Description

Technical Field

[0001] The utility model relates to the technical field of air compressor drying equipment, in particular to a new air compressor drying and processing system. Background Art

[0002] After-treatment drying of air compressors generally uses adsorption dryers or refrigeration dryers. Adsorption dryers have a low dew point and good drying effect, but high energy consumption and high maintenance costs. Refrigeration dryers have a high dew point but low energy consumption and low maintenance costs, so they are widely used.

[0003] Currently, when the existing air compressor drying and processing system is in operation, generally, the air compressor blows air into the air storage tank for storage, and then the air in the air storage tank is directly introduced into the workshop for use after being dried by the refrigeration dryer. However, due to the relatively high (pressure) dew point (2 - 10°C) of the refrigeration dryer, when the ambient temperature or the intake air temperature is high, it is easy to cause the dew point to rise, resulting in condensed water in the compressed air at the gas-using end. The condensed water is likely to damage the products or production equipment, affecting the service life of the production equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, including: an air compressor; a heat exchanger, the heat exchanger is connected to the air outlet end of the air compressor through a first conduit; an air storage tank, the air inlet end of the air storage tank is connected to the heat exchanger through a second conduit; a refrigeration dryer, the air inlet end of the refrigeration dryer is connected to the air outlet end of the air storage tank through a third conduit, and the air outlet end of the refrigeration dryer enters each gas-using equipment in the workshop through the heat exchanger after heat exchange through a fourth conduit.

[0005] As a further description of the above technical solution: a first drain valve is arranged below the air storage tank, and the first drain valve is connected to a drain pipe.

[0006] As a further description of the above technical solution: a second drain valve is arranged below the refrigeration dryer, and the second drain valve is connected to a drain pipe.

[0007] As a further description of the above technical solution: a first filter is arranged on the third conduit, and the first filter is connected to a drain pipe.

[0008] As a further description of the above technical solution: a second filter and a third filter are arranged on the fourth conduit, and both the second filter and the third filter are connected to a drain pipe.

[0009] The above technical solution has the following advantages or beneficial effects:

[0010] In the post-treatment system of the air compressor, a heat exchanger is installed in the present utility model to conduct heat exchange between the low-temperature compressed air coming out of the refrigerated dryer and the high-temperature compressed air coming out of the air compressor. After the temperature of the high-temperature compressed air coming out of the air compressor is reduced, it enters the air storage tank to remove a large amount of condensed water and then enters the refrigerated dryer for drying. This can greatly reduce the heat and moisture load of the refrigerated dryer, lower the dew point temperature of the refrigerated dryer, make the compressed air in the workshop less likely to generate condensed water, improve the drying efficiency of the refrigerated and dried air compressor system, effectively reduce the probability of condensed water generated by the compressed air at the user end, reduce the energy consumption of the refrigerated dryer, reduce the heat loss of the compressed air, and also reduce the failure rate of each device in the system.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0015] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0016] In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and defined, the terms "arranged", "set", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0017] As Figure 1 shown, a novel air compressor drying and processing system of the present utility model includes: an air compressor 1; a heat exchanger 2, the heat exchanger 2 is connected to the air outlet end of the air compressor 1 through a first conduit 5; a gas storage tank 3, the air inlet end of the gas storage tank 3 is connected to the heat exchanger 2 through a second conduit 6; a cold dryer 4, the air inlet end of the cold dryer 4 is connected to the air outlet end of the gas storage tank 3 through a third conduit 7, and the air outlet end of the cold dryer 4 enters each gas-using device in the workshop through the fourth conduit 8 after heat exchange through the heat exchanger 2.

[0018] In this embodiment, the high-temperature and high-humidity compressed air produced by the air compressor 1 enters the heat exchanger through the first conduit 5, exchanges heat with the low-temperature compressed air cooled by the cold dryer 4 in the heat exchanger 2 to become medium-temperature compressed air and enters the gas storage tank 3. The medium-temperature compressed air with reduced moisture content reaches the air inlet end of the cold dryer 4 through the third conduit 7 from the air outlet of the gas storage tank 3. The low-temperature compressed air output by the cold dryer 4 enters the heat exchanger 2 through the fourth conduit 8. The low-temperature compressed dry air exchanges heat with the high-temperature and high-humidity compressed air coming out of the air compressor 1. Because the specific heat capacity of the low-temperature dry compressed air is much smaller than that of the high-temperature and high-humidity compressed air, the temperature of the low-temperature dry compressed air after heat exchange rises to almost the same temperature as the high-temperature and high-humidity compressed air and is output from the air outlet of the heat exchanger 2. The high-temperature dry compressed air after heat exchange is output to each gas-using device in the workshop through the air compressor pipeline.

[0019] By adopting a freeze-dried air compression system, the temperature of the compressed air after the compressed air passes through the cold dryer 1 for condensation and dehydration is about 15-20°C lower than the temperature of the intake air. The present invention is to add a heat exchanger 2 in the air compression post-processing system to heat exchange the low-temperature compressed air from the cold dryer 4 with the high-temperature compressed air from the air compressor, and then lower the temperature of the high-temperature compressed air from the air compressor 1 and enter the air storage tank 3 to remove a large amount of condensed water before entering the cold dryer 4 for drying, which can greatly reduce the heat and humidity load of the cold dryer 4 and reduce the dew point temperature of the cold dryer 4; the compressed air dried by the cold dryer 4 passes through the heat exchanger 2 and absorbs the heat of the high-temperature compressed air from the air compressor 1, and the temperature rises, which improves the energy of the compressed air and also increases the difference between the temperature and pressure dew point of the compressed air, so that the compressed air in the workshop is not easy to produce condensed water. The present invention improves the drying efficiency of the freeze-drying air compressor system, effectively reduces the probability of condensed water generated by the compressed air at the user end, and at the same time reduces the energy consumption of the cold dryer, reduces the heat loss of the compressed air, and also reduces the failure rate of various equipment in the system.

[0020] Specifically, the system's water removal capacity is improved and the compressed air dew point is reduced: the system adds a heat exchanger to fully recover the cold air of the cold dryer to pre-cool the high-temperature compressed air coming out of the air compressor 1, which greatly reduces the air intake temperature and moisture content of the cold dryer, reduces the load of the cold dryer, and thus reduces the dew point of the outlet air; reduces system energy consumption: because the heat and moisture content of the compressed air entering the cold dryer 4 is reduced, the load of the cold dryer is reduced, and the energy consumption is reduced by about 5-10%. At the same time, the heat exchanger 2 increases the outlet temperature of the cold dryer 4, increases the pressure and heat of the compressed air entering the workshop, improves the compressed air blowing efficiency and the workmanship of pneumatic tools, and indirectly reduces energy consumption; optimizes the system condensate discharge: the heat exchanger 2 added by the present invention pre-cools the compressed air temperature coming out of the air compressor 1, so that the saturated wet air condenses more condensate in the air storage tank 3 than the existing system, thus greatly reducing the condensate discharge of the subsequent filter and cold dryer 4, so that the filter and cold dryer 4 can give full play to their efficiency and reduce the failure rate and maintenance frequency. Improved system reliability: The temperature of the compressed air entering the filter and cold dryer 4 is reduced, and the amount of condensed water is reduced, which reduces the failure rate of the cold dryer 4 and extends the service life of the filter element. The low failure rate and low maintenance frequency improve the reliability of the system.

[0021] Among them, when the system is just started, there is no low-temperature dry compressed air in the fourth conduit 8, which does not affect the subsequent work of the system. After the system has worked for a period of time, it can operate stably. The cold dryer 4 cools and removes water. The main function of the heat exchanger 2 is to pre-cool the compressed air temperature coming out of the air compressor 1 and increase the thermal energy of the compressed air in the workshop.

[0022] like Figure 1As shown in the figure, specifically, a first drain valve 9 is provided below the gas storage tank 3, and the first drain valve 9 is connected to the drain pipe 11; the low-temperature compressed air cooled by the refrigerated dryer 4 exchanges heat in the heat exchanger 2 and then becomes medium-temperature compressed air (the temperature is reduced by about 15°C) and enters the gas storage tank 3. A large amount of water vapor in the cooled compressed air condenses and flows into the bottom of the gas storage tank 3 and is discharged into the drain pipe 11 by the first drain valve 9.

[0023] As Figure 1 shown in the figure, specifically, a second drain valve 10 is provided below the refrigerated dryer 4, and the second drain valve 10 is connected to the drain pipe 11; the air entering the refrigerated dryer 4 from the gas storage tank 3 is output from the air outlet end of the refrigerated dryer 4 after being dehumidified by freezing in the refrigerated dryer 4, and the condensed water is discharged into the drain pipe 11 by the second drain valve 10.

[0024] As Figure 1 shown in the figure, specifically, a first filter 12 is provided on the third conduit 7, and the first filter 12 is connected to the drain pipe 11; the medium-temperature compressed air with reduced moisture content passes through the first filter 12 from the air outlet of the gas storage tank 3 to remove condensed water, solid particles, dust, and sundries and reaches the air inlet end of the refrigerated dryer 4.

[0025] As Figure 1 shown in the figure, specifically, a second filter 13 and a third filter 14 are provided on the fourth conduit 8, both the second filter 13 and the third filter 14 are connected to the drain pipe 11, and drain valves are provided on the first filter 12, the second filter 13, and the third filter 14; the low-temperature compressed air output from the refrigerated dryer 4 passes through the second filter 13 and the third filter 14 to remove condensed water, fine particles, and oil mist again and then enters the heat exchanger 2.

[0026] Working principle: By adopting a refrigerated air compressor system, the temperature of the compressed air after condensation and water removal by the refrigerated dryer 1 is about 15 - 20°C lower than the inlet temperature. The present invention installs a heat exchanger 2 in the post-treatment system of the air compressor to exchange heat between the low-temperature compressed air from the refrigerated dryer 4 and the high-temperature compressed air from the air compressor. The high-temperature compressed air from the air compressor 1 is cooled and then enters the gas storage tank 3 to remove a large amount of condensed water and then enters the refrigerated dryer 4 for drying, which can greatly reduce the heat and moisture load of the refrigerated dryer 4 and lower the dew point temperature of the refrigerated dryer 4; the compressed air dried by the refrigerated dryer 4 absorbs the heat of the high-temperature compressed air from the air compressor 1 after passing through the heat exchanger 2 and then the temperature rises, which not only improves the energy of the compressed air but also increases the temperature difference between the temperature and the pressure dew point of the compressed air, making it difficult for condensed water to be generated in the compressed air in the workshop. The present invention improves the drying efficiency of the refrigerated air compressor system, effectively reduces the probability of condensed water generation in the compressed air at the user end, reduces the energy consumption of the refrigerated dryer, reduces the heat loss of the compressed air, and also reduces the failure rate of each device in the system.
