Description

Technical Field

[0001] The present invention belongs to the technical field of biopharmaceuticals, and particularly relates to an exhaust gas purification device for biopharmaceuticals. Background Art

[0002] Biopharmaceuticals is the process and industry of producing drugs using biotechnology. It involves using biological systems (such as bacteria, fungi, plants, animal cells, etc.) to produce drugs, usually through genetic engineering, cell culture, and biochemical methods. These drugs may include protein drugs, antibodies, vaccines, gene therapy drugs, etc. A large amount of exhaust gas is generated during the biopharmaceutical process and needs to be treated. Usually, the spray method is adopted, and the organic matter or other substances in the exhaust gas react with the liquid medicine to achieve the effect of purifying the exhaust gas.

[0003] In the Chinese patent with the publication number CN218485455U, an exhaust gas spray tower is mentioned. Its specification discloses that first, the exhaust gas enters the tower body through the intake pipe. When entering, the first filter screen filters the exhaust gas, and the dust in the exhaust gas can be filtered onto its surface. After filtration, the exhaust gas enters the tower body, and then the water pump starts to operate to pump out the liquid in the water tank and transport it through the pipeline, so that the liquid can be transported to the position of the spray holes. Then, the spray holes can normally spray the liquid, and the spray holes are arranged to evenly atomize and spray the liquid. Thus, the sprayed mist can fully contact and absorb the exhaust gas. However, the above solution only simply contacts the exhaust gas with the liquid medicine by spraying to achieve the purification effect. The contact between the exhaust gas and the liquid medicine is not sufficient, and it is impossible to adjust the contact time between the exhaust gas and the liquid medicine in the tank according to the content of organic matter in the exhaust gas. When the concentration of organic matter in the exhaust gas is high, as the exhaust gas continuously surges in, the previously entered exhaust gas easily stays at the top of the tank and has less contact time with the liquid medicine, resulting in incomplete purification. If the content of organic matter in the exhaust gas is low and the concentration is low, the long reaction time of the exhaust gas in the tank causes waste of time and liquid medicine. Summary of the Invention

[0004] The purpose of the present invention is to provide an exhaust gas purification device for biopharmaceuticals to solve the problems in the prior art that the existing purification device is not convenient to adjust the reaction time of the exhaust gas in the tank according to the content of organic matter in the exhaust gas and the contact between the exhaust gas and the liquid medicine is not sufficient.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to Figures 1 - 7 As shown, the present invention provides an exhaust gas purification device for biopharmaceuticals, including a tank body 1. The arc surface of the tank body 1 is connected to an air inlet pipe 11. The top and bottom of the tank body 1 are respectively connected to an air outlet pipe 12, a water inlet pipe 14, and a water outlet pipe 13. After the water inlet pipe 14 is connected to the tank body 1, it is divided into four branch pipes, and each branch pipe is further connected to a plurality of high-pressure nozzles 24. The water inlet pipe 14 can be provided with water source power by a water pump. An adjusting mechanism 2 is provided inside the tank body 1. The adjusting mechanism 2 includes a sleeve 21. The sleeve 21 is fixedly connected inside the tank body 1. The four branch pipes are located inside the sleeve 21. The arc surface of the sleeve 21 is fixedly connected with a filter screen 22. The filter screen 22 serves to facilitate the dripping of the liquid medicine to the bottom of the tank and is discharged from the water outlet pipe 13. The filter screen 22 is in contact with the inner wall of the tank body 1; the end face of the filter screen 22 is fixedly connected with a telescopic plate 23. The arc surface of the sleeve 21 is connected to a plurality of high-pressure nozzles 24. Every four of the plurality of high-pressure nozzles 24 form a group, and multiple groups of high-pressure nozzles 24 are evenly distributed on the arc surface of the sleeve 21. A first motor 25 is installed on the top of the tank body 1. The output end of the first motor 25 is fixedly connected with a threaded rod 26. The arc surface of the threaded rod 26 is threadedly connected with a driving block 27. The bottom of the driving block 27 is fixedly connected with a connecting rod 28. One end of the connecting rod 28 away from the driving block 27 slides through the tank body 1 and is fixedly connected with the telescopic plate 23.

[0023] The telescopic plate 23 is sleeved on the arc surface of the sleeve 21, and the telescopic plate 23 is arranged in a spiral pattern.

[0024] In this embodiment, the telescopic plate 23 can be extended and folded up and down. After being extended, it can play a guiding role for high-concentration waste gas. After being folded, it can enable the low-concentration waste gas to be less restricted by the shielding object and can be discharged quickly. By means of the telescoping of the telescopic plate 23, the length of the telescopic plate 23 can be adjusted according to the content of organic matter in the waste gas, so as to increase or decrease the contact time between the waste gas and the liquid medicine in the tank body 1, improve the purification effect, and the spiral telescopic plate 23 plays a better guiding role for the waste gas, making the waste gas contact the liquid medicine more fully.

[0025] In a further embodiment, referring to Figure 3 , Figure 5 and Figure 7 , an auxiliary mechanism 3 is provided on the inner wall of the tank body 1. The auxiliary mechanism 3 includes a fixing plate 31, the fixing plate 31 is fixedly connected to the side wall of the tank body 1, an electric telescopic rod 32 is fixedly connected to the end face of the fixing plate 31, a support plate 33 is fixedly connected to the output end of the electric telescopic rod 32, a second motor 34 is fixedly connected to the end face of the support plate 33, a circular plate 35 is fixedly connected to the output end of the second motor 34, and a plurality of blades 37 are provided on the end face of the circular plate 35.

[0026] A plurality of third motors 36 are fixedly connected to the end face of the circular plate 35, a plurality of blades 37 are respectively fixedly connected to the output shafts of the plurality of third motors 36, and a cover plate 38 is fixedly connected to one end of the plurality of third motors 36 away from the circular plate 35.

[0027] In this embodiment, the blades 37 can be adjusted to two states under the cooperation of the third motor 36 and the electric telescopic rod 32, which are respectively suitable for the states of high-concentration waste gas and low-concentration waste gas. That is, the third motor 36 can drive the blades 37 to rotate to achieve the effect of adjusting the angle of the blades 37. The outlet of the air outlet pipe 12 is blocked by the adjusted blades 37, so as to further slow down the speed of the waste gas discharged from the tank body 1, enhance the contact time between the waste gas and the liquid medicine in the tank body 1, and improve the purification effect; when the content of organic matter in the waste gas is small, the blades 37 are rotated like a fan blade by the drive of the second motor 34 to accelerate the flow of the waste gas, so that the waste gas is quickly discharged, reducing the contact time between the waste gas and the liquid medicine in the tank body 1, saving more time and accelerating the efficiency.

[0028] In a further embodiment, referring to Figure 2 and Figure 6 , one end of the air outlet pipe 12 away from the tank body 1 is communicated with a heating pipe 4. An electric heating wire 5 is provided on the inner wall of the heating pipe 4, and the shape of the heating pipe 4 is spiral.

[0029] One end of the heating pipe 4 away from the air outlet pipe 12 is communicated with a connecting pipe 6, and one end of the connecting pipe 6 away from the heating pipe 4 is communicated with a cylinder 7, and the cylinder 7 is fixedly connected to the side wall of the tank body 1.

[0030] In this embodiment, by means of the spiral heating tube 4, the flow path of the waste gas can be extended, so that the wet waste gas is heated for a longer time, improving the drying effect. After the purified waste gas is dried, it can avoid the influence on the activated carbon block when the wet waste gas contacts the activated carbon block as much as possible, and affect the service time of the activated carbon block.

[0031] In a further embodiment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a support column 8 is fixedly connected to the inner wall of the cylinder 7, a bearing plate 9 is fixedly connected to the arc surface of the support column 8, and the shape of the bearing plate 9 is spiral.

[0032] A plug plate 101 is provided at the bottom of the cylinder 7, and the plug plate 101 is threadedly connected to the inner wall of the cylinder 7. By setting the threaded connection, the disassembly of the plug plate 101 can be facilitated. A placement hole is opened on the arc surface of the cylinder 7, and a baffle 102 is engaged with the inner wall of the placement hole. The staff can put the activated carbon block from the baffle 102, and the activated carbon block will slide down along the spiral track of the bearing plate 9.

[0033] In this embodiment, by means of the spiral bearing plate 9, the contact time between the waste gas and the activated carbon block can be extended, and the purification effect on the waste gas can be improved to a certain extent. Through the threaded connection between the plug plate 101 and the cylinder 7 and the engagement of the baffle 102, it is convenient for the staff to replace the activated carbon.

[0034] The working principle of the present invention is as follows: When in use, waste gas is introduced into the tank body 1 through the air inlet pipe 11. If the content of organic substances in the waste gas is high, the first motor 25 is started. The first motor 25 drives the threaded rod 26 to rotate, and the driving block 27 drives the connecting rod 28 to move, so that the telescopic plate 23 will expand. Then, the liquid medicine is introduced into the water inlet pipe 14 by the water pump and sprayed out from the high-pressure nozzle 24. At the same time, the electric telescopic rod 32 and the third motor 36 are started. The third motor 36 drives the blades 37 to rotate, so that a plurality of blades 37 move closer in one direction. And through the drive of the electric telescopic rod 32, the blades 37 block the air outlet of the air outlet pipe 12, seal the opening of the air outlet pipe 12, reduce the opening of the air outlet pipe 12, and slow down the speed of the waste gas discharge. After the waste gas enters the tank body 1, it will spiral upward along the direction of the telescopic plate 23. The flow path of the waste gas becomes longer, increasing the time of the waste gas in the tank body 1, enabling it to fully contact with the liquid medicine and improving the purification effect. The wet waste gas discharged from the air outlet pipe 12 will enter the heating pipe 4. After the electric heating wire 5 is powered on, the waste gas in the heating pipe 4 will be dried, and finally enter the cylinder 7. The staff can pre-place activated carbon blocks in the cylinder 7. In this way, the waste gas will spiral downward along the direction of the bearing plate 9, increasing the contact time between the waste gas and the activated carbon blocks. When the content of organic substances in the waste gas is low, the output end of the first motor 25 rotates in the reverse direction, the driving block 27 moves in the reverse direction, so that the telescopic plate 23 folds together. The third motor 36 rotates in the reverse direction, driving the blades 37 back to their original positions. The second motor 34 is started, driving the circular plate 35 to rotate, and it will rotate like a fan blade, accelerating the flow of the waste gas and discharging the waste gas outward. When it is necessary to replace the activated carbon blocks, the plug plate 101 is screwed. The plug plate 101 will fall off from the cylinder 7 by means of the thread, and the activated carbon blocks in the cylinder 7 will slide out downward along the track of the bearing plate 9. When re-placing, the baffle 102 is pulled out, and the activated carbon blocks are loaded into the cylinder 7 through the opening at the baffle 102 until the cylinder 7 is filled.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
