Description

Technical Field

[0001] This invention relates to the field of hand sanitizer production technology, specifically to an odor adsorption and purification device for the hand sanitizer production process. Background Technology

[0002] Hand sanitizer production primarily uses surfactants, fragrances, alcohols, and preservatives as raw materials. During the mixing, stirring, emulsification, and filling processes, hand sanitizer continuously releases odorous gases and VOCs, including alcohols, esters, fragrances, and surfactants. These gases are characterized by high humidity, easy foaming, low odor threshold, and large air volume, easily causing unpleasant odors in the workshop and disturbing residents at the factory boundary. Currently, the high-temperature exhaust gases generated during hand sanitizer production are often treated using a combination of spray washing and adsorption.

[0003] However, existing spray systems are susceptible to problems during operation. If a water pump malfunctions, the water supply is interrupted, or the nozzles become clogged, the spraying process will stop, but the equipment may continue running, resulting in the direct emission of untreated high-temperature exhaust gas and causing pollution. Furthermore, if the liquid droplets entrained in the exhaust gas after spraying are not completely removed, it will severely affect the efficiency and lifespan of subsequent adsorption units. Additionally, replacing the adsorption material is inconvenient, and odors are prone to backflow from the purified exhaust port. Therefore, these systems do not meet current requirements. To address this, we propose an odor adsorption and purification device for the hand sanitizer production process. Summary of the Invention

Furthermore, a movable cleaning mechanism automatically scrapes away accumulated dirt on the surface of the wire mesh demister plate periodically, preventing blockage and maintaining long-term stable demister efficiency while reducing the frequency and difficulty of manual cleaning.

[0030] Please see Figures 1 to 7 An embodiment of the present invention provides an odor adsorption and purification device for a hand sanitizer production process, comprising a cooling box 2, a defoaming box 3, and an adsorption device 4. An air pump 7 for drawing out waste gas is installed on one side of the cooling box 2. Multiple flow-blocking plates 8 are fixedly connected to the inner wall of the cooling box 2 and are arranged in an alternating manner. A high-pressure nozzle is provided below each flow-blocking plate. A gravity alarm mechanism 10 is installed on one side of the upper end face of at least one flow-blocking plate 8.

A wire mesh demister plate 18 is installed on the inner side of the housing 6. A cleaning mechanism 19 is provided above the wire mesh demister plate 18. A draining mechanism 15 is installed below the housing 6.

[0032] The adsorption device 4 includes an adsorption cylinder 401, a rotating cover plate 402 is threadedly connected to the upper part of the adsorption cylinder 401, a cylinder body 16 is provided on the lower end face of the rotating cover plate 402, an exhaust pipe 17 is provided on the rear end face of the rotating cover plate 402, and a sealing mechanism 23 is installed on the inner side of the exhaust pipe 17.

[0033] The air pump 7 has an air inlet end connected to a gas collection hood 1 extending to the exhaust gas source.

The drainage mechanism 15 includes a flow guide box, a drainage pipe is installed on the lower end face of the flow guide box, and a solenoid valve is installed on the inner side of the drainage pipe.

A second electrode plate 1004 is installed at the corresponding position on the upper end face of the flow-blocking plate 8. When the water pump 20 malfunctions, stops water supply, or the nozzle is blocked, the spray pressure disappears, the first spring resets, and the movable plate moves upward. The first electrode plate and the second electrode plate separate, the circuit is disconnected, and the photoelectric alarm immediately sounds, reminding the staff to stop the machine for maintenance.

[0036] The first electrode 1002 is electrically connected to the positive power electrode of the photoelectric alarm 22, and the second electrode 1004 is electrically connected to the negative power electrode of the photoelectric alarm 22.

[0037] A water tank 21 is installed on the rear end face of the cooling box 2, and a water pump 20 is installed on the upper end face of the water tank 21. The water pump 20 is connected to the high-pressure nozzle 9 through a water pipe.

[0038] The outer surface of the cylinder 16 is evenly provided with several air vents. The outer surface of the flow baffle 8 is fixedly connected to the inner wall of the cooling box 2. The lower end face of the rotating cover plate 402 is provided with an annular groove, and the inner side of the annular groove is provided with an internal thread. The upper end face of the cylinder 16 is provided with an annular plate, and the outer surface of the annular plate is provided with an external thread. The internal thread and the external thread are connected by a thread, so that the rotating cover plate 402 can be rotated off from above the adsorption cylinder 401.

[0039] The cleaning mechanism 19 includes a threaded rod 1903, with square plates 1901 arranged at both the front and rear of the threaded rod 1903. The square plates 1901 are fixedly connected to the inner wall of the housing 6. The outer surface of the threaded rod 1903 is fitted with threaded plates 1902. A connecting plate 1906 is installed on one side opposite to the two threaded plates 1902. A brush plate 1904 is installed on the lower end face of the connecting plate 1906. Multiple bristles 1905 are evenly installed on the lower end face of the brush plate 1904. A forward and reverse motor for rotating the threaded rod 1903 is installed on the rear end face of the square plate 1901. The operation of the forward and reverse motor can drive the threaded rod 1903 to rotate.

[0040] The exhaust pipe 17 is connected to the bottom surface of the rotating cover plate 402 through a third connecting pipe. The sealing mechanism 23 includes a fixing ring 2301. The outer surface of the fixing ring 2301 is fixedly connected to the inner wall of the exhaust pipe 17. A sealing plate 2302 is provided on the inner side of the fixing ring 2301. When the gas flows through the third connecting pipe, the gas can push open the sealing plate 2302.

[0041] A limiting ring 2303 is fitted behind the outer surface of the sealing plate 2302. The outer diameter of the limiting ring 2303 is larger than the hole diameter of the fixing ring 2301. A fixing plate 2305 is installed behind the inner wall of the exhaust pipe 17. A second spring 2304 is connected between the limiting ring 2303 and the fixing plate 2305. When the gas pushes the sealing plate 2302 open, it will compress the second spring 2304. The gas can be discharged from the gap between the sealing plate 2302 and the limiting ring 2303. When the machine stops, the second spring 2304 returns to its original position and the sealing plate 2302 closes.

[0042] When the odor adsorption and purification device in the hand sanitizer production process is in use, the power is turned on, and the exhaust gas is sent from the gas collection hood 1 into the cooling box 2 through the air pump 7. Multiple sets of staggered flow-blocking plates 8 are installed inside the cooling box 2, causing the exhaust gas to move upwards in an S-shape, prolonging the gas's residence time inside the box and improving cooling and washing effects. High-pressure nozzles 9 spray coolant downwards, cooling and dehumidifying the exhaust gas on one hand, and on the other hand, the sprayed liquid impacts the movable plate 1001, compressing the first spring 1003, keeping the first electrode plate 1002 and the second electrode plate 1004 in contact, thus completing the circuit and deactivating the photoelectric alarm 22. When the water pump 20 malfunctions, stops water supply, or the nozzle is clogged, the spray pressure disappears, the first spring 1003 resets, causing the movable plate 1001 to move upward, the first electrode plate 1002 separates from the second electrode plate 1004, the circuit is broken, and the photoelectric alarm 22 immediately sounds an alarm, reminding the staff to stop the machine for maintenance. The cooled exhaust gas enters the demister 3, where the spiral blades 12 driven by the motor 11 rotate, causing the gas to form a swirling flow. This causes the liquid in the gas to separate under centrifugal force. The swirling gas then impacts and reduces pressure under the combined action of the baffle plate 13 and the swirling plate 5. At a low flow rate, foam and droplets entrained in the exhaust gas are separated. The gas then enters the lower housing 6 and passes through the wire mesh demister 18 for fine filtration. A cleaning mechanism 19 is provided above the wire mesh demister 18. A forward and reverse motor drives a threaded rod 1903, which can move a brush plate 1904 back and forth along the surface of the wire mesh demister 18 to scrape away accumulated dirt and prevent clogging. The separated liquid is discharged through the drain mechanism 15 at the bottom. The clean gas after defoaming enters the adsorption device 4 and enters the adsorption cylinder 401 through the air vents on the surface of the cylinder 16. It is then filtered by adsorption materials such as activated carbon and molecular sieves. The material deeply removes odors and VOCs; the adsorbed gas pushes open the sealing plate 2302, compresses the second spring 2304, and is discharged from the exhaust pipe 17; when the machine stops, the second spring 2304 resets, the sealing plate 2302 closes to prevent waste gas backflow and odor backflow, and the cylinder 16 is threadedly connected to the rotating cover plate 402, which can be quickly disassembled and replaced with adsorption material, making maintenance convenient. This invention improves the purification and adsorption effect of waste gas through washing and cooling, three-stage defoaming, and adsorption, and by setting a gravity alarm mechanism 10, the impact force of the spray liquid is used to maintain the circuit path, ensuring the continuity and reliability of the treatment process.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
