Multi-parameter mine spraying heat exchange efficiency calculation method-based spraying system

Abstract

The invention relates to the field of mine spraying heat exchange and specifically relates to a multi-parameter mine spraying heat exchange efficiency calculation method-based spraying system. Four different artificial intelligence calculation models are selected; multiple groups of parameters of flue gas quantities, circulating pump flow quantities, concentration, liquid-gas ratios, inlet flue gas temperature, spray slurry density, post-spray temperature and the like collected in spraying heat exchange system operation processes are used as input variables of the four models. Each model is subjected to training operation, and four nonlinear function relations between spraying parameters and heat exchange efficiency are established. Parameters that are monitored in real time are respectively transmitted to the trained artificial intelligence models, and predictions on spraying efficiency are made. The average value of two predicted values positioned at the middle of results is used as a final prediction value, the number of spray headers to be opened and a spray flow quantity are determined according to implementation data calculated via a control device, and the heat exchange efficiency can be well monitored via use of the method; compared with single model prediction, the method is characterized by high stability, strong monitoring capability and the like.

Description

technical field [0001] The invention relates to the field of mine spray heat exchange, in particular to a spray system based on a multi-parameter calculation method for mine spray heat exchange efficiency. Background technique [0002] Mine waste heat recovery and utilization has always been a big branch of energy utilization. The current mine waste heat recovery and utilization always adopts the method of spraying with simple nozzles. This method can achieve the effect of waste heat recovery to a certain extent. However, because the temperature will change and be affected by the conditions of different mines, the single spraying will cause the number of nozzles to be constant due to the unfamiliar conditions and the influence of temperature, which will cause a waste of resources to a certain extent. Contents of the invention [0003] The purpose of the present invention is to make up for the above-mentioned problems and technical gaps in the prior art, and to propose a hi...

[0002] The recovery and utilization of mine waste heat has always been a big branch of energy utilization. The current mine waste heat recovery and utilization always adopts the method of spraying with simple nozzles. This method can achieve the effect of waste heat recovery to a certain extent. However, because the temperature will change and be affected by the conditions of different mines, the single spraying will cause the number of nozzles to be fixed due to the unfamiliar conditions and the influence of temperature, which will cause a waste of resources to a certain extent.
