Description
Technical field
The invention belongs to fire arrester fields, and in particular to a kind of enhanced heat exchange fire arrester.
Background technique
Nowadays, people are increasing to the degree of dependence of petrochemicals, and oil gas has been substituted coal as China
Main energy sources.Since natural gas transports and the catastrophic failure of people life property loss is caused to see repeatly not in storing process
Fresh, this transports and stores aspect to combustion gas and proposes very high requirement.
Fire arrester is that one kind can prevent flame in equipment, the device of pipeline enclosure spreading and propagation, by fire arrester shell, back-fire relief
Core and attachment composition, it can prevent natural gas and transport and the explosion accident in storing process.Currently, the type of fire arrester compared with
It is more, it is divided into explosion arrestment combustion type fire arrester and explosion arrestment Hong type fire arrester by flame propagation velocity.Explosion arrestment combustion type fire arrester can be prevented with Asia
The explosive flame that velocity of sound is propagated passes through, and explosion arrestment Hong type fire arrester can prevent the explosion propagated characterized by shock wave, with supersonic speed
Flame passes through.A kind of outstanding industrial fire arrester can handle high velocity deflagration flame and detonation flame bring well
It threatens, so that flame propagation be prevented to cause bigger disaster into other inflammable and explosive equipment, guarantees the people and country
Life and property safety.
The working principle of general tradition fire arrester are as follows: if will become after flame passes through many thin channels of fire-retardant core
Tiny flame is done, cooling heat exchange is carried out after the conduit wall contact of these tiny flames and fire-retardant core, drops to flame temperature
Below ignition point, to prevent propagation of flame.And preventing propagation of flame by the fire-retardant core in fire arrester merely is to be difficult to reach
To thorough extinguishing effect.
Summary of the invention
In order to solve the above-mentioned technical problem, the present invention is based on the progress of this viewpoint of the heat transfer effect in fire arrester working principle
The optimization design of fire arrester.It is computed discovery, when considering fire arrester wall surface heat convection, and giving wall surface heat transfer coefficient,
Slit Flame extinguishing efficiency has certain promotion.Based on " a kind of enhanced heat exchange fire arrester " of this design, before fire arrester shell
Temperature sensor and fin are set on wall, the outer wall surface of fire arrester housing rear is provided with shut-off valve at two, when temperature passes
Sensor detection does not occur deflagration flame, and combustible gas can be normal through pipeline；When detecting deflagration flame occur, the detonation of high temperature is fiery
Flame carries out cooling heat exchange three times by fin, fire-retardant core and with water, so that thorough extinguishing, reaches and save the energy, protection equipment
The purpose of safety.
The purpose of the present invention is a kind of enhanced heat exchange fire arrester, including admission line, two pairs of flange groups, fire arrester shell,
Outlet pipe, fire-retardant core, temperature sensor and steam-water pipe.
The fire arrester shell includes fire arrester housing front wall and fire arrester housing rear two parts, and admission line passes through the
One flange group connects fire arrester housing front wall, and fire arrester housing rear connects outlet pipe, fire arrester shell by second flange group
Fire-retardant core is installed, and fire arrester housing front wall and housing rear are solid by fire arrester flange between body antetheca and housing rear
It is fixed；This is to clean fire-retardant core for the ease of installation and removal.
The housing rear is made of fire arrester housing exterior walls and fire arrester inner walls, the fire arrester housing exterior walls and
Carbonated drink inner cavity is constituted between fire arrester inner walls；Store a certain amount of water in advance in carbonated drink inner cavity.
The surface of the fire arrester housing exterior walls is equipped with the first shut-off valve and the second shut-off valve, and the first shut-off valve and the
Two shut-off valves constitute steam-water pipe by carbonated drink exchange pipe connection, the first shut-off valve, the second shut-off valve and carbonated drink exchange pipe.
The temperature sensor is set on the entry position outer wall of fire arrester housing front wall.
The fire arrester shell is in trumpet type or cylindrical type.
The preset temperature of the temperature sensor is the adiabatic combustion temperature of combustible gas.
The fire-retardant core are as follows: metal mesh type, corrugated plate type or porous type, preferably corrugated plate type.
It is additionally provided with fin in fire arrester housing front wall outer surface, fin is paved with entire antetheca outer surface.
The fin are as follows: ring rib, needle rib or straight rib；It is higher that the temperature when being easy to appear deflagration flame is arranged in preferred pin rib
Region, spininess rib was arranged to increase surface coefficient of heat transfer, fire arrester housing front wall finite surface area to greatest extent in needle rib
It will affect the mating connection of flange group, certain amount can be set according to the actual situation.The selection of needle rib will thin as far as possible and its material
The thermal coefficient of matter is the bigger the better, to guarantee there is biggish surface coefficient of heat transfer.
The material of the fin is copper alloy.
A kind of working method of enhanced heat exchange fire arrester, when temperature sensor detection does not occur deflagration flame, the first cut-off
Valve and the second shut-off valve are in close state；When temperature sensor detects deflagration flame occur, the first shut-off valve is first opened, so
After be then turned on the second shut-off valve, so that a part of water being stored in advance in carbonated drink inner cavity and fire arrester inner walls is carried out hot friendship
It changes, water becomes to rise after vapor through the discharge of the first shut-off valve, then becomes water, In by carbonated drink exchange pipe and external environment heat exchange
Enter the second shut-off valve under the driving of pressure in carbonated drink exchange pipe, thus completes circulation, make by also still being deposited after fire-retardant core
Part high temperature deflagration flame by third time cooling heat exchange, thus thorough extinguishing.
The invention has the benefit that
When enhanced heat exchange fire arrester of the present invention detects deflagration flame occur, the deflagration flame of high temperature passes through rib
Piece, fire-retardant core and cooling three times is carried out with water exchange heat, thus thorough extinguishing, reach the mesh saved the energy, protect equipment safety
