Abstract

PURPOSE: To clean compressed air by employing a relatively long pipe and a specified number of new air dryer and specifying the value of the volume ratio of a small capacity and a large capacity receiver tanks. CONSTITUTION: Compressed air discharge out of a compressor 1 can have a temperature inclination to approximately the ambient temperature due to natural heat radiation by a relatively long pipe 2 and after further cooled, the air is led to a small capacity receiver tank 3 to stabilize the static pressure of a container at the time of supply. The small capacity receiver tank 3 is brought into directly with a large capacity receiver tank 6 through wall faces with high thermal conductivity and the temperature lowering effect is further carried out by thermal conduction to the large capacity receiver tank 6. The internal volume ratio of the small capacity receive tank 3 and the large capacity receiver tank 6 is set to be about 2:8. The resultant air is led to two new air dryers 4, 5 installed in series in order to be dried air with lowered dew point. After that, the dried compressed air is led to the large capacity receiver tank 6, heated to lower the saturation degree of humidity and make it difficult to form dew drops, and then supplied to a use terminal.

Description: FIELD OF THE INVENTION The present invention relates to a system for cleaning compressed air in a vehicle and its equipment. 2. Description of the Related Art The conventional equipment for removing impurities (water, oil, dust) from compressed air in vehicles is simply equipped with an air-cooled aftercooler to lower the hot exhaust gas of the compressor to the ambient temperature, and chemical adsorption at the rear part. The agent was installed to remove water and dried. The chemical adsorbent that plays the role of this dryer was not suitable for continuous operation and had a problem of rapid performance deterioration, but in order to minimize this performance deterioration, an electrically controlled mechanical reverse blow system was used. I was collecting. This series of systems has the following general problems. Even if a reverse blow system is adopted, the life of the function body is only a fraction of that of a refrigeration air dryer, and the pressure loss increases as the load increases, and the performance decreases in proportion to it. , When the oil of the compressor adheres to the functional parts, the performance deteriorates rapidly (the oil removal at high temperature is currently technically difficult.), And the electrically controlled mechanical air blow system has a very large number of parts. However, because of the high failure rate and the limited space inside the vehicle, the volumetric efficiency of the device is important, but it was not satisfactory compared to the same model on land. , System maintenance (aging and management of differential pressure) and adsorbent replacement costs were enormous costs that went against labor saving. With respect to the above problems, the present invention has been completed as a result of many years of experiments and consideration. Means for Solving Problems This application is to give priority to the safety of various things in the vehicle first, and without using any chemical adsorbent, electric control, mechanical control medium and system, etc., to naturally radiate heat to the atmosphere. With a system that utilizes only the change in the density of compressed air due to aeration and ventilation, it has achieved the removal of impurities with a performance similar to that of adsorbent. The compressed air discharged from the compressor of the action diagram I is
Due to the natural heat dissipation of the long pipe, a temperature gradient can be taken up to almost the ambient temperature, and it enters the small-capacity receiver tank. In this tank, the temperature is further reduced and at the same time the static pressure inside the vessel is stabilized. In order to obtain a low dew point of ΔT = −20 ° C. or higher from room temperature, it is dried with two new air dryers. The dried compressed air is
The large-capacity receiver tank is heated and supplied to the end of use. EXAMPLE Compressed air discharged from the compressor of FIG.
The temperature gradient can be taken up to almost ambient temperature by natural heat dissipation of the pipe which is longer than the conventional one. Put it in a receiver tank to make it deterministic and to stabilize the static pressure inside the vessel during supply. This receiver tank is in direct contact with the large-capacity receiver tank by the wall surface with high thermal conductivity, and further increases the temperature reduction effect by heat transfer from the tank. In addition, the internal volume ratio of the tank is set to 2: 8, which is to make the flow rate of the new air dryer, which will be described later, constant when the compressed air in the tank is overloaded or at a small load (static pressure stabilization). The purpose is to improve the performance of this system. Drainage is discharged out of the tank by a solenoid valve. Then enter the new air dryer installed in series to make the dry air with a lower dew point. The internal structure of this new air dryer is as follows and fulfills the dehumidifying function. The compressed air that has entered from the inlet of FIG. II changes its direction in the U-shaped cylinder in the horizontal direction and rotates. This rotated air is jetted vertically downward by the nozzle. Rotate the inside of the cylinder with the nozzle of. At this position in the cylinder, Karman vortices are generated on the wall surface to separate impurities and push them downward.
Since the central part of the inside of the cylinder is clean air, in consideration of kicking up of water droplets, air is extracted from the central part to the outside of the device. Impurities are discharged from the pot to the outside of the container. With the above structure of the new air dryer, the compressed air can have a lower dew point than the receiver tank of, but the dryness is being sought further from the safety of the equipment at the end of use in the vehicle. After that, I entered a new air dryer installed in series. By entering these two new air dryers, the dryness can be stably extracted to the same extent as the chemical adsorbents used conventionally. Generally, the dehumidifying equipment functions in relation to static pressure, but the new air dryer can stabilize the static pressure near the new air dryer even when there is a large flow rate fluctuation on the downstream side. It will also contribute to stabilizing the performance of the air dryer.
Since this new air dryer functional part is basically only a nozzle and a cylinder, it does not change with time for many years.
The dry air whose dew point was lowered by two new air dryers enters the large capacity receiver tank. Since the temperature of the air in the tank is lower than that of the small-capacity receiver, heat is exchanged with the adjacent wall described above, that is, heating is performed, and the degree of saturation is reduced. It is difficult to form water drops and is supplied to the end of use. EFFECTS OF THE INVENTION According to the present invention, compressed air in a vehicle can easily obtain a low dew point such as a chemical adsorbent more easily than conventional systems without maintenance for many years.
In addition, this system has no moving parts as shown in Fig. II, and functions only by heat radiation, rotation, and injection of air, and since there is no place that rapidly erodes, difficult replacement parts replacement cost and maintenance The cost is greatly reduced. Initial costs such as product costs and equipment costs will also be significantly reduced. In terms of vehicle safety, the number of parts is one tenth of that of conventional products, that there are no moving parts, that there is no electrical control, and performance degradation is one tenth of that of conventional products. Therefore, this safety is epoch-making. Moreover, the recent labor saving and space saving in the vehicle are remarkable, but the present invention requires no maintenance, several times the volume efficiency, and a fraction of the weight, and the compressed air in the future of the vehicle It is no exaggeration to say that it will change the basic design.
