A molecular sieve device for wet removal of fine particles in smoke and dust

Abstract

The invention discloses a molecular sieve device for wet removal of fine particles in soot. The molecular sieve device comprises a steam removal chamber, a drying chamber and a molecular sieve removal chamber, wherein a flue gas inlet pipe is arranged at the gas inlet end of the steam removal chamber; a steam inlet pipe is arranged at the top of the steam removal chamber; a drain pipe is arranged at the bottom of the steam removal chamber; a flue gas outlet pipe is connected between the gas outlet end of the steam removal chamber and the gas inlet end of the drying chamber; a drying pipe is connected between the gas outlet end of the drying chamber and the gas inlet end of the molecular sieve movable chamber; the gas outlet end of the molecular sieve removal chamber is connected with a purified gas pipe; a molecular sieve is arranged in the molecular sieve removal chamber. Compared with the conventional sprinkling and atomizing method, water is saved. The molecular sieve device is simple in structure, low in removal cost and high in removal efficiency.

Description

technical field [0001] The invention belongs to the technical field of flue gas dedusting of industrial furnaces and power plant boilers, and in particular relates to a molecular sieve device for wet removal of fine particles in flue dust. Background technique [0002] With the large-scale development of industrialization, the amount of flue gas emitted by industrial kilns and power plant boilers has increased year by year, resulting in a sharp increase in the concentration of fine particles in the atmosphere. These fine particles are rich in a large number of toxic and harmful substances, and the residence time in the atmosphere Long, transport distance, thus causing great harm to human health and atmospheric environment quality. [0003] At present, most industrial furnaces have installed dust removal equipment on the flue, and the more commonly used ones are bag filter and electrostatic precipitator. The price of the bag filter is moderate, the floor area is large, the p...

Problems solved by technology

[0004] In the above devices, if the removal efficiency of fine particles is to be improved, the complexity of the structure of the dust removal device will inevitably be increased, and the processing and manufacturing costs will be increased.
