Abstract
The utility model discloses a desorption tower for a sulfuric acid manufacturing system, which comprises a tower body made of PVC sheets, wherein a manhole is formed on the tower body, a gas inlet hole is formed at the lower part on the left side of the tower body, a gas outlet hole is formed at the upper part of the tower body, a layer of wire mesh of which the thickness is 316L, the wire diameter is 0.23mm and the resistance value is 490Pa is arranged in the middle of the tower body. A spray device is arranged at the upper part of the wire mesh and connected with a washing pipeline. The desorption tower provided by the utility model can temporarily replace an electric dust precipitator to dedust and purify when the electric dust precipitator can't operate normally, or aid in further dedusting and purifying when the electric dust precipitator operates normally, so as to reduce the consumption of the electric dust precipitator; and moreover, the utility model has the advantages of low cost, convenient maintenance, easy cleaning, and obvious dedusting effect.
Description
Affiliated technical field
The utility model relates to a kind of desorption tower of sulfuric acid manufacturing system.
Background technology
Cottrell is the visual plant of flue gas acid preparing system dust removing workshop section.Can it normally move the clean-up effect that directly has influence on furnace gas.Cottrell mainly is made of exhausting system, dust-precipitating system and ash-transmission system.At the section of cottrell, flue gas is from wherein passing through corona electrode insulation against ground, heavy dirt electrode grounding.When in addition during high direct voltage, set up electric field between the two poles of the earth between corona electrode and heavy dirt electrode, because corona electrode diameter and radius of curvature are little, and heavy dirt electrode curvature radius is big, so near the electric-field intensity corona electrode is bigger.If voltage is greater than the corona critical voltage between two electrodes, then gas generation ionization, form the corona zone, in gas, produce electronics, cation and anion, and under electric field action, move to two electrodes, the charged dust of flue gas suspended particles by electric field is moving to heavy dirt Ghandler motion, and is deposited on dirt and extremely goes up.Advantages such as cottrell has the efficiency of dust collection height, can handle higher temperature and bigger cigarette content, fluid impedance losses is little during through dust arrester, power consumption is little.But there is following defective in it:
1, install a cover cottrell at least units up to a million, cost is higher.
When 2, using in the early stage, owing to process Installation and operating personnel are unfamiliar with reasons such as equipment, it is continuous to cause cottrell to stop stopping out fault
3, the repair and maintenance of cottrell bothers very much.
Summary of the invention
The desorption tower of the sulfuric acid manufacturing system that the utility model provides when being used for cottrell and can't running well, temporarily substitutes the effect that cottrell plays udst separation; Perhaps when cottrell turns round, help further udst separation, reduce the consumption of cottrell; Cost is low, and repair and maintenance is cleared up easily easily, and dust removing effects is obvious.
In order to achieve the above object, the tower body of the utility model agent set for making of the PVC plate is provided with manhole on tower body, and bottom, tower body left side is provided with the gas feed hole, and tower body top is provided with gas outlet hole, at the tower body middle part layer of metal silk screen is set; Woven wire top is provided with spray equipment, and spray equipment connects flushing pipe.
Wherein oven wire mesh blanket is 316L, and the silk footpath is 0.23mm, and Resistance Value is 490Pa.
There is following advantage in this device:
1, cost is low.Silk screen mist eliminator of fabrication and installation only needs about 20,000 yuan.Its cost is significantly less than cottrell.
2, easy repair and maintenance.One cover silk screen can use more than 2 years, changed several thousand yuan on a cover silk screen, and operating cost also greatly reduces.
3, cleaning easily.After finding that the mist eliminator resistance rises to certain value, open flushing pipe flushing a few minutes to get final product.
4, dust removing effects is obvious.This device is arranged on the inter cooler front, moves after organizing dust, has alleviated the work load of inter cooler greatly, even if there is not electric cleaner, inter cooler can not stop up yet, and operate as normal is continuously always discharged the requirement that all is up to state standards of gas dustiness and acid mist index.
Description of drawings
Accompanying drawing is the desorption tower of sulfuric acid manufacturing system of the present utility model.

5, manhole 6, inlet hole 7, outlet opening
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The tower body 1 of the utility model agent set for making of the PVC plate is provided with one deck 316L woven wire 2 at tower body 1 middle part, the silk footpath is 490Pa for 0.23mm, Resistance Value.Silk screen 2 tops are provided with spray equipment 3, and spray equipment 3 connects flushing pipe 4, and manhole 5 is set on tower body 1, and bottom, tower body left side is provided with gas feed hole 6, and tower body top is provided with gas outlet hole 7.
Sour gas is removed the mist of carrying secretly in the gas by silk screen 2 after entering tower body 1 from inlet hole 6, and purified gas flows out from the gas outlet hole 7 on tower body top.After silk screen mist eliminator resistance rises to certain value, to open flushing pipe 4 and wash a few minutes, the silk screen mist eliminator is just well cleared up.On spray equipment, be provided with manhole 5, convenient maintenance and cleaning to silk screen.
Claims (2)
