Abstract
Description
The present invention relates to a highly functional glove box high purity nitrogen generator, and more particularly, to a highly functional glove box high purity nitrogen generator for supplying high purity nitrogen to a glove box.
[C0212668], Research Project Name: Industry-Academia Collaboration Technology Development Project, Research Title: High Performance Anti-corrosion Glove Box Development.
A glove box is an experimental box used to handle substances in a box by placing the substance in a transparent box, blocking it from the room atmosphere, and putting a hand on the glove that rests on the front or side of the box. In a glove box handling radioactive materials, the air inside the box does not come out to the outside, even though the inside of the box is under negative pressure and the air in the room gets into the box from the gap.
Conventional glove boxes used in schools and national laboratories must purchase expensive high purity inert gases such as nitrogen and argon from special gas companies in order to maintain high inert conditions and use a separate nitrogen supply device outside the glove box Therefore, the maintenance cost is high and an external space is required for installing a separate nitrogen supply device.
Therefore, if a highly functional glove box high purity nitrogen generator capable of supplying nitrogen gas integrally mounted in a glove box is developed, it will be very useful in terms of cost reduction and space utilization.
It is also pointed out that it is necessary to develop a nitrogen generating apparatus of high purity which can more remarkably remove water and particles in the air than the conventional nitrogen generating apparatus.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a glove box integrated high-purity nitrogen generating apparatus provided inside a lower portion of a glove box body to supply high purity nitrogen to a glove box.
It is another object of the present invention to provide a glove box-integrated high purity nitrogen generating apparatus capable of remarkably removing moisture and particles in the air in two steps.
In order to accomplish the above object, the present invention provides a highly functional glove box high purity nitrogen generating device for supplying high purity nitrogen to a glove box, comprising: An air compressor section; A drain separator for discharging the moisture of the compressed air supplied from the air compressor unit; A primary moisture remover comprising a reactor filled with a B type silica gel packed bed for removing moisture of compressed air supplied from the drain separator, and a band heater disposed around the reactor to remove moisture absorbed in the silica gel; The filter portion for removing dust and impurities from the compressed air supplied from the primary moisture removing agent and the oxygen having a high diffusion speed from the compressed air flowing through the filter portion are removed through the oxygen outlet, A high purity nitrogen production section including a membrane module section supplied through a supply port; A regulator for regulating a supply pressure of the nitrogen gas supplied from the high purity nitrogen producing unit; And a reactor filled with an A type silica gel packed bed for removing moisture and particles in a pressure-controlled nitrogen gas in the regulator.
Also, the primary moisture removing unit may include a SUS material reactor filled with a B type silica gel packed bed; A water outlet for discharging water in the reactor; A band heater disposed around the reactor of the SUS material to remove moisture absorbed in the silica gel; And a heat insulating material disposed around the band heater.
In addition, the filter unit may include a 1 mu m dust separation filter for separating dust from the compressed air supplied from the primary moisture removal unit, and a 0.1 mu m droplet separation filter for separating the droplet (Mist).
Also, the membrane module part may have a plurality of membranes connected in series.
The second water removal and particle removing unit may include a first PP reactor filled with an A type silica gel packed bed; And a second reactor of PP which is connected in series to the first reactor and is filled with an A type silica gel packed bed.
The high-purity nitrogen purifier may be provided inside the lower portion of the glove box body.
According to the highly functional glove box high purity nitrogen generating device according to the present invention, since the nitrogen generating device supplied to the glove box is integrally mounted in the glove box, it is not necessary to purchase it separately from the special gas supplier, By installing it on the inside of the body, it is possible to efficiently utilize the space of the laboratory and the laboratory.
In addition, B type silica gel is used to primarily remove moisture from compressed air, and A type silica gel can be used to secondarily remove moisture and particles in nitrogen gas, thereby providing higher purity nitrogen.
In addition, a band heater for removing the moisture absorbed in the silica gel is installed around the reactor filled with the B type silica gel packed bed, so that the B type silica gel absorbs moisture and removes the absorbed moisture by applying heat, The silica gel can be reused, and a double effect of water removal and cost reduction can be expected.
In addition, in the last stage, two reactors filled with the A type silica gel packed bed are connected in series to effectively remove water and particles in the nitrogen gas.
As a result, it is possible to supply high purity nitrogen with a purity of 99% or more, which can be supplied by itself in the glove box, and the content of water also contributes greatly to the inert conditions in the glove box by producing nitrogen containing water having a relative humidity of 1% It is effective.
