Problems solved by technology

The disadvantage of this water inlet method is that the calcium carbonate particles in the filter are compacted during the experiment, which is easy to cause blockage of the flow path, and once a problem occurs in a certain part, it needs to be repaired before it can continue to run. The fault tolerance rate of the entire system lower

Abstract

The invention discloses a fair current and countercurrent double-current calcium carbonate filter belonging to the field of industrial water treatment. The structure of the filter comprises a water pump, a three-way diverter, a calcium carbonate filtration column, submerged elbow with cover, a valve, a check valve and a shell. The filter can be used as a conventional calcium carbonate filter for fair current filtering, or can conduct a better countercurrent filtering mode by opening the pump, so as to increase the fault tolerance rate of the whole system, bring out the residual bubbles in the filter and ensure working of the filter at a constant pressure; therefore, the filter can ensure the flow velocity of water and filtering effect.

Description

technical field [0001] The invention relates to the field of industrial circulating water treatment, in particular to a forward and reverse double-flow calcium carbonate filter. Background technique [0002] According to the national electric power industry standard of the existing industrial water treatment calcium carbonate filter, the water intake enters from the top and flows downstream. The disadvantage of this water inlet method is that the calcium carbonate particles in the filter are compacted during the experiment, which is easy to cause blockage of the flow path, and once a problem occurs in a certain part, it needs to be repaired before it can continue to run. The fault tolerance rate of the entire system lower. Contents of the invention [0003] The invention includes a first calcium carbonate filter column, a shell, a second calcium carbonate filter column, a water pump, a three-way diverter, a submerged elbow with a cover, a first gate valve, a second gate v...
