Detailed Description

The principles and features of this invention are described below in conjunction with examples, which are set forth to illustrate, but are not to be construed to limit the scope of the utility model.

As shown in fig. 1-5, a high-efficiency gas-liquid separator comprises a cylinder body 1, wherein the cylinder body is provided with a gas inlet 2, a gas outlet 3 and a sewage discharge outlet 4, and further comprises a first filter arranged in the cylinder body, the first filter comprises a wire mesh separation part, a blade separation part and a liquid discharge pipe, the wire mesh separation part comprises a wire mesh 5, the blade separation part comprises a plurality of blades 6, the plurality of blades are vertically arranged, and a medium flowing gap is formed between every two adjacent blades.

The filter also comprises a second filter, wherein the second filter comprises a separation baffle plate 9, and the separation baffle plate 9 is arranged at the outlet end of the air inlet pipe. In the middle of the gaseous separator that gets into from gas inlet 2 of inclusion liquid, through the baffling board that the side direction was arranged, make gaseous entering into the separator along the tangential direction of 1 inner walls of barrel inside, because gaseous tangential entering can form a cyclone's effect, mix with like this in gaseous a small amount of liquid can filter out partly because of inertia ratio first, directly discharge by drain 4 of separator bottom, further improve the separation precision and the separation efficiency of separator.

Still including setting up the third filter between first filter and the second filter, the third filter includes filter screen 10, filter screen 10 with barrel 1 is connected. The gas after the primary filtration is mixed with a trace amount of solid and liquid, the gas continuously moves upwards and enters a preposed filter screen 10 with a large number of holes, the vaporous liquid mixed in the gas can collide with the filter screen 10 with the holes along with the airflow when moving upwards, and the liquid can be separated when colliding with the filter screen 10 due to the small holes and is attached to the filter screen 10 to naturally drop after forming liquid drops, and is discharged from a drain outlet 4 at the bottom of the barrel body 1, and other liquid can continuously move upwards through the small holes and enters a first filter to be separated.

The separation baffle 9 is obliquely arranged at the outlet end of the inlet pipe. The included angle between the baffle plate and the vertical plane where the axis of the cylinder 1 is located is 5-85 degrees. The baffle plate provides an initial separation effect, and can well filter partial liquid under the action of gravity.

The sectional area of the outlet of the air inlet pipe is larger than or equal to that of the inlet of the air inlet pipe. Gas enters from the gas inlet and then flows to the separation baffle plate, and the size of the outlet can meet the requirement of the separation efficiency of the gas-liquid separator.

The silk screen separating part and the blade separating part are connected with the cylinder body 1 through connecting plates. The connection of the silk screen separation part and the blade separation part with the inner wall of the cylinder body is realized through the connecting plate, so that the installation and the positioning of the separation parts are realized.

The connecting plate comprises an upper cover plate 7 and a lower cover plate 8, and a side plate frame 11 is further arranged between the upper cover plate and the lower cover plate. Through the upper cover plate connection between the upper portion of silk screen separation portion and blade separation portion and the barrel, through lower cover plate connection between the lower part of silk screen separation portion and blade separation portion and the barrel, in order to further increase connection stability and joint strength between the upper and lower apron, still set up the curb plate frame, apron middle part position about the curb plate frame supports neither influences the gas flow, can also further support the stability between the upper and lower apron simultaneously.

The vane separator is disposed adjacent to the gas inlet 2. Blade 6 is being close to gas outlet 3 department, and silk screen 5 is being kept away from gas outlet 3 position, and gas is earlier through silk screen 5, and silk screen 5 filter fineness is high, can separate out most solid particle and liquid in the gas, and blade 6's filter fineness is low, but its filter efficiency is high, guarantees filter efficiency when guaranteeing filter fineness, and in addition, silk screen 5 is convenient for maintain it in the outside.

The wire mesh 5 and/or the blade 6 are connected to the connection plate by means of a support frame 15. In order to further ensure the installation stability of the screen 5 and the blades 6, the screen 5 is installed on the supporting frame 15, the blades 6 are installed on the supporting frame 15, and the supporting frame 15 is connected with the cylinder 1 through the upper and lower cover plates 8.

The lower part of the drain pipe 12 is connected to the cylinder 1 through a drain pipe support 13. The discharge pipe 12 is elongated and guides the separated liquid to the drain outlet 4 at the bottom of the cylinder 1, and the lower part of the discharge pipe 12 is connected and positioned with the cylinder 1 in order to ensure the supporting strength and the mounting stability of the discharge pipe 12.

A manhole 14 for maintenance is further arranged on the cylinder body 1. The separation equipment is provided with a manhole 14, and when the year reaches the maintenance year due to a long time, the inner silk screen 5 can be taken out through the manhole 14 to be replaced.

The screen and the multi-blade matched filter can be integrated together by a frame structure through the tight combination of the screen and the multi-blade matched filter, so that the volume of the separation container is reduced, and if the screen and the blade filtering structure are independently arranged, the height and the diameter of the separation container are increased, so that the separator is large and heavy and has high cost. In addition, the effect of the separator which uses the wire mesh or the blade alone is not good, because the wire mesh has high filtering precision but low filtering efficiency; the efficiency of the blade is high but the accuracy is low. The filter formed by the wire mesh and the blades can exert the advantages of the wire mesh and the blades without increasing excessive cost and the size of the container.

The specific separation process, this vapour and liquid separator's a heavy filtration adopts the separation baffling board, and the import separation baffling board provides preliminary cyclone effect, and under the effect of gravity, the great solid particle of filtration that can be fine, the baffling board that the slope was arranged can reach cyclone's effect. The second filtration is realized by a preposed filter screen, the principle is also that the most of the vaporous liquid is separated out through small holes on the filter screen by inertia separation; triple filtration is realized by silk screen blade combination filter, and most liquid phase components all can be filtered away by the silk screen, and filter effect and precision this moment have reached fine effect. The last blade removes the foam and sets up for further improving filtration accuracy and efficiency, and remaining trace liquid can be further filtered out under the separation effect of a large amount of overlapping blades, makes the filter effect reach the optimum. The separator adopts triple filtration, and the cost of the filter device of each level is very low, but good separation effect can be achieved. Each separator of this equipment all need not often to be changed because under the effect of first heavy filtration and second heavy filtration separation, the medium that enters into the silk screen has been very clean, and liquid can be through the fluid-discharge tube discharge in the combined frame, can long-term stable good operation like this, need not often change, only need in the same direction as taking when unit overhauls to change down the silk screen through the manhole can.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
