Embodiment 1

[0026] Crush 55 kg of coke powder, 15 kg of coking coal and 5 kg of anthracite into coal powder with more than 90% passing through a 200-mesh screen, heat and melt the pitch, stir it evenly, and keep it warm for later use; add molten pitch to the coal powder, the amount Add 10 parts by weight for every 100 parts by weight of coal powder. After kneading evenly, send it to a double-roll molding machine with a pressure of 50.0 MPa, and press it into φ10mm spherical particles; then send the spherical particles to a carbonization furnace at 750°C for carbonization After hours, the carbonized material is made into carbonized material; then the carbonized material is sent into a vertical activation furnace, and activated with 0.25MPa water vapor at 950°C for 4 hours to make a dual-purpose activated coke product for flue gas treatment and water source purification.

Embodiment 2

[0028] Crush 60 kg of carbonized powder, 25 kg of 1 / 3 coking coal, and 10 kg of bituminous coal into pulverized coal that can pass through a 200-mesh sieve for more than 90%, heat, melt, mix pitch and tar at a ratio of 20:80, and stir evenly Insulation for standby; add the mixture of molten pitch and tar to the coal powder, the addition amount is 25 parts by weight for every 100 parts by weight of coal powder, after kneading evenly, send it to the double-roll forming machine with a pressure of 180.0MPa, and press it into φ11 ×8mm apricot core-shaped particles; then put the apricot core-shaped particles into a carbonization furnace at 800°C and carbonize for 1.5 hours to make carbonized material; then send the carbonized material into a vertical activation furnace at 980°C with 0.6 Activated by MPa water vapor for 12 hours to make dual-purpose activated coke products for flue gas control and water source purification.

Embodiment 3

[0030] 65 kg of pulverized coal, 30 kg of coking coal and 15 kg of anthracite are respectively crushed into pulverized coal that more than 90% can pass through a 200-mesh sieve, and the asphalt and tar are heated, melted and mixed in a ratio of 30:70, stirred evenly, and kept warm for later use; Add a mixture of molten pitch and tar to the pulverized coal in an amount of 30 parts by weight for every 100 parts by weight of pulverized coal. After kneading evenly, send it to a double-roll molding machine with a pressure of 300.0MPa, and press it into φ13×11×8mm Olive-shaped particles; then send the spherical particles into a carbonization furnace at 780°C, and carbonize for 1.5 hours to make carbonized material; then send the carbonized material into a vertical activation furnace, and activate it with 0.5MPa water vapor at 1050°C for 20 Hours, to make dual-purpose activated coke products for flue gas control and water source purification.

Abstract

The present invention provides a preparing method of active coke for gas purification and water source purification, including following steps: 1) preparing coal powder, breaking raw material to coal powder which more than 90% can pass 200 mesh sieve; 2) preparing an adhesive, keeping warm after heating melt asphalt or mixer of asphalt and tar, evenly mixing; 3)adding the adhesive to coal powder, forming pelleting, charing, activation and sieving package after mixing evenly. The preparing method and its product have gas-liquid dual efficacies, further reduces cost and simple process, preparation by make the most of present equipment, do not large change equipment; the prepared product has better dynamic purifying effect, realizes desulfurization, denitration, demercuration and dechlorination, removing dioxin and dust removing integrated purifying functions; the prepared product saves water, electricity and location in the pratica; application of the gas desulfurization, also a lower investment, the source is recycled in the treating process, this can not cause secondary pollution.

Description

technical field [0001] The invention relates to a preparation method of activated coke, that is, activated carbon and its product, in particular to a preparation method and product of dual-purpose activated coke which can control flue gas and purify water source. Background technique [0002] This application is a series of applications of the same applicant: the application 200510132628.8 "Preparation method of active coke for flue gas treatment and the prepared active coke for flue gas treatment" submitted by the applicant on December 13, 2005 discloses a flue gas treatment The preparation method of activated coke and the prepared active coke for flue gas treatment, wherein the cost of the prepared flue gas treatment active coke is relatively low, and the desulfurization and denitrification effect of the prepared flue gas treatment active coke is improved; the stacking weight increases under the same volume (volume) ; Good strength, not easy to wear; Long service life.
