At described counterbalance valve C23, by valve B24, pressure-reducing valve B40, be connected with the flowmeter 25 of testing product gas.
Embodiment bis-
As shown in Figure 2, the present embodiment is applied to high-purity, the high compacting gas equipment based on PSA technology, is with the difference of embodiment mono-:
One, between described pressure swing adsorption gas separation device 12 and counterbalance valve B18, be parallel with displacement gas bypass 16, in described displacement gas bypass 16, be provided with check valve B17 and choke valve 19.Counterbalance valve B18 place before gas product surge tank 20, displacement gas bypass 16 in parallel is set, by the throttle orifice of the check valve B17 in displacement gas bypass and choke valve 19, by the qualified products gas being stored in gas product surge tank 20, after pressure-swing absorber A13 or pressure-swing absorber B14 all press, again pressure-variable adsorption top of tower is pressed forward with the gas of impurity, all pressing under the condition of (lower than operating pressure) simultaneously, displace the impurity of pressure-variable adsorption top of tower absorption, reduce the gaseous impurity concentration containing in adsorbent, make pressure-variable adsorption top of tower in strong adsorbed state, the purity of product gas of further guaranteeing pressure swing adsorption gas separation device output is higher.
Two,, on the pipeline between counterbalance valve C23 and valve D27, be set to the blow-off pipe of waste liquid separated and collected device 38, and valve L45 is set on pipeline.Its object and embodiment mono-are similar, can in the situation that stage of starting working of equipment or may occur in the course of the work exporting substandard product gas the substandard product gas of output is discharged in time, thereby shorten system time; Can play blowdown effect in addition.
Embodiment tri-
As shown in Figure 3, in the present embodiment, between valve H34 and middle high-pressure gas cylinder 35 between check valve B17 and gas product surge tank 20, decompression being set and recharging pipeline 46, reducing pressure to recharge arranges valve I36, pressure-reducing valve A37 on pipeline 46; The high purity product gas that device separates goes out, is stored in middle high-pressure gas cylinder 35; When needs are when producing highly purified gas product once starting shooting, by the high pressure high purity product gas being stored in middle high-pressure gas cylinder 35, through pressure-reducing valve A37 reduced pressure delivery in gas product surge tank 20, under duty and condition of work when realizing pressure swing adsorption gas separation device being just in normal separation, output high purity product gas when a start, thereby further shortened system time, reduced operating cost.
The blow-off pipe of gas product surge tank 20 and valve L45, is pooled to the secondary air inlet of source of the gas compressor 1, forms gas recovery pipe road 43, and check valve D44 is set on gas recovery pipe road 43, prevents gas backstreaming, realizes the recycling of defective gas (waste gas).
After application the technical solution of the utility model, high-purity, high compacting gas equipment based on PSA technology is in normal work, as long as there is the low pressure unstripped gas that reaches equipment job requirement, equipment just can produce qualified gas product, equipment is without system time, even do not arrange and automatically unloads place system because of the indispensable substandard product gas of the long-time discharge of need; In the debug process of only not dispatching from the factory at equipment, and equipment is after maintenance, the system flow space of equipment has in the situation of unstripped gas or impure gas product, the gas product of manufacturing in the time of just need to starting shooting, the unstripped gas in device systems space or impure gas product are replaced, due to high for the purity of product gas of replacing, need the time of displacement short, therefore system time is also very short.
In technique scheme, by controlling the pressure in technological process, can produce the high purity product gas of middle high-pressure, guarantee meeting under the pressure condition of purity requirement simultaneously, the flow of equipment output high purity product gas is always in optimum state.The flow of having avoided existing equipment to export by continuous adjustment equipment, control the quality (purity) of gas product, or the purity situation of looking gas product, by continuous adjusting unstripped gas gas source and flow amount, control the output flow of gas product, and cause the pressure in existing equipment to occur wide fluctuations, make existing equipment be in for a long time unsure state.Also the purity of product gas of having avoided existing equipment output is when requiring, because because regulating difficulty, (gas product surge tank 20 volumes are larger, the gas product of exporting with the delivery outlet of pressure swing adsorption gas separation device 12 has larger hysteresis quality, in addition the detection hysteresis quality of purity of product gas analyzer 22, the purity that can not effectively regulate in good time, detect output products gas, the adjusting time is long.), and no longer carry out the adjusting of purity of product gas, and make the purity of product gas of output, be in for a long time the state higher than index request, thereby bring unnecessary energy waste.
When equipment is in hypobaric, or source of the gas pipeline has leakage phenomenon, or the source of the gas compressor performance variation of equipment, and capacity reduces, as long as reach the minimum pressure that equipment can normally be worked, equipment output must be just qualified gas product.If the operating pressure that the equipment that do not reach is minimum, output products gas, does not have the system of underproof gas product contaminated equipment and user's gas pipeline network, equipment of the present utility model, and environmental suitability is very strong.
In technique scheme, the gas product that pressure swing adsorption gas separation device 12 is manufactured, not step-down in the process that is transported to gas product supercharger 28, gas product is not in the situation that being depressurized, more be conducive to carry, in the situation that particularly gas product needs to use after supercharging storage or supercharging, avoided the very large energy waste causing because of repressurize after reducing pressure.
