Description

Technical Field

[0001] The utility model belongs to the technical field of air compressors, and in particular relates to a condensate discharge device for a gas cooler. Background Art

[0002] During the operation of the compressor, the temperature and pressure of the air increase after being compressed by the first-stage compressor. If the compressed air enters the second-stage compressor directly without cooling, the volume of the high-temperature gas will be larger than that after being cooled and then entering the second-stage compressor. Therefore, a larger compressor working volume size is required, and higher requirements are placed on the compressor materials. At the same time, it will also cause the compressor energy consumption to increase and the efficiency to decrease.

[0003] Condensate may form in the compressed air after cooling, and the condensate needs to be discharged from the gas cooler in time, otherwise it will flood the heat exchange tubes, resulting in poor cooling effect of the heat exchanger and even water in the compressor volute, causing immeasurable safety hazards.

DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, a condensate discharge device for a gas cooler comprises a cylinder 1, which is fixed to the ground by a fixing frame 10; a partition 2 is arranged in the middle of the cylinder 1, and the partition 2 divides the cylinder 1 into two chambers, namely an IC1 condensate storage tank 11 and an IC2 condensate storage tank 12, the IC1 condensate storage tank 11 is connected to a primary gas cooler 3, the IC2 condensate storage tank 12 is connected to a secondary gas cooler 4, the primary gas cooler 3 is connected to a primary compressor 24, and the secondary gas cooler 4 is connected to a secondary compressor 25; An ejector 5 is arranged between the IC1 condensate storage tank 11 and the IC2 condensate storage tank 12, a first discharge pipe 6 is arranged at the bottom of the IC1 condensate storage tank 11 and is connected to the suction port of the ejector 5, a second discharge pipe 7 is arranged at the lower part of the side wall of the IC2 condensate storage tank 12 away from the IC1 condensate storage tank 11 and is connected to the nozzle of the ejector 5, and an electromagnetic switch valve 8 is arranged at the discharge port of the ejector 5, which cooperates with the liquid level switch 9 arranged on the top wall of the IC2 condensate storage tank 12 to control the discharge of condensate in the IC1 condensate storage tank 11 and the IC2 condensate storage tank 12.

[0018] It can be understood that usually the primary gas cooler (IC1) and the secondary gas cooler (IC2) are each equipped with a separate condensate discharge device, which has a complex structure. The present application combines the two condensate discharge devices into one, and uses a partition 2 to divide the cylinder 1 into two independent chambers for storing the condensate generated by the primary gas cooler 3 and the secondary gas cooler 4, making the entire device structure more compact and the pipeline more concise.

[0019] Specifically, the top wall of the IC1 condensate storage tank 11 is provided with a first liquid level transmitter 13 and a first gas balance pipe interface 14, the upper part of the side wall of the IC1 condensate storage tank 11 is provided with a first condensate pipe interface 15, the first gas balance pipe interface 14 is connected to the side wall of the primary gas cooler 3 through the first gas balance pipe 16, and the first condensate pipe interface 15 is connected to the bottom of the primary gas cooler 3 through the first condensate outlet pipe 17. The top wall of the IC2 condensate storage tank 12 is also provided with a second liquid level transmitter 18 and a second gas balance pipe interface 19, the upper part of the side wall of the IC2 condensate storage tank 12 is provided with a second condensate pipe interface 20, the second gas balance pipe interface 19 is connected to the side wall of the secondary gas cooler 4 through the second gas balance pipe 21, and the second condensate pipe interface 20 is connected to the bottom of the secondary gas cooler 4 through the second condensate outlet pipe 22. Since the amount of condensate in the IC2 condensate storage tank 12 is usually greater than the amount of condensate in the IC1 condensate storage tank 11, and the pressure in the IC2 condensate storage tank 12 is greater than the pressure in the IC1 condensate storage tank 11, a check valve 23 is provided on the first discharge pipe 6 to prevent the condensate in the IC2 condensate storage tank 12 from flowing back into the IC1 condensate storage tank 11 under the action of the pressure difference.

[0020] It can be understood that the present application monitors the liquid level in the IC1 condensate storage tank 11 through the first liquid level transmitter 13, monitors the liquid level in the IC2 condensate storage tank 12 through the second liquid level transmitter 18, and the liquid level switch 9 is used to issue instructions to open and close the electromagnetic switch valve 8 (the control relationship between the liquid level switch 9 and the electromagnetic switch valve 8 is the prior art and will not be repeated here).

[0021] like Figure 3 As shown, the ejector 5 includes a nozzle 51, a mixing chamber 52 and a diffuser discharge pipe 53. The nozzle 51 and the diffuser discharge pipe 53 are respectively arranged on both sides of the mixing chamber 52. The mixing chamber 52 is provided with a condensate suction port connected to the first discharge pipe 6. A discharge pipe 54 is arranged on the other side of the diffuser discharge pipe 53, and the electromagnetic switch valve 8 is arranged on the discharge pipe 54.

[0022] When the liquid level in the IC2 condensate storage tank 12 reaches the high point H, the liquid level switch 9 issues a command to open the electromagnetic switch valve 8 for drainage. The condensate in the IC2 condensate storage tank 12 flows into the nozzle 51 of the ejector 5 as working water under pressure, forming a high-speed jet in the mixing chamber 52 so that a certain negative pressure is formed in the mixing chamber 52. At this time, the condensate in the IC1 condensate storage tank 11 is sucked into the mixing chamber 52 under the action of the pressure difference. The two condensate flows are mixed and flow into the diffuser discharge pipe 53 and then discharged through the discharge pipe 54. When the liquid level in the IC2 condensate storage tank 12 reaches the low point L, the liquid level switch 9 issues a command to close the electromagnetic switch valve 8 to stop the discharge of condensate.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
