Smoke generation system for calibrating accuracy of low concentration particle test method

Abstract

The invention discloses a smoke generation system for calibrating accuracy of a low concentration particle test method. The smoke generation system comprises a simulation smoke flue, a dust feed device for feeding dust to the simulation smoke flue, an air supply device for supplying air to the simulation smoke flue, a humidification device for supplying steam to the simulation smoke flue, an acidadding device for supplying mixed acid to the simulation smoke flue, and a heating device for supplying heat to the simulation smoke flue, wherein the wall surface of the simulation smoke flue is provided with test holes, and parameters of smoke in the simulation smoke flue are detected by using the test holes. The smoke generation system can effectively save the cost of the low concentration particle test method and shorten the development cycle of the low concentration particle test method. Moreover, the dust feed device comprises a feed rod, a sleeve sheathed on the feed rod, and a first drive part driving the feed rod to rotate, the sleeve has an end plane vertical to the axis of the sleeve, one end of the feed rod is provided with a smooth rod and the other part is provided with a threaded rod, the end surface of the smooth rod is flush with the end plane of the sleeve, and the dust feed device can feed dust uniformly.

Description

technical field [0001] The invention relates to the technical field of low-concentration particulate matter testing in coal-fired power plants, in particular to a flue gas generation system for calibrating the accuracy of a low-concentration particulate matter testing method. Background technique [0002] In recent years, coal-fired power plants have been gradually improved in the direction of environmental protection, cleanliness and energy saving. There are increasingly higher standards for flue gas emissions, and how to achieve "ultra-clean emissions" has become a research hotspot. [0003] In the process of ultra-clean emission research, a difficult point is involved: how to improve the accuracy of low-concentration particulate matter testing. Now the test is carried out according to the current national standard method, and there are often problems such as sample weight loss, condensed water sucking back, sample damage, poor parallelism and sample weighing drift, which...

Problems solved by technology

[0005] In the prior art, the usual way to detect the accuracy of the low-concentration particle test method is on-site detection, which is not only inconvenient to implement, but also has a long detection cycle, which makes the development cycle of the low-concentration particle test method longer and consumes higher manpower and material costs.
