Embodiment 1

[0018] exist figure 1 In the three-dimensional schematic diagram of a temperature control device for controlling the heating or cooling of the reactor shown in the figure, it consists of the electric control cabinet 1 system, the heating system 2, the cooling system 3, the reactor 4 system, the oil storage tank 5 system and the oil delivery system constitute.

[0019] The signal transmission line 6 of the electric control cabinet 1 system is connected with the temperature sensor 7 on the reactor 4 body, connected with the switch cabinet and the three-way valve of the heating 2 system, and connected with the oil pump 10 on the oil supply pipe 8 and the oil return pipe 9 ; The electric control cabinet 1 is connected to the power supply.

[0020] The oil supply pipe 8 output by the heating 2 system is connected with the oil outlet pipe 14 of the cooler 3 through a three-way valve, and the outlet of the three-way confluence valve is connected with the oil inlet pipe of the reacto...

Embodiment 2

[0026] Adopt the working principle of embodiment one, heating source adopts steam, electricity, gas; Cooling source adopts factory cooling water or chilled water, or refrigeration equipment; Adopt the working principle of embodiment one, control the temperature of multiple reactors 4 simultaneously. This new complete set of equipment integrates the traditional characteristics of the system. The parts selection design matches the system and can be adjusted within a certain range. It works according to the process setting curve and can control one reactor 4 or multiple reactors 4 at the same time. temperature.

Abstract

The invention relates to a temperature device for controlling the heating or the cooling of a reaction kettle, which is characterized in that a signal conducting wire of an electrical control cabinet is connected with a temperature sensor of a reaction kettle body, a switch cabinet and a three-way valve of a heating system and oil pumps of an oil delivery pipe and an oil return pipe; the electrical control cabinet is connected with a power supply; the oil delivery pipe output by the heating system is connected with an oil pipe output by a cooler through the three-way valve; an outlet of the three-way converging valve is connected with an oil inlet pipe of the reaction kettle through a pipeline; a circulating oil pump is arranged on the oil return pipe; and a slippage pump of the circulating oil pump is arranged on an oil supplementing pipeline positioned between an oil storage tank and an expanding oil tank. When materials inside the reaction kettle are heated to certain temperature by oil which flows to a clamping sleeve of the reaction kettle, the temperature sensor which is embedded into the reaction kettle body sends signals back to the electrical control cabinet, and the electrical control cabinet sends a command to the heating system to adjust heating power or stop heating or partly start a cooling loop of the three-way valve so as to enable the reaction kettle to internally keep preset temperature. The whole temperature device is controlled by procedures, thereby meeting a requirement for automated management of factories.

Description

technical field [0001] The invention relates to the field of reactor temperature control, in particular to a temperature control device for controlling the heating or cooling of the reactor Background technique [0002] Reactor is a chemical reaction vessel, where various substances react chemically according to the design process. The heat transfer oil temperature control device of the reaction kettle uses the heat transfer oil as the medium to indirectly heat or cool the materials in the kettle to meet the process needs. The traditional reactor control can only control the oil temperature, and a series of manual operations can meet the requirements of the kettle temperature. The control accuracy is low, and it depends heavily on skilled workers. Production accidents may also occur due to manual operation errors. Contents of the invention [0003] The object of the present invention is to provide a temperature control device for controlling the heating or cooling of the ...
