Description
Technical field
The invention belongs to wet cleaning equipment field, and in particular to a kind of device of wet cleaning spray washing.
Background technology
In smelt production, flue-gas temperature is higher and carries substantial amounts of flue dust, it is necessary to wet for ambrose alloy pyrometallurgical smelting factory
Dedusting, cooling are carried out in method purification to flue gas during smelting.Wet cleaning uses the form of three tower dedustings cooling, and the first two purge column rises
Leading role, the latter purge column play watershed, using spray supervisor plus spray branch pipe typically in the first two purge column
Method, sour water is sprayed using shower nozzle and contact with flue gas adverse current to have the function that dedusting, cool, still, wet-process clean is disguised
Put using unilateral horizontal access intake method, cause flue gas to enter tight in the Flow Field Distribution bias current of spraying layer porch after rising in tower
Weight, easily causes the short circuit of tower wall flue gas, and flue gas is exported from absorption tower without spraying layer and escaped so that the efficiency of dust collection of the device is not
Foot far can not reach the requirement of minimum discharge.Existing spray branch pipe is all straight tube, and this method is not avoided that or solved
The problem of tower wall flue gas short circuit.
The content of the invention
The invention provides a kind of device of wet cleaning spray washing, solve due to the short circuit of tower wall flue gas and caused by
The problem of dedusting is not efficient enough：
The present invention is achieved through the following technical solutions：
A kind of device of wet cleaning spray washing, including point acid supervisor, a point acid supervisor are fixedly installed in purge column；Its feature
It is：Described point of acid supervisor both sides are provided with the branch pipe of multiple arcs shape, and two mouths of pipe of branch pipe connect with a point acid supervisor；It is described
Branch pipe is arranged symmetrically around point acid supervisor's axis；Described point of acid supervisor is equipped with shower nozzle with the branch bottom of the tube.
The shower nozzle is spiral nozzle.
Spacing is equal between shower nozzle on each branch pipe.
Described point of acid supervisor is detachably connected with branch pipe.
Branch pipe outer wall contacts with purge column tower wall described in outermost layer.
The branch pipe is semicircle.
Beneficial effects of the present invention：The present invention point acid supervisor both sides are provided with multiple arcs branch pipe, and two mouths of pipe of branch pipe are equal
Connected with a point acid supervisor；Circulation sour water in purge column is squeezed into point acid by washing pump and is responsible for, and right full of point sour endless tube immediately
Sprayed afterwards by shower nozzle, be covered with cross sectional planes in tower, flue gas and tower cross section acid solution moisture film counter current contacting are most of in flue gas
Flue dust is washed into recycle acid；It is not efficient enough to solve the problems, such as to occur dedusting under tower wall flue gas short-circuit conditions, meanwhile, if
After one shower nozzle is blocked by sour mud, the sour water that the shower nozzle of surrounding sprays can be that this region supplements sour water, to greatest extent will ensure
Flue gas and the complete counter current contacting of acid solution water film of purge column cross section.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is nozzle structure schematic diagram of the present invention.
Embodiment
A kind of device of wet cleaning spray washing, including point acid supervisor 1, a point acid supervisor 1 are fixedly installed in purge column；
Described point of 1 both sides of acid supervisor are provided with multiple arcs branch pipe 2, and 2 two mouths of pipe of branch pipe connect with a point acid supervisor 1；Described point of acid
Supervisor bottom is welded with base 3, and base 3 is connected with shower nozzle 4.
The branch pipe 2 makes the acid that point shower nozzle of sour supervisor both sides sprays uniformly divide around point acid supervisor's 1 axisymmetrical arrangement
Cloth, beneficial to forming tower cross section acid solution moisture film.
Spacing is identical between each branch pipe 2, it is ensured that the acid solution moisture film of formation is uniform.
The shower nozzle 4 is spiral nozzle, the scope that increase acid solution sprays.
Each 4 spacing of the shower nozzle are equal, it is ensured that the acid solution moisture film of formation is uniform, in addition, being blocked in indivedual shower nozzles
When, the acid solution that adjacent shower nozzle sprays can be compensated for, and not interfere with the formation of acid solution moisture film.
Described point of acid supervisor is detachably connected with branch pipe, and specifically flange connects, installation easy to disassemble, beneficial to maintenance.
The branch pipe is semicircle, and branch pipe contacts with purge column tower wall described in outermost layer, is adapted with the structure of purge column,
Ensure that the whole tower section that rinses is completely covered acid solution moisture film.
Normal concentration SO during normal production2Flue gas（SO2Mean concentration：9%, average exhaust gas volumn：180000 Nm3/h）Washing
In tower, the circulation sour water in scrubbing tower is squeezed into point acid by washing pump and is responsible for, and immediately full of a point sour endless tube, is sprayed by shower nozzle,
Be covered with cross sectional planes in tower, when flue gas in tower from top to bottom through when, and tower cross section moisture film counter current contacting is big in flue gas
Part dirt will be washed into recycle acid, and on the other hand, more heats are brought into recycle acid in flue gas.Now, take sour in tower
Water analysis solid content, it is 5g/l, the observation scrubbing tower gateway flue gas temperature difference, is 3 DEG C.
