying apparatus, i.e., the temperature of the compressed air, and transmits the temperature of the compressed air to the controller 110.
The controller 110 may be located anywhere on the compressed air dehumidifier for calculating the difference between the received temperature of the condenser shroud 105 and the compressed air temperature. When the difference is less than the temperature required for condensation of the separated liquid, the temperature reduction device 109 is turned on so that the temperature reduction device 109 reduces the temperature of the condensation cover 105.
When the pressure of the condensing chamber 106 is relatively low, the pressure difference between the inside and the outside of the condensing chamber 106 is relatively small, and the pressure reduction of the compressed air absorbs less heat, so that the temperature of the condensing cover 105 is not particularly low, and after the compressed air in the condensing chamber 106 touches the condensing cover with relatively low temperature, the condensing condition of the liquid vapor in the compressed air cannot be achieved, so that the condensing efficiency is relatively low, and the gas-liquid separation cannot be realized. Therefore, an auxiliary cooling device is needed to reduce the temperature of the condensing hood 105, so that the liquid vapor in the compressed air can be condensed into liquid, and the gas-liquid separation is realized.
As a possible implementation, referring to fig. 3, the cooling device 109 may be a semiconductor cooling plate 109 a. The semiconductor refrigerating plate, also called thermoelectric refrigerating plate, is a heat pump. When direct current passes through a couple formed by connecting two different semiconductor materials in series, heat can be absorbed and released at two ends of the couple respectively. The heat absorption end of the semiconductor refrigeration piece 109a is connected with the condensation cover 105, and under the condition of direct current flowing through the semiconductor refrigeration piece 109a, the heat of the condensation cover 105 can be transferred to the outside of the compressed air dehumidification device, and the heat is taken away from the external environment, so that the temperature of the condensation cover 105 is reduced, and the auxiliary refrigeration effect is realized.
As a possible implementation manner, a heat sink 109b may be connected to the heat-releasing end of the semiconductor chilling plate 109a, so as to assist the semiconductor chilling plate 109a in dissipating heat.
As a possible implementation manner, the temperature reducing device 109 may be a water cooler, and the heat of the condensation cover 105 is taken away through a water circuit of the water cooler, so as to achieve the effect of auxiliary refrigeration.
As a possible implementation manner, the cooling device 109 may be a freon refrigerator, and the heat of the condensation cover 105 is taken away through the freon circulation, so as to realize the function of auxiliary refrigeration.
Therefore, according to the technical scheme provided by the application, if the pressure in the condensation chamber is low, the pressure difference between the condensation chamber and the outside is small, the air pressure of the compressed air is reduced, the absorbed heat is reduced, and therefore the temperature of the condensation cover is low when the pressure difference between the inside and the outside is large, and the gas-liquid separation efficiency is influenced. This application introduces as heat sink auxiliary cooling, helps the temperature of condensation cover to maintain at the temperature that can support liquid vapor condensation. When the difference in temperature between the inside and outside of the condensation chamber is less than the required temperature difference of liquid steam condensation, the cooling device is opened, after the compressed air in the condensation chamber touches the lower condensation cover of temperature, the liquid steam in the compressed air can condense, and flow out from the orifice along the condensation cover, and the compressed air after the separation is discharged from the venthole simultaneously, thereby realizing gas-liquid separation. The compressed air from which the liquid vapor is removed is input into the pneumatic equipment, thereby not only preventing the control accuracy or execution accuracy of the pneumatic equipment from being lowered, but also preventing the service life of the pneumatic equipment from being shortened.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the apparatus embodiment, since it is substantially similar to the method embodiment, it is relatively simple to describe, and reference may be made to some descriptions of the method embodiment for relevant points. The above-described apparatus embodiments are merely illustrative, and the units and modules described as separate components may or may not be physically separate. In addition, some or all of the units and modules may be selected according to actual needs to achieve the purpose of the solution of the embodiment.
