Description
Technical field
The utility model belongs to connection alkali production technical field, is specifically related to connection alkali production Recycling Mother Solution system.
Background technology
Connection alkali is produced with the closed cycle of mother liquor system, says theoretically, should without discharging of waste liquid.But major part alkaline enterprise of China is because joining alkali system, corrosive pipeline seriously, and production technique fluctuation causes greatly mother liquor to expand, connection alkali industry is caused to occur discharging of waste liquid phenomenon.Environmental protection is carried out in the current whole nation, energy-saving and emission-reduction action, so connection alkali industry must reduce or stop discharging of waste liquid.It is realize mother liquor to shrink or balance at all, could solve discharging of waste liquid, realize the phenomenon of discharging of waste liquid zero.
Connection alkali the systematic stock solution balance is the key factor of puzzlement production long period smooth running always, and the key factor maintaining mother liquor balance is exactly reduce the water consumption of the heavy alkali of filtration of bicarbonate workshop section washing, reduces wash water equivalent.And the key factor affecting the factor of wash water equivalent is exactly the solid-to-liquid ratio going out alkali lye after improving carbonating, and traditional technology uses thickener solid-to-liquid ratio can only be increased to about 20%, if solid-to-liquid ratio is increased to more than 60%, add magma rinse high solid-liquid ratio go out alkali lye after enter filter station, can greatly reduce wash water consumption, and then maintain mother liquor balance.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of connection alkali production Recycling Mother Solution system, improves solid-to-liquid ratio, reduces wash water consumption, maintain mother liquor balance.
The technical solution adopted in the utility model is: a kind of connection alkali production Recycling Mother Solution system, comprise belt Alkali-filter, the liquid phase outlet of belt Alkali-filter is connected with separator, and the liquid-phase outlet of separator is connected with filtrate pipe, and filtrate pipe is connected with secondary wash water bucket, mother liquor settling tank; Secondary wash water bucket is connected with wash water pump, wash water pump is connected with washing magma pipe, and washing magma pipe is connected with swirler, one-level base output trough, secondary base output trough, and the clear liquid pipe of swirler is connected with thickener, thickener is connected with one-level base output trough, mother liquor settling tank, and mother liquor settling tank is connected with mother vat.
Described secondary wash water bucket is provided with liquidometer.
Described washing magma pipe two is provided with knife gate valve.
The beneficial effects of the utility model are: bring up to more than 85% by going out alkali lye magma solid-to-liquid ratio by original 15%--25%, alleviate thickener load, directly gone by original mother liquor thickener to use belt Alkali-filter filtrate to wash to mother liquor I bucket simultaneously and be diluted to 45%--55% for filtration rotary drum Alkali-filter, belt Alkali-filter normally.Thus reach magma washing, to reduce wash water consumption 80-100kg/ ton gently grey, and can stablize light grey salinity, the systematic stock solution is shunk, the chlorine-contained wastewater direct subsidy system that connection alkali produces, reduces the consumption such as steam, salt consumption, thus reach effects such as joining alkali waste water zero release.

Embodiment
Below in conjunction with embodiment accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of connection alkali production Recycling Mother Solution system, comprise belt Alkali-filter 6, the liquid phase outlet of belt Alkali-filter 6 is connected with separator 5, the liquid-phase outlet of separator 5 is connected with filtrate pipe 11, and filtrate pipe 11 is connected with secondary wash water bucket 9, mother liquor settling tank 7; Secondary wash water bucket 9 is connected with wash water pump 10, wash water pump 10 is connected with washing magma pipe 3, washing magma pipe 3 is connected with swirler 1, one-level base output trough 4, secondary base output trough, the clear liquid pipe of swirler 1 is connected with thickener 2, thickener 2 is connected with one-level base output trough 4, mother liquor settling tank 7, and mother liquor settling tank 7 is connected with mother vat 8.
Secondary wash water bucket 9 is provided with liquidometer.
Washing magma pipe 3 two is provided with knife gate valve 12, controls washing magma and removes one-level, secondary base output trough.
Principle of work: connection alkali the systematic stock solution and conversion gas in carbonating tower after carbonation reaction go out alkali lye principle of thickening in swirler be utilize swiftly flowing go out alkali lye enter into swirler, improve the solid-to-liquid ratio content alkali lye (sodium bicarbonate) according to centripetal force action principle.The alkali lye (sodium bicarbonate) that goes out that the mother liquor that chloride ion-containing after simultaneously utilizing filter station to wash heavy alkali is low is high to the chloride ion-containing after thickening rinses, and reduces the heavy neutralizing treatment water consumption of filter progress, maintains mother liquor balance.
Working process: enter gas-liquid separator 5 from belt Alkali-filter 6 gas-liquid mixture out, the filtrate pipe 4 that gas-liquid separator 5 connects adds DN150 valve, connect a pipeline to secondary wash water bucket 9 and on bucket, increase liquidometer and with self-adjusting valve control filtrate carry out stable liquid level, utilize secondary wash water pump 10, get to washing magma pipe with pipeline and connect on swirler magma pipeline and do washings, the clear liquid gone out from swirler 1 enters in thickener 2, in thickener 2, suspended emulsion enters one-level base output trough 4, clear liquid enters mother liquor settling tank 7, finally enters mother vat 8; Magma pipeline below swirler 1 adding DN80 valve can the size of manipulated variable, and make a funnel below and receive magma sluicing pipe 3 to connect magma, and increase by two knife gate valves 12 at magma sluicing pipe 3 two and control washing magma one-level, secondary base output trough, got back in belt Alkali-filter 6 by one-level base output trough 4.
