Abstract

The invention relates to activated carbon regeneration and in particular relates to an electro-thermal regeneration method of activated carbon. In the method, by virtue of the electrical conductivity and electrical resistance of the activated carbon, electrode plates are arranged at two sides of a box loaded with the activated carbon so as to heat the activated carbon.

Description

A kind of method of active carbon heating

Technical field

The present invention relates to a kind of active carbon regeneration, particularly relate to a kind of method by the regeneration of electrical heating active carbon.

Background technology

Active carbon has unique pore structure and surface functionalities, enough chemical stability, mechanical strength and performance such as acidproof, alkaline-resisting, heat-resisting; be widely used in fields such as three industrial wastes improvement, solvent recovery, food and drink purification, carrier, medicine, gold extraction, semiconductor application, battery and electric energy storage; along with the attention of China for environmental protection, the active carbon desulfurization denitration technology has occupied certain market.Because activated carbon dosage is big, price is high relatively, so the regeneration of active carbon is key wherein.Currently used regeneration techniques generally has two kinds: the one, utilize natural gas heated inert gas after, feed in the active carbon.This method equipment complexity, heat time heating time is long, and the active carbon reproduction speed is slow; The 2nd, utilize heating rod that active carbon is contacted outer heating.This method equipment complexity, the energy consumption height, heating is slow.

Summary of the invention

The objective of the invention is at the deficiencies in the prior art, the Fast Heating that a kind of energy consumption is low, pollution is little, production cost is low process of active carbon is provided.

The technical scheme that realizes the object of the invention is: utilize the electric conductivity and the self-resistance of active carbon itself, be furnished with battery lead plate in the casing both sides that active carbon is housed and carry out the inner heating of active carbon.

The good effect that the present invention has: the electrical heating active carbon generates heat from inside to outside by the active carbon self-conductive, has reduced heat propagation to the scattering and disappearing of heat, and the energy transformation ratio height plays energy-saving and cost-reducing effect.Simultaneously, this method is simple to operate, and heat time heating time is short.This method fast 1 hour/ton than natural gas heated inert gas method is than electrical bar heating power saving 120 degree/tons.This promotes the use for the active carbon desulfurization denitration technology, environmental quality raising positive impetus is arranged.

The specific embodiment

Embodiment 1

The thermal regeneration method of the active carbon of present embodiment has as follows:

Present embodiment is to constitute (seeing accompanying drawing) by 380V power supply, steel current conducting plate (1), insulation ceramic tiles (5), insulation barrier.

15 bags * the 25Kg of active carbon that this method adopts, two battery lead plates are that 2m(is long) * the 1.5m(height) * 0.008m(is thick) steel plate (1), pole plate is 1m at interval.Heating power supply is two in the 380V power line, and conductive cable is No. 35 electrode holder lines.The electric wire two ends have the ammeter (3) of a 100A respectively, and the air switch (7) of a kilowatt-hour meter (6) and a 100A is arranged on total circuit.

1. it is long to make two 2m() * the 1.5m(height) * 0.008m(is thick) steel plate (1) as battery lead plate;

2. it is long to lay 2.5m(with insulation ceramic tiles (5) on the ground) * 1.5m(is wide) the plane, guarantee leakproof, the battery lead plate of making 1. is upright thereon, fix;

3. the pole plate two ends use insulated ceramic plates (8) to bottle up equally, flow out to prevent active carbon (4);

4. ZL-50 type the active carbon with 15 bags * 25kg falls in the middle of two pole plates leveling.Simultaneously thermocouple is embedded in the active carbon, measures temperature;

5. on two pole plates, insert two in three of the 380V power lines, on power line, insert ammeter simultaneously, measure power consumption.

Power turn-on gets final product powered-down when the active carbon temperature is elevated to 300 ℃, record power consumption.

Result of the test is as follows:

Quality of activated carbon: 0.375 ton of final temperature: 300 ℃

?	1	2	3
				Initial temperature (℃)	22	13	22
Time (min)	53	52	43
				Power consumption (during kw)	27	31	26

Claims

1. the method for active carbon heating, its feature is regenerated by current flow heats at active carbon.
