Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen discharge devices, in particular to a safe hydrogen discharge device for an electrolytic sodium hypochlorite generator. Background Art

[0002] An electrolytic sodium hypochlorite generator is a device that produces sodium hypochlorite solution by electrolyzing salt water. During the electrolysis process, in addition to sodium hypochlorite, by-products such as hydrogen are also produced. Since hydrogen is a flammable and explosive gas, if it is not discharged in time, it will accumulate in the equipment. When it reaches a certain concentration and conditions, it may cause serious safety accidents such as explosions. The safe hydrogen discharge device can discharge the generated hydrogen to an appropriate location in a timely and safe manner, reducing the hydrogen concentration in the equipment, ensuring the safe operation of the equipment, protecting the safety of personnel and the production environment, and preventing potential explosion hazards.

[0003] During the electrolysis process, the generated hydrogen may carry a small amount of electrolyte or sodium hypochlorite solution. However, the existing electrolytic sodium hypochlorite generator safety hydrogen discharge device is usually unable to remove the small amount of electrolyte or sodium hypochlorite solution contained in the hydrogen. If the hydrogen carries liquid, the droplets will form atomization during the discharge process, increasing the contact area between hydrogen and air, thereby increasing the risk of explosion.

Therefore, a safety hydrogen discharge device for the electrolytic sodium hypochlorite generator is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a safe hydrogen discharge device for an electrolytic sodium hypochlorite generator includes a base plate, three supporting legs are fixedly connected to the top of the base plate, a fixing ring is fixedly connected between the tops of the three supporting legs, the inner surface wall of the fixing ring is fixedly connected to a treatment tank, the outer surface wall of the treatment tank is fixedly connected to an air inlet pipe, the inner surface wall of the treatment tank is fixedly connected to a baffle, the inner surface wall of the treatment tank is fixedly connected to a filter screen, three umbrella plate separators are fixedly connected to the inner surface wall of the treatment tank, a wire mesh demister is fixedly connected to the inner surface wall of the treatment tank, a fixed bed adsorption plate is fixedly connected to the inner surface wall of the treatment tank, a liquid level gauge is provided on the outer surface wall of the treatment tank, and the bottom of the treatment tank is fixedly connected to a drain pipe.

[0010] Preferably, a one-way valve is provided on the inner surface wall of the delivery pipe.

[0011] Preferably, the output end of the delivery pipe is fixedly connected to a gas storage tank.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] In the utility model, through the interaction of the various components of the device, the electrolyte and sodium hypochlorite solution mixed in the hydrogen are efficiently removed, and the solid particles and tiny droplets in the hydrogen are deeply filtered, thereby significantly improving the purity and safety of the hydrogen.

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4 As shown, the utility model provides a safe hydrogen discharge device for an electrolytic sodium hypochlorite generator, comprising a base plate 1, three supporting legs 2 being fixedly connected to the top of the base plate 1, a fixing ring 3 being fixedly connected between the tops of the three supporting legs 2, an inner surface wall of the fixing ring 3 being fixedly connected to a treatment tank 4, an outer surface wall of the treatment tank 4 being fixedly connected to an air inlet pipe 5, an inner surface wall of the treatment tank 4 being fixedly connected to a baffle 6, an inner surface wall of the treatment tank 4 being fixedly connected to a filter screen 7, three umbrella-plate separators 8 being fixedly connected to the inner surface wall of the treatment tank 4, a wire mesh demister 9 being fixedly connected to the inner surface wall of the treatment tank 4, a fixed bed adsorption plate 10 being fixedly connected to the inner surface wall of the treatment tank 4, a liquid level gauge 11 being provided on the outer surface wall of the treatment tank 4, and a drain pipe 12 being fixedly connected to the bottom of the treatment tank 4.

[0024] The effect achieved by the entire embodiment 1 is that the electrolytic sodium hypochlorite generator generates hydrogen while producing sodium hypochlorite. In order to ensure the purity and safety of the hydrogen, a series of treatments are required. First, the hydrogen enters the treatment tank 4 through the air inlet pipe 5. Since the hydrogen may contain a trace amount of electrolyte or sodium hypochlorite solution, these liquids will first encounter the baffle 6 when entering the treatment tank 4. When the hydrogen carries these tiny droplets through the baffle 6, due to the large inertia of the droplets, they cannot change direction as quickly as the gas, so they will be intercepted by the baffle 6 and forced to fall. The liquid droplets mixed in the hydrogen will naturally settle to the bottom of the treatment tank 4, achieving preliminary liquid-gas separation. Subsequently, the hydrogen passes through the filter 7. The main function of this filter 7 is to further filter out solid impurities in the hydrogen to ensure the cleanliness of the hydrogen. Then, the hydrogen enters the three umbrella plate separators 8. Inside these separators, the hydrogen is forced to change its flow direction and dispersed into smaller bubbles. At the same time, its During the rising process, the collision and contact with the umbrella plate causes the tiny droplets that may remain in the hydrogen to form larger droplets. These droplets settle to the bottom of the treatment tank 4 again due to gravity, thereby further improving the purity of the hydrogen. Afterwards, the hydrogen passes through the wire mesh demister 9. The wire mesh demister 9 uses the multi-layer fine structure of the wire mesh to further capture and remove the remaining tiny droplets and droplets in the hydrogen through inertial collision and interception. Finally, the hydrogen enters the fixed bed adsorption plate 10, which is filled with molecular sieve particles. These particles have high selectivity and adsorption capacity. When the hydrogen passes through the fixed bed, the molecular sieve will adsorb residual impurities or water vapor, trace amounts of oxygen, nitrogen, etc. in the hydrogen, thereby achieving deep purification of the hydrogen. This process not only improves the purity of the hydrogen, but also ensures its safety and stability during use. In summary, through this series of processing steps, the hydrogen generated by the electrolytic sodium hypochlorite generator is effectively purified and purified, providing reliable protection for subsequent applications.

[0025] Example 2, as Figure 2-Figure 4 As shown, a drain valve 13 is provided on the inner surface wall of the drain pipe 12, an exhaust pipe 14 is fixedly connected to the top of the processing tank 4, the output end of the exhaust pipe 14 is fixedly connected to a hydrogen compressor 15, the output end of the hydrogen compressor 15 is fixedly connected to a delivery pipe 16, a one-way valve 17 is provided on the inner surface wall of the delivery pipe 16, and the output end of the delivery pipe 16 is fixedly connected to a gas storage tank 18.

[0026] The effect achieved by the entire embodiment 2 is that, through the hydrogen compressor 15, the strictly treated and purified hydrogen can be efficiently compressed to increase its volume energy density. After this process is completed, the output end of the hydrogen compressor 15 will stably transport the compressed hydrogen to the gas storage tank 18 for centralized storage. This facilitates the subsequent flexible distribution and supply of hydrogen according to demand, realizes the effective storage and reuse of hydrogen, and promotes the widespread application of hydrogen as a clean energy and the development of a circular economy.

[0027] Working principle: During the operation of the electrolytic sodium hypochlorite generator, the generated hydrogen is first introduced into the treatment tank 4 through the air inlet pipe 5. In view of the trace electrolyte or sodium hypochlorite solution that may be carried in the hydrogen, it is effectively intercepted by the baffle 6 the moment it enters the treatment tank 4. The baffle 6 uses the physical barrier effect to force the hydrogen flow to change its original path. In this process, the accompanying liquid naturally settles to the bottom of the treatment tank 4 due to gravity, realizing preliminary liquid-gas separation. Subsequently, the hydrogen that has undergone preliminary separation continues to move forward and passes through the precisely arranged filter 7. The filter 7 can effectively intercept the solid impurities remaining in the hydrogen to ensure further purification of the hydrogen. Immediately afterwards, the hydrogen enters the three umbrella plate separators 8. When passing through the three umbrella plate separators 8, the trace liquid still carried in the hydrogen forms larger droplets. These droplets quickly settle to the bottom of the treatment tank 4 due to gravity, realizing deeper liquid-gas separation. After further processing by the umbrella plate separator 8 Finally, the hydrogen enters the wire mesh demister 9. The wire mesh demister 9 uses its unique wire mesh structure to effectively remove the remaining trace droplets in the hydrogen through inertial collision and interception mechanism, further improving the purity of the hydrogen. Finally, the highly pure hydrogen enters the fixed bed adsorption plate 10. The interior of the adsorption plate is tightly filled with high-performance molecular sieve particles. These particles have extremely strong adsorption capacity for trace moisture, oxygen and other impurities in the hydrogen. In the process of hydrogen passing through the fixed bed adsorption plate 10, the molecular sieve particles are fully in contact with the hydrogen, and the remaining trace liquids and impurities therein are completely adsorbed, thereby ensuring that the hydrogen is thoroughly purified. Subsequently, the treated hydrogen is compressed by the hydrogen compressor 15. The hydrogen is further compressed to a specified pressure and stably and safely transported to the gas storage tank 18 through its output end for long-term storage, which greatly facilitates the subsequent application of hydrogen, such as as a fuel supply for fuel cells, raw materials for chemical production, etc.
