Reactor for sec.-butyl acetate

Abstract

The invention provides a reactor for sec.-butyl acetate. The reactor comprises a reactor main body, wherein the reactor main body comprises a liquid inlet device and a temperature measuring device, the liquid inlet device comprises a liquid inlet plate, an annular plate and a flow guiding baffle, liquid inlets are formed in the liquid inlet plate and comprise upper liquid inlets and lower liquid inlets, the upper liquid inlets decrease gradually towards the two sides of the liquid inlet plate, the lower liquid inlets increase gradually towards the two sides of the liquid inlet plate, flow guiding holes are formed in the flow guiding baffle, the temperature measuring device comprises a connecting tube, a flange, a blind flange, a top cover and a temperature measuring tube, a tetrafluoro coating pad is arranged between the blind flange and a protection plate and serves as a sealing element, and the top cover and the blind flange are filled with asbestos packing. According to the reactor, the structure is simple, and the design is reasonable; by adopting disc-ring-shaped annular liquid inlet, the balance of liquid inlet flow velocity and heat exchange efficiency are guaranteed, and the energy consumption is lowered; the flow guiding baffle plays a role in guiding flow, and thus the stability of liquid inlet is guaranteed; and the temperature measuring device is excellent in sealing performance and pressure resistance and is not prone to leakage, so that the heat exchange effect and temperature measurement accuracy are improved and guaranteed.

Problems solved by technology

[0003] During the reaction process of sec-butyl acetate, it is necessary to exchange heat through the heat exchanger installed in the reactor, and in the process of heat exchange, the staff need to keep abreast of the heat exchange temperature of the heat exchanger in order to conduct Adjust and prevent overloading of the heat exchanger. Most of the temperature measuring devices currently used are affected by the installation structure, and there are many shortcomings such as poor sealing effect and low pressure resistance, which leads to leakage at the installation position, which not only affects the actual performance of the heat exchanger. The heat exchange effect also leads to large temperature deviations at some temperature measurement locations, which in turn leads to inaccurate measurement data and affects the operation of the staff. The use of one-way liquid inlet will easily lead to uneven heat transfer in local areas of the heat exchanger, which not only reduces the heat transfer efficiency, but also increases energy consumption
