Fully automatic argon gas recovery and circulation equipment

The system of this device starts from the outlet valve behind the high-temperature furnace (the opening point of the oil-free vacuum pump is controlled by the high-temperature furnace):

A. The recovery gas starts from the dry vacuum pump and is then connected to a dual pulse filter. Under the monitoring of an oxygen analyzer, choose to empty or start the recovery gas collection.

B. Boosting system operation: The exhaust gas from the vacuum pump is monitored by an oxygen analyzer and selected for operation. The recovery program is initiated, and the pneumatic valve is opened to enter the buffer tank in front of the compressor. Under the action of the pressure sensor, the system operates automatically to complete pipeline purging and operate within the set data range. After primary dust filtration, precision secondary filtration, cooling, drying and dehydration, deoxygenation agent deoxygenation, drying and purification equipment deeply adsorbs and removes trace amounts of oxygen, water and gas impurities from the argon gas, obtaining argon gas with extremely high relative purity. Finally, it is sent to the working point for use through a precious metal precision filter.

The oxygen content in the recovered gas is less than 200ppm, containing trace amounts of carbon monoxide and hydrocarbons, or organic compounds produced at high temperatures, and containing particles below 3um,

Recycling requirements: After recycling, purification equipment is used to remove impurities such as oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and organic gases from argon gas. A dual pulse filter is used to filter particles and collect them.

Composition of recycling device:

1. Control from the source: Install a dual pulse filter after the vacuum pump to filter and collect particulate matter, so that the residual particulate matter in the gas entering the recovery system is less than 0.1um, reducing or eliminating the risk of blockage during system operation.

2. Install a trace oxygen analyzer at the source of recycling to monitor the oxygen content in the recycled gas source. Operate according to a self written program (with an optional oxygen content of 0-1000ppm), and release or recycle (with an audible and visual alarm when the release valve is opened).

3. Recycling and purification equipment: Adopting a multi-stage purification method, segmented processing, and layer by layer separation to maximize the demand for high-purity gas.

4. The recycling system and purification equipment are provided in a modular cabinet style, integrated and controlled by an automatic control system. The entire system is integrated into a mobile cabinet, and the power switch of the vacuum pump is controlled by the high-temperature furnace. The overall equipment has interlocking function to prevent misoperation. The data output terminal has a 485 interface, which can complete remote data transmission and control online. The supplier shall provide a main control panel that can be embedded into the main control console to complete the control of the entire equipment.

6. The overall recycling equipment is provided in a closed cabinet, with a computer gray painted appearance, a mobile caster design (with fixed pressure support pillars), a computer gray painted appearance, an independent control surface, and a beautiful and coordinated appearance. The overall floor area is about 2m (width) x2 (depth) x2m (height) (specific dimensions are subject to the actual product)
