Description

Technical Field

[0001] This utility model relates to the technical field of gas separation and purification devices, and more specifically, to a high-efficiency filter for gas separation and purification devices. Background Technology

[0002] Currently, when performing gas separation and collection operations, due to the presence of other impurities in the gas, it is usually necessary to pass the gas into a corresponding gas separation and purification device for purification. Gas separation and purification devices are key equipment in industrial production, laboratory research, and the medical field. Their core function is to efficiently separate and purify different components in a mixed gas to meet various application requirements. High-efficiency filters, as an important component of gas separation and purification devices, are of great significance for improving gas purity and ensuring stable system operation.

[0003] There are many types of gas separation and purification filters on the market, but most filters can only perform a single separation operation on the gas. This single separation affects the purification effect, and they cannot perform moisture removal on the treated gas, which also affects the purification effect and causes inconvenience to users. Therefore, we propose a high-efficiency filter for gas separation and purification devices. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a high-efficiency filter for a gas separation and purification device, including a first separation cylinder 1, a second separation cylinder 13 disposed on one side of the first separation cylinder 1, and a moisture-absorbing cylinder 16 disposed on one side of the second separation cylinder 13. A molecular sieve 161 is disposed inside the moisture-absorbing cylinder 16, and the molecular sieve 161 is used for moisture absorption to achieve the effect of drying the gas.

[0028] Specifically, an air inlet pipe 10 is fixedly installed on the body of the first separation cylinder 1. The top of the first separation cylinder 1 is connected to the second separation cylinder 13 through an air outlet pipe 12. The top of the second separation cylinder 13 is connected to the moisture absorption cylinder 16 through a conveying pipe 14. An external delivery pipe 162 is fixedly installed on the top of the moisture absorption cylinder 16. A conveying pump 3 is provided on one side of the first separation cylinder 1. A water outlet pipe 31 is fixedly installed at the water outlet end of the conveying pump 3. Two symmetrical vertical pipes 32 are fixedly installed on the water outlet pipe 31. Two symmetrical horizontal pipes 33 are fixedly installed on the vertical pipes 32. Multiple equally spaced nozzles 34 are fixedly installed at the bottom of the horizontal pipes 33. The nozzles 34 are located in the corresponding first separation cylinder 1 and second separation cylinder 13 to realize the spraying of liquid medicine to treat the gas, remove impurities, and achieve the effect of purification.

[0029] In this embodiment, an air inlet hood 11 is fixedly installed at the air outlet end of the air inlet pipe 10, and the air inlet hood 11 is located near the bottom of the first separation cylinder 1; an air outlet hood 121 is fixedly installed at the air outlet end of the air outlet pipe 12, and the air outlet hood 121 is located near the bottom of the second separation cylinder 13; a uniform distribution hood 141 is fixedly installed at the air outlet end of the conveying pipe 14, and the uniform distribution hood 141 is located near the bottom of the moisture absorption cylinder 16, so that the gas flows from bottom to top for processing.

[0030] Specifically, a protruding post 15 is fixedly installed at the top of the conveying pipe 14 inside the moisture absorption cylinder 16. A protective cover 151 is fixedly installed at the top of the protruding post 15. An adding pipe 17 is fixedly installed on the top surface of the moisture absorption cylinder 16. A threaded cap 171 is threadedly connected to the adding pipe 17. The protective cover 151 is conical and located directly below the adding pipe 17, which facilitates the addition of molecular sieve 161 into the moisture absorption cylinder 16 at the adding pipe 17. In addition, the protective cover 151 can provide anti-collision protection for molecular sieve 161 falling from above, preventing the molecular sieve 161 from directly hitting the conveying pipe 14 and damaging it.

[0031] Furthermore, a conical cover 2 is fixedly installed at the bottom of the first separation cylinder 1, the second separation cylinder 13, and the moisture absorption cylinder 16. A drain pipe 20 is fixedly installed at the bottom end of the conical cover 2, and a valve 21 is fixedly installed on the drain pipe 20 to facilitate the drain operation.

[0032] In addition, a suction pipe 30 is fixedly installed at the water inlet end of the delivery pump 3, and the end of the suction pipe 30 is connected to the external medicine storage tank to enable normal suction of medicine.

[0033] It is worth noting that filter screens 4 are fixedly installed on the inner walls of both the first separation cylinder 1 and the second separation cylinder 13. The filter screens 4 are located between the corresponding upper and lower horizontal pipes 33. After the filter screens 4 are wetted by the medicine, as the gas passes through the filter screens 4, the gas can react more fully with the medicine on the filter screens 4, thereby improving the gas treatment effect.

[0034] When using the high-efficiency filter of the gas separation and purification device of this utility model, the inlet pipe 10 is connected to the external gas delivery pipe. After the gas enters through the inlet pipe 10, the delivery pump 3 is connected to the external power supply and made to work. The delivery pump 3 works to deliver the liquid medicine to the nozzle 34 and spray it out. The sprayed liquid medicine can react with the impurity gas in the gas to remove the impurity gas. After the gas is purified twice in the first separation cylinder 1 and the second separation cylinder 13, the purified gas enters the moisture absorption cylinder 16 through the delivery pipe 14. The gas continues to be dried through the molecular sieve 161 and then discharged through the external delivery pipe 162.

[0035] When there is a large amount of waste liquid accumulated in the first separation cylinder 1 and the second separation cylinder 13, the valve 21 below can be opened to perform a sewage discharge operation.

[0036] In addition, when molecular sieve 161 fails, open valve 21 at the bottom to discharge molecular sieve 161, and then add new molecular sieve 161 through addition pipe 17 to continue the drying operation.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
