Abstract
This technology relates to field of fine chemical, provides the online bactericidal unit that a kind of structure is simple, can carry out online sterilizing to filter; It comprises cartridge filter, and cartridge filter filter element is interior is discharging chamber, and filter element is outer, filter housing is interior is feed cavity, also comprises the feed pipe communicated with feed cavity, the discharge nozzle communicated with discharging chamber, also comprises the vacuum pump communicated with filter feed cavity.
Description
Technical field
This technology relates to field of fine chemical, provides a kind of online bactericidal unit.
Background technology
Filter element of precision filter needs online sterilizing in process of production, and the temperature of online sterilizing is generally 121 DEG C, is equivalent to the saturated vapour pressure under 0.11MPa.When sterilizing, filter element is moistening, and the filter element after moistening can produce moisture film, and the pure steam under right 0.3MPa all cannot penetrate filter element.Therefore online sterilizing is not thorough.
Summary of the invention
The object of this technology is to provide the online bactericidal unit that a kind of structure is simple, can carry out online sterilizing to filter.
The online bactericidal unit of the one provided in this technology is achieved through the following technical solutions:
This online bactericidal unit, comprises cartridge filter, and cartridge filter filter element is interior is discharging chamber, and filter element is outer, filter housing is interior is feed cavity; Also comprise the feed pipe communicated with feed cavity, the discharge nozzle communicated with discharging chamber; Also comprise the vacuum pump communicated with filter feed cavity.
The beneficial effect of this online bactericidal unit is:
Start vacuum pump evacuation, the steam of filter element is first drawn out of, only remaining aqueous water.Along with the increase of vacuum, in filter housing, absolute pressure reduces, when the absolute pressure in filter housing is reduced to the saturation vapor pressure corresponding with ambient temperature, water remaining in filter housing is boiled into steam, extracted out by continuation, eliminate the moisture film produced in filter element, make steam can penetrate filter element to discharging chamber, to the online sterilizing of filter element.
As the improvement to this online bactericidal unit, vacuum meter is set before vacuum pump and communicates with vacuum pump.
The online sterilization process of the one provided in this technology is achieved through the following technical solutions:
This online sterilization process, comprises the following steps:
Feed liquid in a, emptying filter and pipe-line system and moisture;
B, in filter, be filled with saturated vapor by feed pipe;
C, some vapor are discharged by discharge nozzle;
D, startup vacuum pump evacuation;
E, repetition step b-d.
The beneficial effect of this online sterilization process is:
By the feed liquid in filter and pipe-line system and moisture emptying put clean, for online sterilizing provides good activity bases.
Open feed pipe discharge nozzle, in filter, be filled with saturated vapor by feed pipe, feed cavity is carried out to sterilizing, carried out short time sterilizing to filter element, and some vapor is discharged by discharge nozzle; Meanwhile, in filter element, part steam coagulation is aqueous water, in filter element, form moisture film, intercepts vapor transmission filter element and enters discharging chamber.
Close feed pipe, discharge nozzle, start vacuum pump evacuation, the steam of filter element is first drawn out of, only remaining aqueous water.Along with the increase of vacuum, in filter housing, absolute pressure reduces, when the absolute pressure in filter housing is reduced to the saturation vapor pressure corresponding with ambient temperature, water remaining in filter housing is boiled into steam, extracted out by continuation, eliminate the moisture film produced in filter element, make steam can penetrate filter element to discharging chamber, to the online sterilizing of filter element.
Through repeatedly repeating, to filter and pipe-line system thoroughly online sterilizing.
Accompanying drawing explanation
Fig. 1 is the structural representation of this online bactericidal unit.
Detailed description of the invention
Below in conjunction with accompanying drawing, this technology is described further:
This online bactericidal unit shown in Figure 1, comprises cartridge filter, is discharging chamber 5 in cartridge filter filter element 4, is feed cavity 3 outside filter element 4, in filter housing 8; Also comprise the feed pipe 1 communicated with feed cavity 3, the discharge nozzle 2 communicated with discharging chamber 5; Also comprise the vacuum pump 7 communicated with filter feed cavity 3.Before vacuum pump 7, arrange vacuum meter 6 communicate with vacuum pump 7.
Feed pipe 1 and discharge nozzle 2 are all in series with valve (not shown), immediately to open, to close feed pipe 1 and discharge nozzle 2 as required.
Vacuum pump 7 is arranged on above cartridge filter, is connected with filter with fast-assembling chuck.
The object arranging vacuum meter 6 observes filter housing 8 internal vacuum situation.The range of vacuum meter 6 is 0.1 ~ 0MPa, temperature :-40 DEG C ~ 70 DEG C.
The online sterilization process using above-mentioned online bactericidal unit to carry out online sterilizing comprises by following steps:
A. the feed liquid in emptying filter and pipe-line system and moisture.By the feed liquid in filter and pipe-line system and moisture emptying put clean, for online sterilizing provides good activity bases.
B. in filter, saturated vapor is filled with by feed pipe.Open feed pipe discharge nozzle, in filter, be filled with saturated vapor by feed pipe, feed cavity is carried out to sterilizing, carried out short time sterilizing to filter element, and some vapor is discharged by discharge nozzle; Meanwhile, in filter element, part steam coagulation is aqueous water, in filter element, form moisture film, intercepts vapor transmission filter element and enters discharging chamber.
C. some vapor is discharged by discharge nozzle.
D. vacuum pump evacuation is started.Close feed pipe, discharge nozzle, start vacuum pump evacuation, the steam of filter element is first drawn out of, only remaining aqueous water.Along with the increase of vacuum, in filter housing, absolute pressure reduces, when the absolute pressure in filter housing is reduced to the saturation vapor pressure corresponding with ambient temperature, water remaining in filter housing is boiled into steam, extracted out by continuation, eliminate the moisture film produced in filter element, make steam can penetrate filter element to discharging chamber, to the online sterilizing of filter element.
E. step b-d is repeated.Through repeatedly repeating, to filter and pipe-line system thoroughly online sterilizing.
The beneficial effect of this technology is:
Use above-mentioned online bactericidal unit, can realize preferably for filter and pipe-line system thoroughly online sterilizing.
