Embodiment 1

[0019] The embodiment is basically as attached figure 1 Shown: A detection device for sulfur dust in a sulfur production workshop, including a cylinder body 1. A frame is nailed to the inner wall of the sulfur production workshop. The cylinder body 1 is located on the frame body. Mouths are equal in height. The cylinder body 1 is filled with 0.1mol / L sodium hydroxide solution (ph value is 13), in order to prevent the sodium hydroxide from corroding the cylinder body 1, the cylinder body 1 is made of PPS plastic. The cylinder body 1 is provided with a drain port 2 , a drain pipe 3 , a spring sealing plug 4 and a pH sensor 5 . The drain port 2 is located at the bottom of the cylinder body 1 , and the drain pipe 3 communicates with the drain port 2 . The spring sealing plug 4 is connected with the liquid discharge port 2 (press the spring sealing plug 4 to pop up, and the liquid can be discharged from between the liquid discharge port 2 and the spring sealing plug 4; press the ...

Embodiment 2

[0025] Such as figure 2 As shown, the difference between this embodiment and embodiment 1 is that the pH sensor 5 is not used, but phenolphthalein solution is added to the 0.1 mol / L sodium hydroxide solution. Phenolphthalein is colorless in acidic and neutral solutions, and purple in alkaline solutions. The solution in cylinder 1 can be judged by the color change.

[0026] Although the indication of the pH value is not very accurate in this embodiment (if necessary, a pH test paper can be provided), the pH sensor 5 is not used, and the cost is relatively low and intuitive.

Abstract

The invention discloses a sulphur dust detection device for a sulphur production workshop. The sulphur dust detection device comprises a cylinder body connected to an inner wall of a sulphur production workshop, a sodium hydroxide solution is arranged in the cylinder body, the cylinder body is provided with a liquid outlet, a liquid outlet pipe, a sealing plug and a pH sensor, the liquid outlet is located at the bottom of the cylinder body, the liquid outlet is communicated with the liquid outlet pipe, the sealing plug is movably connected to the liquid outlet, an operation rod is connected to the sealing plug, the operation rod is higher than the level of the sodium hydroxide solution, and a detection head of the pH sensor is located in the sodium hydroxide solution. The pH sensor can detect a change rate of pH of the sodium hydroxide solution in the cylinder body and is convenient for determining if a concentration of sulphur dust suspension particles in a sulphur production workshop exceeds the standard. The sulphur dust detection device can be used for detecting sulphur dust suspension particles in a sulphur production workshop, does not detect all dust suspension particles and satisfies detection requirements on dust in a sulphur production workshop.

Description

technical field [0001] The invention relates to the technical field of measuring the concentration of suspended particles, in particular to the measurement of the concentration of dust suspended particles in a sulfur production workshop. Background technique [0002] Sulfur, also known as sulfur, colloidal sulfur, or sulfur block, is a yellow solid or powder with a distinct odor and is insoluble in water. As a flammable solid, sulfur is mainly used in the manufacture of dyes, pesticides, matches, gunpowder, rubber, rayon, etc. Sulfur powder mixed with air or oxidant is prone to combustion and even explosion. [0003] Therefore, the sulfur production workshop needs to strictly control the concentration of sulfur powder suspended particles. The first thing that needs to be done is to detect the sulfur dust in the sulfur production workshop. In the production of sulfur, sulfur ore is used as raw material, and various types of dust will be produced. In addition to sulfur dust,...
