Abstract
The invention discloses a cyclone, and belongs to the field of environmentally-friendly dust removal. The cyclone comprises a cylindrical shell, wherein the shell consists of an outer wall and a cavity. The cyclone is characterized in that: one end of the shell is provided with a conical cylinder, the conical tip of the conical cylinder is provided with a water outlet, and the shell above the conical cylinder is provided with an air inlet. Smoke dust carrying liquid drops enters the cavity and rotates along the inner wall to form rotational flow; and dust particles and liquid drops in the smoke are thrown to the inner wall of the cyclone under the action of centrifugal force, flow into the conical cylinder under the action of gravity and are discharged from the water outlet. The smoke rotationally rises and is discharged from an exhaust port, so the purpose of gas-water separation is fulfilled.
Description
Technical field
The invention belongs to environmental protection dedusting field, be mainly used in dust-removal and desulfurizing, be specifically related to a kind of cyclone.
Background technology
At present, be used for coal-fired flue-gas wet desulphurization technology and adopt spray absorber or eddy flow plate absorption tower mostly, eddy flow plate absorption tower is to make liquid (absorption liquid) from top to bottom contact with flue gas by the eddy flow plate in the tower, flue gas dispels liquid, atomize, make sulfur in smoke and akaline liquid neutralization reaction, to reach the purpose that removes sulfur dioxide.In order to reach higher absorption efficiency, requiring has very high liquid-gas ratio, just can reach than higher absorptivity.And enough liquid-gas ratios can't be realized in eddy flow plate absorption tower, thereby also just very high absorptivity can not be arranged.When flue gas passes through eddy flow plate absorption tower, produce rotation, under action of centrifugal force, it is separated to get rid of Xiang Tabi.Because the tower body diameter is big (generally more than one meter) (1---4 rice), the centrifugal force that rotation produces, be not enough to separate all tiny drops, quite a few fine drop of finishing absorption reaction arranged, flue and air-introduced machine are caused corrosion along with flue gas carries out the absorption tower.The spray absorber structure is comparatively simple, and liquid is scattered in the gas in the mode of fine drop, and gas is continuous phase, and liquid is decentralized photo, has advantages such as the big and gas-phase pressure drop of the area of contacting is little.Be applicable to moment, interface and fast reaction, also be applicable to the reaction that generates solid.It is little too small with liquid side mass tranfer coefficient that the spray column reactor has liquid holdup, and gas phase and backmixing of liquid phase be important disadvantages comparatively.
Summary of the invention
The invention provides a kind of preferably cyclone of gas-liquid separation effect, its purpose is to improve removes fog effect, to improve dehydration rate, alleviates the corrosion to back-end ductwork and facility.
The object of the present invention is achieved like this: it comprises cylindrical housings, and housing is made of outer wall and inner chamber, and an end that it is characterized in that housing is a conical tube, and the awl tip of conical tube is provided with delivery port, and the housing of contiguous conical tube is provided with air inlet.
The inwall of described air inlet outside inwall and cylindrical tube is tangent.
The length of described air inlet account for cylindrical housings length 1/2 ~ 1/10.
The axle of the circular cone of described conical tube and the angle between the bus are 10 degree ~ 75 degree.
The diameter of described delivery port is 5 ~ 50mm.
The inwall of described conical tube is provided with blocker plate.
Described air inlet is rectangular, and the length of its rectangle and wide ratio are 1/2 ~ 1/10.
The external diameter of described cylindrical housings and the ratio of length are 1/2 ~ 1/10.
Operation principle of the present invention: the flue gas that has grit is referred to as flue dust, flue dust is carrying drop and is entering into inner chamber together by rectangular air inlet and rotate along inwall, form eddy flow, grit in the flue gas, drop are under action of centrifugal force, be thrown toward the inwall of cyclone, and under the effect of gravity, flow into conical tube, discharge by discharge outlet.Flue gas is rotating rising and is discharging from exhaust outlet, thereby reaches the purpose of gas-water separation.
Blocker plate can be slowed down the rotary water current that flows in the conical tube, thereby fast water is discharged from discharge outlet.
Gas-liquid separation effect of the present invention is good, and demist is effective, the dehydration rate height, thus alleviated the corrosion of water smoke to back-end ductwork and facility.
