Abstract
The utility model provides a methyl chloride reaction vessel comprising a vessel body, a skirt, a vessel cover arranged on the upper part of the vessel body, a gas distributor and a thermowell which are arranged inside the vessel body, a heat change device arranged outside the vessel body, and a gas inlet, a synthesis gas outlet, a catalyst inlet, a refluence port, a liquid discharge port, a temperature measuring port, an observing port and an emptying port which are all arranged on the vessel body and the vessel cover. The novel methyl chloride reaction vessel is of evenly distributed stuff and gas, full contact with the catalyst, high efficiency of heat transport, convenient installation and repair, and is special for the synthesis of methyl chloride gas.
Description
Technical field
The utility model relates to a kind of chemical reactor, particularly relates to a kind of tank reactor.
Background technology
At present, be used for the reactor of synthetic methyl chloride because its gas distributor structure and decoration form undesirable, can not fully and equably contact with catalyst after causing unstripped gas to enter kettle inside, cause reaction not exclusively, resultant of reaction---content of methyl chloride is on the low side; Secondly, in the selection of gas distribution tube, most reactor adopts common polyfluortetraethylene pipe to make, and this material (about 150 ℃) under temperature of reaction can produce bigger distortion, cause the variation of distribution pipe position in still, bring the factors of instability to reaction; In addition, because reaction is accompanied by the process of thermal exchange, before the reaction beginning, the material of participating in reaction need be heated to certain temperature, and in the middle of reaction is carried out, needing that again reaction is generated heat in time shifts out, in the whole process that reaction is carried out, just can keep a comparatively stable temperature range like this, for this reason, reactor must be provided with a heat-exchanger rig, and some reactor still adopts the heat exchange structure of jacketed type at present, this structure not only heat exchange efficiency is low, and because heat-conducting medium to the frequent thermal shock of still wall, causes reactor burst porcelain tendency to increase greatly, thereby influence the work-ing life of reactor.
The utility model content
The purpose of this utility model is to provide a kind of unstripped gas to mix, sufficient reacting, resultant content height, the methyl chloride reactor that heat transfer efficiency is high.
The utility model methyl chloride reactor is the liner glass-lined kettle, its structure is shown in (figure one), comprise: cylindrical shell 7, skirt 1, last lower cover 3,8, be arranged on the kettle cover 10 in upper cover centre, be arranged on the leakage fluid dram 2 on the lower cover, be arranged on the syngas outlet 12 on the kettle cover, be arranged on the inlet mouth 5 of cylindrical shell bottom, be arranged on the catalyst import 14 on cylindrical shell top, be arranged on kettle gas inside sparger 6 and thermowell 4, be arranged on phegma import 13, temperature-measuring port, drain and porthole 9 on the upper cover, be arranged on the heat-exchanger rig of kettle outside.Wherein, distribution pipe, joint flange and distribution pipe stationary installation that gas distributor is arranged by horizontal symmetrical are formed, and introduce kettle inside through the inlet mouth of cylindrical shell bottom, distribution pipe is 2～8 straight tubes that are full of aperture, and the arrangement mode in the aperture in distribution hole, quantity and hole makes it reach best effect through calculating on the distribution pipe; Distribution pipe adopts through materials such as the fluorine plastic tube of modification or carbon tubes and makes, and it is very little that these materials be out of shapes under temperature of reaction, can not cause distribution pipe position mobile in still, thereby make reaction can remain metastable state; The material that heat-exchanger rig is used for and reactor is interior that is arranged on the kettle outside carries out heat exchange, and the process of its heat exchange is to realize by the circulation of liquid catalyst between reactor and heat-exchanger rig.
The working process of the utility model methyl chloride reactor is: the unstripped gas that is preheated to certain temperature enters in the gas distributor by inlet mouth, and then be distributed to equably in the liquid catalyst by the distribution hole on the sparger, with carry out thermopositive reaction after catalyst fully contacts, reacting the methyl chloride gas that generates derives by the syngas outlet on the kettle cover, and the liquid catalyst that participates in reaction is by ceaselessly circulating the heat exchanging process of realization response between reactor and heat-exchanger rig thereof; The temperature of reaction detects and controls by temperature-measuring port.
The advantage of the utility model methyl chloride reactor is: adopted the gas distributor of being made up of the gas distribution tube of even number root horizontal symmetrical layout 1., realized unstripped gas uniform mixing and with fully the contacting of catalyst, effectively promoted reaction to carry out towards the direction of making to help resultant.2. adopted the heat exchange structure that is arranged on the kettle outside, not only simplified the structure of reactor, prolonged the work-ing life of reactor, and the heat transfer efficiency of the reactor that improves greatly.
