Description
Technical field
The utility model relates to industrial waste gas and administers field, refers to a kind of novel mixed gas tank on distributing instrument particularly.
Background technology
Iron and steel pollutant control is classified as one of important strategic task by Wuhan Iron and Steel Plant, and the investment of annual more than 10% is for improving environment-protecting integrated equipment, Wuhan Iron and Steel Plant green technology is through years development, waste water, controlling waste residue technology are day by day ripe, but the Treatment process of industrial waste gas is still had much room for improvement, Sintering Plant Wisco has 5 sintering machines, NOx in sintering tail gas, SO2 content is high, serious to atmosphere pollution, the method of wherein common process atmosphere pollution has low nitrogen burning+SCR denitration technique, NID dry method Novel desulfurizing dust removing integrated technique, ammonia desulfurizing process.For the steel mill of new upper sintering project, consider from the long term growth of environmental protection, steel mill should pay the utmost attention to combined desulfurization and denitration integrated technique, sintering exhaust gas component is complicated, sour corrosion gas and alkaline corrosion gas are also deposited, and constituent concentration difference is huge, for accurate analog sintering tail gas, need to use many gas circuits distributing instrument to carry out tail gas simulation, and require to export mist after distributing instrument, the principle of general distributing instrument is by multipath gas by after mass flowmenter accurate measurement, after mixed gas tank mixing, exports mist.
The distributing instrument that laboratory uses, mixed gas tank is just as a transition buffer device, its main purpose is buffer gas, prevent gas branch road local pressure excessive, when unstrpped gas kind is less, mixed gas tank successful, mist is more even, when unstrpped gas is of a great variety, and when physical property difference is larger, original mixed gas tank can not meet test needs.Such as, in sintering tail gas, containing SO
2, NO
x, H
2o, dust, concentration range is wide, and gas with various concentration can differ several order of magnitude, and cylinder outlet differing pressure is huge; Gas with various physical property difference is larger, different densities gas not easily fully mixes, original mixed gas tank can not meet completely laboratory sintering tail gas join even needs, and original mixed gas tank is full-closed structure, as the dust carried in unstrpped gas, very easily occur piling up, cause gas pipeline to block, affect the normal use of distributing instrument.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of novel mixed gas tank on distributing instrument.
For achieving the above object, the novel mixed gas tank on distributing instrument designed by the utility model, it is characterized in that: comprise tank body, it is characterized in that: described tank wall top is provided with high density gas air inlet pipe, described tank wall bottom is provided with low density gas air inlet pipe, below described low density gas air inlet pipe offside tank wall on offer mist escape pipe.
Further, the wire netting for particle in filtering gas is provided with in the middle part of described tank inner chamber, can ensure that the gas of different densities has enough blending spaces, and when gas with various is by wire netting, the particles such as the dust carried in gas can be suspended on wire netting, ensure that the pure of mist.
Further, described tank base has cinder-discharging port, when the dust on metal gathers more, can regularly clear up by unloading grey window.
Again further, described tank inner chamber sidewall circumferentially uniform intervals is provided with at least one circle projection, and cushion different storage pressure gas out, collaborating appears in the gas preventing pressure excessive, the phenomenon of backflow.
Further, described projection is provided with two circles, and wherein a circle is arranged on above high density gas air inlet pipe, and another circle is arranged between wire netting and low density gas air inlet pipe.
The utility model has the advantage of: an air inlet pipe is changed into high density gas air inlet pipe and low density gas air inlet pipe and mist escape pipe is located at bottom, utilize gravity principle, high density gas is transmitted from top to bottom, low density gas transmits from bottom to top, fully mixed point of mixed gas tank zone line, both avoided low density gas directly to export from mist escape pipe without mixing, in turn ensure that mixed Midst density gas directly can export from mist escape pipe; Wire netting, can ensure that the gas of different densities has enough blending spaces, and when gas with various is by wire netting, the particles such as the dust carried in gas can be suspended on wire netting, ensure that the pure of mist; Tank wall circumferentially uniform intervals is provided with several projections, and cushion different storage pressure gas out, collaborating appears in the gas preventing pressure excessive, the phenomenon of backflow; Its structure is simple, and low cost of manufacture is easy to use, is easy to promote.
Accompanying drawing explanation
Fig. 1 is the structural representation of the novel mixed gas tank on distributing instrument.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of novel mixed gas tank on distributing instrument shown in figure, comprise tank body 1, tank body 1 side wall upper part is provided with high density gas air inlet pipe 3, tank body 1 lower sidewall is provided with low density gas air inlet pipe 4, below low density gas air inlet pipe 4 offside tank body 1 sidewall on offer mist escape pipe 5, the wire netting 2 for particle in filtering gas is provided with in the middle part of tank body 1 inner chamber, cinder-discharging port 6 is had bottom tank body 1, tank body 1 intracavity sidewall circumferentially uniform intervals is provided with at least one circle protruding 7, protruding 7 are provided with two circles, wherein a circle is arranged on above high density gas air inlet pipe 3, another circle is arranged between wire netting 2 and low density gas air inlet pipe 4.
During use, gas larger for density is inputted tank body 1 by high density gas air inlet pipe 3, gas less for density is inputted tank body 1 by low density gas air inlet pipe 4 simultaneously, for the gases at high pressure in high density gas or low density gas, prior in the mixed gas tank of other species input, such gas is allowed to contact with several projections 7 in advance, reduce local pressure, when different types of gas mixes in tank body 1, ensure that gas flow is larger, and innocuous gas is in normally open, guarantee in time after mixing terminates, being purged by the dust that wire netting 2 hangs enters bottom tank body 1, guarantee in trimestral Inspection cycle, carry out unloading ash work, ensure mixed gas tank inner drying.
