[0002] A coke oven is a device used in the coking process. It is used to pyrolyze solid fuels such as coal under high temperature conditions to volatilize the volatile substances in them to obtain coke. Wet flue gas desulfurization is a commonly used flue gas desulfurization method. The regeneration filter press is a device used in the wet desulfurization process of coke oven flue gas. It converts the sulfide in the flue gas into water-soluble sulfate by reacting the sulfide with the oxidant in the filtrate. The filtrate is then separated from the solid by pressure difference for reuse.

[0003] However, in actual use, the return pipe of the regeneration filter press is frequently blocked, causing overflow and affecting the regeneration operation. In severe cases, it may be necessary to cut the pipe and clean it manually. The pH value of the filtrate is 13.5, which is highly alkaline. The high pH value of the filtrate is highly corrosive to the skin, posing a major safety hazard.

[0004] Therefore, a pipeline flushing device is proposed. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] Embodiment 1, as Figure 1 As shown, a pipeline flushing device includes a regeneration filter press 1. The regeneration filter press 1 is a device for sulfide conversion and filtrate separation during the flue gas wet desulfurization process. The regeneration filter press 1 is provided with a reflux pipe 2, which is connected to a circulation pool 3. The circulation pool 3 stores and supplies circulating liquid to maintain the stable operation of the regeneration filter press 1. The reflux pipe 2 returns the circulating liquid to the circulation pool 3 to achieve the recycling of the circulating liquid and improve the resource utilization efficiency.

[0020] The return pipe 2 is connected to the flushing pipe 5 through the connecting branch pipe 4. The flushing pipe 5 cleans the return pipe 2 through the flushing operation to prevent blockage and ensure the normal operation of the system. The connecting branch pipe 4 connects the return pipe 2 and the flushing pipe 5. The flushing pipe 5 is connected to the wet electrostatic precipitator 6. The wet electrostatic precipitator 6 performs a wet electrostatic precipitator operation to remove solid particles and pollutants to ensure the cleanliness of the emission environment.

[0021] A water pump 9 is provided on the flushing pipeline 5. The water pump 9 is connected to an external water source to provide flushing fluid pressure, which is passed into the return pipeline 2 to achieve high-pressure flushing and keep the pipeline unobstructed.

[0022] The following is a detailed description of the design of the above key components:

[0023] The connecting branch pipes 4 are arranged in a certain number and arranged horizontally at the bottom of the head end of the return pipe 2 and connected to the top of the end of the flushing pipe 5. To ensure that the flushing pipe 5 can fully flush the return pipe 2, the number of connecting branch pipes 4 should be set according to actual needs, arranged horizontally at the bottom of the head end of the return pipe 2, and connected to the top of the end of the flushing pipe 5 to achieve uniform backwashing.

[0024] The flushing pipeline 5 is provided with a first valve 7 and a second valve 8, which are respectively installed on the flushing pipeline 5 to control the opening and closing of the flushing pipeline 5. By controlling the states of the two valves, the flushing operation of the reflux pipeline 2 can be controlled.

[0025] The circulation pool 3 is a desulfurization liquid circulation pool 3, which is used to store and circulate the desulfurization regeneration liquid. After the desulfurization liquid passes through the regeneration filter press 1, it flows back to the circulation pool 3 for subsequent recycling.

[0026] The first valve 7 and the second valve 8 are respectively arranged on both sides of the front and rear of the water pump 9 on the flushing pipeline 5. In order to better control the flow rate and pressure of the flushing fluid in the flushing pipeline 5, the first valve 7 should be arranged before the water pump 9, and the second valve 8 should be arranged after the water pump 9. By adjusting the switch state of the two valves, the return pipeline 2 is flushed and discharged through the wet electrostatic precipitator 6, and the supply and stop of the flushing fluid are controlled to meet different flushing requirements.

[0027] The contents not described in detail in this specification belong to the prior art known to professionals in this field.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
