[0027] To address the inconvenience of cleaning scale after dissolution in a steam-type water-bath vaporizer, the present invention designs an overflow water recovery device for a liquid oxygen and liquid nitrogen water-bath vaporizer. The device comprises a vaporizer body, a first overflow pipe, and a second overflow pipe. Specifically, a large amount of scale has accumulated in the vaporizer body due to prolonged use. A worker first stops the vaporizer body and then adds an appropriate amount of chemical to dissolve the scale. The chemical gradually dissolves the scale into dust, which floats within the vaporizer body. After a period of time, the dust settles at the bottom of the vaporizer body. Next, a liquid is injected into the vaporizer body. As the liquid is injected, the pressure within the vaporizer body gradually increases. Under the influence of this pressure, the liquid enters the second overflow pipe through a second water inlet near the bottom of the first cavity. The liquid entering the second water inlet carries the dust settled at the bottom of the first cavity into a second passage formed between the second overflow pipe and the first overflow pipe. Subsequently, the liquid carrying the dust continues to enter the first passage inside the first overflow pipe and is finally discharged from the gasifier body, completing the cleaning and discharge process of the scale dust.

[0028] The benefits of this method include effectively solving the problem of scale removal difficulties within the vaporizer body, eliminating the need for complex disassembly and deep cleaning, saving time and labor costs. Rapid scale removal reduces downtime for cleaning, improving equipment efficiency and production continuity. Timely scale removal helps maintain the optimal working condition of the vaporizer, ensuring consistent gasification and product quality. Regular scale removal reduces corrosion and damage to the vaporizer's internal structure, extending its service life. This avoids the high costs associated with frequent vaporizer replacement or extensive repairs, reducing equipment maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0040] Reference Figures 1 to 5, which is the first embodiment of the present utility model, proposes an overflow water recovery device for a liquid oxygen and liquid nitrogen water bath vaporizer, including a vaporizer body 1, the vaporizer body 1 having a first cavity 101 therein; a first overflow pipe 2 is arranged in the first cavity 101, the first overflow pipe 2 has a first passage 201 therein, the first overflow pipe 2 has a first water inlet 202 and a first water outlet 203 at both ends, and the first water outlet 203 extends out of the first cavity 101 from the bottom of the vaporizer body 1; a second overflow pipe 3 has a cover 301 at one end and a second water inlet 302 at the other end, the second overflow pipe 3 is sleeved on the outside of the first overflow pipe 2, the first water inlet 202 is arranged in the second overflow pipe 3, the second water inlet 302 is close to the bottom of the first cavity 101, a second passage 303 is provided between the second overflow pipe 3 and the first overflow pipe 2, and the second passage 303 is connected to the first passage 201.

[0041] In this embodiment, to address the difficulty in cleaning scale after dissolution in a steam-type water bath vaporizer, a liquid oxygen and liquid nitrogen water bath vaporizer overflow water recovery device is designed. The device includes a vaporizer body 1, a first overflow pipe 2, and a second overflow pipe 3. Specifically, a large amount of scale has accumulated in the vaporizer body 1 due to long-term use. A worker first stops the operation of the vaporizer body 1 and then adds an appropriate amount of chemical agent to the vaporizer body 1 to dissolve the scale. Under the action of the chemical agent, the scale gradually dissolves into dust and floats in the vaporizer body 1. After a period of time, the dust settles at the bottom of the vaporizer body 1. Next, the worker injects liquid into the vaporizer body 1. As the liquid is injected, the pressure in the vaporizer body 1 gradually increases. Under the action of pressure, the liquid enters the second overflow pipe 3 from the second water inlet 302 near the bottom of the first cavity 101. The liquid entering the second water inlet 302 carries the dust settled at the bottom of the first cavity 101 and flows into the second passage 303 formed between the second overflow pipe 3 and the first overflow pipe 2. The liquid carrying the dust then continues to flow into the first passage 201 inside the first overflow pipe 2 and eventually exits the vaporizer body 1, completing the cleaning and discharge process of scale and dust.

[0042] The advantage is that it effectively solves the problem of difficult scale cleaning inside the vaporizer body 1, eliminating the need for complex disassembly and deep cleaning of the vaporizer body 1, saving time and labor costs. It can quickly clean scale dust, reducing the downtime of the vaporizer due to cleaning, and improving the operating efficiency and production continuity of the equipment. Timely scale cleaning helps maintain the good working condition of the vaporizer, ensuring the stability of the gasification effect and product quality. Regular scale cleaning can reduce scale corrosion and damage to the internal structure of the vaporizer, extending the service life of the vaporizer. It avoids the high costs of frequent replacement of vaporizers or large-scale repairs, reducing the company's equipment maintenance costs.

[0043] Furthermore, the axes of the gasifier body 1 , the first overflow pipe 2 and the second overflow pipe 3 coincide with each other.

[0044] Furthermore, it also includes connecting rods 4, which are multiple in number. The two ends of the connecting rods 4 are respectively arranged on the first overflow pipe 2 and the second overflow pipe 3, and the multiple connecting rods 4 are evenly arranged in the second passage 303 along the axis of the first overflow pipe 2.

[0045] In this embodiment, the axes of the vaporizer body 1, the first overflow pipe 2, and the second overflow pipe 3 coincide, ensuring the structural stability of the entire device and smooth water flow. In the second passage 303, a number of connecting rods 4 are evenly distributed along the axis of the first overflow pipe 2.

[0046] The advantage lies in the design of the coincident axes of the vaporizer body 1, the first overflow pipe 2, and the second overflow pipe 3, which makes the overall structure of the device more stable, reduces the stress and vibration caused by component misalignment, and extends the service life of the equipment. A number of evenly distributed connecting rods 4 can precisely fix the relative positions of the first overflow pipe 2 and the second overflow pipe 3, ensuring that they will not shift or deform under the influence of water flow and pressure, thereby ensuring the stability and reliability of overflow water recovery. The evenly distributed connecting rods 4 ensure that the first overflow pipe 2 and the second overflow pipe 3 are subjected to more uniform forces when subjected to internal pressure and external impact, reducing the risk of localized damage.

[0047] Furthermore, it also includes a water collection tank 5, which is connected to the first passage 201 and is used to collect overflow water; a pump body 6 is arranged at the water outlet of the water collection tank 5; a circulating water tank 7 is connected to the pump body 6, and the pump body 6 is used to transport the overflow water in the water collection tank 5 to the circulating water tank 7.

[0048] In this embodiment, when scale needs to be cleaned from the vaporizer body 1, overflow water laden with scale dust is discharged through the first overflow pipe 2 and the second overflow pipe 3 and enters the first passage 201. The overflow water flows along the first passage 201 into the water collection tank 5. After the water collection tank 5 collects a certain amount of overflow water, the pump 6 located at the water outlet of the water collection tank 5 is activated. Pump 6 begins to operate, pumping the overflow water from the water collection tank 5 and transferring it to the circulating water tank 7.

[0049] The advantage is that the coordination of the water collection tank 5, pump body 6, and circulating water tank 7 enables the recovery and reuse of overflow water, conserving water resources and reducing production costs. This reduces water waste and the demand for external fresh water resources, contributing to environmental protection and sustainable development. It also improves the operating system of the entire liquid oxygen and liquid nitrogen water bath vaporizer, enhancing overall efficiency and cost-effectiveness.

[0050] Furthermore, a filtering device 8 is included, the two ends of which are respectively connected to the first water outlet 203 and the water inlet of the water collecting tank 5, and are used to filter scale residues in the gasifier body 1 flowing out of the first passage 201.

[0051] In this embodiment, after scale removal is complete within vaporizer body 1, overflow water containing scale residue flows out of first water outlet 203 of first overflow pipe 2. On its way to water collection tank 5, it first passes through filter device 8, effectively intercepting scale residue. Subsequently, water in water collection tank 5 is pumped to circulating water tank 7 by pump body 6, achieving water recycling.

[0052] The advantage is that the filter device 8 can effectively remove scale residues flowing out of the vaporizer body 1, improving the quality of the recovered water and making it more suitable for recycling. It also prevents scale residues from entering the water collection tank 5, pump body 6, and circulating water tank 7, reducing wear and clogging of these devices and extending their service life.

[0053] Furthermore, the vaporizer body 1 includes an outer shell 102, and the interior of the outer shell 102 is a first cavity 101; the coil 103 is arranged in the first cavity 101 for liquid oxygen heat exchange; the steam pipeline 104 has an air inlet 1041 and an air outlet 1042, the air outlet 1042 is located in the first cavity 101, and the air inlet 1041 extends out of the first passage 201 and is located outside the first cavity 101.

[0054] Furthermore, the steam pipeline 104 is arranged in the first passage 201, the air inlet 1041 passes through the first overflow pipe 2 outside the first cavity 101, and the number of air outlets 1042 is several and evenly distributed along the circumference of the axis of the second overflow pipe 3, and the air outlets 1042 pass through the first overflow pipe 2 in the first cavity 101.

[0055] In this embodiment, the outer shell 102 of the vaporizer body 1 forms an internal first cavity 101. A coil 103 disposed within the first cavity 101 is used for heat exchange with liquid oxygen. An air inlet 1041 of the steam line 104 extends from the outer shell 102 and is located outside the first cavity 101, for introducing steam. Steam enters through the air inlet 1041 and flows through the steam line 104 within the first passage 201. Several air outlets 1042 are evenly distributed along the circumference of the second overflow pipe 3 and extend through the first overflow pipe 2 within the first cavity 101, uniformly releasing steam into the first cavity 101.

[0056] The advantage lies in the rational layout of steam pipeline 104 and the even distribution of gas outlets 1042, which can provide uniform and efficient heat to the liquid oxygen in coil 103, improving heat exchange efficiency and accelerating the vaporization of the liquid oxygen. The uniform supply of steam helps maintain a stable temperature within vaporizer body 1, reduces the impact of temperature fluctuations on the vaporization process, and ensures stable and continuous production.

[0057] Furthermore, the filter device 8 includes a filter shell 801, which has a second cavity 8011 inside, and the side wall of the filter shell 801 has a third water inlet 8012 and a third water outlet 8013, the third water inlet 8012 is connected to the first water outlet 203, and the third water outlet 8013 is connected to the water inlet of the water collection pool; the filter layer 802 is arranged in the second cavity 8011, between the third water inlet 8012 and the third water outlet 8012.

[0058] In this embodiment, after the scale is cleaned in the vaporizer body 1, the overflow water with scale residue flows out from the first water outlet 203 of the first overflow pipe 2 and then enters the third water inlet 8012 of the filter device 8. In the second cavity 8011 inside the filter shell 801, the filter layer 802 arranged between the third water inlet 8012 and the third water outlet 8013 plays a role. For example, the filter layer 802 is composed of multiple layers of filter screens with different pore sizes and activated carbon and other materials. When the overflow water passes through the filter layer 802, the larger particles of scale residue are intercepted, and the impurities and odors in the water are also adsorbed by the activated carbon. The water after filtration flows out from the third water outlet 8013 and enters the water collection tank 5.

[0059] The advantage is that filter layer 802 can effectively intercept scale residues and impurities of varying sizes, improving filtration accuracy and ensuring the cleanliness of the recovered water. Using multiple layers of filter layer 802 made of different materials simultaneously achieves physical filtration and chemical adsorption, removing a variety of pollutants and improving water quality. Filter housing 801 provides stable support and protection for filter layer 802, ensuring the stability and reliability of the filtration process.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
