Embodiment Construction

[0026] A warship "invisible" chimney design, which consists of the following parts: 1 chimney exhaust channel, 2 exhaust fan with motor, 3 filter screen, 4 annular cooling pipe, 5 cooling liquid outlet of cooling pipe, 6 cooling liquid of cooling pipe Inlet, 7 outer wall heat insulation layer, 8 coolant flow direction, 9 other pipes of heat dissipation part, 10 exhaust gas flow direction in the chimney, 11 exhaust gas discharge direction, 12 hot coolant heat exchange device inside the warship.

[0027] The hot exhaust gas produced by the warship boiler is discharged from the warship through 1 chimney exhaust channel. The hot exhaust gas is discharged from the interior of the warship to the exterior of the warship.

[0028] The wall of the chimney is designed as a ring structure, and 4 ring cooling pipes are formed inside the ring, and the cooling liquid, such as cold water, enters the 4 ring cooling pipes through the cooling liquid inlet of the 6 cooling pipes, and the cold wat...

Abstract

The invention relates to a warship chimney. The requirement of naval armaments for invisibility is higher and higher, and the possibility that a warship is investigated is greatly increased due to thelarge size, thick black smoke and the too high temperature of the exposed surface part of a chimney. By the adoption of the warship chimney, a smoke filter, a heat insulation layer, an exhaust fan, awater circulation cooling structure and the like are additionally arranged, black smoke of the warship chimney and the volume of the chimney are reduced, and the temperature of the outer portion is lowered. Through a series of transformation, the probability that the warship is found in the navigation process is reduced, and the invisibility effect of the warship chimney can be improved to a certain limit.

Description

technical field [0001] The invention relates to a chimney for warships. By installing smoke filters, heat insulation layers, exhaust fans, and water circulation cooling, etc., the chimneys for warships can reduce black smoke and reduce the external temperature, thereby reducing the risk of being found by warships during navigation. probability. Background technique [0002] At present, there are three types of mainstream heat engine power plants for ships: boiler steam engine / steam turbine type, diesel type, and gas turbine type. [0003] The steam engine was the earliest naval power plant, and the steam turbine appeared a little later. Both of these engines need a boiler to work, and the combustion pressure of the furnace of the boiler is very low, so the chimney must be made taller. To ensure smooth exhaust. The higher the chimney, the greater the pressure difference between the upper and lower sides, and the easier it is to exhaust. [0004] Diesel engine power plant ...
