Highly effective slurry phase bed reactor

Abstract

The invention relates to a high-efficiency slurry bed reactor, which belongs to the field of chemical machinery. It mainly consists of a solid-liquid separator, a variable-diameter inner sleeve, a reactor jacket, a heat exchanger with internal components, a gas riser with nozzles, an inner sleeve with heating and gas distribution functions, anti-blocking nozzles, nozzle mounting plates, Heat exchanger, heating coil outlet, secondary distribution plate, heating coil, etc. The beneficial effects of the present invention are that the distributor of the reactor is not easily blocked, the gas-liquid mixing is uniform, the gas-solid contact is sufficient, the reaction efficiency is high, the carrying amount of the catalyst and the solvent is small, the bias flow, channel flow and dead bed are not easy to occur, and the slurry flow rate Fast, the viscosity of the slurry in the reactor is basically the same, and the heat of reaction can be removed in time, especially in the stage of catalyst reduction and temperature rise, it is easy to realize the stable operation of the reactor. In addition, the distribution of the feed gas in the reactor along the axial direction is basically the same as the concentration of the catalyst. The catalyst can maximize its reactivity, and the space of the reactor can be fully utilized.

Description

1. Technical field [0001] The invention relates to a slurry bed reactor suitable for producing chemicals such as dimethyl ether and methanol, belonging to the field of chemical machinery. 2. Background technology [0002] Slurry bed reactor is a new type of chemical reaction equipment. It uses raw material gas as the power source of reaction mixing, uses inert solvent as the carrier, and disperses and suspends the catalyst in the solvent for reaction. This type of reaction equipment has no mechanical Stirring, so it can run leak-free at high temperature and pressure. Since the inert solvent is used as the carrier of the dispersed catalyst, the heat capacity is large, which is conducive to the stability of the reaction temperature. Due to the strong disturbance of the gas in the bed, the heat of reaction can be removed in time, avoiding hot spots in the bed and prolonging the life of the catalyst. . The existing slurry bed reactor is often blocked due to the restriction of ...
