Description

Technical Field

[0001] The present invention relates to the technical field of industrial waste gas detection, and in particular to an industrial waste gas detection device and a detection method. Background Art

[0002] When testing industrial waste gas, it generally includes pre-treatment testing and post-treatment testing. The post-treatment testing is mainly to detect whether the treated waste gas meets the standards. The waste gas can only be discharged after meeting the standards. The common detection methods are continuous online detection and sampling detection. Continuous online detection is to perform continuous detection in the pipe through waste gas detection instruments. In this case, since the waste gas flows at a fast speed in the pipe, the waste gas flowing through the detection instrument changes greatly, resulting in more deviations in the detection results and prone to false alarms. Although sampling detection can accurately analyze the concentration of waste gas components, it cannot continuously detect the waste gas.

[0003] The publication number is CN116840425B, which is an automatic detection device for industrial waste gas, comprising a mounting bracket and an air inlet, wherein the air inlet is fixedly plugged in the side wall of the mounting bracket, an annular plate is sleeved on the outside of the air inlet, and mounting rings are integrally formed on the inner sides of the two side walls of the annular plate, and the two mounting rings are sealed and rotatably connected to the outer wall of the air inlet, and a plurality of detection cavities are provided on the inner wall of the annular plate, and an air inlet hole connected to one of the detection cavities is provided on the side wall of the air inlet. The present invention combines the advantages of continuous online detection and multi-point sampling detection, greatly improves the adequacy and accuracy of waste gas detection, and respectively measures the overall concentration of waste gas and the concentration of a single pollutant gas in the waste gas, with accurate detection, and automatically alarms when the waste gas treatment does not meet the standard, and at the same time, the waste gas can be refluxed for treatment to prevent the waste gas that does not meet the standard from flowing out and polluting the environment.

[0004] The above technical solution adopts a fixed structure setting, which cannot fully detect gases at different heights. At the same time, the continuous online detection and multi-point sampling detection schemes in the above solution are complex in structure and not conducive to use, so they need to be improved.

[0054] Among them, the extension and retraction of the first electric telescopic rod 13 can be controlled. When the piston rod of the first electric telescopic rod 13 contracts, the movable plate 11 can be moved toward the direction of the lifting frame assembly 2, and the inclined rod 12 can be gradually operated in a direction parallel to the lifting frame assembly 2, so that the cross bar 22 can be pushed to rise, so that the cross bar 22 drives the supporting platform assembly 3 to rise.

[0056] When the crossbar 22 is lifted or lowered, it can drive the slider 21 to be lifted or lowered in the corresponding lifting frame assembly 2 , thereby ensuring the stability of the lifting of the slider 21 .

[0057] In some embodiments, a first motor assembly 31 is installed at the upper end of the support platform assembly 3, and the lower end of the vertical shaft 33 is rotatably sleeved on the upper end of the support platform assembly 3. A first transmission assembly 32 is jointly installed on the output shaft of the first motor assembly 31 and the vertical shaft 33, and the upper end of the vertical shaft 33 is fixed to the lower end of the tube body 5.

[0058] Among them, the first transmission component 32 is composed of a belt and two pulleys, and a toothed structure is arranged on the belt and the two pulleys to ensure the stable transmission of power. The two pulleys are respectively fixed on the vertical shaft 33 and the output shaft of the first motor component 31. The staff can control the rotation of the first motor component 31, so that the vertical shaft 33 can drive the tube body 5 to rotate, and the axial direction of the two connecting pipes 6 on the tube body 5 can be the same as the gas flow direction, and other flow directions can be controlled by rotating the fan blade part 63, so as to fully realize that the gas can flow in the tube body 5.

[0059] In some embodiments, two connecting tubes 6 are each installed with an electric control valve 64 on one end located on the outside of the tube body 5, and the tube body 5 is located between the two electric control valves 64. A second motor assembly 61 is installed on one end of one of the connecting tubes 6 located on the outside of the tube body 5, and a fan blade member 63 is provided on the connecting tube 6. The fan blade member 63 is arranged on the outside of one of the connecting tubes 6, and a second transmission assembly 62 is jointly installed on the fan blade member 63 and the output shaft of the second motor assembly 61.

[0060] Among them, the electric control valve 64 is connected to the corresponding control component so that the two electric control valves 64 are opened and closed synchronously, so as to control the flow of gas. Through the flow of gas, the gas can be effectively made to flow quickly in the tube body 5, so as to fully make the gas in the tube body 5 and the gas in the sampling area the same, and the second motor assembly 61 is connected to the external corresponding control equipment. At the same time, the second transmission assembly 62 is composed of a belt and two pulleys, and a toothed structure is provided on the belt and the two pulleys to ensure the stability of power transmission, and the two pulleys are respectively fixed on the fan blade member 63 and the output shaft of the second motor assembly 61 to effectively perform transmission operations, so that the fan blade member 63 can drive the gas flow, so that the gas enters the tube body 5 from the connecting pipe 6 and the opening 65 on this side, and then outputs through the opening 65 and the connecting pipe 6 on the other side.

[0061] In some embodiments, a second electric telescopic rod 52 is provided at both ends of the tube body 5 , the piston rods of the two second electric telescopic rods 52 are located in the tube body 5 , and the piston rod ends of the two second electric telescopic rods 52 are respectively fixed to two extrusion sealing plates 51 .

[0062] Among them, the second electric telescopic rod 52 is connected to the corresponding control component to control the extension and retraction of the piston rod of the second electric telescopic rod 52, so that the second electric telescopic rod 52 can drive the extrusion sealing plate 51 to move in the tube body 5. The relative position relationship between the extrusion sealing plate 51, the contact plate 53 and the connecting pipe 6 can be controlled by the movement of the extrusion sealing plate 51. When the contact plate 53 and the connecting pipe 6 are in contact with each other and the extrusion sealing plate 51 moves on the connecting pipe 6, the opening 65 on the connecting pipe 6 can be located between the extrusion sealing plate 51 and the contact plate 53 on the same side, which can facilitate the gas to enter the tube body 5 through the opening 65, and facilitate the gas to enter between the two extrusion sealing plates 51 through the opening 65 on one side, and will be discharged through the opening 65 on the other connecting pipe 6. At the same time, when sampling gas, ensure that the electric control valve 64 is opened to facilitate gas flow. When the sampling is completed, the two electric control valves 64 can be closed to effectively perform sampling.

[0063] In some embodiments, two sliding rods 55 are slidably sleeved on the extrusion sealing plate 51, and the two sliding rods 55 are fixedly connected to the contact plate 53 on the same side thereof. A resistance spring member 54 is sleeved on the sliding rod 55, and the resistance spring member 54 is arranged on the side of the extrusion sealing plate 51 away from the contact plate 53, and the two ends of the resistance spring member 54 are respectively fixed on the extrusion sealing plate 51 and the sliding rod 55.

[0064] Among them, when the second electric telescopic rod 52 drives the extrusion sealing plate 51 to move toward the direction of the connecting tube 6, a circular hole is set in the middle of the extrusion sealing plate 51. When the extrusion sealing plate 51 moves toward the connecting tube 6, the connecting tube 6 will be inserted into the circular hole and contact the contact plate 53, so that the contact plate 53 and the extrusion sealing plate 51 can be separated, and the resistance spring member 54 can be compressed; at the same time, when the two extrusion sealing plates 51 move relative to each other, the resistance spring member 54 can quickly pull the sliding rod 55 to move in the extrusion sealing plate 51, so that the contact plate 53 can move toward the extrusion sealing plate 51 on the same side, so that the extrusion sealing plate 51 and the contact plate 53 can contact each other, and a sealing rubber layer is coated on the contact plate 53 to improve the sealing effect and avoid air leakage.

[0065] In some embodiments, two sealing plates 46 are provided in the detection chamber 41 from top to bottom, a fixing rod 47 is commonly fixed between the two sealing plates 46 in the same detection chamber 41 , and the two sealing plates 46 in the same detection chamber 41 are arranged between two exhaust pipes 45 in the detection chamber 41 .

[0066] The fixing rods 47 can fully enable the two fixing rods 47 to move synchronously, and the sealing rubber pad and other components covered on the sealing plate 46 can be easily contacted with the corresponding exhaust pipe 45 to effectively seal and avoid leakage.

[0067] In some embodiments, a limit rod 44 is slidably installed on the sealing plate 46 at the lower end in the same detection cavity 41, the lower end of the limit rod 44 is fixed on the tube body 5, and a reset spring 43 is sleeved on the limit rod 44. The reset spring 43 is located between the two sealing plates 46 on the same side, and the two ends of the reset spring 43 are respectively fixed on the limit rod 44 and the sealing plate 46 at the lower end.

[0068] Among them, the two sealing plates 46 in the detection cavity 41 are arranged from the inside to the outside, and the limiting rod 44 is slidably sleeved on the inner ring of the sealing plate 46. At the same time, during preparation, the two exhaust pipes 45, two sealing plates 46 and the fixing rod 47 located in the same detection cavity 41 are coaxially arranged to facilitate accurate resistance sealing.

[0069] Based on the above example, in the initial state, the exhaust pipe 45 and the sealing plate 46 located in the inner circle are in conflict with each other. When the two extruded sealing plates 51 in the tube body 5 move relative to each other, the gas can be pressurized, and the gas squeezes the sealing plate 46 located in the inner circle, causing it to squeeze the reset spring 43, so that the gas can enter the detection cavity 41. At the same time, when the sealing plate 46 of the inner circle is squeezed and lifted, the sealing plate 46 and the exhaust pipe 45 located in the outer circle will be in conflict with each other to achieve sealing operation, so that the gas between the extruded sealing plates 51 can enter the detection cavity 41, so that the detector assembly 42 can detect the gas.

[0070] In some embodiments, the diameter of the sealing plate 46 is greater than the diameter of the exhaust pipe 45 .

[0071] The sealing plate 46 can be ensured to quickly seal the exhaust pipe 45, and a rubber pad can be coated on the sealing plate 46 to avoid gas leakage.

[0078] S6, gas detection: With the relative movement of the two extrusion sealing plates 51, the gas enters the exhaust pipe 45 and contacts the sealing plate 46, so that the sealing plate 46 located at the inner circle and the exhaust pipe 45 arranged on the tube body 5 are separated, and the sealing plate 46 located at the outer circle can contact the exhaust pipe 45 located at the outer circle to seal, so that the gas enters the detection cavity 41, and the detector assembly 42 can detect the gas entering the detection cavity 41;

[0079] S7. Exhaust: When the two extruded sealing plates 51 are in contact with each other, the gas between the extruded sealing plates 51 cannot continue to exert pressure on the inner ring sealing plate 46.
