[0005] 2. This device requires water treatment to remove oil mist, making subsequent recovery quite difficult. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for recovering oil mist gas.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A device for recovering oil mist gas includes a main tank, on which an oil filter tank is detachably mounted via a connecting frame. An air inlet pipe is bolted to the top of the oil filter tank, and the air inlet pipe is equipped with a fixing flange. A set of replaceable filter elements is also installed inside the oil filter tank. A condensation contact tank is mounted inside the cavity of the main tank via a condensation tank bracket. An exhaust pipe is installed at the end of the main tank. Both the main tank and the oil filter tank are provided with support frames.

[0009] As a further embodiment of this utility model: a first fan is provided at the front end of the oil filter tank, the first fan is located at the axial position of the front end of the oil filter tank, and the first fan has an air intake fan protective cover with a filter element.

[0010] As a further improvement of this utility model: the bottom of the oil filter tank is provided with filter holes, and a filtrate collection tank is installed below the oil filter tank via a slide rail that can be unloaded, with the gap of the filtrate collection tank aligned with the filter holes.

[0011] As a further embodiment of this utility model: a storage tank support is provided on one side of the main tank body by welding, a condensate storage tank is provided on the storage tank support, the condensate storage tank is detachably connected to a condensate valve, and the other end of the condensate valve passes through the main tank body and is connected to the condensate contact tank.

[0012] As a further improvement of this utility model: a row of condensation holes is provided on the bottom inner side of the main tank; a condensation recovery box is placed at the bottom of the condensation holes.

[0013] As a further embodiment of this utility model: the main tank is provided with a second fan bracket at its processing end, the second fan bracket is rotatably mounted with a second fan shaft, and the second fan shaft is provided with a detachable second fan.

[0014] As a further improvement of this utility model, a pressure gauge is also provided on the condensate valve.

[0015] As a further improvement of this utility model, a set of condensation grooves is provided on the inner wall of the main tank.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. By setting up an air inlet pipe and a fixed flange, an external pipeline can be connected to the air inlet pipe to introduce oil mist gas into the device. The filter element can perform initial physical filtration of the oil mist gas, and the condensation contact tank also increases the internal contact area. The exhaust pipe at the end of the tank can discharge the recovered gas from the device.

At the same time, the suction fan protective cover can protect the first fan, and the filter element set in the suction fan protective cover can absorb impurities from the outside air.

[0019] 3. By setting up a filtrate collection tank and filter holes, when oil mist gas enters the oil filter tank, it will first come into contact with the inner wall of the oil filter tank, which may cause larger particles to directly adhere to the inner wall of the oil filter tank; these large particles can be recovered by passing through the filter holes into the filtrate collection tank under the influence of gravity.

[0020] 4. By setting up a condensate storage tank, a condensing gas such as liquid nitrogen can be filled in the condensate storage tank, which can continuously supply condensing gas to the condensation contact tank to ensure the condensation effect. At the same time, the condensate valve can also release the gas in the condensation contact tank in a timely manner through atmospheric pressure.

[0021] 5. By setting condensation holes, the liquid after the oil mist gas is condensed can drip out of the main tank in a timely manner and be collected by the condensation recovery tank. The condensation recovery tank is independent of the whole device and can be replaced at any time, which facilitates the recycling work.

[0022] 6. By setting a second fan bracket, the second fan shaft and the second fan can be installed at the end of the main tank to provide negative pressure, so that the oil mist gas in the main tank can be discharged from the exhaust pipe in a timely manner, thereby achieving an overall recycling and purification process.

[0023] 7. The pressure inside the condenser contact tank can be continuously monitored by setting a pressure gauge.

[0024] 8. By setting up a condensation tank to increase the internal contact area of ​​the main tank, it is beneficial for the oil mist gas to be cooled and turned into liquid. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] Example 1

[0032] A device for recovering oil mist gas, such as Figure 1-3 As shown, the system includes a main tank 1; an oil filter tank 2 is detachably mounted on the main tank 1 via a connecting frame 8; an air inlet pipe 201 is bolted to the top of the oil filter tank 2, and the air inlet pipe 201 is equipped with a fixing flange 202; a set of replaceable filter elements 203 is also installed inside the oil filter tank 2; a set of condensation tanks 101 is provided on the inner wall of the main tank 1; a condensation contact tank 102 is installed inside the cavity of the main tank 1 via a condensation tank bracket 103; an exhaust pipe 5 is installed at the end of the main tank 1; and both the main tank 1 and the oil filter tank 2 are provided with support frames 6.

[0033] In this embodiment, by setting an air inlet pipe 201 and a fixed flange 202, an external pipe can be connected to the air inlet pipe 201 to introduce oil mist gas into the device. The filter element 203 can perform initial physical filtration of the oil mist gas. The main tank 1 is provided with a condensation tank 101 to increase the internal contact area of ​​the main tank 1, which is conducive to the cooling of the oil mist gas into a liquid state. At the same time, the condensation contact tank 102 also increases the internal contact area. The exhaust pipe 5 at the end of the tank can discharge the recovered gas from the device. The connecting frame 8 can remove the oil filter tank 2 for easy cleaning and maintenance of the main tank 1 and the oil filter tank 2. It can also facilitate the replacement of the filter element 203. The device is supported by the support frame 6.

[0034] Specifically, a first fan 3 is provided at the front end of the oil filter tank 2. The first fan 3 is located at the axial position of the front end of the oil filter tank 2. The first fan 3 has an air intake fan protective cover 301 with a filter element.

[0035] By setting the first fan 3, the oil mist gas entering the oil filter tank 2 can be pressurized to a certain level, so that the gas enters the filtrate collection tank 205 side. At the same time, the suction fan protective cover 301 can protect the first fan 3, and the filter element set in the suction fan protective cover 301 can absorb impurities from the outside air.

[0036] Specifically, the bottom of the oil filter tank 2 is provided with filter holes 204, and a filtrate collection tank 205 is installed below the oil filter tank 2 via a slide rail that can be unloaded. The gap of the filtrate collection tank 205 is aligned with the filter holes 204.

[0037] By setting up a filtrate collection tank 205 and filter holes 204, when oil mist gas enters the oil filter tank 2, it will first come into contact with the inner wall of the oil filter tank 2, which may cause larger particles to directly adhere to the inner wall of the oil filter tank 2; these large particles can be recovered by entering the filtrate collection tank 205 through the filter holes 204 under the influence of gravity.

[0038] Specifically, a storage tank support 701 is welded to one side of the main tank body 1. A condensate storage tank 7 is mounted on the storage tank support 701. A condensate valve 702 is detachably connected to the condensate storage tank 7. The other end of the condensate valve 702 passes through the main tank body 1 and is connected to the condensate contact tank 102. A pressure gauge 703 is also mounted on the condensate valve 702.

[0039] By setting up a condensate storage tank 7, which can be filled with condensing gas such as liquid nitrogen, a continuous supply of condensing gas can be provided to the condensation contact tank 102 to ensure the condensation effect. At the same time, the condensate valve 702 can also release the gas in the condensation contact tank 102 in a timely manner through atmospheric pressure. The pressure gauge 703 can continuously monitor the gas pressure in the condensation contact tank 102.

[0040] Specifically, a row of condensation holes 104 is provided on the bottom inner side of the main tank 1; a condensation recovery box 105 is placed at the bottom of the condensation holes 104.

[0041] By setting condensation holes 104, the liquid after the oil mist gas is condensed can drip out from the main tank 1 in a timely manner through condensation holes 104, and be received by condensation recovery box 105. The condensation recovery box 105 is independent of the overall device and can be replaced anytime and anywhere, which facilitates the recycling work.

[0042] Specifically, the main tank 1 is provided with a second fan bracket 4 at its processing end. The second fan bracket 4 is rotatably mounted with a second fan shaft 401, and the second fan shaft 401 is provided with a detachable second fan 402.

[0043] By setting the second fan bracket 4, the second fan shaft 401 and the second fan 402 can be installed at the end of the main tank 1 to provide negative pressure, so that the oil mist gas in the main tank 1 can be discharged from the exhaust pipe 5 in a timely manner, thereby achieving an overall recycling and purification process.

[0044] Working principle: The device collects particles in the oil mist gas that cannot pass through the filter element 203 into the filtrate collection tank 205 through the filter hole 204 and the filtrate collection tank 205. At the same time, the filter element 203 can perform initial physical purification and recovery of the oil mist gas. When the oil mist enters the main tank 1, the condensing gas in the condensation contact tank 102 will condense the impurities of the oil mist onto the surface of 108 and the condensation contact tank 102. Then, under the influence of gravity, it flows into the condensation hole 104 and is collected and recovered through the condensation recovery box 105. The second fan 402 helps the condensed gas to be discharged from the exhaust pipe 5.
