Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil waste gas treatment, in particular to a waste gas treatment device based on lubricating oil production. Background Art

[0002] Lubricating oil is a non-volatile oily lubricant that mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is mainly composed of base oil and additives. The main application occasions of lubricating oil include various types of automobiles, mechanical equipment, etc., to reduce friction and protect machinery and processed parts. Liquid or semi-solid lubricants mainly play the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. In the current lubricating oil production process, toxic substances will be produced, mainly including non-methane total hydrocarbons or ethylene glycol factors, which exist in the exhaust gas of the blending device and are generally treated using an exhaust gas treatment device.

[0003] The existing Chinese patent with announcement number CN212262879U discloses a waste gas treatment device for lubricating oil production, wherein a support base is fixedly installed on the lower surface of the first treatment tank, and a treatment component is arranged on the other side of the first treatment tank, and a liquid outlet pipe is connected to one side of the lower end of the first treatment tank, and one end of the liquid outlet pipe is fixedly connected to a water collecting tank.

[0004] Although the above scheme can absorb the odor and some smaller impurity particles contained in the exhaust gas and treat the exhaust gas multiple times, since the exhaust gas will first contact the filter element when it enters, the filter element will consume its service life faster. The exhaust gas treatment device sets the filter element at the bottom, which makes it difficult to replace. At the same time, the exhaust gas treatment device is equipped with two treatment tanks, which makes the overall movement inconvenient. Therefore, it does not meet the existing needs. In this regard, we propose an exhaust gas treatment device based on lubricating oil production. Utility Model Content

[0005] The utility model aims to provide an exhaust gas treatment device for lubricating oil production to solve the problem that the exhaust gas treatment device mentioned in the background technology is inconvenient to replace and move the filter element.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an exhaust gas treatment device for lubricating oil production, comprising a main body, a filter chamber is provided inside the main body, a first purification chamber is provided on one side of the filter chamber, a second purification chamber is provided below the filter chamber, and the second purification chamber is communicated with the first purification chamber;

[0007] It also includes a filter plate, which is arranged inside the filter cavity, and four filter plates are arranged at equal intervals, and an activated carbon filter screen is arranged inside each of the filter plates, one end of each of the filter plates extends to the outside of the filter cavity, and each of the filter plates is slidably matched with the filter cavity;

[0008] It also includes universal wheels with locks, which are installed at the four corners of the lower end of the main body.

[0009] Preferably, a cover plate is rotatably provided on one side of the upper end of the main body, a hand screw is threadedly connected to one side of the interior of the cover plate, and the hand screw is threadedly connected to the main body.

[0010] Preferably, a water pump is provided on the lower side of one side of the first purification chamber, a nozzle is installed on the upper side of one side inside the first purification chamber, and the water pump, the nozzle and the first purification chamber are connected through a connecting pipe.

[0011] Preferably, a plurality of biological purification columns distributed in a rectangular array are arranged on the upper side of the interior of the second purification chamber.

[0012] Preferably, two handles are provided on the upper side of one side of the main body.

[0013] Preferably, an air inlet pipe is provided on one side of the filter chamber, an air outlet pipe is provided on one side of the second purification chamber, an L-shaped pipe is provided inside the second purification chamber, and one end of the L-shaped pipe is connected to the filter chamber.

[0014] Preferably, a liquid inlet pipe is provided at a position between one side of the first purification chamber, and a liquid outlet pipe is provided below the gas outlet pipe and the liquid inlet pipe.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model has four filter plates arranged inside the filter chamber. When the waste gas after lubricating oil production passes into the filter chamber, it will be filtered by the activated carbon filter on the filter plate. The user can release the connection between the cover plate and the main body by turning the hand screw. At this time, the activated carbon filter can be cleaned or replaced by just pulling out the filter plate, thereby ensuring the filtering and purification effect. The filtering process can be carried out for a long time. The replacement process is convenient and fast, the operation is simple, and it is easy to use.

[0017] 2. The utility model has a first purification chamber on one side of the main body, and a second purification chamber on one side of the first purification chamber. After the exhaust gas is filtered and purified for the first time, it will enter the interior of the oxidant solution through the L-shaped tube. The oxidant solution can react with the organic matter in the exhaust gas to convert it into harmless carbon dioxide and water, effectively reducing the concentration of harmful substances in the exhaust gas. A biological purification column is arranged inside the second purification chamber. The biological purification column is usually composed of a column filled with biologically active materials, and the core part is a microbial flora. When the exhaust gas passes through the biological purification column, the organic matter therein is adsorbed by the biologically active material and degraded by the microorganisms on the biofilm. The microorganisms use these organic matter as energy and nutrient sources and convert them into harmless substances, such as carbon dioxide and water, through metabolism, so that the exhaust gas produced by lubricating oil can be fully purified, and the exhaust gas treatment is more thorough.

[0018] 3. The utility model has locked universal wheels installed at the four corners of the lower end of the main body. After the locking mechanism of the locked universal wheels is opened, the locked universal wheels can roll, thereby driving the main body to move conveniently. The user can increase the fulcrum through the handle to provide external force for the movement of the main body, thereby conveniently moving the main body to a desired position, thereby increasing portability.
