BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural diagram of the gas source optimization system in the embodiment of the present utility model. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] like Figure 1As shown, in this embodiment, a boiler dust collector air source optimization system is provided, comprising an air separation unit, a boiler dust collector, and three boiler air compressor units; the boiler air compressor unit comprises an air compressor and an air storage tank, the air outlet of the air compressor is connected to the air inlet of the air storage tank via an air inlet pipeline, the air inlet pipeline being provided with an air inlet check valve, the air outlet of the air storage tank is connected to the air inlet of the boiler dust collector via an air outlet pipeline, the air outlet of the air storage tank being provided with an air outlet check valve; the three boiler air compressor units are arranged sequentially in a direction close to the boiler dust collector, the air separation unit is connected to the air inlet of the air storage tank of the third boiler air compressor via a compressed air pipeline, and the compressed air pipeline is provided with a front check valve and a rear check valve at intervals. By drawing compressed air from the air separation unit to replace the air source of the air compressor unit, the quality of the compressed air used by the boiler dust collector is effectively improved.

[0019] In this embodiment, the gas tank is equipped with an on-site pressure gauge that can visually reflect the pressure of the gas tank in real time. The boiler air compressor device also includes a dryer, which is located between the gas tank and the outlet check valve. The dryer is used to dehumidify the gas discharged from the gas tank to facilitate the gas's entry into the boiler dust collector for dust removal.

[0020] In this embodiment, two exhaust lines are connected to the compressed air pipeline in sequence, and an exhaust check valve is provided on the pressure-dividing pipeline. The exhaust line is used to evacuate the compressed air from the pipeline. If the air separation gas source fails, the front and rear check valves on the compressed air pipeline can be closed, and the exhaust check valve can be opened to discharge the gas source in the pipeline, preventing the gas from entering the gas storage tank and affecting the normal operation of the subsequent boiler dust collector.

[0021] In this embodiment, the outlet of the air separation unit is connected to a main air pipeline, which is provided with a main check valve. A branch air pipeline is connected to the main air pipeline, with its ends connected upstream and downstream of the main check valve, respectively. A front branch air check valve, a pneumatic valve, and a rear branch air check valve are sequentially provided on the branch air pipeline. The compressed air pipeline is connected between the pneumatic valve and the rear branch air check valve. The air separation unit is an air separation steam turbine.

[0022] In this embodiment, there are three boiler dust collectors, the outlet pipes of the three boiler air compressor devices are all connected to the collecting pipe, and the air inlet end of each boiler dust collector is connected to the collecting pipe.

[0023] In this embodiment, before the air source is added to the system, the front air separation check valve and the front check valve are open, and the exhaust check valves on the two exhaust lines are closed. Before the air separation gas source is put into use, the first and second air compressors are started, and the third air compressor is shut down. The inlet check valve is opened, and the outlet check valve is closed.

[0024] When the air separation gas source is added to the system, slowly open the rear check valve and observe the local pressure gauge on the gas storage tank of the third boiler air compressor unit. When the pressure exceeds 0.6MPa, slowly open the outlet check valve and observe the pressure of the gas storage tank of the third boiler air compressor unit. The pressure should not be less than 0.5MPa. Continue until all the outlet check valves are fully opened. Otherwise, do not open the outlet check valves. After the boiler air compressor unit enters standby mode, the three air compressors serve as backup.

[0025] The compressed air pipeline leads the compressed air of the air separation unit to the air storage tank of the boiler air compressor unit, replacing the air compressor. The running air compressor is on standby. Set the air compressor starting pressure and install a check valve on the pipeline. When the air separation gas source fails, the air compressor can be started to ensure the air supply of the dust collector. The diameter of the compressed air pipeline is DN100, the pressure is 0.7Mpa, and the flow rate is 2280-3470Nm 3 / h, the boiler dust collector uses a flow rate of about 1000Nm 3 / h, the newly added compressed air pipeline can fully meet the use of the boiler dust collector, the newly added air source can meet the use of the boiler dust collector, and the boiler air compressor serves as a backup to ensure the stability of the compressed air of the boiler dust collector.

[0026] The air source optimization system effectively improves the quality of compressed air for boiler dust collectors and ensures stable valve operation. Compared to the existing system, one air compressor can be shut down, saving significant electricity costs. Compressor repair and maintenance are reduced compared to the existing system, resulting in significant savings in regular equipment maintenance and compressor oil. The system draws air from air separation units in other projects, reducing energy consumption and increasing efficiency.

[0027] By adopting the above technical solution disclosed in the utility model, the following beneficial effects are obtained:

[0028] The utility model provides a boiler dust collector air source optimization system. By setting a compressed air pipeline and corresponding valves, the compressed air of the air separation unit is led to the air compressor. The compressed air pipeline can meet the use of the boiler dust collector. The newly added air source meets the use of the boiler dust collector, and the air compressor serves as a backup, thereby ensuring the stability of the compressed air of the boiler dust collector, and solving the current problems of poor quality and instability of compressed air.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be considered within the scope of protection of the present invention.
