Desulphurization emergency water source system

Abstract

The invention discloses a desulphurization emergency water source system. The desulphurization emergency water source system comprises a process water tank and an emergency reserve water tank. The emergency reserve water tank communicates with the process water tank through three emergency reserve water pipelines. The three emergency reserve water pipelines are the first pipeline, the second pipeline and the third pipeline. The second pipeline and the third pipeline separately communicate with a circulating water incoming water pipe in a power plant and a fire water incoming water pipe. A firewater pipeline communicates with the third pipeline and communicates between the process water tank and the communicating joint between the fire water incoming water pipe and the third pipeline. A serial pipeline is further arranged between a process water pipeline of the process water tank and the fire water pipeline. The ends of the fire water pipeline and the process water pipeline communicatewith a water distributing pipeline. Eight branch pipelines are arranged on the water distributing pipeline. The water outlet end of a return water reuse pipeline communicates with the process water tank. The fire water pipeline can supply water to the process water tank. In the case of water supply interruption of the process water tank, sealing water, cooling water, pipeline flushing water, limestone slurry tank water replenishment, absorption tower water replenishment and the like of each equipment can be operated normally.

Description

technical field [0001] The invention belongs to the technical field of desulfurization technology, and in particular relates to a desulfurization emergency water source system. Background technique [0002] In recent years, with the strengthening of environmental protection awareness and the improvement of environmental protection laws and regulations, desulfurization construction projects have increased year by year. Because the original absorption tower system of the desulfurization process did not lead the fire water system to each platform layer of the absorption tower, the fire water is only installed in the absorption tower. In the surrounding factory buildings, the efficiency of emergency rescue will be affected after a fire occurs; secondly, the desulfurization process water system only has an independent power plant circulating water supply system. If the process water supply is interrupted or all process water pumps trip, the safe operation of the equipment cannot b...
