Abstract
The utility model discloses a buffer solution charging device which comprises at least one first reaction kettle and at least one second reaction kettle, wherein the bottom of the first reaction kettle is connected with a first valve; the first valve is connected with a third pump; the discharge opening of the third pump is connected with a process pipeline; the bottom of the second reaction kettle is respectively connected with a second valve and a third valve; the second valve is connected with the first pump; the discharge opening of the first pump is connected with the top of the second reaction kettle; the third valve is connected with the second pump; and the discharge opening of the second pump is connected with the process pipeline. The buffer solution system is configured through two reaction kettles, the flow is accurately controlled through the metering pump, the preparation of a buffer solution for the operators is convenient, and the raw material waste is reduced.
Description
Technical field
The utility model relates to a kind of buffer solution feeding device, belongs to the chemical industry equipment field.
Background technology
Buffer solution feeding device of the prior art all is a reactor usually, namely the raw material of the raw material of solid and the liquid certain concentration of furnishing behind the mixed dissolution according to a certain percentage, place standbyly then, when technical process needs sort buffer liquid, just be pumped in the process pipeline with delivery pump, come the pH value of conditioned reaction thing with buffer solution, this method is because allotment is fairly simple, and equipment is relatively saved, so be widely used, but there is following defective in this method:
Switch when needing the change buffer solution if 1 relates to technology, the remaining buffer solution that configures just can not reuse, and can only be to place or drain, and has so just caused the waste of resource of leaving unused of equipment, serious, the buffer solution of discharge also pollutes the environment.
2, because the raw material of liquid and the raw material of solid all are to put in the reactor, the people who operates is had relatively high expectations, will cause the error that feeds intake in an unguarded moment, influence the effect of buffer solution.
The utility model content
The utility model is at the deficiencies in the prior art, and purpose is to provide a kind of buffer solution feeding device, can reduce raw-material loss, improves the reinforced accuracy of buffer solution.
The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of buffer solution feeding device, comprise at least one first reactor and at least one second reactor, first reactor bottom connects first valve, and first valve connects No. three pumps, and the discharging opening of No. three pumps connects process pipeline; The bottom of second reactor is connected with second valve and the 3rd valve respectively, and described second valve connects a pump, and the discharging opening of a pump connects the top of second reactor, and described the 3rd valve connects No. two pumps, and the discharging opening of No. two pumps connects process pipeline.
As the further setting of such scheme, also be provided with a chuck on described second reactor, described chuck bottom is provided with drain valve.
As the further setting of such scheme, a described pump is turbine pump.
As the further setting of such scheme, described No. two pumps and No. three pumps are measuring pump.
The beneficial effects of the utility model are: the utility model disposes buffer solution system by two reactors, and accurately controls flow by measuring pump, has made things convenient for the configuration of operating personnel for buffer solution, has also reduced the waste of raw material simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: first reactor 1, second reactor 2, first valve 3, second valve 4, the 3rd valve 5, drain valve 6, pump 7, No. two pumps 8, No. three pumps 9, chuck 21.
The specific embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of buffer solution feeding device comprises that at least one first reactor 1 and at least one second reactor, 2, the first reactors, 1 bottom connect the discharging opening connection process pipeline that first valve, 3, the first valves 3 connect 9, No. three pumps 9 of No. three pumps; The bottom of second reactor 2 is connected with second valve 4 and the 3rd valve 5 respectively, described second valve 4 connects a pump 7, the discharging opening of a pump 7 connects the top of second reactor 2, and the discharging opening that described the 3rd valve 5 connects 8, No. two pumps 8 of No. two pumps connects process pipeline.
Also be provided with a chuck 21 on described second reactor 2, described chuck 21 bottoms are provided with drain valve 6.
A described pump 7 is turbine pump.
Described No. two pumps 8 and No. three pumps 9 are measuring pump.
The course of work of the present utility model is: the buffer raw material of liquid is put in first reactor 1, and the buffer raw material of solid is put in second reactor 2; Because the buffer raw material of solid is because second reactor, 2 bottoms are sunk in the insufficient meeting of dissolving, only need close the 3rd valve 5 this moment, open second valve 4, start pump 7 No. one, buffer solution is back to second reactor, 2 tops from second reactor, 2 bottoms, play the effect of a stirring, the dissolving of accelerating solid buffer raw material; After dissolving is finished, close pump 7 No. one, open the 3rd valve 5, start pump 8 No. two, because No. two pumps 8 are measuring pumps, therefore can control flow accurately, in like manner, open first valve 3, starting 9, No. three pumps 9 of No. three pumps also is measuring pump, can control flow accurately equally; The buffer solution that pump this moment from reactor 1 and No. two reactors 2 has been formed a complete buffer solution system and has been entered process pipeline, has realized adjusting and control to the pH value of explained hereafter.
When needs accelerate the dissolution velocity of the buffer raw material in second reactor 2, can in chuck 21, feed steam, the raw material in second reactor 2 is heated, accelerate its dissolution velocity.
When needs exchange buffering liquid, if only need change raw material in one of them reactor the time, the raw material in another reactor still can continue to put in the production application, has improved utilization ratio of raw materials thus.
