The loop inner that road 6 is constituted is filled with thermal conducting agent, and thermal conducting agent is water in the present embodiment.
As shown in Figure 1, for heat preservation, autoclave body 1, high-temperature water tank 4, up-hill line 7 and downstream pip 6 surface be provided with
Insulating layer.In order to enable the water temperature in high-temperature water tank 4 is kept constant, high-temperature water tank be internally provided with heating device of water tank 12 with
And cold water supply apparatus 13.Assisted heating device 14 is additionally provided in autoclave body 1.
As shown in Figure 1, the outside wall surface of autoclave body 1 is provided with cleaning water filling port 15, cleaning discharge outlet 16 and several vibrations
Source 17；In the present embodiment, vibration source 17 is eccentric motor, and cleaning water filling port 15 is located at the top of autoclave body 1, cleans discharge outlet 16
In the bottom of autoclave body 1.It is later on each by cleaning water filling port 15 to 1 internal water flooding of autoclave body during cleaning autoclave body 1
A vibration source 17, the inner wall of autoclave body 1 under the driving of high-frequency vibration with it inside water constantly impact so that being attached to autoclave body 1
Impurity on inner wall peels off；After the completion of vibration, cleaning discharge outlet 16 is opened, water and impurity inside autoclave body 1 is discharged.Pass through vibration
Dynamic source 17, can rapidly clean the impurity inside autoclave body 1, avoid the problem of narrow autoclave body is difficult to clean.
As shown in Figure 1, the polyphenylene sulfide polymerization reaction kettle using the present embodiment is reacted, specifically includes the following steps:
1) thermal conducting agent, this implementation will be full of in heat exchanger 3 in up-hill line 7, downstream pip 6, high-temperature heat-exchanging 5 and kettle
In example, thermal conducting agent is water；NMP, Na2S and a small amount of NaOH are packed into autoclave body 1 simultaneously；And nitrogen is poured into autoclave body 1, it protects
Material in autoclave body 1；
2) centrifugal pump 8 for opening downstream pip 6, opens throttle valve 9, and close exhaust valve 10；At this point, heat exchanger 3 in kettle,
High-temperature heat-exchanging 5, up-hill line 7 and downstream pip 6 constitute conventional heat-exchanging loop, thermal conducting agent in high-temperature heat-exchanging 5 and
It is recycled between heat exchanger 3 in kettle, and the material in autoclave body 1 is tentatively heated；When material heated up it is slow when, autoclave body can be passed through
Interior assisted heating device 14 carries out auxiliary heating to material；Material is heated to after 200 DEG C or so, closes centrifugal pump 8, is stopped
Material in autoclave body 1 is heated；
2) paracide and nmp solvent are added into autoclave body 1, in the process, blender 2 is persistently to the intracorporal material of kettle
It is stirred, is allowed to that bunching reaction occurs.Before bunching reaction occurs, it is necessary first to the exhaust valve 10 of up-hill line 7 is opened,
And exhaust valve 10 is closed when the reading of barometer 11 drops to predetermined value, so that (water steams the gaseous thermal conducting agent of discharge part
Gas) so that heat exchanger 3, high-temperature heat-exchanging 5, up-hill line 7 and downstream pip 6 are become point from conventional heat-exchanging loop in kettle
From formula heat pipe structure；
In bunching reaction process, the material in autoclave body 1 continues heat release, and the thermal conducting agent in kettle in heat exchanger 3 absorbs a large amount of
Heat, and be converted to steam；Subsequent steam is along the high-temperature heat-exchanging 5 that up-hill line 7 rises to high-temperature water tank, and steam is in high temperature
It is condensed in heat exchanger 5, condensed water is understood in kettle inside heat exchanger along downstream pip stream.Since thermal conducting agent is deposited in above-mentioned cyclic process
In phase transformation, allows thermal conducting agent more efficiently to transmit the heat of the generation of autoclave body 1, efficiently reduce exothermic heat of reaction to autoclave body
It is influenced caused by temperature in 1, the high temperature avoided in autoclave body 1 rises, the temperature range beyond the reaction of normal bunching.
When in separate heat pipe structure, high-temperature heat-exchanging 5 is cold end, and heat exchanger 3 is hot end in kettle；The isothermal of heat pipe
Matter determines that the temperature of heat exchanger 3 in kettle is not less than the temperature of high-temperature heat-exchanging 5；It may insure the object inside autoclave body 1 in this way
Material temperature degree is not less than the hot water temperature inside high-temperature water tank 4；Caused by avoiding the too low reaction to bunching of 1 internal temperature of autoclave body
Adverse effect.
Due to volume difference huge between autoclave body 1 and high-temperature water tank 4, so that the heat release in autoclave body 1 is in high-temperature water tank 4
Water Temperature it is smaller.When autoclave body 1 be in 3 to 6 it is small when bunching reaction process in, autoclave body 1 generate energy can directly lead to
It crosses up-hill line 7 and is transmitted to high-temperature heat-exchanging 5, this avoid the temperature generations in autoclave body 1 to be ramping up.And high-temperature water tank 4
Interior water temperature can be adjusted using various ways, such as be added into high-temperature water tank 4 in right amount by cold water supply apparatus 13
Cold water, or open heating device of water tank 12 and directly the water in high-temperature water tank 4 is heated, by the above means, can incite somebody to action
Water temperature in high-temperature water tank 4 maintains within the temperature range of suitable bunching reaction.
High-temperature water tank 4 absorbs amount of heat in the reaction of this bunching and its water temperature inside is made to generate a degree of liter
It is high；These heats that high-temperature water tank 4 absorbs tentatively heat the material in autoclave body 1 before can be used for next bunching reaction.
3) after reaction, the product in autoclave body 1 be cooled and separated, wash, dry can be prepared by polyphenylene sulfide original
Powder.
Combine figure embodiment that the utility model is described in detail above, those skilled in the art can root
Many variations example is made to the utility model according to above description.Thus, certain details in embodiment should not constitute practical to this
Novel restriction, the utility model will be using the ranges that the appended claims define as protection scope.
