<p>The procedure for the desulphurisation of exhaust gases with integrated equipment provides the possibility that several phases of the wet calcite process of desulphurisation of exhaust gases is carried out within the same equipment, which results in a considerable reduction of the number of required appliances and devices with a generally quite complex system. During preparation of the calcite suspension and its dosage to the absorber for dampening the calcite, a small part of the absorption suspension is constantly diverted directly from the vertical recirculation pipe for the absorptive suspension, thus enabling with this flow the dampening and flushing of calcite as soon as it leaves the dosage device and is released into the wet worm gear, so that the prepared calcite suspension is by way of gravity running into the mixing container beneath the gas washing device. The hydrocyclones are fuelled from the vertical pipes of the recirculation pumps without the application of special pumps. During the time, required for maintenance, the gypsum is stored in the mixing container of the gas washing device so that the concentration of gypsum is increased, while after that the solid particles content is reduced by hydrocyclones to the standard operation level.</p> |
