Scrubber system for chemical waste plant

Quench

The primary function of the quench vessel is to cool the gas flow, thereby having some washing effect. By means of two spray layers with spray nozzles with a very fine homogeneous spray pattern, the incoming gas will be further cooled back. By mounting the vessel sufficiently high, the rinsing water can flow freely to the buffer tank from the scrubber.

SO2 Removal Scrubbers

The scrubber is equipped with fully removable multiple spray lances that are mounted above each other to achieve a long spray pattern. The clog-free tangential hollow cone nozzles do their job with a fine drop to capture as many gas particles as possible. The section is constructed in such a way that, due to their combined large flow rate, the nozzles flush the inside of the washing section well at the same time. The nozzles are mounted with an overlapping spray pattern, creating a very intensive cleaning system. This means that the contaminated gas cannot pass through the spray section without being moistened and cleaned. As a result, random packings are completely unnecessary, so that the pressure loss is very low and remains low. The quality of the washing water is measured. Based on the measured values, it is then possible to flush automatically and then top up with fresh water.

Droplet Separation with Wire Mesh Demister

To limit the loss of washing medium as much as possible, a final separator in the form of a very fine wire mesh demister is mounted above the pre-separator. This wire mesh demister ensures a final separation of droplets and in this configuration combines a high degree of separation with a relatively low-pressure loss.

Oxidation Columns for MgSO3 to MgSO4 Conversion

The primary function of the oxidizer is to oxidize MgSO3 to MgSO4, this oxidation takes place through an intensive contact of MgSO3 and air. By means of nozzles, the liquid will be finely distributed, and the blown air will come into contact with the liquid and oxidation will take place. To limit the loss of washing medium as much as possible, a final separator in the form of a very fine wire mesh demister is mounted above the pre-separator. This wire mesh demister ensures a final separation of droplets and in this configuration combines a high degree of separation with a relatively low-pressure loss. Fresh water is used to compensate the evaporation loss.
