Description
Technical field
The invention belongs to high purity reagent production equipment technical field, it is related to a kind of drying device of high purity reagent production line adsorbent.
Background technology
, it is necessary to be used as adsorbent using the resin of water content≤1% in high purity reagent production process.Because commercially available resin water content is 50% ~ 60%, and resin can be reused by regenerating,, it is necessary to which substantial amounts of concentration is 6-10% sodium hydroxide lyes and ultra-pure water is regenerated and cleaned in resin regeneration process, the resin water content 60 ~ 70% after regeneration washing.Such high water content, it is impossible to the requirement of high purity reagent production line is met, accordingly, it would be desirable to which resin is dried.But, the maximum temperature that resin is resistant to is 60 DEG C, and 60 DEG C of dryings can not be by the moisture removal in resin, and during 60 DEG C of temperature ＞, resin occurs degraded and eventually loses suction-operated.In addition, the carbon dioxide in air can cause resin " poisoning " and fail, therefore, resin needs isolation air, low temperature in the drying process（60 DEG C of ＜）Under the conditions of carry out.
In high purity reagent production process, in addition it is also necessary to use the molecular sieve of water content≤1% as adsorbent., it is necessary to regenerate after molecular sieve adsorption saturation, traditional regeneration is to be carried out with 250 DEG C of high pure nitrogen for a long time（About 8 ~ 12 hours）Purging, regeneration equipment making requires higher, and regenerative process is more complicated, and energy consumption is higher, therefore, and regenerating molecular sieve cost is higher.If the molecular sieve of failure is directly scrapped, the pollution of environment and the waste of resource can be caused.
The content of the invention
The present invention is in the prior art, resin, which is dried, needs isolation air, low temperature（60 DEG C of ＜）Under the conditions of carry out, regenerating molecular sieve complex process, cost be higher, the problems such as directly scrap pollution environment, cause the wasting of resources there is provided a kind of high purity reagent production line adsorbent drying device, the device is mainly by heat-conducting oil furnace heating system（1）, convolution drier（2）, vacuumize unit（3）, nitrogen storage tank（4）Deng four parts composition.Heat-conducting oil furnace heating system（1）With convolution drier（2）Pass through conduction oil flowline（8）, conduction oil oil return pipe（7）Connection, passes through conduction oil oil pump（9）The conduction oil of design temperature be would be heated in convolution drier（2）Heating jacket（15）Inside follow bad flowing.Circle round drier（2）Right side is provided with vacuum suction head（22）, vacuum suction head（22）It is bent upwards in 90 °.Vacuum suction head（22）Overhang the vacuum-pumping tube come（16）With vacuumizing unit（3）It is connected, in vacuum-pumping tube（16）On vacuum meter is installed（17）.In convolution drier（2）With vacuumize unit（3）Connected vacuum lead（16）On have nitrogen inlet valve（19）, nitrogen inlet valve（19）And nitrogen storage tank（4）Nitrogen outlet（20）It is connected, in nitrogen inlet valve（19）The nitrogen pipeline of front end（18）On nitrogen stream gauge is installed（21）.Circle round drier（2）It is a sealing, the tapered pressure container of inwall polishing, there is manhole upper end（10）, manhole（10）On have inlet valve（12）And thermometer（13）, lower end is discharging opening（14）.Circle round drier（2）Outer wall has heating jacket（15）And heat-insulation layer（14）, circle round drier（2）Installed in a support（5）On.Dry adsorbent will be needed（6）（Resin or molecular sieve）From convolution drier（2）Charging aperture（10）It is added to convolution drier（2）In, close convolution drier（2）In charging aperture（10）And discharging opening（11）, open heat-conducting oil furnace heating system（1）, open pumped vacuum systems（3）, open nitrogen storage tank（4）Nitrogen outlet valve（20）And nitrogen pipeline（18）On nitrogen inlet valve（19）, heat-conducting oil heating temperature and nitrogen flow are set in designated value, adsorbent（6）（Resin or molecular sieve）Realize and dried under conditions of negative pressure, low temperature, nitrogen protection.Adsorbent（6）Dry after finishing, close heat-conducting oil furnace heating system（1）, close vacuum pump set（3）, circle round drier（2）It is interior to normal pressure（0.1Mpa）Afterwards, convolution drier is opened（2）Lower end discharging opening（11）, the adsorbent of completion will be dried（6）Dispense on request.
Heat-conducting oil furnace heating system（1）By electrical heating heat-conducting oil heating to design temperature, pass through Heat-transfer Oil Pump（9）The conduction oil for being heated to design temperature is delivered to convolution drier（2）Heating jacket（15）, heating convolution drier（2）It is interior to need dry adsorbent（6）；Vacuumize unit（3）Pass through the drier that circles round（2）Interior vacuumizes suction nozzle（22）, take convolution drier away（2）Interior air, moisture and other solvents, it is ensured that convolution drier（2）Under 25kPa negative pressure state, low temperature, intermittent drying adsorbent（6）；Vacuum-pumping tube（16）On nitrogen pipeline（18）And nitrogen storage tank（4）, it is ensured that adsorbent is in isolation air（Nitrogen is protected）Operating mode under dry.
In above-mentioned technical proposal, resin only need to completely cut off air under 25kPa negative pressure state（Nitrogen is protected, nitrogen flow 1L/s）, 30 DEG C dry 30 minutes, you can reach the use requirement of high purity reagent production line, prevented the possibility failed in resin drying process.
In above-mentioned technical proposal, molecular sieve only need to completely cut off air under 25kPa negative pressure state（Nitrogen is protected, nitrogen flow 2L/s）, 250 DEG C dry 120 minutes, the use requirement of high purity reagent production line is can reach, regenerating molecular sieve cost is greatly reduced, molecular sieve recycling is realized, high purity reagent production cost is reduced, the waste for scrapping environmental pollution that molecular sieve causes and resource is eliminated.
