Description
[technical field]
The utility model relates to a kind of chemical industry equipment, particularly a kind of temperature of reaction kettle double-control apparatus that is used for polyester polyol production.
[background technology]
During polyester polyol is produced in the process, generally be to adopt thermal oil to reach the required temperature of reaction by interlayer circulation heating, the thermal oil temperature is 270-280 ℃, heating-up time is 12-14 hour, and the qualified back of product temperature fall time, also be to circulate by interlayer cold oil to cool off, generally need 3-4 hour, but because the product temperature fall time is longer, less stable, therefore how to solve in the polyester polyol production intensification in the process and cross slow and the slow problem of lower the temperature, become the problem that needs research and solve as early as possible and inscribed.
[utility model content]
The purpose of this utility model is to provide a kind of and can be rapidly heated in polyester polyol production reaction process, the polyester polyol temperature of reaction kettle double-control apparatus of fast cooling.
The utility model is achieved through the following technical solutions:
A kind of polyester polyol temperature of reaction kettle double-control apparatus, comprise reactor, water pump and pond, it is characterized in that: be provided with a volution circulating pipe along the winding of reactor sidewall in the described reactor, this circulating pipe one end and rising pipe are connected to the pond, the other end with also be communicated with to the pond after water pump is connected, position near reactor on the described rising pipe also is provided with steam inlet, and the position near reactor on the described water inlet pipe also is provided with a vapour outlet.
Described reactor top is provided with an opening for feed.
Described steam inlet and vapour outlet are equipped with steam valve and control its folding.
Described reactor sidewall is provided with the heat conduction oil reservoir, is respectively equipped with the outlet of heat conductive oil inlet and thermal oil on the heat conduction oil reservoir.
Be equipped with circulating-water valve on described water inlet pipe and the rising pipe in order to the control current.
The utility model adopts the volution circulating pipe steam heating system and the circulating water cooling system of twining along sidewall is set on the reactor inwall, adopt this mode, when beginning to heat up, open the steam valve of volution circulating pipe steam inlet, because the material in the reactor is direct and tube contacts, heat-up rate is accelerated, and approximately duration is just can finish intensification in 8-10 hour; And, open the circulating-water valve of water inlet pipe in when cooling, and introduce water coolant directly to contact with the quickening cooling rate with material in the reactor, generally be cooled to and can pack discharging time and be about 45 minutes to one hour.Use this device to greatly reduce the production cycle, reduce the energy and consume, product stability is better.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of the utility model polyester polyol temperature of reaction kettle double-control apparatus.
[embodiment]
Seeing also Fig. 1, is the structural representation of the utility model polyester polyol temperature of reaction kettle double-control apparatus
Figure, a kind of polyester polyol temperature of reaction kettle double-control apparatus comprises reactor 1, water pump 2 and pond 3, and the sidewall of reactor 1 is provided with heat conduction oil reservoir 11, is respectively equipped with heat conductive oil inlet 12 and thermal oil outlet 13 on the heat conduction oil reservoir 11.Be provided with a volution circulating pipe 14 along the winding of reactor 1 sidewall in the reactor 1, one end of this circulating pipe 14 is connected to pond 3 by rising pipe 4, the other end of this circulating pipe 14 is with after water inlet pipe 5 is connected, also lead to pond 3 by water pump 2 connections, rising pipe 4 and water inlet pipe 5 be provided with circulating-water valve 41 in order in order to control current, position near reactor 1 on the described rising pipe 4 also is provided with steam inlet 42,42 are provided with steam valve 43 its foldings of control on the described steam inlet, position near reactor 1 on the described water inlet pipe 5 also is provided with vapour outlet 51, also be provided with steam valve 52 control foldings on the vapour outlet 5, reactor 1 top is provided with an opening for feed 15, in order to inside input material.
In the use when needs begin to heat up, the steam valve of opening earlier on the steam inlet 42 of volution circulating pipe 14 43 heats, because the material in the reactor 1 directly contacts with the pipeline of volution circulating pipe 14, heat-up rate is accelerated, and approximately duration is just can finish intensification in 8-10 hour; And when cooling, close the steam valve 43 on the steam inlet 42 of volution circulating pipe 14, open the circulating-water valve 41 of water inlet pipe 5, opening the water coolant that water pump 2 introduces in the ponds 3 directly contacts with the quickening cooling rate with material in the reactor 1, generally be cooled to and pack discharging time and be about 45 minutes to one hour, use this device to greatly reduce the production cycle, reduce the energy and consume, and product stability is better, has very high using value.
