Description

Technical Field

[0001] This utility model belongs to the field of desulfurization tower cleaning technology, and more specifically, relates to a desulfurization tower compressed air pipeline network. Background Technology

[0002] Coking is a traditional industry with a long history, playing an indispensable role in metal smelting. Coking involves heating coking coal in the absence of air to produce coke and raw coal gas. Coke provides energy and a reducing agent for metal smelting. Raw coal gas undergoes a series of treatments, including cooling and impurity removal, to provide residential gas and for special purposes such as LNG production.

[0003] The desulfurization tower employs a three-stage desulfurization process. Each tower is constructed in three sections. Coal gas enters the tower from the bottom, while the desulfurization liquid enters from the top. Both enter through three sections of packing material within the tower. The desulfurization liquid removes elemental sulfur from the coal gas and flows under its own pressure into the reaction tank from the bottom of the tower. After passing through the drain holes of each distributor channel, the desulfurization liquid contacts the coal gas more evenly and thoroughly, resulting in high desulfurization efficiency. Simultaneously, it adsorbs trace amounts of tar that were not removed after electrostatic precipitator treatment of the raw coal gas, providing production support for subsequent processes and playing a decisive role in ensuring that the flue gas treatment meets standards.

[0004] The desulfurization tower distributor's guide channel has many advantages, but the guide holes are prone to clogging, and poor drainage can accelerate packing blockage, resulting in high system resistance and difficulty in cleaning—a major challenge in the desulfurization and decyanation industry today. The traditional method for cleaning the distributor's guide channel involves manual disassembly and cleaning. This involves manually removing the bottom packing support plate and creating cleaning tools tailored to the width of the guide channel. Finally, the debris is manually removed piece by piece from the guide channel. This manual disassembly and cleaning method is time-consuming, and because the guide channel is located in the central area, the disassembly and movement of each component is cumbersome, making cleaning difficult and impacting production progress. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a desulfurization tower compressed air pipeline network, which solves the problem that the existing system, due to the central location of the guide channel, involves cumbersome disassembly and movement of various components, making cleaning difficult and affecting production progress.

[0006] To achieve the above objectives, this utility model provides a desulfurization tower compressed air pipeline network, comprising:

[0007] The main road is provided with branch roads that connect to each desulfurization tower;

[0008] A first valve, an automatic regulating valve, and a second valve are sequentially arranged on the main road;

[0009] A bypass, the two ends of which are connected close to the input end of the first valve and the output end of the second valve, respectively;

[0010] A cleaning valve, one end of which is connected to the main road, with the connection point located between the automatic regulating valve and the second valve, and the other end of which is connected to an air source;

[0011] The wind pressure alarm module is equipped with a conventional threshold and a cleaning threshold.

[0012] Optionally, the conventional threshold is 0.4-0.5 MPa, and the cleaning threshold is 0.6-0.7 MPa.

[0013] Optionally, a branch valve is provided on the branch.

[0014] Optionally, the cleaning valve is connected to the main line via a check valve.

[0015] Optionally, the inlet of the cleaning valve is provided with a pagoda-shaped nozzle.

[0021] This utility model provides a desulfurization tower compressed air pipeline network, the advantages of which are:

[0022] The desulfurization tower's compressed air pipeline is connected to an air source via a purge valve to increase the air pressure in the pipeline. High-pressure air is used to purge and clean the distributor's guide channels. Simultaneously, during the purging time, the air pressure alarm module switches from its normal threshold alarm to a purging threshold alarm. This solution is convenient to implement and simple to operate, allowing dirt to be blown to the drain for unified treatment without the need for laborious equipment disassembly, thus improving cleaning efficiency.

[0023] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0028] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0029] like Figure 1 As shown, a desulfurization tower compressed air pipeline network includes:

[0030] Main road, with branch roads 2 connected to each desulfurization tower on main road 1;

[0031] First valve 3, automatic regulating valve 4, and second valve 5 are sequentially installed on main line 1;

[0032] Bypass 6, with its two ends connected to the input end of the first valve 3 and the output end of the second valve 5, respectively.

[0033] The cleaning valve 7 has one end connected to the main line 1, with the connection point located between the automatic regulating valve 4 and the second valve 5. The other end of the cleaning valve 7 is connected to an air source.

[0034] The wind pressure alarm module has a set of normal threshold and cleaning threshold.

[0035] Specifically, by connecting the air source through the cleaning valve 7, the air pressure of the compressed air network is increased. The high-pressure air is used to blow clean the guide channel of the distributor. At the same time, during the blowing time, the normal threshold alarm of the air pressure alarm module switches to the cleaning threshold alarm. This solution is convenient to implement and simple to operate. It can blow dirt to the drain hole for unified treatment without the need for laborious disassembly of equipment, thus improving cleaning efficiency.

[0036] Specifically, the air source is a portable air compressor, which is convenient to move and store.

[0037] In this embodiment, the conventional threshold is 0.4-0.5 MPa, and the cleaning threshold is 0.6-0.7 MPa.

[0038] Specifically, a reasonable threshold range should be set to ensure the purging effect without damaging the equipment or affecting production.

[0039] In this embodiment, a branch 2 valve is provided on branch 2.

[0040] Specifically, the connection and disconnection between each desulfurization tower and the compressed air pipeline is controlled by branch valve 2.

[0041] In this embodiment, the cleaning valve 7 is connected to the main line 1 via a check valve.

[0042] Specifically, avoid reverse backflow of air sources in the compressed air pipeline network.

[0043] In this embodiment, the input end of the cleaning valve 7 is provided with a pagoda nozzle.

[0044] Specifically, the pagoda nozzle allows for easy connection of the air source and the cleaning valve 7 via a flexible hose.

[0045] In this embodiment, a dust cover is detachably connected to the pagoda-shaped mouth.

[0046] Specifically, a dust cover is used to prevent daily dust and impurities from clogging and contaminating the pagoda-shaped nozzle.

[0047] In this embodiment, a bypass on / off valve is provided on the bypass 6.

[0048] Specifically, the opening and closing of bypass 6 is controlled by the bypass on / off valve.

[0049] In this embodiment, the main road 1 is equipped with a first pressure relief valve.

[0050] In this embodiment, the bypass 6 is equipped with a second pressure relief valve.

[0051] In this embodiment, the air source is an air compressor.

[0052] This embodiment uses the cleaning of the distributor guide channel as an example when using a desulfurization tower air compressor pipeline network:

[0053] When the desulfurization tower needs to be cleaned and the distributor guide channel needs to be cleaned, first switch the normal threshold alarm of the wind pressure alarm module (0.4MPa) to the cleaning threshold alarm (0.6MPa), and then connect the cleaning valve 7 to the air source to clean the distributor guide channel.

[0054] If multiple desulfurization towers are connected to the compressed air pipeline, they can be cleaned sequentially. During cleaning, adjust valve 2 of branch line to ensure the normal air pressure of the desulfurization towers that are not being cleaned, without affecting normal production.

[0055] This solution is easy to implement for improving existing desulfurization towers, has low cost, effectively reduces maintenance cycles, and improves production efficiency.

[0056] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
