All pipelines on the chimney wall are all made of anchor ear and are fixed on chimney wall, then smooth with acid resistant adhesive mortar
Transition.
The invention further relates to energy-saving chimney anti-icing equipment according to the present invention concrete chimney, steel stack or
Application in brick chimney.
The anti-icing equipment of the present invention utilizes the existing hot water pipeline of power plant, and the hot water pipeline is from water delivery starting point to cigarette
Chimney bottom stage uses the pipeline with power plant water-carriage system same material and keeps the temperature, to prevent thermal loss.The work of the present invention is former
Reason is as follows：First, hot water is led into chimney bottom by water inlet pipe, then with high-pressure hydraulic pump by hot water by being fixed on chimney barrel
On wall on the upper hose force feed of (or inner tube wall or outer tube wall) to the water knockout drum of chimney top opening, water knockout drum has several (according to cigarette
Chimney diameter is determined), one of water knockout drum is connect with upper and lower water pipe, have top opening hot-water line to be connected with return pipe between water knockout drum,
Hot water is back to point by the anti-freeze pipe network on the outer tube wall of chimney top respectively by the water knockout drum of chimney top opening again
Hydrophone, is finally delivered to downcomer by water knockout drum and finally flows through outlet pipe and be back in the piping network of power plant.
The anti-icing equipment of the present invention solves the technical barrier of chimney top opening icing with effectively arriving, and reduces installation and fortune
Row cost, improves energy utilization rate and service life, has saved resource.
