Problems solved by technology

However, the solution in the traditional water spray system will accumulate impurity particles in the flue gas due to long-term recycling, and the solution will become acidic over time
However, the equipment mainly made of steel will be corroded under acidic conditions for a long time, which will reduce the service life of the equipment.

Abstract

The invention relates to the technical field of environmental protection, and particularly relates to a water spraying system and a waste gas treatment system. The water spray system comprises a lye tank, a metering pump, a spray water tank, a first water pump, a PH probe, a sprayer device, a tower body and a control device, wherein the lye tank, the metering pump and the spray water tank are sequentially connected; the water outlet of the spray water tank, the first pump, the water inlet of the tower body, the water outlet of the tower body and the water inlet of the spray water tank are communicated sequentially to form a first circulating system; the PH probe is arranged in the first circulating system; the sprayer device is connected with the water inlet of the tower body, and is arranged in the tower body; a smoke inlet of the tower body is formed in the lower side of the sprayer device, and a smoke outlet of the tower body is formed in the upper side of the sprayer device; and the PH probe, the control device and the metering pump are electrically connected sequentially. The water spraying system can be used for automatically adjusting the PH value of the solution in the water spraying system, so that equipment corrosion is reduced, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a water spray system and a waste gas treatment system. Background technique [0002] Since the reform and opening up, my country's industrial technology has developed rapidly. At the same time, due to the combustion of a large amount of fuel and the emission of industrial waste gas, the air quality is deteriorating day by day. At present, the awareness of environmental protection in our country is constantly strengthening, and all enterprises put the protection of the environment at the forefront of enterprise development. Therefore, the waste gas should be treated before it is discharged. [0003] At present, most exhaust gas treatment systems are equipped with a water spray system. The water spray system can reduce the temperature of the smoke when it is discharged, and can also dissolve some particles or water-soluble gases in the smoke, reducing the emission ...
