Abstract
The utility model provides an open-type resin exchange tower. The resin exchange tower is provided with a tower body; a feed opening is formed at the upper part of the tower body; a discharge opening is formed at the lower part of the tower body; the upper part of the tower body is open; a bracket is arranged at the open part of the tower body; a filter pillar adopting a hollow pillar body is arranged on the bracket; a plurality of filter holes are formed on the pillar body; one end of the filter pillar is connected with the feed opening; an isolation screen plate is arranged at the inner lower part of the tower body; and quartz sand is paved on the isolation screen plate. Instead of adopting the original design that wind caps are mounted in an upper sealing head and a lower sealing head, the internal structure of the resin exchange tower adopts the structure that the upper part is open, and the lower part adopts the screen plate and the quartz sand to replace the wind caps for intercepting and filtering cationic resin, so that the defects of equipment corrosion, heavy maintenance work, complex operation and short service life can be eliminated radically, the operation of the exchange tower can be completely fulfilled under a normal pressure, the safety factor is high, equipment bearing pressure is greatly reduced, the operation and the control can be conducted more visually, and resin has low probability of running off.
Description
The ㈠ technical field: the utility model relates to the chemical industry equipment field, is applied to a kind of opened type resins exchange tower of producing hypophosphorous acid operation main equipment in the sodium hypophosphite production course.
㈡ prior art: at present, in the hypophosphorous acid production process that chemical industry is used, hypophosphorous acid has been the effect of regulating sodium hypophosphite product P H value, producing sodium hypophosphite is a very main critical process, its preparation method is to adopt contrary liquid towards material also more convenient, fast, but run into suspension, during particularly with the supersaturated solution of crystalline solid, the still bottom sediments has thicker crystalline solid, this is that the ellipse spool just can not open it that to cause stream contact exchange, equipment be to adopt sealing steel lining vulcanization tower, its defective be device interior up and down cap structure damage easily, cause resin to run off, maintenance capacity is big, trivial operations, service life is short, and equipment bearing capacity under sealing state is big, safety coefficient is low, is difficult for observing and control.
The ㈢ summary of the invention: the purpose of this utility model is improved above shortcoming exactly.Propose a kind of whole tower and when operation, under normal pressure, carry out fully, the safety coefficient height, pressure of equipment power reduces and easy operation control more directly perceived and the difficult opened type resins exchange tower that runs off of resin greatly.
The utility model opened type resins exchange tower, has tower body, tower body top is provided with charging aperture, the bottom is provided with discharging opening, it is characterized in that: tower body top is uncovered, and open-mouth is provided with support, be placed with the filter post on the support, filter post one end is connected with charging aperture, and the bottom in the tower body is provided with the isolation sieve plate, isolates on the sieve plate to be covered with quartz sand.
Described opened type resins exchange tower is characterized in that: described filter post is a hollow cylinder, has several filter openings on the cylinder.
The utility model internal structure has been abandoned the design that blast cap is installed in the original upper-lower seal head, top is uncovered, the bottom utilizes sieve plate and quartz sand to replace blast cap to block and carries the filtration resin cation, can thoroughly solve equipment corrosion, maintenance capacity is big, the defective that trivial operations, service life lack can make exchange column carry out the safety coefficient height fully under normal pressure when operation, pressure of equipment power reduces greatly, and easy operation control more directly perceived and resin are difficult for running off.
The ㈣ description of drawings
Fig. 1 is that structure master of the present utility model looks schematic diagram;
Fig. 2 is that structure of the present utility model is overlooked (amplification) schematic diagram.
Among the figure, the 1-tower body, the 2-charging aperture, the 3-support, 4-filters post, and 5-isolates sieve plate, 6-quartz sand, 7-discharging opening, 8-filter opening.
The ㈤ specific embodiment:
Referring to Fig. 1, the utility model opened type resins exchange tower has tower body 1, tower body 1 top is provided with charging aperture 2, and the bottom is provided with discharging opening 7, and tower body 1 top is uncovered, open-mouth is provided with support 3, is placed with filter post 4 on the support 3, and filter post 4 is a hollow cylinder, have several filter openings 8 on the cylinder, filter post 4 one ends are connected with charging aperture 2, are used for convey materials, and the bottom in the tower body 1 is provided with and isolates sieve plate 5, isolate on the sieve plate 5 being covered with quartz sand 6, replace blast cap to block and carry the filtration resin cation.
Claims (2)
