Description

Technical Field

[0001] This utility model belongs to the technical field of protein production process equipment, specifically relating to a protein raw material gas-liquid separator device. Background Technology

[0002] In the protein production process, the raw material gas is usually in a gas-liquid mixed state. If the liquid impurities contained in it (such as moisture, raw material droplets, etc.) are not separated and removed in time, it will adversely affect the stable operation of subsequent production equipment and product quality. Therefore, it is necessary to use a separator to separate the gas and liquid in the protein production raw material gas.

[0003] Currently, most common raw material gas separators rely on the principle of gravity separation, utilizing the density difference between the gas and liquid phases to allow the raw material gas to settle naturally within the tank, while the liquid settles under gravity, achieving separation. However, this separation method has significant shortcomings: firstly, the separation efficiency is low, especially for small droplets, where gravity alone is insufficient for effective settling, resulting in some liquid still entering subsequent stages with the gas; secondly, during the separation process, some liquid adheres to the inner wall of the separator, and existing devices lack specific cleaning structures to promptly remove this adhered liquid. Over time, this not only reduces the effective volume of the tank but may also lead to tank corrosion or microbial growth due to liquid residue, affecting the lifespan of the device and the separation effect, making it difficult to meet the stringent purity requirements of protein production. Utility Model Content

[0004] The purpose of this invention is to provide a gas-liquid separator for protein raw materials, which utilizes centrifugal force to separate the gas and liquid in the raw material gas. During the separation process, a scraper cleans the liquid adhering to the cylinder wall.

[0006] The gas-liquid separation assembly includes a centrifugal separator rotatably installed inside the tank. Several baffles and a wire mesh demister are installed inside the centrifugal separator. A gear ring is installed on the outer wall of the centrifugal separator, with a small gear meshing on one side of the gear ring. A speed-regulating motor is installed at the top of the tank, and a drive shaft is connected below the speed-regulating motor. The small gear is connected to the drive shaft, and a main gear is fixed on the drive shaft. A first driven gear meshes with the main gear. A rotating shaft is fixed to the first driven gear, and a second driven gear is fixed on the rotating shaft. A third driven gear meshes below the second driven gear, and a reciprocating screw is connected below the third driven gear. The reciprocating screw is located inside the centrifugal separator, and a slider is slidably installed on the reciprocating screw. An annular scraper is fixed on the slider, and the annular scraper is in contact with the inner wall of the centrifugal separator. During the rotation of the centrifugal separator, the scraper can move vertically back and forth inside the centrifugal separator.

[0007] Furthermore, the upper end of the tank is cylindrical, and the lower end is funnel-shaped. Several legs are installed on the tank, and each leg is equipped with a caster at its bottom, with a locking mechanism on the caster.

[0008] Furthermore, the centrifugal separator is located in the middle of the tank, and a separator cover is installed on top of the centrifugal separator. The separator cover is fixedly installed below the air outlet pipe, and an air vent is opened on the separator cover. The air vent is connected to the air outlet pipe, and the centrifugal separator is rotatably installed below the separator cover.

[0009] Furthermore, the lower surface of the separation cylinder cover is provided with an annular groove, and the upper edge of the centrifugal separation cylinder is provided with an annular pad, which is stuck in the annular groove and can rotate within the annular groove.

[0010] Furthermore, two cylindrical supports are symmetrically fixed on the inner wall of the tank. The ends of the cylindrical supports are arc plates adapted to the centrifugal separation cylinder, and the centrifugal separation cylinder is rotatably installed between the two cylindrical supports.

[0011] Furthermore, the aforementioned baffles are installed parallel to each other and inclined inside the centrifugal separator. A connecting plate is connected through the middle of the baffles, and the connecting plate is fixed at the upper and lower ends of the centrifugal separator. Each baffle has several small holes. The wire mesh demister is made of multiple layers of interwoven metal wire mesh stacked together, and it is cylindrical.

[0012] Furthermore, a bearing seat is installed on the inner wall of the centrifugal separator, a reciprocating screw is installed on the bearing seat, two fixed seats are installed on the inner wall of the centrifugal separator, a guide rod is fixedly installed between the two fixed seats, a movable block is slidably installed on the guide rod, and an annular scraper is fixed between the slider and the movable block.

[0013] Furthermore, the liquid collection assembly includes a liquid collection tank, an air inlet pipe connected to one side of the liquid collection pipe, the upper end of the liquid collection tank is cylindrical with a diameter slightly larger than that of the centrifugal separator, the lower end of the centrifugal separator is sleeved on the upper cylindrical part of the liquid collection tank, the lower end of the liquid collection tank is funnel-shaped, and the lower end of the liquid collection tank is fixedly connected to the tank body.

[0014] Furthermore, a drain pipe is connected to one side of the collection tank, and a solenoid valve is installed on the drain pipe. An ultrasonic level gauge is installed inside the collection tank.

[0015] Furthermore, a gasket is provided at the lower end of the centrifugal separator, and an annular slide is provided at the upper end of the liquid collection tank. The gasket is locked in the annular slide and can rotate within the annular slide.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: By inputting the raw gas into the centrifugal separator through the inlet pipe, the speed-regulating motor drives the pinion and main gear to rotate. When the pinion rotates, it drives the centrifugal separator to rotate through the gear ring, generating centrifugal force inside the separator and throwing the water in the raw gas to both sides of the separator wall. The gas flows upward and passes through the baffle plate and the wire mesh demister in sequence. When the raw gas comes into contact with these devices, small droplets in the gas are intercepted, and the droplets fall back into the liquid collection component below under the action of gravity and centrifugal force. Some droplets will adhere to the centrifugal separator. At this time, the reciprocating screw can be rotated through the gear meshing relationship, thereby driving the slider and the annular scraper to move vertically back and forth. The water droplets adhering to the inner wall of the centrifugal separator are scraped off. The water droplets will slide down the inner wall of the centrifugal separator to the liquid collection tank, and finally the liquid is discharged from the tank through the drain pipe by the solenoid valve.

[0017] This invention utilizes the centrifugal force generated by the rotation of a centrifugal separator, along with baffles and a wire mesh demister, to separate the gas and liquid in the raw material gas, thereby improving the gas-liquid separation efficiency. During the separation process, a scraper can promptly clean the liquid adhering to the cylinder wall, preventing residual effects. Attached Figure Description

Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] See Figure 1As shown, this utility model provides a gas-liquid separator for protein raw materials, including a tank body 101. A gas-liquid separation assembly is installed inside the tank body 101 to separate the liquid from the gas in the protein raw material gas. A liquid collection assembly is installed below the gas-liquid separation assembly for centralized processing and discharge of the separated liquid.

[0028] The tank 101 described above has a cylindrical upper end and a funnel-shaped lower end. Several support legs 102 are installed on the tank 101, each with a caster 103 at its bottom, and the caster 103 is equipped with a locking mechanism. A downward-sloping air inlet pipe 104 is installed on one side of the tank 101 to prevent the raw material gas from directly impacting the tank wall and causing liquid droplets to splash. An air outlet pipe 105 is vertically installed at the top of the tank 101.

[0029] A gas-liquid separation assembly is installed inside the tank 101, and includes a cylindrical centrifugal separator 201. The centrifugal separator 201 is located in the middle of the tank 101, with its upper and lower ends connected. A separator cover 202 is installed on top of the centrifugal separator 201. The separator cover 202 is fixedly installed below the outlet pipe 105, and there is a certain distance between the separator cover 202 and the top of the tank 101. A vent is provided on the separator cover 202. The vent communicates with the outlet pipe 105, allowing the separated gas to enter the outlet pipe 105 through the separator cover 202. The centrifugal separator 201 is rotatably mounted below the separator cover 202.

[0030] Specifically, an annular gasket is provided on the upper edge of the centrifugal separator 201, and an annular groove is provided on the lower edge of the separator cover 202. The annular gasket is engaged in the annular groove and can rotate within it. Two cylindrical supports 203 extending radially along the inner wall of the tank 101 are fixed on the inner wall of the tank 101. The ends of the cylindrical supports 203 are arc-shaped plates adapted to the outer wall of the centrifugal separator 201. The centrifugal separator 201 is rotatably mounted between the two cylindrical supports 203. The cylindrical supports 203 support the centrifugal separator 201, allowing it to rotate stably. A gear ring 204 is provided on the outer wall of the top of the centrifugal separator 201, and a pinion 205 meshes with one side of the gear ring 204. The pinion 205 is located inside the tank 101. A speed-regulating motor 206 is installed at the top of the tank 101. A drive shaft 207 is connected to the output shaft of the speed-regulating motor 206. The drive shaft 207 passes through the top of the tank 101 and extends into the interior of the tank 101. The pinion 205 is fixedly installed below the drive shaft 207.

[0031] The speed-regulating motor 206 can drive the transmission shaft 207 and the pinion 205 to rotate. Through the meshing relationship between the pinion 205 and the gear ring 204, it can drive the centrifugal separator 201 to rotate. Using centrifugal force, the liquid in the raw material gas entering the centrifugal separator 201 is thrown towards the wall of the centrifugal separator 201 to achieve gas-liquid separation. The separated gas enters the gas outlet pipe 105 through the separator cover 202 and is discharged, while the liquid flows down the cylinder wall and is collected by the liquid collection component.

[0032] Several parallel baffles 208 are installed at the lower end of the centrifugal separator 201, and these baffles 208 are installed at an angle inside the centrifugal separator 201. A connecting plate connects the baffles 208 through the middle of each baffle. The connecting plate is fixed to the inner wall of the upper and lower ends of the centrifugal separator 201. Several small holes are provided on the baffles 208; when the raw gas passes through these holes, it is blocked by the baffles 208. Under the action of centrifugal force, the liquid collides with the baffles 208 and adheres to the surface of the baffles 208 and the inner wall of the centrifugal separator 201, gradually converging into droplets and flowing downwards to the liquid collection assembly.

[0033] Above several baffles 208, a wire mesh demister 209 is installed. The wire mesh demister 209 is made of multiple layers of interwoven metal wire mesh, and its overall shape is cylindrical. When the raw gas passes through the wire mesh demister 209, the tiny droplets remaining in the gas are intercepted by the wire mesh demister 209. After the droplets converge into larger droplets on the wire mesh, they fall into the liquid collection component under the action of gravity and centrifugal force, realizing secondary separation.

[0034] Furthermore, temperature is crucial for gas-liquid separation. Therefore, a temperature sensor and temperature control components are installed inside the tank 101 to regulate the temperature inside the tank to the optimal range in real time, thereby improving the gas-liquid separation effect.

[0035] During gas-liquid separation, some water droplets adhere to the centrifugal separator 201 due to centrifugal force. To remove the water droplets from the inner wall of the centrifugal separator 201, a main gear 210 is fixedly mounted on the drive shaft 207, positioned above the pinion 205. A first driven gear 211 meshes with one side of the main gear 210, and a rotating shaft 214 is fixed to the middle of the first driven gear 211, with the first driven gear 211 located at one end of the rotating shaft 214. A second driven gear 212 is fixed to the other end of the rotating shaft 214. A third driven gear 213 meshes with the second driven gear 212 below it. The third driven gear 213 is located above the separator cover 202. A reciprocating screw 215 is connected to the lower part of the third driven gear 213. The reciprocating screw 215 passes through the separator cover 202 and extends into the centrifugal separator 201. The reciprocating screw 215 is located on one side of the centrifugal separator 201. A matching slider 216 is slidably mounted on the reciprocating lead screw 215. Bearing seats 217 are installed at the upper and lower ends of the inner wall of the centrifugal separator 201. The reciprocating lead screw 215 is installed between the two bearing seats 217.

[0036] Two fixed seats 218 are installed at the upper and lower ends of the inner wall of the centrifuge cylinder 201, and a guide rod 219 is fixedly installed between the two fixed seats 218. A movable block is slidably installed on the guide rod 219. An annular scraper 220 is fixed between the slider 216 and the movable block. The annular scraper 220 is in contact with the inner wall of the centrifuge cylinder 201. The annular scraper 220 is made of rubber. When the reciprocating screw 215 rotates, the slider 216 can drive the annular scraper 220 to move vertically reciprocally, scraping away water droplets on the inner wall of the centrifuge cylinder 201. The scraped water droplets flow along the inner wall of the centrifuge cylinder 201 into the liquid collection assembly.

[0037] The liquid collection assembly includes a collection tank 301, which is installed below a centrifugal separator 201. An air inlet pipe 104 is connected to one side of the collection tank. The upper end of the collection tank 301 is cylindrical, with a diameter slightly larger than that of the centrifugal separator 201. The lower end of the centrifugal separator 201 is fitted onto the upper cylindrical portion of the collection tank 301. A gasket is provided at the lower end of the centrifugal separator 201, and an annular slide is provided at the upper end of the collection tank 301. The gasket is engaged within the annular slide and can rotate within it. The lower end of the collection tank 301 is funnel-shaped and is fixedly connected to the tank body 101. A drain pipe 302 is connected to one side of the collection tank 301, and a solenoid valve 303 is installed on the drain pipe 302. Furthermore, an ultrasonic level gauge is installed inside the collection tank 301 to detect the water level. When the ultrasonic level gauge detects that the liquid level has reached the set upper limit, it sends a signal to control the solenoid valve 303 on the drain pipe 302 to open, and the liquid can be discharged from the tank 101 through the solenoid valve 303.

[0038] Example: Raw material gas is fed into centrifugal separator 201 through inlet pipe 104. Speed-regulating motor 206 drives pinion 205 and main gear 210 to rotate. When pinion 205 rotates, it drives centrifugal separator 201 to rotate via gear ring 204, generating centrifugal force inside the separator and throwing water from the raw material gas towards both sides of the separator wall. The gas flows upward, passing sequentially through baffle 208 and wire mesh demister 209. Contact with these baffles intercepts small droplets, which fall back into the liquid collection assembly below under the influence of gravity and centrifugal force. Some droplets adhere to centrifugal separator 201. At this point, the gear meshing drives reciprocating screw 215 to rotate, thereby causing slider 216 and annular scraper 220 to move vertically back and forth, scraping away water droplets adhering to the inner wall of centrifugal separator 201. Water droplets will slide down the inner wall of the centrifugal separator 201 to the collection tank 301, and finally the liquid will be discharged from the tank 101 through the drain pipe 302 via the solenoid valve 303.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
