Description
Technical field
The utility model relates to a kind of change salt device for production of caustic soda.
Background technology
Caustic soda has two kinds of production methods: causticizing process and electrolysis.Causticizing process generates caustic soda with the soda ash aqueous solution and milk of lime by causticizing reaction; Electrolysis adopts the electrolysis saturated common salt aqueous solution to generate caustic soda, and by-product chlorine and hydrogen.Therefore, electrolysis is produced caustic soda and is also called chlorine industry.Current production of caustic soda adopts electrolysis to produce.
Changing salt operation is first step that electrolysis produces caustic soda, the light salt brine that the recovered brine sent here with evaporation section by solid crude salt (or collocation part bittern water), desalinization of soil by flooding or leaching mud reclaim, blending in proportion, heating for dissolving become the saturated aqueous solution of sodium chloride-containing.Therefore change salt device to have a very important role, traditional change salt apparatus structure is complicated, complex operation, changes salt weak effect, needs often maintenance and renewal part.
Utility model content
For the problems referred to above, the utility model proposes a kind of change salt device for production of caustic soda.
For solving this technical problem, the utility model takes following scheme: a kind of change salt device for production of caustic soda, comprise hopper, salt dissolving tank and crude brine storage tank, between hopper and salt dissolving tank, be provided with the lifting track above by the crude salt feeding salt dissolving tank in hopper, promote the track back side and be provided with the lifting device also promoting hopper; Connected by pipeline between described salt dissolving tank and crude brine storage tank, the pipeline of salt dissolving tank and crude brine storage tank is provided with delivery pump.
Further, described salt dissolving tank comprises base, base is provided with columniform staving, and staving top is the openend that crude salt enters, and is provided with iron railings outside openend, is provided with overflow launder outside openend, and overflow launder is provided with crude brine outlet; Described inner wall of barrel is provided with baffling circle and steam pipe coil, baffling circle tilts to be installed in the middle part of inner wall of barrel, put the aperture of clean remaining salt solution when offering for stopping bottom baffling circle, steam pipe coil is positioned at below baffling circle, steam pipe coil offers the fumarole of ejection steam downwards; Be provided with distributor pipe bottom described staving, distributor pipe is connected with salinated water import, distributor pipe is vertically installed with multiple outlet pipe, and outlet pipe top is provided with the baffling cap of mushroom shape.
Baffling cap is used for preventing salt grain, foreign matter etc. from entering distributor pipe resulting in blockage phenomenon, steam sprays from the fumarole of steam pipe coil, fumarole direction is downward, salt solution can be avoided to splash or steam pipe coil blocking, the effect of baffling circle avoids salt dissolving tank partial cross section flow velocity excessive or change salt solution and walk short circuit along wall and cause top crude salt to produce bridging phenomenon.The salt solution overflow launder that salt dissolving tank top is arranged and iron railings, contact the saturated crude brine risen, overflow from upper isopipe with salt deposit anti-phase, the floatability foreign matters such as the rope often carried secretly in crude salt, grass, bamboo chip stop removing through top iron railings.
Further, the angle between described baffling circle and inner wall of barrel is 40 ~ 50 °.
Further, described outlet pipe is staggered installation of the both sides at distributor pipe.
Further, the line between the described fumarole center of circle and the steam pipe coil center of circle and the angle between horizontal plane are 40 ~ 50 °.
Further, the width of described baffling circle is 150 ~ 250mm.
Further, described staving offers the manhole of easy access.
By adopting preceding solution, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, and simple to operate stable, crude salt dissolution velocity is fast, and then accelerates the speed of production of saturated crude brine.
