Description

Technical Field

[0001] The invention relates to the technical field of air-temperature gasifiers, and in particular to an air-temperature gasifier which is convenient for heat exchange temperature regulation. Background Art

[0002] Air-temperature vaporizer is a device that uses natural convection of air to heat cryogenic liquid to vaporize it into gas. When cryogenic liquid (such as liquefied natural gas, liquid nitrogen, etc.) enters the aluminum finned tube of the air-temperature vaporizer, the surrounding air will exchange heat with the finned tube through natural convection. The heat of the air is transferred to the cryogenic liquid, causing its temperature to gradually increase and vaporize into gas. The vaporized gas flows out from the outlet joint and enters the subsequent transportation pipeline.

[0003] In conjunction with the above content, it should be noted that: the Chinese patent with the announcement number CN115585690B discloses an air-temperature vaporizer, which covers and protects the heat exchanger through a box body, dries and filters the external airflow through a drying box and a filter, and is used in conjunction with an electrically controlled cleaning mechanism to defrost and remove impurities from the surface of the internal heat exchange components of the air-temperature vaporizer. During the actual use of the above components, the external air is restricted by the narrow inlet and outlet area, resulting in uncontrollable contact with the internal heat exchange components, and the suction of the external air by electrical appliances and the electric defrosting both generate additional large operating costs;

[0004] The Chinese patent with the announcement number CN112212211B discloses an air-temperature vaporizer spray device, which uses a spray pipe that moves back and forth up and down. The spray pipe can evenly spray the entire vaporizer pipe to maintain the same temperature at the top and bottom of the vaporizer pipe, ensure the temperature is consistent during the vaporization process, and achieve precise control of the temperature of the vaporizer pipe, thereby ensuring the vaporization efficiency. However, due to the flow of cold medium in the heat exchange component of the air-temperature vaporizer and the absorption of heat from the external air and water, combined with residual water stains from the spray, frost is easily generated on the outside of the heat exchange component, thereby affecting the subsequent heat exchange efficiency;

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0016] The present invention also proposes a working method of an air-temperature gasifier which is convenient for heat exchange temperature control, comprising the following steps:

[0017] S1: Cross-shaped liquid flow heat exchange, the cold medium is first dispersed into the cross-shaped fins along the inside of the water inlet column 1, and then flows along the inside of the fins to the water outlet column 1. The collecting pipe rack collects the cold medium after the flowing heat exchange. The cross-shaped heat exchanger located at the corner of the vaporizer is easy to contact the natural flow of air in more directions. Combined with the cross-shaped heat exchanger structure, the heat exchange efficiency of the cold medium flowing inside it is stable;

[0018] S2: Rotating liquid flow heat exchange, the external pump guides the cold medium into the spiral plate through the cold medium input pipe, the water guide frame and the second water inlet column. The cold medium flows along the spiral track from bottom to top inside the spiral plate, and finally enters the collecting pipe frame through the second water outlet column;

[0019] S3: Air flow screening. When the naturally flowing air passes through the gasifier, an external filter with an appropriate aperture size is installed between the supporting cone plate and the extension frame, and laid flat on the top of the top frame according to the installation environment, so as to achieve comprehensive protection of the outside of the gasifier and intercept the large impurities in the naturally flowing air that affect the operation of the gasifier. Regular inspection and cleaning are sufficient.

[0020] S4: reciprocating movement trajectory, the lifting hydraulic cylinder drives the connecting rod to slide up and down along the inside of the lifting guide column, and the connecting rod drives the moving frame to move synchronously, keeping the whole moving frame moving up and down stably along the outer periphery of the lifting guide column;

[0021] S5: Defrost with a cross-section, the scraper assembly follows the moving frame and slides back and forth up and down along the surface of the cross-section heat exchanger, and the protective assembly and the rectangular assembly are pulled by the moving frame and move back and forth up and down along the surface of the cross-section heat exchanger with a micro-spacing;

[0022] S6: Spiral spray defrosting, the rotating frame group follows the moving frame to slide back and forth up and down along the surface of the spiral heat exchanger, the booster water pump is connected to the water spray ring through the pipe fitting, and the clean water filtered in the water storage chamber is guided to spray on the surface of the spiral blade to flush and clean the surface of the spiral blade;

[0023] When the water spray ring sprays clean water on the spiral blade, the frost and impurities on the surface of the spiral blade are soaked and softened. As the stabilizing sleeve follows the movement of the moving frame, the inner scraping strip is attached to the upper and lower surfaces of the spiral blade. The inner scraping strip is driven by the moving frame to slide along the surface of the spiral blade, scraping off most of the water stains attached to the spiral blade.

[0024] The beneficial effects of the present invention are:

[0025] 1. The present invention uses the cross-shaped heat exchanger and the spiral heat exchanger to cooperate with each other, and utilizes the cross-shaped heat exchanger to fully contact the multi-directional natural flow of air at the corner area of ​​the outer periphery of the vaporizer to improve the contact heat exchange efficiency between the two. The spiral heat exchanger is arranged in the middle area of ​​the vaporizer, and the air flow trajectory is affected by the arrangement angle of the spiral blades of the main body without hindering its flow efficiency, thereby improving the stable contact heat exchange efficiency between the air entering the vaporizer and the spiral heat exchanger, and avoiding the local air being blocked by the flow and staying in the local area, resulting in a constant temperature difference in the area and affecting the heat exchange efficiency;

[0026] 2. The present invention drives the scraper assembly and the rotating frame group to move back and forth up and down along the inside of the vaporizer by a mobile frame, and utilizes the micro-distance interval between the scraper frame group and the outside of the cross-shaped heat exchanger to scrape off frost and impurities on the surface of the cross-shaped heat exchanger to maintain its continuous heat exchange performance. A water spray ring is used to spray clean water on the surface of the spiral blade at a micro-distance, so that frost and impurities on the surface of the spiral blade are soaked and softened, and the inner scraper strip is used to physically contact them to cause them to quickly detach from the spiral blade, which can not only keep the surface of the spiral blade clean and the heat exchange performance, but also utilize the residual hydrogel layer to accelerate the heat exchange conduction between the air, the spiral blade and the cold medium, so that the heat exchange temperature of the vaporizer can be regulated and stabilized.

The top of the water collection tank 1 is provided with a cross heat exchanger 2 and a spiral heat exchanger 3, and the top of the cross heat exchanger 2 is provided with a top frame 4;

[0041] A water guide frame 101 is provided at the top center of the water collecting tank 1, and a water filter tank 102 is provided on the periphery of the water guide frame 101. A cold medium input pipe connecting the water inlet column 1 201 and the water inlet column 2 301 is provided inside the water guide frame 101.

[0042] The sewage collected in the water collection tank 1 is collected along the water guide frame 101 and flows into the water filter layer. A multi-layer filtering structure is embedded inside the water filter layer. Impurities are intercepted at the top of the water filter tank 102. Clean water penetrates into the water storage chamber and is scraped by frost, which causes the water volume in the water collection tank 1 to continue to increase. It is continuously discharged through the water exchange valve to keep the clean water in the water storage chamber constant at a certain amount. The clean water in the water storage chamber and the filtering structure at the top of the water filter tank 102 are regularly replaced.

[0043] A water inlet column 201 is arranged at the bottom of the cross-shaped heat exchanger 2, and a plurality of groups of fins 202 arranged in a circular array are arranged at the top of the water inlet column 201. A water outlet column 203 is arranged at the top of the fin 202. The cold medium is first dispersed into the multiple fins 202 along the inside of the water inlet column 201. The fins 202 are rectangular and form a cross-shaped cross with the water inlet column 201 as the central axis in a circular array. The cold medium flows along the inside of the fin 202 to the water outlet column 203. The top of the water outlet column 203 is connected to the bottom pipeline of the collecting pipe rack 404, and the cold medium after the flowing heat exchange is collected. The cross-shaped heat exchanger 2 located at the corner of the gasifier is easy to contact the natural flow of air in more directions. Combined with the cross-shaped heat exchanger 2 structure, it is helpful to maintain the heat exchange efficiency of the cold medium flowing inside it stable.

[0044] A water inlet column 301 is provided at the bottom of the spiral heat exchanger 3, and a spiral sheet 302 is provided at the top of the water inlet column 301, and a water outlet column 303 is provided at the top of the spiral sheet 302.

The cold medium flows along the spiral trajectory from bottom to top inside the spiral sheet 302, and finally enters the collecting pipe rack 404 through the water outlet column 303. Affected by the structure and installation angle of the spiral sheet 302, the natural flow of air is promoted to flow between the spiral sheets 302 in an offset manner without flow obstruction and direct current, which is conducive to improving the full contact and heat exchange between the cold medium and the natural flow of air inside the spiral heat exchanger 3, thereby improving the heat exchange efficiency of the cold medium and ensuring that the heat exchange temperature can be regulated and kept constant within a certain temperature range. A converging pipe connected to the external heat medium storage box is provided on the top of the collecting pipe rack 404, and the medium collected after heat exchange in the M-shaped heat exchanger 2 and the spiral heat exchanger 3 is centrally transported.

[0046] An extension frame 402 connected to the top of the outer filter screen 5 is arranged on the outer periphery of the top frame 4, a pyramid frame 403 connected to the corner of the top frame 4 is arranged on the top of the lifting guide column 401, and a plurality of collection pipe frames 404 are arranged on the inner wall of the top frame 4;

[0047] A slide groove 407 is provided through the middle of the lifting guide column 401, and lifting hydraulic rods 408 are provided on the inner walls on both sides of the slide groove 407. A central guide rod 409 is provided in the center of the slide groove 407. A connecting sleeve rod 406 sleeved with the central guide rod 409 is provided on the inner wall of the corner of the mobile frame 405. A driving element connected to the lifting hydraulic cylinder is arranged side by side on the side of the booster water pump. The lifting hydraulic cylinder drives the connecting sleeve rod 406 to slide up and down along the lifting guide column 401. The connecting sleeve rod 406 is limited by the central guide rod 409 to maintain initial stability. Under the synergistic effect of the four-point limit of the corners of the mobile frame 405 by multiple groups of connecting sleeve rods 406, the connecting sleeve rod 406 drives the mobile frame 405 to move synchronously, so as to keep the overall mobile frame 405 to make stable up and down reciprocating movement along the periphery of the lifting guide column 401;

[0048] The scraper assembly 6 includes a protective assembly 601, a rectangular assembly 602 is arranged on the cross section of the protective assembly 601, and a connecting frame 603 is arranged on the outer wall of the rectangular assembly 602. The scraper assembly 6 is connected to the mobile frame 405 through the connecting frame 603, and follows the mobile frame 405 to slide back and forth along the surface of the cross-shaped heat exchanger 2. The protective assembly 601 and the rectangular assembly 602 are arranged to form a cross-shaped structure, and there is a hollow state between the protective assembly 601 and the rectangular assembly 602. The protective assembly 601 and the rectangular assembly 602 are pulled by the mobile frame 405 to move back and forth up and down along the surface of the cross-shaped heat exchanger 2 at a micro-spacing, and the frost and impurities generated by heat exchange on the surface of the cross-shaped heat exchanger 2 are scraped and cleaned. Impurities smaller than the mesh of the outer filter 5 in the naturally flowing air are directly generated after contacting the frost;

[0049] The rotating frame group 7 includes a stabilizing sleeve 701, a connecting frame 2 702 is arranged on the outer wall of the stabilizing sleeve 701, an inner rotating ring 704 is sleeved on the inner wall of the stabilizing sleeve 701, and an inner scraper strip 705 is arranged on the inner wall of the inner rotating ring 704. The rotating frame group 7 is connected to the moving frame 405 through the connecting frame 2 702, and follows the moving frame 405 to slide back and forth along the surface of the spiral heat exchanger 3. The booster water pump is connected to the water spray ring 703 through a pipe fitting. During the period when the booster water pump follows the moving frame 405 to move up and down, the filtered clean water in the water storage chamber is guided and sprayed on the surface of the spiral plate 302. The surface of the spiral plate 302 is attached by the clean water. First, the surface of the spiral plate 302 is flushed and cleaned to keep the surface of the spiral plate 302 clean. The hydrogel layer formed by the attachment of water stains is used in conjunction with the spiral plate 302 to increase the heat exchange efficiency between the cold medium flowing in the spiral plate 302 and the naturally flowing air.

[0050] A water spray ring 703 is provided at the bottom of the stabilizing sleeve 701. When the water spray ring 703 sprays clean water on the spiral piece 302, the frost on the surface of the spiral piece 302 is soaked and softened. As the stabilizing sleeve 701 follows the movement of the moving frame 405, the inner scraper bar 705 is attached to the upper and lower surfaces of the spiral piece 302. The inner scraper bar 705 is driven by the moving frame 405 to slide along the surface of the spiral piece 302. The inner scraper bar 705 is pulled by the inner rotating ring 704 to keep rotating synchronously along the inside of the stabilizing sleeve 701, thereby scraping off most of the water stains attached to the spiral piece 302, leaving a small amount of thin layer of hydrogel. At the same time, the inner scraper bar 705 contacts along the surface of the spiral piece 302, causing the soaked and softened frost and impurities on its surface to be scraped off. As the curvature of the surface of the spiral piece 302 and the traction of the inner scraper bar 705 body, a mixture of the soaked and softened frost, impurities and water falls into the water collecting tank 1 along the edge of the spiral piece 302 and the bottom of the inner scraper bar 705.

[0051] Combining the first and second embodiments, it can be known that the cross-shaped heat exchanger 2 is used to fully contact the multi-directional naturally flowing air with the corner area of ​​the outer periphery of the vaporizer to improve the contact heat exchange efficiency between the two. The spiral heat exchanger 3 is arranged in the middle area of ​​the vaporizer, and the air flow trajectory is affected by the arrangement angle of the spiral blades 302 of the main body without hindering its flow efficiency, thereby improving the stable contact heat exchange efficiency between the air entering the vaporizer and the spiral heat exchanger 3, avoiding local air from being blocked by flow and being retained in the local area, resulting in a constant temperature difference in the area and affecting the heat exchange efficiency, and achieving the scraping of frost and impurities on the surface of the cross-shaped heat exchanger 2 to maintain its continuous heat exchange performance;

[0052] The water spray ring 703 is used to spray clean water at a micro-distance on the surface of the spiral blade 302, so that the frost and impurities on the surface of the spiral blade 302 are soaked and softened, and the internal scraper 705 makes physical contact with them to cause them to quickly detach from the spiral blade 302, which can not only keep the surface of the spiral blade 302 clean and the heat exchange performance can be maintained, but also use the residual hydrogel layer to accelerate the heat transfer conduction between the air, the spiral blade 302 and the cold medium, so that the heat exchange temperature of the vaporizer can be regulated and stabilized.
