Description

Technical Field

[0001] This utility model relates to the field of flushing system technology, specifically a flushing system for a desulfurization absorption tower demister. Background Technology

[0002] The demister in the desulfurization absorption tower needs to be rinsed with flushing water, which is delivered to the flushing nozzles through a pipeline. Due to wear and tear on the equipment and pipelines and sedimentation caused by the internal structure of the water during the flushing process, some impurities are mixed in with the flushing water. The nozzles have a small diameter, and impurities can easily clog the nozzles during the flushing process, causing the demister to fail to be rinsed and thus leading to the shutdown of the desulfurization system. Utility Model Content

[0003] The main purpose of this utility model is to provide a demister flushing system for desulfurization absorption towers, so as to solve the problem that impurities easily clog the nozzles during the demister flushing process of desulfurization absorption towers in the prior art.

[0004] To achieve the above objectives, this utility model provides a desulfurization absorption tower demister flushing system, including a process water tank and an absorption tower. The absorption tower contains a demister and a flushing pipe for flushing the demister, with multiple flushing nozzles on the flushing pipe. The process water tank is connected to the flushing pipe via a delivery pipe. A filter device is connected to the delivery pipe. The filter device includes a filter box with an inlet and an outlet. A filter screen is installed at the outlet, and a brush for cleaning the filter screen is installed inside the filter box. A motor capable of driving the brush is installed on the filter box.

[0005] Furthermore, the filter box has a cylindrical inner cavity, and the motor output shaft is located inside the filter box. The motor output shaft is fixedly connected to the brush via a connecting bracket.

[0006] Furthermore, a drain outlet is provided at the bottom of the filter box, and a valve is installed on the drain outlet.

[0007] Furthermore, the bottom of the filter box is equipped with a drain trough, which is inclined at one end and lower at the other, with the drain outlet located at the lowest end of the drain trough.

[0008] This invention can filter the rinsing water entering the absorption tower by setting up a filtration device, and can brush and clean the filter screen of the filtration device by setting up a brush and a motor to prevent the filter screen from clogging. By setting up a drain outlet, the drain outlet can be opened periodically to discharge impurities. Attached Figure Description

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] like Figures 1 to 2 As shown in the embodiment of this utility model, a desulfurization absorption tower demister flushing system is provided, including a process water tank 1 and an absorption tower 2. The absorption tower 2 is equipped with a demister 201 and a flushing pipe 4 for flushing the demister 201. The flushing pipe 4 is equipped with multiple flushing nozzles 401. The process water tank 1 is connected to the flushing pipe 4 through a conveying pipe 5. A conveying pump 6 and a filter device 3 are connected to the conveying pipe 5. The filter device 3 includes a filter box 302, which is provided with an inlet 305 and an outlet 306. A filter screen 301 is provided at the outlet 306. A brush 303 for cleaning the filter screen 301 is provided inside the filter box 302. A motor 304 capable of driving the brush 303 to rotate is provided on the filter box 302.

[0016] The filter box 302 has a cylindrical inner cavity 307. The output shaft of the motor 304 is located inside the filter box 302. The output shaft of the motor 304 is fixedly connected to the brush 303 through a connecting bracket. During the process of conveying process water, the conveying pipe 5 keeps the motor 304 in the open state. The motor 304 drives the brush 303 to rotate, and the brush 303 can brush the filter screen 301 to avoid clogging the filter screen 301.
