Description

A compressor aftercooler with integrated water separation device

technical field

The invention relates to the technical field of heat exchange equipment, in particular to a compressor rear cooler integrated with a water separation device.

Background technique

In many industrial production or civil fields, it is often necessary to use compressed air. Generally, an air compressor sucks air from an open environment and compresses it into a sealed compressed air storage tank for standby. According to the laws of physics, the temperature of the air will rise significantly after being compressed, and the high-temperature compressed air does not meet the requirements for use and cannot be used directly. The traditional method is to install a cooler behind the air compressor to lower the temperature of the compressed air before using it. However, as the temperature of compressed air decreases, it quickly reaches the dew point (the temperature at which the partial pressure of water vapor in the gas reaches saturation and forms dew), and the water vapor in the air atomizes and condenses, forming a large number of tiny water droplets. To achieve the purpose of using compressed air, it is necessary to remove these tiny water droplets while cooling down.

The existing technology is to build a moisture separator on the air outlet side of the compressed air cooler, which is generally realized in the following three ways. The first method is to arrange wire mesh on the lower part of the cooler outlet side, and use the surface tension of the wire mesh to prevent the water flowing out of the cooler from being carried out by the compressed air. Compressed air water is taken away directly. The disadvantage of this method is that the water separation efficiency is low, and some condensed water will be carried away from the wall of the head by the high-speed compressed air. The second way is to set a large-diameter space at the outlet of the cooler. When the compressed air flows through the space, the flow rate of the compressed air is significantly reduced, thereby reducing the ability of the compressed air to carry water droplets, and the water droplets are separated by gravity. The disadvantage of this method is that the cooler is bulky and inconvenient to install. The third way is to build a corrugated plate water separator in the head of the outlet side of the cooler. The disadvantages are large flow resistance, complex structure and process, and high cost.

Contents of the invention

In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a compressor rear cooler integrated with a water separation device, so that the structure is simple, the efficiency of water separation is improved, and the flow resistance is reduced.

The technical scheme adopted in the present invention is as follows:

A compressor rear cooler with an integrated water separation device, including a plate-fin core body, two ends of the plate-fin core body are respectively equipped with a head, an air outlet is installed on the head of one end, and a bottom of the head is installed Drain outlet, air inlet is installed on the head at the other end, and a water separation device is installed inside the head with the air outlet. The structure of the water separation device is: a baffle is installed inside the head facing the air outlet , A water separation plate is installed inside the head.

Its further technical scheme is:

The air outlets are distributed on the bottom, side, top or end of the sealing head.

The air outlets are distributed at the end of the head, and the baffle is a straight plate, installed obliquely inside the head, and forms an angle with the plate-fin core.

The water separation plate adopts a bent structure, including a vertical side and a horizontal side, and small holes are opened on the vertical side and the horizontal side; the vertical side is arranged obliquely, and the top of the vertical side is in close contact with the inner wall of the head. The distance between the inner walls of the bottom head of the vertical side.

The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

As shown in Fig. 1, Fig. 2 and Fig. 3, the compressor rear cooler of the integrated water separation device of this embodiment includes a plate-fin core body 3, and one end of the plate-fin type core body 3 is installed with a left head 1, The other end is installed with the right head 4, the bottom of the left head 1 is equipped with a drain port 6, the left head 1 is equipped with an air outlet 7, the right head 4 is equipped with an air inlet 5, and the left head 1 is equipped with a Water separation device, the structure of the water separation device is: a baffle plate 2 is installed inside the left head 1 facing the air outlet 7, and a water separation plate 8 is installed inside the left head 1.

As shown in FIG. 1 , FIG. 9 , FIG. 10 and FIG. 11 , the air outlets 7 are distributed on the bottom, side, top or end of the left head 1 .

The air outlets 7 are distributed on the bottom, side or top of the left head 1, and the air outlets 7 are arranged at the center of the left head 1 in the width direction, or close to the center of the width direction of the head. Being in the center is the best location.

As shown in Figure 12, the air outlet 7 is distributed at the end of the left head 1, and the baffle plate 2 is a straight plate installed obliquely inside the left head 1 and forms an angle with the plate-fin core 3.

As shown in Figure 4 and Figure 5, the water separation plate 8 adopts a bent structure, including a vertical side 801 and a horizontal side 802, and small holes 803 are opened on the vertical side 801 and the horizontal side 802; the vertical side 801 is arranged obliquely, and the vertical side The top of 801 is in close contact with the inner wall of the left head 1 , and the bottom of the vertical edge 801 is separated by a distance from the inner wall of the left head 1 .

The vertical side 801 is arranged obliquely, forming an included angle with the vertical center line.

The water separation plate 8 is provided with a through hole 804 for the air outlet 7 .

As shown in Fig. 6, Fig. 7 and Fig. 8, the baffle plate 2 is formed into a "V"-shaped structure with a large opening angle, a "W"-shaped structure with a large opening angle, or a "V"-shaped structure with a large opening angle plus two straight sides.
