Description
Technical Field
The invention belongs to the technical field of factory environment light, and particularly relates to a factory intelligent exhaust system and a control method.
Background
Nowadays, when most factories or workshops produce products, toxic gas or toxic gas generated by chemical reaction circulates in the workshops, so that the bodies of workshop workers and people are influenced and damaged, however, if every workshop uses an exhaust fan every day and uses the same large exhaust speed, a lot of unnecessary electric energy is wasted.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides an intelligent exhaust system of a factory and a control method, wherein the intelligent exhaust system of the factory is simple in structure, safe, energy-saving and good in applicability.
In order to achieve the purpose, the invention adopts the technical scheme that: this kind of mill's intelligence exhaust system that provides, its characterized in that: be equipped with a plurality of exhaust fans of interval arrangement on factory outer wall of mill, every the exhaust fan all is equipped with the servo motor of its speed of control, and the controller passes through servo motor control exhaust fan speed.
In order to make the technical scheme more detailed and concrete, the invention also provides the following further preferable technical scheme to obtain satisfactory practical effect:
the plant area is internally provided with a plurality of gas concentration sensors, and the gas concentration sensors transmit detection signals to the controller.
The exhaust fan is connected to the waste gas treatment equipment through an exhaust pipeline.
The intelligent exhaust system control method of the factory, the area of the factory of reasonable division according to the detection range of the gas concentration sensor, arrange the corresponding number of exhaust fans; the gas concentration sensor detects the gas concentration of each factory area, compares with the set safety value, and when the detected harmful gas value in a certain area exceeds the safety value range, the exhaust fan corresponding to the area and the adjacent exhaust fans are controlled and started by the controller.
The excessive harmful gas is divided into three grades, and the exhaust fan is correspondingly divided into three grades according to the rotating speed.
Compared with the prior art, the invention has the following advantages: the intelligent exhaust system and the control method for the factory are simple in structure, safe, energy-saving, good in applicability, strong in practicability and good in application prospect.
Drawings
The contents of the drawings and the reference numerals in the drawings of the present specification will be briefly described as follows:
FIG. 1 is a schematic structural diagram of an intelligent exhaust system of a factory according to the present invention;
labeled as: 1. exhaust fan, 2, gas concentration sensor, 3, servo motor, 4, controller, 5, exhaust-gas treatment equipment.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
As shown in figure 1, the factory intelligent exhaust system is characterized in that a plurality of exhaust fans 1 are arranged on the outer wall of a factory area of a factory at intervals, each exhaust fan 1 is provided with a servo motor 3 for controlling the speed of the exhaust fan, and a controller 4 controls the speed of the exhaust fan 1 through the servo motor 3.
In the invention, a plurality of gas concentration sensors 2 are arranged in the plant area, and the gas concentration sensors 2 transmit detection signals to the controller 4. Controller 4 received signal controls the exhaust fan on the relevant position and starts, controls exhaust fan pivoted speed through servo motor 4 to reasonable effectual use exhaust fan 1, exhaust fan 1 is connected to exhaust-gas treatment equipment 5 through the exhaust pipe, carries out exhaust-gas treatment and discharges. If the gas concentration in the producing area is in the safe range, the exhaust fans can be stopped, or the start of each exhaust fan can be manually controlled according to the requirement.
In the invention, a control method of a factory intelligent exhaust system reasonably divides a factory area according to the detection range of a gas concentration sensor 2, and arranges a corresponding number of exhaust fans 1; the gas concentration sensor 2 detects the gas concentration of each factory area, compares the gas concentration with a set safety value, and when the detected harmful gas value in a certain area exceeds the safety value range, the controller controls and starts the corresponding exhaust fan 1 in the area and the exhaust fan 1 on the adjacent position of the corresponding exhaust fan 1 so as to ensure the safety of personnel in the factory area.
According to the invention, the concentration value of the over-standard harmful gas can be divided into three levels (different gases have different standards), the exhaust fan is correspondingly divided into three levels according to the rotating speed, and the rotating speed gear of the exhaust fan is controlled according to the detected gas concentration condition.
The exhaust fan system ventilates for the workshop, the gas concentration that gas concentration detected can be through in every how much area (set for according to workshop actual conditions) the speed of exhaust fan is controlled to the gas concentration, of course, the local gas concentration of difference is also different in the workshop, detect through different gas concentration sensor 2, if concentration in certain region is too high, exceed the safe value (according to mill's actual settlement), start suitable gear through controller 4 control corresponding position area's exhaust fan 1 promptly, realize that gas concentration detecting system controls the speed of exhaust fan through the size that detects gas concentration, when gas concentration tends to normal or safety range, can slow down exhaust fan or selective interval and open a small number of exhaust fans or stop the exhaust fan, realize energy saving and emission reduction.
The intelligent exhaust system and the control method for the factory are simple in structure, safe, energy-saving, good in applicability, strong in practicability and good in application prospect.
The invention has been described above with reference to the accompanying drawings, but the invention is not limited to the above-described embodiments, and it is within the scope of the invention to use various insubstantial modifications of the inventive concept and solutions or to apply them directly to other applications.
