Description

Technical Field

[0001] This application relates to the field of bell overflow water reuse technology, and specifically discloses an acetylene gas holder bell overflow water reuse device. Background Technology

[0002] The production of polyvinyl chloride (PVC) requires a large amount of acetylene and vinyl chloride gas as raw materials. These gases need to be stored in two bell-type gas holders: an acetylene gas holder with a bell and a vinyl chloride gas holder with a bell. Essentially, a bell-type gas holder is a retractable gas holder. The gas is located inside the holder. When filling, the bell moves upward, and the actual position of the bell indicates the gas filling volume. Similarly, when venting, the bell moves downward, and the actual position of the bell indicates the gas venting volume. Because it is a retractable gas holder, a water seal is required.

[0003] For details, please refer to Chinese Publication No. CN211035273U, which discloses a device for recycling overflow water from the bell jar of acetylene and vinyl chloride gas holders. The device includes a vinyl chloride gas holder and an acetylene gas holder, both composed of identical gas holder bodies, bell jars, guide sealing sleeves, and gas holder water tanks. The bell jar is located inside the gas holder body and moves up and down through the guide sealing sleeve below it while maintaining a seal. A gas holder water tank for liquid sealing is formed between the gas holder body and the bell jar. This device recycles overflow wastewater by setting up a wastewater collection pool on one side of the vinyl chloride and acetylene gas holders and connecting them to their respective overflow pipes via vinyl chloride and acetylene wastewater pipes. The overflow wastewater is then continuously replenished to the gas holder bell jar using a horizontal self-priming centrifugal pump. Excess wastewater is sent to an acetylene slurry concentration and sedimentation tank for recycling, significantly saving water resources, reducing water waste, and lowering the safety risks of the vinyl chloride and acetylene gas holders.

[0004] The above solution has the following shortcomings: During normal operation, when the gas inlet and outlet pipes are filled with gas, the bell jar will move upward. When the bell jar 102 moves upward, the guide sealing sleeve will squeeze the liquid seal water in the gas tank outward. The wastewater pipe will discharge the liquid seal overflow water to the wastewater collection tank for storage and recycling. When venting and releasing gas, the bell jar moves downward. Since the water that previously acted as the liquid seal is discharged from the overflow pipe, in order to ensure the effect of the liquid seal, the gas tank water tank will be replenished with water in a timely manner. The centrifugal pump will be started, and the liquid collected in the wastewater collection tank will be continuously replenished with water to the gas tank water tank through the water replenishment pipe.

[0005] The above-mentioned solutions still rely on pumps to recirculate water from the wastewater collection tank back into the gas holder water tank to achieve liquid sealing. While this approach is feasible, the entire supporting equipment and piping are too complex, and the bell itself is a large piece of equipment. The complexity of the entire supporting equipment and piping makes it difficult to arrange based on the bell. Therefore, this invention provides an acetylene gas holder bell overflow water recycling device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to solve the problem of complex structure in traditional gas holder bell overflow water recycling devices that use pumps and related structures.

[0007] To achieve the above objectives, the present invention provides the following basic solution: An acetylene gas holder bell jar overflow water recycling device includes an acetylene gas holder and a bell jar that is installed inside the acetylene gas holder and can slide inside the acetylene gas holder. It also includes an inlet and outlet pipe installed at the bottom of the acetylene gas holder, a water sealing plate installed on the outer periphery of the bell jar and in contact with the inner wall of the acetylene gas holder, a water inlet opened on the top of the acetylene gas holder, a water collection tank connected to the water inlet, a compressible water collection bag installed at the bottom of the water collection tank, and a squeezing component installed on the bell jar that can act on the compressible water collection bag. During air intake, the bell jar moves upward, and the squeezing component does not exert a squeezing effect on the compressible water collection bag; During venting, the bell jar moves downward, and the squeezing component squeezes and drains the compressible water collection bag.

[0008] Furthermore, the acetylene gas holder allows for the intake and exhaust of acetylene gas through intake and exhaust pipes, which in turn enables the bell to move upwards and downwards.

[0009] Furthermore, it also includes sealing water, which fills the sealing plate to prevent acetylene gas from leaking out.

[0010] Furthermore, the water collection tank includes an inner cavity wall, an outer cavity wall, and a chamber formed by the inner cavity wall and the outer cavity wall. The sealing water overflows and flows back into the chamber. The inner cavity wall is fixedly connected to the outer wall of the acetylene gas holder, and the inner cavity wall has connecting channels at the positions corresponding to the water inlet, the number and position of which correspond one-to-one with the water inlet. The connecting channels are connected to the water inlet.

[0011] Furthermore, the water inlet is arranged at an angle, and the water inlet is tilted towards the outside of the acetylene gas holder.

[0012] Furthermore, the opening of the compressible water-collecting bag is fixedly connected to the bottom of the inner cavity wall and the outer cavity wall, respectively, and the chamber is connected to the opening of the compressible water-collecting bag.

[0013] Furthermore, the extrusion assembly includes a connecting rod fixed to the bell jar and a pressure chamber fixed to the connecting rod for acting on the compressible water-collecting bag. The pressure chamber includes an outer plate, an inner plate, and a pressure chamber space formed by the outer plate and the inner plate. The outer plate and the inner plate are both arranged at an incline. The top of the pressure chamber space formed by the outer plate and the inner plate is a small space, and the bottom of the pressure chamber space formed by the outer plate and the inner plate is a large space.

[0014] Furthermore, when the exhaust is applied, the bell jar moves downward, and the top of the pressure chamber space formed by the outer and inner plates continuously squeezes the compressible water collection bag, causing the sealing water in the compressible water collection bag to overflow and flow back to the sealing plate.

[0015] Furthermore, it also includes a switch valve located at the bottom of the compressible water collection bag, the switch valve being connected to a wastewater pipe, and the free end of the wastewater pipe being connected to a wastewater pool.

[0016] The principle and effect of this solution are as follows: 1. Compared with existing technologies, this device simplifies the structure and reduces equipment complexity and manufacturing costs: Compared with traditional reuse devices that rely on pumps, valves, control modules, and complex pipelines to achieve overflow water transportation and reuse, this device only uses the linkage of a water collection tank, a compressible water collection bag, a squeezing component, and a bell to complete the squeezing drainage through the mechanical movement of the bell itself. This eliminates the need for core power components such as pumps and motors, as well as supporting control and protection structures, significantly reducing the number of equipment parts, simplifying the overall structural layout, reducing equipment manufacturing costs, and also reducing the difficulty of equipment installation. It is also more adaptable to the modification and new installation needs of existing acetylene gas holders, making it more versatile.

[0017] 2. Compared with existing technologies, this device does not require external energy such as electricity or mechanical energy throughout the entire process. It relies entirely on the natural lifting and lowering movement of the bell during the normal operation of the acetylene gas holder to drive the extrusion assembly to squeeze and drain the compressible water collection bag, realizing the reuse and recycling of overflow water. This fundamentally solves the energy consumption problem of traditional pump body reuse methods, achieving the goal of energy saving and consumption reduction. Long-term operation can significantly reduce the energy consumption cost of enterprise production, which is in line with the green and energy-saving production concept.

[0018] 3. Compared with existing technologies, this device accurately collects the overflow sealing water on the bell-shaped sealing plate through a water collection tank. After being stored in a compressible water collection bag and squeezed by the squeezing component, the sealing water is returned to the sealing plate for reuse, forming a closed-loop circulation system for sealing water. This effectively reduces the waste of sealing water, avoids water resource loss caused by the direct discharge of overflow water in traditional devices, and also reduces the amount of fresh sealing water to be replenished, thus lowering the water resource consumption cost in the production process.

[0019] 4. Compared with existing technologies, this device has a simple structure and no easily worn or high-failure-rate power components such as pumps and motors. Only simple components such as compressible water collection bags, extrusion components, and switching valves need to be inspected and maintained regularly, which greatly reduces the failure rate of the equipment and reduces the workload and maintenance costs of operation and maintenance personnel. At the same time, the design of the switching valve in conjunction with the wastewater pipe and wastewater pool can easily discharge the impurities and wastewater deposited in the compressible water collection bag, avoiding the accumulation of impurities from affecting the stability of the device operation, and further improving the ease of operation and maintenance of the device.

[0024] Implementation, for example Figures 1-6 As shown: An acetylene gas holder bell jar overflow water recycling device includes an acetylene gas holder 1 and a bell jar 3 that is installed inside the acetylene gas holder 1 and can slide inside the acetylene gas holder 1. It also includes an inlet / outlet pipe 2 installed at the bottom of the acetylene gas holder 1, a water sealing plate 4 installed on the outer periphery of the bell jar 3 and in contact with the inner wall of the acetylene gas holder 1, a water inlet 5 opened at the top of the acetylene gas holder 1, a water collection tank connected to the water inlet 5, a compressible water collection bag installed at the bottom of the water collection tank, and a squeezing component installed on the bell jar 3 that can act on the compressible water collection bag. During gas intake, the bell jar 3 moves upward, and the squeezing component does not squeeze the compressible water collection bag. During gas exhaust, the bell jar 3 moves downward, and the squeezing component squeezes and drains the compressible water collection bag. The acetylene gas holder 1 achieves acetylene gas intake and exhaust through the inlet / outlet pipe 2, and the intake and exhaust of acetylene gas achieve the upward and downward movement of the bell jar 3. The device also includes sealing water, which fills the water sealing plate 4 to prevent acetylene gas from overflowing.

[0025] The water collection tank includes an inner cavity wall 6, an outer cavity wall 9, and a chamber 8 formed by the inner cavity wall 6 and the outer cavity wall 9. The sealing water overflows and flows back into the chamber 8. The inner cavity wall 6 is fixedly connected to the outer wall of the acetylene gas holder 1, and the inner cavity wall 6 has connecting channels 7 at the positions corresponding to the water inlet 5. The number and position of the connecting channels 7 are one-to-one with the water inlet 5. The connecting channels 7 are connected to the water inlet 5, and the sealing water overflows and flows back into the chamber 8 through the connecting channels 7. In order to smoothly realize the sealing water overflow and flows back into the chamber 8, the water inlet 5 is arranged at an angle, and the water inlet 5 is tilted towards the outside of the acetylene gas holder 1.

[0026] The opening of the compressible water collection bag is fixedly connected to the bottom of the inner cavity wall 6 and the outer cavity wall 9, respectively. The chamber 8 is connected to the opening of the compressible water collection bag, thereby enabling sealed water to enter the compressible water collection bag.

[0027] The extrusion assembly includes a connecting rod 13 fixed to the bell jar 3 and a pressure chamber 14 fixed to the connecting rod 13 for acting on the compressible water collection bag.

The top of the pressure chamber space 1402 formed by the outer plate 1401 and the inner plate 1403 is a small space, and the bottom of the pressure chamber space 1402 formed by the outer plate 1401 and the inner plate 1403 is a large space.

[0028] When the exhaust is applied, the bell jar 3 moves down, and the top of the pressure chamber space 1402 formed by the outer plate 1401 and the inner plate 1403 continuously squeezes the compressible water collection bag, causing the sealing water in the compressible water collection bag to overflow and flow back to the sealing plate 4.

[0029] When inflated, the bell jar 3 moves upward, and the bottom of the pressure chamber space 1402 formed by the outer plate 1401 and the inner plate 1403 is a large space that will not squeeze the compressible water collection bag, thus achieving the sealing and allowing water to fall into the compressible water collection bag.

[0030] It also includes a switch valve 10 located at the bottom of the compressible water collection bag. The switch valve 10 is connected to a wastewater pipe 11, and the free end of the wastewater pipe 11 is connected to a wastewater pool 12. When the whole system needs to drain water, the switch valve 10 at the bottom of the compressible water collection bag is opened to achieve the complete recovery of the sealed water.

[0031] When water needs to be added, it is done manually by climbing onto the acetylene gas holder 1.

[0032] This device solves the problem of complex structure in traditional gas holder bell 3 overflow water recycling devices that use pumps and related structures.
