Abstract

The invention provides a method for measuring and calculating a sludge calorific value based on sludge volatile component content. The method comprises the steps of: calculating volatile components ofvarious samples and calorific values corresponding to the volatile components; establishing an XY plane rectangular coordinate system; determining each point corresponding to each sludge sample in the XY plane rectangular coordinate system by taking a volatile component ((A%) as a value of an X coordinate and a calorific value (Q) as a value of a Y coordinate; and sequentially fitting and connecting the points into a curve from low to high according to the volatile components, so as to obtain a sludge volatile component-calorific value curve (A%-Q). For any kind of to-be-detected sludge, as long as the volatile component A to-be-detected% of the sludge is calculated firstly and the A to-be-detected% is substituted into the X axis according to the obtained sludge volatile component-calorific value curve (A%-Q), a corresponding calorific value Q (namely the value of the Y coordinate) can be directly found in the curve. The method can effectively solve the problems of high cost, high workload intensity, high requirements on the operation proficiency of technicians and the like caused by measuring the calorific value of the sludge by adopting a calorific capacity method in the prior art.

Description

technical field [0001] The invention relates to a method for testing the calorific value of sludge, in particular to a method for measuring and calculating the calorific value of sludge based on the volatile content of sludge. Background technique [0002] Sludge is a kind of solid waste that has great harm to human body and environment, and the environmental problems caused by the massive increase of sludge production are becoming more and more prominent. Since sludge contains a large amount of water and organic substances, it is currently recognized that the most effective and thorough treatment method is sludge drying and incineration, and sludge drying and incineration is closely related to the calorific value index of sludge, which is determined by the calorific value. Whether the subsequent self-sustaining combustion and auxiliary fuel consumption can have a great impact on the continuous and stable operation of the equipment and the operating economy. In fact, the ca...
