Energy-saving type smoke plume removing climate feedback dynamic control device and method

Abstract

The invention discloses an energy-saving type smoke plume removing climate feedback dynamic control device and method. Under the condition of inputting atmospheric temperature, humidity and wind speed, through changing of the outlet smoke temperature of a smoke condensation heat exchanger, the lowest outlet smoke temperature of a smoke reheater under the condition of removing smoke plume is predicated, the device and method are adopted for achieving the aim of accurately and rapidly predicating and controlling the outlet smoke temperature of the smoke condensation heat exchanger and the outletsmoke temperature of the smoke reheater dynamically, real-time running cost is lowest, through the MySQL, the smoke plume parameter database is removed, a system evaluation system is built, outlet smoke temperatures, with the lowest full life circle cost, of the smoke condensation heat exchanger and the smoke reheater are selected as heat exchanger target design temperature, the temperature of the smoke condensation heat exchanger and the design parameters of the smoke reheater are determined, the control device is used for carrying out dynamic control, and the initial cost and running maintaining cost of the heat exchanger can be reduced.

Description

technical field [0001] The invention relates to the field of dynamic control of flue gas condensation heating to eliminate smoke plume (commonly known as whitening), in particular to an energy-saving climate feedback dynamic control device and method for eliminating smoke plume. Background technique [0002] With the sustained and rapid development of my country's economy, the consumption of fossil energy is increasing year by year, and the air quality is deteriorating day by day. [0003] In order to achieve ultra-low emission requirements, most thermal power plants use limestone / gypsum wet desulfurization to remove SO 2 . Using this method, the emission of SO 2 The concentration is controlled at 20mg / m 3 However, if this method is used for desulfurization, the exhausted flue gas contains a large amount of saturated water vapor, soluble salt aerosol with a particle size of less than 5m, SO 3 / H 2 SO 4 , HF, HCl and other acid gases. SO 3 and soluble salt aerosols wi...

Problems solved by technology

However, if the exhaust gas temperature is too high, more heat consumption will be invested in the reheating process, which will increase the cost of the entire enterprise
