Abstract
The invention discloses a circulating device of pure water in concentrated production of caustic soda and caustic soda flakes. The circulating device comprises a pure water pipeline and pure water using equipment, wherein the pure water pipeline conveys pure water to a pure water collecting tank through a pure water inlet pipe, the pure water collecting tank is provided with a pure water circulating water pump which pumps pure water in the pure water collecting tank out and conveys pure water to a pure water head tank through a pure water outlet pipe, the discharge outlet of the pure water head tank is connected with a pure water discharge pipe, the installation height of the pure water head tank guarantees that pure water in the pure water head tank is naturally discharged to the pure water using equipment to be used by the pure water using equipment through a pure water discharge pipe, and pure water used by the pure water using equipment is discharged to the pure water collecting tank through a pure water return pipe. The circulating device disclosed by the invention has the advantages that pure water is continuously recycled, so that not only is the water resource saved, but also the production cost in concentration of caustic soda and caustic soda flakes is greatly lowered.
Description
Technical field
The present invention relates to caustic soda, the concentrated production technical field of sheet alkali, be specifically related to the emission treatment of pure water in caustic soda, the concentrated production of sheet alkali.
Background technology
In multiple production unit in caustic soda, the concentrated production of sheet alkali, need to use pure water, these equipment are referred to as pure water and use equipment, as: alkali pump, vacuum pump etc., it is cooling that alkali pump need to be used pure water to carry out its mechanical seal, and vacuum pump need to use pure water as working fluid water.At present, pure water use equipment is used pure water to be later directly disposed to trench, thereby causes great lot of water resources waste, has also greatly increased caustic soda, the concentrated production cost of sheet alkali simultaneously.
Summary of the invention
The object of the invention is: provide a kind of and can make full use of the caustic soda of pure water, saving water resource, the circulation device that sheet alkali concentrates pure water in production.
For achieving the above object, the technical solution used in the present invention is: caustic soda, the circulation device of pure water in the concentrated production of sheet alkali, comprise: pure water pipe network and pure water are used equipment, DI Netcom crosses pure water water inlet pipe pure water is delivered in pure water collection groove, on pure water collection groove, be provided with pure water water circulating pump, pure water water circulating pump pumps the pure water in pure water collection groove, and be delivered in pure water header tank by pure water rising pipe, on the discharge outlet of pure water header tank, be connected with pure water delivery pipe, the mounting height of pure water header tank guarantees that the pure water in pure water header tank is disposed in pure water use equipment naturally by pure water delivery pipe, for pure water equipment, use, pure water use equipment is used pure water to be later disposed in pure water collection groove by DIR.
Further, aforesaid caustic soda, sheet alkali are concentrated produce in the circulation device of pure water, wherein, pure water water circulating pump pumps the pure water in pure water collection groove and is first delivered to after cooling in water cooler and is delivered in pure water header tank again by pure water rising pipe.
Further, the circulation device of pure water in aforesaid caustic soda, the concentrated production of sheet alkali, wherein, described water cooler is plate cooler.
Further, aforesaid caustic soda, sheet alkali are concentrated produce in the circulation device of pure water, wherein, pure water collection groove is arranged on below ground level, the mounting height of pure water header tank is not less than 11 meters and not higher than 18 meters.
Advantage of the present invention is: allow pure water constantly recycle, both saved water resources, greatly reduce again caustic soda, the concentrated production cost of sheet alkali.
Accompanying drawing explanation
Fig. 1 is the structural representation of the circulation device of pure water in the concentrated production of caustic soda of the present invention, sheet alkali.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the present invention is described in further detail.
As shown in Figure 1, caustic soda, the circulation device of pure water in the concentrated production of sheet alkali, comprise: pure water pipe network 1 and pure water are used equipment 9, pure water pipe network 1 is delivered to pure water in pure water collection groove 3 by pure water water inlet pipe 2, on pure water collection groove 3, be provided with pure water water circulating pump 4, pure water water circulating pump 4 pumps the pure water in pure water collection groove 3, and be delivered in pure water header tank 7 by pure water rising pipe 5, on the discharge outlet 71 of pure water header tank 7, be connected with pure water delivery pipe 8, the mounting height of pure water header tank 7 guarantees that the pure water in pure water header tank 7 is naturally disposed to pure water by pure water delivery pipe 8 and uses in equipment 9, for pure water equipment 9, use, pure water is used equipment 9 to use pure water to be later disposed in pure water collection groove 3 by DIR 10.In the present embodiment, pure water water circulating pump 4 pumps the pure water in pure water collection groove 3 and is first delivered to after cooling in plate cooler 6 and is delivered in pure water header tank 7 again by pure water rising pipe 5.In order to make full use of potential energy, reduction equipment use cost, in the present embodiment, pure water collection groove 3 is arranged on below ground level, and the mounting height of pure water header tank 7 is not less than 11 meters and not higher than 18 meters, the mounting height that test of many times obtains pure water header tank 7 be arranged on 14.5 meters of be most economical rationally.
Principle of work is as follows: pure water pipe network 1 is delivered to pure water in pure water collection groove 3 by pure water water inlet pipe 2, water level in pure water collection groove 3 reach pure water collection groove 3 height 75% time, start pure water water circulating pump 4, pure water water circulating pump 4 by the pure water in pure water collection groove 3 by pure water rising pipe 5 be first delivered to cooling in plate cooler 6 after, be delivered to again in pure water header tank 7, because pure water header tank 7 has enough potential energy, pure water in pure water header tank 7 is naturally disposed to pure water by pure water delivery pipe 8 and uses in equipment 9, for pure water equipment 9, use, pure water is used equipment 9 to use pure water later by DIR 10, to be disposed in pure water collection groove 3 again, thereby constantly circulation.In order to prevent that pure water temperature in above-mentioned working cycle from raising, be therefore provided with plate cooler 6,6 pairs of pure water of plate cooler carry out cooling, thereby have guaranteed the normal circulation of pure water and effectively used.
The invention has the advantages that: allow pure water constantly recycle, both saved water resources, greatly reduce again caustic soda, the concentrated production cost of sheet alkali.
