Description
Technical field
The utility model relates to control system technical field, is specially a kind of reactor heating closed-loop control system.
Background technology
According to the current production scene of reactor situation, the feeding of reactor is Artificial Control completely, deliver to reactor by magnetic drive pump from head tank, due to the difference of product, the viscosity of mixed material and more not identical than weight average, therefore, in unit interval, the raw material weight of magnetic drive pump conveying is different variation, the chemical reaction velocity of reactor, depends on raw material to a great extent, and Oxidizing and Reducing Agents add speed. Now can only be by the artificial temperature according to reactor and outlet temperature, judge roughly the chemical reaction situation in reactor, by-pass valve control aperture, so is just difficult to really control well chemical reaction velocity, makes the stability of product quality and the further production capacity that improves reactor all be subject to restriction.
Utility model content
The purpose of this utility model is to provide a kind of reactor heating closed-loop control system, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of reactor heating closed-loop control system, comprise industrial computer, the output of described industrial computer is electrically connected with the input of Programmable Logic Controller, the output of described Programmable Logic Controller respectively with head tank electric-control stop valve, oxidant tank electric-control stop valve, reducing agent tank electric-control stop valve, cooling water backwater control valve, instantaneous delivery calculates device, the input of average discharge calculation element and outlet temperature checkout gear is electrically connected, the input of the output of described head tank electric-control stop valve and raw materials electric control valve is electrically connected, the input of the reinforced electric control valve of the output of described oxidant tank electric-control stop valve and oxidant is electrically connected, the input of the reinforced electric control valve of the output of described reducing agent tank electric-control stop valve and reducing agent is electrically connected, described Programmable Logic Controller is the two-way single-chip microcomputer that is electrically connected with also, described single-chip microcomputer is the two-way temperature controller that is electrically connected with also, the output of described temperature controller is also electrically connected with the input of power regulating eqiupment and thermocouple respectively.
Preferably, the output of described Programmable Logic Controller is also electrically connected with the input of alarm and status indicator lamp respectively.
Compared with prior art, the beneficial effects of the utility model are: this reactor heating closed-loop control system principle is simple, can understand in time injection instantaneous velocity and the average speed of raw material, Oxidizing and Reducing Agents according to the weighing-up wave of electronic scale, at a set of electric control valve of Increasing exports of head tank magnetic drive pump, and on the pneumatic conveying pump line road of oxidant, reducing agent, then distinguish each installation electric control valve.
