Problems solved by technology

[0006] At present, domestic research work on such by-product resources is relatively low. Most domestic enterprises adopt methods such as incineration and sanitary landfill, and small and medium-sized enterprises even dump them in the open air. These treatment methods lack effective high-value utilization. way

Embodiment 1

[0054] The biomass waste used in the cellulose industrial biomass waste processing method provided in this example is distiller's grains, a by-product of the solid-state fermentation process, with a moisture content of 55-65%. The content is 66-74%, the fixed carbon content is 15-20%, and the ash content is 10-15%.

[0055] The process operation of its riser reactor adopts the mode of activation reaction, and the process method is to prepare porous carbon material as the target product. The process flow is as follows figure 1 As shown, wherein, the reference signs are as follows:

[0056] 1 raw material inlet 2 dryer

[0057] 3 Gas-solid separator inlet 4 Dry raw material gas-solid separator

[0058] 5 Gas phase outlet of separator 6 Raw material inlet of carbonization reactor

[0059] 7 Carbonization reactor air inlet 8 Carbonization reactor

[0060] 9 carbonized product separator 10 volatile matter outlet

[0061] 11 Gas inlet 12 Hot blast stove tuyeres

[0062] 13 Hot...

Embodiment 2

[0084] The processing method of the cellulose industrial biomass waste implemented by the present invention does not need to change the technological process of the unit equipment, only needs to adjust its operating conditions, and can flexibly switch the target product of the processing method, and its technological process is as follows figure 2 shown. The difference between this example and Example 1 is that the treatment mode of the pyrolysis carbonization intermediate product is to blow oxidative medium and gasification agent into the riser reactor, so that the pyrolysis carbonization intermediate product is in the oxidative medium and gasification agent. The gasification reaction occurs under the combined action of the gas, and the synthesis gas (that is, biomass gas) is prepared. The oxidizing medium used in the process is oxygen, the temperature of the system is maintained at 1000-1200 ° C, and the gasification agent used is water vapor.

Embodiment 3

[0086] Another treatment mode of the pyrolysis carbonization intermediate product in this embodiment is to completely burn the pyrolysis carbonization intermediate product by blowing an oxidizing medium into the riser reactor, and the temperature of the generated flue gas is 800-1000°C. It is used to prepare steam for external supply, and its technological process is as attached image 3 shown.

Abstract

The invention discloses a processing method and a process device of cellulose industrial biomass wastes, and the method comprises the following steps: feeding raw materials into a drying system continuously, supplying heat by high-temperature flue gas from the combustion of volatile matter precipitated in pyrolysis and carbonization so as to dry the raw materials; allowing the dried raw materials to enter a carbonization reactor for pyrolysis and carbonization, delivering the intermediate products of pyrolysis and carbonization to a riser reactor, preparing porous carbon-based adsorption functional material (namely active carbon), syngas (or called biomass gas), or steam under the action of an oxidative medium and an activator, or an oxidative medium and an gasifying agent, or an oxidative medium. The steam required by the system is prepared by the activated or gasified high-temperature gas-solid products through heat exchange, which can increase the energy recovery efficiency of the process; the process adopts a continuous running mode with complete self-heating, and realizes the high-value conversion of cellulose industrial biomass wastes.

Description

technical field [0001] The invention belongs to the technical field of utilization of biomass resources, and relates to a processing method for the clean conversion and optimal utilization of biomass in the cellulose industry, specifically a method for integrating raw material drying, pyrolysis carbonization, and activation to produce porous carbon materials / gasification to synthesis The invention relates to a continuous processing method and device for the continuous processing of cellulose industrial biomass produced by gas / combustion into steam. Background technique [0002] In recent years, with the rapid development of the social economy, the contradiction between the rapid increase in the demand for fossil energy and the gradual shrinking of the actual supply in various countries has become increasingly prominent. 2 The environmental problem that the gas causes the greenhouse effect to intensify has attracted the attention of people from all walks of life. Biomass is ...
