Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a device for improving the stability of online smoke detection. Background Art

[0002] Online flue gas monitoring is used to track and monitor the concentration and total amount of gaseous pollutants (such as sulfur dioxide, nitrogen oxides, etc.) and particulate matter emitted by air pollution sources in real time, and transmit relevant information to the competent authorities in real time to ensure that the pollutant concentration and total amount of the emitting enterprises meet the standards.

[0003] During testing, the flue gas analyzer is usually installed on the exhaust port and chimney. However, in actual use, there are the following shortcomings:

[0004] 1. When the flue gas is discharged, the temperature is high and the flow rate is fast. The probe is in direct contact with the high-speed flowing flue gas and is prone to shaking or even damage.

[0005] 2. The equipment is inconvenient to install and disassemble, which is not conducive to regular maintenance.

[0006] Therefore, we propose a device to improve the stability of online flue gas detection. Summary of the Invention

[0007] The purpose of the utility model is to solve the shortcomings of the prior art that when the flue gas is discharged, the temperature is high and the flow rate is fast, the probe is in direct contact with the high-speed flowing flue gas and is prone to shaking or even damage, the equipment is inconvenient to install and disassemble, and is not conducive to regular maintenance. A device is proposed to improve the stability of online flue gas detection.

[0008] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] A mounting ring is installed on the outer wall of the exhaust pipe, and a mounting plate is fixed to the outer wall of one side of the mounting ring. A flue gas analyzer is provided on the upper surface of the mounting plate, and a probe is provided at one end of the flue gas analyzer;

[0011] The device also includes a detection tube installed on one side of the smoke exhaust pipe, the detection tube being connected to the smoke exhaust pipe, a cooling tube and two solenoid valves being provided on the outer wall of the detection tube, the cooling tube being located between the two solenoid valves, an insert tube being fixedly passed through the outer wall of the detection tube, a sealing ring being provided on the inner wall of the insert tube, and one end of the probe passing through the insert tube and the sealing ring and extending into the detection tube;

[0012] A limiting mechanism is provided on one side of the mounting plate and is used to limit the position of the probe;

[0013] A positioning mechanism is provided on the upper surface of the mounting plate and is used for positioning the flue gas analyzer.

[0014] In one possible design, the limiting mechanism includes a limiting plate and two limiting grooves, which are symmetrically arranged on the outer wall of the probe. The limiting plate is slidably connected to the mounting plate, and the top of the limiting plate slides through the mounting plate and extends out of the upper surface of the mounting plate. The limiting plate and the limiting groove cooperate with each other, and a tension spring is fixed between the limiting plate and the mounting plate.

[0015] In a possible design, the positioning mechanism includes a positioning frame and two screws. The positioning frame is fixed on the upper surface of the mounting plate. The threads of the two screws pass through the upper surface of the mounting plate. The upper surfaces of the two screws are fixed with pressure blocks.

[0016] In a possible design, two rubber pads are provided on the top of the flue gas analyzer.

[0017] In a possible design, a connecting tube is fixedly passed through the outer wall of the detection tube, a temperature sensor is fixedly provided on the inner wall of the connecting tube, and a sealing cap is threadedly connected to one end of the connecting tube.

[0018] In a possible design, two obliquely arranged support rods are fixed to the bottom of the mounting plate, and the bottom ends of the two support rods are fixed with a same arc-shaped plate, which contacts the smoke exhaust pipe.

[0019] In this application, during the test, the solenoid valve is opened, and the flue gas is diverted from the exhaust pipe into the detection tube. The temperature sensor detects the flue gas temperature. If the temperature is too high, a cooling medium (tap water or other coolants can also be used) is introduced into the cooling tube to reduce the flue gas temperature. The flue gas composition is then analyzed by a flue gas analyzer.

[0020] During maintenance, rotate the pressure block to separate the pressure block and the rubber pad, then move the limit plate to separate the limit plate and the limit groove, then pull the probe out of the intubation tube, and then remove the flue gas analyzer for maintenance. After maintenance is completed, reinstall the flue gas analyzer.

[0021] Beneficial effects:

[0022] In the present invention, the device for improving the stability of online flue gas detection can shunt and cool the flue gas by setting multiple structures such as a cooling pipe, a solenoid valve and a detection pipe, thereby reducing the impact on the probe and improving the stability of the probe detection;

[0023] In the utility model, the device for improving the stability of online flue gas detection can facilitate the installation and disassembly of the flue gas analyzer and the probe by providing multiple structures such as a positioning frame, a screw and a pressing block, which is conducive to regular maintenance.

[0024] In the utility model, the flue gas can be diverted and cooled, the impact on the probe is reduced, the stability of the probe detection is improved, people can easily install and disassemble the flue gas analyzer and the probe, and it is conducive to regular maintenance.
