Abstract
The invention discloses a method for analyzing and detecting the waste emissions of a cement plant. The method comprises the following steps: extracting a certain volume of waste gas emissions from an outlet of a discharge pipeline of the cement plant by an appliance, and trapping the particulate matters in the waste gas emissions by a filter cartridge; putting the particulate matters onto a microscope, and selecting the particulate matters with the maximum particle sizes to obtain the particle sizes of the particulate matters; filling the waste gas in the appliance into a non-dispersive infrared analyzer to obtain the types and the contents of gases in the waste gas by utilizing the principle that the infrared rays with different wave lengths are absorbed by the different gases. After the method for analyzing and detecting the waste emissions of the cement plant is adopted, on one hand, the particle sizes of the emissions can be analyzed and detected, so that a proper filter film can be selected, and on the other hand, the contents of all the components in the discharged waste gas can be analyzed and detected, so that right amount of reagent can be selected for the absorption reaction; the detection method is capable of finding a proper waste gas emission treatment method, is rapid, simple and low in cost, and can be applied on a large scale.
Description
Technical field
The present invention relates to emission detection field, particularly relate to a kind of cement mill waste emissions analyzing detecting method.
Background technology
Along with the development of city and country, the mankind to a large amount of developments and utilizations of resource simultaneously, also a large amount of various pollutants are discharged continuous to nature, when the content of these pollutants exceedes natural self purification, direct harmful effect and harm will be produced, atmospheric pollution that Here it is to human body, animals and plants.The three large key elements forming atmospheric pollution are: pollution source, air medium and contaminated acceptor, pollution source are the formation from objectionable impurities to environment and the equipment that enter, therefore, the character of degree and the pollutant of atmospheric pollution, the discharge of pollution source, meteorological condition and geographical conditions etc. are relevant.In the cement production process of cement mill, a large amount of dust and waste gas can be produced, these dust and waste gas can cause serious pollution to the environment that we survive, need to touch the mark and could discharge, therefore need to cement mill discharge dust and waste gas carry out analysiss detection, to select corresponding disposal route.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of cement mill waste emissions analyzing detecting method, and this detection method is simple and quick and cost is low.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of cement mill waste emissions analyzing detecting method, comprising step is:
(1) extract the exhaust emissions of certain volume from delivery pipe road junction, cement mill with utensil, by filter cylinder, the particle in trap exhaust emission;
(2) described particle is placed on microscope, chooses the described particle that particle diameter is maximum, obtain the particle diameter of particle;
(3) waste gas in utensil is passed in NDIR, utilize gas with various to absorb ultrared wavelength different, obtain kind and the content of gas in waste gas.
In a preferred embodiment of the present invention, utensil described in step (1) is the syringe with syringe needle.
In a preferred embodiment of the present invention, will test in triplicate above, obtain the mean value of each component concentration in particle size and waste gas.
The invention has the beneficial effects as follows: cement mill of the present invention waste emissions analyzing detecting method, the particle size detecting emission can either be analyzed, choose suitable filtering membrane, the content of each component in the waste gas detecting discharge can be analyzed again, choose appropriate reagent and carry out absorption reaction, this detection method can find suitable toxic emission substance treating method, fast simply, cost is low, can apply on a large scale.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
There is provided a kind of cement mill waste emissions analyzing detecting method, comprising step is:
(1) extract the exhaust emissions of certain volume from delivery pipe road junction, cement mill with utensil, by filter cylinder, the particle in trap exhaust emission, described utensil is the syringe with syringe needle;
(2) described particle is placed on microscope, chooses the described particle that particle diameter is maximum, obtain the particle diameter of particle;
(3) waste gas in utensil is passed in NDIR, utilize gas with various to absorb ultrared wavelength different, obtain kind and the content of gas in waste gas;
(4) will test in triplicate above, obtain the mean value of each component concentration in particle size and waste gas.
The invention has the beneficial effects as follows:
One, described cement mill waste emissions analyzing detecting method can analyze the particle size detecting emission, chooses suitable filtering membrane;
Two, described cement mill waste emissions analyzing detecting method can analyze the content of each component in the waste gas detecting discharge, chooses appropriate reagent and carries out absorption reaction;
Three, described cement mill waste emissions analyzing detecting method can find suitable toxic emission substance treating method, and fast simply, cost is low, can apply on a large scale.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
