As shown in fig. 1, the anti-blocking gas detector according to the embodiment of the present application includes: the gas purification and filtration device comprises a detector body 1 and a gas purification and filtration device 10, wherein the gas purification and filtration device 10 is arranged at the end part of a detection port of the detector body 1 and used for blocking dust or corrosive particles from entering the detector body. The gas purification and filtration device 10 is arranged at the end part of the detection port and used for preventing dust or corrosive particles from entering the detector body.

From the above description, it can be seen that the following technical effects are achieved by the present application:

in this application embodiment, adopt detector body, gaseous purification filter equipment, the detection mouth tip of detector body is provided with gaseous purification filter equipment for separation dust or corrosive particles get into the mode of detector body through gaseous purification filter equipment, has reached and has prevented or reduce the direct inside purpose that gets into the sensor of dust or granule to realized the technological effect of extension detector life-span, and then solved the lower and generally not high technical problem of life of gas detector measurement accuracy.

According to the embodiment of the present application, as a preference in the embodiment, the gas purification filter device 10 is filled with a filter medium material.

According to an embodiment of the present application, as a preference in the embodiment, the filter medium material includes: any one or more of glass fiber, polypropylene fiber, polyester fiber or plant fiber.

Specifically, a gas saving body purification and filtration device is additionally arranged at the detection front end of the sensor. The adhesion force of dust and a filter medium is that dust particles in air move along with the air flow in an inertial motion mode, or move irregularly, or move under the action of a certain field force, and when the moving particles collide with an obstacle, van der Waals force between the particles and the obstacle causes the particles and the obstacle to be adhered together. The filter media material should be effective in intercepting dust particles without creating excessive resistance to airflow. The randomly interwoven fibers form numerous barriers to particles, and the wide spaces between fibers allow airflow to pass through smoothly.

According to the embodiment of the present application, as a preference in the embodiment, the gas purification filter device 10 is filled with an electrostatic filter material. Static electricity causes the dust to change its motion trajectory and hit obstacles.

According to the embodiment of the present application, it is preferable that the gas cleaning filter device 10 is used for filtering the small particle dust in brownian motion in the air.

The small particle dust makes random Brownian motion, the smaller the dust is, the more violent the random motion is, the more chance of impacting the barrier is, and therefore, the better the filtering effect is. Small particle dust in the air mainly makes Brownian motion, and the smaller the particles are, the higher the efficiency of the filter is; the larger the particles, the higher the efficiency of the filter.

According to the embodiment of the present application, it is preferable that the gas purifying and filtering apparatus 10 is used for filtering large particles moving inertially in air.

In particular, common filtration mechanisms are classified into an inertial principle, a diffusion principle, and an electrostatic force. The large particle dust is subjected to inertial motion in the air flow. The air current detours with the obstacle, and the dust deviates from the air current direction due to inertia and collides with the obstacle. The larger the particles, the stronger the inertial force, the greater the possibility of hitting an obstacle, and therefore the better the filtering effect.

At the same time, the efficiency values at low points are most representative. If the filter material or the dust is electrostatically charged, the filtering effect can be significantly improved. The reasons for this are mainly two: static electricity causes the dust to change the motion track and collide with the barrier; electrostatic forces cause the dust to stick more firmly to the media. The dust trapped by the filter resistance creates additional resistance to the airflow and the resistance of the filter will gradually increase during use. The captured dust integrates with the filter media to form an additional barrier so that the filter efficiency is also improved in use. Most of the captured dust is collected on the windward side of the filter material. The larger the area of the filter material is, the more dust can be contained, and the longer the service life of the filter is. The more dust deposited on the filter material, the greater the resistance. When the resistance is unreasonably high, the filter element is rejected. In some cases, the filter element is scrapped when there is a risk that dust captured on the filter is scattered due to excessive resistance. The resistance of the filter is improved along with the increase of the air flow, and the relative wind speed passing through the filter material can be reduced by increasing the area of the filter material so as to reduce the resistance of the filter.

According to the embodiment of the present application, as a preferred feature of the embodiment, as shown in fig. 1, the probe body is fixedly connected to the gas purifying and filtering device 10.

Specifically, the probe body and the gas purification and filtration device 10 are fixedly connected, and may be connected by a snap fit.

According to the embodiment of the present application, as shown in fig. 1, it is preferable that the probe body and the gas purification and filtration device 10 are connected in a split manner.

The detector body and the gas purification and filtration device 10 are connected in a split mode, and are convenient to detach and replace in a split mode.

According to the embodiment of the present application, as shown in fig. 2, it is preferable that the probe body and the gas purifying and filtering device 10 are integrally formed.

The gas purification and filtration device 10 is sleeved with the detector body 1 and is integrally formed, so that the gas purification and filtration device is suitable for scenes with high filtration requirements. The gas purification and filtration device 10 can be replaced by replacing the filter medium material filled in the device.

According to the embodiment of the present application, as shown in fig. 3, preferably, the probe body is sleeved with the gas purification and filtration device 10.

The gas purification and filtration device 10 effectively prevents dust or corrosive particles from entering the sensor by adopting sleeve joint, ensures the measurement precision and greatly prolongs the service life, and the dust filtration device is applied to the gas detector.

Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
