Description

Technical Field

[0001] The utility model belongs to the technical field of ship design, and particularly relates to a ship smoke exhaust pipe cabin insulation system. Background Art

[0002] There are two commonly used methods for exhaust pipe through-cabin fittings: one is to coat the exhaust pipe with insulating material, and then set an outer sleeve outside the insulating material, set sealing plates at both ends of the outer sleeve to seal the insulating material, and set a through-cabin covering plate on the outer sleeve, which is welded to the hull wall plate; the other is to coat the exhaust pipe with insulating material, and then set an outer sleeve outside the insulating material, set sealing plates at both ends of the outer sleeve to seal the insulating material, set a covering plate type flange on the outer sleeve, and then set a mounting flange on the hull wall plate, and the covering plate flange is connected to the mounting flange with bolts.

[0003] Among them, the first method cannot prevent the high temperature in the exhaust pipe from being transmitted to the hull wall through the outer sleeve, thereby posing a safety hazard of scalding personnel; the second method does not meet the requirements of the fire penetration code.

[0004] Therefore, how to provide a ship exhaust pipe cabin insulation system that can make the exhaust pipe cabin parts meet the requirements of fire insulation, water tightness, air tightness, etc., and eliminate the safety hazard of personnel injury has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The embodiment of the utility model provides a ship exhaust pipe cabin insulation system, which can make the exhaust pipe cabin parts meet the requirements of fire insulation, water tightness, air tightness, etc., and eliminate the safety hazard of personnel injury.

[0006] In an embodiment of the utility model, a ship exhaust pipe cabin insulation system is provided, including: an exhaust pipe, a flange, a covering plate, an outer sleeve, a sealing plate, a coolant pump, a coolant inlet and outlet stop valve, a coolant outlet stop check valve and a temperature switch.

[0007] The outer sleeve is arranged outside the smoke exhaust pipe, and both ends of the outer sleeve are sealed by the sealing plate to form inner and outer tube cavities;

[0008] The coolant pump is used to provide coolant to the system, and the inner and outer tube cavities are filled with coolant;

[0009] Among them, the inlet of the coolant is downward and the outlet of the coolant is upward. When high-temperature exhaust gas passes through the smoke exhaust pipe, the wall temperature of the smoke exhaust pipe increases. When the coolant rises to the set temperature value of the temperature switch, the temperature switch sends a signal to start the coolant pump. The coolant pump injects coolant into the inner and outer tube cavities of the smoke exhaust pipe through the coolant inlet and outlet stop valves. The high-temperature coolant flows away from the coolant outlet, and the wall of the smoke exhaust pipe and the outer sleeve are cooled by the flowing cooling water.

[0010] Further, the system includes: a relief valve;

[0011] The discharge valve is used for maintenance and cleaning of the ship's exhaust pipe cabin insulation system.

[0012] Furthermore, the covering plate is connected to the outer casing for connection with the hull wall plate.

[0013] Furthermore, the coolant is a cooling medium including at least cooling water.

[0014] The beneficial effects brought by the utility model are as follows:

[0015] It can be seen from the above scheme that the embodiment of the utility model provides a ship exhaust pipe cabin insulation system, including: an exhaust pipe, a flange, a covering plate, an outer sleeve, a sealing plate, a coolant pump, a coolant inlet and outlet stop valve, a coolant outlet stop check valve and a temperature switch. The outer sleeve is arranged outside the exhaust pipe, and the two ends of the outer sleeve are sealed with the sealing plate to form an inner and outer tube cavity; the coolant pump is used to provide coolant to the system, and the inner and outer tube cavities are filled with coolant. The technical solution of the utility model can make the exhaust pipe cabin parts meet the requirements of fire insulation, watertightness, airtightness, etc., and eliminate the safety hazard of personnel injury. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 A schematic structural diagram of a ship smoke exhaust pipe cabin insulation system according to an embodiment of the utility model is shown. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] According to the existing exhaust pipe through-chamber arrangement, the high temperature of the exhaust gas in the exhaust pipe is isolated by insulating materials, but the high temperature will still be transmitted to the hull structure through the outer jacket, posing a safety hazard of scalding. However, the present design method can remove the temperature of the high-temperature exhaust gas through cooling water, thus solving the problem of the high-temperature exhaust gas in the exhaust pipe being transmitted to the hull structure and causing scalding.

[0019] like Figure 1 As shown, Figure 1 A schematic structural diagram of a ship smoke exhaust pipe cabin insulation system according to an embodiment of the utility model is shown.

[0020] In the figure, a ship exhaust pipe cabin insulation system includes: an exhaust pipe, a flange, a covering plate, an outer sleeve, a sealing plate, a coolant pump, a coolant inlet and outlet stop valve, a coolant outlet stop check valve and a temperature switch.

[0021] The outer sleeve is arranged outside the smoke exhaust pipe, and both ends of the outer sleeve are sealed by the sealing plate to form inner and outer tube cavities;

[0022] The coolant pump is used to provide coolant to the system, and the inner and outer tube cavities are filled with coolant;

[0023] Among them, the inlet of the coolant is downward and the outlet of the coolant is upward. When high-temperature exhaust gas passes through the smoke exhaust pipe, the wall temperature of the smoke exhaust pipe increases. When the coolant rises to the set temperature value of the temperature switch, the temperature switch sends a signal to start the coolant pump. The coolant pump injects coolant into the inner and outer tube cavities of the smoke exhaust pipe through the coolant inlet and outlet stop valves. The high-temperature coolant flows away from the coolant outlet, and the wall of the smoke exhaust pipe and the outer sleeve are cooled by the flowing cooling water.

[0024] In one embodiment of the utility model, the system comprises: a discharge valve;

[0025] The discharge valve is used for maintenance and cleaning of the ship's exhaust pipe cabin insulation system.

[0026] In another embodiment of the utility model, the covering plate is connected to the outer casing for connection with the hull wall plate.

[0027] In another embodiment of the present invention, the coolant is a cooling medium including at least cooling water.

[0028] It is understandable that in other implementations of the embodiments of the present invention, the type of the coolant can be adjusted as needed to enhance the cooling effect of the ship's exhaust pipe cabin insulation system.

[0029] In another embodiment of the utility model, a ship exhaust pipe cabin insulation system can make the exhaust pipe cabin parts meet the requirements of fire insulation, water tightness and air tightness, and eliminate the safety hazard of personal injury.

[0030] A ship exhaust pipe cabin insulation system comprises an exhaust pipe, a flange, a covering plate, an outer casing, a sealing plate, a cooling water pump, a cooling water inlet and outlet stop valve, a cooling water outlet stop check valve, a discharge valve, and a temperature switch.

[0031] An outer sleeve is arranged outside the exhaust pipe, and both ends of the outer sleeve are sealed with sealing plates to form inner and outer tube cavities of the exhaust pipe. Cooling water is filled between the inner and outer tube cavities, and cooling water is provided to the ship exhaust pipe insulation system through the provided cooling water pump. At the same time, a discharge valve is provided for maintenance and cleaning.

[0032] In the embodiment of the present invention, the exhaust pipe passage member needs to be installed horizontally, with the cooling water inlet facing downward and the cooling water outlet facing upward. When the high-temperature exhaust gas passes through the exhaust pipe, the temperature of the exhaust pipe wall continues to rise, and the high temperature transfer causes the temperature of the cooling medium to continue to rise. When the cooling medium rises to the set temperature value of the temperature switch, the temperature switch sends a signal to start the cooling water pump.

[0033] The cooling water pump injects cooling water into the inner and outer tube cavities of the smoke exhaust pipe, and the high-temperature cooling water flows away from the cooling water outlet. The flowing cooling water cools the smoke exhaust pipe wall and the outer sleeve, thereby achieving the purpose of heat insulation of the smoke exhaust pipe cabin parts.

[0034] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
