Purifying and detecting method of carbon black smoke and device thereof

Abstract

The invention relates to a purifying and detecting method of carbon black smoke and a device thereof. The device comprises a buffer section, a dust removal section, a cooling section and a drying section. The method comprises the following steps: high-temperature and high-speed carbon black smoke passes the buffer section to lead the flow speed thereof to reduce to a preset value, the carbon black smoke sequentially passes the dust removal section to remove carbon black dust contained, subsequently the carbon black smoke passes the cooling section to lead the temperature thereof to reduce to a temperature below a room temperature, then the cooled carbon black smoke passes the drying section to remove water contained, and finally the dried carbon black smoke is conveyed into detecting equipment for analysis and testing. The method has simple technique, convenient operation, high purifying and testing efficiency, and accurate testing result and simultaneously the device has simple and compact structure, small volume, easy installation and maintenance and low cost. The application of the invention can detect the contents of flammable gas ingredients contained in the carbon black smoke in time and accurately, thus preventing the occurrence of a dangerous situation and effectively reducing the production cost of carbon black production factories.

Description

technical field [0001] The invention specifically relates to a carbon black flue gas purification detection method and device in the technical field of carbon black manufacture. Background technique [0002] The carbon black flue gas produced in the existing carbon black production process usually contains a variety of flammable gas components, and these components often reach the explosion limit due to the intervention of air during the collection, separation and transportation of the production device. Under the conditions of igniting factors such as open flames, it is very easy to cause serious damage to the carbon black production line and endanger the life safety of the staff. In order to eliminate the danger, the means we can adopt are mainly to effectively monitor the various links through which the carbon black smoke passes, so as to eliminate the necessary conditions that can cause the explosion of flammable gases in time. Combining the statistical results of safet...

Problems solved by technology

[0003] At present, there are mainly two methods for detecting carbon black smoke, one of which is to install a sampling port at a designated section of the carbon black production line, and use a balloon to take out the carbon black smoke at the sampling port regularly or irregularly The disadvantage of this method is that the carbon black smoke sample contains a large amount of carbon black dust and water vapor, which is easy to contaminate the gas chromatography and other test equipment, making the analytical instrument unable to work normally or the test data inaccurate. One method is to install on-line detection equipment at the designated position of the carbon black production line, but this method also has disadvantages. First, the detection port of the on-line detector is easy to deposit carbon black powder, which is not easy to clean, which often causes the detection equipment to fail to operate normally. Such testing equipment is generally bulky, expensive, and inconvenient to install and maintain, thus greatly increasing the production cost of carbon black manufacturers
