Description

Technical Field

[0001] This utility model relates to the field of compressed air buffering technology, and in particular to a compressed air buffering device for online flue gas monitoring equipment. Background Technology

[0002] A compressed air buffer device for flue gas online monitoring equipment is a device used in flue gas online monitoring systems to buffer compressed air, ensuring stable system operation and accurate measurements. It typically utilizes the compressibility of gas and changes in container volume to achieve the buffering function. Common types include buffer tanks. When compressed air enters the buffer tank, due to its volume, the gas is temporarily stored and diffused within the tank, thereby buffering and stabilizing pressure and flow rate.

[0003] However, in existing technologies, unstable compressed air pressure in some devices leads to fluctuations in sampling flow, making it impossible to perform stable and accurate sampling as required by standards. The collected flue gas samples cannot accurately reflect the actual flue gas conditions, causing deviations in subsequent analysis results and failing to provide reliable data for environmental supervision. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a compressed air buffer device for online flue gas monitoring equipment. A pressure gauge monitors the pressure inside the tank in real time. Once the pressure exceeds a preset limit, the pressure relief valve automatically opens to release excess gas, maintaining pressure stability and preventing damage to the equipment due to overpressure. Power is supplied through the electromagnetic coil at the top of the pressure reducer, activating it to adjust the compressed air to a suitable pressure and purity before delivering it to the flue gas analyzer, ensuring accurate measurement.

[0005] To achieve the above objectives, a compressed air buffer device for an online flue gas monitoring equipment is provided, comprising a base, a compressed air storage tank fixedly connected to the top of the base, a first air inlet pipe fixedly connected inside the compressed air storage tank, a third air inlet pipe fixedly connected to the top of the first air inlet pipe, a sleeve fixedly connected to one end of the third air inlet pipe, a vent plate fixedly connected inside the sleeve, a blade rotatably connected to the outside of the vent plate, a filter cylinder threaded inside the sleeve, and a sponge block disposed inside the filter cylinder.

[0006] According to the compressed air buffer device for the flue gas online monitoring equipment, a second air inlet pipe is fixedly connected to the bottom of the first air inlet pipe, and a compressor is fixedly connected to one end of the second air inlet pipe.

[0007] According to the compressed air buffer device for flue gas online monitoring equipment, a pressure gauge is fixedly connected to the top of the compressed air storage tank, an air outlet pipe is fixedly connected to the top of the compressed air storage tank, and a vent valve is fixedly connected to the outside of the air outlet pipe.

[0008] According to the compressed air buffer device for an online flue gas monitoring device, a collar is fixedly connected to the outside of the first air inlet pipe, and multiple bolts are threadedly connected to the top of the collar.

[0009] According to the compressed air buffer device for flue gas online monitoring equipment, a support block is fixedly connected to the top of the collar, a pressure reducer is fixedly connected to the top of the support block, and a first rotating rod is fixedly connected to the top of the support block.

[0010] According to the compressed air buffer device for flue gas online monitoring equipment, an electromagnetic coil is fixedly connected to the outside of the first rotating rod, an interface is fixedly connected to the outside of the pressure reducer, and a switch is rotatably connected to the outside of the interface.

[0011] According to the compressed air buffer device for an online flue gas monitoring device, a smoke analyzer is fixedly connected to one end of the first air inlet pipe, and the bottom of the smoke analyzer is fixedly connected to the base.

[0012] According to the compressed air buffer device for flue gas online monitoring equipment, a drain pipe is fixedly connected to the outside of the compressed air storage tank, a second rotating rod is rotatably connected inside the drain pipe, a piston is fixedly connected to one end of the second rotating rod, and a limit block is fixedly connected inside the drain pipe.

[0013] Beneficial effects:

[0014] 1. The compressed air storage tank has two air inlet channels. The first inlet pipe is connected to the air compressor pipeline to provide the regular air source; the second inlet pipe is connected to the backup compressor, which will start in case of failure of the main air source to ensure uninterrupted air supply. A pressure gauge and a pressure relief valve are installed on the top of the compressed air storage tank. The pressure gauge monitors the pressure inside the tank in real time. Once the pressure exceeds the preset limit, the pressure relief valve will automatically open to release excess gas to maintain pressure stability and prevent equipment damage due to overpressure.

[0015] 2. A drain valve is installed at the bottom of the compressed air tank. When the water inside the tank reaches a certain level, rotating the second rotating rod causes the piston at the bottom to disengage from the groove inside the limit block, allowing the water to drain out through the drain pipe and preventing water from entering the air-using equipment and affecting its normal operation. The outlet pipe of the compressed air tank is connected to two air-using terminals: one is directly connected to the chimney sampling device. When smoke enters the sleeve, it causes the internal blades to rotate, thereby crushing the particulate matter in the smoke, which then enters the filter cartridge to provide a stable air source for sampling. The other terminal is connected to the interface through a filter pressure reducing device and an external wire. Then, turning on the switch allows power to enter the pressure reducing device through the electromagnetic coil at the top, thus starting the pressure reducing device. After adjusting the compressed air to a suitable pressure and purity, it is delivered to the smoke analyzer to ensure accurate measurement by the smoke analyzer.

[0033] Specifically: the external wire is connected to interface 21, and then switch 22 is turned on so that the power supply enters the interior of pressure reducer 18 through electromagnetic coil 20 at the top of pressure reducer 18, thereby starting pressure reducer 18.

A pressure gauge 3 and a pressure relief valve 5 are installed on the top of the compressed air storage tank 2. The pressure gauge 3 monitors the pressure inside the tank in real time. Once the pressure exceeds the preset limit, the pressure relief valve 5 will automatically open, releasing excess gas through the outlet pipe 4 to maintain pressure stability and prevent equipment damage due to overpressure. A drain pipe 6 is installed at the bottom of the compressed air storage tank 2. When the water accumulation inside the tank reaches a certain amount, rotating the second rotating rod 23 causes the piston 24 at the bottom to disengage from the groove inside the limit block 24, allowing the water to drain out through the drain pipe 6, preventing water from entering the air-using equipment and affecting its normal operation. The outlet pipe of the compressed air storage tank 2 is connected to two gas terminals: one is directly connected to the chimney sampling device. When the smoke enters the sleeve 10, the internal blade 14 will rotate, thereby crushing the particulate matter in the smoke, and then it enters the filter cartridge 15 to provide a stable air source for sampling. The other terminal is connected to the interface 21 through the filter pressure reducing device and an external wire. Then, the switch 22 is turned on so that the power supply enters the inside of the pressure reducing device 18 through the electromagnetic coil 20 at the top of the pressure reducing device, thereby starting the pressure reducing device 18. After adjusting the compressed air to a suitable pressure and purity, it is delivered to the smoke analyzer to ensure the accurate measurement of the smoke analyzer.
