Description

Technical Field

[0001] This utility model relates to the field of flue gas monitoring technology, and in particular to a device for detecting volatile organic compounds in exhaust gas. Background Technology

[0002] Flue gas monitoring refers to the real-time or periodic monitoring of waste gas emitted during industrial production processes. The main pollutants monitored include particulate matter and compounds. These particulate matter mainly come from industries such as coal combustion, metallurgy, and building materials. The purpose of flue gas monitoring is to monitor the concentration and total amount of gaseous pollutants and particulate matter emitted from air pollution sources to ensure that emissions meet environmental protection standards. In places such as waste incineration power plants and thermal power plants, flue gas is generally emitted through chimneys, and the flue gas from the chimneys needs to be monitored during operation.

[0003] Existing flue gas monitoring equipment has the following drawbacks: Existing flue gas monitoring equipment typically uses a fixed structure installed on the side of the flue gas tower. To obtain the flue gas detection results of the emission section, the equipment is usually installed high up, making installation and maintenance inconvenient. Some floating monitoring equipment using hydrogen balloons is easily affected by wind, causing the balloons to drift away from the emission section of the flue gas tower, thus affecting the monitoring results. Therefore, we propose a new volatile organic compound (VOC) detection device for exhaust gas. Utility Model Content

[0004] The main purpose of this utility model is to provide a device for detecting volatile organic compounds in exhaust gas. By using a floating mechanism set on the side of the chimney and a floating airbag as a carrier, the device can limit the displacement range and ensure that it is located in the exhaust section of the chimney, thereby improving the monitoring accuracy and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for detecting volatile organic compounds in exhaust gas includes a chimney and a floating mechanism. The floating mechanism is located on the side of the chimney and includes a lower mounting base, an upper mounting base, a positioning steel rope, a collar, a motor, a reel, a steel wire rope, an airbag, and a connecting rope. The lower mounting base and the upper mounting base are fixed at their corresponding positions at the bottom and top of the side of the chimney, respectively. A positioning steel rope is vertically arranged between the lower mounting base and the upper mounting base, and a collar is sleeved around the outer periphery of the positioning steel rope. A motor is installed inside the lower mounting base, and a reel is installed at the power output end of the motor. A steel wire rope is wound around the outer periphery of the reel on one side of the lower mounting base and connected to the collar through the steel wire rope. An airbag is located on one side of the collar and is connected to the collar through a connecting rope.

[0006] Furthermore, it also includes a monitoring mechanism. The monitoring mechanism is located at the bottom of the airbag and includes a loading seat, a ventilation chamber, an infrared gas analyzer, and a flue gas monitor. The loading seat is adhered to the bottom of the airbag, and a horizontal ventilation chamber is formed inside the loading seat. The infrared gas analyzer and the flue gas monitor are installed inside the loading seat, and the detection ends of both extend into the ventilation chamber. A loading seat is located at the bottom of the airbag, and the flue gas monitoring instruments are installed inside the loading seat. When the airbag is filled with hydrogen and rises to the top of the chimney, some of the flue gas will pass through the ventilation chamber inside the loading seat as it is emitted. While passing through the ventilation chamber, the infrared gas analyzer inside the loading seat can detect SO2 and NO in the flue gas. X The flue gas monitor can detect particulate matter in flue gas, including CO, and can monitor and treat flue gas discharged from the flue tower to ensure that the emitted flue gas meets environmental protection requirements. The detection instruments inside the mounting base can also be flexibly adjusted and selected according to different locations and usage needs to meet different usage requirements.

[0007] Furthermore, connecting rings are welded to both ends of the collar and the bottom of the loading seat, and the ends of the connecting rope and the wire rope are tied to the outer periphery of the connecting ring; the connecting ring structure plays a positioning and connecting role, and is used to tie the ends of the wire rope and the connecting rope.

[0008] Furthermore, a communication cable is wound around the outer circumference of a spool inside the lower mounting base. One end of the communication cable is connected to the communication terminals of the infrared gas analyzer and the smoke and dust monitor. The communication cable can transmit and communicate monitoring data and provide real-time feedback to the control terminal. A slip ring structure is provided at the end of the spool on one side of the communication cable to ensure the normal winding of the communication cable.

[0009] Furthermore, an inflation tube is integrally formed on one side of the airbag; the inflation tube is used to fill and release hydrogen gas, and its opening and closing are controlled by an end piston.

[0010] Furthermore, a battery compartment is provided at the bottom of the loading seat, and the power supply end of the battery compartment is connected to the power consumption end of the internal components of the loading seat; the battery compartment is used to hold batteries to supply power to the power consumption components.

[0011] Compared with the prior art, this utility model has the following advantages: An upper mounting base and a lower mounting base are respectively provided on the top and bottom sides of the chimney. A positioning steel rope is vertically fixed between the lower and upper mounting bases, and a collar is fitted around the outer circumference of the positioning steel rope. One side of the collar is connected to the reel via a steel wire rope, and the other side is connected to the airbag via a connecting rope. Before use, the detection instrument is installed inside the loading base, and hydrogen is simultaneously filled into the airbag. After inflation, the airbag floats up, the steel wire rope is released, and during the airbag's ascent, the collar moves upward around the outer circumference of the positioning steel rope until the airbag reaches the top of the chimney. At this point, the flue gas discharged from the chimney can be detected and analyzed. Because the collar is restricted by the positioning steel rope, the displacement of the airbag is limited and unaffected by wind, keeping it always near the top of the chimney, thus maintaining detection accuracy. When it is necessary to replace or maintain the detection equipment, the steel wire rope can be wound up by a motor-controlled reel, which improves detection accuracy and facilitates inspection and maintenance. A loading seat is located at the bottom of the airbag, and the loading seat contains flue gas monitoring instruments. When the airbag is filled with hydrogen and rises to the top of the chimney, some of the flue gas will pass through the ventilation chamber inside the loading seat as it passes through the ventilation chamber. As it passes through the ventilation chamber, the infrared gas analyzer inside the loading seat can detect SO2 and NO in the flue gas. X The flue gas monitor can detect particulate matter in flue gas, including CO, and can monitor and treat flue gas discharged from the flue tower to ensure that the emitted flue gas meets environmental protection requirements. The detection instruments inside the mounting base can also be flexibly adjusted and selected according to different locations and usage needs to meet different usage requirements.

The lower mounting base 201 and the upper mounting base 202 are fixed at their corresponding positions at the bottom and top of the side of the chimney 1, respectively. The lower mounting base 201 and the upper mounting base 202 are connected to each other... A positioning steel rope 203 is vertically arranged between the mounting bases 202, and a collar 204 is sleeved around the outer periphery of the positioning steel rope 203. A motor 206 is installed inside the lower mounting base 201, and a reel 207 is installed at the power output end of the motor 206.

An airbag 210 is arranged on one side of the collar 204, and the airbag 210 is connected to the collar 204 through a connecting rope 212.

[0018] The system also includes a monitoring mechanism 3. The monitoring mechanism 3 is located at the bottom of the airbag 210. The monitoring mechanism 3 includes a loading seat 301, a ventilation cavity 302, an infrared gas analyzer 303, and a smoke and dust monitoring instrument 304.

The infrared gas analyzer 303 and the smoke and dust monitoring instrument 304 are installed inside the loading seat 301. Both the detection end of the 3 and the flue gas monitor 304 extend into the ventilation chamber 302. A loading seat 301 is located at the bottom of the airbag 210, and the flue gas monitoring instrument is installed inside the loading seat 301. When the airbag 210 is filled with hydrogen and rises to the top of the chimney 1, some of the flue gas will pass through the ventilation chamber 302 inside the loading seat 301 as it is emitted. While passing through the ventilation chamber 302, the infrared gas analyzer 303 inside the loading seat 301 can detect SO2 and NO in the flue gas. X The flue gas monitor 304 can detect particulate matter in flue gas, including CO, and can detect and treat the flue gas discharged from the flue gas tower 1 to ensure that the emitted flue gas meets environmental protection requirements. The internal detection instruments of the loading base 301 can also be flexibly adjusted and selected according to different places and usage needs to meet different usage requirements.

[0019] The collar 204 has connecting rings 205 welded to its upper and lower ends and to the bottom of the loading seat 301. The ends of the connecting rope 212 and the wire rope 208 are tied to the outer periphery of the connecting ring 205. A communication cable 209 is wound around the outer periphery of the spool 207 on one side inside the lower mounting seat 201. One end of the communication cable 209 is connected to the communication terminals of the infrared gas analyzer 303 and the smoke and dust monitor 304. The connecting ring 205 serves as a positioning and connecting element, used to tie the ends of the wire rope 208 and the connecting rope 212. The communication cable 209 enables the transmission and communication of monitoring data, providing real-time feedback to the control terminal. A slip ring structure is provided at the end of the spool 207 on one side of the communication cable 209 to ensure the normal winding of the communication cable 209.

[0020] The airbag 210 has an integrally formed inflation tube 211 on one side; the inflation tube 211 is used to fill and release hydrogen, and its opening and closing are controlled by an end piston.

[0021] The loading base 301 has a battery compartment 305 at its bottom. The power supply end of the battery compartment 305 is connected to the power consumption end of the components inside the loading base 301.

[0022] It should be noted that this utility model is a device for detecting volatile organic compounds in exhaust gas. In use, an upper mounting base 202 and a lower mounting base 201 are respectively provided on the top and bottom sides of the chimney 1. A positioning steel rope 203 is vertically fixed between the lower mounting base 201 and the upper mounting base 202, and a collar 204 is fitted around the outer circumference of the positioning steel rope 203. One side of the collar 204 is connected to a reel 207 via a steel wire rope 208, and the other side is connected to an airbag 210 via a connecting rope 212. Before use, the detection instrument is installed inside the loading seat 301, and hydrogen is simultaneously filled into the airbag 210. After inflation, the airbag 210 floats up, and the steel wire rope 208 is released. During the ascent of the airbag 210, the collar 204 moves upward around the positioning steel rope 203 until the airbag 210 reaches the top of the chimney 1, at which point the exhaust gas from the chimney 1 can be detected. The flue gas in the section is detected and analyzed. Simultaneously, because the collar 204 is restricted by the positioning steel rope 203, the displacement of the airbag 210 is limited and unaffected by wind force, remaining at the top of the chimney 1, thus maintaining detection accuracy. When replacement or maintenance of the detection equipment is required, the reel 207 is controlled by the motor 206 to wind up the steel wire rope 208, improving detection accuracy while facilitating inspection and maintenance. A loading seat 301 is located at the bottom of the airbag 210, housing a flue gas monitoring instrument. When the airbag 210 is filled with hydrogen and rises to the top of the chimney 1, some of the flue gas passes through the ventilation chamber 302 inside the loading seat 301. While passing through the ventilation chamber 302, the infrared gas analyzer 303 inside the loading seat 301 can detect SO2 and NO in the flue gas. XThe flue gas monitor 304 can detect particulate matter in flue gas, including CO, and can detect and treat the flue gas discharged from the flue gas tower 1 to ensure that the emitted flue gas meets environmental protection requirements. The internal detection instruments of the loading base 301 can also be flexibly adjusted and selected according to different places and usage needs to meet different usage requirements.
