Description

Technical Field

[0001] The utility model relates to the technical field of gas purification equipment, in particular to a gas purification equipment for an exhaust port of a hydrochloric acid tank. Background Art

[0002] Hydrochloric acid storage tank is a tank specially used to store hydrochloric acid, sulfuric acid and other highly corrosive substances. It can be made of plastic or fiberglass. Hydrochloric acid storage tanks made of plastic can be packaged and sold as small barrels of hydrochloric acid, while hydrochloric acid storage tanks made of fiberglass are generally produced to be able to be stored for a long time. The exhaust port of the hydrochloric acid tank is an interface for discharging the gas or steam generated inside the hydrochloric acid storage tank. These exhaust ports are designed and installed to ensure the safe operation of the hydrochloric acid storage tank and the stability of the internal pressure. The correct setting of the exhaust port helps prevent the internal pressure of the storage tank from being too high, thereby avoiding potential safety risks. The exhaust port can also be used to monitor the pressure changes inside the storage tank, and to perform necessary ventilation or exhaust operations when necessary to ensure the safe use of the storage tank. The gas discharged from the exhaust port of the hydrochloric acid tank will degrade in the atmosphere to form acid rain, which is harmful to the environment. If the gas is absorbed by the human body, it may cause serious harm to the human respiratory tract, skin, etc.

[0003] The gas purification equipment for the exhaust port of the hydrochloric acid tank is a device specially used to treat and purify the high-concentration acid mist volatilized from the exhaust port of the hydrochloric acid storage tank. This equipment usually absorbs the acid mist by water spraying to achieve the purification purpose and ensure that the discharged gas meets environmental protection standards.

[0004] However, water spraying is generally suitable for absorbing low-concentration hydrochloric acid gas, and only a single purification method is likely to cause incomplete gas purification, thereby causing harm to the environment. Therefore, it is particularly important to improve the existing hydrochloric acid tank exhaust port gas purification equipment and design a new type of hydrochloric acid tank exhaust port gas purification equipment to solve the above-mentioned technical defects and improve the practicability of the overall hydrochloric acid tank exhaust port gas purification equipment.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A gas purification device for the exhaust port of a hydrochloric acid tank comprises a recovery tank 1, wherein the internal thread of the recovery tank 1 is connected to an air inlet pipe 4, the internal end of the recovery tank 1 and away from the air inlet pipe 4 is threadedly connected to a first air supply pipe 41, the external end of the first air supply pipe 41 and away from the recovery tank 1 is threadedly connected to an alkali dissolving tank 2, the internal end of the alkali dissolving tank 2 and away from the first air supply pipe 41 is threadedly connected to a second air supply pipe 42, the external end of the second air supply pipe 42 and away from the alkali dissolving tank 2 is threadedly connected to a water dissolving tank 3, when the gas purification device for the exhaust port of the hydrochloric acid tank is put into use, the exhaust port of the hydrochloric acid tank is connected to the first air supply pipe 41, and the exhaust port of the hydrochloric acid tank is connected to the first air supply pipe 42. 41 is connected to the recovery tank 1, and the power is turned on. The gas from the exhaust port of the hydrochloric acid tank enters the recovery tank 1 through the first gas pipe 41 to be condensed and recovered, completing the initial purification. The remaining gas with a higher concentration enters the alkali solution tank 2 through the first gas pipe 41 to be absorbed by the alkali solution to complete the second purification. The remaining gas with a lower concentration enters the water solution tank 3 through the second gas pipe 42 to be dissolved and absorbed by water. Multiple purifications ensure the completeness of the purification. The recovery tank 1, the alkali solution tank 2, the water solution tank 3, the air inlet pipe 4, the first gas pipe 41 and the second gas pipe 42 are all threaded connections, which not only have good sealing properties but also are convenient for future disassembly, cleaning and maintenance.

[0026] Furthermore, a recovery cover 11 is threadedly connected to the top of the recovery tank 1, and two groups of opposite grooves 12 are opened on the top of the recovery cover 11. A plurality of semiconductor refrigeration sheets 5 are arranged inside the recovery tank 1 and at the bottom of the recovery cover 11. The semiconductor refrigeration sheet 5 has a cooling end and a heating end that are relatively arranged. When the semiconductor refrigeration sheet 5 is working, as long as current passes through, heat transfer will occur between its two ends, and the heat will be transferred from one end to the other end, thereby generating a temperature difference at both ends of the semiconductor refrigeration sheet 5 to form a cooling end and a heating end. When the gas purification equipment for the exhaust port of the hydrochloric acid tank is put into use, the exhaust port of the hydrochloric acid tank is connected to the recovery tank 1 through the first gas pipe 41, and the power is turned on. The end of the semiconductor refrigeration sheet 5 close to the groove 12 is the cooling end, and the end away from the groove 12 is the heating end, thereby reducing the temperature inside the recovery tank 1, thereby condensing and recovering part of the gas, thereby completing the preliminary purification. The groove 12 makes it convenient to unscrew the recovery cover 11, thereby facilitating the disassembly of the recovery tank 1, and facilitating future cleaning and maintenance.

[0027] Among them, the top of the alkali dissolving tank 2 is threadedly connected with an alkali dissolving cover 21, the internal thread of the alkali dissolving cover 21 is threadedly connected with a first nozzle 6, the inside of the first nozzle 6 and one end away from the alkali dissolving tank 2 is fixedly connected with a liquid inlet pipe 61, the outside of the alkali dissolving tank 2 and located at the bottom of the second gas pipe 42 is fixedly connected with a first liquid discharge pipe 22, when the gas purification equipment for the exhaust port of the hydrochloric acid tank is put into use, the gas with a relatively high concentration remaining after the initial purification enters the alkali dissolving tank 2 through the first gas pipe 41, the alkaline solution entering from the liquid inlet pipe 61 is sprayed into the interior of the alkali dissolving tank 2 by the first nozzle 6, thereby absorbing the gas with a relatively high concentration, thereby completing the secondary purification, and the liquid after the reaction is completed is discharged through the first liquid discharge pipe 22, the alkali dissolving tank 2, the alkali dissolving cover 21, the first gas pipe 41, the second gas pipe 42 and the first nozzle 6 are all threadedly connected, which not only has good sealing performance but also is convenient for future disassembly, cleaning and maintenance.

[0028] Secondly, a water-soluble cover 31 is threadedly connected to the top of the water-soluble tank 3, and a second nozzle 7 is threadedly connected to the inside of the water-soluble cover 31. A water inlet pipe 71 is fixedly connected to the inside of the second nozzle 7 and at one end away from the water-soluble tank 3. A second liquid discharge pipe 32 is fixedly connected to the outside of the water-soluble tank 3 and located at the bottom of the second gas pipe 42. When the gas purification equipment is used for the exhaust port of the hydrochloric acid tank, the gas with a lower remaining concentration after the secondary purification enters the water-soluble tank 3 through the second gas pipe 42, and the water entering from the water inlet pipe 71 is sprayed into the inside of the water-soluble tank 3 through the second nozzle 7, thereby absorbing the gas with a lower remaining concentration, thereby completing the third purification. The liquid after the reaction is completed is discharged through the second liquid discharge pipe 32. Multiple purifications ensure the completeness of the purification. The water-soluble tank 3, the water-soluble cover 31, the second nozzle 7 and the second gas pipe 42 are all threadedly connected, which not only has good sealing performance but also is convenient for future disassembly, cleaning and maintenance.

[0029] Furthermore, the interior of the recovery tank 1, the recovery cover 11, the alkali-soluble tank 2, the alkali-soluble cover 21, the water-soluble tank 3 and the water-soluble cover 31 are all provided with an anti-corrosion layer 8, and the anti-corrosion layer 8 is made of fiberglass. The fiberglass material is made of glass fiber and resin interwoven with each other. The fiber enhances the strength and toughness of the material, while the resin provides good corrosion resistance, so that the equipment has strong corrosion resistance, light weight, high strength, and extended service life.

[0030] Furthermore, a thermal insulation layer 81 is provided inside the recovery tank 1, the recovery cover 11, the alkali-soluble tank 2, the alkali-soluble cover 21, the water-soluble tank 3 and the water-soluble cover 31 and on the outside of the anti-corrosion layer 8. The thermal insulation layer 81 is made of glass wool material. Glass wool has a low thermal conductivity, which can effectively prevent the invasion of cold air and hot air from the outside, maintain the internal temperature stable, and has the advantages of good sound absorption and noise reduction performance, affordable price, good corrosion resistance, etc., which stabilizes the internal temperature of the equipment, thereby avoiding the influence of external temperature changes on the internal gas absorption, ensuring the stability of the purified gas and reducing costs.

[0031] Furthermore, an anti-collision layer 82 is provided inside the recovery tank 1, the recovery cover 11, the alkali-soluble tank 2, the alkali-soluble cover 21, the water-soluble tank 3 and the water-soluble cover 31 and at one end of the thermal insulation layer 81 away from the anti-corrosion layer 8. The anti-collision layer 82 is made of rubber material. The rubber material has good elasticity and strong wear resistance, which makes the equipment not easily damaged and extends its service life.

[0032] In this embodiment, the implementation scenario is specifically as follows: in actual use, when the hydrochloric acid tank exhaust port is put into use with a gas purification device, the hydrochloric acid tank exhaust port is connected to the recovery tank 1 through the first gas pipe 41, the power is turned on, the end of the semiconductor refrigeration plate 5 close to the groove 12 is the cooling end, and the end away from the groove 12 is the heating end, thereby reducing the temperature inside the recovery tank 1, thereby condensing and recovering part of the gas, thereby completing the initial purification. After the initial purification is completed, the gas with a relatively high concentration remaining enters the alkali dissolving tank 2 through the first gas pipe 41, and the alkaline solution entering from the liquid inlet pipe 61 is sprayed into the interior of the alkali dissolving tank 2 by the first nozzle 6, thereby absorbing the gas with a relatively high concentration, thereby completing the secondary purification. The liquid after the reaction is completed is discharged through the first drain pipe 22. After the secondary purification is completed, the gas with a relatively low concentration remaining enters the water dissolving tank 3 through the second gas pipe 42, and the water entering from the water inlet pipe 71 is sprayed into the interior of the water dissolving tank 3 through the second nozzle 7, thereby absorbing the gas with a relatively high concentration remaining. Low gas absorption, thereby completing three purifications, and the liquid after the reaction is completed is discharged through the second drain pipe 32. Multiple purifications ensure the completeness of the purification. The alkali-soluble tank 2, the water-soluble tank 3, the air inlet pipe 4, the first air supply pipe 41 and the second air supply pipe 42, the alkali-soluble cover 21, the first nozzle 6, the water-soluble cover 31 and the second nozzle 7 are all threaded connections, which not only have good sealing but also are convenient for future disassembly, cleaning and maintenance. The anti-corrosion layer 8 is made of fiberglass material, which makes the equipment have strong corrosion resistance, light weight, high strength, and extended service life. The thermal insulation layer 81 is made of glass wool material, which stabilizes the internal temperature of the equipment, thereby avoiding the influence of internal gas absorption due to changes in external temperature, ensuring the stability of the purified gas and reducing costs. The anti-collision layer 82 is made of rubber material, which makes the equipment not easily damaged and extends its service life. Compared with the existing gas purification equipment for the exhaust port of the hydrochloric acid tank, the utility model can improve the overall practicality of the gas purification equipment for the exhaust port of the hydrochloric acid tank through design.
