Description

Technical Field

[0001] The utility model relates to the technical field of gas analysis, in particular to a dustproof gas analysis instrument. Background Art

[0002] A gas analyzer is a device used to measure gas composition. It is widely used in the field of gas analysis technology. In many production processes, especially those involving chemical reactions, automatic control based solely on physical parameters such as temperature, pressure, and flow is often not enough, and gas analyzers are needed for auxiliary control. Commonly used gas analyzers include thermal conductivity, electrochemical, and infrared absorption.

[0003] When the gas analyzer in the prior art is in use, the gas content in a set area or container is analyzed through a sensor. However, since the air in the area may contain some dust particles, the detection end of the device is easily covered with dust particles after operating for a period of time, which reduces the accuracy of the device's detection structure and thus affects the practicability of the device.

[0004] Based on this, the utility model designs a dustproof gas analysis instrument to solve the above problems. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a dustproof gas analysis instrument, which has the following beneficial effects:

[0016] 1. The dust-proof gas analyzer uses a filter assembly to allow a circulating fan to drive external air into the dust filter tube through the second air duct and the front expansion cover. The air in the dust filter tube enters the rear expansion cover through the dust filter net tube under pressure. In this process, dust particles in the air are filtered and separated by the dust filter net tube. The filtered air enters the analysis body through the analysis air inlet hole for detection, which reduces the number of dust particles in the air entering the analysis body, improves the accuracy of the device detection structure, and thus enhances the practicability of the device.

[0017] 2. The dust-proof gas analyzer has two groups of inlet pipes arranged in a staggered manner, so that the filtered air input by the filter assembly is evenly filled into the cover. The air in the cover enters the analysis body through the analysis air inlet hole for detection, which effectively improves the balance of the air entering the analysis body through the analysis air inlet hole. At the same time, the exhaust hole is used to output the excess air in the cover, which greatly reduces the probability of damage to the analysis body caused by the pressurized air entering the analysis body, thereby enhancing the applicability of the device.

[0018] 3. The dust-proof gas analyzer operates in reverse through the circulating fan to allow external air to enter the enveloping cover through the exhaust hole. The air in the enveloping cover enters the dust filter tube through the air inlet pipe, the first air duct and the rear expansion cover under pressure. The air in the dust filter tube enters the front expansion cover through the dust filter mesh cylinder. During this process, the dust particles in the dust filter mesh cylinder are stripped off by the air, and the air in the front expansion cover drives the dust particles to be discharged from the front end of the circulating fan through the second air duct, thereby improving the convenience of cleaning dust accumulated in the device.
