Burda Y. Improving the efficiency of gas cleaning in scrubbers nazarkulova type

This paper analyzes the existing problems of wet scrubbing, in black metallurgy, and the search of effective methods to improve the cleaning efficiency of its emissions. The paper discusses the most effective types of wet scrubbing, and points out its advantages and disadvantages. The purpose of the scrubber as a whole is the cleaning of flue gases from dust formed during combustion of dispersed carbonaceous material. The scrubber housing is designed to organize streams of gas and droplets of water. The irrigation system is designed to supply and spray water in the scrubber housing. In this thesis we consider a model nazarkulova scrubber as the most simple and effective in the reconstruction. First the optimal parameters of thermodynamic processes (13-15°C and a pressure of 200 – 270 kPa), which provide the maximum degree of purification of coke oven gases from the foundry in scrubbers nazarkulova type. Aggregation improved movement structure of fluid and gases as a result of applying a triangular nozzle with a cross-shaped cut-outs, geometric features which ensure maximum contact of the gas with the liquid, which in turn increases the efficiency of flue gas cleaning coke oven industry from CО₂ – up to 98 %, C₁₀H₈ – up to 95 %, C₆H₆ – 93 %, dust – up to 99 %. Tests were carried out by using an alkali 15 % KOH solution, due to its absorbent and solvent properties increases the efficiency of cleaning of exhaust gases from CО₂, C₁₀H₈, C₆H₆ and dust.
