Description

Technical Field

[0001] This utility model relates to the field of environmental protection desulfurization technology, and more specifically to a pH measuring device for desulfurization water bed slurry in a stoker furnace. Background Technology

[0002] Currently, wet flue gas desulfurization (FGD) technology is the most widely used desulfurization process among coal-fired boiler flue gas desulfurization technologies. In recent years, some small and medium-sized coal-fired enterprises mainly engaged in heating have begun to apply calcium-based wet FGD technology, which has higher desulfurization efficiency. The pH value of the desulfurization slurry is an important operating parameter of the calcium-based wet FGD system, which has a significant impact on desulfurization efficiency and gypsum quality. During the normal operation of the desulfurization system, the pH value of the desulfurization slurry in the desulfurization water bed is generally controlled between 5.2 and 6. Accurate and reliable monitoring of the pH value of the desulfurization slurry is a prerequisite for the stable operation of the desulfurization system.

[0003] However, the traditional method for measuring the pH value of the slurry in a desulfurization water bed is to directly install the pH measuring device on the desulfurization water bed. Because the desulfurization slurry contains tiny gypsum particles and impurities such as oil and ash in the flue gas, these impurities will adhere to the surface of the pH measuring device, forming an insulating layer that hinders ion transmission and reduces measurement accuracy. In existing technologies, a branch pipe is connected to one side of the desulfurization water bed, and the pH measuring device is inserted into the branch pipe. If the flow rate of the slurry inside the desulfurization water bed into the branch pipe is too high, it can easily cause erosion and wear to the pH measuring device, shortening its service life.

[0004] Therefore, how to provide a slurry pH measuring device that can reduce impurity adhesion and reduce the direct scouring and wear of the pH measuring component by the slurry flow rate is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a pH measuring device for desulfurization water bed slurry in a stoker-fired furnace, aiming to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pH measuring device for desulfurization water bed slurry in a stoker furnace includes:

[0008] Desulfurization water bed;

[0009] A sampling sedimentation tank, the inlet of which is connected to the desulfurization water bed via a first connecting pipe;

[0010] The measuring tank contains a pH measuring component and has an inlet at the bottom. The inlet is connected to the outlet of the sampling sedimentation tank via a second connecting pipe. Staggered baffles are fixed on the opposite inner sidewalls of the measuring tank, and the baffles are located below the pH measuring component.

[0011] Through the above technical solution, this utility model provides a pH measuring device for desulfurization water bed slurry in a stoker furnace. By setting up a sampling sedimentation tank, the slurry is pre-sedied before entering the measuring tank, effectively removing tiny gypsum particles, oil, ash, and other impurities from the slurry. This reduces the possibility of impurities adhering to the surface of the pH measuring component, thereby improving the measurement accuracy. The staggered baffles inside the measuring tank can change the flow direction of the slurry, creating turbulence within the tank, dispersing the impact force of the slurry, reducing direct scouring of the pH measuring component, decreasing wear on the component, and extending its service life.

[0012] Preferably, in the above-mentioned pH measuring device for desulfurization water bed slurry in a stoker-fired furnace, a sampling valve is installed on the first connecting pipe, a sampling regulating valve is installed at the end of the second connecting pipe near the sampling sedimentation tank, and an inlet valve is installed at the end of the second connecting pipe near the measuring tank. By setting the sampling valve, sampling regulating valve, and inlet valve, the slurry flow rate from the desulfurization water bed to the sampling sedimentation tank and from the sampling sedimentation tank to the measuring tank can be precisely controlled, ensuring a stable supply of slurry in the measuring tank and avoiding measurement errors caused by unstable flow rate.

[0013] Preferably, in the aforementioned pH measuring device for desulfurization water bed slurry in a stoker-fired furnace, a flushing pipe is connected to the second connecting pipe, located between the sampling regulating valve and the injection valve, and a flushing water valve is installed on the flushing pipe. After the measuring tank has been used for a period of time, a small amount of impurities may remain or adhere to the inner wall of the pipe. The flushing pipe can periodically flush the second connecting pipe to prevent pipe blockage, ensure the normal flow of the slurry, and ensure the long-term stable operation of the measuring device.

[0014] Preferably, in the aforementioned pH measuring device for desulfurization water bed slurry in a stoker-fired furnace, the pH measuring component includes a pH meter and a pH electrode. The pH meter is installed above the measuring tank, and the top end of the pH electrode is electrically connected to the pH meter via a wire, while its bottom end extends into the interior of the measuring tank. The combination of the pH meter and the pH electrode can accurately measure the pH value of the slurry in the measuring tank, providing reliable data support for the operation of the desulfurization system and ensuring desulfurization efficiency and gypsum quality.

[0015] Preferably, the pH measuring device for desulfurization water bed slurry in a stoker-fired furnace further includes the aforementioned pH measuring device for desulfurization slurry, and a waste sample tank, a waste liquid storage tank, and a desulfurization slurry treatment unit connected in sequence. The measuring tank has a drain outlet, which is connected to the waste sample tank via a drain pipe. The desulfurization slurry treatment unit is connected to the desulfurization water bed via a third connecting pipe. The pH measuring device monitors and controls the pH value of the desulfurization slurry in real time, ensuring that the pH value remains within a suitable range. This stabilizes the operation of the entire desulfurization system, improves desulfurization efficiency, and reduces environmental pollution. Combining the pH measuring device with the waste sample tank, waste liquid storage tank, and desulfurization slurry treatment unit forms a complete desulfurization slurry circulation system, enabling effective collection and treatment of waste samples and waste liquid, achieving the recycling of desulfurization slurry, improving resource utilization, and reducing production costs.

Both the overflow pipe and the regulating pipe have their outlet ends connected to a fourth connecting pipe, the outlet end of which communicates with the waste sample tank. The overflow pipe prevents the slurry in the measuring tank from overflowing due to excessive liquid level, avoiding waste and potential environmental pollution, while ensuring a stable liquid level in the measuring tank. The regulating pipe facilitates adjustment of the liquid level in the measuring tank; by controlling the valve on the regulating pipe, the liquid level in the measuring tank can be flexibly adjusted, ensuring the pH measuring component is always in a suitable measuring position, further improving measurement accuracy.

[0017] Preferably, in the aforementioned pH measuring device for desulfurization water bed slurry in a stoker-fired furnace, a level regulating valve is installed on the regulating pipeline, and a discharge valve is installed on the drain pipeline. The installation of the level regulating valve makes the adjustment of the liquid level in the measuring tank more precise and convenient. Operators can accurately control the liquid level in the measuring tank by adjusting the opening of the level regulating valve according to actual needs, ensuring that the pH measuring component operates under optimal working conditions. The level regulating valve can be combined with an automated control system to achieve automatic adjustment of the liquid level in the measuring tank, further improving the system's automation level and operational stability. The discharge valve facilitates the discharge of waste liquid from the measuring tank into a waste sample pool, simplifying the operation process and improving system operating efficiency.

By setting up the aeration tank, slurry preparation tank, and sedimentation tank, a complete desulfurization slurry treatment process is formed, enabling the waste sample and waste liquid to be fully treated, improving the quality of the desulfurization slurry, and providing a guarantee for the stable operation of the desulfurization system. The aeration tank can aerate the waste sample to remove harmful gases; the slurry preparation tank can slurry the waste sample to achieve a suitable concentration and properties; and the sedimentation tank can further precipitate impurities in the waste sample, improving the purity of the desulfurization slurry, thereby improving the desulfurization efficiency of the entire desulfurization system.

The isolation valve prevents backflow of waste samples and waste liquid during transport, ensuring that waste samples and waste liquid can be smoothly transported from the waste sample tank to the waste liquid storage tank, avoiding system blockage and measurement errors caused by backflow. The installation of the waste sample circulation pump and the slurry circulation pump improves the transport efficiency of waste samples and desulfurization slurry, ensuring the normal operation of the entire desulfurization slurry circulation system and reducing production delays caused by poor transport.

[0020] Preferably, the pH measuring device for desulfurization water bed slurry in a stoker furnace further includes a wastewater tank connected to the waste sample tank, and a drain valve is installed on the connecting pipeline between the wastewater tank and the waste sample tank.

By combining the pH measuring device with the waste sample tank, waste liquid storage tank, and desulfurization slurry treatment unit, a complete desulfurization slurry circulation system is formed, realizing the effective collection and treatment of waste samples and waste liquid, improving resource utilization, and reducing production costs.

[0025] 4. This utility model prevents the overflow and contamination of the slurry in the measuring tank by setting up overflow and regulating pipelines, while ensuring the stability of the liquid level in the measuring tank.

[0044] The embodiments of this utility model are as follows:
