Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1 to 4 A multi-source desuperheating water switching device for a waste incineration deacidification tower includes a temperature water switching component 1, a deacidification tower 2 detachably connected to the middle of one side of the temperature water switching component 1, and a filter component 3 detachably connected between the temperature water switching component 1 and the deacidification tower 2.

[0017] The warm water switching assembly 1 includes a No. 1 backup water tank 11, a No. 2 backup water tank 12, and a No. 3 backup water tank 13. Each of these tanks is bolted and sealed with a tank connection valve 17 to a No. 1 water supply line 14, a No. 2 water supply line 15, and a No. 3 water supply line 16. There are three sets of tank connection valves 17. Flow meters 18, switching valves 19, and regulating valves 110 are bolted and sealed to the middle of each of the No. 1 water supply line 14, No. 2 water supply line 15, and No. 3 water supply line 16. There are six sets of flow meters 18 and six sets of switching valves 19, and three sets of regulating valves 110. A connecting pipe 111 is bolted and sealed to one end of the No. 1 water supply line 14. During operation, water from the backup water tanks enters the corresponding water supply lines through tank connection valves 17: water from backup water tank 11 flows into carbon steel water supply line 14 via tank connection valve 17; water from backup water tank 12 flows into PVC water supply line 15 via tank connection valve 17; and water from backup water tank 13 flows into stainless steel water supply line 16 via tank connection valve 17. During water supply, regulating valves 110 in the middle of each water supply line adjust the injected liquid flow rate according to the temperature requirements of the deacidification tower 2; flow meters 18 with remote transmission transmit the flow information of each branch to the local control cabinet and then to the DCS, facilitating real-time monitoring and adjustment by the central control unit; pressure gauges in each drain line provide data support for on-site maintenance; and six sets of switching valves 19 enable flexible switching between different water sources, ensuring the stability of multi-source backup.

[0018] The filter assembly 3 includes an inlet pipe 31, one end of which is welded to a U-shaped inlet pipe 32. The rear end of the U-shaped inlet pipe 32 is sealed to a first filter chamber 34 and a second filter chamber 35 via an inlet valve 33. The second filter chamber 35 is located behind the first filter chamber 34. Both the first filter chamber 34 and the second filter chamber 35 are sealed to an outlet valve 38. One end of the outlet valve 38 is detachably connected to a U-shaped outlet pipe 39. Before entering the water supply line, the water stored in each tank is treated by the filter assembly 3. The water first enters the inlet pipe 31 and is then diverted through the U-shaped inlet pipe 32 to the first filter chamber 34 and the second filter chamber 35, where precise filtration is completed by the filter elements 36 within the two filter chambers. The dual-path design of the dual filter chambers allows for non-stop maintenance by switching between them—when one filter chamber needs maintenance, simply close the inlet valve 33 and the outlet valve 38 of the corresponding path, and the other filter chamber can continue to operate. The filtered water enters the U-shaped outlet pipe 39 through the outlet valve 38 in the middle of the No. 1 filter chamber 34, and is finally transported to the deacidification tower 2.

[0019] Specifically, when multiple deacidification towers need to be supplied with desuperheating water, a corresponding number of stainless steel pipes and PE pipes can be added. These new pipes can be connected in series to the temperature water switching component 1 through the connecting pipe 111, thereby expanding the water supply path and ensuring that multiple deacidification towers can obtain a stable supply of desuperheating water to meet the needs of multi-equipment collaborative operation.

[0020] Specifically, the inner walls of filter chamber 34 and filter chamber 35 are detachably connected to the outer wall of filter element 36. The upper ends of filter chamber 34 and filter chamber 35 are sealed with sealing caps 37, which can be opened to maintain the filter element 36 inside filter chamber 34 and filter chamber 35.

[0021] Specifically, one end of water transmission line 14, water transmission line 15, and water transmission line 16 are all bolted and sealed to the connecting pipe 111. Water transmission line 14, water transmission line 15, and water transmission line 16 can finally be transported to the deacidification tower 2 through the connecting pipe 111.

[0022] Specifically, the No. 1 backup water tank 11 is made of carbon steel and can store industrial water. The No. 2 backup water tank 12 and the No. 3 backup water tank 13 are made of carbon steel with plastic linings. The No. 2 backup water tank 12 can store reclaimed water, and the No. 3 backup water tank 13 can store leachate station production water. The No. 1 backup water tank 11 is made of carbon steel and is used to store industrial water. The No. 2 backup water tank 12 and the No. 3 backup water tank 13 are made of carbon steel with plastic linings and store reclaimed water and leachate station production water respectively, which can adapt to water sources with different working fluid characteristics. Specifically, the material of water transmission line 14 is carbon steel, the material of water transmission line 15 is PVC, and the material of water transmission line 16 is stainless steel. The carbon steel used for water transmission line 1 is high in strength and low in cost, and is suitable for conventional water transmission; the PVC used for line 2 is corrosion resistant, lightweight and inexpensive, and is suitable for transporting media containing slight corrosive substances; the stainless steel used for line 3 is highly corrosion resistant and has high cleanliness, and is suitable for scenarios with high requirements for water quality and durability.

[0023] Specifically, water supply lines 14, 15, and 16 can be detachably connected to the middle of the filter assembly 3 via connecting pipe 111. The water supplied inside water supply lines 14, 15, and 16 must be filtered from the middle of the filter assembly 3 before being discharged.

[0024] Working Principle: When the equipment is working, the water in the No. 1 backup water tank 11, No. 2 backup water tank 12, and No. 3 backup water tank 13 enters the corresponding materials of the No. 1 water supply line 14 (carbon steel), No. 2 water supply line 15 (PVC), and No. 3 water supply line 16 (stainless steel) through the tank connection valve 17. Upon entering the water supply line, the water passes through the filter assembly 3 on the line. The water flows through the inlet pipe 31 and the U-shaped inlet pipe 32 and is divided into the No. 1 filter chamber 34 and the No. 2 filter chamber 35. After being filtered by the filter element 36, the water is delivered to the deacidification tower 2 through the outlet valve 38 and the U-shaped outlet pipe 39. The dual filter chambers can be maintained without stopping the machine by switching the inlet valve 33 and the outlet valve 38. After being filtered by the filter assembly 3, the water passes through the flow meter 18, the switching valve 19, and the regulating valve 110 on the line. After regulation, the regulating valve 110 in the middle of each water supply line adjusts the flow rate of the injected liquid according to the temperature requirements of the deacidification tower 2; the flow meter 18 with remote transmission transmits the flow information of each branch to the local control cabinet and sends it to the DCS, so that the central control can monitor and adjust in real time; the liquid pressure gauge of each drainage pipeline provides data support for on-site maintenance; the six sets of switching valves 19 realize flexible switching of different water sources, ensuring the stability of multi-source backup, and finally delivers water to the deacidification tower 2. If it is necessary to supply water to multiple deacidification towers, additional pipelines can be added in series through the connecting pipe 111 to expand the passage. The multi-source backup water tank is adapted to different water qualities with water supply lines of different materials, improving the flexibility of water supply. The dual-path filtration component ensures the filtration effect while achieving non-stop maintenance, reducing system downtime. The overall design takes into account both precise regulation and expansion capabilities, can stably meet the operating requirements of the deacidification tower, improve the stability and emergency handling capabilities of the deacidification system, and reduce the overall cost of equipment through material adaptation.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
