The hydrogenation reactor device is designed with gas feed unit, liquid feed unit, reactor unit and acquisition unit.
The raw gas and raw liquid are mixed and preheated in a certain proportion and then enter the fixed bed reactor. The raw gas and raw gas are homogeneous and measured by the flow controller,
The raw material liquid is measured by the metering pump, and the reactor is heated by a three-stage electric heating furnace. After the reaction products come out of the reactor, the gas-liquid separation is carried out first,
The liquid material enters the liquid storage tank, and the tail gas is filtered and drained or connected to the on-line analyzer. Hydrogenation kettle is a kind of reaction kettle used for experiments in the laboratory,
It is suitable for precise chemical synthesis reaction experiments in which inert gas, pressure, conductivity and redox potential are added and temperature and chemical reaction are measured at the same time.
The device is a production and test equipment integrating reactor, reaction condition control system, raw material feeding and product output system.
The temperature control of the hydrogenation reactor is controlled by the temperature change of the heat transfer oil in the jacket of the hydrogenation reactor,
The more heat conducting medium in the system, the less effective power is used in the reactor, and the slower the temperature control speed is.
The liquid circulation of the whole system of hydrogenation reactor is closed. There is an expansion vessel in the system, and the expansion vessel and liquid circulation are insulated,
It does not participate in liquid circulation and has only one mechanical connection. The medium of hydrogenation reactor is at high or low temperature, regardless of whether the temperature of liquid circulation is lower than 60 ℃.
The whole liquid circulation is a closed system, which will not absorb water vapor under low temperature conditions, will not produce oil mist under high temperature conditions of hydrogenation reactor, and the working temperature range of heat transfer oil is very wide;
The same machine and the same heat transfer medium can reach the temperature control of - 100 ℃ to 200 ℃, and no mechanical and electrical valves are used in the whole circulation system.
Precautions for use of hydrogenation reactor:
During installation, check whether the connectors and transmission parts are firm and reliable, and ensure that there are no bubbles, oil leakage, oil leakage, etc.
二、The hydrogenation reactor shall be installed on a solid flat worktable, and the height of the worktable shall be determined according to the use situation,
The equipment shall have a certain space for use on the table or elsewhere, so installation and maintenance are also important.
Installation requirements: the transmission shaft is horizontal and vertical to the ground, not vertical (inclined), and the total height of the equipment shall not exceed 1 / 1000.
Hydrogenation kettle is used for catalysis, high temperature and high pressure synthesis and kinetic test. It has the advantages of numerical microscopy resistance, corrosion resistance and strong production capacity,
It is used in medicine, beverage, chemical industry, pigment, resin, scientific research and other industries.
The hydrogenation kettle is composed of kettle body, kettle cover, sleeve, agitator, transmission device, shaft seal and support.
The main materials are carbon manganese steel, stainless steel, zirconium, nickel base (Hastelloy, Monel) alloy and other composite materials;
According to the manufacturing structure of the reactor, it can be divided into open flat cover reactor, open butt welding reactor and closed reactor.
Generally, the hydrogenation reactor adopts anchor type, paddle type, turbine propulsion type or frame type mixing methods,
When the height and diameter of the mixing device are large, multi-layer mixing blades can be used, or they can be selected arbitrarily according to the user's requirements,
The sealing methods of hydrogenation reactor can be divided into packing seal, mechanical seal and magnetic seal. Electric heating is adopted for heating, and the cooling methods are casing cooling and coil cooling in the kettle.
