Description

Technical Field

[0001] This utility model relates to a centralized volatilization mechanism, and more particularly to a centralized volatilization mechanism for collecting carbon disulfide. Background Technology

[0002] Carbon disulfide is a common organic solvent and chemical raw material, widely used in industries such as rubber additives, viscose fiber, pesticides, and cellophane. The production, storage, and use of carbon disulfide generate a large amount of exhaust gas, which is highly toxic, flammable, and explosive, posing a significant threat to the environment and human health. Currently, most manufacturers use a vacuum water ring method to collect the exhaust gas, followed by recovery using a process of -20℃ chilled brine condensation + white oil absorption + distillation.

[0003] However, existing exhaust gas collection devices have the following drawbacks: they cannot centrally volatilize and recover the collected carbon disulfide, resulting in decreased collection efficiency. Therefore, it is necessary to design a centralized volatilization mechanism for carbon disulfide collection to solve the aforementioned technical problems. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this invention provides a centralized volatilization mechanism for collecting carbon disulfide.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a centralized volatilization mechanism for collecting carbon disulfide, including an alkaline washing tank, a collection box installed on the top of the alkaline washing tank, an isolation plate between the alkaline washing tank and the collection box, and the isolation plate being movably connected to the collection box through a transmission mechanism.

[0006] An adsorption layer is provided above the isolation plate, which divides the collection box into an upper evaporation chamber and a lower concentration chamber. Heating plates are symmetrically installed on the inner wall of the concentration chamber, and an air outlet is provided on the side wall of the evaporation chamber, which is connected to the condensation mechanism.

[0007] Preferably, the transmission mechanism includes a connecting rod and a rotating disk located on the side of the collection box. A transmission rod is inserted into the center of the rotating disk, and the transmission rod is connected to the isolation plate through the connecting rod.

[0008] Preferably, one end of the connecting rod is formed as a collar, and the other end is fixedly connected to the side of the isolation plate.

[0009] Preferably, a U-shaped connecting part is formed in the middle of the transmission rod, and a collar is fitted on the connecting part; one end of the transmission rod passes through the collection box and extends outward to connect with the output shaft of the motor.

[0010] Preferably, the middle portions of both ends of the isolation plate are rotatably connected to the inner wall of the collection box via rotating shafts.

[0011] Preferably, a protective shell is provided outside the rotating disk, and the motor is mounted on the protective shell.

[0012] Preferably, the condensation mechanism includes a condensation box installed on the side of the collection box, the interior of which forms a condensation cavity, and a condensation pipe is provided in the condensation cavity, with water injection pipes provided at its upper and lower ends respectively.

[0013] Preferably, one end of the condenser tube is connected to the air outlet, and the other end passes through the bottom of the condenser box and extends downward.

[0014] Preferably, the adsorption layer is made of activated carbon.

[0015] The purpose of this invention is to provide a centralized volatilization mechanism for collecting carbon disulfide. By setting a transmission mechanism to adjust the isolation plate, the isolation plate can be opened at intervals, thereby centrally treating the volatilized carbon disulfide in the alkaline washing tank. The carbon disulfide is adsorbed by an adsorption layer, and the adsorption layer is heated to cause the carbon disulfide gas to volatilize. After condensation, liquid carbon disulfide is obtained, thus achieving centralized collection and treatment of volatilized carbon disulfide. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 , Figure 2 The carbon disulfide collection centralized volatilization mechanism shown includes an alkaline washing tank 10, a collection box 2 installed on the top of the alkaline washing tank 10, and an isolation plate 3 between the alkaline washing tank 10 and the collection box 2. The isolation plate 3 is movably connected to the collection box through a transmission mechanism 1.

[0023] The collected exhaust gas is introduced into an alkaline scrubbing tank, where hydrogen sulfide is first removed. Hydrogen sulfide reacts with sodium hydroxide to produce sodium hydrosulfide, resulting in relatively pure carbon disulfide exhaust gas. At this point, the carbon disulfide accumulates below the isolation plate. The isolation plate is opened by a transmission mechanism, allowing the carbon disulfide to be collected in a concentrated manner.

[0024] To improve the collection efficiency of carbon disulfide, an adsorption layer 4 is provided above the isolation plate 3. The adsorption layer 4 is made of activated carbon. The adsorption layer 4 divides the collection box into an upper volatilization chamber 5 and a lower collection chamber 6. Heating plates 7 are symmetrically installed on the inner wall of the collection chamber 6. An air outlet 8 is provided on the side wall of the volatilization chamber 5 and is connected to the condensation mechanism 9.

[0025] The relatively pure carbon disulfide obtained after alkali washing to remove hydrogen sulfide is adsorbed by activated carbon in the adsorption layer. The concentrated cavity is heated by a heating plate, so that the adsorption layer, which has reached saturation with carbon disulfide, is heated and the carbon disulfide volatilizes.

[0026] The isolation plate is opened by the transmission mechanism, allowing the carbon disulfide accumulated in the alkaline washing tank to enter the collection chamber. The carbon disulfide in the collection chamber is adsorbed by the activated carbon in the adsorption layer, and then heated by the heating plate, causing the carbon disulfide in the adsorption layer to volatilize and enter the volatilization chamber. The carbon disulfide accumulated in the volatilization chamber is then collected and recycled.

[0027] By setting up a collection box, carbon disulfide can not only be collected in a centralized manner, but it can also be concentrated in the volatilization chamber, and finally volatilized and condensed, thereby achieving the collection of carbon disulfide.

[0028] Preferably, the transmission mechanism 1 includes a connecting rod 11 and a rotating disk 12 located on the side of the collection box. A transmission rod 13 is inserted into the center of the rotating disk 12, and the transmission rod 13 is connected to the isolation plate via the connecting rod. The specific structure is as follows: Figure 3 As shown.

[0029] The opening and closing of the isolation plate is adjusted by the transmission mechanism to centrally treat the accumulated carbon disulfide. A rotating disk drives the transmission rod to move, which in turn drives the connecting rod to move, and finally the connecting rod drives the isolation plate to move, thus realizing the opening and closing of the isolation plate.

[0030] Furthermore, one end of the connecting rod 11 is formed as a collar 14, and the other end is fixedly connected to the side of the isolation plate.

[0031] The end of the connecting rod forms a collar, which is placed on the transmission rod. The connecting rod is connected to the transmission rod through the collar, so that when the transmission rod rotates, it drives the collar to move. The other end of the connecting rod is connected to one side of the isolation plate. Since the connecting rod is connected to one edge of the isolation plate, when the transmission rod rotates, it can drive the collar to rotate. The collar drives the connecting rod to move up and down. During the movement of the connecting rod, it drives the isolation plate to rotate, thereby realizing the opening and closing of the isolation plate.

[0032] To improve transmission efficiency, a U-shaped connecting part is formed in the middle of the transmission rod 13, and a collar 14 is fitted on the connecting part; one end of the transmission rod 13 passes through the collection box and extends outward to connect with the output shaft of the motor 16.

[0033] A recessed part is formed in the center of the transmission rod, which can limit the collar during rotation and drive the connecting rod to rotate stably. In actual operation, the motor is started, the motor drives the transmission rod to rotate, the transmission rod rotates the rotating disk, and at the same time drives the collar to rotate. Since the collar is fixed to the connecting rod, the rotation of the transmission rod drives the connecting rod to move up and down, thereby driving the isolation plate to move up and down through the connecting rod. Since the connecting rod is connected to one side of the isolation plate, the isolation plate is raised and lowered on one side during the up and down movement of the connecting rod, realizing the opening and closing of the isolation plate.

[0034] Furthermore, the middle portions of both ends of the isolation plate 3 are rotatably connected to the inner wall of the collection box via rotating shafts 15.

[0035] To ensure the stability of the isolation plate's movement, rotating shafts are installed on both sides of the isolation plate, and the isolation plate is movably connected to the collection box through the rotating shafts. This allows the motor to be turned on, and the connecting rod to move through the transmission rod, which in turn drives the isolation plate to rotate. During the rotation of the isolation plate, its two sides separate from the inner wall of the collection box, thereby achieving centralized collection of carbon disulfide accumulated in the alkaline washing tank.

[0036] Furthermore, a protective shell 17 is provided outside the rotating disk 12, and the motor 16 is mounted on the protective shell.

[0037] By installing a protective shell around the rotating disk, not only can the rotating disk be protected and its normal rotation be ensured, but the installation of the motor can also be facilitated.

[0038] To ensure that carbon disulfide gas can be fully accumulated in the alkaline washing tank, a motor is used to make the transmission rod rotate at intervals. This allows the isolation plate to rotate at intervals under the drive of the connecting rod, releasing carbon disulfide gas into the collection box during the opening and closing process.

[0039] Example 2

[0040] A centralized volatilization mechanism for collecting carbon disulfide includes an alkaline washing tank 10, a collection box 2 installed on the top of the alkaline washing tank 10, and an isolation plate 3 between the alkaline washing tank 10 and the collection box 2. The isolation plate 3 is movably connected to the collection box through a transmission mechanism 1.

[0041] The collected exhaust gas is introduced into an alkaline scrubbing tank, where hydrogen sulfide is first removed. Hydrogen sulfide reacts with sodium hydroxide to produce sodium hydrosulfide, resulting in relatively pure carbon disulfide exhaust gas. At this point, the carbon disulfide accumulates below the isolation plate. The isolation plate is opened by a transmission mechanism, allowing the carbon disulfide to be collected in a concentrated manner.

[0042] To improve the collection efficiency of carbon disulfide, an adsorption layer 4 is provided above the isolation plate 3. The adsorption layer 4 is made of activated carbon. The adsorption layer 4 divides the collection box into an upper volatilization chamber 5 and a lower collection chamber 6. Heating plates 7 are symmetrically installed on the inner wall of the collection chamber 6. An air outlet 8 is provided on the side wall of the volatilization chamber 5 and is connected to the condensation mechanism 9.

[0043] The carbon disulfide in the volatilization chamber is recovered by setting up a condensation mechanism. The carbon disulfide in the volatilization chamber enters the condensation mechanism through the gas outlet, thereby realizing the collection of carbon disulfide.

[0044] Specifically, the condensation mechanism 9 includes a condensation box 91 installed on the side of the collection box. A condensation chamber 92 is formed inside the condensation box 91. A condensation pipe 94 is installed inside the condensation chamber 92, and a water injection pipe 93 is installed at its upper and lower ends, respectively.

[0045] A condensation chamber is formed inside the condensation box. Water injection pipes are installed at the upper and lower ends of the condensation chamber to introduce cooling liquid into the condensation chamber.

[0046] Preferably, one end of the condenser tube 94 is connected to the gas outlet, and the other end extends downward through the bottom of the condenser box. The other end of the condenser tube is placed outside the environment for condensing and refluxing volatile substances in the gas.

[0047] In this scheme, during refrigerant recirculation, the gas to be condensed is introduced from the upper end of the condenser tube, while the chilled water is introduced from the lower end of the water injection tube. This increases the contact area between the chilled water and the carbon disulfide gas to be condensed in the water injection tube, thereby increasing the convection area and making it more conducive to the condensation and collection of volatile substances.

[0048] This invention proposes a centralized volatilization mechanism for collecting carbon disulfide. By setting a transmission mechanism to drive the isolation plate to rotate, the centralized collection of carbon disulfide is achieved. Furthermore, by setting a condensation mechanism to condense and collect the carbon disulfide in the volatilization chamber, the collection efficiency is improved.

[0049] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
