Description

Technical Field

[0001] The utility model relates to the technical field of methanol filters, in particular to a methanol filter for low-temperature methanol production. Background Art

[0002] In the field of coal chemical industry, the low-temperature methanol washing process is one of the important technologies for gas purification and is widely used in the production process of chemical products such as synthetic ammonia and synthetic methanol. This process uses cold methanol as the absorption solvent and utilizes the high solubility of methanol in acidic gases (such as CO2, H2S, COS, etc.) at low temperatures to effectively remove acidic gases from the raw gas. The methanol in the low-temperature methanol washing process is recycled, but during the circulation process, impurities such as dust and carbonyl iron in the raw gas will adhere to the methanol, affecting the cleanliness of the methanol and the normal operation of the system. Therefore, it is necessary to set up a filter in the methanol circulation system, but the existing device has certain defects when filtering methanol.

[0003] For example, in a Chinese patent with the publication number "CN 218221447 U", a methanol filter for low-temperature methanol production is disclosed. When the device is used, the methanol is initially filtered through a filter plate. Therefore, impurities in the methanol will continue to accumulate on the feed side of the filter plate. As the use time increases, the filter plate will gradually become clogged. In order to allow the device to continuously filter methanol, the filter plate can be taken out of the transparent connecting tube through a semicircular sealing cover to clean it. Therefore, the device needs to be disassembled by personnel for cleaning, which makes it difficult to clean the device and has low cleaning efficiency. Utility Model Content

[0004] The utility model provides a methanol filter for low-temperature methanol production, so as to solve the problem that the existing methanol filtering device needs to be disassembled and cleaned by personnel, and the cleaning is difficult and inefficient.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a methanol filter for low-temperature methanol production, comprising a methanol filter body, on which a feed piece for inputting methanol to be filtered and a discharge piece for discharging filtered methanol are installed, and an infusion channel for conveying methanol to be filtered along a preset path is formed inside the feed piece, a filter plate is arranged inside the infusion channel, and a cleaning plate is also arranged inside the infusion channel, the cleaning plate is located on the feed side of the filter plate, a driving part is arranged on the feed piece, the output end of the driving part extends to the inside of the infusion channel and is connected to the filter plate, and the cleaning plate is driven to rotate relative to the filter plate by the driving part, so that the cleaning plate scrapes the feed side of the filter plate.

[0006] Preferably, the feed member includes a feed pipe, the discharge end of the feed pipe is fixedly connected to the feed end of the methanol filter body, and one side of the feed pipe is fixedly connected to a side pipe for inputting methanol, and the filter plate is fixedly connected to the inside of the feed pipe, and the filter plate is located between the side pipe and the methanol filter body.

[0007] Preferably, the driving part comprises a motor, the motor is fixedly connected to the feed pipe, and the output end of the motor is connected to an output shaft, and the output end of the output shaft is fixedly connected to the cleaning plate.

[0008] Preferably, the bottom of the feed pipe is open to form a bottom hole for discharging impurities, the side tube is located above the bottom hole, the filter plate is located above the bottom hole, and a detachable sealing cover is screwed on the bottom of the bottom hole.

[0009] Preferably, a connector is fixedly connected to the top of the sealing cover, a detachable collector is screwed to the top of the connector, and the top of the collector is open to form a collection chamber for collecting impurities.

[0010] Preferably, the collector comprises a collecting shell, a conical cover is fixedly connected to the interior of the collecting shell, the bottom diameter of the conical cover is smaller than the top diameter, and the bottom of the conical cover is open to form a through hole.

[0011] Preferably, a handle is fixedly connected to the bottom of the sealing cover.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] (1) A driving part is provided to drive the cleaning plate to rotate. When the filter plate filters methanol, the cleaning plate continuously scrapes the feed side of the filter plate, thereby continuously cleaning the feed side of the filter plate, so that the filter plate can continue to filter methanol normally. There is no need for personnel to disassemble the device for cleaning, which reduces the cleaning difficulty of the device and improves the cleaning efficiency of the device;

[0014] (2) On the basis of the above beneficial effects, when the cleaning plate cleans the filter plate and produces impurities, the impurities dropped on the filter plate are collected by the collector. After the device has been used for a certain period of time, the collector can be removed from the feed pipe by simply removing the sealing cover, thereby removing the impurities in the collector at one time, without the need to frequently clean the impurities, further reducing the cleaning difficulty of the device;

[0015] (3) On the basis of the above beneficial effects, when the collector collects impurities, the inverted conical cover cooperates to allow the impurities to pass through the through holes and enter the bottom of the collection shell, thereby preventing the impurities from flowing back under the flow of methanol, thereby improving the impurity collection efficiency and further reducing the difficulty of cleaning the device.

[0026] Through the above technical scheme, when personnel need to filter methanol, the methanol to be filtered is added to the feed piece 3, and the methanol is guided through the infusion channel on the feed piece 3 to make the methanol flow along the infusion channel. When the methanol flows in the infusion channel, the methanol is preliminarily filtered by the filter plate 39, so that the impurities in the methanol are retained on the feed side of the filter plate 39. The methanol after preliminary filtration is transported to the methanol filter body 2 for further filtration, and the completely filtered methanol is discharged through the discharge piece 1. The driving part works, and then the driving part drives the cleaning plate 37 to rotate, so that the cleaning plate 37 scrapes the feed side of the filter plate 39, and then cleans the impurities attached to the feed side of the filter plate 39, so that the filter plate 39 can continuously filter methanol.

[0027] Specifically, in one embodiment, regarding the above-mentioned feed member 3:

[0028] like Figure 1-Figure 5 As shown, the feed member 3 includes a feed pipe 31, the discharge end of the feed pipe 31 is fixedly connected to the feed end of the methanol filter body 2, and one side of the feed pipe 31 is fixedly connected to a side pipe 33 for inputting methanol, and a filter plate 39 is fixedly connected to the inside of the feed pipe 31, and the filter plate 39 is located between the side pipe 33 and the methanol filter body 2.

[0029] In this embodiment, methanol to be filtered is added to the side tube 33, and the methanol is guided by the side tube 33 so that the methanol flows along the side tube 33, and the methanol is transported to the inside of the feed pipe 31 through the side tube 33, and the methanol is guided by the feed pipe 31. When the methanol passes through the filter plate 39, the methanol is preliminarily filtered by the filter plate 39, so that impurities in the methanol are retained on the feed side of the filter plate 39, and the methanol after the preliminary filtration is transported to the methanol filter body 2 for further filtration, and the completely filtered methanol is discharged through the discharge piece 1, and the driving part works, so that the driving part drives the cleaning plate 37 to rotate, so that the cleaning plate 37 scrapes the feed side of the filter plate 39, and then cleans the impurities attached to the feed side of the filter plate 39, so that the filter plate 39 can continuously filter methanol.

[0030] In addition, in the present utility model, regarding the above-mentioned driving part:

[0032] In this embodiment, when the cleaning plate 37 needs to be driven to rotate, the motor 32 is operated to drive the cleaning plate 37 to rotate, and the cleaning plate 37 scrapes the filter plate 39, thereby cleaning the filter plate 39.

[0033] After the cleaning plate 37 cleans the filter plate 39, in order to facilitate the discharge of impurities, such as Figure 3-Figure 5 As shown, the bottom of the feed pipe 31 is open to form a bottom hole for discharging impurities, the side pipe 33 is located above the bottom hole, the filter plate 39 is located above the bottom hole, and a detachable sealing cover 35 is screwed and connected to the bottom of the bottom hole;

[0034] A handle 34 is fixedly connected to the bottom of the sealing cover 35 .

[0035] In this embodiment, the filter plate 39 is cleaned by the cleaning plate 37 to remove impurities attached to the filter plate 39. If personnel need to clean the impurities, they stop adding methanol, rotate the sealing cover 35, separate the sealing cover 35 from the feed pipe 31, and the impurities can be discharged through the bottom hole at the bottom of the feed pipe 31.

If personnel need to clean the impurities, stop adding methanol, rotate the sealing cover 35 to separate the sealing cover 35 from the feed pipe 31, take out the collector 310, and clean the impurities in the collector 310, making it easier to clean the impurities.

[0038] In addition, in the present invention, regarding the collector 310: Figure 3-Figure 5 As shown, the collector 310 includes a collecting shell 3101 , and a conical cover 3102 is fixedly connected to the interior of the collecting shell 3101 .

When personnel need to clean the impurities, they can rotate the sealing cover 35 to separate the sealing cover 35 from the feed pipe 31, take out the collector 310, and clean the impurities in the collector 310, making it easier to clean the impurities.
