[0023] In a preferred embodiment, first filter screen 6 is installed in the inside of siphon well 1, and slag discharge channel 7 is fixedly installed outside siphon well 1, and slag discharge channel 7 is communicated with the inside of siphon well 1, because there are many impurities in seawater, and there are also much silt, impurities will be extracted together when seawater is extracted, the device first gathers water in the inside of siphon well 1, and then continues to transport, first filter screen 6 is installed in the inside of siphon well 1, which can filter impurities, and isolate impurities in the inside of siphon well 1, as the water volume in the inside of siphon well 1 continuously increases, impurities will be discharged from the position of slag discharge channel 7, so as to discharge impurities from the inside of siphon well 1, avoid taking impurities into absorption tower, and further block absorption tower nozzle, affect desulfurization efficiency, and seriously forced to reduce load operation.

[0024] In a preferred embodiment, a three-way valve 8 is installed on the slag discharge pipe 43, and an expansion joint 9, a manual door 10 and an electric door 11 are sequentially installed outside the slag discharge pipe 43. The three-way valve 8 is installed on the slag discharge pipe 43 to facilitate the connection of the slag discharge pipe 43, and a long enough slag discharge pipe 43 can be connected according to the actual use length. The manual door 10 and the electric door 11 are installed on the slag discharge pipe 43. During daily use, the electric door 11 is used for operation. Once the electric door 11 fails, the manual door 10 can be controlled for operation to ensure normal infusion and avoid affecting operation.

[0025] To improve work efficiency, two slag discharge pipes 43 are provided. One end of each of the two slag discharge pipes 43 penetrates the inside of the siphon well 1 and extends to the outside of the siphon well 1. The distance between the slag discharge pipe 43 installed inside the two return water pipes and the return water butterfly valve 41 is 1.4 m. The use of two slag discharge pipes 43 can increase the flow rate, improve the water delivery capacity, save time and improve work efficiency.

[0026] Specifically, the working process or working principle of the water filter sewage device is as follows: With the increasing attention to environmental protection, water is generally used in desulfurization operation in enterprise desulfurization operation. In the use of seawater in desulfurization operation, the seawater quality is relatively poor, and the content of silt is large. There are also a large amount of impurities and garbage in seawater, such as plastic ribbons, sand particles, marine organisms and shells. At present, these garbage cannot be blocked outside the water suction equipment by the grid. When water is pumped, these garbage will be sucked together, part of which will be sucked into the absorption tower by the suction pump, thereby blocking the nozzle of the absorption tower and affecting the desulfurization efficiency. In severe cases, forced load reduction operation is required, which affects use. Therefore, the device is designed to solve this problem.

[0027] Seawater is pumped by an external water pump through the first return water pipe 2 and the second return water pipe 3 to the inside of the siphon well 1. The water passes through the first filter screen 6 in the inside of the siphon well 1, is filtered by the first filter screen 6, and then is pumped by an external infusion pipe to the inside of the hollow bin 42 and passes through the position of the second filter screen 421, is filtered again by the second filter screen 421, and is treated. After the water is treated, it is pumped by an external water pump to the inside of an external absorption tower.

[0028] During continuous water delivery, a large amount of impurities will accumulate on one side of the second filter screen 421. To avoid the impurities being delivered together with the water to the outlet of the storage tower and causing blockage of the outlet, the second filter screen 421 needs to be backwashed regularly. The water in the hollow bin 42 is backwashed in the opposite direction to clean the impurities.

[0029] When the backwash operation is performed, the backwater butterfly valve 41 on the first backwater pipe 2 and the second backwater pipe 3 is in a closed state to prevent impurity-containing water from entering the inside of the first backwater pipe 2 and the second backwater pipe 3. In the backwash operation, water flows reversely from the inside of the hollow bin 42 to the inside of the discharge pipe 43. At this time, the outside liquid delivery pipe is in a closed state. The water in the backwash process washes away the impurities accumulated in the inside of the second filter screen 421 and flows in the discharge pipe 43 along with the water flow.

[0030] The device is used to prevent impurity-containing sewage from entering the siphon well 1. Therefore, in the design, one end of the two discharge pipes 43 penetrates the inside of the siphon well 1 and extends from the inside of the siphon well 1 to the position of the discharge channel 7. The discharge channel 7 on the siphon well 1 is used to discharge the impurities. Therefore, the one end of the discharge pipe 43 arranged in the discharge channel 7 can discharge the impurities and avoid entering the siphon well 1. At the same time, the sewage can also be prevented from entering the inside of the first backwater pipe 2 and the second backwater pipe 3. When the subsequent water is pumped, a large amount of impurities can be avoided from being delivered to the inside of the siphon well 1, thereby meeting the use.

[0031] The initial investment of the device is only 50% of the conventional scheme. At the same time, there is almost no maintenance cost in the later period. Only the periodic inspection and defect elimination are needed. The limited load event due to the blockage of the absorption tower nozzle does not occur.
