Hydraulic ash removal water treatment plant

Abstract

The purpose of the paper is to present a treatment plant for hydraulic ash sluicing waters containing a system of flow-through inductors made in the form of a pipe with a coaxial cable, which are connected to an AC source and interconnected between each other by electricity using an end jumper. It is found out that today ash and slag from CHP boilers are hydraulically removed and stored in ash disposal areas. At the same time the slag ash pulp is supplied under pressure (created by bagger pumps) through the pipelines on the fixed distances, then it is clarified and poured into a reservoir from which it enters the nearest river or lake basin. Since the water clarified in the ash sump contains dissolved salts and bases, it represents itself an aggressive medium. This fact prevents it from direct transportation of ash and slag as bagel pumps fail quickly in the aggressive medium. It is proved that the engineering task (the solution of which involves the use of a treatment plant for hydraulic ash sluicing waters) consists in the high-performance treatment of CHP waste waters with induction currents in order to reduce their aggressiveness and recycling. The solution of the problem is in the fact that the water treatment plant includes a system of flow-through inductors, each of which is made in the form of a pipe with a co-axial cable.
