Description of drawings
Fig. 1 is the theory diagram of high-purity mist compounding system.
The specific embodiment
As shown in Figure 1, this high-purity mist compounding system comprises respectively the gas mixed cell that is connected with metering units with first air supply unit, second air supply unit, analytic unit;
Described first air supply unit comprises gas collection dress lattice, decompressor and the filter that connects successively; Described second air supply unit comprises cryogenic liquid tank, vaporizer, decompressor and the filter that connects successively; Filter in described first air supply unit all is connected with the gas mixed cell with filter in second air supply unit.
Described gas mixed cell comprises blender and the surge tank that links together; Described blender is connected with filter, and surge tank is connected with metering units with analytic unit respectively; Also be connected with compensating unit on the pipeline between described surge tank and the metering units; Described compensating unit comprises gaseous mixture collection dress lattice and decompressor, and described gaseous mixture collection dress lattice are connected on the pipeline between surge tank and the metering units by decompressor, and compensating unit replenishes pipe network automatically by the identification of pressure signal; Described first air supply unit and/or the second air supply unit inside also are provided with the fuel gas protective device; Described fuel gas protective device comprises smoke alarm and the temperature controller that is installed in first air supply unit and/or the second air supply unit region.
Below with nitrogen account for 95%, to account for 5% mist be example to hydrogen, this system is described in detail:
At first, high-purity liquid nitrogen (99.999 ~ 99.9995%) is delivered to vaporizer by cryogenic liquid tank, through become the high pure nitrogen of 1.1 ~ 1.4Mpa pressure gaseous state after the heat exchange by liquid nitrogen, and deliver to decompressor by pipeline, drop to 0.95Mpa through post-decompression nitrogen pressure, be sent to filter again, then enter blender; The hydrogen of gas collection dress lattice is transported to the special-purpose decompressor that is used for hydrogen through piping, and this device can also switch the assurance device outlet pressure automatically according to pressure at two ends except the purpose that realizes decompression.Decompressor is decompressed to hydrogen and is transported to behind the 1.0Mpa after filter becomes clean hydrogen by 13Mpa, send into blender again.
Two kinds of gases are sent into surge tank by pipeline after preparing and finishing in blender; With the tank connected analytic unit of buffering, can analyze the gas that blender configures incessantly, when the hydrogen ratio met production requirement in the sample gas, system continued normal preparation.Find that when analytic unit the hydrogen ratio is too high or too low in the sample gas, stop blender work immediately, to guarantee the quality of gas.
When power failure, system broke down shutdown or gas transmission pipeline net work hypotony, in order to guarantee client's ordinary production, the pressure-regulating valve of compensating unit can in time be opened, to the gas transmission pipeline net work air feed.
When hazardous gas being mixed system, because fuel gas is easy to take place burning or blast, in order to solve this hidden danger, smoke alarm and the temperature controller installed in first air supply unit and/or the second air supply unit region can be monitored the safe condition in production place in real time.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement to the utility model, these improvement also fall in the protection domain of the utility model claim.
