Embodiment Construction

[0015] As shown in the drawings: Extrusion-type high-pressure heating coal coking extraction process is to send the raw coal into the feed port of the screw-type high-pressure extruder through the conveying device, and pass through the high-pressure extruder (the working pressure of the equipment is generally 50-60 tons) ) extruded briquettes into the forming section, during the high-pressure extrusion process, the coal generates a certain amount of heat under the action of high pressure, and then the briquettes are heated to 750-850 degrees for 10-15 minutes in the forming section, and the formed raw coal is heated at high temperature A chemical change occurs into coke, and the coke heated in the molding section is sent to the extraction section, and the gas and coal tar in the coke are extracted in the extraction section, and the gas and coal tar extracted in the extraction section enter the storage device and are extracted. The coke extracted in the workshop section is sent ...

Abstract

An extraction of extrusion high-pressure warm-up coal coking is carried out by delivering raw coal into feed inlet of high-pressure extruder by conveyor, entering extruded sectional coal into formation section, heating to 750-850 deg. C for 10-15 mins, delivering coke into extraction section, extracting gas and coal tar from coke, entering them into storage apparatus, delivering extracted coke into coke cooling tank and delivering cooled coke into finished-parts store house. It costs low, occupies less area, has less discharge heat energy and no environmental pollution and saves energy recourses.

Description

1. Technical field [0001] The invention relates to a coal coking process, which is an extrusion-type high-pressure heating coal coking extraction process. It is suitable for coal coking and extraction of coal tar and gas. 2. Background technology [0002] At present, the existing coal coking is coke oven coking. This coking method not only occupies a large area, requires a large investment in equipment, but also has high requirements on the quality of raw coal. It also emits a lot of heat, pollutes the environment, and wastes energy. 3. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an extrusion-type high-pressure heating with a small footprint, low investment in equipment, low requirements on the coal quality of raw coal, less heat discharge, energy saving, and no pollution to the environment. Coal coking extraction process. [0004] The purpose of the present invention can be realized...
