Description

Technical Field

[0001] This utility model belongs to the field of screw compressor technology, specifically relating to an oil collector used in the mechanical seal of a process screw compressor. Background Technology

[0002] Mechanical seals in process screw compressors are key components that prevent leakage of process gases and lubricating oil within the compressor cavity. Under normal operating conditions, mechanical seals will inevitably leak to some extent. As the equipment operates for longer periods, the sealing effect of the mechanical seal gradually deteriorates, and the leakage will continue to increase. In addition to lubricating oil, small amounts of toxic and harmful process gases are usually leaked out.

[0003] In the industry, the common practice for dealing with mechanical seal leaks is to place a regular container under the leak to collect the dripping lubricating oil. After the gas leaks, it is directly released into the surrounding atmosphere, which also carries away some oil mist. Process gases are generally flammable, explosive, or even toxic. This practice causes serious environmental pollution and also poses certain dangers. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an oil collector for use in the mechanical seal of a process screw compressor, which effectively solves the environmental pollution and human health risks caused by direct gas emission in the prior art.

[0005] The technical solution of this utility model is: an oil collector for mechanical seals of process screw compressors, including an oil collector, a drain inlet, an activated carbon canister and an exhaust port. The oil collector is provided with a partition, which divides the interior of the oil collector into an oil storage chamber and an air storage chamber.

[0006] The drain inlet is located on the side of the oil collector and is used to connect to the drain port of the mechanical seal to introduce the leaked oil-gas mixture.

[0007] The activated carbon canister is installed inside the oil collector. The bottom of the activated carbon canister has a bottom hole that communicates with the oil storage chamber. The side of the activated carbon canister has a side hole that communicates with the gas storage chamber. The activated carbon canister is filled with activated carbon material for adsorbing toxic or odorous gases.

[0008] The exhaust port is located at the top of the oil collector and connected to the gas storage chamber, and is used to discharge the gas purified by the activated carbon canister.

[0009] Preferably, a level gauge is installed on the side of the oil collector, and the level gauge is connected to the oil storage chamber to display the oil level in the oil collector.

[0010] Preferably, the level gauge is provided with a low level indicator line, a middle level indicator line and a high level indicator line to display different states of the oil level in the oil collector so as to discharge the lubricating oil in a timely manner.

[0011] Preferably, a ball valve is fixedly connected to the bottom of the side of the oil collector, and the ball valve is connected to the bottom of the oil storage chamber for discharging the collected lubricating oil.

[0012] Preferably, a fixing block is also fixedly connected to the oil collector for mounting the oil collector on the screw compressor.

[0013] Preferably, the partition has a through hole in the middle, and the activated carbon canister is inserted into the through hole.

[0014] Preferably, an outer ring is fixedly fitted on the outer wall of the activated carbon canister, and the bottom of the outer ring abuts against the top of the partition.

[0015] Preferably, the top of the oil collector is equipped with a cover plate, and the vent is located on the cover plate.

[0016] Preferably, a handle is fixedly connected to the top of the cover plate.

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0018] 1. In this application, the oil-gas mixture leaking from the mechanical seal enters the oil collector through the drain inlet. After the oil-gas mixture comes into contact with the outer wall of the activated carbon canister, the oil mist will condense into oil droplets under the action of impact force or centrifugal force and settle into the oil storage chamber at the bottom of the oil collector. Meanwhile, the gas enters the activated carbon canister through the bottom hole and is adsorbed by the activated carbon. The remaining gas enters the gas storage chamber through the side hole and is then discharged directionally through the exhaust port. This design effectively solves the environmental pollution and human health risks caused by the direct emission of gas in the prior art.

[0019] 2. In this application, the oil level can be displayed intuitively by the level gauge. When the oil level reaches the preset value, the operator can discharge the collected lubricating oil through the ball valve, thus avoiding secondary leakage caused by the overflow of the oil collector.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture.

[0027] Please see Figure 1-2 An oil collector for use in the mechanical seal of a process screw compressor includes an oil collector 1, a drain inlet 2, an activated carbon canister 3, and an exhaust port 4. The oil collector 1 is provided with a partition 11, which divides the interior of the oil collector 1 into an oil storage chamber 12 and an air storage chamber 13.

[0028] The drain inlet 2 is located on the side of the oil collector 1 and is used to connect to the drain port of the mechanical seal to introduce the leaked oil-gas mixture.

[0029] The activated carbon canister 3 is installed inside the oil collector 1. The bottom of the activated carbon canister 3 is provided with a bottom hole 31, which is connected to the oil storage chamber 12. The side of the activated carbon canister 3 is provided with a side hole 32, which is connected to the gas storage chamber 13. The activated carbon canister 3 is filled with activated carbon material for adsorbing toxic or odorous gases.

[0030] Exhaust port 4 is located at the top of oil collector 1 and connected to gas storage chamber 13, used to discharge gas purified by activated carbon canister 3. Oil-gas mixture leaking from the mechanical seal enters oil collector 1 through drain inlet 2. After the oil-gas mixture hits the outer wall of activated carbon canister 3, the oil mist condenses into oil droplets under impact or centrifugal force and settles into oil storage chamber 12 at the bottom of oil collector 1. Gas enters activated carbon canister 3 through bottom hole 31 and is adsorbed by activated carbon. The remaining gas enters gas storage chamber 13 through side hole 32 and is then discharged directionally through exhaust port 4. This design effectively solves the environmental pollution and human health risks caused by direct gas emission in existing technologies.

[0031] Under normal leakage conditions, only lubricating oil leaks. The lubricating oil drips into the oil storage chamber 12 of the oil collector 1, and the gas partially dissolved in the lubricant gradually evaporates and is discharged through the activated carbon canister 3 and the gas storage chamber 13 and then through the exhaust port 4.

[0032] In the event of a severe leak, the leaked lubricating oil and gas have a certain pressure, while the oil collector 1 is at normal pressure. Under the action of the pressure difference, a portion of the oil-gas mixture will be sprayed onto the outer wall of the activated carbon canister 3, resulting in a relatively large impact force. At the same time, a portion of the oil-gas mixture will continue to move along the smooth outer wall of the activated carbon canister 3, thus forming a certain centrifugal force.

[0033] This application can separate and collect oil and gas leaking from mechanical seals, avoiding direct emissions into the environment.

[0034] A level gauge 5 is installed on the side of the oil collector 1, and the level gauge 5 is connected to the oil storage chamber 12 to display the oil level in the oil collector 1. The level gauge 5 is equipped with a low-level indicator line 51, a medium-level indicator line 52, and a high-level indicator line 53 to display different states of the oil level in the oil collector 1, so as to drain the lubricating oil in a timely manner. A ball valve 6 is fixedly connected to the bottom of the side of the oil collector 1, and the ball valve 6 communicates with the bottom of the oil storage chamber 12 for draining the collected lubricating oil. The oil level can be visually displayed through the level gauge 5. When the oil level reaches the preset value, the operator can drain the collected lubricating oil through the ball valve 6 to avoid secondary leakage caused by the oil collector overflowing.

[0035] The oil collector 1 is also fixedly connected to a fixing block 7, which makes it easy to install the oil collector 1 on the bottom skid of the screw compressor.

[0036] The partition 11 has a through hole in the middle, into which the activated carbon canister 3 is inserted. An outer ring is fixedly fitted on the outer wall of the activated carbon canister 3, with the bottom of the outer ring abutting against the top of the partition 11. The activated carbon canister 3 is detachably installed on the partition 11, facilitating the replacement of the activated carbon material inside the activated carbon canister 3.

[0037] The top of the oil collector 1 is equipped with a cover plate 9, and the exhaust port 4 is located on the cover plate 9. The purified gas is discharged through the exhaust port 4 and then discharged to the designated discharge area through a thin pipe.

[0038] A handle 8 is fixedly connected to the top of the cover plate 9, which facilitates the lifting and movement of the oil collector 1.

[0039] Working principle: The drain port of the mechanical seal of the process screw compressor is connected to the drain inlet 2 of the oil collector 1 through a thin tube, so that the leaked oil-gas mixture is introduced into the oil collector 1.

[0040] After the oil-gas mixture enters the oil collector 1, it first impacts the outer wall of the activated carbon canister 3. Under the action of impact force or centrifugal force, the oil mist condenses into oil droplets and settles into the oil storage chamber 12 at the bottom of the oil collector 1, thus achieving preliminary separation of oil and liquid.

[0041] The gas enters the activated carbon canister 3 through the bottom hole 31 at the bottom of the activated carbon canister 3. The toxic or odorous gases (such as H2S) contained therein are adsorbed and purified by the activated carbon. The remaining gas flows into the gas storage chamber 13 through the side hole 32 on the activated carbon canister 3, and is finally discharged to the designated area through the exhaust port 4 at the top to avoid direct pollution of the environment.

[0042] A level gauge 5 is installed on the side of the oil storage chamber 12 of the oil collector 1. The oil level can be observed in real time through the level gauge 5, which is convenient for daily monitoring of mechanical seal leakage. When the oil level rises to the preset height, the bottom ball valve 6 can be opened to discharge the lubricating oil and prevent overflow. This design realizes the collection of leakage materials throughout the entire process through oil-gas separation, gas purification and level control, which not only reduces the risk of environmental pollution, but also improves the safety of equipment operation.
