Gas cooling and condensation purification device

Abstract

This utility model relates to the field of condensation and purification technology, and discloses a gas cooling, condensation, and purification device. It achieves enhanced heat transfer and droplet aggregation by incorporating a condensation cylinder, a converging groove, a spiral groove, corrugated strips, and a liquid guiding ridge. Gas to be condensed and purified is introduced into the cylinder, and then uniformly dispersed through the converging groove. Upon entering the converging groove, the gas is forced to rotate along the spiral groove, generating centrifugal force and extending the gas residence time, thus improving the contact efficiency between the gas and the cold wall. The gas then contacts the corrugated strips, creating localized turbulence and enhancing heat transfer efficiency. Simultaneously, the corrugated strips' corrugated protrusions intercept tiny droplets, promoting droplet collision and aggregation. The aggregated droplets, under the influence of centrifugal force and gravity, contact the liquid guiding ridge and flow along its line. They then flow to the guide strips, which collect the droplets and direct them into the receiving tank, thus enhancing heat transfer and droplet aggregation.

Description

Technical Field

[0001] This utility model relates to the field of condensation and purification technology, and in particular to a gas cooling, condensation and purification device. Background Technology

[0002] Gas is a shapeless, compressible, and expandable fluid with volume. Gas is a state of matter, and like liquids, it is a fluid: it can flow and deform. In industrial production, gases need to undergo drying and purification processes, requiring gas cooling and condensation purification devices. These devices are based on the differences in the condensation characteristics of substances, using precise cooling to condense target pollutants (such as volatile organic compounds, oil vapors, water vapor, and solvent vapors) from a gaseous state into a liquid or solid state, thereby achieving gas purification and recovery.

[0003] Existing technologies have certain shortcomings in gas cooling, condensation, and purification. For example, traditional devices have low heat transfer efficiency, insufficient contact between the condenser and the gas, and dead zones in the gas flow path, resulting in some gas not being effectively cooled, leading to incomplete condensation of the target pollutants. Furthermore, the transmission device has a weak ability to capture tiny droplets, and some condensate escapes with the purified gas, resulting in a decrease in purification efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a gas cooling, condensation, and purification device that features enhanced condensation, droplet aggregation, cyclone separation, and reflux rinsing, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a gas cooling, condensation and purification device, including a condenser cylinder, a gas cylinder fixedly sleeved on the top of the condenser cylinder, a cyclone separator provided on one side of the condenser cylinder, a transmission channel fixedly connected between the interior of the cyclone separator and the interior of the condenser cylinder, a liquid collection tank threadedly sleeved on the bottom of the condenser cylinder, a threaded outer ring at the bottom of the condenser cylinder, a threaded groove on the inner ring at the top of the liquid collection tank, and the threads of the inner ring at the top of the liquid collection tank and the outer ring at the bottom of the condenser cylinder are compatible.

[0006] By configuring the above structure and coordinating the condenser and the cyclone separator, a synergistic effect of improved heat transfer efficiency and high separation efficiency can be achieved. Through the linkage between the heat transfer, liquid collection, and liquid guiding of the condenser and the secondary separation and reflux scouring between the cyclone separator, the problems of low heat transfer efficiency, insufficient condensation, incomplete gas-liquid separation, and liquid carryover can be solved simultaneously, significantly improving the overall efficiency and stability of the gas condensation purification device.

[0007] Preferably, the condenser cylinder has a uniformly distributed converging groove in a circular shape inside, the inlet diameter of the converging groove is larger than the outlet diameter, the inner wall of the converging groove has a spiral groove, and the converging groove has a uniformly distributed corrugated strip in an arc-shaped array inside, the corrugated strips forming a corrugated plate.

[0008] With the above structural design, the converging groove utilizes the Venturi effect to accelerate gas flow and enhance the turbulence intensity between gases. The actual effect of the corrugated strip is that the gas accelerates at the peak of the spiral wave and forms a low-speed zone at the trough. When the gas passes through the corrugated plate, it affects the local turbulence. At the same time, the corrugated strip can intercept tiny water droplets and promote droplet collision and aggregation.

[0009] Preferably, a liquid guiding ridge is fixedly installed on the bottom wall of the spiral groove. The liquid guiding ridge has a triangular cross-section, and a guide strip is fixedly connected to the bottom of the liquid guiding ridge. Adjacent guide strips are in contact with each other.

[0010] With the above structural design, the agglomerated droplets come into contact with the liquid guiding ridge under the action of centrifugal force and gravity, and flow along the ridge line. Then they flow to the guide strip, where the guide strip gathers the droplets and flows them into the inside of the collection tank for centralized collection.

[0011] Preferably, the cyclone separator has a flow divider inside, and a wire mesh sleeve is threadedly installed at the bottom of the flow divider inside the cyclone separator. The mesh size of the wire mesh sleeve is 800-1000 mesh. A return channel is fixedly connected to the top of the flow divider, and the other end of the return channel is fixedly connected to one side of the air cylinder. The flow divider is connected to the inside of the air cylinder through the other end of the return channel.

[0012] With the above structural setup, the gas rotates inside the cyclone separator, generating centrifugal force that throws most of the droplets toward the inner wall. The water droplets flow along the wall to the bottom of the cyclone separator for collection. The capillary action of the wire mesh sleeve captures the tiny water droplets, improving separation efficiency. After secondary diversion, part of the purified gas is led back into the gas cylinder through the return channel. The returned clean gas can flush away residual droplets and trace impurities on the walls of the converging and spiral grooves.

[0013] This utility model has the following advantages:

[0014] 1. This gas cooling, condensation, and purification device achieves enhanced heat transfer and droplet aggregation through structures such as a condenser cylinder, a converging groove, a spiral groove, corrugated strips, and liquid guiding ridges. The gas to be condensed and purified is introduced into the cylinder, then uniformly dispersed through the converging groove. Upon entering the converging groove, the gas is forced to rotate along the spiral groove, generating centrifugal force and extending the gas residence time, thus improving the contact efficiency between the gas and the cold wall. The gas then contacts the corrugated strips, creating localized turbulence and enhancing heat transfer efficiency. Simultaneously, the corrugated strips' protrusions intercept tiny droplets, promoting droplet collision and aggregation. These aggregated droplets, under the influence of centrifugal force and gravity, contact the liquid guiding ridges and flow along them. They then flow to the guide strips, which collect the droplets and direct them into the collection tank for centralized collection, thus enhancing heat transfer and droplet aggregation.

[0015] 2. This gas cooling, condensing, and purifying device achieves cyclone separation and reflux rinsing through a structure including a cyclone separator, a diverter, a wire mesh sleeve, and a return channel. The condensed gas enters the cyclone separator through a transmission channel. Upon contact with the inner wall of the cyclone separator, the gas rotates, throwing most of the liquid droplets towards the inner wall. The droplets flow along the wall to the bottom of the cyclone separator. A small amount of liquid droplets remain inside the separated gas. When the gas passes through the wire mesh sleeve into the diverter, the wire mesh sleeve captures these tiny liquid particles through capillary action, thus purifying the gas. The purified gas is then diverted through the reflux channel, leading a small amount of gas back into the gas cylinder to mix with the uncondensed gas. The refluxed gas then washes away residual droplets and trace impurities along the spiral groove, while simultaneously diluting the uncondensed gas, achieving a two-stage separation and reflux rinsing effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figures 1-3 A gas cooling, condensation and purification device includes a condenser cylinder 1, a gas cylinder 2 fixedly sleeved on the top of the condenser cylinder 1, a cyclone separator 3 provided on one side of the condenser cylinder 1, a transmission channel 31 fixedly connected between the interior of the cyclone separator 3 and the interior of the condenser cylinder 1, and a liquid collection tank 4 threadedly sleeved on the bottom of the condenser cylinder 1. The outer ring of the bottom of the condenser cylinder 1 is threaded, and the inner ring of the top of the liquid collection tank 4 is threaded. The threads of the inner ring of the top of the liquid collection tank 4 and the outer ring of the bottom of the condenser cylinder 1 are compatible.

[0023] In practical applications, this device, through the structural coordination of the condenser 1 and the cyclone separator 3, can achieve a synergistic effect of improved heat transfer efficiency and high separation efficiency. Through the linkage between the heat transfer, liquid collection, and liquid guidance of the condenser 1 and the secondary separation and reflux scouring between the cyclone separator 3, it can simultaneously solve the problems of low heat transfer efficiency, insufficient condensation, incomplete gas-liquid separation, and liquid carryover, significantly improving the overall efficiency and stability of the gas condensation purification device, and is suitable for various scenarios.

[0024] By supplying gas into the gas cylinder 2, the gas is evenly distributed inside the converging groove 11 for condensation and heat exchange. When the gas enters the converging groove 11, it generates a spiral effect through the spiral groove 12. When the gas flows in a swirling motion, it comes into contact with the corrugated strip 13, which can generate local turbulence in the gas. Combined with the spiral turbulence, it increases the rapid heat transfer of the gas. The droplets generated during condensation are driven by the spiral centrifugal force and gravity, and flow along the ridge line of the liquid guiding ridge 14, which enhances the guiding effect of the droplets. Finally, the droplets will converge at the guide strip 15 and then drip into the liquid collection tank 4.

[0025] Please see Figures 1-3 The condenser 1 has uniformly distributed converging grooves 11 in a circular shape inside. The inlet diameter of the converging groove 11 is 20% larger than the outlet diameter. The Venturi effect is used to accelerate gas flow and enhance the turbulence intensity between gases. The inner wall of the converging groove 11 has spiral grooves 12. The inner wall of the converging groove 11 has a uniformly distributed corrugated strips 13 in an arc-shaped array. The corrugated strips 13 form a corrugated plate. The actual effect is that the gas is accelerated at the peak of the spiral wave and a low-speed zone is formed at the trough. When the gas passes through the corrugated plate, it affects the local turbulence. At the same time, the corrugated strips 13 can intercept tiny water droplets and promote droplet collision and aggregation.

[0026] Please see Figures 1-3A liquid guiding ridge 14 is fixedly installed on the bottom wall of the spiral groove 12. The cross-section of the liquid guiding ridge 14 is triangular. Under the action of centrifugal force and gravity of the spiral, the droplets flow down sequentially along the ridge line of the liquid guiding ridge 14. A guide strip 15 is fixedly connected to the bottom of the liquid guiding ridge 14. The adjacent guide strips 15 are in contact, so that the water droplets converge and flow down.

[0027] Please see Figures 1-4 The hydrocyclone separator 3 has a flow divider 32 inside. A wire mesh sleeve 33 is threadedly installed at the bottom of the flow divider 32 inside the hydrocyclone separator 3. The mesh size of the wire mesh sleeve 33 is 800-1000 mesh. A return channel 34 is fixedly connected to the top of the flow divider 32. The other end of the return channel 34 is fixedly connected to one side of the gas cylinder 2. The flow divider 32 is connected to the inside of the gas cylinder 2 through the other end of the return channel 34. The gas condensed in the condenser 1 enters the hydrocyclone separator 3 through the transmission channel 31. The gas rotates within the hydrocyclone separator 3, generating centrifugal force, which... Some droplets are thrown against the inner wall, and the water droplets flow along the wall to the bottom of the cyclone separator 3 for collection. After cyclone separation, the gas containing a small amount of droplets enters the interior of the diverter 32 through the wire mesh sleeve 33. The capillary action of the wire mesh sleeve 33 captures the tiny water droplets, improving the separation efficiency. 15% of the purified gas after secondary diversion is led back into the interior of the gas cylinder 2 through the return channel 34. The returned clean gas can flush the residual droplets and trace impurities on the walls of the converging groove 11 and the spiral groove 12 to avoid scaling. At the same time, it can dilute the pollutants in the uncondensed gas, reduce their concentration, and indirectly promote subsequent condensation.

[0028] By setting the condenser 1 and the cyclone separator 3, the heat transfer and condensation efficiency can be improved, and the droplet separation efficiency in the gas is also greatly improved. At the same time, the long-term stability of the equipment is extended. Through the closed-loop linkage of enhanced heat transfer, promotion of droplet aggregation, secondary separation of droplets, and reflux dilution, the problems of insufficient heat transfer and incomplete separation are solved, breaking the vicious cycle between the two and achieving a synergistic effect of 1+1>2.

[0029] Working Principle: During operation, the gas to be condensed and purified is introduced into the gas cylinder 2. The gas is then evenly dispersed through the converging groove 11. Upon entering the converging groove 11, the gas is forced to rotate along the spiral groove 12, generating centrifugal force. This also prolongs the gas residence time, improving the contact efficiency between the gas and the cold wall. The gas then contacts the corrugated strips 13 via the spiral, creating localized turbulence and enhancing heat transfer efficiency. Simultaneously, the corrugated protrusions of the corrugated strips 13 intercept tiny droplets, promoting droplet collision and aggregation. These aggregated droplets, under the influence of centrifugal force and gravity, contact the liquid guiding ridge 14 and flow along its ridge line. They then flow to the guide strip 15, which collects the droplets and directs them into the collection tank 4 for centralized collection. The condensed gas enters the cyclone separator 3 through the transmission channel 31. The gas rotates upon contact with the inner wall of the cyclone separator 3, throwing most of the liquid droplets in the gas toward the inner wall. The droplets flow along the wall to the bottom of the cyclone separator 3. A small amount of liquid droplets still remain inside the separated gas. When the gas enters the diverter cylinder 32 through the wire mesh sleeve 33, the wire mesh sleeve 33 captures the tiny liquids in the gas through capillary action, making the gas passing through the wire mesh sleeve 33 clean gas. The purified gas is diverted through the return channel 34, and a small amount of gas is led back into the gas cylinder 2 to mix with the uncondensed gas. The returned gas washes away residual droplets and trace impurities along the spiral groove 12, and at the same time dilutes the uncondensed gas, reducing its pollutant concentration and indirectly promoting subsequent condensation.
