A nozzle orifice of a nozzle 1 comprises a tapered segment 16 extending from an elliptical discharge orifice 15 and having a taper angle θ of 30 to 80°, and a large-diameter segment 18 continuing with the tapered segment, and scale on a steel plate is removed by discharging water from the nozzle at a distance between discharge orifice 15 and the steel plate of not more than 600 mm, a pressure of 5 to 30 MPa, and a discharge flow rate of 40 to 200 l / minute. The ratio of the inner diameter of large-diameter segment 18 relative to the minor diameter of the discharge orifice 15 is not less than 3 and less than 7. Also, the discharge flow from the nozzle spreads in a single direction (width direction) within a plane perpendicular to the central axis of the nozzle and the erosion thickness angle is 1.5 to 30 in the direction (thickness direction) perpendicular to the width direction. Such a descaling nozzle enables that scale is removed efficiently at low pressure and / or low flow rate while restraining the cooling of a steel plate.

The invention provides a descaling device at an inner wall of a steel tube with a 20-100mm of diameter. The descaling device comprises a three-way pipe and a high-pressure pipe, wherein the high-pressure pipe passes through two interfaces of the three-way pipe; the outlet end is connected with a flow equalizing head; high-pressure airflow or water flow and mortar are directly mixed inside an inner cavity of the steel tube to be descaled by matching of the high-pressure pipe and the three-way pipe; a high-speed abrasive jet is formed to strike the inner wall; and continuous, efficient and environment-friendly removal of a roll scale at the inner wall of the steel tube is achieved. Compared with the prior art, the descaling problem of the inner wall of the small-diameter steel tube of which the inner diameter is 20-100mm is successfully solved; the descaling device is high in descaling efficiency, free of pollution to the environment, and low in descaling cost; water or air and mortar are taken as materials; the water and the mortar can be recycled; a mixing nozzle of a common abrasive jet nozzle is concealed; and the descaling device is simple in structure, small in volume, easy to operate equipment, and wide in application range, and can be applied to various fields for cleaning the inner wall, such as descaling and derusting of the inner wall of the steel tube.

Carbon dioxide aeration electrochemical descaling device and method
PendingCN110054258AImprove descaling efficiencySolve the problem of the decrease of removal rate of hardness ionsSpecific water treatment objectivesWater/sewage treatment by electrochemical methodsChemical reactionRate reduction
The invention discloses a carbon dioxide aeration electrochemical descaling device and method and belongs to the technical field water treatment. The device comprises a reactor barrel, a plurality ofcathode plates, a plurality of anode plates, an ultrasonic cleaner and an aeration pipe. Carbon dioxide is fed in the process of continuous water treatment through the aeration pipe for aeration, so that carbonate ions in water are supplemented, further removal of calcium ions is promoted, and ion migration and chemical reaction around the pole plates are promoted; aeration action delays deposition of scaling substance on the surface of each pole plate, and the objective of cleaning the pole plates can be achieved through joint action of the aeration pipe and the ultrasonic cleaner. The deviceis reasonable in structural design, the problem of hardness ion removal rate reduction caused by water alkalinity reduction in the process of continuous water treatment is solved, and electrochemicaldescaling efficiency is improved.
