Abstract

The invention discloses an integral oil bath type pipeline reactor and a realization method thereof. The integral oil bath type pipeline reactor comprises an expansion tank, an oil guide pipe, an oil tank heat-insulation layer, an oil storage tank, a heating pipe, a reaction pipe, a reaction pipe bracket, an oil tank transverse flow pump, an oil tank transverse flow pump driving motor, an oil tank transverse flow pump magnetic driver and heat-conducting oil, wherein the expansion tank is communicated with the oil storage tank through the oil guide pipe; the oil tank heat-insulation layer covers the oil storage tank; and the oil storage tank is fully filled with the heat-conducting oil. The integral oil bath type pipeline reactor disclosed by the invention adopts an integral design, and heating, heat transferring and heat utilization are integrated, so that surplus pipelines and flange connecting pieces are prevented from being additionally arranged and the size is reduced; and the square design is adopted so that the heat-insulation layer is easy to manufacture, the heat loss is few and the whole energy consumption is low.

Description

technical field [0001] The invention relates to the field of pipeline reactors, in particular to an integral oil-bath pipeline reactor and a realization method thereof. Background technique [0002] The pipe reactor is mainly used in the continuous reaction process of gas phase, liquid phase and gas-liquid phase. It consists of a single (straight tube or coil) continuous or multiple parallel tubes. It is generally equipped with casing or shell-and-tube heat exchange. device. During operation, the material is continuously added from one end, reacts continuously in the tube, and flows out from the other end continuously, thus reaching the required conversion rate. This kind of reactor has the advantages of small volume, large specific surface, less back-mixing, continuous change of reaction mixture, and easy control. As chemical production tends to be more and more large-scale, continuous, automated, and continuously operated pipeline reactors are used more and more in the p...

Problems solved by technology

Chinese Patent Publication No. CN102553512A and Chinese Patent Publication No. CN103349950A are all examples of pipeline reactors. Their common disadvantage is that the heat carrier of the reaction pipeline needs to be provided by additional equipment. The heat carrier is generally heat transfer oil, and the equipment is generally a heat transfer oil furnace. The heat-conducting oil furnace heats the heat-conducting oil, transports it to the casing layer of the reaction tube or the interlayer of the container through the pipeline, and then returns to the heat-conducting oil furnace for circulation

The above-mentioned working method produces the following problems: (1) heat separation for heating and transmission will produce a lot of pipes, flange connectors, etc. The technology is difficult, and its energy consumption is also very large; (2) The heat transfer oil furnace must generally be equipped with a heat transfer oil circulation pump. The heat transfer oil circulation pump works under high temperature and high pressure, and its sealing and cooling are difficult to achieve good results. , and its purchase and maintenance costs are also relatively high; (3) the flow of heat transfer oil in the reaction tube casing layer or container interlayer depends on the pressure of the pump to flow and circulate. Due to the scientific design, it is inevitable that there will be problems of flow dead zone, circulation and mixed flow, which will cause the problem of uneven temperature of the reaction tube
