Description

Technical Field

[0001] The present invention relates to the technical field of exhaust gas treatment, and in particular to an activated carbon-based ship exhaust gas treatment device. Background Art

[0002] Ships produce exhaust gas when they are sailing. The exhaust gas of ships is mainly composed of the following pollutants: sulfur dioxide, nitrogen oxides and particulate matter. During the operation of the ship, it will have an impact on the environment and human health. Therefore, a treatment device is needed to treat the exhaust gas before it is discharged. The ship exhaust gas treatment device is a device used to treat harmful gases emitted by ships to reduce the impact on the environment. The main goal of this equipment is to reduce the emission of harmful substances in the ship's exhaust gas.

[0003] A Chinese patent provides a ship exhaust treatment device with publication number CN221492048U, which includes a treatment box, a ventilation pipe fixedly provided on the upper end of the treatment box, a purification box fixedly provided on one side of the ventilation pipe, a dust removal box fixedly provided on one side of the treatment box, and two storage boxes fixedly provided in the middle position inside the treatment box.

[0004] The above device uses a processing box, a purification box and a dust removal box to treat exhaust gas. The harmful substances in the exhaust gas are treated by physical treatment. The dust removal box is equipped with multiple layers of filter screens with different densities. Through layer-by-layer filtration, the particles in the exhaust gas are filtered and removed. The exhaust gas passes through two protective boxes filled with activated carbon particles, which can effectively adsorb and remove residual harmful substances in the exhaust gas. However, its pre-treatment structure is relatively simple. Since the exhaust temperature discharged by the ship engine is relatively high, in order to ensure the adsorption performance of the activated carbon, the exhaust temperature needs to be lowered to a suitable adsorption temperature range for the activated carbon. If the exhaust temperature is not treated, the adsorption effect may be affected. At the same time, it is difficult to monitor the concentration of pollutants such as sulfur dioxide and nitrogen oxides in the exhaust gas, and the exhaust gas is directly discharged, which has a poor effect. Moreover, the activated carbon will reach a saturated state after adsorbing a certain amount of pollutants and needs to be regenerated. The activated carbon is directly installed in the purification box, which is difficult to maintain and replace, and has low flexibility in use. Summary of the Invention

[0016] Beneficial effects of the present invention: The present invention arranges a dust removal pipe, a filter assembly, and an adsorption assembly to cooperate with each other.

[0017] By setting up an electric telescopic rod, a sealing plate, an activated carbon plate, and a sliding plate to cooperate with each other, the smoke dust after filtration and cooling can be adsorbed and filtered for a second time through the movable block to remove smaller particles. When in use, the pressure detection data at the pressure sensor can be used to adjust different movable blocks for alternating adsorption.

[0018] By setting up a stuffing pipe, a discharge pipe and a barrier net to cooperate with each other, the activated carbon particles with appropriate particle size can be transported to the space between the two movable blocks through the stuffing pipe, which is convenient for adding and improving the adsorption effect. The failed activated carbon can be discharged regularly through the discharge pipe, which is convenient for the collection and subsequent treatment of the activated carbon. After adding, the stuffing pipe can be connected to the emergency pipeline. In the event of a fault, the exhaust gas can be discharged to a safe place in an emergency to avoid the accumulation of exhaust gas on board.

[0019] By setting up a detection tube in conjunction with the adsorption component, the flue gas quality can be detected by setting a gas monitoring sensor during smoke adsorption. When the smoke is unqualified, the exhaust fan and the solenoid valve are closed, and air is blown into the detection tube through the air nozzle to blow the smoke toward the adsorption component again for adsorption, so as to increase the contact time between the activated carbon plate and the activated carbon particles in the discharge pipe and the smoke, so as to thoroughly adsorb and filter it until it is discharged from the solenoid valve after detection.

A rotating rod 308 is rotatably installed at the center of the front and rear ends of the coarse filter 306 and the fine filter 307, and a fan blade 309 is provided at the front position of the outer ring of the rotating rod 308; An adsorption assembly 6 is provided at the rear end of the dust removal pipe 1. The adsorption assembly 6 has a filling pipe and two mounting frames 601. The two mounting frames 601 are installed at the front and rear ends of the filling pipe, and the front end of one of the mounting frames 601 is connected to the rear end of the dust removal pipe 1. Two movable grooves are provided inside the mounting frame 601. Movable blocks 602 are slidably installed in the two movable grooves. An activated carbon plate 603 is installed inside the movable block 602 by fixing bolts. Two sealing boxes 605 are installed on the top of the mounting frame 601, and a sliding plate 604 is slidably installed inside the sealing box 605.

An electric telescopic rod 606 is installed at the front end of the sealing box 605, and the push rod end of the electric telescopic rod 606 is connected to the sliding plate 604.

[0024] As a technical optimization solution of the present invention, the front and rear ends of the installation frame 601 are both provided with a material change port 607 that is adaptively matched with the movable block 602 on the side away from the dust removal pipe 1, and the front and rear ends of the installation frame 601 are detachably installed with a sealing plate 608 that is adaptively matched with the material change port 607 through a fixing nut 609.

[0025] By controlling the push rod of the electric telescopic rod 606 to retract, the saturated activated carbon plate 603 can be moved to the material exchange port 607 for disassembly.

[0027] By opening the discharge valve on the discharge pipe 6012, the activated carbon particles saturated with adsorption in the filling pipe will leak out from the discharge pipe 6012 until they are emptied. The discharge pipe 6012 can be closed, and then the feed valve on the filling pipe 6011 can be opened. Subsequent personnel can add suitable and new activated carbon particles into the filling pipe.

[0028] As a technical optimization solution of the present invention, the rear end of one mounting frame 601 is connected to a detection tube 7, the rear end of the detection tube 7 is connected to a filter cotton box 9, the end of the filter cotton box 9 away from the detection tube 7 is connected to an exhaust fan 11, and the rear end of the exhaust fan 11 is connected to an exhaust pipe 12.

[0029] When the exhaust gas quality does not meet the emission standards, the exhaust fan 11 and the solenoid valve 13 will be closed to prevent the exhaust gas that does not meet the emission standards from being discharged. After the gas monitoring sensor 8 detects that the flue gas meets the emission standards, the solenoid valve 13 is controlled to open and the exhaust fan 11 is started to quickly discharge the treated flue gas.

[0030] As a technical optimization solution of the present invention, a solenoid valve 13 is provided at the connection between the exhaust fan 11 and the exhaust pipe 12, a gas monitoring sensor 8 is provided through the top of the detection tube 7, a nozzle pipe 10 is provided at the rear position of one side of the detection tube 7, and an end of the nozzle pipe 10 extending into the detection tube 7 is provided with a nozzle head that adapts to the activated carbon plate 603.

[0031] By connecting the air jet pipe 10 to the external air jet pipe and subsequently opening the air valve, clean air can be delivered to the detection tube 7 and sprayed out, so as to blow the smoke into the adsorption component 6 to assist the smoke to contact the adsorption component 6 and improve the adsorption efficiency.

[0032] As a technical optimization solution of the present invention, the sides of the two movable blocks 602 that are close to each other are fitted with the installation frame 601, and a sealing ring 6010 is provided at the connection between the installation frame 601 and the movable block 602. The activated carbon plate 603 is detachably connected to the movable block 602 by fixing bolts.

[0033] The sealing ring 6010 is provided to reduce the probability of exhaust gas leakage, and the activated carbon plate 603 and the movable block 602 are detachably connected to facilitate disassembly and replacement.

[0034] As a technical optimization solution of the present invention, the outer ring of the rotating rod 308 is fixedly connected to the front end of the coarse filter 306 and the fine filter 307 with a connecting plate 3010, and the two connecting plates 3010 are installed with a cleaning plate 3011 through connecting bolts, and the rear ends of the two cleaning plates 3011 are respectively fitted with the front end of the coarse filter 306 and the fine filter 307.

[0035] The coarse filter 306 and the fine filter 307 can intercept large impurities such as carbon soot particles and unburned fuel particles in the exhaust gas. The cleaning plate 3011 is attached to the coarse filter 306 and the fine filter 307 and rotates continuously to clean the windward surface, thereby reducing the probability of blockage by large impurities.

[0036] As a technical optimization solution of the present invention, the water-cooling circulation pipe 302 is a spiral hollow tube, and the inner walls of the dust removal pipe 1, the detection pipe 7, and the filling pipe are all provided with a ceramic coating.

[0037] The water-cooled circulation pipe 302 can reduce the exhaust gas temperature and make the exhaust gas temperature reach the optimal adsorption temperature range of activated carbon, thereby improving the adsorption effect. The spiral hollow pipe can improve the contact effect, and the ceramic coating can prevent friction between the exhaust gas and the pipe.

[0038] As a technical optimization solution of the present invention, a temperature sensor 4 is installed at the rear position of the top end of the dust removal pipe 1, and a pressure sensor 5 is installed at the rear position of the top end of the dust removal pipe 1 and the rear position of the bottom end of the detection tube 7.

[0039] The exhaust gas temperature and pressure can be monitored by the temperature sensor 4 and the pressure sensor 5, and different movable blocks 602 can be adjusted for alternate adsorption. The pressure sensor 5 can adopt a high-sensitivity sensor, such as PT124B-210 from Sensors Expert, and the temperature sensor 4 can adopt Pt100 from Rosemount.

[0040] As a technical optimization solution of the present invention, the connection between the filling tube and the discharge tube 6012 is conical, activated carbon particles are arranged in the filling tube, and a plurality of bulk material inclined plates 6014 are arranged inside the filling tube.

[0041] The provided bulking inclined plate 6014 can play a bulking role to prevent the activated carbon particles from piling up into agglomerates directly below the filling tube 6011, thereby improving the adsorption effect of the activated carbon particles.

[0042] When the present invention is in use, valves are installed on each pipeline, which will not be described in detail here. The dust removal pipe 1, the detection tube 7, the adsorption assembly 6, the filter assembly 3 and other components can be installed in a suitable processing position with the help of an existing bracket. Then, the air intake connecting pipe 2 can be connected to the ship's exhaust pipe to transport the exhaust gas into the dust removal pipe 1, and the liquid inlet 303 is connected to the ship's cooling water system, and the liquid outlet 304 is connected to the circulating water pump to circulate the cooling water flow into the water-cooling circulation pipe 302. After the exhaust gas enters the dust removal pipe 1, the exhaust gas in the dust removal pipe 1 can be cooled by the water-cooling circulation pipe 302, so that the exhaust gas temperature is controlled at the optimal adsorption temperature of the activated carbon; The flue gas will first come into contact with the coarse filter 306 and the fine filter 307, which intercept and filter large impurities such as soot particles and unburned fuel particles in the exhaust gas. The filtered and cooled exhaust gas will then come into contact with the activated carbon plate 603 to adsorb and filter small impurities and harmful gases in the exhaust gas. The exhaust gas will then pass through the first mounting frame 601 and come into contact with the activated carbon particles in the barrier net 6013 for secondary adsorption. During the adsorption process, the exhaust gas will enter the detection tube 7. Since the adsorption effect of activated carbon is proportional to the contact time, that is, the longer the contact time, the better the adsorption effect, the exhaust gas quality can be detected by the gas monitoring sensor 8. When the exhaust gas quality does not meet the emission standards, the exhaust fan 11 and the solenoid valve 13 will be closed to prevent the exhaust gas that does not meet the emission standards from being discharged. Until the gas monitoring sensor 8 detects that the flue gas meets the emission standard, the solenoid valve 13 is controlled to open and the exhaust fan 11 is started to quickly discharge the treated flue gas. This step can be repeated to adsorb the exhaust gas. If the exhaust gas does not meet the standard, the air jet pipe 10 can be connected to the external air jet pipe. Subsequently, by opening the air valve, clean air can be delivered to the detection tube 7 and sprayed out to blow the flue gas toward the adsorption component 6 to assist the flue gas in contacting the adsorption component 6 and improve the adsorption efficiency. When the exhaust gas is transported, the exhaust gas contacts the fan blades 309, which can drive the fan blades 309 to rotate continuously. Since the fan blades 309 are installed on the rotating rod 308, they can drive the rotating rod 308 to rotate. The rotation of the rotating rod 308 can drive the cleaning plate 3011 to rotate in contact with the coarse filter 306 and the fine filter 307, so as to clean their windward surfaces and reduce the probability of clogging by large particles of impurities. At the same time, two activated carbon plates 603 are installed in each of the two mounting frames 601 through a movable block 602, and a pressure sensor 5 is installed in the dust removal pipe 1. At this time, the pressure in the dust removal pipe 1 can be detected by the pressure sensor 5. When one of the activated carbon plates 603 gradually becomes saturated with adsorption, its resistance will gradually increase, and the pressure will also increase accordingly. When the pressure reaches the set alarm value, the push rod of one of the electric telescopic rods 606 can be controlled to retract to drive the saturated activated carbon plate 603 to move to the refueling port 607, and the push rod of the other electric telescopic rod 606 will be extended, so that a new activated carbon plate 603 can be pushed between the dust removal pipe 1 and the detection tube 7 to adsorb the exhaust gas; After that, the personnel can remove the sealing plate 608 with the help of tools, and then remove the saturated activated carbon plate 603 from the movable block 602 for replacement so as to automatically adjust. At the same time, the saturated activated carbon plate 603 can be moved to the maintenance position. The service life and adsorption efficiency of the activated carbon can also be evaluated based on the pressure change data measured at the pressure sensor 5. After the replacement, when the pressure sensor 5 detects that the pressure in the dust removal pipe 1 is still relatively high, the external collection pipe can be connected to the discharge pipe 6012, and then the discharge valve on the discharge pipe 6012 can be opened. At this time, the activated carbon particles saturated with adsorption in the filling pipe will leak out from the discharge pipe 6012 until they are emptied. The discharge pipe 6012 can be closed, and then the feed valve on the filling pipe 6011 can be opened. Subsequent personnel can add new activated carbon particles with appropriate particles into the filling pipe. During the adding process, the bulking inclined plate 6014 can be provided to play a bulking role to prevent the activated carbon particles from piling up into a mass just below the filling pipe 6011, so as to improve the adding uniformity. After the addition, the new activated carbon particles have less resistance and will not cause significant interference to the exhaust gas circulation. At this time, the pressure will drop accordingly. After the activated carbon particles are added, the filling pipe 6011 can be connected to the external emergency exhaust pipe. In the event of a fault or other emergency, the filling pipe 6011 can be manually opened to discharge the exhaust gas in the dust removal pipe 1 and the detection pipe 7 to a safe place to avoid the accumulation of exhaust gas on board and causing danger. Moreover, the display and control components and modules used in the above-mentioned electric telescopic rod 606, temperature sensor 4, pressure sensor 5, gas monitoring sensor 8, solenoid valve 13, and exhaust fan 11 are all existing technologies, which can be fully implemented by those skilled in the art. The provision of power is also common knowledge in this field. Needless to say, the content protected by the present invention does not involve improvements to software and control programs.

Obviously, many modifications and variations are possible based on the content of this specification.
