Description

Technical Field

[0001] This utility model relates to a purification device, and more particularly to a coke oven gas crude purification, oil removal, and naphthalene removal adsorbent. Background Technology

[0002] In existing technologies, coke oven gas can generally be used as a power fuel for ships, reducing pollutant emissions compared to traditional fuel oil. Coke oven gas mainly consists of combustible gases such as hydrogen and methane, and is a primary energy source for power fuel. However, coke oven gas also contains carbon monoxide, carbon dioxide, nitrogen, oxygen, and other hydrocarbon gases, and inevitably contains impurities such as oil and naphthalene. During ship navigation, if these impurities are not effectively removed, they will, on the one hand, reduce the combustion efficiency of coke oven gas, affecting the stability of the ship's power output; on the other hand, oil and naphthalene easily adhere and deposit on ship gas pipelines, combustion equipment, and other components, causing pipeline blockages and equipment corrosion, increasing the risk of equipment failure during ship navigation, and seriously threatening the safety of ship navigation and the lives and property of crew members. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, traditional coarse purification methods mainly include physical adsorption and chemical absorption. However, these methods often suffer from low efficiency, high cost, and complex operation, especially in oil and naphthalene removal, where existing technologies struggle to simultaneously meet the requirements of high-efficiency purification and low cost. Furthermore, existing purification equipment is difficult to maintain. Therefore, this invention provides a coke oven gas coarse purification oil and naphthalene removal adsorber.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A coke oven gas coarse purification, oil removal, and naphthalene removal adsorber includes a shell, a door panel hinged to the front end of the shell, an air inlet pipe at the upper end of the shell, a purification device installed inside the shell near the lower side of the air inlet pipe, an air outlet pipe at the lower end of the shell, and a naphthalene removal device installed inside the shell near the upper side of the air outlet pipe.

[0006] Compared with the prior art, the adsorber of this application is equipped with a purification device and a naphthalene removal device inside the shell, which can effectively remove impurities such as oil and naphthalene in coke oven gas, reduce the adhesion and deposition of these impurities on components such as ship gas transmission pipelines and combustion equipment, reduce the risk of pipeline blockage and equipment corrosion, thereby ensuring the normal operation of ship gas transmission and combustion systems and improving the reliability and service life of equipment.

[0007] As a further improvement of this utility model, the purification device includes a support frame, which is fixedly connected to the inner wall of the housing. An installation groove is provided in the support frame, and a filter screen is installed in the installation groove. The filter screen performs preliminary filtration of large particulate impurities and some oil droplets in the gas, intercepting the more obvious impurities in the gas, reducing the burden on subsequent purification steps, and improving the efficiency of the entire purification process.

[0008] As a further improvement of this utility model, a plurality of threaded holes are provided on the bottom surface of the mounting groove. The threaded holes correspond to the mesh holes of the filter screen. After assembly, the fixing bolts pass through the mesh holes and are threadedly connected to the threaded holes. Users can disassemble the filter screen through the fixing bolts to facilitate cleaning impurities on the filter screen.

[0009] As a further improvement of this utility model, the naphthalene removal device includes a placement frame, which is fixedly connected to the inner wall of the housing. The placement frame is provided with a plurality of placement slots, and activated carbon is installed in the plurality of placement slots. The activated carbon has a highly developed pore structure and strong adsorption performance, which can effectively adsorb naphthalene organic impurities in coal gas, thereby achieving efficient naphthalene removal and improving the purity of coal gas.

[0010] As a further improvement of this utility model, the inner walls of several of the placement slots are provided with baffles, and the activated carbon is located at the lower end of the baffles. When the coal gas passes through the naphthalene removal device, the baffles can block and disperse the airflow to a certain extent, allowing the airflow to pass through the activated carbon more evenly, improving the adsorption efficiency of the activated carbon for naphthalene in the coal gas, and making the naphthalene removal process more complete and stable.

[0011] As a further improvement of this utility model, the placement frame is located directly below the support frame, and the distance between the top of the shell and the support frame is equal to the distance between the bottom of the shell and the placement frame. This helps to form a more uniform airflow distribution of the gas within the adsorber. After preliminary filtration by the purification device, the gas can enter the naphthalene removal device with a relatively stable flow rate and direction, which is beneficial to improving the naphthalene removal effect.

[0012] As a further improvement of this utility model, a flow regulating device is installed on the outer wall of the air inlet pipe. The flow regulating device includes a sleeve, which is fitted onto the outer wall of the air inlet pipe. A rotating rod is rotatably connected to the outer wall of the sleeve. A handle is fixedly connected to one end of the rotating rod, and a regulating valve plate is fixedly connected to the other end. After assembly, the regulating valve plate is located inside the air inlet pipe. During the gas transportation process, rotating the handle drives the regulating valve plate at one end of the rotating rod to rotate, thereby controlling the gas flow rate. This allows for flexible adjustment of the flow rate according to the supply of coke oven gas, ensuring that the purification and naphthalene removal processes in the adsorber are carried out under suitable airflow conditions, thus improving the impurity removal efficiency.

[0013] As a further improvement of this utility model, a pressure relief valve is installed on one side of the housing. A sealing gasket is provided on the inner side of the door panel, and the sealing gasket is made of rubber material.

[0014] The beneficial effects of this invention are as follows: This invention incorporates a purification device and a naphthalene removal device within the casing, effectively removing impurities such as oil and naphthalene from coke oven gas. This reduces the adhesion and deposition of these impurities on components such as ship gas transmission pipelines and combustion equipment, thereby ensuring the normal operation of the ship's gas transmission and combustion systems. Furthermore, the filter screen is detachably mounted on the support frame. After initially filtering large particulate impurities and some oil droplets from the gas, the filter screen can be removed for cleaning and maintenance, thus ensuring the overall performance of the adsorber.

The filter screen 43 can perform preliminary filtration of large particulate impurities and some oil droplets in the gas, intercepting the more obvious impurities in the gas, reducing the burden on subsequent purification steps, and improving the efficiency of the entire purification process.

[0025] As a further improvement of this utility model, a plurality of threaded holes 44 are provided on the bottom surface of the mounting groove 42. The threaded holes 44 correspond to the mesh holes of the filter screen plate 43. After assembly, the fixing bolts 45 pass through the mesh holes and are threadedly connected to the threaded holes 44. The structure is simple and easy to install and disassemble.

[0026] As a further improvement of this utility model, the naphthalene removal device 6 includes a placement frame 61, which is fixedly connected to the inner wall of the housing 1. Specifically, the contact surface between the placement frame 61 and the housing 1 is coated with structural adhesive. The placement frame 61 is provided with a plurality of placement grooves 62, and activated carbon 63 is installed in the plurality of placement grooves 62. The activated carbon 63 has a highly developed pore structure and strong adsorption performance, which can effectively adsorb naphthalene organic impurities in coal gas, thereby achieving efficient naphthalene removal and improving the purity of coal gas.

[0027] As a further improvement of this utility model, the inner walls of several of the placement slots 62 are provided with baffles, which can be grid-type or honeycomb-type structures, and the activated carbon 63 is located at the lower end of the baffles. In this embodiment, when the gas passes through the naphthalene removal device, the baffles can block and disperse the gas flow to a certain extent, allowing the gas flow to pass through the activated carbon more evenly, improving the adsorption efficiency of the activated carbon for naphthalene in the gas, and making the naphthalene removal process more complete and stable.

[0028] As a further improvement of this utility model, the placement frame 61 is located directly below the support frame 41, and the distance H1 between the top of the shell 1 and the support frame 41 is equal to the distance H3 between the bottom of the shell 1 and the placement frame 61. This helps the gas to form a more uniform airflow distribution in the adsorber. Specifically, the distance H2 between the placement frame 61 and the support frame 41 is equal to the distance H1 between the top of the shell 1 and the support frame 41. After the gas is initially filtered by the purification device 4, it can enter the naphthalene removal device 6 with a relatively stable flow rate and direction, which is beneficial to improving the naphthalene removal effect.

A handle 73 is fixedly connected to one end of the rotating rod 72, and a regulating valve plate 74 is fixedly connected to the other end. After assembly, the regulating valve plate 74 is located inside the air inlet pipe 3. In use, the gas is transported to the housing 1 through the air inlet pipe 3. During the gas transport process, rotating the handle 73 drives the regulating valve plate 74 at one end of the rotating rod 72 to rotate, thereby controlling the gas flow rate. The flow rate can be flexibly adjusted according to the supply of coke oven gas, ensuring that the purification and naphthalene removal processes in the adsorber are carried out under suitable airflow conditions, thereby improving the impurity removal efficiency.

[0030] As a further improvement of this utility model, a pressure relief valve 11 is installed on one side of the housing 1. The pressure relief valve 11 is existing technology and will release pressure when the internal pressure of the housing 1 is too high, thereby improving safety.

[0031] As a further improvement of this utility model, a sealing gasket 21 is provided on the inner side of the door panel 2. The sealing gasket 21 is made of rubber material.
