Description

Technical Field

[0001] The invention relates to the technical field of gas detection, and in particular to a micro gas collection structure for pyrolysis ions. Background Art

[0002] Pyrolytic particles, also known as "pyrolytic ions", are produced when a substance is damaged by heat. In this process, the atoms inside the substance gain additional energy, causing their outer electrons to escape, which triggers ionization and releases charged pyrolytic ions. A detection system specifically designed to identify overheating of equipment at a very early stage relies on the detection of these pyrolytic ions. In order to improve the accuracy of detection, the system must be able to accurately identify and measure pyrolytic ions. The prerequisite for achieving this precise detection is that the gas collection structure must have efficient and stable performance.

[0003] The micro gas collection structure for pyrolysis ions is a device that can efficiently capture and concentrate tiny gas molecules. It is widely used in gas detection and analysis systems to absorb and collect trace gases escaping from various sources to improve the sensitivity and accuracy of detection equipment. The micro gas collection structure for pyrolysis ions plays an important role in environmental monitoring, medical diagnosis, and industrial process control.

[0004] However, the traditional gas collection structure for pyrolysis ions has the problems of large size, complex manufacturing process and high cost. In applications such as portable gas detectors and micro chemical sensors, a gas collector with a smaller size, simplified manufacturing process and lower cost is needed.

[0005] To this end, we propose a micro gas collection structure for thermally released ions. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the present invention provides a micro gas collection structure for pyrolytic ions.

[0007] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0008] A micro gas collection structure for thermally released ions comprises: an air intake section, which is in the shape of a trumpet with openings at both ends and an air guide assembly arranged on the inner wall; an air delivery section, which is in the shape of a cylinder and has its bottom end connected to the small-diameter opening at the top of the air intake section, the inner diameter of the air delivery section matches the inner diameter of the small-diameter opening of the air intake section, and the top of the air delivery section is connected to a collection device; and a flow guide, which is arranged in the air intake section and guides the hot air entering the air intake section so that it can smoothly enter the air delivery section.

[0009] By providing an air intake section and an air delivery section provided on the top of the air intake section, high-temperature gas is taken in from the large-diameter opening at the bottom of the air intake section. The gas entering the air intake section can be effectively sucked in and guided into the air delivery section through the air inlet assembly on the inner wall of the air intake section. The inner diameter of the air delivery section matches the inner diameter of the small-diameter opening of the air intake section, which facilitates the smooth passage of gas. The guide piece provided in the air intake section can speed up the passage of gas and improve the collection efficiency. While ensuring the collection effect, the structure is simpler and the manufacturing cost is lower.

[0010] It is further defined that the air induced component is an exhaust fan, and a plurality of exhaust fans are provided, and the plurality of exhaust fans are evenly spaced on the inner wall of the air intake section, and the ventilation direction of the exhaust fans is parallel to the inclination direction of the inner wall of the air intake section; arranging the exhaust fans as the air induced component is conducive to the gas being effectively sucked in and guided into the air supply section.

[0011] It is further defined that a plurality of air supply fans are provided in the air supply section, the air outlet direction of the air supply fans is the top direction of the air supply section, and the plurality of air supply fans are arranged in parallel and at intervals in the air supply section; by arranging a plurality of air supply fans in an overlapping manner, the air supply efficiency can be increased, which helps to form a stronger airflow in the air supply section and promotes the rapid flow of gas.

[0012] It is further defined that the guide member includes a mounting rod and guide blades, and a plurality of guide blades are provided. The plurality of guide blades are relatively arranged on the circumferential surface of the mounting rod, and the relative guide blades are staggered. By arranging guide blades on both sides of the mounting rod, the gas can be guided to flow upward in a vertical direction into the air supply section, thereby increasing the gas flow rate in the system and improving the collection efficiency.

[0013] It is further defined that a horizontal mounting frame is fixedly provided on the top of the mounting rod, the mounting frame is in a cross shape, the four ends of the mounting frame are fixedly provided at the connection between the air supply section and the air intake section, and the axis of the mounting rod coincides with the axis of the air supply section; the mounting rod is installed by means of the cross-shaped mounting frame, the structure is simple, and the installation is convenient.

[0014] It is further defined that the horizontal width of the guide vanes on both sides of the mounting rod matches the inner diameter of the small-diameter opening of the air inlet section; setting the horizontal width of the guide vanes in this way can enhance the guiding effect on the gas.

[0015] It is further defined that the inner wall of the air supply section is coated with an inorganic ceramic nano-coating; such provision of the inorganic ceramic nano-coating can improve the high temperature resistance and dust filtering efficiency of the air supply section, and improve the purity of the collected gas.

[0016] It is further defined that the angle between the inclined surface of the air intake section and the vertical line is 35°-45°.

[0017] It is further defined that the vertical height ratio of the air intake section and the air delivery section is 7:2.

[0018] The beneficial effects of the present invention are as follows: by setting an air intake section and an air supply section, through the air inlet section, the air supply fan in the air supply section, and the flow guide in the air intake section, the gas flow rate can be increased, thereby improving the gas collection efficiency, and the structure is simple and easy to use.
