Problems solved by technology

[0004] Most of the reactors used in solid-liquid two-phase reaction systems have only a single outlet and cannot achieve solid-liquid separation
After discharging, a separate separation device is required, which not only increases the operation steps, but also increases the production cycle

Embodiment Construction

[0018] In the figure, 1. The feed port of the reactor, 2. The kettle body, 3. The steam pipeline, 4. The discharge valve, 5. The circulation pipeline control valve, 6. The membrane separator.

[0019] The steam enters the reactor through the steam pipe. The steam pipe is composed of a main pipe and 6 branch pipes. The top of the main pipe is closed, and 6 branch pipes are installed from the side. The angle between the branch pipe and the axis of the main pipe is 60°-80°. In addition, in order to prevent the reaction material from entering the pipeline after the steam stops, a floating tongue is installed at the end of the branch pipe.

[0020] The separation and circulation pipeline is connected from the bottom of the reaction kettle, and the material is pumped out by a pump, sent to the circulation pipeline, and then passed through the membrane separator. In the membrane separator, the liquid is separated through the membrane, and the remaining materials are returned to the I...

Abstract

The invention discloses a thermal reaction and membrane separation circulation coupled device and a use method thereof, which are suitable for biomass, particularly for a straw acid, neutral or weak alkali solid-liquid mixing system. The circulation coupled device comprises at least one main reactor, and is characterized by further comprising at least one steam pipeline, and the gas outlet of the steam pipeline is positioned in the reactor; and the main reactor is connected with a pump through a pipeline, the pump is connected with a membrane separation device, and the membrane separation device is connected with the reactor.

Description

technical field [0001] The invention belongs to the technical field of biochemical equipment, and in particular relates to a lignocellulosic biomass raw material pretreatment device and a pretreatment method, in particular to the pretreatment of agricultural straw. Background technique [0002] Reactors are widely used in the chemical industry, and acidic reaction systems require an acid-resistant lining on the inner wall of the reaction. In addition, some reactors use jacket heating, built-in coil heating, etc., especially when the reactant system can be in direct contact with hot materials (steam), which will complicate the structure of the reactor, increase equipment costs, and The built-in snake pipe is difficult to clean. [0003] If the reactor is operated intermittently, feeding in batches and discharging in batches, the biggest disadvantage is that the production cycle is long, especially when the reaction temperature is high, it takes a certain amount of time to he...
