Description
Technical field
The utility model relates to gas cleaning plant, particularly a kind ofly fluoridizes two sulphur pyrolysis installations for ten of the negative product of sulfur hexafluoride production process.
Background technology
Existingly fluoridize the pyrolysis installation of two sulphur pyrolysis for ten, as shown in Figure 1.Ten chemical formulas of fluoridizing two sulphur are S
2F
10, be the dimer of sulfur pentafluoride, be effumability liquid at normal temperatures and pressures, colourless, odorless, tasteless, chemically stabilizer pole.In water and high alkali liquid, decompose extremely slow and be insoluble to wherein, generate SF but in the time of 200 ℃ to 300 ℃, decompose fully
4And SF
6S
2F
10Be a kind of extremely toxic substance, white mouse caused death in eight hours when containing 1ppm in the air.The product standard of sulfur hexafluoride just has biologic test project (with small white mouse as subjects), mainly detects and whether contains ten in the sulfur hexafluoride product and fluoridize two sulphur.Existing pyrolysis installation is mainly the stainless steel tube of a φ 325, the carbon steel pipe of a φ 159 of liner, and a thermometer boss is put at the carbon steel pipe top of φ 159, a material inlet, a material outlet, stainless steel tube outer lining heater, and be incubated, prevent thermal loss, see Fig. 1 for details.There is following defective in this method:
1, maintenance rate is high.Because enter in the medium of pyrolysis tower and fluoridize Er Liu ﹑ sulfur hexafluoride and other subfluoride except ten; also have fluorine gas, the character of fluorine gas is very active, can react with stainless steel helices and pyrolysis inner wall of tower; especially at high temperature this reaction is violent especially, has more residue to generate.These residues are more and more, will stop up gas circuit in the short time, cause production to carry out, and about two months will stop and carry out block clearing.
2, operating cost is high, carries out block clearing because about two months will stop, so produce start-stop car frequency height, causes operating cost to improve.
The utility model content
The purpose of this utility model is in order to provide a kind of cost of investment low, technology controlling and process smoothly and operating cost low ten fluoridize two sulphur pyrolysis installations.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model provides a kind of ten and fluoridizes two sulphur pyrolysis installations, comprise cylindrical bodies, described cylindrical bodies internal sleeve is provided with carbon steel pipe, the top of cylindrical bodies is provided with media outlet, the carbon steel pipe upper end laterally is provided with the medium import, and the carbon steel pipe top is provided with thermometer boss; Described carbon steel pipe bottom is connected with the ash groove, and described ash groove is provided with cleaning door.
Wherein, described cleaning door comprises cleaning door and lower deashing hole; The horizontal level of described upper cleaning door is higher than described lower deashing hole.
Wherein, described cleaning door is arranged at the sidewall of ash groove.
Further, described ash groove is square structure.
Further, described ash groove, upper cleaning door, lower deashing hole are carbon steel material.
The beneficial effects of the utility model are:
Be different from traditional ten and fluoridize two sulphur pyrolysis installations, the technical program arranges the ash groove in described pyrolysis installation bottom, and at the ash groove cleaning door is set.The technical program has a plurality of advantages:
1, cost of investment is low, and the making of ash groove and installation price are about 0.4 ten thousand yuan, but the economic benefit that it brings is to have reduced by twice start-stop car.
2, maintenance rate is low, because increase the ash groove, although also there is residue to generate, stops up the time lengthening of gas circuit, and the cycle stretch-out to six month of block clearing is carried out in parking.
Description of drawings
Figure 1 shows that the positive view of existing pyrolysis tower;
Figure 2 shows that the front elevational view of pyrolysis tower described in the utility model.
Label declaration:
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, below in conjunction with embodiment and cooperate that accompanying drawing is detailed to give explanation.
See also Fig. 1 and Fig. 2, present embodiment provides a kind of ten fluoridizes two sulphur pyrolysis installations, comprise cylindrical bodies, be arranged with carbon steel pipe 2 in the cylindrical bodies, the top of described cylindrical bodies is provided with media outlet 4, the carbon steel pipe upper end laterally is provided with medium import 1, and the carbon steel pipe top is provided with thermometer boss 3; Described carbon steel pipe 2 bottoms are connected with ash groove 7, and described ash groove 7 is provided with cleaning door.
Described ten to fluoridize the operation principle of two sulphur pyrolysis installations as described below: after gas enters from medium import 1, the carbon steel pipe of flowing through moves downwards, described gas at last from the carbon steel pipe bottom out, by the space upwards walking of carbon steel pipe bottom gas out from cylindrical bodies and carbon steel pipe interval, flow out from media outlet at last, form a U-shaped process of circulation.Be in the gas of carbon steel pipe bottom residue since action of gravitation can fall in the described ash groove.
The technical program adopts the technique of brand-new underlying ash groove 7, because increase ash groove 7, although also there is residue to generate, stops up the time lengthening of gas circuit, and the cycle stretch-out to six month of block clearing is carried out in parking.So overcome the shortcoming that maintenance rate in the past is high, operating cost is high, thereby had the advantage that cost of investment is low, maintenance rate is low, operating cost is low.
In certain improved technical scheme, described cleaning door is arranged at the sidewall of ash groove 7, and described cleaning door comprises cleaning door 6 and lower deashing hole 5; The horizontal level of described upper cleaning door 6 is higher than described lower deashing hole 5, shown in concrete the consulted Fig. 2 of the plan of establishment of cleaning door, because the residue of ash groove the inside not only can be deposited to the bottom, but also can stick to the sidewall of ash groove, therefore need to respectively be provided with cleaning door in top and the bottom of ash groove, when the cleaning residue, could remove the residue of ash groove the inside clean.Described ash groove 7 can be arranged to various shape, and wherein square structure is preferred technical scheme, increases described ash groove 7, make the block clearing of to stop in original two months, can extend to 6 months now, prolong greatly the start-stop car cycle, bring good economic benefit.
Further improving in the technical scheme, described ash groove 7, upper cleaning door 6, lower deashing hole 5 are carbon steel material.Fluorine gas has the effect of passivation to carbon steel material, forms layer protecting film on the surface of carbon steel, stops the further corrosion of fluorine gas to carbon steel material, prolongs the replacement cycle of carbon steel equipment.
The operation principle of pyrolysis installation described in the utility model is exactly to increase an ash groove 7 in the bottom of pyrolysis tower, respectively there is a cleaning door top and bottom of ash groove 7, owing to increased ash groove 7, the block clearing of originally will stopping in two months, can extend to 6 months now, prolong greatly the start-stop car cycle, brought preferably economic benefit.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
