Operating Rules and Regulations of Desander

First, the device structure:

It is mainly out of stock inlet on the cylindrical part, the cone, the lower part of the cone and cone nozzle, connecting flanges and sealing components and connectors and other components.

Second, Operating Rules and Regulations:

1) Check equipment in good condition before starting Desander, if there is clogging the tap outlet.

2) After starting a fan pump to regulate pressure cleaner, import and export traffic.

3) pay attention to changes in plasma concentrations of normal operation, to prevent drop slag efficiency.

4) Maximum into the plasma concentration should not exceed 1.2%.

5) Note that each segment of white water of complement .

Third, the process parameters of adjustment:

1)Normal pressure range of Desander: 2.8-3 kg into the pulp, the best period of not less than 2.8 kg, the plasma pressure control at 0.1-0.6 kg, it is usually best controlled at 0.2 kg.

2)Try to keep Desander inlet and outlet valves fully open state, especially imports to fully open the outlet valve can be as a supplement ,when the plasma pressure adjustment operation.

3)Maintain steady pressure into the slurry, if the gauge pressure is less than 2.2 kg, it may be enough to cause the amount of water added, it need to adjust the white water simply.

4)the amount of white water as much as possible to add as well, but it is not less than 15cm from the nozzle as a precondition at the slag bath surface,

.

5) Desander in normal steady state: pressure is normal and stable, slagging of the umbrella opened, but spraying can not be too hasty.

Fourth, the problem of treatment:

1)Adjustment of pressure should be adjusted on a slurry valve manifold to ensure no white water, as the tube is filled, as the tube, for the red, adjustable on a slurry valves to handle its Desander.

2)Depending on the tube in Whitewater height adjustment, there are two cases, one,maybe a slurry pressure is too high and fast slag, causing the tube Whitewater is...
