[0027] See Figure 1 and combined Figures 2-5 The multi-nozzle circulating water tank for exhaust gas treatment in this application includes a water tank body 1 that is higher in the front and lower in the back. The water tank body 1 is provided with front and rear vertical partitions 2 at the junction of the high and low parts inside, which are used to divide the interior of the water tank body 1 into front and rear spaces. The front and rear vertical partitions 2 are provided with filter components 3. The front of the water tank body 1 is provided with a reaction tower interface 11 and a washing tower interface 12. Multiple sets of nozzle assemblies 4 are provided in the front space of the water tank body 1 for spraying the exhaust gas introduced into the water tank body 1. The front space is provided with left and right vertical partitions 5 to divide the front space so that the left and right partitions correspond to the reaction tower interface 11 and the washing tower interface 12 respectively. The water tank body 1 is provided with viewing windows at the front and rear.

[0028] The water tank body 1 in this application has a front-high and rear-low layout. After the water tank is assembled, it includes the water tank body 1, viewing window, reaction tower interface 11, washing tower interface 12, circulating nozzle assembly 4, thermocouple assembly 7, vertical water pump 6, circulating water pipeline 9, water tank internal filter assembly 3, and liquid level sensor and other components.

[0029] The main body of the water tank 1 is made of stainless steel plate by bending and welding. The viewing window includes a viewing window plate 13 located at the front. A viewing window 14 is provided at the front of the main body of the water tank 1. A viewing window flange is welded to the viewing window 14. There is a caliper groove at the rear of the viewing window flange. A positioning pin is provided in the middle of the viewing window flange. The viewing window flange is welded to the main body of the water tank 1. Transparent PVC or acrylic plate is used as the viewing window plate 13. Positioning holes and caliper grooves are provided on the edge of the viewing window plate 13. Multiple calipers are used to fix the viewing window plate 13 to the viewing window 14 of the main body of the water tank 1.

[0030] The use of calipers to fix the viewing window plate 13 facilitates maintenance and disassembly. The caliper uses a through-type groove, which can be easily added to ensure sealing performance in the event of a leak. If the caliper gets stuck, it can be easily removed from the through-type groove. The viewing window plate 13 and the viewing window 14 are sealed together with an adhesive gasket. The use of a single-sided adhesive corrosion-resistant gasket facilitates assembly and disassembly, and the adhesive gasket will not fall off during disassembly and installation.

[0031] The lower front part of the main body 1 of the water tank is a water tank fixing plate, with a total of four plates. The front viewing window 13 also facilitates observation of the internal state of the water tank, and a rear viewing window is also provided at the rear to facilitate observation of the interior space at the rear.

[0032] The reaction tower interface 11 and the washing tower interface 12 are located on the front top plate of the water tank body 1, at the upper front part of the water tank body 1. Both interfaces are ISO clamp flanges for easy installation and disassembly, and are sealed with O-rings to the reaction tower and washing tower. The reaction tower interface 11 has evenly distributed support plates inside for reserving installation accessories. Several other KF flanges 17 are also provided on the front top plate of the upper front part of the body, which can also be used to install other accessories, forming reserved openings for the water tank body 1.

[0033] A vertical water pump 6 and a transparent viewing window are installed on the upper rear part of the main body 1 of the water tank. Both are located on the rear top plate. The rear top plate is provided with a water pump connection port and a viewing window connection port. The vertical water pump 6 is connected to the water tank flange plate 16. The water tank flange plate 16 is fixedly connected to the water pump connection port by fasteners.

[0034] Specifically, the vertical water pump 6 is fixed to the water tank using screws and nuts. The screws are first screwed onto the water tank flange plate 16, and then the nut and washer are used to fix the water tank flange plate 16 to the water pump connection port. Compared with bolt fixing, this can reduce the gap between the water tank and the outside and enhance the sealing performance of the water tank.

[0035] The rear transparent window includes a transparent PVC or acrylic perforated plate 15. The perforated plate 15 is also fixedly connected to the window connection port by fasteners. The perforated plate 15 is screwed onto the window connection port by screws, and then the perforated plate 15 is fixed onto the window connection port by nuts and washers.

[0036] The positions of the vertical water pump 6 and the rear transparent window can be swapped as needed. The rear transparent window allows observation of the water level and water quality at the rear of the water tank. The window perforated plate 15 has multiple reserved holes for installing accessories.

[0037] A KF flange 17 for installing a float level sensor is provided between the vertical water pump 6 and the rear transparent window. The float level sensor is completely protected by a PVC protective pipe to prevent the disturbance of the liquid inside the water tank from affecting the function of the level sensor, and also to prevent impurities in the liquid from jamming the level sensor.

[0038] The PVC protective pipe has a vent hole 22 at the top, which allows the water tank to be connected to the inside of the protective pipe, preventing the liquid level sensor from being unable to accurately measure the liquid level in the water tank due to a liquid level difference.

[0039] The water tank body 1 has a reserved mounting position for a photoelectric liquid level sensor on the rear side plate, and a local liquid level gauge 18 is installed on the rear side plate. The water level of the water tank is introduced into the transparent tube using two through-plate connectors 24 and a transparent tube, and then multiple photoelectric sensors are installed to measure the liquid level.

[0040] Unlike photoelectric level sensors, float level sensors cannot adjust the water level. Therefore, photoelectric level sensors can be combined with control systems to control and adjust the operating conditions of the water pump to regulate the liquid level in the rear space.

[0041] The left and right vertical partitions 5 are set in the middle of the front space of the water tank body 1, which can separate the space from the upper front to the upper rear to the bottom of the water tank body 1.

[0042] The front space of the main body 1 of the water tank has a reaction tower interface 11 and a washing tower interface 12. The liquid inside contains a lot of impurities. The rear space of the water tank has a water pump and a liquid level sensor. Neither of them can operate in liquid with a lot of impurities. The front and rear vertical partitions 2 separate the front and rear spaces. The filter assembly 3 is installed at the bottom of the front and rear vertical partitions 2. The filter assembly 3 is assembled using PVC pressure plate 32 and filter screen 33.

[0043] Specifically, the filter assembly 3 includes a filter assembly body 31, a PVC pressure plate 32, and a filter screen 33. The filter assembly body 31 is provided with a groove, the filter screen 33 is installed in the groove, and the filter screen 33 is pressed and fixed by the PVC pressure plate 32. The PVC pressure plate 32 is pressed and fixed on the filter assembly body 31 by PVC screws 34.

[0044] The side of the filter assembly body 31, specifically the back of the filter assembly body 31, is provided with a sealing ring groove and a filter sealing ring, and the filter sealing ring is installed in the sealing ring groove.

[0045] The front and rear vertical partitions 2 include baffles located at the bottom of the water tank, and a welded fixing plate 21 is provided on the front and rear vertical partitions 2. The filter assembly body 31 is assembled and connected with the welded fixing plate 21.

[0046] The filter assembly 3 is easy to install and disassemble. During installation, the filter assembly 3 can be inserted into the baffle and then pressed down into the fixing plate, which makes it easy to disassemble and install the filter assembly 3.

[0047] During use, debris may adhere to the filter screen 33, affecting the operation of the water pump in the rear space of the water tank. The filter screen 33 will be cleaned regularly. Both the overall viewing window 13 at the front of the water tank and the filter screen 33 are easy to filter and clean. Debris inside the water tank can also be cleaned by quickly disassembling the overall viewing window 13 at the front of the water tank.

[0048] Ventilation holes 22 are provided in the middle of the front and rear vertical partitions 2 to allow the pressure in the front and rear spaces to communicate, preventing the pressure difference between the front and rear areas of the water tank from causing a difference in water level and affecting the normal operation of the water tank.

[0049] The upper part of the water tank body 1 is provided with multiple nozzle assemblies 4 and thermocouple assemblies 7. The nozzle assemblies 4 are also located in the front left and right spaces, and the thermocouple assemblies 7 are located in the lower part of the reaction tower interface 11.

[0050] The nozzle assembly 4 is fixed using a through plate 41 and supported by a cylindrical strip 42 that runs through the left and right partition spaces. The nozzle assembly 4 has a large number of nozzles and the components are of poor quality. Using the cylindrical strip 42 to support the assembly can reduce the pressure on the PVC pipe at the through plate 41.

[0051] The through plate 41 has a sealing ring inside, that is, a sealing ring is set at the junction of the nozzle assembly 4 and the through plate 41. Since the inside of the water tank is coated with Teflon for corrosion protection, the inside of the water tank should not have threads that affect the corrosion protection performance as much as possible. The sealing ring inside the opening of the through plate 41 can effectively seal the seal and facilitate the removal of the nozzle assembly 4 from the front viewing window 13 of the water tank.

[0052] The nozzle assembly 4 has a union 43 for connection to an external water pipe connector. When there are no issues with the assembly through-plate 41, the union 43 can be directly removed to take the nozzle out through the front viewing window of the water tank for maintenance. The threaded pressure plate on the through-plate 41 has evenly distributed small holes, facilitating the installation and removal of the through-plate 41 using custom tools.

[0053] Within the space of the upper front window panel 13 of the water tank, there are left and right vertical partitions 5 to separate the washing tower interface 12 from the reaction chamber interface. The lower part of the reaction tower interface 11 mainly has a nozzle assembly 4 and a thermocouple assembly 7.

[0054] Below the scrubbing tower interface 12 is a PVC drawer assembly 8, which is also supported by a cylindrical strip 42 base. The drawer assembly 8 includes an orifice plate 81 at the top to facilitate gas passage, and the space on the orifice plate 81 is used to install water dispersion packing.

[0055] Specifically, a Pall ring or other water-dispersing substance can be installed inside the drawer assembly 8, mainly to increase the contact area between the gas and water, so that the exhaust gas can be quickly dissolved in the water.

[0056] A drain pipe 23 is provided in the middle of the front and rear vertical partitions 2. The bottom of the drain pipe 23 extends to the bottom plate of the water tank in the front space. The drain pipe 23 is fixed to the upper part of the front and rear vertical partitions 2 through a through-plate connector 24. The through-plate connector 24 is used to connect a diaphragm valve or drain pipe 23 to discharge particulate impurities at the bottom of the front space.

[0057] The outlet of the vertical water pump 6 is connected to a circulating water pipe 9. A float flow meter 91 and a diversion pipe 92 are installed on the circulating water pipe 9. The float flow meter 91 has a flow switch that can detect the water flow and trigger an alarm. The diversion pipe 92 is used to divert the liquid output by the vertical water pump 6 to the nozzle assembly 4.

[0058] The multi-nozzle circulating water tank for exhaust gas treatment in this application facilitates observation of the water quality inside the tank body 1, and also facilitates maintenance of internal components.

[0059] The filter screen 33 can be quickly disassembled and installed, which facilitates dividing the inside of the water tank into a front sewage area and a rear clean water area. Multiple circulating water nozzle assemblies 4 are installed, and each assembly can be equipped with multiple nozzles. Multiple nozzles can effectively clean the dust in the exhaust gas and increase the contact area between the exhaust gas and water, ensuring the treatment effect of the exhaust gas.

[0060] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
