Abstract

The invention discloses an intelligent control method of a biomass hot blast stove. The method is achieved through a PLC control system. The method includes: using a temperature collecting module to collect the output hot blast temperature of the hot blast stove, converting the collected analog value into a digital value through an analog to digital converter, inputting the digital value into a core control module, and by the core control module, controlling a fuel feeding system and an air inlet quantity control system which are connected with the core control module to change the fuel quantity of the hot blast stove or the quantity of a combustion medium so as to change hot blast temperature according to the preset temperature value and the collected value. By the intelligent control method, automatic operation of the biomass hot blast stove is achieved, precise control is achieved, and errors caused by manual operation are avoided. In addition, the whole control method is simple in process, simple in application, low in cost and suitable for being popularized and used.

Description

technical field [0001] The invention relates to the technical field of hot blast stove control, in particular to an intelligent control method for a biomass hot blast stove. Background technique [0002] Most of the existing hot blast stove automatic control systems are suitable for blast furnace hot blast stoves with very high temperature requirements. These control systems are too costly to control hot blast stoves with low temperature requirements such as drying grains and medicinal materials. At the same time, these control systems The system is very complicated and not suitable for promotion, so it is urgent to reduce the cost of the hot blast stove control system. [0003] Patent CN104482658A discloses an intelligent control system for a gas hot blast stove, which provides an intelligent control system for a gas hot blast stove with low cost and precise control. However, the corresponding intelligent control method is only applicable to gas-fired hot blast stoves, but...
