Description

HIGH PURITY NITROGEN GENERATOR FOR HIGH FUNCTIONAL GLOVE BOX

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.

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.

Both ends of the reactor 32 made of SUS are made of flanges 36 and 37 made of SUS so that they can withstand the entire heat of the band heater 34 as a whole and are filled with B type silica gel in the reactor 32 made of SUS. The layer 31 absorbs the moisture sufficiently and then the heat absorbed by the band heater 34 outside the reactor 32 is absorbed and removed through the water outlet 33 so that the B type silica gel can be reused. It is a great advantage that B type silica gel can be reused while moisture removal can be smoothly performed.

B type silica gel has a large number of holes with small holes on its surface. It has a characteristic of absorbing a large amount of moisture and exhibits strong dehumidifying power at a relatively high humidity. Therefore, it is primarily suitable for removing moisture in the air and is recyclable.

The high-purity nitrogen producing unit includes a filter unit 40 for removing dust and impurities from the compressed air supplied from the primary water removing unit 30, and oxygen having a high diffusion rate from the compressed air flowing through the filter unit 40, And a membrane module unit 50 for removing nitrogen through the nitrogen outlet and nitrogen gas having a low diffusion rate through a nitrogen supply port.

The membrane module unit 50 may include a plurality of membranes connected in series, and preferably a gas separator membrane connected in series in four stages. As a result of the four-step series connection, the gas having a high diffusion rate such as oxygen is sufficiently discharged to the outside, and finally, only nitrogen can be supplied.

A regulator (60) regulates the supply pressure of the nitrogen gas supplied from the high purity nitrogen production section.

The flow meter 70 measures the amount of pressure-regulated nitrogen gas flowing in the unit time in the regulator 60. The operator can adjust the pressure of the regulator and measure the amount of nitrogen gas flowing per unit time through the flow meter.

The secondary moisture removal and particle removing unit 80 includes a reactor filled with an A type silica gel filling layer that removes moisture and particles in the nitrogen gas through the flow meter 70 after the pressure is regulated in the regulator 60.

Specifically, the secondary moisture removal and particle removing unit 80 is connected in series to a first reactor 82 and a first reactor 82 of PP, which are filled with an A-type silica gel filling layer 81 And a second reactor 86 of PP filled with a silica gel filling layer 85 of A type. The first reactor 82 and the second reactor 86 are constructed in a two-stage tandem arrangement connected to a pipe 89 made of PP. The flanges 83 and 84 at both ends of the first reactor 82, The flanges 87 and 88 at both ends of the frame 86 are made of a PP material.
