Description
Technical field
The utility model relates to a kind of gas drier, especially relates to a kind of for dried compressed air and the dryer of not loss compressed air require.
Background technology
Compressed air needs first to carry out drying process, to remove the steam in compressed air before use.Dryer is the common equipment for dried compressed air, it generally includes two adsorption towers, arranges the granular adsorbent with adsorption function in adsorption tower, when compressed air is by adsorption tower, steam in the adsorbable compressed air of adsorbent, thus export dry compressed air.When the steam that the adsorbent in adsorption tower adsorbs reaches capacity, then can input hot-air in adsorption tower, the water evaporation that adsorbent is adsorbed is to realize thermal regeneration, and then in adsorption tower, input cold air adsorbent cold blowing is regenerated, thus recovery adsorption function, two adsorption towers can switch back and forth between absorption and regeneration two states, thus realize compressed-air actuated continuous drying.When an adsorption tower is operated in adsorbed state, after compressed air is partly heated by heater, thermal regeneration is carried out to another adsorption tower, and then after being cooled by cooler by the compressed air of part, cold blowing regeneration is carried out to the adsorption tower after thermal regeneration.Because the regeneration source of the gas of adsorption tower is from compressed air, therefore dryer operationally can consume a certain amount of compressed air, thus reduces the operating efficiency of dryer.For this reason, people have invented the dryer of zero gas consumption, such as, in Chinese patent literature disclosed a kind of " compression waste heat zero regeneration gas loss absorption drier ", notification number is CN203803342U, by dryer entrance, A adsorption tower, B adsorption tower, dryer outlet, the first after cooler, gas-liquid separator, the second after cooler, diffuser form.Dryer entrance is arranged on the side of B adsorption tower, dryer outlet is adsorbed to train with A respectively by flanged pipe and is communicated with B adsorption tower, diffuser is separately positioned on the top and the bottom of A adsorption tower and B adsorption tower, second after cooler is arranged between A adsorption tower and B adsorption tower, and be communicated with flanged pipe, the first after cooler connects gas-liquid separator by flanged pipe.During work, compressed air, successively by A, B two adsorption towers, makes two adsorption towers be operated in absorption and reproduced state respectively, thus can avoid consumption of compressed air amount, compressed-air actuated flow is remained unchanged.But still there are the following problems for it: because whole compressed air participates in the regeneration of adsorption tower simultaneously, that is, compressed air is just sent after having to pass through two adsorption towers, therefore the resistance suffered by compressed air increases greatly, thus the compressor load of upstream is significantly increased, and then increase the power of compressor and cause waste.
Utility model content
It is large thus need correspondingly to improve the power of compressor and wasting problem that the purpose of this utility model is to solve compressed air resistance existing for existing zero gas consumption dryer, a kind of zero gas consumption blowing-type dryer is provided, it can not increase compressed-air actuated resistance under the prerequisite of maintenance zero gas consumption, thus really realize zero gas consumption of dryer, effectively to reduce energy consumption.
To achieve these goals, the utility model is by the following technical solutions:
A kind of zero gas consumption blowing-type dryer, comprise the air inlet pipe of input compressed-air, export dried compressed-air actuated escape pipe, and for the first adsorption tower of dried compressed air successively, second adsorption tower, described air inlet pipe is respectively by pipeline and first, the air inlet of the second adsorption tower is in parallel, and the motor-driven valve that automatically can control break-make is set respectively on two parallel pipelines, described escape pipe is respectively by pipeline and first, the gas outlet of the second adsorption tower is in parallel, and arrange respectively by first on two parallel pipelines, the gas outlet of the second adsorption tower is to the check-valves of escape pipe one-way conduction, in addition, also comprise air blast, be in parallel with the gas outlet of first, second adsorption tower after the air outlet of air blast is connected in series cooler and heater successively by pipeline, and arrange by the check-valves of air blast to the gas outlet one-way conduction of first, second adsorption tower on two parallel pipelines respectively, the air inlet of air blast is in parallel by the air inlet of pipeline and first, second adsorption tower, and on two parallel pipelines, arrange the motor-driven valve that automatically can control break-make respectively.
Dryer of the present utility model has absorption and regeneration two separate gas circuits, therefore, compressed air only can directly need export from escape pipe through an absorption tower adsorbs drying in dryer, the thermal regeneration of another adsorption tower and the air-flow required for cold blowing regeneration are then produced by the air blast in regeneration gas circuit, like this, both zero gas consumption of dryer can really have been realized, make dryer be reduced to minimum level to compressed-air actuated resistance simultaneously, thus be conducive to the power and the energy consumption that reduce upstream compressor.When the first adsorption tower is operated in adsorbed state, the opening and closing of two motor-driven valves on the pipeline that the air inlet that we only need control to be arranged on air inlet pipe and first, second adsorption tower is in parallel, can control the air inlet that Compressed Gas enters the first adsorption tower and complete adsorption dry.Owing to being provided with the check-valves of one-way conduction between the gas outlet of first, second adsorption tower and escape pipe, therefore, mutually isolated effect is formed between the gas outlet of first, second adsorption tower, the compressed air completing adsorption dry all exports from escape pipe by the check-valves be connected between the gas outlet of the first adsorption tower and escape pipe, thus forming an absorption gas circuit, the Compressed Gas flowed out from the gas outlet of the first adsorption tower oppositely can't enter in the second adsorption tower from the gas outlet of the second adsorption tower.In addition, we are by the air inlet and first of opening and closing air blast, motor-driven valve on parallel pipeline between the air inlet of the second adsorption tower, the air inlet of the second adsorption tower can be made to be connected with the air inlet of air blast, like this, air blast can drive the gas in pipeline first to cool through heater heating or cooler, to form the hot-air needed for thermal regeneration or the cold air needed for cold blowing regeneration, and enter in the second adsorption tower by the check-valves after heater and between the gas outlet of the second adsorption tower from the gas outlet of the second adsorption tower, independently gas circuit is regenerated to form one, thus make the second adsorption tower be operated in thermal regeneration or cold blowing reproduced state.Because the gas pressure of the now gas outlet of the first adsorption tower will far above the gas pressure of regeneration gas circuit, therefore, the hot-air formed through heater heating or cooler cooling or cold air can not enter into the absorption gas circuit of the side, gas outlet of the first adsorption tower, thus it is completely isolated to realize adsorbing between gas circuit and regeneration gas circuit.By optionally controlling the opening and closing of the motor-driven valve of being correlated with, we can switch the duty of first, second adsorption tower easily, thus the continuous drying realizing dryer runs.
As preferably, be connected by pipeline between the gas outlet of first, second adsorption tower described, and on this connecting line, be serially connected with manual adjustments flow valve and the motor-driven valve that automatically can control break-make.
Due to adsorption tower be operated in adsorbed state time, gas pressure in its tower is higher, and adsorption tower is when being operated in reproduced state, gas pressure in its tower is lower, therefore, when first, second adsorption tower switch operating state, we first can open the motor-driven valve between the gas outlet of first, second adsorption tower, the gas pressure be originally in the adsorption tower of adsorbed state is made to be lowered into reproduced state rapidly, manual adjustments flow valve then can control the gas flow of this connecting line, thus controls the switch speed of adsorption tower duty.
As preferably, be also connected with motor-driven valve and suction filter in turn by pipeline in the air inlet of air blast.
Like this, when one of them adsorption tower is switched to reproduced state, the gas in its regeneration gas circuit can suck from outside atmosphere, and forms clean regeneration gas after being filtered by suction filter, thus forms open regeneration gas circuit.When closing the motor-driven valve after being connected to suction filter, suction filter quits work, and regeneration gas circuit now forms closed gas circuit, the gas circulating flow in regeneration gas circuit, carries out thermal regeneration or cold blowing regeneration to one of them adsorption tower.
As preferably, the adsorbent in first, second adsorption tower described adopts alumina particle.
Aluminium oxide has good adsorption, and be conducive to the drying efficiency improving dryer, simultaneous oxidation aluminium has higher hardness, not fragile, is conducive to increasing the service life.
Therefore, the utility model has following beneficial effect: can not increase compressed-air actuated resistance under the prerequisite of maintenance zero gas consumption, thus really realizes zero gas consumption of dryer, and effectively reduces energy consumption.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further described.
As shown in Figure 1, a kind of zero gas consumption blowing-type dryer, comprise the air inlet pipe 3 of input compressed-air, export dried compressed-air actuated escape pipe 4 and the first adsorption tower 1, second adsorption tower 2 for dried compressed air successively, adsorbent in first, second adsorption tower adopts the alumina particle with good adsorption usefulness, to be conducive to the drying efficiency improving dryer, increase the service life simultaneously.At the first adsorption tower, in second adsorption tower, when an adsorption tower is operated in adsorbed state, another adsorption tower is then operated in reproduced state, air inlet pipe is respectively by pipeline and first, the air inlet of the second adsorption tower is formed and is connected in parallel, and the motor-driven valve that automatically can control break-make is set respectively on two parallel pipelines, motor-driven valve between the air inlet being wherein connected to air inlet pipe and the first adsorption tower is the 3rd motor-driven valve 53, motor-driven valve between the air inlet being connected to air inlet pipe and the second adsorption tower is the 4th motor-driven valve 54, by controlling the opening and closing of two motor-driven valves, namely optionally the compressed air of air inlet pipe is sent in the first or second adsorption tower, two adsorption towers are made to realize the continuous operation of dryer by mutual switch operating state.In addition, the escape pipe of output squeezing air is respectively by pipeline and first, the gas outlet of the second adsorption tower is formed and is connected in parallel, and arrange respectively on two parallel pipelines can the check-valves of one-way conduction, check-valves between the gas outlet being wherein connected to escape pipe and the first adsorption tower is the first check-valves 61, check-valves between the gas outlet being connected to escape pipe and the second adsorption tower is the second check-valves 62, the conducting direction of two check-valves is respectively from first, the side, gas outlet of the second adsorption tower is towards escape pipe side, that is, from first, the compressed air that the gas outlet of the second adsorption tower exports enters escape pipe by check-valves, compressed air in escape pipe then cannot flow back to first, second adsorption tower.
In order to realize zero gas consumption of dryer, the utility model also comprises an air blast 7, the air outlet of air blast is connected in series after cooler 8 and heater 9 again with first successively by pipeline, the gas outlet of the second adsorption tower is formed and is connected in parallel, and connect first at two, the parallel pipeline of the second adsorption tower gas outlet arranges check-valves respectively, the check-valves be wherein arranged on the parallel pipeline of connection first adsorption tower gas outlet is the 3rd check-valves 63, the check-valves be arranged on the parallel pipeline of connection second adsorption tower gas outlet is the 4th check-valves 64, 3rd, the conducting direction of the 4th check-valves respectively from the air outlet side of air blast towards first, the side, gas outlet of the second adsorption tower, that is, export from the air outlet of air blast and enter the first adsorption tower through the regeneration gas of subcooler cooling or heater heating by the 3rd check-valves or enter the second adsorption tower by the 4th check-valves.The air inlet of air blast is then formed by the air inlet of pipeline and first, second adsorption tower and is connected in parallel, and the motor-driven valve that automatically can control break-make is set respectively on two parallel pipelines, the motor-driven valve be wherein connected between the air inlet of air blast and the air inlet of the first adsorption tower is the first motor-driven valve 51, and the motor-driven valve be connected between the air inlet of air blast and the air inlet of the second adsorption tower is the second motor-driven valve 52.
Operationally, two adsorption towers are operated in absorption and reproduced state to dryer of the present utility model respectively, and the operation principle below with regard to two adsorption towers makes specific descriptions:
When the first adsorption tower be operated in adsorbed state, the second adsorption tower be operated in reproduced state time, 3rd motor-driven valve is opened, the compressed air of air inlet pipe enters in the first adsorption tower by the 3rd motor-driven valve from the air inlet of the first adsorption tower, compressed-air actuated moisture is by the sorbent in the first adsorption tower, then, dry compressed air flows out from the gas outlet of the first adsorption tower, and is exported from escape pipe by the first check-valves, thus formation one independently adsorbs gas circuit; Meanwhile, gas is sent from air outlet by air blast, and heater is now opened and run, after the gas heater via heating that air blast is sent, entered in the second adsorption tower from the gas outlet of the second adsorption tower by the 4th check-valves, thus thermal regeneration is carried out to the adsorbent in the second adsorption tower.Then, the gas that temperature reduces flows out from the air inlet of the second adsorption tower, the second motor-driven valve is now in opening, thus flow back into the air inlet of air blast by the second motor-driven valve from the air inlet effluent air of the second adsorption tower, thus forms a closed regeneration gas circuit.Be understandable that, the now first, the 4th motor-driven valve and cooler should be in closed condition.In addition, because the compressed-air actuated pressure in absorption gas circuit will far above the gas pressure carried by air blast in regeneration gas circuit, that is will far above the gas pressure of the regeneration gas circuit near heater side near the gas pressure of the absorption gas circuit of the side, gas outlet of the first adsorption tower on the 3rd check-valves, therefore, the gas sent from air blast can not flow in the first adsorption tower by the 3rd check-valves, the blocking-up that the Compressed Gas that first adsorption tower flows out then is subject to the 3rd check-valves cannot enter in the second adsorption tower by the 4th check-valves, like this, the gas circuit that formation is adsorbed and regeneration two is separate in dryer.In addition, when we close heater and correspondingly open cooler, the gas sent from air blast enters in the second adsorption tower after cooler cooling, thus carries out cold blowing regeneration to the adsorbent in the second adsorption tower, like this, the adsorbent in the second adsorption tower can recover adsorption function again.
When after dryer work certain hour, need to heat the adsorbent in the first adsorption tower and cold blowing regeneration to recover its adsorption function, now the second adsorption tower is operated in adsorbed state, the first adsorption tower is operated in reproduced state.For this reason, we make the 4th motor-driven valve open, the compressed air of air inlet pipe enters in the second adsorption tower by the 4th motor-driven valve from the air inlet of the second adsorption tower, compressed-air actuated moisture is by the sorbent regenerated in the second adsorption tower, then, dry compressed air flows out from the gas outlet of the second adsorption tower, and is exported from escape pipe by the second check-valves, thus formation one independently adsorbs gas circuit; Meanwhile, heater is opened and is run, after the gas heater via heating that air blast is sent, enter in the first adsorption tower by the 3rd check-valves from the gas outlet of the first adsorption tower, thus thermal regeneration is carried out to the adsorbent in the first adsorption tower, then, the gas that temperature reduces flows out from the air inlet of the first adsorption tower, the first motor-driven valve is now in opening, thus flow back into the air inlet of air blast from the air inlet effluent air of the first adsorption tower by the first motor-driven valve, thus form a closed regeneration gas circuit.Be understandable that, second, third motor-driven valve now and cooler should be in closed condition.In addition, as hereinbefore, because the compressed-air actuated pressure in absorption gas circuit will far above the gas pressure having air blast to carry in regeneration gas circuit, that is will far above the gas pressure of the regeneration gas circuit near heater side near the gas pressure of the absorption gas circuit of the side, gas outlet of the second adsorption tower on the 4th check-valves, therefore, the gas sent from air blast can not flow in the second adsorption tower by the 4th check-valves, and the blocking-up that the Compressed Gas that the second adsorption tower flows out then is subject to the 4th check-valves cannot be entered in the first adsorption tower by the 3rd check-valves.In addition, when we close heater and correspondingly open cooler, the gas sent from air blast enters in the first adsorption tower after cooler cooling, thus carries out cold blowing regeneration to the adsorbent in the first adsorption tower, like this, the adsorbent in the first adsorption tower can recover adsorption function again.
In addition, we also make by pipeline to be connected between the gas outlet of first, second adsorption tower, and on this connecting line, be connected in series the 8th motor-driven valve 58 that a manual adjustments flow valve 10 and can control break-make automatically.8th motor-driven valve is in closed condition at ordinary times, thus make first, be spaced from each other between the gas outlet of the second adsorption tower, when we need the duty of switching two adsorption towers, the 8th motor-driven valve can be opened simultaneously, thus make first, be interconnected between the gas outlet of the second adsorption tower, like this, originally be in that gases at high pressure in the adsorption tower place absorption gas circuit of adsorbed state can manually adjust flux valve and the 8th motor-driven valve enter and be originally in the regeneration gas circuit at the adsorption tower place of reproduced state rapidly, the gas pressure of absorption gas circuit is originally reduced rapidly, then we close the 8th motor-driven valve again to cut off the contact between absorption gas circuit and regeneration gas circuit, two adsorption towers complete switching, can restart to carry out adsorption dry to compressed air, the script gas be in the absorption gas circuit of adsorbed state then can be used as the regeneration gas in the regeneration gas circuit after switching.Manual adjustments flow valve then can control the gas flow of this connecting line, thus controls the switch speed of adsorption tower duty.Be understandable that, manual adjustments flow valve only need regulate when dryer runs for the first time, gets final product fixed manual adjust flux valve, its circulation is remained unchanged after adjustment puts in place.
In addition, we also can connect the 5th motor-driven valve 55 and suction filter 11 in the air inlet of air blast by pipeline successively.Like this, when we open the 5th motor-driven valve, the air inlet of air blast is communicated with outside air, and outside air filters totally by suction filter and enters in regeneration gas circuit by the air inlet of air blast, to fill the regeneration gas in regeneration gas circuit.Then close the 5th motor-driven valve, suction filter quits work, and regeneration gas circuit now forms closed gas circuit again, the gas circulating flow in regeneration gas circuit, carries out thermal regeneration or cold blowing regeneration to one of them adsorption tower.
Further, the pipeline of connection first motor-driven valve and blower inlet first can merge with the pipeline being connected the second motor-driven valve and blower inlet and is connected on a main pipe rail by we, then main pipe rail is connected on the air inlet of air blast, like this, we can arrange the 6th motor-driven valve 56 on this main pipe rail, thus can control the break-make regenerating gas circuit easily.Meanwhile, we also otherly on this main pipe rail can connect a noise reduction pipeline, this noise reduction pipeline connect successively the 7th motor-driven valve 57 and a muffler 12.Like this, when dryer is shut down, we can open the 7th and first, second motor-driven valve, so that release absorption gas circuit and the gas in regeneration gas circuit, muffler then can eliminate noise during venting effectively.
