The specific embodiment
Be elaborated below in conjunction with the accompanying drawing specific embodiments of the invention.Should be understood that the specific embodiment described herein only is used for explanation and explains the present invention, is not limited to the present invention.
Fig. 1 is the structural representation according to the pressurized air de-watering apparatus of the specific embodiment of the present invention.Following pressurized air de-watering apparatus according to Fig. 1 specific embodiments of the invention is at length explained.
As shown in Figure 1; The pressurized air de-watering apparatus of the specific embodiment of the present invention comprises flash vessel 1, shutoff valve 2 and automatic steam trap 3, and flash vessel 1 is the cylinder of closed at both ends, and the middle part of this cylinder is provided with compressed air inlet pipe 4; Top is provided with pressurized air fairlead 5; The bottom is provided with coolant outlet pipe 6, and coolant outlet pipe 6 is connected in an end of shutoff valve 2, and the other end of shutoff valve 2 is connected with automatic steam trap 3.
The pressurized air that has moisture that comes from air compressor or storage tank enters into flash vessel 1 through compressed air inlet pipe 4; Fully fully collision on the wall of flash vessel 1 after the dilatation; Gas, water carry out gravity separation; Moisture after the separation is deposited in the bottom of flash vessel 1 and from automatic steam trap 3, gets rid of, and does not then draw and get into strength transmission pump (not shown in figure 1) to fail grey operation from the pressurized air fairlead 5 on flash vessel 1 top with the pressurized air of moisture.This pressurized air de-watering apparatus can greatly reduce compressed-air actuated water amount, thereby reduces the problems such as the dust stratification that makes moist, corrosion and stifled ash of equipment in the Pneumatic ash conveying system, makes simply, and cost is low, and maintenance is few.
The structure of flash vessel 1 can be the cylindrical structure of closed at both ends.In addition, in order to guarantee that fully dilatation is so that can fully separate by aqueous vapor in flash vessel 1 for pressure gas, the flash vessel 1 of cylindrical structure must keep the good whole leak tightness.
