Description

Technical Field

[0001] This utility model belongs to the technical field of desulfurization equipment, specifically referring to a ship exhaust gas desulfurization treatment device. Background Technology

[0002] Ships are a general term for all kinds of vessels. Ships are means of transportation that can navigate or anchor in waterways for transport or operations. The main power source of ships is the combustion of diesel fuel. When ships burn diesel fuel, a large amount of exhaust gas is generated. The exhaust gas contains a large amount of harmful gases such as sulfur and nitrate. If these gases are directly emitted into the air, they will cause air pollution. Therefore, a marine diesel engine exhaust gas treatment device is needed to treat the exhaust gas.

[0003] However, existing ship exhaust gas desulfurization treatment devices are complex and bulky, and use a spray contact method, resulting in poor contact effect and low desulfurization efficiency. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model proposes a ship exhaust gas desulfurization treatment device, which effectively solves the problems of complex equipment, large size, poor contact effect and low desulfurization efficiency of ship exhaust gas desulfurization treatment devices, which adopt the spray contact method.

[0005] The technical solution adopted by this utility model is as follows: The present utility model proposes a ship exhaust gas desulfurization treatment device, including a circulating water tank, an inlet pipe, an outlet pipe and a desulfurization structure. The inlet pipe is installed through the lower side of the circulating water tank, the outlet pipe is installed through the upper side of the circulating water tank, and the desulfurization structure is installed on the circulating water tank. The desulfurization structure includes a spraying unit and a reagent addition unit. The spraying unit is installed inside the circulating water tank, and the reagent addition unit is installed above the circulating water tank.

[0006] The spray unit includes a desulfurization tower, a limiting seat, a packing layer, a drain pipe, a series pipe, an air inlet pipe, a fixed base, a high-pressure pump, a high-pressure water pipe, a six-way connector, a diverter pipe, spray heads, a water extraction pipe, and an exhaust pipe. The desulfurization tower is fixedly installed above the circulating water tank. The limiting seat is fixedly installed inside the desulfurization tower. The packing layer is supported above the limiting seat. The drain pipe is fixedly installed at the bottom of the desulfurization tower, with its bottom inserted into the bottom of the circulating water tank. The upper end of the series pipe is connected to the top of the desulfurization tower, and the other end is connected to the bottom of the second set of desulfurization towers. The air inlet pipe penetrates the circulating water tank. The pool is connected to the bottom of the first set of desulfurization towers. The fixed base is fixed to the bottom of the circulating water pool. The high-pressure pump is fixed on the fixed base. The high-pressure water pipe is vertically connected above the drain outlet of the high-pressure pump. The six-way connector is connected to the upper end of the high-pressure water pipe. One end of the diversion pipe is connected to the six-way connector and the other end is fixedly installed through the top of the desulfurization tower. The spray head is connected to the rear end of the diversion pipe and located inside the desulfurization tower. One end of the pumping pipe is connected to the suction port of the high-pressure pump and the other end is connected to the bottom of the circulating water pool. The exhaust pipe is connected to the top of the last set of desulfurization towers.

[0007] Preferably, the agent addition unit includes a metering pump and a dosing pipe. The metering pump is fixedly installed above the circulating water tank, and one end of the dosing pipe is connected to the discharge port of the metering pump and the other end is connected to the upper side wall of the circulating water tank.

[0008] To achieve better and more efficient desulfurization, five sets of series pipes are set up to connect the six desulfurization towers end to end, and the desulfurization towers are arranged in a circular ring.

[0009] To achieve the purpose of spraying more quickly, the spray head is set perpendicular to the filler layer and the spray head is located above the filler layer, which is made of a special ceramic material.

[0010] Furthermore, the circulating water tank is arranged in a cylindrical shape with an opening at the top.

[0011] To prevent air leakage, the bottom of the drain pipe is submerged in the bottom of the clean water in the circulating water tank.

[0012] The beneficial effects of this utility model using the above structure are as follows: The ship exhaust gas desulfurization treatment device proposed in this solution connects six sets of desulfurization towers in series through a series pipe, so that the ship exhaust gas can fully contact and react with the desulfurization solution in the limiting seat inside the desulfurization tower. The six sets of continuous desulfurization result in good desulfurization effect. Attached Figure Description

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes a ship exhaust gas desulfurization treatment device, which includes a circulating water tank 1, an inlet pipe 2, an outlet pipe 3, and a desulfurization structure 4. The inlet pipe 2 is installed through the lower side of the circulating water tank 1, and the circulating water tank 1 is arranged in the shape of a cylinder with an opening at the top. The outlet pipe 3 is installed through the upper side of the circulating water tank 1. The desulfurization structure 4 is installed on the circulating water tank 1. The desulfurization structure 4 includes a spray unit 5 and a reagent addition unit 6. The spray unit 5 is installed inside the circulating water tank 1, and the reagent addition unit 6 is installed above the circulating water tank 1.

[0021] The spray unit 5 includes a desulfurization tower 7, a limiting seat 8, a packing layer 9, a drain pipe 10, a series pipe 11, an air inlet pipe 12, a fixed seat 13, a high-pressure pump 14, a high-pressure water pipe 15, a six-way connector 16, a diversion pipe 17, a spray head 18, a water extraction pipe 19, and an exhaust pipe 20. The desulfurization tower 7 is fixedly installed above the circulating water tank 1, and the desulfurization towers 7 are arranged in a circular ring. The limiting seat 8 is fixedly installed inside the desulfurization tower 7, and the packing layer 9 is supported above the limiting seat 8. The packing layer 9 is made of a special ceramic material. The drain pipe 10 is fixedly installed at the bottom of the desulfurization tower 7, and the bottom of the drain pipe 10 is inserted into the bottom of the circulating water tank 1, with the bottom end of the drain pipe 10 submerged in the bottom of the clear water in the circulating water tank 1. The upper end of the series pipe 11 is connected to the top of the desulfurization tower 7, and the other end is connected to the bottom of the second set of desulfurization towers 7. The series pipe 11 is configured with five... The six desulfurization towers 7 are connected in series. The air inlet pipe 12 passes through the circulating water pool 1 and is connected to the bottom of the first desulfurization tower 7. The fixed base 13 is fixed to the bottom of the circulating water pool 1. The high-pressure pump 14 is fixed on the fixed base 13. The high-pressure water pipe 15 is vertically connected above the drain port of the high-pressure pump 14. The six-way connector 16 is connected to the upper end of the high-pressure water pipe 15. One end of the diversion pipe 17 is connected to the six-way connector 16 and the other end passes through the top of the desulfurization tower 7 and is fixed. The spray head 18 is connected to the rear end of the diversion pipe 17 and is located inside the desulfurization tower 7. The spray direction of the spray head 18 is perpendicular to the packing layer 9 and the spray head 18 is located above the packing layer 9. One end of the water pump 19 is connected to the suction port of the high-pressure pump 14 and the other end is connected to the bottom of the circulating water pool 1. The exhaust pipe 20 is connected to the top of the last desulfurization tower 7.

[0022] like Figure 1 and Figure 3 As shown, the reagent addition unit 6 includes a metering pump 21 and a dosing pipe 22. The metering pump 21 is fixedly installed above the circulating water tank 1, and one end of the dosing pipe 22 is connected to the discharge port of the metering pump 21 and the other end is connected to the upper side wall of the circulating water tank 1.

[0023] In practical use, clean water is first injected into the circulating water tank 1 through the drain pipe 3. Then, the metering pump 21 is controlled to draw desulfurization agent from the agent tank and discharge it into the circulating water tank 1 through the dosing pipe 22 to mix with the clean water. Then, the air inlet pipe 12 is connected to the ship's exhaust outlet, and the high-pressure pump 14 is started to draw desulfurization liquid from the circulating water tank 1 through the water suction pipe 19. The liquid is then diverted into the diversion pipe 17 through the six-way connector 16 on the high-pressure water pipe 15 and sprayed downwards through the spray nozzle 18. At this time, the desulfurization liquid is sprayed onto the packing layer 9. Meanwhile, the ship's exhaust gas enters the bottom of the first agent addition unit 6 and is discharged upwards. At this time, the ship's exhaust gas passes through the packing. Layer 9 is thoroughly mixed with the desulfurization solution, causing the sulfur oxides in the exhaust gas to react chemically with the alkaline substances in the desulfurization solution, generating substances such as sulfates. These substances are discharged through the drain pipe 10 to the bottom of the circulating water tank 1 for settling. The ship exhaust gas flows continuously through six sets of desulfurization towers 7 through the series pipe 11, thus achieving complete reaction and avoiding residue. Finally, the clean ship exhaust gas is discharged from the exhaust pipe 20 above the last set of desulfurization towers 7. After a certain period of time, a large amount of sediment remains at the bottom of the circulating water tank 1. The inlet pipe 2 is then opened for discharge and cleaning, and the clean water in the circulating water tank 1 is replaced. The above is the entire process of using the ship exhaust gas desulfurization treatment device.
