Abstract
The present invention relates to a petrochemical bunker with uniform ventilation. The present invention is provided with a bunker body, wherein the lower end of the bunker body is provided with a cone section, the tip end of the cone section is provided with a discharge opening, the upper edge of the cone section is provided with an annular wind belt pipe, and one side of the latter is provided with a first-circuit main wind pipe; a plurality of reverse blowing wind nozzles are uniformly arranged along the annular wind belt pipe, and the upper part of the bunker body is provided with a feeding opening and an air outlet. The present invention is characterized in that a second-circuit main wind pipe is arranged on the cone surface of the same side of the first-circuit main wind pipe, and an annular wind belt pipe is arranged along the cone section; the second-circuit main wind pipe is communicated with the wind belt pipe, a plurality of second-circuit reverse blowing wind nozzles are also uniformly arranged on the cone surface, and the baffle plates of the second-circuit reverse blowing wind nozzles, at the lower parts of the second-circuit reverse blowing wind nozzles, are arranged in the cone section and are parallel to the cone surface; the discharge opening is communicated with the second-circuit main wind pipe by a reverse blowing wind pipe. The bunker body of the present invention has uniform ventilation, and can improve the degassing efficiency of the bunker. The defects of the existing bunker that ventilation is uneven, combustible gas existing in dead zones can not be discharged from the air outlet, the air concentration of part cone in the bunker is too high, etc. are overcome. Thereby, the safety of the bunker is improved.
Description
Technical field
The present invention relates to the feed bin that a kind of petrochemical complex is used, particularly relate to a kind of petrochemical industry feed bin of Uniform Ventilation.
Background technology
Feed bin is used widely in multiple industry such as mining, chemical industry, food and agricultural, harbour, and the feed bin accident is very common in countries in the world, and has caused the tremendous economic loss.With regard to petroleum chemical industry, the static blast accident takes place in high pressure polyethylene feed bin often, and one of key factor that causes this accident of generation is that local ethylene concentration is too high in the storehouse.Existing high pressure polyethylene feed bin has warehouse, there is cone segments the lower end of this warehouse, there is discharging opening at this cone segments tip, this cone segments upper limb is equipped with an annular wind band pipe, the latter's a side has one road air main, along a plurality of blowback wind tuyeres that distribute uniformly in this annular wind band pipe, an anti-L shaped reverse-blow pipe is arranged between discharging opening and one road air main, discharging opening is communicated with one road air main by this anti-L shaped reverse-blow pipe, inlet point and air extractor duct are arranged at warehouse top, when feed bin feed time weak point, when material level is in cone segments (being tuyere lower edge on the blowback wind), because top blowback wind tuyere draught area is greater than the air main area, and anti-L shaped reverse-blow pipe is also drawn with top blowback tuyere UNICOM from air main and is made it be difficult to set up back pressure, can't play draught effect, forms degassing dead band at conical section, cause this zone ethylene gas concentration to exceed safety control scope (0.5%wt), make the minimum ignition energy (MIE of dust in the storehouse
H) the value reduction, the mouth tubular stinger of being in the wind easily produces under the heap surface creeping discharge situation of spark discharge and material quick-fried the catching fire of sudden strain of a muscle that easily causes material with the heap face.
Summary of the invention
The petrochemical industry feed bin that the purpose of this invention is to provide a kind of Uniform Ventilation, it can overcome the above-mentioned defective of existing feed bin, can make feed bin cone portion Uniform Ventilation, and fire gases is got rid of from the feed bin air extractor duct.
A kind of petrochemical industry feed bin of Uniform Ventilation, one warehouse is arranged, there is cone segments the lower end of this warehouse, there is discharging opening at this cone segments tip, this cone segments upper limb is equipped with an annular wind band pipe, the latter's a side has one road air main, along a plurality of blowback wind tuyeres that distribute uniformly in the annular wind band pipe, inlet point and air extractor duct are arranged at warehouse top, it is characterized in that on the conical surface of the same side of one road air main, two road air mains being housed, around cone segments one annular wind band pipe is arranged, two road air mains are communicated with wind band pipe, a plurality of two tunnel blowback wind tuyeres also are housed on the above-mentioned conical surface uniformly, are equipped with the two tunnel blowback wind tuyere baffle plates parallel with the conical surface in the bottom of two tunnel blowback wind tuyeres in cone segments inside, discharging opening is communicated with two road air mains by reverse-blow pipe.
Advantage of the present invention is the warehouse Uniform Ventilation, especially distribution of gas is more even on the feed bin cone portion cross-sectional plane, avoid the blow of wind in the storehouse, fire gases is discharged from air extractor duct, thereby improve the degassing efficiency of feed bin effectively, and when a transportation work style breaks down, can keep the operation of feed bin by the air quantity that strengthens another transportation work style.Overcome ventilate in the existing feed bin inhomogeneous, have defectives such as dead band, fire gases can not be discharged from air extractor duct, storehouse inner cone local gas excessive concentration, the safety that has improved feed bin is a feed bin a kind of brand new, Uniform Ventilation, safety.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Feed bin of the present invention has a warehouse 1, there is cone segments the lower end of this warehouse 1, there is discharging opening 2 at this cone segments tip, this cone segments upper limb is equipped with an annular wind band pipe 4, the latter's a side has one road air main 3, along 12 the blowback wind tuyeres 5 that distribute uniformly in the annular wind band pipe 4, inlet point 11 and air extractor duct 12 are arranged at warehouse 1 top, it is characterized in that on the conical surface of the same side of one road air main 3, two road air mains 6 being housed, around cone segments one annular wind band pipe 7 is arranged, two road air mains 6 are communicated with wind band pipe 7,6 two tunnel blowback wind tuyeres 8 also are housed on the above-mentioned conical surface uniformly, be equipped with the two tunnel blowback wind tuyere baffle plates 9 parallel with the conical surface in cone segments inside in the bottom of two tunnel blowback wind tuyeres 8, discharging opening 2 is communicated with two road air mains 6 by anti-L shaped reverse-blow pipe 10.
When using feed bin of the present invention, this feed bin inlet point 11 links to each other with on-the-spot feeding line, discharging opening 2 links to each other with on-the-spot discharging pipeline, one road air main 3 links to each other with on-the-spot one road main air pipeline, two road air mains 6 link to each other with on-the-spot two road main air pipelines, material enters feed bin from inlet point 11, go out from discharging opening 2, blowback wind enters feed bin by one road air main 3 through annular wind band pipe 4 and 12 coupled blowback wind tuyeres 5, another road blowback wind is by two road air mains, the 6 annular wind band pipe 7 of process and 6 coupled blowback wind tuyeres 8, and entering feed bin through anti-L shaped reverse-blow pipe 10, fire gases is got rid of by air extractor duct 12.The effect one of two tunnel blowback wind tuyere baffle plates 9 is to avoid material to enter tuyere, the 2nd, and it is more even that blowback wind is distributed.
