Description
Technical field
The invention belongs to Environmental Safety facility technology field, be specifically related to a kind of dust atmosphere analogue means, for dust concentration sampling thief provides the comparison data of standard.
Background technology
As is known in the industry; those are easily produced in production operation process to the industry of dust; such as colliery, manufacture of cement industry, textile industry, food-processing industry (flour mill) and chemical and medicine industry industry etc.; usually need to rely on dust concentration sampling thief (also to claim dust concentration detector; as follows) dust concentration of swimming in the air of Work places is monitored; to take corresponding Disposal Measures; on the one hand protection occupational population is healthy, prevents from the other hand exceeding standard because of dust concentration and meeting electrostatic or naked light sets off an explosion.Exploded by the flour mill of media report in the past, numb cotton mill exploded, metal product plant polishing departement explodes, and (as especially big aluminum dust explosion accident that Jiangsu Province, China city of Kunshan Zhong Rong metallic article company limited occurs) etc. was all tending towards saturated because of the dust concentration of swimming in air and met caused by electrostatic or naked light.In addition, the occupational illness of the worker of above-mentioned industry is as also general because of caused by the long-term dust by Work places encroaches in silicosis (pneumoconiosis).Along with people to carrying out production strictly in line with rules and regulations, the significantly improving of cleaning operation and safe construction and people-based concept, the system of operation field being carried out to dust monitoring is not only formulated for being not limited to the aforementioned industry exemplified, and for operation field or claim the workman in a line post to be equipped with the dust concentration sampling thief of various version (as being similar to the sampling head of CN2800261Y structure) or corresponding instrument (as being similar to the Bidirectional diaphragm pump of CN2799901Y structure), this is comparatively general in colliery.In addition, the supervision instrument of dust concentration sampling thief Ye Shi environmental administration, safety supervision department etc.
Complete dust concentration sampling thief is made up of signal transmitter structure, signal receiving structure, signal processing mechanism, dust sampling head and membrane pump (also claiming extraction sector) etc. usually, and can be seen in disclosed Chinese patent literature, " direct-reading dust concentration measuring instrument " that " direct-reading dust concentration detector " and CN102419296B typically as invention patent mandate notification number CN102221519B recommendation recommend, etc.
The dust concentration sampling thief of the comparison data with standard is called standard dust concentration sample device by industry custom, and the dust concentration sampling thief being used for carrying out dust scene dust concentration sampling is called common flour dust concentration sampling thief, the field data that the former normal data and the latter obtain compared, whether the dust concentration just can understood in test environment exceeds standard.But, to make standard dust concentration sample device obtain standard compliant dust concentration data, then usually rely on artificial dust atmosphere analogue means to realize, and dust atmosphere analogue means also contribute to the development of dust detection technique and dust control technology.
