Abstract
The utility model relates to a liquid film overflow launder. Including inner tube and the outer tube that cup joints, the inner tube is the back taper venturi tube, and the inner tube lower extreme is connected with the smoke inlet pipeline upper end, and the upper end of inner tube and upper end and the lower extreme that the lower extreme is less than the outer tube respectively, outer tube lower extreme pass through the bottom plate to be connected with outer wall of the inner tube and to form the overflow launder between messenger's inner tube and the outer tube, be equipped with three overflow water inlet tubes in the overflow launder, be equipped with a pressure water spray painting rifle on the lateral wall of inner tube, the outer wall of the inner tube hoop is equipped with a water inlet manifold, three overflow water inlet tubes are connected with water inlet manifold. The utility model discloses overflow water in the simple structure, liquid film overflow launder makes the water film of flue gas pipeline inner wall formation downward flow, effectively prevents the scale deposit of flue gas pipeline inner wall, avoids hindering decreasing and increases.
Description
Technical field
The utility model relates to a kind of overflow launder, particularly relates to a kind of liquid film overflow launder, belongs to prevention and control of air pollution and flue gas cooling and dedusting technical field.
Background technology
Converter gas revolves mixed, collision, condensation, cohesion etc. through water smoke and can stick on flue pipe wall in flue, of long duration, easily on the inwall of flue, produce fouling, thus the resistance adding flue is damaged, and reduces the efficiency of cooling and dedusting.
Utility model content
For above-mentioned defect, the purpose of this utility model is to provide a kind of structure simple, effectively prevents tube wall incrustation, effectively avoids fouling and hinders damage and increase, improving a kind of liquid film overflow launder of cooling and efficiency of dust collection.
The technical scheme that the utility model adopts for this reason is:
Comprise the inner and outer tubes of socket, described interior pipe is back taper pipe, interior pipe lower end is connected with upper end, smoke-intake pipe road, the top and bottom of interior pipe are respectively lower than the top and bottom of outer tube, outer tube lower end to be connected with outer wall of inner tube by base plate to be made to form overflow launder between interior pipe and outer tube, three overflow water water inlet pipes are provided with in described overflow launder, the sidewall of described interior pipe is provided with a pressure water fog spraying gun, described outer wall of inner tube hoop is provided with a water inlet manifold, and described three overflow water water inlet pipes are connected with water inlet manifold.
Further, the nozzle of described pressure water fog spraying gun is positioned at the axle center place of pipe, and the nozzle direction of described pressure water fog spraying gun down.
Further, described interior pipe upper end is circumferentially provided with sawtooth mouth.
Further, water side and the outer tube wall of described three overflow water water inlet pipes are tangent, and the angle of adjacent overflow water water inlet pipe is 120 degree.
Further, the sidewall of described outer tube is provided with hand hole, and the inner of described hand hole is connected with interior pipe.
The utility model has the advantages that:
The utility model structure is simple, and the overflow water in liquid film overflow launder makes flue pipe wall form the moisture film flowed downward, and effectively prevents flue pipe wall fouling, avoids resistance damage to increase.
