Problems solved by technology

[0002] Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, food, pressure vessels used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes, such as reactors, reaction pots, decomposition pots , polymerization kettle, etc.; materials generally include carbon-manganese steel, stainless steel, zirconium, nickel-based alloys, and other composite materials. The broad understanding of the reactor is a stainless steel container with physical or chemical reactions. The structural design of the container is carried out according to different process conditions. However, most of the reactors currently on the market have complex structures and high costs, and are not practical for small fluidized bed reactions. Therefore, a new solution is urgently needed to solve the above technical problems

Embodiment 1

[0014] see figure 1 , a new detection reactor, the reactor includes a reactor body 3, a cyclone separator 2 is arranged on the reactor body 3, a heat exchange assembly and an internal component 5 are arranged in the middle of the reactor body, the The bottom of the reactor body is provided with a discharge port 6 and a gas distribution device. The heat exchange assembly includes a tubular heat exchanger 4 and a box heat exchanger 8, and the tubular heat exchanger is symmetrically distributed on the reactor body. The box-type heat exchanger is set as the bottom in the middle of the reactor body, and the gas distribution device 7 is set as one of side flow distribution plate, sieve plate type distribution plate or packing type distribution plate. The side flow type distribution plate, the sieve plate type distribution plate or the packing type distribution plate described in this technical solution can make the gas distribution more uniform, and will not cause channeling, no lea...

Embodiment 2

[0016] see figure 1 , as an improvement of the present invention, the reactor body includes a top cover 31, a cylinder body 32 and a bottom cover 33, the cylinder body 32 is set in a cylindrical shape, the top cover 31 is set in an oval shape, the The bottom cover 33 is configured in a conical shape. In this technical solution, the upper part of the body is a gas-solid separation space, and its diameter is often larger than that of the cylinder, and a gas-solid separation device is installed inside. The middle part of the body is the basic space for fluidization and reaction, and the bottom part of the body is the gas The distribution space is equipped with gas distribution devices. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0018] see figure 1 , as an improvement of the present invention, the internal component 5 is set as a louvered baffle. When the flow rate is low, louver-type baffles can be used to improve the contact between the gas-solid two-phase in the bed, reduce axial back-mixing, improve fluidization quality and high reaction efficiency, and reduce the height of the fluidized bed. The carry-out of particles is reduced, and the rest of the structure and advantages are exactly the same as in Example 1.

Abstract

The invention relates to a novel detection reactor. The novel detection reactor is characterized by comprising a reactor body; the reactor body is provided with a cyclone separator, a heat exchange assembly and an internal part are arranged in the middle of the reactor body, and the lower portion of the reactor body is provided with a discharging opening and a gas distribution device; the gas distribution device is a lateral flowing type distribution plate or a sieve plate type distribution plate or a filler type distribution plate; the heat exchange assembly comprises tubular heat exchangers and a box-type exchanger. The tubular heat exchangers are symmetrically distributed on the two sides of the reactor body, the box-type exchanger is arranged at the bottom of the middle of the reactor body, and the heat exchange assembly has the effects of supplying and removing heat to enable a reaction to be carried out within a reasonable temperature range. According to the technical scheme, as the tubular heat exchangers and the box-type exchanger are arranged at the same time, heat exchange efficiency is improved. The integral structural design is compact and ingenious, and conversion efficiency is greatly improved.
