Description

Technical Field

[0001] This invention relates to the field of measuring device technology, specifically to a salinity meter and pH meter measuring device for a wet desulfurization tower in a hazardous waste incineration flue gas treatment system. Background Technology

[0002] Wet acid removal is widely used in industries such as thermal power generation, cement, steel, and hazardous waste disposal.

[0003] Wet sulfuric acid removal systems typically employ two types of towers: internal circulation and external circulation. External circulation salinity meters and pH meters are generally installed on the circulating pool, while internal circulation meters are installed inside the desulfurization tower. When installed on the circulating pool, the liquid level fluctuates significantly when the flue gas flow and temperature are unstable. This can lead to damage to the instruments due to low liquid levels, or short circuits caused by the liquid level rapidly rising and submerging the instrument junction box. High-temperature circulating liquid in the pool can also cause water vapor to enter the junction box, resulting in short circuits. Therefore, strict requirements are placed on the length and installation orientation of the instruments. Furthermore, uneven liquid flow within the pool can lead to significant deviations in instrument measurement data, hindering the control of circulating liquid salinity and pH, resulting in low flue gas desulfurization efficiency and emissions exceeding standards. When salinity meters and pH meters are installed inside the deacidification tower, the problems are significantly improved compared to installing them above the water tank. However, since isolation valves cannot be used for the installation of salinity meters and pH meters, if the instruments malfunction and require maintenance, the pump must be stopped. Otherwise, it will cause the flue gas or circulating liquid to overflow, resulting in secondary pollution. In addition, the general drain outlets are manually adjustable switches. It would be more efficient if there were two different adjustment methods: remote and manual. The valves could be opened remotely at any time for draining. Moreover, the valves for the inlet and outlet of the circulating liquid may affect the operation due to the discharge volume being too large or too small, which is different from the expected discharge volume. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a salinity meter and pH meter measuring device for a wet desulfurization tower in a hazardous waste incineration flue gas treatment system. This device allows for maintenance without system shutdown, significantly improving system stability, operability, and economy. It also offers advantages such as effective control of inlet and outlet discharge rates and diversified functions for the drain valves. This solves the problems of having to stop the pump for maintenance when instruments malfunction, which could lead to flue gas or circulating liquid overflow and secondary pollution, as well as the limitations of single-function drain valves and inconvenient discharge rate control.

[0008] Preferably, the U-shaped housing assembly includes a U-shaped housing, with a circulating fluid high-level inlet valve connected to the top edge of the left side surface of the U-shaped housing, and a circulating fluid high-level outlet valve connected to the top edge of the right side surface of the U-shaped housing.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a salinity meter and pH meter measuring device for a wet desulfurization tower in a hazardous waste incineration flue gas treatment system, which has the following advantages:

[0018] 1. The salinity meter and pH meter measuring device in the wet desulfurization tower of the flue gas treatment system of this hazardous waste incineration unit provides real-time data to ensure that the salinity and pH in the desulfurization tower are within the design range, thereby guaranteeing desulfurization efficiency. This effectively avoids problems such as corrosion of the salinity meter and pH meter by the circulating liquid, short circuits due to water inlet, or short circuits caused by hot gas condensate during use. The salinity meter and pH meter are easy to maintain and replace, and will not cause the desulfurization system to shut down due to maintenance, ensuring stable and effective operation of the unit. The high-level inlet valve of the circulating liquid can control the flow rate of the circulating liquid into the system, meeting the requirements of system operation and maintenance. This solves the problem that if the instruments malfunction and maintenance is required, the pump must be stopped, otherwise it will lead to the overflow of flue gas or circulating liquid, causing secondary pollution.

[0019] 2. The salinity meter and pH meter measuring devices in the wet desulfurization tower of the hazardous waste incineration unit's flue gas treatment system can be conveniently installed in a U-shaped housing, making this system independent of the desulfurization system. Since the inlet and outlet of the circulating liquid in the U-shaped housing are both at high levels, a certain amount of liquid remains in the U-shaped housing after the wet desulfurization pump stops, which can soak the salinity meter and pH meter, preventing electrode bulb failure and instrument damage due to insufficient liquid. In addition, the high-level outlet valve of the circulating liquid ensures that the liquid level in the U-shaped housing remains constant after the desulfurization pump stops. The drain valve can periodically clean the salt deposited in the housing, ensuring the measurement accuracy of the salinity meter and pH meter. Furthermore, a remote controller can be installed at the drain valve to remotely control the valve opening and closing, enabling real-time remote draining. Pressure transmitters are installed at the inlet and outlet valves to adjust and control the discharge rate, preventing uneven discharge rate from affecting work efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Please see Figures 1-4A wet desulfurization tower salinity meter and pH meter measuring device includes a U-shaped housing assembly 1. A remotely controllable drain valve assembly 2 is connected to the center of the bottom surface of the U-shaped housing assembly 1. Pressure transmitter assemblies 3 are respectively connected to the top edges of the left and right sides of the U-shaped housing assembly 1. A salinity meter assembly 4 and a pH meter assembly 5 are respectively connected to the top edges of the U-shaped housing assembly 1. The U-shaped housing assembly 1 includes a U-shaped housing 101, and a circulating liquid is connected to the top edge of the left side of the U-shaped housing 101. A high-level inlet valve 102 is provided. A circulating fluid high-level outlet valve 105 is connected to the top edge of the right side surface of the U-shaped housing 101. A round hole connector A103 is connected to the left edge of the top surface of the U-shaped housing 101, and a round hole connector B106 is connected to the right edge of the top surface of the U-shaped housing 101. A rubber ring A104 is provided at the center of the top surface of the round hole connector A103, and a rubber ring B107 is provided at the center of the top surface of the round hole connector B106. The drain valve can be remotely controlled. Component 2 includes a drain valve 201, with a remote controller 202 connected to the top edge of the drain valve 201 and a manual valve 203 connected to the center of the drain valve 201. Pressure transmitter component 3 includes a pressure transmitter body 301, with a connecting pipe 302 connected to the center of the top surface of the pressure transmitter body 301. A connection port A303 is located on the left side of the connecting pipe 302, and a connection port B304 is located on the right side of the connecting pipe 302. A connection is also located at the center of the bottom surface of the pressure transmitter body 301. A nut rubber support 305 is attached, and a pressure transmitter port 306 is opened at the bottom of the nut rubber support 305. The salinity meter assembly 4 includes a salinity meter body 401. A sealing ring A402 is wrapped around the top edge of the surface of the salinity meter body 401. A cross handle A403 is connected to the top of the salinity meter body 401. The pH meter assembly 5 includes a pH meter body 501. A sealing ring B502 is wrapped around the top edge of the surface of the pH meter body 501. A cross handle B503 is connected to the top of the pH meter body 501.

[0027] Please see Figures 1-4When the wet deacidification system starts, the circulating liquid enters the pipeline and then the deacidification tower due to pump pressure. The salinity meter and pH meter are installed in their respective positions on the U-shaped housing 101, and the drain valve 201 is closed. The high-level inlet valve 102 of the circulating liquid is opened, and the circulating alkali solution enters the U-shaped housing 101 through the circulating liquid pipeline and the high-level inlet valve 102. Once the U-shaped housing 101 is full, the salinity meter and pH meter begin real-time measurement of the salinity and pH of the circulating liquid. When the liquid level reaches the height of the high-level outlet valve 105, it overflows from the U-shaped pipe and flows into the circulation tower, completing one loop. If the salinity meter or pH meter malfunctions, the high-level inlet valve 102 and the high-level outlet valve 105 of the circulating liquid are closed. The faulty salinity meter and pH meter are then removed and repaired. After the maintenance is completed, close the high-level inlet valve of the circulating fluid and the high-level outlet valve 105 of the circulating fluid. Install the instruments, open the high-level inlet valve 102 of the circulating fluid and the high-level outlet valve 105 of the circulating fluid, and put them into operation. Because there are salts or other precipitates in the circulating fluid, the U-tube is prone to blockage after a certain period of use. Close the high-level inlet valve 102 of the circulating fluid and the high-level outlet valve 105 of the circulating fluid. Open the drain valve 201. Remove the salinity meter and pH meter respectively and rinse the precipitates inside the U-shaped housing 101 with tap water. When the deacidification system malfunctions or stops, close the high-level inlet valve 102 of the circulating fluid and the high-level outlet valve 105 of the circulating fluid to ensure that there is a sufficient liquid level in the U-shaped housing 101 to protect the instruments from liquid loss that could cause the electrode bulbs to fail.

[0028] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0029] During operation, the salinity and pH measurements are taken in real time to ensure that the salinity and pH within the desulfurization tower remain within the design range, thus guaranteeing desulfurization efficiency. This effectively prevents corrosion of the salinity and pH meters by the circulating liquid, short circuits due to inlet water, or short circuits caused by hot gas condensate during operation. The salinity and pH meters are easy to maintain and replace, and will not cause the desulfurization system to shut down due to maintenance, ensuring stable and effective operation of the unit. The high-level inlet valve 102 of the circulating liquid controls the flow rate of the circulating liquid into the system, meeting the requirements for system operation and maintenance. This solves the problem that if the instruments malfunction and maintenance is required, the pump must be stopped, otherwise, the flue gas or circulating liquid will overflow, causing secondary pollution. The salinity and pH meters can be easily installed through the U-shaped housing 101, making the system... The system is independent of the desulfurization system. Since the inlet and outlet of the circulating liquid in the U-shaped shell 101 are both at high levels, a certain amount of liquid remains in the U-shaped shell after the wet desulfurization pump stops, which can soak the salinity meter and pH meter. The electrodes will not fail due to lack of liquid, thus preventing damage to the instruments. In addition, the circulating liquid high-level outlet valve 105 can ensure that the liquid level in the U-shaped shell 101 remains constant after the desulfurization pump stops. The drain valve 201 can periodically clean the salt deposited in the U-shaped shell 101, ensuring the measurement accuracy of the salinity meter and pH meter. In addition, a remote controller 202 can be installed at the drain valve 201 to remotely control the opening and closing of the valve, enabling real-time remote draining. Pressure transmitter components 3 are installed at the inlet and outlet valves respectively to adjust and control the discharge rate, preventing uneven discharge rate from affecting work efficiency.
