The intelligent control mechanism further comprises a drive system which is connected with the PLC controller and a steam soot-blowing pipe, wherein a temperature sensing device is fixed at the front end of the steam soot-blowing pipe, and the temperature sensing device is connected with the DCS control system through a data line. The intelligent control mechanism prolongs the service lifetime of a steam soot-blowing pipe and saves energy.
Description
Technical field
The utility model relates to industrial heating furnace and boiler energy-saving technical field, particularly a kind of Based Intelligent Control mechanism of steam soot-blower.
Background technology
Steam soot-blower is one of auxiliary setting of coal-burning boiler indispensability, is used for removing the boiler heating surface dust stratification, to improve boiler thermal output, reduces energy resource consumption.In boiler running process, because the temperature of burner hearth is very high, expand with heat and contract with cold or reason such as setting angle deviation often makes the distortion of soot blower gear train sink, limit position extrusion or come off before causing, cause malfunctioning switch to lose entering the feedback signal of position, thereby blowing tube is being advanced always, can not withdraw from automatically, can cause blowing tube to be exposed in the high-temperature flue gas for a long time, life-span reduces greatly, and steam blows for a long time on heating surface, can cause major injury to heating surface, booster etc. very easily occurs, have a strong impact on the operation of equipment.
The utility model content
The purpose of this utility model is the serviceable life that prolongs the steam soot blowing pipe, energy savings.For this reason, the utility model proposes a kind of Based Intelligent Control mechanism of steam soot-blower.
The technical scheme that the utility model provides is:
A kind of Based Intelligent Control mechanism of steam soot-blower comprises:
Control system, described control system comprise PLC controller and DCS control system, and described PLC controller is connected by lead with described DCS control system;
Drive system, described drive system is connected with the steam soot blowing pipe with described PLC controller;
Wherein, described steam soot blowing pipe front end fixedly has temperature sensitive device, and described temperature sensitive device is connected with the DCS control system by data line.
Preferably, in the Based Intelligent Control mechanism of described steam soot-blower, described temperature sensitive device is temp-sensitive sensor.
Preferably, in the Based Intelligent Control mechanism of described steam soot-blower, described temp-sensitive sensor is film-type thermocouple sensor or thermal resistance sensor.
Preferably, in the Based Intelligent Control mechanism of described steam soot-blower, described drive system is actuate actuators.
In the Based Intelligent Control mechanism of steam soot-blower described in the utility model, the front end of described steam soot blowing pipe fixedly has temperature sensitive device, replaced the control of preceding limit bit switch, temperature variation around the described steam soot blowing pipe in the burner hearth of perception in time, and the temperature variation signal passed to described control system, described control system is assigned to described drive system and is driven order, the described steam soot blowing pipe of described drive systems withdraws from from burner hearth, avoid excessively being heated, prolonged the serviceable life of steam soot blowing pipe, reduced and excessively blown ash, energy savings.
Description of drawings
Fig. 1 is the structural representation of the Based Intelligent Control mechanism of described steam soot-blower.
Embodiment
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do simple the introduction to needed accompanying drawing in embodiment or the description of the Prior Art below.
The utility model provides a kind of Based Intelligent Control mechanism of steam soot-blower, comprising:
Control system, described control system comprise PLC controller and DCS control system, and described PLC controller is connected by lead with described DCS control system;
Drive system, described drive system is connected with the steam soot blowing pipe with described PLC controller;
Wherein, described steam soot blowing pipe front end fixedly has temperature sensitive device, and described temperature sensitive device is connected with the DCS control system by data line.
In the Based Intelligent Control mechanism of described steam soot-blower, described temperature sensitive device is temp-sensitive sensor.
In the Based Intelligent Control mechanism of described steam soot-blower, described temp-sensitive sensor is film-type thermocouple sensor or thermal resistance sensor.
In the Based Intelligent Control mechanism of described steam soot-blower, described drive system is actuate actuators.
In the utility model, the relevant service data of the existing boiler of DCS control system is collected the PLC controller for the routine data analysis, realize data sharing, the PLC controller enters to be rotated in the boiler furnace by actuate actuators driving steam soot blowing pipe and blows ash.When perceiving temperature around the steam soot blowing pipe, the film-type thermocouple sensor that is fixed on steam soot blowing pipe front end is higher than the grey temperature of blowing of setting more than 10 ℃ the time, the film-type thermocouple sensor passes to the DCS control system with induced signal by data line, and then by actuate actuators the steam soot blowing pipe is withdrawed from burner hearth, guaranteed that steam can not blow on the heating surface of boiler for a long time, prolong the serviceable life of equipment, improved the security of operation.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in instructions and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
