Abstract
The utility model, which is related to be sequentially provided with the tower body after bubble dust collector and demister, demister along gas flow direction in a kind of acid regeneration preconcentrator, including preconcentrator, the gas-liquid separation section of the preconcentrator, sets gas vent.The utility model increases bubble dust collector and demister in existing preconcentrator, improves the ability of preconcentrator removing iron oxide red dust and droplet, prevents the situation that pickle liquor regenerating unit emits red cigarette from occurring, with meet the requirement of environmental protection.
Description
Technical field
The utility model is related to steel cold-rolling pickling spent solution regeneration technical field, more particularly to a kind of acid regeneration pre-concentration
Device.
Background technology
At present, the conventional equipment of the pickle liquor regeneration of steel industry cold-rolled process mainly includes hydrolysis roaster, rotation
Wind separator, preconcentrator, absorption tower and scrubbing tower, for by the material high temperature such as the frerrous chloride in pickle liquor, iron chloride
Decompose, obtain hydrochloric acid solution return system and reuse；The process characteristic of the device is that flow is succinct, Processes and apparatus is ripe,
It is stable.But, often occur that chimney emits the situation of red cigarette when carrying out washings switching washing in the plant running, it is main
It is that iron oxide red dust concentration is too high (more than 30 milligrams/m in flue gas to want reason3).As China marks to industrial emissions environmental protection
Accurate raising, the situation to old red cigarette must be administered using measure；Mode most simple and easy to apply is exactly that flue gas utilization is fresh
Hydrochloric acid solution enters back into preconcentrator after returning to washing, but uses fresh hydrochloric acid solution as washing medium, and cleaning solution finally will
Hydrolysis roaster roasting is returned to, the operation energy consumption of device will necessarily be increased.Accordingly, it would be desirable to take more feasible measure to prevent
Emit the situation of red cigarette.
The content of the invention
The utility model provides a kind of acid regeneration preconcentrator, increases bubble dust collector in existing preconcentrator and removes
Day with fog, improves the ability of preconcentrator removing iron oxide red dust and droplet, prevents pickle liquor regenerating unit from emitting red cigarette
Situation occurs, with meet the requirement of environmental protection.
In order to achieve the above object, the utility model is realized using following technical scheme：
Flowed in a kind of acid regeneration preconcentrator, including preconcentrator, the gas-liquid separation section of the preconcentrator along gas
Direction is sequentially provided with the tower body after bubble dust collector and demister, demister and sets gas vent.
The gas-liquid separation section of the preconcentrator is in a single tower body, and the expanding reach bottom of preconcentrator sets gas
Liquid mixing section, gas-liquid separation section be arranged in parallel with gas-liquid mixed section；Connected between gas-liquid mixed section and gas-liquid separation section by gas
Adapter and the connection of solution connecting tube, solution connecting tube are located at the lower section of gas connection pipe；The tower body bottom of gas-liquid separation section sets liquid
Body is exported, and top sets in the tower body set in the middle part of gas vent, tower body below bubble dust collector, gas vent and sets demister.
The bubble dust collector by along gas-liquid separation section tower body cross-sectional direction set gradually seal pot, dedusting sieve
Plate, down-flow plate and receipts liquid disk composition, wherein down-flow plate is set straight down, receives the lower section that liquid disk is arranged on down-flow plate；Seal pot
Hydrochloric acid liquid inlet is set on the tower body of side, hydrochloric acid liquid outlet is set on the tower body for receiving liquid disk side.
The demister is acidproof mesh mist eliminator.
At the top of the down-flow plate overflow also is provided with higher than dedusting sieve plate between seal pot and dedusting sieve plate as downflow weir
Weir.
Compared with prior art, the beneficial effects of the utility model are：
1) ability of preconcentrator removing iron oxide red dust and droplet is improved, prevents pickle liquor regenerating unit from emitting red
The situation of cigarette occurs, with meet the requirement of environmental protection；
2) simple in construction, small investment, instant effect carries out upgrading available for existing equipment.
Brief description of the drawings
Fig. 1 is a kind of structural representation of acid regeneration preconcentrator described in the utility model.
In figure：1. the gas-liquid mixed of 6. expanding reach of high-temperature flue gas entry 2. spray gun, 3. jet segment, 4. trunnion, 5. grid 7.

Segregation section
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of acid regeneration preconcentrator described in the utility model, including preconcentrator, the preconcentrator
Gas-liquid separation section 20 in be sequentially provided with along gas flow direction on the tower body after bubble dust collector and demister 12, demister 12
If gas vent 11.

Receive in liquid disk 18, fresh hydrochloric acid solution storage tank is flow to from hydrochloric acid liquid outlet 17.Above bubble dust collector, gas-liquid separation section 20
Tower body at the top of set acidproof mesh mist eliminator, will be removed through the droplet remained in flue gas after bubble dust collector.
In order to ensure dust removing effects, the hydrochloric acid liquid inlet 13 and hydrochloric acid liquid outlet 17 on gas-liquid separation 20 tower bodies of section are logical
Piping connects fresh hydrochloric acid solution storage tank formation circulation loop respectively, it is ensured that fresh hydrochloric acid solution continuously enters bubble dust collector
Interior, the both sides of dedusting sieve plate 15 set downflow weir respectively, its surface is kept certain liquid level.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its design is subject to equivalent substitution or change, should all cover within protection domain of the present utility model.
