Intelligent monitoring and purifying system for exhaust emission of thermal power plant

Abstract

The invention provides an intelligent monitoring and purifying system for exhaust emission of a thermal power plant. The intelligent monitoring and purifying system comprises a boiler and a control terminal, wherein a high-temperature pretreatment tank is arranged on one side of the boiler; a washing tower is arranged on one side of the high-temperature pretreatment tank; a sedimentation tank is arranged on one side of the washing tower; a purifying liquid mixing tank is arranged at one end of the sedimentation tank and is connected with a washing tower pipeline; a water pump is mounted between the purifying liquid mixing tank and the washing tower; an exhaust monitoring device is mounted at the upper end of the washing tower; a smoke exhaust pipe is arranged at the upper end of the exhaust monitoring device; a third electronic valve is mounted on the smoke exhaust pipe in a sleeving manner; the control terminal comprises an intelligent control unit; and the intelligent control unit comprises a purifying unit, an exhaust detection unit, a command transmission unit and a data receiving unit. The intelligent monitoring and purifying system for exhaust emission of the thermal power plant is simple and reasonable in structure, novel in design, relatively high in practicability and convenient to widely popularize and use.

Description

technical field [0001] The invention relates to the field of waste gas discharge monitoring and purification, in particular to an intelligent monitoring and purification system of waste gas discharge in thermal power plants. Background technique [0002] China is a typical coal-rich country, and its domestic electricity is mainly coal-fired thermal power generation. As of the end of 2013, my country's power generation installed capacity exceeded 1.2 billion kilowatts, of which thermal power was 862 million kilowatts, accounting for 69.13% of the total installed capacity. The installed capacity of coal power reached 786 million kilowatts. The installed capacity of coal power per unit land area in the eastern region far exceeds that in the northwestern region, and the air pollution emissions per unit area also far exceed the national average. [0003] Many cities are currently aiming at "coal-to-gas" as the way out to control air pollution, but they are seriously constrained...

AI Technical Summary

Problems solved by technology

[0006] The existing intelligent monitoring and purification system for waste gas emission in thermal power plants fails to realize automatic control, and a large number of manual controls will be used, which will cause a large number of dangers caused by manual operations and damage to equipment. Therefore, we have improved this and proposed a fire Power plant exhaust emission intelligent monitoring and purification system
