[0021] Figure 3It is a structural schematic view of an embodiment of the gas-liquid separator. DETAILED DESCRIPTION

[0022] Referring to Figure 1 Or Figure 2 The utility model discloses a gas-liquid separation plate, which comprises a plate body 61, and the plate body 61 is provided with a plurality of rows of separation hole groups distributed at equal intervals.

[0023] The upper side of each separation hole 62 is connected with a separation sheet 63, the separation sheet 63 is the same in shape and equal in size with the separation hole 62, the separation hole 62 is in strip structure, and the upper side is the short side of the strip structure. The separation sheet 63 and the separation hole 62 form an acute angle, preferably 30 to 60 degrees, and most preferably the angle between them is controlled to be 45 degrees. In the same row, the two adjacent separation sheets 63 are respectively bent towards the two sides of the plate body 61.

[0024] The separation hole 62 and the separation sheet 63 can be realized by punching process, and the hole punched out is the separation hole 62. A small piece of plate is reserved during the punching process, so that the piece of plate is left on the plate body 61 and forms a 45-degree angle with the separation hole 62. The piece of plate is the separation sheet 63.

[0025] By vertically placing the gas-liquid separation plate, if there are liquid droplets in the gas and the gas flows from bottom to top through the gas-liquid separation plate, the direction of the liquid can be changed by the rapid collision during the flow, so that the liquid drops down. Since the gas speed is fast, the gas part can continue to flow upward, thereby achieving the effect of gas-liquid separation.

[0026] The utility model discloses a kind of gas-liquid separation plate components, which comprises a plurality of above-mentioned gas-liquid separation plate, gas-liquid separation plate is vertically arranged, and a plurality of gas-liquid separation plate is distributed at equal intervals, and the hole position of the separation hole 62 of adjacent two gas-liquid separation plates is distributed staggeredly, can be combined Figure 1 And Figure 2 Compare.

[0027] The utility model discloses a kind of gas-liquid separators, such as Figure 3As shown, the gas-liquid separator comprises a tank body 2, a medium inlet 1, a medium outlet 3 and a liquid discharge pipe 4. Inside the tank body 2, from bottom to top, are sequentially arranged a cyclone separator assembly 5, the above-mentioned gas-liquid separation plate assembly 6 and a gas-liquid separation filter core assembly 7, i.e., the gas-liquid separation filter core assembly 7 is arranged at the upper part of the tank body 2, the gas-liquid separation plate assembly 6 is arranged at the middle part of the tank body 2, and the cyclone separator assembly 5 is arranged at the bottom of the tank body 2. The medium inlet 1 is arranged on the tank body 2 and is at the same height as the air inlet of the cyclone separator assembly 5; the medium outlet 3 is arranged at the top of the tank body 2; and the liquid discharge pipe 4 is connected from two places, one being the bottom of the gas-liquid separation filter core assembly 7 and the other being the bottommost part of the tank body 2.

[0028] The gas-liquid separation filter core assembly 7 comprises a partition plate and a filter core arranged on the partition plate, and the filter core is made of glass fiber material; the cyclone separator assembly 5 and the gas-liquid separation filter core assembly 7 are common structures in gas-liquid separation technology and are well known to those skilled in the art, so they will not be described in detail.

[0029] Based on the above-mentioned structure of the gas-liquid separator, the following flow steps are taken during work:

[0030] 1) After the medium flows into the equipment separation chamber through the medium inlet tangentially, the medium is first subjected to preliminary separation by the cyclone separator assembly, the principle of which is that, in the process of main fluid turning, the liquid droplets entrained in the gas phase are captured by using the inertial collision effect to purify the gas phase or obtain the liquid phase, so that the large liquid droplets and impurities are separated from the gas by gravity through the cyclone structure;

[0031] 2) Then, the medium is subjected to secondary separation by the gas-liquid separation plate assembly, the principle of which is that, when the small liquid droplets pass through the gas-liquid separation plate assembly, they are subjected to impact and return to the special separation sheet of the gas-liquid separation plate, and the small liquid droplets are gathered into large liquid droplets on the surface of the gas-liquid separation plate and fall along the gas-liquid separation plate by gravity;

[0032] 3) Finally, the medium is subjected to tertiary separation by the uppermost gas-liquid separation filter core assembly, the principle of which is that the medium of the filter core has liquid repellency, which can prevent liquid from entering and only allow gas without liquid to pass through, so as to achieve better separation effect and remove small liquid droplets.

[0033] It should be noted that, when using the gas-liquid separation filter core assembly, the liquid and a small amount of solid impurities to be separated and removed are blocked on the inner surface of the filter core. As the impurities on the surface of the filter core increase, a pressure difference will appear between the medium inlet and outlet. When the pressure difference reaches the process requirement, the equipment should be stopped or switched to work on another equipment. When replacing or cleaning, the residual medium in the equipment should be discharged first to ensure that the equipment is in a normal pressure state, and then the upper cover of the equipment is opened to clean or replace the filter core, so that the equipment can continue to work.

[0034] The gas-liquid separator disclosed by the utility model has the following beneficial effects:

[0035] 1) the liquid in the medium can be effectively separated better, and liquid drops of 100 microns, 10 microns and microns can be separated respectively;

[0036] 2) the traditional separation method is replaced by 1-2 mechanical separators + one coalescence separator, and the configuration of multiple equipment is replaced by one equipment, so that space and a large amount of investment are saved, and the industrial value is particularly high for large-scale devices;

[0037] 3) different gas-liquid separation structures can be optimized according to different working conditions, the advantages and disadvantages of the structures are optimized, gas-liquid separation can be more reliable, and the best effect and performance can be achieved. Since the filter element in the gas-liquid separation filter element assembly is made of non-metallic material and has a certain service life, once the gas-liquid separation filter element fails, most of the liquid drops can still be effectively separated under the action of the cyclone separation and the gas-liquid separation plate, and the safe operation of the rear equipment is protected.

[0038] In conclusion, the special gas-liquid separation plate structure provides a new idea for the deflection separation, and greatly improves the gas-liquid separation effect of the medium passing through the structure; the gas-liquid separation plate is arranged in the gas-liquid separator, so that the gas-liquid separator can better perform gas-liquid separation.

[0039] Finally, it should be pointed out that: the above only describes preferred embodiments of the utility model, and is not used to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
