The temperature collecting unit is used for collecting the temperature of the kiln combustible waste gas in the kiln combustible waste gas pipeline, the input end of the PLC control module is connected with the temperature collecting unit, and the PLC control module is suitable for controlling the work of the kiln ignition device according to the data of a pressure collecting unit and the temperature collecting unit. The device solves the solves the problem of by-product kiln combustible waste gas generated by the chemical industry production process, and reduces pollution to the atmospheric environment.
Description
Technical field
The present invention relates to industrial control field, relate to a kind of kiln combustible waste gas discharging control device.
Background technology
At present, China's boiler and kiln product are widely used in all trades and professions, but the structure of traditional burner and combustion method are unreasonable, burn and insufficiently cause energy waste large, kiln combustible exhaust gas is the byproduct producing in chemical process, wherein directly be discharged to the external world greatly, be directly discharged into air and can cause larger pollution to atmospheric environment.
Because kiln combustible exhaust gas ignition point is lower; there is not the obstacle that catches fire; to its processing of fully burning, the mist that makes waste gas become carbon dioxide and nitrogen is drained in atmosphere again, thereby reduces to greatest extent kiln combustible exhaust gas the pollution of atmosphere is reached the object of protection of the environment.
Summary of the invention
In order to overcome above the deficiencies in the prior art, the invention provides a kind of kiln combustible waste gas discharging control device and method, can effectively, environmental protection control processing kiln combustible exhaust gas.
Technical scheme of the present invention is: a kind of kiln combustible waste gas discharging control device, this device comprises collecting unit, kiln igniter and control module, the signal that collecting unit gathers the kiln combustible exhaust gas in kiln combustible exhaust gas pipeline is input to control module, and control module is sent control command control kiln igniter.Described collecting unit is pressure acquisition unit.Described collection is pressure acquisition unit and for gathering the temperature collecting cell of combustible exhaust gas temperature in kiln combustible exhaust gas pipeline.Described kiln igniter is more than 2 covers, respectively corresponding being arranged on the cellar for storing things stove of equal number.This device also comprises the host computer of real time monitoring apparatus working, and host computer and control module couple.
The present invention has following good effect: 1, host computer is monitored in real time to work, the running status of kiln combustible exhaust gas burning control apparatus for demonstrating; 2, three combustion furnaces of controller control, according to the size of manifold pressure, the number of suitable selective combustion stove.
Accompanying drawing explanation
Fig. 1 is the system construction drawing of device.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is as the effect of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present invention, technical scheme.
This device comprises pressure acquisition unit, for gathering the pressure of the kiln combustible exhaust gas in kiln combustible exhaust gas pipeline; Kiln igniter; PLC(Programmable Logic Controller, programmable logic controller (PLC)) control module, its input Bonding pressure collecting unit, output connects kiln igniter, is suitable for according to the work of the Data Control kiln igniter of pressure acquisition unit.
This device also comprises temperature collecting cell, for gathering the temperature of the kiln combustible exhaust gas in kiln combustible exhaust gas pipeline; The input of PLC control module is connected with temperature collecting cell, is suitable for according to the work of the Data Control kiln igniter of pressure acquisition unit and temperature collecting cell.
This device also comprises host computer, PLC control module adopts Ethernet to be connected with host computer, PLC analog input module gathers the current signal that kiln gas meter conducts, by output module control igniter, the work, the running status that are suitable for kiln combustible exhaust gas combustion control device are monitored in real time.Wherein host computer adopts PC.
Kiln igniter is many covers; Described PLC control module determines the duration of ignition of each kiln igniter according to the data of collecting unit collection.In this specific embodiment, kiln igniter is that 3 covers are installed on respectively 3 kilns;
PLC control module control kiln igniter (kiln combustible exhaust gas burning point firearm), this kiln igniter can adopt two kinds of control modes of automatic/hand.Automatic control mode is according to the size of kiln combustible exhaust gas pressure, automatically control 1～3 cover kiln combustible exhaust gas burning point firearm work, pressure acquisition unit 4(pressure sensor) the interior gas flow of detection pipeline, the gas flow detecting starts to light first kiln combustible exhaust gas burning point firearm reach 10mA after A/D conversion time, in the time that reaching 15mA after A/D conversion, gas flow continuation increase opens second kiln combustible exhaust gas burning point firearm, in the time that reaching 20mA after A/D conversion, gas flow continuation increase opens the 3rd kiln combustible exhaust gas burning point firearm.In the time that automatic control is malfunctioning, the fault message of the PLC output fault-signal of naming a person for a particular job, the audible-visual annunciator in control room will be reported to the police, and staff can beat as manual mode by change-over switch on console, with manual control mode control 1～3 cover kiln combustible exhaust gas burning point firearm work.
Embodiment mono-:
Pressure acquisition unit detects gas flow in pipeline, when the gas flow detecting reaches 10mA after A/D conversion, PLC control module is opened first kiln igniter, in the time that gas flow continuation increase reaches 15mA after A/D conversion, PLC control module is opened second kiln igniter, and in the time that gas flow continuation increase reaches 20mA after A/D changes, PLC control module is opened the 3rd kiln igniter.
Embodiment bis-:
According to actual needs, can serviceability temperature collecting unit (temperature sensor) and pressure sensor gas in pipelines temperature and pressure signal is gathered.The temperature and pressure signal of temperature sensor and pressure sensor collection is converted into the current signal of 4～20mA, selects 4 passages of analog input module S7-300AI module to receive simultaneously and process the current signal of 4～20mA.
The current signal that PLC control module while detected temperatures and pressure are passed back; Temperature signal priority is higher than pressure signal, and when temperature feedback in pipeline is during lower than 8mA, no matter pressure feedback is how many, all opens 3 igniters; When temperature feedback is during in 8～16mA, igniter of every grade of increase on example one basis; When temperature feedback is during higher than 16mA, adopt example one mode to light a fire.This mode can the current waste gas burning situation of more effective detection, more thoroughly purifies kiln waste gas.
The input and output point distribution condition of PLC control module (PLC controller), wherein, distributes the input/output module of Siemens S7-300, as shown in table 1, table 2.
