Description
Technical Field
The utility model belongs to the technical field of filtration equipment, especially, relate to a filter water tank after water is gone out in static pressure formula papermaking plain boiled water air supporting.
Background
In the current market, an air flotation machine is generally adopted for carrying out backwater treatment in the recycling process of papermaking white water, and the air flotation machine needs to be integrally washed every 2-3 days in the recycling water treatment process. The air flotation machine is a square air flotation machine, the monitoring value of the suspended matters in the effluent water is about 2mg/l at the initial stage of production washing, the suspended matters cannot be monitored in partial time intervals, after the air flotation machine operates for 2 days, granular suspended matters are generated at the water outlet pipe of the air flotation machine, a layer of white film-shaped matters is hung on the inner wall of the water outlet pipe of DN300, the white film-shaped matters fall off after the disturbance of the effluent water quality, enter a reuse water tank along with the effluent water, and are reused after being screened. The value of the suspended substance is monitored to be between 4 and 10mg/l, although the monitored value is lower, part of the suspended substance is remained on a sizing net of a paper machine in the net punching process of the paper machine, the suspended substance is wrapped on paper surface after sizing of the paper machine, and the phenomena of bottom leakage and end breakage of a travelling crane on the paper surface after the suspended substance is dried into paper are avoided, so that the product cost rate is influenced, and the cost of waste product re-papermaking is increased. In order to reduce the influence of floating particles on the product quality, the air flotation machine needs to be integrally washed for 2 to 3 days. The method comprises the steps of emptying all white water in the air flotation machine, thoroughly cleaning the inner walls of a water inlet pipeline and a water outlet pipeline, the double surfaces of a middle inclined plate and the bottom surface of the air flotation machine by using a high-pressure cleaning machine, wherein the cleaning time is about 4 hours, at the moment, the net flushing of the paper machine can only use clean water, and the water consumption of the paper machine is increased. And after the air flotation machine finishes washing, filling clear water into the air flotation machine, adding the medicine, feeding white water into the air flotation machine for white water air flotation treatment, and stopping using the clear water after the system recovers to use the white water for treatment. Firstly, a large amount of workload is brought in the cleaning process of the air flotation machine, secondly, in the cleaning process of the air flotation machine, a paper machine needs to use clear water to wash a net, after washing is finished, the air flotation machine is filled with the clear water to start up the machine, a large amount of clear water is consumed, and a certain influence is generated on a white water recycling system.
