Abstract
A method for controlling the temp of reactor by use of circulated hot water features that the hot water is filled in the jacket of reactor for heating it in such manner that the flow of hot water is more than 100 ton/hr and the temp difference between water inlet and outlet is not more than 5 deg.C.
Description
Technical field
The present invention relates to the temperature-controlled process of the reactor in the industries such as being widely used in chemical industry, pharmacy.
Background technology
At present, in industries such as chemical industry, pharmacy, the mode of heating of reactor mainly contains two kinds: electrical heating and Steam Heating.Though it is these two kinds of mode of heatings can improve the temperature of reactor soon, not ideal for the temperature control of reactor.Major defect is: the fluctuation of temperature is bigger, when temperature of reaction kettle reaches setting value, can not be constant well on setting value, and this is very unfavorable to industrial production.
Summary of the invention
At the problems referred to above, the present invention will provide a kind of can make the temperature in the reactor be stabilized in the interior control method of range of set value well.
The technical solution used in the present invention is: the control method of described temperature of reaction kettle, be characterized in: reactor is heated toward the interior hot water that feeds of the chuck of reactor, and the flow of hot water is per hour more than 100 tons, and the temperature difference of chuck water inlet and delivery port is no more than 5 ℃.
The further technical scheme of the present invention is: the hot water that feeds in the chuck is circulating hot water.
The present invention further technical scheme is: with hot water line that chuck communicates on also adopted high-order water seal.
Advantage of the present invention is: the good stability of reactor temperature control helps industrial production; And temperature-rise ratio is more steady, sudden change can not occur, and the security reliability when making reactor work is higher.
Description of drawings
Fig. 1 is a preferred embodiment of temperature of reaction kettle control method of the present invention;
Fig. 2 is the design sketch that utilizes the concrete control temperature that method of the present invention obtains.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, be a preferred embodiment that realizes temperature of reaction kettle control method of the present invention; It mainly is made up of automatic control and adjustment device 1, circulating line 2, hot water circulating pump 3, Venturi tube 4, check-valves 5, stop valve 6, pneumatic stopping valve 7, pneumatic control valve 8, reacting kettle jacketing outlet temperature sensor 9, reacting kettle jacketing inlet temperature sensor 10, reactor temperature sensor 11, reacting kettle inner pressure sensor 12, high-order water seal 13, recirculated water adopter 14 etc.
Groundwork principle embodiment illustrated in fig. 1 is: reacting kettle jacketing outlet temperature sensor 9, reacting kettle jacketing inlet temperature sensor 10 and reactor temperature sensor 11 detected signals are input in the automatic control and adjustment device 1 as parameter, judge and give an order by it, control the action of steam pneumatic stopping valve 7 and cold water pneumatic control valve 8, realize the effect of A.T.C.Pressure signal P in the described reactor also is input in the automatic control and adjustment device 1 as parameter, but does not participate in temperature control, and when pressure surpassed setting value, automatic control and adjustment device 1 can send alarm signal, and this is secure to the security of producing.Described hot water circulating pump 3 is large flow pipe road pumps, and its flow is per hour more than 100 tons.Adopt Venturi tube 4 can allow heating steam fully mix, and can reduce the vibration of steam when mixed with water, make the vibration reduction of circulating line 2 with recirculated water.Adopt high-order water seal 13 can improve the temperature of recirculated water, aqueous water is the highest can only to reach 100 ℃ owing to depressing at normal atmosphere, in order to surpass 100 ℃, must improve the pressure in the circulatory system, so adopted the method for high-order water seal.Adopting check-valves 5 is for the hot water in the circulating line 2 is flowed toward a direction.Adopting pneumatic stopping valve 7 is to control for the on-off to steam.Adopting pneumatic control valve 8 is to regulate control to the size that enters the cold water water yield in the circulating line 2.The effect of stop valve 6 is to turn-off circulating line 2 in needs.The effect of recirculated water adopter 14 is the water that overflows from high-order water seal 13 can be back in the storage cistern 15, with the conserve water resource.
As shown in Figure 2, the desired temperature in the reactor is 101 ℃ in the present embodiment.When system enters the temperature rise period, when reactor temperature steadily reaches 95 ℃, automatic control and adjustment device 1 control pneumatic stopping valve 7 is closed, steam stops recirculated water being heated, the temperature in the reactor utilizes thermal inertia to continue to rise.At the same time, automatic control and adjustment device 1 can be controlled 8 moments of pneumatic control valve and open a bit, can from storage cistern 15, advance some cold water in circulating line 2 like this, allow circulating line 2 and hot water temperature in the chuck 16 rise slowly, avoid the Yin Wendu rising too fast and to break through the temperature of setting a lot.When the temperature in the reactor reaches setting value 101 ℃ the time, system enters holding stage, automatic control and adjustment device 1 continues to control the open and close of steam pneumatic stopping valve 7 and cold water pneumatic control valve 8 according to reacting kettle jacketing outlet temperature sensor 9, reacting kettle jacketing inlet temperature sensor 10 and reactor temperature sensor 11 detected signals, thereby reaches the purpose of A.T.C.By temperature control design sketch shown in Figure 2 as can be seen, the insulation curve of native system is straight line substantially, and this is very favourable to producing, and this also is the great advantage of temperature-controlled process of the present invention.
Claims (3)
1, the control method of temperature of reaction kettle is characterized in: feeding hot water in the chuck of reactor comes reactor is heated, and the flow of hot water is per hour more than 100 tons, and the temperature difference of chuck water inlet and delivery port is no more than 5 ℃.
2, control method according to claim 1 is characterized in that: toward the interior hot water that feeds of chuck is circulating hot water.
