Abstract

The utility model relates to a vertical type cooling reaction kettle which comprises a reaction kettle. The vertical type cooling reaction kettle is characterized in that vertical condensers are arranged inside the reaction kettle. According to the vertical type cooling reaction kettle, by increase of the vertical condensers, multiple media can be uniformly distributed in the reaction kettle under a mixing function when entering the reaction kettle, and the temperature in the reaction kettle is equal. Public work conditions are easy to master, and the temperature in the reaction kettle maintains constant; and the problem that materials on the outer side of an original coiled tube can not entirely react is resolved, the chemical synthesis yield is improved, energy conservation and emission reduction are achieved, and production cost is reduced.

Description

Vertical cooling reactor

Technical field

The utility model relates to a kind of vertical cooling reactor.

Background technology

Exothermic reaction in synthetic for chemical industry, the general mode that adds coiled pipe cooler in the still that adopts solves, react for multiphase medium, because the stirring problem causes dielectric distribution inhomogeneous, exothermic reaction is too fast, cause local temperature too high, public work (referring to cooling) is caused operating influence, increase power consumption; The inside reactor subregion causes the temperature part too high because mixing effect is poor, side reaction is increased, and yield reduces.To exothermic reaction, too high because of local temperature, easily cause bumping and explosion accident.Adopt the round coil condenser, cause to form guide shell when stirring, the material reaction that stirs the outside is insufficient, and product yield is lower.

The utility model content

According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can overcome defects, can improve the vertical cooling reactor of cooling effect.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of vertical cooling reactor, comprise reactor, and it is characterized in that, be provided with vertical (type) condenser in the reactor.

Described vertical (type) condenser is two, and the paddle both sides that are symmetricly set on reactor are fixedly connected with the reactor inwall.

The beneficial effect that the utility model has is: by increasing vertical (type) condenser, make multinomial medium be uniformly distributed in reactor under the effect of stirring when entering reactor, reactor temperature is average.Grasp easily the public work condition, make reactor temperature keep stable; Solve the problem that former coil pipe outside material can not react comprehensively, improve the chemical industry synthesis yield, energy-saving and emission-reduction reduce production costs.

Description of drawings

Fig. 1 is the utility model structural representation;

Among the figure: 1, reactor; 2, vertical (type) condenser.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

Vertical cooling reactor as shown in Figure 1 comprises reactor 1, is provided with vertical (type) condenser 2 in the reactor 1.Vertical (type) condenser 2 is two, and the paddle both sides that are symmetricly set on reactor 1 are fixedly connected with reactor 1 inwall.

Take synthetic trimethyl orthoacetate technique as example, whole building-up process is carried out in the reactor of chilled brine and stirring, course of reaction is to add a certain amount of methyl alcohol and acetonitrile in reactor, under-20 ℃ of temperature environment conditions, open and stir, then pass into dry HCl gas, a large amount of heat is emitted in reaction, because former design reactor inner condenser is round coiled, when stirring, formed the water conservancy diversion whirlpool, the heterogeneous reaction medium can not fully disperse, cause the coil condenser outside material can not complete reaction, easily form peritectoid phenomenon and hot-spot and generate other accessory substances, synthesis yield be about 70%.Pass through vertical (type) condenser in the utility model, cooperate vane type to stir, condenser outside material is fully stirred, and the difficult material localized heat release phenomenon that forms the peritectoid phenomenon and cause because mixing effect is bad is well solved, and existing product reaction yield reaches about 80%.The peritectoid phenomenon is eliminated and is difficult for causing reaction heat to concentrate affects the product synthesis yield, alleviates simultaneously course of reaction making excessive demands freezing index.Synthesis yield improves 6%～10%, and unit product lowers consumption about 1000～1500 yuan/tons.

Claims

1. a vertical cooling reactor comprises reactor, it is characterized in that, is provided with vertical (type) condenser in the reactor.

2. vertical cooling reactor according to claim 1 is characterized in that described vertical (type) condenser is two, and the paddle both sides that are symmetricly set on reactor are fixedly connected with the reactor inwall.
