Description

Technical fields:

[0001] This utility model relates to the field of oil-gas separation technology, specifically to an oil-gas separation device. Background technology:

[0002] Centrifugal compressors are a widely used type of compressor in methanol production. They achieve gas compression by utilizing centrifugal force. Specifically, after the gas is introduced into the compressor, it rotates continuously under the action of centrifugal force, and its kinetic energy is gradually converted into compression energy, thereby achieving gas compression.

[0003] The current problem is that the centrifugal compressor leaks at the exhaust port during operation, resulting in the discharge of a large amount of flue gas. Due to the high oil content in the flue gas, it is prone to combustion and explosion when exposed to air, which has a serious impact on the surrounding environment and maintenance personnel. Utility model content:

[0004] The purpose of this invention is to provide an oil-gas separation device to solve the problems mentioned in the background art.

[0005] This utility model is implemented by the following technical solution:

[0006] An oil-gas separator includes a support, a cylinder, a tee pipe, a sponge, a flange blind plate, a flue pipe, a steel pipe, a float, a spiral condenser, and a ball valve. The cylinder is fixed to the support. A tee pipe is fixedly connected to the top of the cylinder and filled with sponge. A flange blind plate is installed at one horizontal end of the tee pipe. A flue pipe is inserted into the cylinder, with its inlet end passing through the cylinder. A steel pipe slides through the cylinder, and a float is fixed to the bottom end of the steel pipe, positioned within the cylinder. A spiral condenser is installed within the cylinder, sleeved outside the flue pipe. The inlet and outlet of the spiral condenser are fixed below the cylinder. A ball valve is installed on one side of the bottom of the cylinder.

[0007] Preferably, a partition is fixed in the middle of the cylinder.

[0008] Preferably, a rain cover is welded to the top vertically of the tee pipe.

[0009] The advantages of this invention are: simple structure, effective separation of oil from flue gas for reuse, prevention of oil diffusion into the air, reduction of the possibility of combustion, and reduction of impact on the surrounding environment. Attached image description:

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution for an oil-gas separation device:

[0017] An oil-gas separation device includes a support 1, a cylinder 2, a tee pipe 3, a sponge 4, a flange blind plate 5, a flue pipe 6, a steel pipe 7, a float 8, a spiral condenser pipe 9, and a ball valve 10.

[0018] A cylinder 2 is fixed on the bracket 1. A three-way pipe 3 is fixedly connected to the top of the cylinder 2. The three-way pipe 3 is filled with sponge 4. A flange blind plate 5 is installed at one end of the three-way pipe 3 in the horizontal direction. The sponge 4 can be replaced by removing the flange blind plate 5.

[0019] A flue gas inlet pipe 6 is inserted inside the cylinder 2. The inlet end of the flue gas inlet pipe 6 passes through the cylinder 2. The flue gas inlet pipe can be directly connected to the exhaust port of the centrifugal compressor, so that the leaked flue gas flows into the cylinder 2 through the flue gas inlet pipe 6.

[0020] To accelerate the rapid cooling of oil in the flue gas, a spiral condenser tube 9 is installed inside the cylinder 2. The spiral condenser tube 9 is sleeved on the outside of the flue gas inlet pipe 6. The water inlet and outlet of the spiral condenser tube 9 are fixed at the bottom of the cylinder 2. Cooling water is introduced into the spiral condenser tube 9 to cool the flue gas in the flue gas inlet pipe 6. The flue gas evaporates upward in the cylinder 2. The uncooled oil mist in the flue gas is absorbed and blocked by the sponge 4, realizing oil-gas separation. The blocked oil falls into the cylinder 2 and is collected.

[0021] To facilitate observation of the amount of oil collected inside the cylinder 2, a steel pipe 7 is slidably inserted inside the cylinder 2. A float 8 is fixed to the bottom end of the steel pipe 7. The float 8 is placed inside the cylinder 2 and rises as the oil level increases, causing more and more of the steel pipe 7 to leak out onto the outside of the cylinder 2.

[0022] A ball valve 10 is installed on one side of the bottom of the cylinder 2 for draining the oil collected inside the cylinder 2.

[0023] A baffle 11 is fixed in the middle of the cylinder 2 to prolong the residence time of flue gas in the cylinder 2.

[0024] The top of the vertical direction of the tee pipe 3 is welded with a rain cover 12 to prevent rainwater from entering the cylinder 2.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
