The specific embodiment
System of the present utility model forms referring to Fig. 1, and it is to utilize electronic fuel (gas) jet control system and frequency conversion speed-adjusting system, and fuel and air feed are carried out real-time dynamic adjustments, thereby reaches a kind of control device of environmental protection and energy saving.It comprises: the universal industrial automaton PLC that realizes closed-loop control; Temperature sensor, pressure sensor and the gas signal that are connected with the signals collecting end of universal industrial automaton PLC as the feedback signal collection; The executing agency that comprises controlled fuel injection system, variable frequency regulating speed control air-introduced machine and variable frequency regulating speed control air blast composition that is connected with universal industrial automaton PLC control end; Control panel with simulation demonstration and soft-touch control; Described controlled fuel injection system has a common automatically controlled nozzle.
The concrete course of work of the present utility model is as follows:
Preparation work: connect power supply, push corpse, the cigarette lock is raised to a high position, starts working: control panel is seen accompanying drawing 3,4; See accompanying drawing 3 by automatic operation key; By the beginning key, enter and select the heavy and corpse temperature picture of corpse, corpse heavily is divided into gently, in, heavy, three kinds, corpse temperature branch freezing with two kinds of normal temperature, if do not select, enter next program automatically after 5 seconds, this selection is given tacit consent to according to preestablishing.Enter the phase I of cremating; based on the flue dust feedback signal, air-introduced machine is by preestablishing the revolution starting, and air blast is according to preestablishing the revolution starting; fuel sprays; the igniting baffle plate rises, and burning torch energising igniting is if light a fire successfully; furnace temperature rises; feed back to PLC, burning torch outage, baffle plate landing; the protection burning torch is avoided high-temperature baking; this moment, furnace temperature raise, and clothing on the corpse and paper coffin etc. burn, and flue dust increases; the flue dust signal feedback reduces to PLC control air blast revolution; distributive value reduces, up to the clothing all burnt, and about about 10 minutes of this process.When flue dust reduces its blow rate required and distributive value progressively increase under the control of flue dust signal.If igniting is unsuccessful, furnace temperature is constant, and PLC control point firelock is lighted a fire again, if three igniting are unsuccessful then program is out of service, reports to the police also to show the fault title.
Enter second stage, mainly based on furnace temperature and furnace pressure feedback signal, at this moment the air blast revolution reaches maximum, if it is very fast that remains fattiness temperature raises, then reduce fuel delivery, until fuel cut-off, if temperature rise slowly increase fuel delivery, this process is detected and is controlled by PLC.When furnace temperature rose to 800 degrees centigrade, remains reached the temperature of pyrolytic gasification, but fuel cut-off burns by furnace high-temperature, if cremate to freezing corpse then whole process oil-break not, the back air blast that finishes of cremating shuts down ash discharge, this end-of-job enters next circulation.
If last end-of-job is then pressed end key, then air-introduced machine cools off furnace temperature to 450 degree centigrade shutdown insulation by the low-speed running of setting.
When selecting manually operation, see accompanying drawing 4; Feedback signal is presented on the imitation screen as observation signal, the fuel supply, and air-introduced machine, air blast have only two kinds of states of break-make, by the Artificial Control combustion process.
In when, under above two kinds of mode of operations emergency taking place, can be by emergency stop push button, then whole system quits work.
Because insulation, the intensification situation of various bodies of heater are inconsistent,, need revise for the different body of heater slightly difference of the running parameter that uses of programming.
The utility model controller, is handled through PLC as the closed loop feedback signal by signals such as furnace temperature, furnace pressure and flue dust cleanliness, controls controllable fuel spraying system, frequency control induced draught system and frequency control blower system.The explanation of this electrical equipment control only illustrates the situation of a frequency conversion speed-adjusting system of PLC control, sees accompanying drawing 2; Remaining control situation roughly the same.
The starting operation of frequency converter is by the FWD of the Y1 control frequency converter of PLC, and the upper and lower limit signal of frequency detecting is respectively by the lead-out terminal function Y2 of frequency converter, X6, the X7 input that Y3 exports PLC to.Frequency converter X2 input is hand, automaticallyes switch when adjusting, and the cancellation of PID order is by the output Y6 supply signal of PLC.Total output of reporting to the police connects X5 and the COM end of PLC, and when system broke down, the output contact signal was passed to PLC, controls Y1 immediately by PLC and disconnects, and stops output.PLC input SB1 is a start button, and SB2 is for stopping knob, and SB3 is hand, automatic switchover, and SB4 is the start button of manual mode frequency converter.When controlling automatically, send the analog signal of the 4-20MA that changes the motor operating frequency by the Y0 of PLC, frequency converter changes frequency according to signal magnitude, thereby adjust the size that rotation speed of fan changes air quantity, can control the temperature and the gas component content of combustion chamber, frequency converter simulation output 0-10V feeds back to PLC and controls and monitor.
Flow process of the present utility model is referring to Fig. 5: enter control picture and selecting operational mode: divide manually operation and two kinds of operations automatically, during manual mode of operation, carry out the break-make of corresponding mechanism operates according to load button, automatically entering during operational mode selects corpse heavy, corpse temperature picture, corpse heavily divides gently, in, weigh three kinds, the corpse temperature is divided normal temperature, freezing two kinds, do not enter next program after not being chosen in 5 seconds, this selection is by preestablishing acquiescence, and next program is that air inducing frequency converter and air blast frequency converter start by setting revolution, fuel sprays, igniting, unsuccessful igniting again is if three igniting are unsuccessful, then program is out of service, reports to the police and demonstration fault title.If light a fire successfully then furnace temperature rising controller keeps running status, enter next program, flue dust cleanliness signal and furnace temperature, furnace pressure signal feedback reach optimum state to the PLC control blow rate required and fuel delivery dynamic change, make burning more abundant.
