Description

IZGUDROJUMA APRAKSTSDESCRIPTION OF THE INVENTION

[001] Izgudrojums attiecas uz mašīnbūves jomu, jo īpaši uz hidrauliskās kompresijas ierīcēm, proti kompresoriem, kuros šķidra un gāzveida vide vienlaicīgi tiek ievadīta darba kamerā, un to var izmantot ūdeņraža hidrauliskajai kompresijai.[001] The invention relates to the field of mechanical engineering, in particular to hydraulic compression devices, namely compressors in which liquid and gaseous media are simultaneously introduced into the working chamber, and can be used for hydraulic compression of hydrogen.

Zināmais tehnikas līmenisThe known state of the art

[002] Gāzes hidrauliskās kompresijas tehnoloģijai ir vairākas būtiskas priekšrocības salīdzinājumā ar virzuļkompresoriem. Zināmajā tehniskajā risinājumā [1] ir īstenota kompresora konstrukcija, kurā virzulis saspiež darba šķidrumu cilindrā ar noteiktu tilpumu un ievada to citā tvertnē, kas caur ieplūdes vārstu ir piepildīta ar gāzi. Kad tvertne tiek piepildīta ar darba šķidrumu, tiek saspiesta gāze, kas cikla beigās caur atvērto izplūdes vārstu tiek izspiesta uzglabāšanas tvertnē. Katra cikla beigās spiediens uzglabāšanas tvertnē diskrēti palielinās un sasniedz gāzes spiediena līmeni cilindrā.[002] Gas hydraulic compression technology has several significant advantages over reciprocating compressors. The known technical solution [1] implements a compressor design in which a piston compresses the working fluid in a cylinder with a certain volume and introduces it into another tank, which is filled with gas through the inlet valve. When the tank is filled with the working fluid, the gas is compressed, which at the end of the cycle is forced out through the open outlet valve into the storage tank. At the end of each cycle, the pressure in the storage tank increases discretely and reaches the gas pressure level in the cylinder.

[003] Zināmās konstrukcijas trūkums ir tāds, ka kompresijas kameras tilpums nevar pārsniegt virzuļsūkņa cilindra tilpumu. Tas ierobežo iespēju saspiest lielu gāzes daudzumu vienā ciklā un attiecīgi samazina sūkņa efektivitāti.[003] A disadvantage of the known design is that the volume of the compression chamber cannot exceed the volume of the piston pump cylinder. This limits the possibility of compressing a large amount of gas in one cycle and accordingly reduces the efficiency of the pump.

[004] Lai kontrolētu kompresijas pakāpi zināmajos tehniskajos risinājumos [2, 3], gāzes kompresijas tvertnes iekšpusē tiek ierosināts ievietot plāksni, kas peld uz darba šķidruma virsmas. Pie maksimālā uzpildes līmeņa plāksne paceļas un iedarbojas uz sensoru, kas izslēdz darba šķidruma padevi tvertnē.[004] In order to control the degree of compression in the known technical solutions [2, 3], it is proposed to insert a plate floating on the surface of the working fluid inside the gas compression tank. At the maximum filling level, the plate rises and acts on the sensor, which turns off the supply of working fluid to the tank.

Izgudrojuma mērķis un būtībaPurpose and essence of the invention

[005] Šī metode, kā kontrolēt tvertnes tilpuma piepildīšanu ar darba šķidrumu, ir saistīta ar plāksnes stāvokļa nenoteiktību šķidruma kustīgajā tilpumā, kas samazina darba šķidruma līmeņa noteikšanas precizitāti tvertnē. Tā rezultātā ierīcei ir ierobežojumi gāzes kompresijas pakāpē, un samazinās ierīces drošums. Ierīces darbības laikā ūdeņraža kompresijas pakāpe netiek regulēta.[005] This method of controlling the filling of the tank volume with the working fluid is associated with the uncertainty of the position of the plate in the moving volume of the fluid, which reduces the accuracy of determining the level of the working fluid in the tank. As a result, the device has limitations in the degree of gas compression, and the safety of the device decreases. During the operation of the device, the degree of hydrogen compression is not regulated.

[006] Šī izgudrojuma tehniskais uzdevums ir nodrošināt iespēju kontrolēt ūdeņraža kompresijas līmeni, palielināt ūdeņraža hidrauliskās kompresijas ierīces produktivitāti un drošumu.[006] The technical task of this invention is to provide the ability to control the level of hydrogen compression, to increase the productivity and safety of the hydrogen hydraulic compression device.

During this period, the valve (52) opens, through which the tank (27) is filled with atmospheric pressure air.

[0018] Informācija no šķidruma plūsmas sensora (29) nonāk kontrolierī (1), kur to salīdzina ar iepriekš noteikto šķidruma tilpuma robežlīmeni, kas jāiesūknē otrajā darba cilindrā (3). Piepildot cilindra (3) darbtelpu ar darba šķidrumu (24), samazinās ūdeņraža aizņemtais tilpums un palielinās spiediens šajā cilindrā.[0018] The information from the liquid flow sensor (29) goes to the controller (1), where it is compared with the predetermined limit level of the liquid volume to be pumped into the second working cylinder (3). When filling the working space of the cylinder (3) with the working fluid (24), the volume occupied by hydrogen decreases and the pressure in this cylinder increases.

[0019] Šķidruma plūsmas sensora (29) izmantošana ļauj vienkāršot tvertnes piepildīšanas ar darba šķidrumu (24) uzraudzību. Tajā pašā laikā saskaņā ar Boila-Mariota formulu tiek aprēķināts ūdeņraža spiediens slēgtajā otrajā darba cilindrā (3), kas palielināsies proporcionāli tā aizņemtā tilpuma samazinājumam.[0019] The use of a liquid flow sensor (29) makes it possible to simplify the monitoring of the filling of the tank with the working liquid (24). At the same time, according to the Boyle-Mariot formula, the hydrogen pressure in the closed second working cylinder (3) is calculated, which will increase in proportion to the decrease in its occupied volume.

[0020] Nākamā vārstu (15) un (52) aizvēršanas komanda nāk no kontroliera (1), pamatojoties uz sensoru (29) informāciju par darba cilindrā (3) iesūknētā darba šķidruma (24) daudzumu. Kad tiek sasniegts otrā darba cilindra (3) iepriekš iestatītais piepildījuma līmenis, atveras vārsts (14). Tajā pašā laikā atveras vārsts (23), caur kuru saspiestais ūdeņradis nonāk augstspiediena cauruļvadā (25) un tiek piegādāts buferšķīduma tvertnē (26).[0020] The next command to close the valves (15) and (52) comes from the controller (1) based on information from sensors (29) about the amount of working fluid (24) pumped into the working cylinder (3). When the preset filling level of the second working cylinder (3) is reached, the valve (14) opens. At the same time, the valve (23) opens, through which the compressed hydrogen enters the high-pressure pipeline (25) and is supplied to the buffer tank (26).

[0021] Buferšķīduma tvertnes (26) izmantošana ļauj vienlaicīgi veikt saspiesta ūdeņraža aizvadīšanas darbību no viena cilindra (2 vai 3) un sūknēt darba šķidrumu otrā darba cilindrā (3 vai 2). Tā rezultātā tiek nodrošināti apstākļi, kuros ūdeņraža pirmā kompresijas posma šķidruma sūknis (13) turpina darboties ar nemainīgu slodzi, netērējot laiku darba šķidruma (24) plūsmas pārslēgšanai no viena darba cilindra uz otru.[0021] The use of the buffer solution tank (26) allows simultaneous operation of removing compressed hydrogen from one cylinder (2 or 3) and pumping the working liquid into the other working cylinder (3 or 2). As a result, conditions are provided in which the fluid pump (13) of the first stage of hydrogen compression continues to operate at a constant load, without wasting time switching the flow of the working fluid (24) from one working cylinder to another.

[0022] Vārsts (23) aizveras pēc aprēķināta laika, kura laikā spiediens otrajā darba cilindrā (3) un buferšķīduma tvertnē (26) izlīdzinās. Tajā pašā laikā pirmais darba cilindrs (2) tiek piepildīts ar darba šķidrumu (24), un tajā notiek ūdeņraža kompresijas process, kas aprakstīts otrajam darba cilindram (3).[0022] The valve (23) closes after a calculated time during which the pressure in the second working cylinder (3) and the buffer solution tank (26) equalize. At the same time, the first working cylinder (2) is filled with working fluid (24) and undergoes the hydrogen compression process described for the second working cylinder (3).

[0023] Pabeidzot saspiestā ūdeņraža sūknēšanu no otrā darba cilindra (3) uz buferšķīduma tvertni (26), tiek atvērti vārsti (7 un 21). Ūdeņraža padeves blokā (9) esošā spiediena ietekmē darba šķidrums (24) plūst caur cauruli (19) un šķidruma plūsmas sensoru (30) tvertnē (27). Informācija no sensora (30) izejas nonāk kontrolierī (1), kas dod komandu aizvērt vārstus (7) un (21).[0023] Upon completion of the pumping of compressed hydrogen from the second working cylinder (3) to the buffer tank (26), the valves (7 and 21) are opened. Under the influence of the pressure in the hydrogen supply unit (9), the working fluid (24) flows through the pipe (19) and the fluid flow sensor (30) into the tank (27). Information from the output of the sensor (30) goes to the controller (1), which gives the command to close the valves (7) and (21).

[0024] Kad tiek sasniegts pirmā darba cilindra (2) iepriekš iestatītais tvertnes piepildījuma līmenis, vārsts (14) tiek aizvērts un vārsts (15) tiek atvērts. Tajā pašā laikā atveras vārsts (22), caur kuru saspiestais ūdeņradis nonāk augstspiediena cauruļvadā (25) un tiek piegādāts buferšķīduma tvertnē (26). Vārsts (22) aizveras pēc aprēķināta laika, kura laikā spiediens pirmajā darba cilindrā (2) un buferšķīduma tvertne (26) izlīdzinās. Tajā pašā laikā otrais darba cilindrs (3) tiek piepildīts ar darba šķidrumu (24), un tajā notiek ūdeņraža kompresijas process. [0025] Katra cikla beigās ūdeņraža spiediens buferšķīduma tvertnē (26) palielinās. Pēc noteikta ūdeņraža kompresijas ciklu skaita pēc kontroliera (1) komandas tiek atvērts regulējamais vārsts (35), un saspiestais ūdeņradis no buferšķīduma tvertnes (26) nonāk ūdeņraža otrās kompresijas stadijas augstspiediena uzglabāšanas tvertnē (37). Pēc tam regulējamais vārsts (35) tiek aizvērts, un atkārtojas ūdeņraža kompresijas un iesūknēšanas cikls buferšķīduma tvertnē (26), līdz saspiestā ūdeņraža spiediena līmenis buferšķīduma tvertnē (26) sasniedz saspiestā ūdeņraža spiediena līmeni attiecīgajā darba cilindrā (2 vai 3). [0026] Pēc ūdeņraža otrās kompresijas stadijas augstspiediena uzglabāšanas tvertnes (37) piepildīšanas ar ūdeņradi ar spiedienu, kas sasniegts ūdeņraža kompresijas pirmā stadijas darba cilindros (2; 3), regulējamais vārsts (35) tiek aizvērts. Atveras vārsts (53), caur kuru tvertne (48) ūdeņraža kompresijas otrās pakāpes darba šķidruma (24) uzglabāšanai tiek piepildīta ar atmosfēras spiediena gaisu, un tiek ieslēgts ūdeņraža otrās kompresija stadijas šķidruma sūknis (41).[0024] When the pre-set tank filling level of the first working cylinder (2) is reached, the valve (14) is closed and the valve (15) is opened. At the same time, the valve (22) opens, through which the compressed hydrogen enters the high-pressure pipeline (25) and is supplied to the buffer tank (26). The valve (22) closes after a calculated time during which the pressure in the first working cylinder (2) and the buffer tank (26) equalize. At the same time, the second working cylinder (3) is filled with the working fluid (24) and the hydrogen compression process takes place in it. [0025] At the end of each cycle, the hydrogen pressure in the buffer tank (26) increases. After a certain number of hydrogen compression cycles, at the command of the controller (1), the adjustable valve (35) is opened, and the compressed hydrogen from the buffer tank (26) enters the high-pressure storage tank (37) of the second hydrogen compression stage. The control valve (35) is then closed and the cycle of hydrogen compression and injection into the buffer tank (26) is repeated until the compressed hydrogen pressure level in the buffer tank (26) reaches the compressed hydrogen pressure level in the corresponding working cylinder (2 or 3). [0026] After filling the high-pressure storage tank (37) of the second stage of hydrogen compression with hydrogen at the pressure reached in the working cylinders (2; 3) of the first stage of hydrogen compression, the control valve (35) is closed. The valve (53) opens, through which the tank (48) for storing the working liquid (24) of the second stage of hydrogen compression is filled with atmospheric pressure air, and the pump (41) of the liquid of the second stage of hydrogen compression is turned on.

[0027] Caur atvērto vārstu (39) no tvertnes (48) ūdeņraža otrās kompresijas stadijas uzglabāšanas tvertnē (37) tiek piegādāts darba šķidrums (24), kas saspiež ūdeņradi līdz augstākam spiediena līmenim, kurš atbilst ūdeņraža otrajai kompresijas stadijai iepriekš noteiktajam spiediena līmenim. Ūdeņraža kompresijas process tvertnē (37) tiek kontrolēts, izmantojot šķidruma plūsmas sensora (50) izejas informāciju.[0027] Through the open valve (39), a working fluid (24) is supplied from the tank (48) to the storage tank (37) of the second hydrogen compression stage, which compresses the hydrogen to a higher pressure level, which corresponds to the predetermined pressure level of the second hydrogen compression stage. The process of hydrogen compression in the tank (37) is controlled using the output information of the liquid flow sensor (50).

[0028] Pēc ūdeņraža kompresijas cikla pabeigšanas otrajā stadijā pēc no kontroliera (1) saņemtās komandas izejas vārsts (39) tiek aizvērts, vārsts (45) atveras, un ūdeņradis, kas ir tiek saspiests līdz otrās kompresijas stadijas spiediena līmenim, caur otrā regulējama vārsta (45) izeju (51) nonāk līdz patērētājam.[0028] After the completion of the hydrogen compression cycle in the second stage, after the command received from the controller (1), the output valve (39) is closed, the valve (45) opens, and the hydrogen that is compressed to the pressure level of the second compression stage through the second adjustable valve (45) output (51) reaches the consumer.

[0029] Pēc tam vārsts (45) aizveras un vārsts (44) atveras. Šķidrums no tvertnes (37) caur atvērto vārstu (44) tiek novadīts tvertnē (48), lai uzglabātu darba šķidrumu (24). Tas notiek laikā, kad tvertne (37) caur regulējamo vārstu (35) ir piepildīta ar ūdeņradi no buferšķīduma tvertnes (26). Lai kontrolētu regulējamos vārstus (35; 44), tiek izmantota informācija no otro šķidruma plūsmas sensoru (49; 50) izejas.[0029] Then valve (45) closes and valve (44) opens. The fluid from the tank (37) is directed through the open valve (44) to the tank (48) to store the working fluid (24). This happens when the tank (37) is filled with hydrogen from the buffer tank (26) through the adjustable valve (35). Information from the output of the second liquid flow sensors (49; 50) is used to control the adjustable valves (35; 44).

[0030] Spiedienu tvertnēs (27; 48) darba šķidruma uzglabāšanai kontrolē spiediena sensori (54; 55), savukārt spiediens augstspiediena cauruļvadā (25) un izejas caurulē (42) ūdeņraža kompresijas pirmajā un otrajā stadijā tiek kontrolēts ar spiediena sensoriem (56 un 57).[0030] The pressure in the tanks (27; 48) for storing the working fluid is controlled by the pressure sensors (54; 55), while the pressure in the high-pressure pipeline (25) and the outlet pipe (42) in the first and second stages of hydrogen compression is controlled by the pressure sensors (56 and 57 ).

[0031] Cauruļu (18; 19; 43) atrašanās vieta darba cilindru (2; 3) un tvertnes (37) apakšējā daļā nodrošina darba šķidruma (24) aizplūšanu un paātrina tā aizvadīšanas procesu uz tvertnēm (27; 48).[0031] The location of the pipes (18; 19; 43) in the lower part of the working cylinders (2; 3) and tank (37) ensures the outflow of the working fluid (24) and accelerates the process of its removal to the tanks (27; 48).

[0032] Tvertnes (27; 48) darba šķidruma (24) uzglabāšanai var savstarpēji savienot. Šajā gadījumā regulējamo vārstu (53) un spiediena sensoru (55) funkciju veiks regulējamais vārsts (52) un spiediena sensors (54).[0032] The tanks (27; 48) for storing the working fluid (24) can be interconnected. In this case, the function of adjustable valves (53) and pressure sensors (55) will be performed by adjustable valve (52) and pressure sensor (54).

[0033] Šķidruma plūsmas sensoru izmantošana ūdeņraža kompresijas procesa kontrolē ļauj kontrolēt ūdeņraža kompresijas pakāpi, pielāgojot darba šķidruma padeves tilpumu darba cilindros (2; 3). Tādējādi šī izgudrojuma ūdeņraža hidrauliskās kompresijas ierīcē, izmantojot šķidruma plūsmas sensorus un buferšķīduma tvertni saspiestā ūdeņraža uzkrāšanai, tiek panākts produktivitātes pieaugums, samazinot katra ūdeņraža kompresijas cikla laiku.[0033] The use of liquid flow sensors in the control of the hydrogen compression process allows controlling the degree of hydrogen compression by adjusting the supply volume of the working fluid in the working cylinders (2; 3). Thus, in the hydrogen hydraulic compression device of the present invention, by using liquid flow sensors and a buffer tank to store the compressed hydrogen, an increase in productivity is achieved by reducing the time of each hydrogen compression cycle.

[0034] Turklāt ūdeņraža hidrauliskās kompresijas ierīce palielina drošumu, jo korpusa sienās nav papildu caurumu un samazinās mērīšanas sensoru skaits.[0034] In addition, the hydrogen hydraulic compression device increases safety, as there are no additional holes in the housing walls and the number of measurement sensors is reduced.
