Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Seeing Fig. 1-4, a kind of device for deep cleaning for wet-method desulfurized fume that the present invention provides, it carries out the purified treatment except mist and dedusting to flue gas.This device for deep cleaning includes: dividing plate 1, discharging tube and multiple separative element.
Wherein, dividing plate 1 is arranged in a horizontal manner, and be connected inside the tower wall 2 of wet desulfuration tower, so achieve and with dividing plate for boundary, smoke space is divided into purified treatment space (i.e. dividing plate underlying space) and purifies rear space (i.e. dividing plate superjacent air space).Dividing plate 1 has multiple through hole running through dividing plate end face and bottom surface, by through hole, purified treatment space connect with purifying rear space, when purification rear space connects with ambient atmosphere, it is achieved thereby that fume emission is in ambient atmosphere after Jing Huaing.
Each separative element 3 is positioned at below dividing plate 1, and one_to_one corresponding is installed on each through hole, and it has smoke exhaust pipe 31, moisture film water collector 33 and multiple rotating flow guidance blade 32.Smoke exhaust pipe 31 is arranged in vertical mode, and the top of smoke exhaust pipe 31 is installed on through hole so that the hollow space that smoke exhaust pipe 31 is formed connects with through hole, and then realizes connecting with dividing plate superjacent air space.Rotating flow guidance blade 32 is used for making flue gas produce and rotates and move downward, it is formed at the outer surface of smoke exhaust pipe 31, rotating flow guidance blade 32 is formed with rotating flow guidance curve on the direction of its initiating terminal to clearing end, the initiating terminal position of rotating flow guidance blade is higher than other positions, position of rotating flow guidance blade, and the clearing end position of rotating flow guidance blade is less than other positions, position of rotating flow guidance blade.Circumferentially distributed along smoke exhaust pipe 31 of the initiating terminal of multiple rotating flow guidance blades 32.Water smoke and dust in flue gas rely on the guide functions of rotating flow guidance blade to separate from flue gas simultaneously, it is not necessary to consume other energy, reduce energy resource consumption.Turning effort owing to relying on separative element to produce makes water smoke and dust separation, and therefore separative element is properly termed as centrifugal separative element.
It is formed with containing cavities in moisture film water collector 33, the top of moisture film water collector 33 is opening, bottom is blind end, i.e. moisture film water collector 33 is in barrel-shaped, moisture film water collector 33 is sheathed on outside rotating flow guidance blade 32, moisture film water collector 33 can contact (such as socket) with rotating flow guidance blade 32, it is also possible to do not contact with rotating flow guidance blade, i.e. moisture film water collector 33 entirety is set in outside rotating flow guidance blade in the way of keeping at a certain distance away.During installation, moisture film water collector 33 can move from the bottom to top and make rotating flow guidance blade 32 be placed in containing cavities, thus is sheathed on outside rotating flow guidance blade 32 by moisture film water collector 33.In the vertical direction, the position, top of moisture film water collector 33 is between the position, top and the position, bottom of rotating flow guidance blade 32 of rotating flow guidance blade 32.Leave space between bottom and the bottom of smoke exhaust pipe 31 of moisture film water collector 33, be beneficial to the flue gas after purifying and entered in smoke exhaust pipe 31 by this space.Preferably, water smoke in flue gas and dust are under the effect of rotating flow guidance blade 32, it is thrown out of and on the inwall of moisture film water collector 33, forms moisture film, so take full advantage of the water smoke in flue gas and flue gas in the flow direction within separative element, also have the gravity after water smoke and mix dust to complete moisture film and be gathered in the bottom of moisture film water collector 33, without additionally increasing driving force, the water source the most from top to bottom flowed is to drive moisture film slide downward from inwall.
Water smoke and dust that discharging tube 4 is used in the flue gas collected by moisture film water collector 33 are discharged, and the one mouth of pipe connects with the bottom of moisture film water collector 33, and water smoke and dust in the flue gas that moisture film water collector 33 is collected are discharged from another mouth of pipe of discharging tube 4.
During purification, the flue gas coming from wet desulfuration tower runs into the stop of dividing plate 1 in uphill process, change the direction of motion, enter above separative element 3 in separative element 3, under the effect of rotating flow guidance blade 32, flue gas produces and rotates and move downward, then the water smoke in flue gas and dust are being rotated under the centrifugal action produced by flue gas, it is thrown on the inwall of moisture film water collector 33, the liquid (i.e. water smoke) separated and dust are attached to moisture film water collector 33 inwall and form moisture film, moisture film (i.e. moisture film is along with airflow direction and under gravity of flue gas) under the promotion and self gravitation effect of flue gas flows downward, it is gathered in the bottom of moisture film water collector 33, discharged by the discharging tube 4 connected with moisture film water collector 33 bottom；And the flue gas after purifying enters the bottom of smoke exhaust pipe 31 from the space left between the bottom and the bottom of smoke exhaust pipe of moisture film water collector, and then enter the hollow space of smoke exhaust pipe 31, hollow space along smoke exhaust pipe 31 rises, dividing plate superjacent air space is entered by the through hole on dividing plate 1, the conveying of flue gas after completing to purify, thus realize flue gas and discharge after cleaning.
Water smoke in flue gas that moisture film water collector 33 is collected and dust can be entered in wet desulfuration tower by discharging tube, such as: discharging tube is U-shaped liquid sealing pipe 41, U-shaped liquid sealing pipe 41 is arranged in wet desulfuration tower, one mouth of pipe one_to_one corresponding of multiple U-shaped liquid sealing pipes 41 is communicated in the bottom of multiple moisture film water collector 33, another mouth of pipe of U-shaped liquid sealing pipe 41 is as another mouth of pipe of discharging tube, its position is less than a mouth of pipe position of U-shaped liquid sealing pipe 41, water smoke and dust in the flue gas that moisture film water collector 33 is collected are flowed out in wet desulfuration tower by another mouth of pipe of U-shaped liquid sealing pipe by gravity flow.Rise the resistance problem produced in moisture film entrance wet desulfuration tower to reduce flue gas, discharging tube can also be made up of U-shaped liquid sealing pipe 41 and collecting pipe, U-shaped liquid sealing pipe 41 is arranged in wet desulfuration tower, one mouth of pipe one_to_one corresponding of multiple U-shaped liquid sealing pipes 41 is communicated in the bottom of multiple moisture film water collector 33, another mouth of pipe position of U-shaped liquid sealing pipe 41 is less than a mouth of pipe position of U-shaped liquid sealing pipe 41, another mouth of pipe of U-shaped liquid sealing pipe 41 connects with a mouth of pipe of collecting pipe, another mouth of pipe of collecting pipe is another mouth of pipe of discharging tube, it extends downward at the bottom of wet desulfuration tower tower along the tower wall of wet desulfuration tower.
It is divided into multicomponent from module multiple separative elements 3, discharging tube is collector 42, it is in being horizontally disposed with, quantity is multiple, multiple mouths of pipe that the side of each collector 42 is formed connect with the bottom one_to_one corresponding of all moisture film water collectors 33 in often group separation module, another mouth of pipe that the mouth of pipe is discharging tube that the opposite side of each collector 42 is formed, it stretches out outside the tower wall of wet desulfuration tower, so recycles the moisture film (i.e. water smoke in flue gas and dust) of moisture film water collector 33.In reality, multiple separative element 3 regions are divided into several region, containing the separative element of more than 2 in each region, this separative element of more than 2 is referred to as separation module, arranging a collector 42 for each region, the bottom of the moisture film water collector 33 of the separative element in respective regions all connects with collector 42, and collector 42 is drawn outside wet desulfuration tower simultaneously, thus the water smoke collected by moisture film water collector 33 and dust lead to outside wet desulfuration tower, it is achieved recycle.
In actual application, the flow velocity of flue gas to be clean can be different, when actual flow velocity is less than design current velocity, the centrifugal force that then separative element makes flue gas produce is inadequate, the gas-liquid-solid separating effect of flue gas can not be reached to realize throwing away the water smoke in flue gas and dust from flue gas, when actual flow velocity is more than design current velocity, though resistance can be increased, but do not affect the gas-liquid-solid separating effect of flue gas.That is device for deep cleaning has certain requirement to flue gas flow rate, when flue gas flow rate less than design current velocity more time (when such as flue gas flow changes greatly), can have a strong impact on device for deep cleaning except mist and the effect of dedusting.The adverse effect brought to reduce flue gas flow rate to change, device for deep cleaning also includes: multiple supervisors 43, multiple supervisor's valve 44, multiple arm 45 and multiple arm valve 46.It is each header arrangement one and is responsible for 43, supervisor's 44, arm 45 of valve and an arm valve 46.Each supervisor 43 is positioned at outside wet desulfuration tower and one_to_one corresponding is communicated in the opposite side of each collector 42, the moisture film coming from moisture film water collector 33 for being collected by collector 42 is discharged, each supervisor's valve 44 one_to_one corresponding is arranged on supervisor, is used for controlling to be responsible for whether 43 connect with collector 42；Each arm 45 is positioned at outside wet desulfuration tower and one_to_one corresponding is communicated in the opposite side of each collector 42, for fluid-tight fluid is introduced in collector 42, fluid-tight fluid 47 is preferably water, and each arm valve 46 one_to_one corresponding is arranged on arm 45, is used for controlling whether arm 45 is connected with collector 42.The opposite side of collector 42, supervisor 43 and arm 45 form threeway.
When flue gas flow rate is design current velocity, arm valve 46 is closed, and supervisor's valve is opened, and separative element normally works.When flue gas flow rate diminishes, close supervisor's valve of the collector being positioned at certain region, corresponding arm valve is opened, introduce the water in this collector, again by entering the containing cavities of moisture film water collector with the outlet of the bottom of the moisture film water collector of header in communication, when liquid level in containing cavities is higher than exhaust opening (i.e. the bottom of smoke exhaust pipe) bottom separative element, by smoke exhaust pipe fluid-tight, achieve separative element fluid-tight, then flue gas will not be by the separative element in this region, only by the separative element in other regions, ensure that flue gas flow velocity in separative element, reach regulating effect.It should be noted that design current velocity is: separative element is designed under a certain gas flow rate, under this gas flow rate, gas to be made produces enough centrifugal force, it is necessary to corresponding shape and the rotating flow guidance blade of structure.And after rotating flow guidance blade design is good, not malleable, therefore it is not suitable with the gas flow rate operating mode less than design current velocity.With Fig. 3 and Fig. 4, device for deep cleaning is illustrated according to the process of flue gas change regulation.The water smoke collected in block arrow represents collector in figure and the flow direction of dust, thin arrow represents smoke movement direction, and Fig. 3 is up state.Supervisor's valve 44 of left area, supervisor's valve 44 of right area are opened in this condition, and the arm valve 46 of left area, the arm valve 46 of right area are closed, the water smoke collected by moisture film water collector and dust normal discharge.Fig. 4 is the state that flue gas change needs to regulate device for deep cleaning process exhaust gas volumn.Under this state, the separative element of left area is in normal operating condition, i.e. supervisor's valve 44 of left area is opened, the arm valve 46 of right area is closed, and supervisor's valve 44 of the separative element of right area is closed, arm valve 46 is opened, then in the water in arm is injected into moisture film water collector 33, smoke exhaust pipe 31 is blocked, then flue gas will not pass through the separative element of right area, can only reach regulation effect by the separative element of left area.
In order to beneficially the enough centrifugal force of flue gas generation is so that water smoke and dust in flue gas are thrown on the inwall of moisture film water collector, the rotating flow guidance curve that rotating flow guidance blade is formed at the outer surface of smoke exhaust pipe, i.e. rotating flow guidance blade along spiral curve is spiral curve.The preferably angle of spiral curve is 45-85 °, and this angle refers to the lead angle (i.e. lead angle) of spiral curve.The number of turns of spiral curve is 1/4-3/4, say, that spiral curve from the number of turns that its initiating terminal to clearing end is formed be the spiral curve spiralization number of turns be the 1/4-3/4 of the length of a circle.In reality, the angle of spiral curve can be different according to flue gas flow rate, the difference of separative element diameter.Such as: flue gas flow rate is the biggest, spiral curve angle is the biggest, and flue gas flow rate scope is 2-30m/s；Separative element diameter (i.e. the diameter of smoke exhaust pipe) is the biggest, and spiral curve angle is the least, and separative element diameter range is 50-800mm.On the basis of the screw-in direction of spiral curve, then the rotation direction of spiral curve is left-handed.
In vertically downward direction, smoke exhaust pipe 31 includes blade sections and cylinder section successively, and the outer surface of blade sections is formed with rotating flow guidance blade 32；Blade sections has expansion mouth and straight oral area, in vertically downward direction, the internal diameter of enlarging tapers into, the internal diameter of the bottom of expansion mouth is identical with the internal diameter on the top of straight oral area, the flue gas changing direct of travel after being so beneficial to run into dividing plate is entered by rotating flow guidance Leaf Conductance stream in the gap formed between outer surface and the inwall of moisture film water collector of smoke exhaust pipe, simultaneously, in the horizontal direction, interval is formed, it is easy to be thrown to flowing downward of the water smoke on moisture film water collector inwall and dust between the rotating flow guidance blade and moisture film water collector of cylinder section.In order to easy to connect, moisture film water collector 33 is socketed on expansion mouth, such as, bond or weld.In order to improve the sealing that the expansion mouth of smoke exhaust pipe is connected with dividing plate, prevent flue gas from letting out from junction, be provided with connection ring 311 on the top of expansion mouth, connect ring 311 and be connected with the bottom surface of dividing plate 1, such as, can be Flange joint.
In sum, the having the beneficial effect that of the embodiment of the present invention:
(1) water smoke in flue gas and dust separate from flue gas simultaneously, improve the purification efficiency of flue gas.
(2) flue gas flow velocity in separative element can be regulated in the case of by the flue gas flue gas flow rate instability brought of change, it is ensured that except mist dust removing effects and regulate simple and convenient.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
