Abstract

The invention relates to a flue gas dust-removing and mercury-removing system. The flue gas dust-removing and mercury-removing system mainly comprises a flue gas temperature control pipe, a flue gas oxidation tower, a flue gas dust-removing device and a mercury-adsorbing chamber which are connected with one another sequentially. According to the flue gas dust-removing and mercury-removing system provided by the invention, coarse-particle and fine-particle dust is separated from high-temperature flue gas by filtering for many times by physical filtration and static adsorption methods and by effectively settling, so that large-particle mercury is initially removed from the flue gas and the system is favorable for the load of the subsequent flue gas mercury-removing equipment; digital detection equipment is also provided, and digital detection signals can be output to a main control device, so that the automatic control purpose can be achieved. During mercury removal, the temperature of the flue gas is controlled to be about 140 DEG C through the temperature control pipe, the flue gas is oxidized by spraying chlorine to generate gas-phase mercury ions, the gas-phase mercury is adsorbed through bromine-carried active carbon, and finally the residual mercury and sulfide are adsorbed completely by spraying ammonia water. The whole flow is simple and short and the mercury-removing effect is good.

Description

technical field [0001] The invention relates to a waste flue gas dedusting and mercury removal treatment device. Background technique [0002] my country is one of the few countries in the world that use coal as the main energy source. Coal accounts for more than 70% of my country's primary energy production and consumption. The emission of combustion waste gas such as sulfur dioxide and nitrogen oxides has formed a huge environmental pollution. , It is imperative to fundamentally control the pollution caused by the discharge of sulfur dioxide and nitrogen oxides. [0003] Because a large amount of flue gas and fly ash will inevitably be produced in industrial production, and the flue gas also contains a large amount of fine particle dust, the direct discharge of these dusts will cause serious pollution to the environment, cause varying degrees of damage to the ecological environment, and bring harm to people. hazards to health and life. Environmental protection organizatio...
