Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description will be provided with reference to specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a compressed air delivery system, which includes an air compressor 21, a cold dryer 31, an air tank 61, and a heating device for heating compressed air, wherein one end of the cold dryer 31 is connected to the air compressor, the other end of the cold dryer 31 is connected to one end of the heating device, and the other end of the heating device is connected to the air tank 61; the temperature of the compressed air flowing out of the cooling dryer 31 is increased after the compressed air passes through the heating device.
According to the compressed air conveying system provided by the embodiment of the invention, the heating device for heating the compressed air is arranged between the cold dryer 31 and the air storage tank 61, so that the compressed air flowing into the heating device from the cold dryer 31 can be heated by the heating device, the temperature of the compressed air flowing out from the heating device is increased, and then the compressed air is conveyed into the air storage tank 61, the temperature of the compressed air output by the compressed air conveying system is better prevented from being too low, and the quality of products is favorably ensured.
Further, the compressed air delivery system provided by the embodiment of the present invention further includes an electric valve 51, and a first temperature sensor 52 is disposed on a pipeline at an air inlet of the air storage tank; the electric valve is connected with the heating device in parallel. By adopting the scheme, according to the temperature value obtained by the first temperature sensor 52, the compressed air flowing out of the refrigeration dryer is divided by adjusting the opening degree of the electric valve, so that the amount of the compressed air flowing into the heating device is adjusted, and the temperature of the compressed air flowing into the air storage tank is adjusted. It can be understood that the electric valve has a function of adjusting the temperature of the compressed air, that is, when the first temperature sensor detects that the temperature of the compressed air is low, the valve of the electric valve 51 is closed or closed by a small opening degree, so that the amount of the compressed air heated by the heating means is increased, and the amount of the compressed air passing through the electric valve is decreased, thereby increasing the temperature of the compressed air entering the air tank; when the first temperature sensor detects that the temperature of the compressed air is higher, the valve of the electric valve is opened or the opening degree of the electric valve is increased, so that the amount of the compressed air heated by the heating device is reduced, the amount of the compressed air passing through the electric valve is increased, and the temperature of the compressed air entering the air storage tank is reduced; meanwhile, if the first heat exchanger fails or needs to be overhauled, the compressed air can flow to the air storage tank from the pipeline where the electric valve is located.
Specifically, the warming device is a first heat exchanger 41, and the first heat exchanger is connected with a cooling water outlet pipeline 17 of the air compressor; the cooling water flowing out of the air compressor flows into the first heat exchanger 41, and exchanges heat with the compressed air flowing into the first heat exchanger, so that the temperature of the compressed air is raised, and the heated compressed air flows to the air storage tank, so that the structure of the heating device is simpler.
Further, a first air outlet is arranged on one side, opposite to the air inlet, of the air storage tank 61, and a second air outlet is arranged at the top of the air storage tank; a water drain valve is arranged at the bottom of the gas storage tank; the top of the air storage tank and the bottom of the air storage tank are both provided with tip structures; an inclined baffle plate 62 opposite to the air inlet is arranged in the air storage tank, and one end, far away from the top, of the inclined baffle plate 62 inclines towards the direction close to the first air outlet; the inclined baffle is provided with a transverse baffle 63 which is horizontally arranged, and the transverse baffle 63 is positioned above the air inlet. Through this scheme, after compressed air got into the gas holder by the income gas port, blow and beat on oblique baffle, because the molecular weight of water is less than the average molecular weight of air and the density of steam is less than the density of air promptly, get into the gas holder, compressed air is under gravity and velocity of flow effect, air among the compressed air will flow downwards along oblique baffle and walk around from oblique baffle bottom and flow out the gas holder by first gas outlet again, and vapor among the compressed air then because density is less, then can rise to the top of gas holder along oblique baffle, the cross slab then can block partial ascending air and cause its downward flow. Therefore, the air storage tank with the structure has the function of separating water vapor and air in the compressed air, so that moisture in the compressed air is separated and removed. It is understood that the number of the transverse baffles may be at least two.
It may be preferable that the top of the gas container 61 has a hemispherical structure or a tapered structure. The bottom of the air reservoir may be of the same construction as the top of the air reservoir. It can be understood that the first air outlet may be communicated with the air dividing cylinder 65, and the compressed air in the air dividing cylinder is conveyed to the workshop through a pipeline for utilization by the air supply device 66; wherein the gas-using equipment represents a plurality of different gas-using equipment; if moisture is accumulated at the bottom of the sub-cylinder, the water can be discharged into the trench through a pipeline at the bottom.
Further, the second air outlet is vertically connected with a second elongated pipeline 72 through a first elongated pipeline 71, and the second elongated pipeline is connected with the second heat exchanger 42; the second heat exchanger is also connected with a cooling water outlet pipe of the first heat exchanger, and a cooling water outlet pipe 43 of the second heat exchanger is used for being connected with a water inlet pipe 18 of the cooling tower; the second heat exchanger has a drain line. By adopting the scheme, the first elongated pipeline and the second elongated pipeline which are vertically connected are arranged, so that water vapor can flow upwards and intensively flow into the first elongated pipeline and the second elongated pipeline, air entering the first elongated pipeline can sink and then flow away again entering the air storage tank, and the purity of the water vapor flowing into the second elongated pipeline from the second air outlet of the air storage tank is higher; and after the water vapor enters the second heat exchanger, because the temperature of the cooling water is reduced after the cooling water passes through the first heat exchanger, the low-temperature cooling water enters the second heat exchanger again, and the water vapor is condensed into water drops after being cooled by the low-temperature cooling water in the second heat exchanger and is discharged into a trench through a drainage pipeline. It is understood that the drain line may include a drain tube 46, a valve disposed on the drain tube, a drain valve 47; the first heat exchanger and the second heat exchanger can be manufactured in a set or installed in a centralized mode, the outer shell 45 is additionally arranged outside, and the outside is only connected with pipelines of other parts through the flange 44, so that the installation space can be saved, and the appearance is more attractive.
Specifically, a second temperature sensor 19 is arranged on an inlet pipe 18 of the cooling tower, a water outlet pipe 12 of the cooling tower is used for being connected with a water tank 13, and the water outlet pipe of the water tank is connected with a cooling water inlet pipeline of the air compressor. By adopting the scheme, if the cooling water passes through the first heat exchanger and the second heat exchanger, the temperature of the cooling water detected by the second temperature sensor meets the cooling requirement of the air compressor, and then the fan of the cooling tower stops running, so that the electric energy is saved, and the cooling tower only naturally cools the cooling water. It can be understood that the circulation path of the cooling water is: after cooling water is cooled by the cooling tower, the cooling water flows into the water tank 13, the cooling water in the water tank can enter the air compressor through the valve 14, the water pump 15 and the check valve 16, the air compressor is cooled by the cooling water, the heated cooling water flows into the first heat exchanger from a cooling water outlet pipeline of the air compressor, the cooling water exchanges heat with low-temperature compressed air in the first heat exchanger, the temperature is reduced, the cooling water with low temperature enters the second heat exchanger, the low-temperature cooling water cools water separated by the air storage tank in the second heat exchanger, and then the cooling water enters the cooling tower for cooling after passing through the second temperature sensor, and the process is repeated.
Furthermore, a bypass water path 191 is arranged between the cooling water outlet pipeline of the air compressor and the cooling water outlet pipe 43 of the second heat exchanger, and a bypass valve 192 is arranged on the bypass water path, so that when the first heat exchanger or the second heat exchanger fails or needs to be overhauled, the bypass valve can be opened, and the cooling water flows back to the cooling tower through the bypass water path after flowing out from the air compressor.
Specifically, a coarse filter 23 and a steam-water separator 25 are sequentially connected between the air compressor and the cold dryer; the bottom of the coarse filter is provided with a first valve 24; a first bypass pipeline connected with the coarse filter in parallel is arranged between the air compressor and the steam-water separator, and a second valve 22 is arranged on the first bypass pipeline, so that dust and impurities in the compressed air are filtered out through the coarse filter.
Further, a fine filter 27 is arranged between the cold dryer and the first heat exchanger, and a third valve 28 is arranged at the bottom of the fine filter; a second bypass pipeline connected with the fine filter in parallel is further arranged between the cold dryer and the second heat exchanger, and a fourth valve 26 is arranged on the second bypass pipeline, so that dust and impurities in the air are filtered through the fine filter. It will be appreciated that the dust and impurities in the coarse filter may be discharged through the first valve and the impurities in the fine filter may be discharged through the third valve; and be provided with first bypass pipeline, the second bypass pipeline that sets up with coarse filter and smart filter parallelly connected respectively, if coarse filter, smart filter break down or need change the filter core like this, for not influencing production, through opening second valve and fourth valve for compressed air can be temporarily carried through first bypass pipeline, second bypass pipeline.
After the air compressor compresses the air into the compressed air, the temperature of the compressed air is higher, and the compressed air contains a large amount of moisture; the compressed air is filtered to remove dust and impurities when passing through the coarse filter and then enters the steam-water separator, as the water vapor in the air is compressed and even condensed after the air is compressed, part of the water in the compressed air is separated by the steam-water separator, the water separated by the steam-water separator is discharged into a trench through a valve and a pipeline at the bottom of the steam-water separator, the water in the compressed air is also contained with a large amount of water vapor after being separated by the steam-water separator, at the moment, the compressed air enters the cold dryer, and the water vapor in the compressed air is condensed into water drops after the temperature of the compressed air is reduced to 4 ℃ through the cold dryer and then is discharged through the bottom of the cold dryer. The temperature of the compressed air after being cooled and drained by the cold dryer is very low, only 4 ℃, although most of moisture is discharged, partial water vapor still exists, and the temperature of the compressed air or the equipment operation and even the product quality are influenced if the low-temperature compressed air is conveyed to a production workshop for direct utilization due to the fact that the compressed air pressure is about 0.7MPa and the flow rate is very high, so that the temperature of the low-temperature compressed air is increased. In the operation process of the air compressor, the air compressor can generate a large amount of heat, the air compressor generates heat through cooling water to absorb the heat, the air compressor is cooled through the cooling tower, and the air compressor is cooled, so that the air compressor is circulated repeatedly. The cooling water after absorbing the heat energy of the air compressor is firstly subjected to heat exchange with low-temperature compressed air through the first heat exchanger, the temperature of the compressed air is increased, the temperature of the cooling water is reduced, the cooling water is cooled through the cooling tower, the temperature of the cooling water is lower, the cooling effect of the air compressor is better, meanwhile, the low-temperature compressed air is heated through the first heat exchanger and then is conveyed to a workshop for utilization, the production environment and equipment are facilitated, the relative humidity of the compressed air is reduced, the quality of the compressed air is higher, and the product quality is more facilitated.
According to the temperature change of the compressed air and the temperature change of the cooling water in the operation of the air compressor, the compressed air is further separated from the residual water vapor in the compressed air at normal temperature or after being regulated to be close to the ambient temperature standard of a production workshop by the cooling water according to the density and the weight difference of the compressed air and the water vapor, the quality of the compressed air is improved, and then the compressed air is conveyed to a rolling and silk-making workshop for utilization, so that the influence of the temperature of the compressed air on equipment and the workshop environment is reduced, the temperature of the workshop is favorably stabilized, the production is favorably realized, the relative humidity of the compressed air is reduced, and the product quality is stabilized.
