Water supply system for overflow weir of dynamic wave washing tower

Abstract

The invention relates to a water supply system for an overflow weir of a dynamic wave washing tower. The water supply system comprises a washing tower body, a circulating pump and a settling system, wherein a circulating liquid draining pipe and a dynamic wave reverse spraying pipe are arranged on a side wall on one side of the washing tower body; the overflow weir is arranged on the top of the dynamic wave reverse spraying pipe; a reverse sprayer is arranged in the dynamic wave reverse spraying pipe; the reverse sprayer is connected with the circulating liquid draining pipe through a liquid spraying pipe; the circulating liquid draining pipe is arranged on the lower end of the washing tower body; the circulating pump is arranged on the circulating liquid draining pipe; some water in the circulating liquid draining pipe is supplied to the reverse sprayer through the liquid spraying pipe; the remaining water in the circulating liquid draining pipe is supplied to the overflow weir through the settling system. The water supply system for the overflow weir of the dynamic wave washing tower provided by the invention is capable of preventing the annular pipe of the overflow weir from being blocked by sludge, is capable of effectively controlling the water inflow of the overflow weir and is difficult to cause the erosion of the overflow weir.

Description

technical field [0001] The invention relates to a dynamic wave washing system, in particular to a water supply system for an overflow weir of a dynamic wave washing tower. Background technique [0002] Power wave scrubber system is a form of scrubber, which is widely used in the purification of acid flue gas, and has efficient dust removal and cooling capabilities. Its working principle is that the flue gas of acid making enters from the top of the power wave reverse nozzle, flows from top to bottom, and collides with the washing liquid ejected from the nozzle reversely from bottom to top, creating a turbulent flow area for rapid and continuous gas-liquid exchange, and the smoke Dust and heavy metal impurities in the gas enter the liquid phase. When the momentum of the smoke and liquid is balanced, the liquid falls to the lower reservoir. After the flue gas is dedusted and cooled, it enters the gas cooling tower for further treatment. However, in practical production, the...

Problems solved by technology

However, in practical production, the overflow weir, one of the main components of the dynamic wave washing system, often suffers from ablation and mud accumulation in the ring pipe, resulting in low operating rate of the entire system and frequent shutdowns, which greatly affects the normal operation of the system.

[0003] The main reason for frequent ablation of the overflow weir and blockage of ring pipe mud is the insufficient water supply method of the overflow weir. The other way is to supply water to the overflow weir through the power wave scrubber through the circulation pump while supplying water to the overflow weir through the power wave scrubber. Both of these two water supply methods have water quality and mud content. High, it is easy to cause mud accumulation in the ring pipe of the overflow weir, and it is not easy to control the water inflow of the overflow weir, and it is easy to cause frequent defects such as ablation of the overflow weir
