Technical Field
The utility model belongs to the technical field of pulping and papermaking, and particularly relates to a vacuum exhaust condensation water-saving system of a green mud filter.
Background
The green mud filter is vacuumized by a vacuum pump, and the filtering function is realized by the pressure difference. The gas extracted from the green mud filter contains moisture and pollution components, and the gas needs to be cooled by a high-level condenser to remove part of the moisture before entering the vacuum pump. The high-order condenser has the function of directly contacting the gas by the sprayed normal-temperature clean water, so that the moisture in the gas is cooled and condensed. However, as the capacity increases, the amount of water required becomes greater. In addition, since not only moisture is condensed but also a part of soluble pollutants are dissolved in water during the condensation of the gas, a large amount of sewage is formed. The drainage of the high-level condenser is generally discharged into a sewage treatment plant, and the sewage treatment requires cost and increases the pressure of the sewage treatment plant. Therefore, the current vacuum exhaust condensing system of the green mud filter has the problems of large water consumption and large sewage discharge.

The liquid outlet 23 at the bottom of the high-level condenser 2 is connected with a liquid discharge pipeline 24, the bottom end of the liquid discharge pipeline 24 is positioned in a water seal pool 6, and the water seal pool 6 is connected with a medium sewage condensate water pipeline 61 of an evaporation section. The circulating heat exchange device 4 comprises a heat exchanger 41 and a circulating pump 42, the heat exchanger 41 comprises a shell 411 and a heat exchange coil 412 positioned in the shell 411, cooling water is arranged in the shell 411, and the side wall of the shell 411 is respectively connected with a cooling water inlet pipe 43 and a cooling water outlet pipe 44. The inlet of the heat exchange coil 412 is located at the lower part of the housing 411 and is connected to the outlet of the circulation pump 42 through a third pipe 53, and the inlet of the circulation pump 42 is connected to the water-sealed tank 6 through a fourth pipe 54. The outlet of the heat exchange coil 412 is located in the upper portion of the housing 411 and is connected to the liquid inlet 25 at the top of the high-level condenser 2 by a fifth line 55.
In order to prevent the liquid level in the water-sealed tank 6 from being too high, a sixth pipeline 56 with a drain valve 57 is connected to the middle of the third pipeline 53, and the tail end of the sixth pipeline 56 is connected to the heavy-sewage condensate tank 7 of the evaporation section so as to drain the excessive sewage in the water-sealed tank 6 into the heavy-sewage condensate tank 7 of the evaporation section.

Specifically, the working flow of the vacuum exhaust condensation water-saving system of the green mud filter is as follows:
first, the medium-sewage condensed water of the evaporation section is supplemented to the water seal tank 6 through the medium-sewage condensed water pipeline 61, and the advantage is that the medium-sewage condensed water is softened water and is not easy to scale. Secondly, the middle-sewage condensed water is cooled to 43 ℃ through the heat exchanger 41, the spray water sprayed in the high-level condenser 2 returns to the water seal tank 6 again, the spray water and the middle-sewage condensed water after temperature rise are cooled to 43 ℃ through the heat exchanger 41 again by using the circulating pump 42, so that the spray is circulated, and the use amount of the middle-sewage condensed water in the clean water and the evaporation section is reduced. In addition, through the liquid level linkage, the liquid level of the water seal pool 6 is controlled by using the sixth pipeline 56 and the blow-down valve 57 thereof, and when the liquid level is high, sewage is conveyed to the heavy sewage condensation water tank 7 of the evaporation section, so that the sewage is prevented from being discharged into a sewage treatment field, and the sewage treatment cost is reduced.
