Annular hot-liquid-jet scale cleaning device for barrel body, and cleaning process thereof

Abstract

The invention relates to an annular hot-liquid-jet scale cleaning device for a barrel body. The annular hot-liquid-jet scale cleaning device comprises a reaction tank and an exhaust barrel, wherein a centrally-heating annular jet unit and a movable elastic ultrasonic vibration unit are arranged on the upper part of the exhaust barrel; and the centrally-heating annular jet unit comprises a first hydraulic cylinder, a first push rod, a hollow pipe, a transversal line guide pipe, a heating controller, a vertical line guide pipe, an acid conveying pipe, an acid feeding pipe, a fixed-displacement pump, a waste acid storage box, a booster pump, a spray tank, an acid liquid cavity, a spray cavity, an S-shaped spray head, a heating cavity, an acid pumping pipe and an acid inlet pipe. The annular hot-liquid-jet scale cleaning device disclosed by the invention is high in automation degree, capable of effectively removing scales of the barrel body, and high in cleaning efficiency.

Description

technical field [0001] The invention relates to the application field of cleaning technology for smelting pipelines, in particular to a ring-direction hydrothermal jet type cylinder scaling cleaning device. Background technique [0002] In the field of existing smelting technology, due to the backlog of factory exhaust gas and dust, the ventilation pipes are usually blocked, and most of the existing solutions use manual cleaning, which not only consumes a lot of manpower and material resources, but also has unsatisfactory cleaning effects. , the accumulated dust is generally solid matter such as metal or calcium carbonate, so some factories think of using acidic solution to treat the ventilation pipe, but after the acidic solution cleans the pipe, on the one hand, the acidic solution is not recovered reasonably, on the other hand On the one hand, the acidic solution remaining in the ventilation pipe will cause damage to the ventilation pipe, thereby shortening the service li...
