Description

A kind of desulfurizing tower pressure flow mixing device of high-efficiency desulfurization flue gas wet cleaning
Technical field
The invention belongs to aluminium cell technical fields, and in particular to a kind of high-efficiency desulfurization of high-efficiency desulfurization flue gas wet cleaning The desulfurizing tower of flue gas wet cleaning forces flow mixing device.
Background technique
At present in coal burning process and calcine technology system, disappear since raw material contains more sulfur content and raw material oxidation It consumes, the pollutants such as a large amount of sulfur dioxide is generated in flue gas system, and China's clean emission standard sulfur dioxide limit value is 35mg/ m3, very high to the desulfurizing and purifying efficiency requirements of desulphurization system.Existing desulfurization technology divides dry method, semidry method, wet process three classes, Middle dry method, semidry method are not enough the requirement for not being able to satisfy national clean emission, wet cleaning system pair due to reacting after contact The purification efficiency of sulfur dioxide is relatively high, but most of purification systems cannot reach clean emission due to contacting not exclusively It is required that.
Summary of the invention
The object of the present invention is to provide a kind of desulfurizing towers of high-efficiency desulfurization flue gas wet cleaning to force flow mixing device, and use is wet The method of method purification is designed by structure and is realized in equipment towards the uniform diffusing of different directions, eliminated during gas phase flowing Large-scale vortex and local return, improve flow uniformity and efficiency in equipment, are uniformly distributed comprehensively by gas-liquid and multiple level The mode of contact strengthens gas-liquid mixed, improves system equipment purification efficiency.
Technical scheme is as follows:
A kind of desulfurizing tower of high-efficiency desulfurization flue gas wet cleaning forces flow mixing device, including shell, be equipped on the downside of shell into Air port, case top are equipped with air outlet, and housing bottom is equipped with ash bucket and discharge outlet, is equipped with recirculated water above hull outside and takes over, It is equipped with jet pipe and nozzle with the enclosure interior of recirculated water adapter tube corresponding position, is equipped with demister, demister above jet pipe and nozzle Top is equipped with washing jet pipe.
Preferably, shell wall side is equipped with inspection manhole, and shell is externally provided with auxiliary equipment, auxiliary equipment include inspection platform, Ladder, guardrail etc..
Preferably, it is equipped in shell and forces mixed flow case structure, the wall surface of the pressure mixed flow case structure is equipped with diffusing hole. Air inlet enters the pressure mixed flow case structure at middle part below tower body from shell, is in pressure four peripheral wall surfaces of mixed flow case structure Ladder-like distribution aperture, flue gas enter desulfurizing tower washing desulphurization from aperture, are forcing in mixed flow case structure, flue gas is forced It is evenly distributed to desulfurizing tower lower part, is uniformly risen under the action of blower negative pressure, and is mixed washing only with multi-wash liquid Change, realizes the target of purification.
Preferably, stepped be evenly arranged in the diffusing hole is forced on mixed flow case structure surrounding side wall.The structure can be with Remove smoke the air-flow that liquidates, and reduces the vortex in equipment, realizes that flue gas is evenly dispersed around from pressure mixed flow box-structure Purpose.
Compared with the prior art, the present invention effectively makes gas-liquid Forced Mixing by control flow of flue gas and circulation fluid flowing Harmful substance in gas is absorbed dissolution, achievees the purpose that purification, which connect gas-liquid mixed effectively by contact, liquid Touching, improves the contacting efficiency of system equipment, to make purification efficiency greatly improve, in effectively control cleaning solution alkali concentration In the case of, realize the target of national clean emission, therefore the present invention has good promotional value and use value.

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the desulfurizing tower of high-efficiency desulfurization flue gas wet cleaning of the invention forces flow mixing device, including Shell 1 is equipped with air inlet 2 on the downside of shell 1, air outlet 3 is equipped at the top of shell 1, and 1 bottom of shell is equipped with ash bucket and discharge outlet 4, shell 1 outside top of body, which is equipped with inside recirculated water adapter tube 7, with the shell 1 of 7 corresponding position of recirculated water adapter tube, is equipped with jet pipe and nozzle 8, spray It is equipped with demister 9 above pipe and nozzle 8, washing jet pipe 10 is equipped with above demister 9.1 wall surface of shell is equipped with inspection manhole 11, shell Body 1 is externally provided with auxiliary equipment 12, and auxiliary equipment 12 includes inspection platform, ladder, guardrail etc..
It is equipped in shell 1 and forces mixed flow case structure 5, the wall surface of the pressure mixed flow case structure 5 is equipped with diffusing hole 6.It dissipates Stepped be evenly arranged on of discharge orifice 6 is forced on 5 surrounding side wall of mixed flow case structure.
The present invention is implemented: flue gas enters the pressure mixed flow case at middle part below tower body from the air inlet 2 of shell 1 Formula structure 5 forces stepped distribution in 5 four peripheral wall surfaces of mixed flow case structure to open up diffusing hole 6, and flue gas is by forcing mixed flow Under 5 metering function of case structure, partial fume is risen by reflux, is risen fluctuation and is identical with ladder distribution aperture, thus It is forced to be evenly distributed to desulfurizing tower lower part, the washing desulphurization since aperture enters desulfurizing tower lower part, in the work of blower negative pressure It is mixed washing, purifying with lower uniform rising, and with multi-wash liquid, and short distance secondary spraying is washed, the cigarette after being cleaned Gas is discharged into atmosphere after dehumidifying finally by demister.
Certainly, above is specific application example of the invention, and there are other embodiments of the invention, all using equivalent The technical solution that replacement or equivalent transformation are formed, all falls within protection scope of the presently claimed invention.
