Description
One, technical field
The present invention relates to a kind of toilet, especially trace element and isotope analysis are with the clean chamber of earning of acid-proof.
Two, background technology
The purposes of toilet is more and more many, as the detection of preparation, trace and the trace element of high-purity material, have a wide range of applications in industries such as electronics, biology, pharmacy.The dustless environment of high-tech product needed guarantees its quality; Need such toilet during detection, toilet and clean bench are removed particulate, carry out air filtration.Purification rank as existing superclean bench reaches 100 grades, mean wind speed (M/S): 0.2-0.4, but workspace size (mm) is less: 870*500*450.The air of operational zone high-cleanness, high working environment can only be provided.This equipment adopts horizontal or vertical one-way air stream, and room air enters plenum chamber through prefilter, passes through high efficiency particle air filter again, the last vertical one-way air stream that forms high cleaning in the operational zone.Other has the cleaning ambient of high level and good operability as biological superclean bench, and compact structure and certain work space are provided.Filtering material adopts low step-down HEPA filtrator (0.3 μ m particle, 99.99% dust catching efficiency) to provide clean air to the workspace.Toilet's cost height in existing big zone, the design of air cleaning system may not be reasonable, and difficulty satisfies high-grade standard. and especially in electronics, biology, pharmaceutical field, generally adopt metal material can not satisfy the standard of high-grade inorganic elements and isotope analysis in the toilet.
Three, summary of the invention
The object of the invention is: a kind of toilet that big zone can be provided is provided, satisfy acceptance specification JGJ71-90, and has an anti-acid function of chemistry, satisfy the requirement of high precision apparatus measures, comprise and carry out micro-example trace element and isotope analysis, the individual particle zircon is analyzed, and also is used for the preparation toilet of various inorganic and organic physico-chemical analysis and high-purity material.
The present invention seeks to realize like this: the toilet is a zone of positive pressure, its supply and exhaust situation: all enter the wind in ultra-clean district through behind the three-stage filtration, air intake duct is provided with serial low efficient filter and medium effeciency filter, deliver in the plenum chamber in each room through trunk line then, indoor through the defeated people of high efficiency particulate air filter again, each chamber rate of ventilation reach 50 times/per hour, make each chamber under main air blower or blower fan duty on duty, can both reach indoor malleation.Other is provided with the circulation return air duct, the air of indoor nontoxic no acid gas is sent into the blast main road again from return air duct, be used to save the energy that input air freezes or heats, reducing the consumption of purification filtering material and reduce operating cost. high efficiency particulate air filter is failed the indoor and worktable of people, be provided with sucktion fan in the clean work station space, all directly discharge the harmful gases such as waste gas of worktable outdoor, thereby can guarantee the physical and mental health of combustion gas support personnel when experiment like this, each clean room air quantity configuration suitably reaches designing requirement.
The decontamination chamber is under the primary air fan duty, and noise is the 47-53 decibel, and under the machine duty, noise is the 42-48 decibel on duty.
Further improvement of the present invention also comprises: all enter to flow back to the airduct road and all adopt plastic conduit.Indoor purifying worktable, ventilation toxin-expelling cabinet and experimental work table top all adopt plastic plate, acrylic plastering sheet material especially, and it is compared with traditional polyvinyl chloride plastic plate, and acrylic plastering sheet material has environmental protection, nontoxic, and is high temperature resistant.Decontamination chamber's metope and end face adopt double applying face polyamine alkene high-density plate.Acrylic plastering sheet material and high-density plate all have acid-proof, alkali prevention, heatproof and smooth characteristics.The epoxy resin self-leveling terrace is adopted on ground, decontamination chamber.
Characteristics of the present invention are: a kind of toilet that big zone can be provided is provided, and chemical acid-proof anti-corrosion function arranged, satisfy the requirement of apparatus measures, comprise and carry out trace element and isotope analysis, the individual particle zircon is analyzed, and also is used for the preparation toilet of various inorganic and organic physico-chemical analysis and high-purity material.The superclean bench cleanliness factor, contain in every cubic foot of air 〉=0.5 μ m grit number is lower than 30 after testing, and (GBJ73-84) is better than 100 grades by China's Code for design of industrial clean rooms, adheres to specification.The purification cleanliness factor in 2 districts and 3 districts: contain in every cubic foot of air 〉=0.5 μ m grit number is lower than 150, is better than 1000 grades by standard, adhere to specification.The purification cleanliness factor in 4 districts and 5 districts: contain in every cubic foot of air 〉=0.5 μ m grit is lower than 400, is better than 4000 grades by standard, adhere to specification.Earning rank between passageway and buffering be contain in every cubic foot of air 〉=0.5 μ m grit is lower than 1900, is better than 5000 grades by standard, adhere to specification.The waste gas of worktable is all directly discharged outdoor, thereby can guarantee the physical and mental health of combustion gas support personnel when experiment like this, each clean room air quantity configuration is suitable.Integrated poured epoxy gravity flow level ground does not have seam, and no electrostatic precipitation meets the purification Laboratory Request.Meet decontamination chamber's standard.Especially all right angles all adopt R angle circular arc plastics junctor in the acid-proof decontamination chamber, reduce to greatest extent to purify dead angle area; Between newly-designed dressing cubicle and buffering is one, has the effect of Airshower chamber, easy to use, saves the energy, reduces construction costs: in clean bench,, the brightness of clean bench is obviously improved by having adorned the Philip corrosion-proof luminaire, and easy to operate; In dressing cubicle, have health drip washing chamber concurrently, make the staff improve self cleaning, guaranteed indoor cleanliness factor.In addition,, closely link to each other, also guaranteed the certain cleanliness factor between instrument with purifying area though the instrument room belongs to non-purifying area, rationally distributed, have good peripheral greening environment.The decontamination chamber is under the primary air fan duty, and noise is the 47-53 decibel, and under blower fan duty on duty, noise is the 42-48 decibel.The design of blower fan on duty can be saved the barotropic state that energy guarantees the chamber.
