Description

Technical Field

[0001] This utility model relates to the field of acid mist sampling technology, and in particular to an acid mist sampling device. Background Technology

[0002] Acid mist refers to a mist-like substance of acidic substances, typically formed from inorganic acids such as sulfuric acid, nitric acid, and hydrochloric acid, and organic acids such as formic acid, acetic acid, and propionic acid. Acid mist particles are small, ranging in size from 0.1 to 10 micrometers, and are highly corrosive. Acid mist is mainly formed from sulfur-containing oxide emissions during processes such as fossil fuel combustion, mineral smelting, or sulfuric acid production. These emissions condense into tiny acid mist particles in the air, posing a threat to the environment and human health.

[0003] A search revealed that patent CN218271576U discloses a sampler for detecting acid mist in exhaust gas. This sampler uses a negative pressure fan to draw exhaust gas into its casing, while the acid mist enters the sampling tube and is absorbed by an absorbent liquid inside for subsequent detection. However, during use, the acid mist, after being drawn into the casing, only comes into contact with the absorbent liquid on the surface of the sampling tube, resulting in low collection efficiency. Secondly, the device is relatively large, making it inconvenient to carry and use. Furthermore, it can only be used in one fixed location, limiting its acid mist collection range. Therefore, further improvements are needed. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an acid mist sampling device, comprising a main housing, an air pump fixedly installed inside the main housing, and an air pump inlet and outlet fixedly connected to an air extraction pipe and an air exhaust pipe, respectively; the other end of the air extraction pipe is located outside the main housing and is fixedly connected to a flexible hose; the other end of the flexible hose is fixedly connected to a sampling hood; a telescopic component is fixedly connected to the outer wall of the sampling hood; a sample storage component is fixedly connected to the end of the exhaust pipe located outside the main housing; a control button is provided on the outer surface of the main housing and is electrically connected to the air pump; and a maintenance cover is fixedly connected to the bottom side wall of the main housing by bolts.

[0006] Furthermore, the sample storage assembly includes a sample storage tube, a bent tube is fixedly connected through the side wall of the sample storage tube, one end of the bent tube located outside the sample storage tube is slidably sleeved on the surface of the vent pipe, the sample storage tube stores absorbent liquid inside, and a vent hole is opened on the side wall at the top of the sample storage tube.

[0007] Furthermore, the outer wall of the top end of the sample storage tube is threaded, and a top cover is rotatably connected to the threaded surface. An end cap is provided to match the bend, and the end cap can be sleeved onto the surface of the bend through friction.

[0008] Furthermore, an arc-shaped retainer for inserting the sample storage tube is fixed to the outer wall of the main housing.

A control button 8 is provided on the outer surface of the main housing 1 and is electrically connected to the air pump 2. An inspection cover 12 is fixedly connected to the bottom side wall of the main housing 1 by bolts.

[0023] The sample storage assembly 6 includes a sample storage tube 61, a bent tube 62 is fixedly connected through the side wall of the sample storage tube 61, one end of the bent tube 62 located outside the sample storage tube 61 is slidably sleeved on the surface of the vent pipe 22, the sample storage tube 61 stores absorbent liquid inside, and a vent hole 63 is opened on the top side wall of the sample storage tube 61.

[0024] After the air pump 2 is started by the control button 8, the sampling hood 4 draws in the acid mist. The acid mist enters the sample storage tube 61 through the hose 3, the suction pipe 21, the exhaust pipe 22 and the bend 62. The acid mist is absorbed by the absorbent liquid inside the sample storage tube 61. Then the air that has absorbed the acid mist is discharged from the exhaust port 63.

[0025] The outer wall of the top end of the sample storage tube 61 is threaded, and a top cover 64 is rotatably connected to the threaded surface. An end cap 65 is provided to match the bent tube 62. The end cap 65 can be sleeved on the surface of the bent tube 62 by friction.

[0026] After the sample storage tube 61 has finished absorbing the acid mist, the bent tube 62 can be removed from the surface of the exhaust pipe 22. Then, the end cap 65 is placed on the surface of the exhaust pipe 22, and the top cover 64 is screwed down along the sample storage tube 61 to block the exhaust hole 63, thereby sealing the inside of the sample storage tube 61.

[0027] An arc-shaped retainer 7 for inserting the sample storage tube 61 is fixed on the outer wall of the main housing 1.

[0028] When in use, the sample storage tube 61 can be clipped into the arc-shaped holder 7 to further secure the sample storage tube 61.

[0029] An electronic timer 9 is fixedly installed on the upper surface of the main housing 1.

[0030] The sampling time can be timed using the electronic timer 9.

When in use, hold the handle 51 and extend the sampling hood 4 to the designated position to suck up the acid mist.

[0035] Working principle: Take out a sample storage component 6 and fit the bent tube 62 of the sample storage tube 61 onto the surface of the exhaust pipe 22. At the same time, insert the sample storage tube 61 into the arc-shaped bracket 7. Then, hold the handle 51 with one hand and extend the sampling hood 4 to the designated position. Next, turn on the air pump 2 and the electronic timer 9 with the other hand. Acid mist enters the sample storage tube 61 through the hose 3, the suction pipe 21, the exhaust pipe 22, and the bent tube 62. The acid mist is absorbed by the absorbent liquid inside the sample storage tube 61. Then, the air that has absorbed the acid mist is discharged from the exhaust port 63. After sampling, remove the bent tube 62 from the surface of the exhaust pipe 22 and replace it with another sample storage component 6 to continue sampling.
