Problems solved by technology

The sampling device uses water to directly cool the smoke and dust. Although the cooling speed is fast, the smoke and dust are collected when the smoke flows through the water curtain naturally, and the collection efficiency is low. Secondly, the water curtain is formed by gravity, and the sampling device must be placed vertically for sampling, and the sampling location is set Large limitations; at the same time, water is in direct contact with the soot sample, so it is not suitable for sampling of soot containing water-soluble components

Embodiment Construction

[0008] Such as figure 1 As shown, a high-temperature smoke and dust online sampling device includes a sampling tube 1, one end of the sampling tube 1 is connected to the air inlet of the cyclone 2, the gas outlet of the cyclone 2 is connected to an outlet pipe 3, and the gas outlet of the cyclone 2 is connected to the air outlet of the cyclone 2. The bottom is threadedly connected with a collection tank 4 , the furnace gas enters the cyclone 2 from the sampling pipe 1 , the smoke and dust separated by the cyclone 2 falls into the collection tank 4 , and the flue gas is discharged through the outlet pipe 3 . Furnace gas enters through the sampling pipe 1 from one side of the cyclone 2 along the tangential direction. Under the strong swirl force, the soot particles in the flue gas are collected and enter the soot collection tank 4, while the flue gas flows from the outlet The air pipe 3 is discharged, and the dust collection speed is fast and the efficiency is high; in the prese...

Abstract

The invention aims to provide an online sampling device for high-temperature smoke dust. The online sampling device is high in complementing efficiency and high in sampling precision, and comprises asampling pipe, wherein one end of the sampling pipe is connected with a gas inlet of a cyclone, a gas outlet of the cyclone is connected with a gas outlet pipe, the bottom part of the cyclone is in threaded connection with a collecting tank, a furnace gas enters the cyclone from the sampling pipe, smoke dust separated by means of the cyclone falls into the collecting tank, and smoke is dischargedby means of the gas outlet pipe. According to the online sampling device, the cyclone is arranged to increase the intensity of complementing the smoke dust in the furnace gas, the smoke dust catchingspeed is high, the smoke dust catching efficiency is high, and therefore subsequent chemical component analysis and particle size screening results are more real and reliable.

Description

technical field [0001] The invention relates to the field of smoke and dust detection, in particular to an online sampling device for high-temperature smoke and dust. Background technique [0002] During the production process of metallurgical furnaces, a large amount of furnace gas mixed with smoke and dust will be generated. The accurate determination of the chemical composition and phase of the smoke in the furnace of the metallurgical furnace and the subsequent dust collection system is very important for the analysis and regulation of the reaction process of the metallurgical furnace, the cooling process of the flue gas, and the furnace It is of great significance for internal and flue bonding, furnace equipment design, etc. However, the sampling of smoke and dust in metallurgical furnaces and dust collection systems faces several difficulties: (1) The temperature of flue gas and dust is high, generally at 300-1600°C, which requires the sampling device to have high temp...
