Description
Technical field
The utility model is related to exhaust gas treatment device, more particularly to spark arrester.
Background technology
Spark arrester is typically mounted in the pipeline of transporting combustible gases, or in the groove tank of ventilation, prevents propagating flame（It is quick-fried
Combustion or detonation）The device passed through, is made up of fire-retardant core, spark arrester shell and annex.It is for preventing inflammable gas and inflammable liquid
The safety device of the propagation of flame of body steam.Just it has been employed in the oil industry early in nineteen twenty-eight spark arrester, later and extensively
With in mine, colliery, water transport and chemical industry.In the oil industry, spark arrester is widely used in oil and oil production
On the storage tank of product.When the oil tank for storing oils runs into naked light or thunderbolt, so that it may fire hazard.In order to prevent this
Plant dangerous generation and use spark arrester.Spark arrester is also commonly used on the pipeline of conveying inflammable gas.If inflammable gas is drawn
Combustion, gas flame will travel to whole pipe network.In order to prevent this dangerous generation, spark arrester is also used.Spark arrester
It can use on the pipeline for having naked light equipment, to prevent back-fire trouble.But it can not prevent the open inflammable gas burnt and
The naked light burning of liquid.On the operation principle of spark arrester, mainly there are two kinds of viewpoints:One is to be based on heat transfer effect;One is to be based on
Wall effect.Heat transfer effect：One of necessary condition required for burning seeks to reach certain temperature, i.e. ignition point.It is less than
Ignition point, burning will stop.According to this principle, as long as the temperature of combustible substance is dropped to below its ignition point, so that it may with
Prevent spreading for flame.It will become some tiny flames after many thin channel of the flame by back-fire relief element.Design
During back-fire relief element inside spark arrester, then expand the contact area of tiny flame and conduit wall as far as possible, augmentation of heat transfer makes flame
Temperature is dropped to below ignition point, so as to prevent propagation of flame.Wall effect：Burning and blast are not intermolecular direct reaction,
But excited by extraneous energy, molecular link is destroyed, and produces anakmetomeres, and anakmetomeres are split into short life but very again
Active free radical, free radical bumps against with other molecules, generates new product, is further continued for and it while also producing new free radical
Its molecule reacts.When the combustible gas of burning is by the slype of back-fire relief element, the collision of free radical and conduit wall is several
Rate increases, and the free radical for participating in reaction is reduced.When the passage of spark arrester is too narrow to a certain degree, the collision of free radical and conduit wall
Occupy an leading position, because free radical quantity is drastically reduced, reaction can not proceed, namely combustion reaction can not pass through spark arrester
Continue to propagate.
Chinese utility model application CN201320243878.9 discloses exhaust pearl type spark arrester, including two pieces of spark arresters
Dividing plate, spark arrester framework and spark arrester baffle plate, the spark arrester framework are U-shaped framework, and the spark arrester baffle plate is fixed on back-fire relief
Rectangular frame is constituted at the opening of device framework, two pieces of spark arrester dividing plates are separately mounted to the front and rear open-mouth of rectangular frame,
Two pieces of spark arrester dividing plates, spark arrester framework and spark arrester baffle plate constitute storage pearl chamber, and the storage pearl intracavitary is filled with some spark arresters
Some through holes are uniformly offered on steel ball, two pieces of spark arrester dividing plates.But either traditional flame arrester structure or the row
Gas type spark arrester, their valve element resistance is all larger, more than 0.1MPa, causes ventilation to have some setbacks, heat-transfer effect is also undesirable, resistance
Fiery ability is weaker.
Utility model content
The technical problems to be solved in the utility model is that existing spark arrester ventilation is not smooth, and heat-transfer effect is also undesirable, resistance
Fiery ability is weaker, and a kind of low pass atmidometer type spark arrester is provided for this.
The technical solution of the utility model is：Low pass atmidometer type spark arrester, it includes open rectangular housing and laterally passed through
The fiery passage of row of open rectangular housing is through at, the fiery passage of the row is located at open rectangular housing central area and is fitted with steel wire,
The fiery passage of the row is located at the open end regions of rectangular housing two and is fitted with rectangular block, and the rectangular block is arranged along the axial direction of
Some through holes, the through hole internal clearance is combined with steel ball, and the open rectangular housing top side detachable formula is connected with top cover.
Rectangular block described in such scheme is connected with the fiery passage neck of row.
Top cover described in such scheme is affixed by bolt and open rectangular housing.
Steel wire described in such scheme is stainless steel.
The internal diameter that fiery passage is arranged described in such scheme is 15mm.
The beneficial effects of the utility model are the steel balls for making flame first pass through rectangular block, and flame is prevented based on wall effect
Propagating, then be based on heat transfer effect by steel wire reduces flame burning-point, effectively improves back-fire relief effect, and aeration resistance is small, structure
Simply, it is easy to disassemble.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram；
In figure, 1, open rectangular housing, 2, steel wire, 3, rectangular block, 4, steel ball, 5, top cover.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Lead to as shown in figure 1, the utility model includes open rectangular housing 1 with the row's fire extended transversely through in open rectangular housing
Road, the fiery passage of the row is located at open rectangular housing central area and is fitted with steel wire 2, and the fiery passage of the row is located at open rectangle
The end regions of housing two are fitted with rectangular block 3, and the rectangular block is arranged along the axial direction of some through holes, the through hole internal clearance
Steel ball 4 is combined with, the open rectangular housing top side detachable formula is connected with top cover 5.
One substantially rectangular back-fire relief region of steel wire formation, some tiny fire are divided into based on heat transfer effect by flame
The contact area of flame, increase flame and steel wire, to reduce the ignition point of flame.Steel ball in rectangular block can lead to flame
The path crossed narrows, and the collision based on wall effect free radical and conduit wall is occupied an leading position, because free radical quantity drastically subtracts
Few, reaction can not proceed, namely combustion reaction can not continue to propagate by spark arrester.
Traditional cylinder is changed to open rectangular housing plus dismountable top cover, preferably rectangular block by the utility model
It is connected with the fiery passage neck of row, it is easy to disassemble to safeguard, clear up carbon distribution.Steel wire is stainless steel, and top cover is by bolt with opening
Mouth rectangular housing is affixed, and the internal diameter of the fiery passage of row is 15mm, so adds spark arrester ventilation caliber, makes spark arrester aeration resistance
Drop to below 0.1Mpa.
