Embodiment Construction

[0019] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0020] See figure 1 , figure 1 It is a schematic diagram of an acid mist particle size detection device according to an embodiment of the present invention. The acid mist particle size detection device of the present invention is used to detect the acid mist in the gas in the tower body 20. The detection device includes a probe 1 connected in sequence, a connecting pipe 2, a tight sealing device, a gas washing bottle 5, a jet scrubber, Flow meter 7 and vacuum pump 9.

[0021] The probe 1 can be moved in the tower body 20 along the radial direction of the tower body 20. The probe 1 has a detection port 19 that can rotate around its own axis, and the detection port 19 goes deep into the tower body 20 through the sampling port of the tower body 20. internal. Preferab...

Abstract

The invention provides an acid mist particle size detection device and detection method, and is used for detecting acid mist in gas in a tower body. The detection device comprises a probe, a connecting pipe, a sealing device, a gas-washing bottle, an injection washer, a flowmeter and a vacuum pump which are connected in sequence; the connecting pipe is used for regulating the depth of probe in thetower body; the sealing device is arranged on the sampling hole of the tower body and is used for sealing; the gas-washing bottle is arranged out of the tower body; the flowmeter is used for regulating gas flow; the vacuum pump is used for providing airflow power in the air pipeline of the detection device; the air inlet of the gas-washing bottle is communicated with the probe through the connecting pipe, and the air outlet is communicated with the injection washer; the injection washer comprises multilevel knocking samplers which are connected in sequence for collecting mist particles of different diameters, and a glass fiber filter used for removing residual tiny mist particles in gas; the flowmeter is connected between the glass fiber filter and the vacuum pump. According to the acid mist particle size detection device, acid mist content in gas can be detected, and acid mist particle sizes in the gas can be analyzed.

Description

technical field [0001] The invention relates to the field of acid mist detection, in particular to an acid mist particle size detection device and detection method. Background technique [0002] Acid mist usually refers to misty acid substances. The particles of acid mist in the air are very small, smaller than those of water mist, and higher in humidity than smoke, with a particle size of 0.1-10 μm, which is highly corrosive. Acid mist is mainly produced in the process of using acid in chemical, electronic, metallurgy, electroplating, textile, machinery manufacturing and other industries. [0003] As the country's environmental protection requirements become increasingly strict, especially the sulfuric acid industry, the requirements for the export of acid mist are also getting higher and higher, and some areas even require less than 20mg / m3, so good and accurate acid mist detection methods are particularly important. It can ensure the normal operation of the entire syste...
