[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0044] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the embodiment of the utility model, a special gas-water separator for filter press is provided, please refer to Figures 1 to 11 shown.

[0046] The gas-water separator mainly includes structural components such as a tank body 1, a reinforcing plate 2, a collision strip 3, a diverter plate 4, a baffle plate 5, an air filter plate 6 and an air filter 7, wherein the tank body 1 is the main place for gas-water separation, and structural components such as the reinforcing plate 2 and the collision strip 3 are all arranged inside the tank body 1, mainly for improving the effect of gas-water separation.

[0047] Combination Figures 1 to 3 As shown, the side wall of the tank body 1 is provided with an inlet 11, which is a passage for the gas-water mixture to enter the interior of the tank body 1. The inlet 11 is arranged tangentially and obliquely downward along the interior of the tank body 1. This arrangement enables the gas and water to spirally move from top to bottom along the inner wall of the tank body 1 with the help of initial kinetic energy. At the same time, an inlet connection flange 111 is connected to the outer pipe mouth of the inlet 11, which can facilitate the connection of the inlet 11 with other pipelines.

[0048] Combination Figures 1 to 3 As shown, a reinforcing plate 2 is provided on the inner wall of the tank body 1 and at the end of the inlet 11 to receive the impact of gas and water. The length of the reinforcing plate 2 is 1 / 4 of the inner diameter circumference of the tank body 1, the width of the reinforcing plate 2 is greater than the diameter of the inner pipe opening of the inlet 11, and the thickness of the reinforcing plate 2 is the same as the thickness of the tank body 1. Since the gas and water flow rate reaching the inside of the tank body 1 is relatively fast, it can cause a certain impact on the tank body 1, and the reinforcing plate 2 is provided at the inner pipe opening of the inlet 11 to provide certain support and protection for the tank body 1, thereby extending the service life of the gas-water separator to a certain extent.

[0049] Combination Figures 1 to 3 As shown, the inner wall of the tank body 1 is provided with a plurality of groups of vertically arranged collision bars 3, which can be used to collide with the gas and water to reduce the kinetic energy of the gas and water. The collision bars 3 include two groups of long collision bars 31 and six groups of short collision bars 32, wherein the length of the long collision bars 31 is greater than that of the short collision bars 32. Figure 3 As shown, the collision bars 3 are arranged at equal intervals on the inner wall of the tank body 1, wherein two groups of long collision bars 31 are arranged at the inner pipe opening of the inlet 11, and the remaining six groups of short collision bars 32 are arranged in sequence along the inner wall of the tank body 1 in a counterclockwise direction. Figure 2 As shown, the top of the long collision bar 31 is higher than the upper edge of the inlet 11, the bottom of the long collision bar 31 is flush with the bottom of the short collision bar 32, the top of the short collision bar 32 is lower than the lower edge of the manhole 12, and the bottom of the short collision bar 32 is higher than the diverter plate 4. This setting can ensure that both gas and water can be effectively blocked by collision, and at the same time, the collision bar 3 will not interfere with the work of other structural components. The gas and water entering the tank body 1 through the inlet 11 first collide with the long collision bar 31 to reduce kinetic energy, and spiral down along the inner wall of the tank body 1, and then collide with the short collision bar 32 to reduce kinetic energy again, so that the water in the gas-water mixture settles by gravity, achieving preliminary separation of gas and water, and most of the gas-water mixture will fall into the diverter plate 4 below.

[0050] Combination Figure 1 and Figure 8 As shown, a diverter plate 4 is provided at the middle and lower part of the tank body 1, and the outer contour of the diverter plate 4 is conical, similar to an umbrella-shaped structure. Among them, a plurality of edge water outlets 41 are provided around the lower edge of the diverter plate 4, and the edge water outlets 41 are all located between the inner wall of the tank body 1 and the diverter plate 4, and are semicircular. A plurality of circular water outlets 42 are provided on the diverter plate 4 and obliquely above the edge water outlets 41, and the number of circular water outlets 42 is greater than the edge water outlets 41. The diverter plate 4 is provided with a plurality of edge water outlets 41 and circular water outlets 42, which can prevent water from accumulating in the diverter plate 4 and improve the water passing efficiency. When the gas-water mixture passes through the diverter plate 4 with an umbrella-shaped structure, the gas part changes its direction of travel and moves upward due to obstruction, and the water slides down along the plate wall of the diverter plate 4 that is inclined downward, and finally falls into the drain port 13 below through the edge water outlets 41 and the circular water outlets 42.

[0051] Combination Figure 1 As shown, a drain port 13 is provided at the bottom of the tank body 1, and the drain port 13 is a channel for water to leave the tank body 1. The drain port 13 is located below the diverter plate 4, and the water on the diverter plate 4 flows down along the edge water port 41 and the circular water port 42, and finally converges to the drain port 13 under the influence of gravity, and is discharged from the tank body 1 through the drain port 13. At the same time, a drain port connection flange 131 is provided on the drain port 13, which can be used to connect with other pipelines to handle the discharged water.

[0052] Combination Figure 1 and Fig. 9 As shown, a baffle plate 5 is arranged inside the tank body 1 and above the diverter plate 4. The baffle plate 5 is an inverted truncated cone structure, and both the upper and lower surfaces thereof are open. The baffle plate 5 can block a small amount of gas-water mixture that goes up along the inner wall of the tank body, and allows the water to settle by itself due to gravity, while the gas part flows to the gas filter plate 6 above through the middle opening.

[0053] An air filter plate 6 is arranged above the baffle plate 5 and below the air filter 7. The outer contour of the air filter plate 6 is conical. A plurality of circular air filter holes 61 are provided on the air filter plate 6. A plurality of edge air filter holes 62 are provided on the lower edge of the air filter plate 6. The aperture of the edge air filter hole 62 is larger than the aperture of the circular air filter hole 61. The circular air filter hole 61 and the edge air filter hole 62 can filter and block the water, so that the gas partially passes through. The lower edge of the air filter plate 6 is connected to the upper edge of the baffle plate 5. The gas and water enter the air filter plate 6 through the middle opening of the baffle plate 5, and enter the air filter 7 above after being filtered through the circular air filter holes 61 and the edge air filter holes 62 provided on the air filter plate 6.

[0054] Combination Figure 1 and Figure 6 As shown, an air filter 7 is arranged on the upper part of the interior of the tank body 1, wherein the air filter 7 mainly includes structural components such as an air filter cartridge 71, an air inlet plate 72, a screen 73, a spring 74 and an air outlet cover plate 75.

[0055] The air filter cartridge 71 is connected to the top of the tank body 1, and the air filter cartridge 71 is a vertically arranged cylindrical structure as a whole, wherein the bottom end of the air filter cartridge 71 is located inside the tank body 1, and the top end of the air filter cartridge 71 is located outside the tank body 1. An air inlet plate 72 is arranged at the bottom end of the air filter cartridge 71, and a plurality of air inlet holes 721 are provided on the air inlet plate 72, and gas can enter the interior of the air filter cartridge 71 through the air inlet holes 721. The screen 73 and the spring 74 are both arranged inside the air filter cartridge 71, wherein the screen 73 can adsorb and filter moisture, the bottom of the screen 73 is in contact with the air inlet plate 72, the top of the screen 73 is in contact with the bottom of the spring 74, and the top of the spring 74 is in contact with the air outlet cover plate 75, and the screen 73 is fixed by squeezing the screen 73 by the spring 74, so as to prevent the screen 73 from being blown away by the air flow, thereby ensuring the effect of gas-water separation. Combined with Figure 6 and Figure 7 As shown, the top of the filter cartridge 71 is connected to the outlet cover plate 75 via the outlet connection flange 76 and fixed by bolts or other fasteners 78. The outlet cover plate 75 is provided with a plurality of groups of long holes 751, which are arranged at equal intervals. The gas after gas-water separation can be discharged through the long holes 751, and the water is blocked and filtered. Figure 7 As shown, a second sealing gasket 77 is provided between the air outlet cover plate 75 and the air outlet connection flange 76 to ensure a good sealing effect. The air filter 7 uses a spring 74 to squeeze and fix the screen 73. When the screen 73 needs to be inspected and replaced, the spring 74 and the screen 73 can be taken out by loosening the fastener 78 and opening the air outlet cover plate 75. The detachable connection design facilitates the cleaning and replacement of the screen 73.

[0056] Combination Figure 1 and Fig.10 As shown, a manhole 12 is provided on the side wall of the tank body 1. The manhole 12 provided on the side wall can facilitate the staff to inspect and repair the internal structural components of the tank body 1 and replace the accessories to ensure the effect of gas-water separation. Fig.10 and Fig.11 As shown, the manhole 12 is connected to the manhole cover plate 121 through the manhole connecting flange 122 and fastened by bolts and other fasteners. At the same time, a first sealing gasket 123 is provided between the manhole cover plate 121 and the manhole connecting flange 122 to ensure a good sealing effect. When it is necessary to inspect and replace the internal structural components of the tank body 1, the bolts and other fasteners are loosened and the manhole cover plate 121 is opened, and the staff can inspect the internal structure of the tank body 1 through the manhole 12. By setting the manhole 12, it is convenient for equipment fault diagnosis and maintenance.

[0057] The working process of the gas-water separator in the embodiment provided by the utility model is as follows:

[0058] The gas-water mixture enters the tank body 1 obliquely downward through the inlet 11, and the reinforcing plate 2 is impacted by the gas-water mixture. Under the action of centrifugal force, the gas-water mixture is thrown toward the inner wall of the tank body 1, and most of the gas-water mixture spirally moves from top to bottom along the inner wall of the tank body 1, collides with the collision bar 3, and the kinetic energy of the gas-water mixture is reduced. A small amount of gas and water goes up along the inner wall of the tank body 1 and is blocked by the baffle plate 5. The water settles by itself due to gravity, thereby realizing the preliminary separation of gas and water. The water that has undergone preliminary separation flows down through the diverter plate 4 through the edge water outlet 41 and the circular water outlet 42, and finally flows out through the drain outlet 13 at the bottom of the tank body 1. The gas that has been initially separated is reversed through the umbrella-shaped diverter plate 4. The gas part moves upward through the opening of the blocking plate 5 to the air filter plate 6. Water particles are further attached. The gas continues to move upward through the edge air filter holes 62 and the circular air filter holes 61, and finally enters the air filter 7 in a zigzag manner. After multi-stage filtration by the air inlet plate 72, the screen 73 and the air outlet cover plate 75, more than 90% of the gas-water mixture is separated from the gas, the gas purity is significantly improved, and the gas-water separation effect is relatively excellent. At the same time, a manhole 12 is also provided on the side wall of the tank body 1 of the gas-water separator, which is convenient for the staff to timely inspect the internal structural components of the tank body 1, and provides convenience for equipment fault diagnosis and maintenance. The screen 73 is fixed by squeezing with a spring 74 in the air filter 7, which is helpful for cleaning and replacement of the screen 73.
