Description

Technical Field

[0001] This utility model belongs to the field of exhaust gas collection technology and relates to an exhaust gas collection device. Background Technology

[0002] The production of F113A involves two steps: the first step uses tetrachloroethylene, chlorine, and anhydrous hydrogen fluoride as raw materials, with antimony pentachloride as a catalyst, to produce F113 via a two-step liquid-phase reaction; the second step involves the isomerization of F113 to produce F113A. The tail gases generated in both steps are recovered by their respective recovery systems, and the remaining gaseous phase is discharged to a tail gas alkaline scrubbing tower for destruction and absorption, resulting in significant material waste. Therefore, a tail gas collection device is needed to further collect the materials in the tail gas.

[0003] A butanol and octanol tail gas condensation and recovery device disclosed in Chinese patent CN222445426U includes a condenser cylinder, a liquid chamber in the middle of the condenser cylinder, a bottom plate fixedly connected to the bottom of the condenser cylinder, a top plate fixedly connected to the top of the condenser cylinder, an air inlet pipe fixedly connected to the middle of the top plate, an annular pipe arranged on the upper side of the top plate corresponding to the outside of the air inlet pipe, a liquid inlet pipe fixedly connected to the right side of the annular pipe, and multiple spiral pipes arranged on the inner side of the condenser cylinder, the top of the spiral pipes passing through the upper side of the top plate and fixedly connected to the lower side of the annular pipe.

[0004] The recovery device injects exhaust gas into the condenser cylinder through the inlet pipe, where the exhaust gas enters for condensation. However, when the spiral tube condenses the exhaust gas, the large volume and high temperature of the exhaust gas can cause the spiral tube to condense in a timely manner, reducing its working efficiency.

[0005] To address the aforementioned problems, this utility model proposes an exhaust gas collection device. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes an exhaust gas collection device.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a condenser cylinder, a partition plate is fixedly connected to the middle of the condenser cylinder, a plurality of through holes are evenly opened on the partition plate, a second one-way valve is fixedly installed inside each through hole, and a rotating shaft is rotatably connected inside the condenser cylinder, the rotating shaft rotatably passes through the partition plate.

[0008] A condenser assembly is provided on the shaft at the bottom of the partition. A reciprocating thread is provided on the outer surface of the shaft at the top of the partition. A piston is fitted on the reciprocating thread by a nut. The piston is vertically slidably connected to the inside of the condenser cylinder.

[0009] An air inlet pipe is fixedly inserted through the top of the partition on the side of the condenser cylinder, and a first one-way valve is installed on the air inlet pipe.

[0010] Furthermore, the cavity located at the top of the partition plate inside the condenser cylinder is the first cavity, and the piston is slidably disposed inside the first cavity. The cavity located at the bottom of the partition plate inside the condenser cylinder is the second cavity, and the condensation assembly is located inside the second cavity.

[0011] Furthermore, two limiting strips are symmetrically fixedly connected to the inner wall of the first cavity, and the bottom end of the limiting strips is fixedly connected to the top of the partition. Two grooves adapted to the limiting strips are opened on the piston, and the grooves slide in contact with the limiting strips.

[0012] Furthermore, a motor is fixedly connected to the bottom of the condenser cylinder, and the bottom end of the rotating shaft rotates through the bottom surface of the condenser cylinder and is fixedly connected to the output end of the motor.

[0013] Furthermore, the second one-way valve allows gas in the first cavity to enter the second cavity, and the first one-way valve allows external gas to enter the first cavity. A pressure stabilizing pipe is fixedly connected to the top of the condenser cylinder, and the bottom end of the pressure stabilizing pipe is connected to the first cavity.

[0014] Furthermore, the condensation assembly includes a condenser tube, which is spirally sleeved on the outside of the rotating shaft, with one end of the top of the condenser tube fixedly penetrating the side of the condenser cylinder;

[0015] The condenser cylinder has an annular condensation chamber on its side. The top of the condensation chamber is fixedly connected to a water outlet pipe, and the bottom of the condensation pipe extends through the side of the condenser cylinder and into the bottom of the condensation chamber.

[0016] Furthermore, an exhaust pipe is fixedly installed inside the condensation chamber.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The exhaust gas collection device is equipped with a piston. When the motor drives the rotating shaft to rotate, the reciprocating thread will drive the piston to move downward, so that the exhaust gas in the first cavity enters the second cavity through several through holes. Since the diameter of the through holes is small, the exhaust gas will be cooled when it passes through, and the speed of the exhaust gas entering the second cavity will be slowed down, so that the condenser can fully condense the exhaust gas and improve the working efficiency.

[0021] 2. The exhaust gas collection device is equipped with a piston. By moving the piston up and down, the exhaust gas intermittently enters the second cavity. When no exhaust gas is introduced, the second cavity can cool down automatically to facilitate better condensation.

[0022] 3. The exhaust gas collection device is equipped with a rotating shaft. When the rotating shaft drives the fan blades to rotate, the reciprocating thread can drive the piston to move up and down, eliminating the need to drive the fan blades and pistons separately, thus reducing production costs.

[0028] 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.

[0029] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a tail gas collection device, including a condenser cylinder 1, and a partition 12 is fixedly connected in the middle of the condenser cylinder 1.

[0030] The cavity located at the top of the partition 12 inside the condenser cylinder 1 is the first cavity 101. The cavity located at the bottom of the partition 12 inside the condenser cylinder 1 is the second cavity 102. The partition 12 divides the cavity inside the condenser cylinder 1 into two parts.

[0031] A plurality of through holes 13 are evenly provided on the partition plate 12, so that the first cavity 101 and the second cavity 102 are connected through the through holes 13.

[0032] A second one-way valve 14 is fixedly installed inside each through hole 13. The second one-way valve 14 allows gas in the first cavity 101 to enter the second cavity 102.

[0033] An air inlet pipe 2 is fixedly inserted through the side of the condenser cylinder 1 at the top of the partition plate 12. The air inlet pipe 2 is located at the bottom of the first cavity 101 so that the exhaust gas can be introduced into the first cavity 101 through the air inlet pipe 2.

[0034] The intake pipe 2 is equipped with a first one-way valve 3. The first one-way valve 3 allows external gas to enter the first cavity 101, so that the exhaust gas in the first cavity 101 can only enter the second cavity 102.

[0035] The condenser 1 is internally connected to a rotating shaft 9, which rotates through the partition 12.

[0036] A motor 8 is fixedly connected to the bottom of the condenser cylinder 1, and the bottom end of the rotating shaft 9 rotates through the bottom surface of the condenser cylinder 1 and is fixedly connected to the output end of the motor 8. The motor 8 drives the rotating shaft 9 to rotate.

[0037] A condenser assembly is installed on the rotating shaft 9 at the bottom of the partition 12. The condenser assembly is located inside the second cavity 102. The condenser assembly condenses the exhaust gas, so that the material in the exhaust gas can be condensed and collected.

[0038] The condensation assembly includes a condenser tube 5, which is spirally sleeved around the outside of the rotating shaft 9. One end of the top of the condenser tube 5 is fixedly inserted through the side of the condenser cylinder 1. Condensate is introduced into the interior of the condenser tube 5 through the end of the condenser tube 5 that extends outside the condenser cylinder 1.

[0039] A ring-shaped condensing chamber 6 is formed on the side of the condensing cylinder 1, and a water outlet pipe 7 is fixedly connected to the top of the condensing chamber 6. The bottom end of the condensing pipe 5 is fixedly inserted through the side of the condensing cylinder 1 and extends into the bottom of the condensing chamber 6. This allows the condensate in the condensing pipe 5 to enter the condensing chamber 6 and then be discharged through the water outlet pipe 7.

[0040] Several crossbars are uniformly fixedly connected to the rotating shaft 9 located in the second cavity 102, and a fan blade 15 is fixedly connected to the end of each crossbar. The fan blades 15 are all located inside the condenser tube 5. The rotating shaft 9 drives the fan blades 15 to rotate, and the fan blades 15 agitate the exhaust gas in the second cavity 102, promote the flow of exhaust gas in the second cavity 102, and accelerate the condensation speed of the exhaust gas.

[0041] An exhaust pipe 16 is fixedly installed inside the condenser chamber 6. One end of the exhaust pipe 16 is fixedly inserted through the side of the condenser cylinder 1 and extends to the outside of the condenser cylinder 1, while the other end of the exhaust pipe 16 is fixedly inserted through the side of the condenser cylinder 1 and extends into the interior of the second cavity 102. The exhaust gas in the second cavity 102 is discharged through the exhaust pipe 16 and collected for subsequent treatment.

[0042] A reciprocating thread 10 is formed on the outer surface of the rotating shaft 9 at the top of the partition plate 12. A piston 11 is fitted onto the reciprocating thread 10 by a nut. A steel ball is used as a rolling element between the nut and the reciprocating thread 10, so that the reciprocating thread 10, the nut and the steel ball form a ball screw pair.

[0043] The piston 11 is vertically slidably connected to the inside of the condenser cylinder 1. The piston 11 is slidably disposed inside the first cavity 101.

[0044] Two limiting strips 19 are symmetrically fixedly connected to the inner wall of the first cavity 101, and the bottom end of the limiting strips 19 is fixedly connected to the top of the partition plate 12. Two grooves adapted to the limiting strips 19 are formed on the piston 11, and the grooves slide in contact with the limiting strips 19. The movement of the piston 11 is positioned by the cooperation between the grooves and the limiting strips 19, so that the reciprocating thread 10 drives the piston 11 to move up and down when it rotates.

[0045] A pressure stabilizing pipe 4 is fixedly connected to the top of the condenser cylinder 1, and the bottom end of the pressure stabilizing pipe 4 is connected to the first cavity 101. The pressure stabilizing pipe 4 connects the cavity at the top of the piston 11 with the outside air. When the piston 11 moves inside the first cavity 101, the pressure stabilizing pipe 4 stabilizes the pressure in the cavity at the top of the piston 11.

[0046] A discharge pipe 17 is fixedly connected to the bottom of the condenser 1, and a valve 18 is installed on the discharge pipe 17. This allows the material in the exhaust gas to fall into the second cavity 102 after condensation, and the discharge pipe 17 can discharge the material.

[0047] Working principle:

[0048] In use, connect one end of the intake pipe 2 to the exhaust outlet. Allow the condensate from the end of the condenser pipe 5 extending outside the condenser cylinder 1 into the condenser pipe 5. The condensate inside the condenser pipe 5 will then enter the condensation chamber 6 and be discharged through the water outlet pipe 7.

[0049] Start motor 8, which drives shaft 9 to rotate. Shaft 9 then drives fan blade 15 to rotate.

[0050] The rotating shaft 9 drives the reciprocating thread 10 to rotate, and the reciprocating thread 10 drives the piston 11 to move upward inside the first cavity 101. At the same time, the groove on the piston 11 slides on the corresponding limiting strip 19.

[0051] When piston 11 moves upward, exhaust gas enters the first cavity 101 through intake pipe 2 and is located at the bottom of piston 11. Gas located at the top of piston 11 is discharged through pressure regulating pipe 4.

[0052] After piston 11 moves to the top of reciprocating thread 10, it continues to move downwards. Piston 11 compresses the exhaust gas, causing it to enter the second cavity 102 through through hole 13. External gas enters the cavity at the top of piston 11 through pressure regulating pipe 4.

[0053] When the exhaust gas passes through the through-hole 13, its temperature decreases due to the small diameter of the through-hole 13, thus providing initial cooling. The condenser tube 5 then condenses the exhaust gas. The rotation of the fan blade 15 also agitates the exhaust gas, allowing more of it to contact the condenser tube 5 and improving condensation efficiency.

[0054] After condensation, the material in the exhaust gas falls to the bottom of the second cavity 102. The gas in the exhaust gas is discharged through the exhaust pipe 16, and the exhaust gas is collected. Opening the valve 18 allows the material to be discharged from the discharge pipe 17, and the material in the exhaust gas is collected.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
