Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange equipment and relates to a high-efficiency defoaming device for an air compressor cooler. Background Art

[0002] The main function of an air compressor in an air separation plant is to compress air. This compressed air requires a cooler to cool it, which produces a large amount of condensate. To remove this condensate, various types of demisters or gas-liquid separators are required. For smaller air separation plants, where the gas flow rate is low and the total amount of condensate in the air is relatively small, demisters can be placed close to the tube bundle to effectively remove the condensate. As air separation plants grow larger, such as an 80,000 ton air separation plant, air flow rates reach over 400,000 Nm³ / h and condensate can reach 5 tons / h, making conventional demisters inadequate.

[0003] Therefore, an air compressor cooler high-efficiency defoaming device is designed to overcome the above problems. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide an efficient defoaming device for an air compressor cooler which has a simple structure, is practical and convenient, and has high processing efficiency.

[0006] Preferably, the drainage mechanism is a vertically arranged drainage pipe, the number of which is the same as the number of water retaining grooves, and each drainage pipe is respectively arranged in the middle position of each water retaining groove to drain the condensed water collected in the water retaining groove to the bottom of the cooler shell.

[0007] Preferably, the angle between the demister and the vertically arranged cooler tube bundle is 10 to 15 degrees. This angle facilitates the condensed water to descend, thereby improving the overall defoaming effect.

[0008] Preferably, the bottom of the support frame is provided with telescopic support feet for facilitating angle adjustment and ensuring the stability of the demister.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The purpose of this utility model is to set the demister at a certain distance from the tube bundle, so that a part of the condensed water can fall by gravity, and the demister forms an angle of 10 to 15 degrees with the tube bundle, which also helps the condensed water to fall.

[0011] 2. The utility model divides the demister into multiple layers, and each layer is provided with a water retaining groove to prevent condensed water from flowing into the next layer of wire mesh (the defoaming unit of the next layer), thereby improving the defoaming effect of the overall demister.

[0012] 3. The utility model sets a drainage pipe in the middle of the water retaining groove to drain the condensed water collected in the water retaining groove to the bottom of the cooler shell and discharge it outside the shell, thereby improving the overall practicality.
