Description

Technical Field

[0001] The utility model relates to the technical field of acid regeneration, in particular to a combined air-supplementing compressed air pipe network. Background Art

[0002] Some processes in the acid regeneration process require compressed air. Compressed air is usually transported to the compressed air network by a separate air compressor station, and then transported to each required equipment by the compressed air network. The air compressor station is composed of multiple air compressor units. When a unit needs to be shut down for maintenance or a fault trips due to abnormal data, in order to ensure the normal gas use of the back-end production line, operators are required to go to the site to manually open and close valves and use the company's pipeline compressed air for pressure replenishment and joint gas supply. This operation not only increases the workload of the operators, but also has low work efficiency. If the pressure is not replenished in time, it is easy to cause the acid regeneration unit to trip due to low compressed air pressure, and it needs alkaline washing to resume normal production, affecting the acid regeneration treatment of waste acid and the preparation of new acid. The compressed air transported by the air compressor station usually has tiny solid particles, water droplets, oil droplets and other impurities inside. These impurities will gradually corrode and damage the equipment as the compressed air is transported to the inside of the equipment. Therefore, a filtering part needs to be added to the compressed air network. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a combined air-supplementing compressed air pipeline network in view of the above shortcomings.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A combined air-supplementing compressed air network comprises a compressed air network, an air supply pipe of an air compressor station, a check valve, an automatic air-supplementing valve and a pressure-supplementing air supply pipe, wherein one input end of the compressed air network is connected to the output end of the air supply pipe of the air compressor station, and the other input end of the compressed air network is also connected to the pressure-supplementing air supply pipe, and the input end of the pressure-supplementing air supply pipe is connected to an external air supply station; a check valve and an automatic air-supplementing valve are sequentially arranged between the external air supply station and the input end of the pressure-supplementing air supply pipe, and a plurality of sub-pipelines are branched out from the end of the main pipeline of the compressed air network, and a pressure relief valve is arranged at the output end of each sub-pipeline.

[0006] Furthermore, a filter assembly is provided on the main pipeline of the compressed air network, and the filter assembly includes a shell, a partition, an impurity filter element and an oil suction filter element. A partition is vertically provided on the inner side of the shell, and a through hole is provided on the partition. The partition divides the shell into a filter chamber on the left and an oil suction chamber on the right. An impurity filter element is provided on the inner side of the filter chamber, and an oil suction filter element is provided on the inner side of the oil suction chamber.

[0007] Furthermore, the impurity filter element is made of sponge material.

[0008] Furthermore, the oil absorption filter element is made of polyurethane foam.

[0009] Furthermore, a gas-water separator is provided on the main pipeline of the compressed air network at the rear end of the filter assembly, and the gas-water separator is used to separate the moisture in the main pipeline of the compressed air network and continue to transport the gas to the rear end sub-pipeline.

[0010] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0011] The utility model provides a pressure-boosting pipeline, a check valve and an automatic air-boosting valve. When a problem occurs in the air compressor unit of the air compressor station, causing the air pressure output by the air transmission pipe of the air compressor station to drop to a limited value, the automatic air-boosting valve opens to allow the compressed air in the pressure-boosting air transmission pipe to enter the compressed air network, thereby increasing the air pressure in the compressed air network. If the automatic air-boosting valve is damaged and fails, the check valve can serve as a backup pressure-boosting valve. When the pressure in the air transmission pipe of the air compressor station is greater than the pressure in the pressure-boosting air transmission pipe, the compressed air output by the air transmission pipe of the air compressor station can be prevented from flowing back into the pressure-boosting air transmission pipe. A pressure relief valve is provided at the output end of the compressed air network to prevent the pressure at the output end of the compressed air network from being greater than the working pressure of the equipment, thereby ensuring the normal supply of compressed air, improving the production quality and efficiency of the air compressor station and acid regeneration, and reducing the labor intensity of workers. By providing a filter component and an air-water separator, solid particles, water droplets, oil droplets and other impurities in the compressed air can be filtered out to avoid damage to external equipment.

[0020] like Figure 1-3 As shown, a combined air-supplementing compressed air network comprises a compressed air network 1, an air compression station air pipeline 2, a check valve 3, an automatic air-supplementing valve 4 and a pressure-supplementing air pipeline 5, wherein one input end of the compressed air network 1 is connected to the output end of the air compression station air pipeline 2, and the other input end of the compressed air network 1 is also connected to the pressure-supplementing air pipeline 5, and the input end of the pressure-supplementing air pipeline 5 is connected to an external air transmission station; a check valve 3 and an automatic air-supplementing valve 4 are sequentially arranged between the external air transmission station and the input end of the pressure-supplementing air pipeline 5, and a plurality of sub-pipelines are branched out from the end of the main pipeline of the compressed air network 1, and a pressure relief valve 6 is arranged at the output end of each sub-pipeline.

[0021] As an embodiment, a filter assembly 7 is provided on the main pipeline of the compressed air network 1, and the filter assembly 7 includes a shell 701, a partition 702, an impurity filter element 703 and an oil suction filter element 704. A partition 702 is vertically provided on the inner side of the shell 701, and a through hole is provided on the partition 702. The partition 702 divides the shell 701 into a filter chamber on the left and an oil suction chamber on the right. An impurity filter element 703 is provided on the inner side of the filter chamber, and an oil suction filter element 704 is provided on the inner side of the oil suction chamber.

[0022] As an implementation method, the impurity filter element 703 is made of sponge material.

[0023] As an implementation method, the oil absorption filter element 704 is made of polyurethane foam.

[0024] As an embodiment, a gas-water separator 8 is provided on the main pipeline of the compressed air network 1 at the rear end of the filter assembly 7, and the gas-water separator 8 is used to separate the moisture in the main pipeline of the compressed air network 1 and continue to transport the gas to the rear end sub-pipeline.

[0025] In the present utility model, the model of the automatic air supply valve 4 is BQZB-15-220VDC, the model of the check valve 3 is KA-L15, and the model of the gas-water separator 8 is Matt DN80 gas-water separator.

[0026] The working process of the utility model is as follows: the opening and closing conditions of the automatic air supply valve 4 are set as follows: when the compressed air outlet pressure of the air supply pipe 2 of the air compressor station is lower than a preset opening threshold, the automatic air supply valve 4 is opened, and the opening threshold of this embodiment adopts 0.48MPa, and the pressure supply pipe 5 and the air supply pipe 2 of the air compressor station jointly supply air; when the compressed air outlet pressure of the air supply pipe 2 of the air compressor station reaches a preset closing threshold, the closing threshold of this embodiment adopts 0.52MPa, the automatic air supply valve 4 is closed, and only the air supply pipe 2 of the air compressor station supplies air; when the automatic air supply valve 4 loses its function, the check valve 3 at its front end can play an automatic pressure supply role when the outlet pressure of the air compressor station is lower than the company's pipeline pressure; the pressure of the check valve 3 The force value is set to 0.52MPa. When the outlet pressure of the air compressor station is greater than the company's pipeline pressure, the check valve 3 can prevent the air compressor station's gas from flowing back into the company's gas pipeline, causing energy loss and affecting the gas pressure of the back-end production line. When the pressure at the output end of the compressed air network 1 is greater than the operating pressure of the equipment, the pressure relief valve 6 opens to relieve pressure; after the compressed air enters the main pipeline of the compressed air network 1, it first passes through the filter assembly 7, and inside the filter assembly 7, it first passes through the impurity filter element 703 and then the oil suction filter element 704, and then passes through the gas-water separator 8 to ensure that the compressed air delivered to the output end is clean and avoid damage to external equipment. The impurity filter element 703 and the oil suction filter element 704 need to be replaced after a period of use.
