Description
Technical field
The invention belongs to fire-proof and explosion-proof experiment air distributing device field, be specifically related to a kind of inflammable gas air distributing device.
Background technology
Inflammable gas is hazardous chemical common in industrial processes, and it generally adopts the mode such as closed container or pipeline to carry out accumulating.Due to the restriction in space, gas often produces rate of pressure rise sharply and higher explosion pressure after lighting a fire with air or other combustion-supporting property gas and vapor permeation under constraint condition, cause serious damage sequence.Datonation-inhibition technology is the effective means suppressed blast when exploding and front or blast generation may occurring.At present, existing datonation-inhibition technical research direction mainly comprises pressed powder explosion-suppressing material, inert gas explosion-suppressing material and water base explosion-suppressing material etc.Wherein inflammable gas or the preparation of inert gas have important effect to the progress of experiment and result.
The gas distributing system in domestic many fire-proof and explosion-proof laboratories generally mixes the formations such as unit, test flume unit, mechanical pressure gauge, data acquisition unit, computing machine primarily of gas source unit, flow controlling unit, gas.Flow controlling unit mostly adopts artificial reading to control, and what gas was mixed directly allocates test flume into from gas source unit, and more advanced then being mixed after device mixes by gas adds test flume.The shortcoming of above prior art is that labor workload is large, and number of work is many, distribution accuracy rate and success ratio low, affect greatly by peopleware, poor stability, precision is low, reaction velocity is slow, cause distribution and conventional efficient low.Most of air distributing device function singleness can only be that the experiment of same type uses; More complicated gas distributing system is then expensive, and precision preparation and accuracy have exceeded needed for experiment.
Summary of the invention
The present invention is directed to current datonation-inhibition experiment air distributing device function singleness, complicated operation loaded down with trivial details, be suitable for the technical matterss such as experiment type is limited, a kind of combustible gas air distributing device is provided, this device has the features such as cost is low, simple to operate, distribution is stable, convenient for cleaning, is applicable to polytype datonation-inhibition experiment.
Technical solution of the present invention: a kind of combustible gas air distributing device, comprising: mixed gas tank, seal flange, accessories section; Described mixed gas tank is by the interconnective horizontal cylindrical tank of bolt, and two ends adopt seal flange sealing.Described accessories section, comprises pressure vacuum gauge adapter, vacuum valve adapter, atmospheric valve adapter, gas outlet adapter, adapter for subsequent use is all arranged on mixed gas tank tank body top; The side that bottom is provided with the mixed gas tank of base for supporting is provided with gas inlet adapter, and opposite side is provided with gas outlet adapter.Described adapter for subsequent use (5) seals with plug.
Compared with prior art, the invention has the beneficial effects as follows: system architecture is reasonable, powerful, easy to operate.Distribution tank, seal flange are bolted, and distribution can realize different dismounting combination flexibly, so can experimentally needed for be assembled into the air distributing device of different structure and volume.Device adopts a point platen press distribution, accurately can regulate distribution ratio, and then can enter datonation-inhibition test to the flammable mixed gas of variable concentrations level.The setting of pressure vacuum gauge both can to have measured in distribution process vacuum tightness in distribution tank, can to measure again after distribution original pressure in distribution tank.Security of the present invention is high, low cost of manufacture, can be widely used in the distribution work of dissimilar datonation-inhibition experiment, reduces the spending of experiment.

Embodiment
below in conjunction with accompanying drawing and specific embodiment, the present invention is described in further detail, but not as the restriction to the technical scheme that the present invention relates to.
embodiment 1:
A kind of combustible gas air distributing device, comprising: mixed gas tank, tank body seal flange, annex adapter; Wherein said mixed gas tank is the horizontal cylindrical tank of a long 568mm, internal diameter 150mm, its two ends adopt seal flange sealing, pressure vacuum gauge adapter, vacuum valve adapter, atmospheric valve adapter, adapter for subsequent use are established in tank body top, tank body side is provided with gas inlet adapter, tank body opposite side is provided with gas outlet adapter, and each adapter internal diameter is 18mm, long 35mm, mutually equidistant between adapter, and adopt with annex and be threaded.
A kind of air distributing method (for methane air premix) of combustible gas air distributing device, the method comprises the steps:
(1) according to the required methane gas dividing potential drop that point platen press is calculated.If explosive container 9L, required methane concentration is 9.5%, and mixed gas tank 1L, then calculating desired gas stagnation pressure by a point platen press is 0.12MPa, and methane gas dividing potential drop is 0.12MPa.
(2) other valves except vacuum valve are closed, start vacuum pump to vacuumize mixed gas tank, note in pumping process observing vacuum pressure meter reading on mixed gas tank, when reading reaches-0.1MPa, close vacuum pump and vacuum valve; Then open methane gas admission valve, pass into the methane gas of 0.12MPa, then close methane gas admission valve, leave standstill a period of time.After experiment terminates, open atmospheric valve and gas inlet valve, pass into pressurized air, experimental gas remaining in system is purged.
embodiment 2:
(3) Fig. 2 is a kind of array mode of air distributing device of the present invention, and this array mode can make air distributing device volume increasing described in embodiment 1 be twice, and its implementation is: two identical mixed gas
