Abstract
The utility model discloses an air exhaust duct spark extinguishing device, which comprises a barrel (3), wherein an air inlet (2) is arranged in a lower end plate of the barrel (3); an upper end plate of the barrel (3) is provided with an air outlet (9); the barrel (3) is internally provided with a fire retarding cover (6) and a spiral plate group (7); the fire retarding cover (6) is sleeved at the lower end of the air outlet (9); the spiral plate group (7) is positioned between the air outlet (9) and the fire retarding cover (6); one end of the spiral plate group (7) is fixedly connected with an outer periphery of the lower end part of the air outlet (9); the other end of the spiral plate group (7) is fixedly connected with the inner periphery of the fire retarding cover (6); the barrel (3) is also internally provided with an ash exhaust hole (4); one end of the ash exhaust hole (4) penetrates through the barrel (3) and is positioned outside the barrel (3); and the other end of the ash exhaust hole (4) penetrates through the fire retarding cover (6) and is communicated with the fire retarding cover (6). Through the air exhaust duct spark extinguishing device provided by the utility model, sparks in the air exhaust duct can be thoroughly extinguished, and the possibility of fire disasters is avoided.
Description
Technical field
The utility model relates to a kind of exhaust duct spark extinguishing device.
Background technique
Along with process of industrialization constantly advances, the consumption of oil, rock gas constantly increases, due to region energy difference, these goods and materials need huge means of transportation to carry out the strange land contact, and the special boats such as crude oil carrier, product carrier and liquefied natural gas (LNG) carrier have therefore arisen at the historic moment.These boats and ships are for improving endurance and reducing operating cost, the most not high heavy oil of fuel oil grade that use of the fuel fired equipment such as diesel engine and boiler, thereby inevitably can be residual without clean-burning carbon particle in vent systems, be Mars, if Mars is along with air-flow enters atmosphere, in case drop onto the deck and touch oil gas or rock gas, will be that ship is ruined the people and died.So need to increase the measure of fire extinguishing star in vent systems.
Summary of the invention
In order to address the above problem, the utility model provides a kind of exhaust duct spark extinguishing device, can thoroughly extinguish Mars in exhaust duct, stops the possibility that fire occurs.
The utility model has adopted following technological scheme: a kind of exhaust duct spark extinguishing device, it comprises cylindrical shell, be provided with suction port on the lower end sheet of cylindrical shell, upper head plate is provided with the air outlet, be provided with fire-retardant cover and spiral plate group in cylindrical shell, described fire-retardant cover is enclosed within the lower end of air outlet, and described spiral plate group is between air outlet and fire-retardant cover, one end of spiral plate group is fixedly connected with the excircle of underpart, air outlet, and the other end is fixedly connected with the inner circumference of fire-retardant cover; Also be provided with ash output opening in described cylindrical shell, an end of described ash output opening passes the outside that cylindrical shell is positioned at cylindrical shell, and the other end penetrates in fire-retardant cover and fire-retardant cover UNICOM.
Described spiral plate group is comprised of some equally distributed spiral plates; The top of described cylindrical shell is provided with two hangers, and two hangers are symmetrical arranged; The outer surface of described cylindrical shell is provided with thermal-protective coating; Described cylindrical shell is provided with ash outlet.
the utlity model has following beneficial effect is: the utility model can be stopped the possibility that fire occurs to the full extent, fire-retardant cover conical surface and the spiral plate of streamline, stop the sufficient while, can guarantee the unobstructed of air-flow, effectively reduce the resistance that produces because stopping, after entering this device from the waste gas of fuel fired equipment air outlet, fully collide with fire-retardant cover bottom and male cone (strobilus masculinus), air-flow changes direction, after flowing through the cylindrical shell upper head plate, again collides with spiral plate cylinder inboard wall, the air-flow of process spiral plate is High Rotation Speed and flows, and produce collision with the fire-retardant cover inner conical surface, air-flow after collision is discharged from the air outlet through reflection, the Mars that is mingled with in air-flow is fully extinguished after above-mentioned three collisions, after the utility model long-play, cigarette ash can be cumulative, need to regularly clear up, and regularly opens ash outlet and ash output opening, the cigarette ash that falls at fire-retardant cover and cylinder body bottom can be cleaned out, because the delivery temperature of diesel engine is quite high, the staff operates and is easy to because of carelessness cause scald, so laid thermal-protective coating one outside cylindrical shell, can guarantee that surface temperature of the present utility model is lower than 60 degree, for ease of lifting of the present utility model, in the upper head plate left and right sides of cylindrical shell, two hangers have been installed respectively.
