Washing device of oxidation air pipe in desulphurization system

Abstract

The invention discloses a washing device of an oxidation air pipe in a desulphurization system. The washing device comprises the oxidation air pipe, a washing pipe communicated with the oxidation air pipe and a water pump mounted at the water inlet end of the washing pipe. In the washing device provided by the invention, when the pipe orifice of the oxidation air pipe needs to be washed, the water pump at the end part of the washing pipe is directly opened, and pressure water flows into the oxidation air pipe along the washing pipe and passes through the pipe orifice of the oxidation air pipe finally, and when pressure water passes through the pipe orifice of the oxidation air pipe, the water pump applies certain impact force to the pressure water, so that the pressure water can impact the dirt at the pipe orifice of the oxidation air pipe; and the water pump is opened periodically, so that the pressure water can wash the dirt at the pipe orifice of the oxidation air pipe in time, as a result, the washing device can effectively reduce the frequency of blockage at the pipe orifice of the oxidation air pipe.

Description

technical field [0001] The invention relates to the technical field of power generation desulfurization systems, in particular to a flushing device for an oxidation air pipe in a desulfurization system. Background technique [0002] With the continuous development of society and economy, the global environment is also deteriorating. All countries in the world make their own contributions to the environment and sustainable development of human beings. Low emissions and low pollution have become the goals that all countries are striving for. As a major emitter of pollutants, power plants have an unshirkable responsibility in reducing environmental pollution. Generally, power plants desulfurize substances by configuring desulfurization systems to reduce environmental pollution. [0003] In the oxidation air pipeline in the desulfurization system, the slurry is immersed in the absorption tower, and the oxidation air pipe is connected to the absorption tower, and the nozzle of ...

Problems solved by technology

However, when the operator cleans the mouth of the oxidation air pipe, the slurry in the absorption tower needs to be poured out first, and the mud remaining at the bottom of the absorption tower must be cleaned up before the dirt at the mouth of the oxidation air pipe can be cleaned. The above cleaning process takes a long time and is labor intensive

[0006] On the other hand, in order to meet the requirements of environmental protection, the bypass of the desulfurization system must be canceled, so that the desulfurization system cannot be shut down independently. If the oxidation air duct is to be cleaned, the generator must be shut down, and the oxidation air duct must be cleaned frequently, further increasing the losses in all aspects
