Description

Technical Field

[0001] This utility model relates to the field of condensate recovery technology, and in particular to a condensate recovery device for an air compressor. Background Technology

[0002] Currently, the air compressors used by major oil refining, chemical, high-tech materials, and air separation companies are all isothermal compression compressors. Therefore, air compressors are generally equipped with coolers between each compression stage and at the end stage. As we all know, air contains a certain amount of moisture, but more than half of this moisture is removed in the interstage cooler of the air compressor.

[0003] The current drainage solution for air compressor coolers is generally to install a float-type drain valve at the bottom of each cooler. However, if the float-type drain valve malfunctions or fails to drain in time, it is very likely to cause liquid slugging in the air compressor blades. This can result in equipment vibration and shutdown, or even rotor failure. On the other hand, using the bottom direct discharge method will cause drawbacks such as high compressed air loss, high noise, poor condensate recovery, and excessive humidity in the air near the equipment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a chemical equipment waste gas treatment device with the advantages of easy replacement and simultaneous cleaning, thus solving the problem of the cumbersome process of replacing the pretreatment filter unit mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: This utility model provides a condensate recovery device for an air compressor, including a cooler, a primary ejector, a secondary ejector, a water tank 1, a water tank 2, and a circulation pool, all configured between the compression stages of the air compressor. Each cooler has a condensate drain line at its bottom, with a drain valve located near the cooler on each drain line. Each drain line downstream of the drain valve has a float-type drain valve positioned horizontally upwards, with its end connected to water tank 1. Except for the final stage cooler, each drain line upstream of the float-type drain valve has a downward branch, with a float-type drain valve on each branch, and the end of each branch connected to water tank 1. First, the drain line before the float-type drain valve of the final stage cooler has a branch line on the side, and a check valve and valve three are installed in sequence on the branch line. The drain line after valve three is divided into two branches. One branch line is connected to the first inlet of the first stage jet jet and is equipped with valve one. The other branch line is connected to the first inlet of the second stage jet jet and is equipped with valve two. The second inlet of the first stage jet jet is connected to water tank one. The outlet of the first stage jet jet is connected to the second inlet of the second stage jet jet. The outlet of the second stage jet jet is connected to water tank two. The bottom of water tank two is connected to the circulation pool through a water supply line.

[0006] Compared with the prior art, the present invention has the following beneficial effects: This invention effectively solves the drawbacks of traditional condensation drainage methods, such as high humidity, high noise, and high energy consumption at the equipment site. It has the advantages of simple structure, water saving, energy saving, and convenient operation. Attached Figure Description

[0007] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0008] Figure 1 This is a schematic diagram of the overall structure of this utility model. Detailed Implementation

[0009] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0010] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, if the word "and / or" appears throughout the text, it means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0011] refer to Figure 1This utility model provides an air compressor condensate recovery device, including three coolers, a primary ejector, a secondary ejector, a water tank 1, a water tank 2, and a circulation pool, all arranged between the three compression sections of the air compressor. Each cooler has a condensate drain line at its bottom, with a drain valve located near the cooler on each drain line. Each drain line downstream of the drain valve has a float-type drain valve positioned horizontally upwards (to avoid air resistance) as an alarm valve, and its end enters water tank 1. The drain lines before the float-type drain valves of the primary and secondary coolers have downward branches, each branch equipped with a float-type drain valve as a working valve, and its end enters water tank 1. First, the drain line before the float-type steam trap of the final stage cooler has a branch on its side, and a check valve and valve three are installed in sequence on the branch. The check valve and valve three are installed at a height slightly lower than the steam trap 1 (to avoid air lock). The drain line after valve three is divided into two branches. One branch connects to the first inlet of the first stage jet jet and is equipped with valve one. The other branch connects to the first inlet of the second stage jet jet and is equipped with valve two. The second inlet of the first stage jet jet is connected to water tank 1. The outlet of the first stage jet jet is connected to the second inlet of the second stage jet jet. The outlet of the second stage jet jet is connected to water tank 2. The bottom of water tank 2 is connected to the circulation pool through a water supply line.

[0012] The working principle of this utility model is as follows: 1. Before starting the air compressor, check that the drain valves at the bottom of each cooler are in the open position; 2. When the air compressor starts, water-containing gas is discharged from the drain valve; 3. Close the drain valves one by one, and observe that the drain valve 5 of the primary cooler and the drain valve 3 of the secondary cooler should start working; 4. Fully open valve three of the final stage cooler and adjusting valve one to continuously spray water-containing air from the outlet of the second stage ejector; 5. Under the action of Venturi force, there should be negative pressure at the condensate outlet of a certain point in the water tank; 6. Once the liquid level in water tank one has exceeded its condensate outlet, the water will be carried into water tank two under negative pressure. 7. The water in tank two will flow into the circulation pool under the action of gravity; 8. If the negative pressure generated by the primary ejector is insufficient to draw water from tank one into tank two, the suction force can be increased by adjusting valve one and valve two to achieve a series arrangement of ejectors. 9. If steam traps 1, 2, and 4 start working, it indicates that steam traps 3 and 5 are faulty and should be checked or replaced.

[0013] The present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
