Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gas/solid/liquid separation device, and is particularly suitable for gas/solid/liquid separation equipment used for cooling vehicle equipment. It is related to the device.

[Conventional technology]

For vehicles running in snowy, rainy areas, or dusty atmospheres, if air containing lightning, rain, or dust is used to cool equipment such as the traction motor, accidents may occur due to poor insulation, etc. Therefore, it was necessary to remove snow, rain, dust, etc. from the air being taken in. Therefore,
thunder or rain.

A gas/solid/liquid separator is used in which air containing dust, etc. is passed through a curved duct at high speed, and foreign matter such as lightning or dust is removed by centrifugal force. (For example, Patent No. 1024878) [Problem to be solved by the invention] In the above gas and solid/liquid separation device, a part of the air that has been sucked into the curved duct and from which foreign substances have been removed is supplied to the ejector, The separated foreign matter was discharged by the suction action generated by the air. This ejector discharges foreign matter from a curved duct with negative pressure, and a predetermined amount or more of air for FFI must be secured at all times. In particular, when eliminating lightning, a large amount of air was required due to its specific gravity. The remaining air from which the foreign matter has been removed is supplied to the equipment to be cooled through the duct. By the way, the distribution ratio of the air from which the foreign matter M has been removed is used for exhausting foreign matter and for cooling the equipment. On the other hand, in the summer when the temperature is high, the temperature of electrical equipment rises, and a large amount of air is needed to cool it down. Currently, because the temperature is low, the amount of cooling air can be relatively small. therefore,
In the above-mentioned conventional technology, sufficient consideration was not given to the distribution of the sucked air.

An object of the present invention is to provide a gas and solid/liquid separation device that can operate efficiently by changing the ratio of the air used for expelling foreign matter to the sucked air. .

[Means for solving problems]

The above purpose is to provide a temperature detector that detects the outside air temperature sucked into the device, a distribution means that can change the ratio of air supplied to the ejector and other equipment, and a control input that uses the detection results of the temperature sensor as a control input. This is achieved by comprising a controller that controls the distribution means so as to increase the amount of air supplied to the other equipment when the temperature is high.

[For production]

The controller increases the amount of air supplied to other devices by one distribution means under conditions where the outside temperature is high and there is no snowfall,
Under conditions where the outside temperature is low and there is snowfall, the amount of air supplied to the ejector by the distribution means is increased to improve the ability to eject snow, etc., so that efficient operation can be performed.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the same figure, l is outside air 9 (indicated by an arrow)
2 is a curved duct into which the outside air 9 sucked from the suction grill 1 is introduced, and foreign matter 8 such as snow contained in the outside air 9 is removed by centrifugation. The force causes it to move toward the outer periphery. Reference numeral 3 designates a separation duct that is open and installed on the outer circumference side at the terminal end of the curved duct 2, and reference numeral 4 represents a discharge duct that is connected to an ejector 5 that is installed at a uniform interval on the outer circumference of the other end of the separation duct 3. 6 is clean air 10 from which foreign matter 8 has been removed by the curved duct 2;
A chamber (indicated by an arrow) is guided by the feeder La7, in which the ejector 5 is arranged, and a part of the clean air 10 in the chamber 6 is used to drive the ejector 5, that is, to generate an attractive force. Used for. A cooling air passage 11 is connected to the chamber 6 and supplies clean air 10 excluding air for driving the ejector 5 for equipment cooling. The hill is a curved duct 2
a temperature detector installed on the suction side of the
A static pressure detector 14 is installed in the cooling air passage 11 and detects its static pressure. A damper 13 is arranged in the chamber 6 and serves as a wind fit adjustment means for adjusting the amount of air supplied from the air blower 7 to the ejector 5. Next, 15 is the temperature sensor and the static pressure sensor 1.
This is an interface for inputting the detection results of step 4 to the microprocessor 17. Note that the microprocessor 17 determines whether the temperature of the outside air 9 is higher or lower than a set value (temperature corresponding to the snowfall state), and if it is higher, the temperature of the outside air 9 is
This outputs a control command to the damper 13 to reduce the amount of air supplied to the ejector 5;
A control command is output to increase the amount of air supplied to the ejector 5. An interface 16 is also provided between the microprocessor 17 and the damper 13. By the way, the static pressure detector 14 detects the pressure inside the cooling air duct 11 and sends it to the microprocessor 17, and the microprocessor 17 determines whether the control state of the damper 13 corresponds to the static pressure inside the cooling air duct 11. This is to constantly check whether the mutual relationship is operating normally.

According to such a configuration, when the temperature of the outside air 9 drops to a state corresponding to snowfall, the damper 13 is brought closer to the state shown by the dotted line in the figure, and the amount of air supplied to the ejector 5 is increased to remove the foreign matter 8. The exhaust can be efficiently carried out, and the amount of foreign matter 8 mixed into the clean air 10 can be suppressed to at least one.

-10,000, If the temperature of outside air 9 is higher than that during snowfall, damper 1
3 is maintained in the state shown by the solid line, n, and supplies the minimum amount of air necessary for driving the ejector 5, thereby increasing the amount of clean air 10 supplied to the cooling air passage 11.

Due to this, the temperature of the outside air 9 is low and the temperature of the equipment to be cooled is also relatively low 1, for example, in winter.

Foreign objects 8, especially those containing lightning, can be ejected by the ejector 5 with improved efficiency. Therefore, the appearance of the foreign matter 8 contained in the clean air 10 can be minimized, and in particular, problems such as poor insulation of the Onomichi machine caused by the presence of snow can be prevented.

In addition, by adjusting the distribution amount of air supplied to the ejector 3 and the equipment to be cooled as described above, the air blow a
7, the amount of air taken in can be reduced, and the size of the blower 7 or the required power can be reduced. Furthermore, noise reduction can also be achieved.

〔Effect of the invention〕

As explained above, according to the present invention, efficient operation can be performed in a gas and solid/liquid separation device.
