Abstract
The utility model relates to a chlorination reaction automatic control system. The chlorination reaction automatic control system comprises a reactor and a hydrogen chloride inlet pipe communicated with the reactor, and is characterized in that a temperature sensor is mounted at the top of the reactor, a pneumatic control valve is mounted on the hydrogen chloride inlet pipe, and the pneumatic control valve and the temperature sensor are connected into a DCS (distributed control system). The DCS controls the pneumatic control valve to introduce hydrogen chloride gas according to an output signal of the temperature sensor, when the temperature is too low, the intake quantity is increased, and when the temperature exceeds a set value, the intake quantity is reduced, and the chlorination reaction automatic control system can further ensure reaction efficiency and simultaneously prevent the temperature in the reactor from being too high. The chlorination reaction automatic control system can further prevent the operation staff from causing safety accidents due to negligence; and in addition, the operation staff does not need to perform operation on the spot, and even an abnormal situation occurs in the reactor, the personal injuries of the staff can be avoided and the safety can be greatly improved.
Description
Technical field
The utility model relates to a kind of automatic control system, particularly a kind of chlorination reaction automatic control system.
Background technology
Chemical enterprise need be installed manual modulation valve on the air inlet pipe that traditional method adopts with reactor is communicated with to feeding hydrogen chloride gas in the reactor as reaction raw materials when carrying out chlorination reaction.During concrete air feed, because air demand is chain with reactor temperature, so operating personnel operate manual modulation valve according to the thermometer that is provided with on the reactor and change flow, the control of realization various inlet amount.The shortcoming of this kind structure is: if operating personnel cause carelessness, forget the adjusting manual modulation valve, then possibly reduce reaction efficiency, or cause reactor temperature too high, cause security incident.
Summary of the invention
The technical problem that the utility model will solve provides the high chlorination reaction automatic control system of a kind of security performance.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of chlorination reaction automatic control system; Comprise reactor, and the hydrogen chloride air inlet pipe that is communicated with reactor, it is characterized in that: said reactor head is equipped with temperature sensor; On the said hydrogen chloride air inlet pipe pneumatic control valve is installed, said pneumatic control valve and temperature sensor all insert DCS control system.
The advantage of the utility model is: DCS control system controls pneumatic control valve according to the output signal of temperature sensor and feeds hydrogen chloride gas; Temperature is crossed when hanging down; Strengthen air inflow; And temperature then reduces air inflow when surpassing setting value, can not cause reactor temperature too high when guaranteeing reaction efficiency.Change uncontrollable manual operation into controlled operation, avoid operating personnel to neglect and cause security incident, in addition; Operating personnel need not to operate at the scene; In time unusual condition appears in reactor, also can not cause the life injury to personnel, has improved security greatly.
Description of drawings
Fig. 1 is the utility model chlorination reaction automatic control system structural representation.
The specific embodiment
As shown in Figure 1; Comprise reactor 1, and the hydrogen chloride air inlet pipe 2 that is communicated with reactor 1, at reactor 1 top temperature sensor 3 is installed; Pneumatic control valve 4 is installed on the hydrogen chloride air inlet pipe 2, and pneumatic control valve 4 all inserts DCS control system 5 with temperature sensor 3.During use; DCS control system 5 controls pneumatic control valve 4 according to the output signal of temperature sensor 3 and feeds hydrogen chloride gas; The temperature that temperature sensor 3 detects is crossed when low, and then 5 controls of DCS control system start control valves 4 and strengthen open degree and strengthen air inflow, and temperature is when surpassing setting value; Then reduce air inflow, can not cause reactor temperature too high when guaranteeing reaction efficiency.
