Embodiment Construction
[0041] According to the accompanying drawings in the following figure 1 , and the embodiment further illustrates the invention.
[0042] like figure 1 As shown, the present invention is characterized in that it is composed of the central control computer located in the central control room of the cement plant, the distributed smoke and dust control computer located in the field, and the smoke and dust collection, flue gas measurement and waste heat utilization equipment located in all the smoke and dust discharge points on the site. In the DCS distributed cement production and waste heat power generation system, the smoke and dust produced by limestone decomposition, clinker calcination and coal combustion in the clinker workshop are monitored. It has the functions of decentralized control on site and centralized management by central control computer. The following steps are implemented to monitor:

The invention discloses a method for monitoring cement production soot emission and waste heat power generation system soot emission, and belongs to the technical field of industrial soot emission monitoring. The method for monitoring the cement production soot emission and the waste heat power generation system soot emission is characterized by comprising the steps of after soot passes through a soot collector, transmitting soot quantity which is not caught to a center control computer located in a central control room through distributed control computers according to soot quantity sensors installed at measuring points of a cement production field, comparing the soot quantity which is not caught with a threshold value under cement production and waste heat power generation working conditions, judging whether the soot quantity which is not caught reaches the standard or not, and if the soot quantity which is not caught exceeds the standard, sending control commands to the distributed control computer located on the measuring point by the center control computer until the soot quantity which is not caught reaches the standard. When industrial waste is co-processed by a cement furnace, the control threshold value is improved by 10%. According to the method for monitoring the cement production soot emission and the waste heat power generation system soot emission, production greenization of a cement factory can be ensured, and harmonization of a production environment when the waste heat power generation system and the cement furnace co-process the waste can also be considered.
Description
technical field [0001] The invention belongs to the technical field of industrial smoke and dust discharge monitoring, and in particular relates to a monitoring method for smoke and dust discharge of cement production and waste heat power generation systems. Background technique [0002] The invention discloses a monitoring method for smoke and dust discharge of cement production and waste heat power generation systems, and belongs to the technical field of industrial smoke and dust discharge monitoring. [0003] The dust in the cement plant refers to the solid particles or aerosols produced by the high-temperature combustion of fuel coal and raw materials together in the calciner and rotary kiln. In the traditional cement production process, the emission sources of smoke and dust are mainly the kiln head and the tail of the kiln. Generally, dust collectors are installed at these two places to reduce the emission of smoke and dust, in order to meet the national standard for ...
