Description

Technical Field

[0001] This utility model relates to the technical field of environmental monitoring, and in particular to a multi-purpose dust or flue gas sampling tube. Background Technology

[0002] In environmental monitoring, exhaust gas monitoring from exhaust stacks requires the use of various sampling tubes (commonly known as smoke guns) depending on the monitoring items. For example, there are ultra-low particulate matter sampling tubes for collecting ultra-low particulate matter, filter clip sampling tubes for collecting particulate matter with higher concentrations, sampling tubes for collecting flue gas, and sampling tubes for measuring flue gas velocity, flue gas temperature, and humidity (resistivity-capacitance method).

[0003] Currently, traditional multi-purpose dust or flue gas sampling tubes often have a single function, and each sampling tube can only be designed for a specific monitoring project. This means that when conducting multi-project monitoring, the testing personnel need to carry multiple sets of sampling equipment, which not only increases the burden of carrying equipment, but also requires repeated disassembly and assembly of sampling tubes when switching between different projects, which prolongs the operation time and reduces the monitoring efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a multi-purpose dust or flue gas sampling tube. Through the design of the installation mechanism, the sampling tube can be stably installed on the testing device, and the disassembly and assembly process is simple and quick, without the need for bolts or other fasteners, thereby reducing the labor intensity of operators, reducing the sampling workload, and improving work efficiency.

[0006] To achieve the above objectives, the first aspect of this utility model provides a multi-purpose smoke or flue gas sampling tube, comprising: a controller, a sampling tube, a sampling head, and an installation mechanism.

The anti-slip block is sleeved on the outside of the connecting base. The fixing ball is installed inside the connecting base, and the fixing ring is sleeved on the outer wall of the connecting base.

[0007] In addition, the multi-purpose dust or flue gas sampling tube proposed above according to this utility model may also have the following additional technical features: Specifically, the sampling tube is equipped with a sampling assembly inside, which includes an air extraction tube, a heat tracing tube, a heat tracing tube temperature sensor, a power cord, a smoke temperature sensor signal line, and a Pitot tube conduit. The air extraction tube is installed inside the sampling tube, the heat tracing tube is installed inside the air extraction tube, the heat tracing tube temperature sensor is installed inside the sampling tube, the power cord is installed inside the sampling tube, and the Pitot tube conduit is installed inside the sampling tube.

[0008] Specifically, a connecting pipe is installed at the bottom of the controller.

[0010] Specifically, the outer wall of the grip is fitted with anti-slip pads.

[0011] Specifically, a positioning block is fitted on the outer wall of the sampling tube.

[0016] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] A multi-purpose dust or flue gas sampling tube according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown, a multi-purpose dust or flue gas sampling tube according to an embodiment of the present invention includes: a controller 1, a sampling tube 2, a sampling head 3, and an installation mechanism 5.

[0019] One end of the sampling tube 2 is connected to the controller 1, and the sampling head 3 is connected to the other end of the sampling tube 2. The installation mechanism 5 includes a mounting base 51, a connecting base 53, a locking block 54, a spring 55, an anti-slip block 56, a fixing ball 57, and a fixing ring 58.

[0020] The mounting base 51 is fitted onto the outside of the sampling tube 2. A slot 52 is provided on the outer wall of the mounting base 51. The connecting base 53 is fitted onto the outside of the mounting base 51. The locking block 54 is installed inside the mounting base 51 and the connecting base 53 respectively. A spring 55 is fitted onto the outside of the locking block 54. The anti-slip block 56 is fitted onto the outside of the connecting base 53. The fixing ball 57 is installed inside the connecting base 53. The fixing ring 58 is fitted onto the outer wall of the connecting base 53.

[0021] It should be noted that the sampling head 3 described in this embodiment of the present invention is made of 316 stainless steel and is divided into a filter clip sampling head 3, an ultra-low particulate matter sampling head 3, and a flue gas sampling head 3, all of which are equipped with a pitot tube and a sampling head smoke temperature sensor. The sampling head 3 and the sampling tube 2, wherein the pitot tube conduit 66 is sealed with a heat-resistant O-ring, and the sampling head smoke temperature sensor signal line 65 and the sampling head heating power line 64 are connected by a quick-connect fitting.

[0022] Specifically, when it is necessary to change different sampling heads, the operator first pushes the connecting seat 53 to remove the fixing ring 58 from the outer wall of the connecting seat 53. At this time, due to its own elasticity, the spring 55 will push the locking block 54 to move inside the mounting seat 51 and the connecting seat 53, so that the locking block 54 moves out of the slot 52. At this time, the operator can easily remove the connecting seat 53 from the outside of the mounting seat 51, then remove the sampling head 3 from the other end of the sampling tube 2, replace it with a new sampling head 3, and then put the connecting seat 53 back on the outside of the mounting seat 51. At this time, the locking block 54 will once again lock into the slot 52 to fix the connecting seat 53. The operation is simple and convenient, greatly improving the operator's work efficiency. At the same time, the anti-slip block 56 increases the friction between the operator's hand and the connecting seat 53, preventing the operator from slipping when disassembling or installing the connecting seat 53, further improving the operator's work efficiency.

[0023] In one embodiment of this application, such as Figure 1 As shown, the sampling tube 2 is equipped with a sampling component 6 inside.

[0024] The sampling component 6 includes an air extraction pipe 61, a heat tracing pipe 62, a heat tracing pipe temperature sensor 63, a power cord 64, a smoke temperature sensor signal line 65, and a Pitot tube conduit 66.

[0025] The extraction tube 61 is installed inside the sampling tube 2, the heat tracing tube 62 is installed inside the extraction tube 61, the heat tracing tube temperature sensor 63 is installed inside the sampling tube 2, the power cord 64 is installed inside the sampling tube 2, and the Pitot tube conduit 66 is installed inside the sampling tube 2.

[0026] Specifically, the heat tracing pipe 62 ensures that the temperature of the flue gas remains constant during sampling, preventing the condensation of pollutants in the flue gas due to temperature drops, which would affect the accuracy of the sampling results. A temperature sensor on the heat tracing pipe 62 monitors its temperature in real time, ensuring stable operation. The power cord 64 provides power to the heat tracing pipe 62 and other electronic devices in the sampling assembly 6.

[0027] In one embodiment of this application, such as Figure 1 As shown, a connecting pipe 4 is installed at the bottom of the controller 1.

[0028] Understandably, the connection pipe 4 facilitates the operator in connecting the controller 1 to other devices or systems to transmit data or receive control commands.

[0029] In one embodiment of this application, such as Figure 1 As shown, a handle 7 is installed on the bottom wall of the connecting pipe 4.

[0030] Understandably, the handle 7 allows operators to easily hold and move the entire smoke (gas) sampling tube 2, increasing ease of use.

[0031] In one embodiment of this application, such as Figure 1 As shown, the outer wall of the grip 7 is fitted with anti-slip pads 8.

[0032] Understandably, the anti-slip pad 8 is designed to increase the friction between the operator's hand and the handle 7, preventing the operator from slipping when holding and moving the smoke (gas) sampling tube 2, thereby ensuring the safety of operation.

[0033] In one embodiment of this application, such as Figure 1 As shown, a positioning block 9 is fitted on the outer wall of the sampling tube 2.

[0034] Understandably, the positioning block 9 is designed to ensure the stability of the sampling tube 2 during fixing or installation, preventing sampling errors or equipment damage caused by the shaking of the sampling tube 2.

[0035] Working Principle: In practical applications, the operator first connects the multi-purpose dust or flue gas sampling tube 2 of this utility model to the corresponding testing equipment or system via the connecting pipe 4. Then, a suitable sampling head 3 is selected and installed according to the testing requirements. When installing the sampling head 3, the operator simply pushes the connecting seat 53, using the elastic force of the spring 55 to move the locking block 54 out of the slot 52, allowing for easy disassembly and replacement of the sampling head 3. The operation is simple and quick. After installing the sampling head 3, the operator holds the handle 7 and inserts the sampling tube 2 into the environment to be tested, starting the sampling program through the controller 1. At this time, the extraction pipe 61 in the sampling assembly 6 begins to work, drawing the dust (gas) to be tested into the sampling tube 2. The heat tracing pipe 62 maintains a constant temperature of the flue gas during sampling, preventing pollutant condensation and ensuring the accuracy of the sampling results. The heat tracing pipe temperature sensor 63 monitors the temperature of the heat tracing pipe 62 in real time, ensuring the stable operation of the heat tracing pipe 62.
