Abstract
The utility model relates to a spiral water gas separat device, including deposit room, helical coiled passage, separation chamber, drain pipe, breakwater. Coal -fired flue gas velocity of flow suddenly in the deposit room reduce, and great water droplet and the dust particle of particle diameter subsides under the action of gravity, and the flue gas is high -speed rotatory in helical coiled passage, through slight water smoke in the centrifugal force separation flue gas, is applicable to and reduces the moisture content of coal -fired equipment in discharging fume, and reduction vapor is to atmospheric emission.
Description
Technical field
This utility model is related to a kind of spiral liquid-gas separation device, is the environmental protection product related to purifying coal-fired flue gas process
Product, it is adaptable to reduce the moisture in coal combustion equipment smoke evacuation, reduce discharge of the vapor to air.
Background technology
Coal burning can produce substantial amounts of soot dust granule thing and oxysulfide, at present using it is more be to adopt wet desulphurization
The mode of dedusting removes these pollutant, and because flue-gas temperature and flow velocity are higher, this allows for the process of Jing wet type desulfurizing dust collectors
Substantial amounts of aqueous water is carried in the flue gas crossed, cause steam generator system back-end ductwork and equipment junction there is leak, sternly
The safe operation of equipment is have impact on again.High-humidity gas fume enters the generation that air exacerbates haze again, and environment is caused greatly
Destruction.
There are cyclone type gas-water separator, baffle plate type moisture trap and silk screen using more universal liquid gas separation equipment
Demister etc., or these mode liquid edema caused by disorder of QI are from inefficient, or being susceptible to blocking, it is impossible to effectively solving coal-fired flue-gas band
Water problems.
Know-why
When swiftly flowing flue gas abrupt deceleration, the larger water droplet of the particle diameter of carrying and grit are in action of gravity in flue gas
It is lower to settle；There is density contrast in water smoke and flue gas, when flue gas rotary motion, the trickle water in flue gas under the action of the centrifugal force
Mist is thrown to wall and condenses, so as to realize the separation of fine droplet.
The content of the invention
The purpose of this utility model is to provide a kind of spiral liquid-gas separation device, can effectively remove the liquid of flue gas carrying
State water, is not susceptible to blocking, it is to avoid steam generator system afterbody occurs leak, reduces discharge of the vapor to air.
The purpose of this utility model is achieved in that a kind of spiral liquid-gas separation device, including expansion chamber, spiral lead to
Road, separation chamber, drain pipe, water fender.
Described helical duct one end connection expansion chamber, other end connection separation chamber.
There are spiral flow deflector and tube core inside described helical duct.
Described separation chamber is provided with drain pipe and water fender.
Described expansion chamber actual internal area is more than 2 times of its leading inlet flue cross section product.
Described expansion chamber connects one or more helical ducts.
Described helical duct is cylinder or cone.
Coal-fired flue-gas enter flow velocity after expansion chamber and reduce suddenly by flue, and the larger water droplet of particle diameter and grit are in weight in flue gas
The lower sedimentation of power effect, flue gas is rotationally advancing into after helical duct, and under the action of the centrifugal force the water smoke in flue gas is in helical duct
Tube wall on condense, the water droplet and flue gas of condensation are realized separating by separating indoor water fender, then by separation chamber bottom
Drain pipe discharge system outside.
When this utility model is used, coal-fired flue-gas moisture is greatly lowered, it is to avoid steam generator system afterbody leak shows
As, discharge of the vapor to air is reduced, alleviate the generation of local haze.Advantage of the present utility model has：
(1) liquid edema caused by disorder of QI is higher than 90% from efficiency；
(2) SR is less than 300pa；
(3) it is not susceptible to blocking.

Pipeline；2-1 spiral flow deflectors；2-2 tube cores.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail：
A kind of spiral liquid-gas separation device, as shown in figure 1, including expansion chamber 1, helical duct 2, separation chamber 3, drain pipe
4, water fender 5.
Coal-fired flue-gas enter expansion chamber 1 by flue 6 through connecting pipe 7, and the flue gas actual internal area of expansion chamber 1 is flue
3 times of actual internal area, velocity of flue gas declines suddenly in expansion chamber 1, and the larger water droplet of particle diameter and grit are under gravity
Settle, depart from flue gas.Expansion chamber 1 connects three helical ducts 2, and each helical duct 2 is interior to be provided with spiral flow deflector 2-
1, spiral flow deflector 2-1 center connects tube core 2-2, and flue gas is entered after helical duct 2 and revolved at a high speed under spiral flow deflector 2-1 effects
Turn to advance, due to there is density contrast, the water smoke in flue gas is thrown under the action of the centrifugal force on the tube wall of helical duct 2 to be occurred to coagulate
Knot.The detached water droplet of generation and flue gas are entered in separation chamber 3 together, and droplets impact is dropped in separation chamber on water fender 5, then
3 bottom, outside the discharge system of drain pipe 4 of the bottom of separation chamber 3, flue gas is then entered in flue 6, so as to realize along passage
Water is separated with flue gas.
Jing calculates, and the water for having more than 90% in flue gas is separated, and the absolute humidity of flue gas is greatly lowered, liquid edema caused by disorder of QI
No longer there is the phenomenon of leak in the flue through steam generator system afterbody and equipment junction in the flue gas after.Due to entering
The vapor of air is reduced, so greatly alleviating the generation of local haze.
Above disclosed is only this utility model preferred embodiment, it is impossible to the power of this utility model is limited with this
Sharp scope, according to the equivalent variations that this utility model claim is made, still belongs to the scope that this utility model is covered.
