specific Embodiment approach 1

[0021] like figure 1 As shown, the present invention provides a kind of activated carbon production process of zero coal consumption, and it comprises the activation process, rinsing process and finished product drying process carried out successively, it is characterized in that: described activation process is divided into following several stages and carries out:

[0022] ① Preheating and primary activation reaction: Send the carbonized carbonized raw material (such as coconut shell carbonized material) into the primary activation furnace 1 (such as horizontal rotary furnace) to preheat the carbonized raw material and conduct a primary activation reaction; the flue gas generated by the primary activation reaction is sent to the primary activation waste heat steam boiler 2 through the first flue gas delivery pipe 8-1 for heating, so that the primary activation waste heat steam Boiler 2 produces steam and sends it to the primary activation furnace 1 through the first steam de...

specific Embodiment approach 2

[0030] like figure 2As shown, the production device for the zero-coal-consumption activated carbon production process provided by the present invention, which includes activation equipment, rinsing equipment 5 and finished product drying equipment 6, is characterized in that: the activation equipment Including primary activation equipment and secondary activation equipment; said primary activation equipment includes primary activation furnace 1 and primary activation waste heat steam boiler 2, and a connection between primary activation furnace 1 and primary activation waste heat steam boiler 2 is used to discharge primary activation furnace 1 The flue gas is sent to the first flue gas delivery pipeline 8-1 of the primary activation waste heat steam boiler 2 and the first steam delivery pipeline 9-1 used to send the steam generated by the primary activation waste heat steam boiler 2 to the primary activation furnace 1 1; the secondary activation equipment includes a secondary...

Embodiment 1

[0037] Using coconut shell carbonized material as carbonized raw material, the zero coal consumption activated carbon production process is carried out in sequence according to the following steps:

[0038] ①Primary activation reaction: send the carbonized coconut shell carbonized material into the primary activation furnace 1 at a feed rate of about 0.2 tons / hour through an automatic feeder, and preheat the carbonized raw material and perform a primary activation reaction; The flue gas generated by the activation reaction is sent to the primary activation waste heat steam boiler 2 for heating through the first flue gas delivery pipe 8-1, so that the primary activation waste heat steam boiler 2 generates water vapor and sends it to the first steam delivery pipe 9-1. In the primary activation furnace 1, it is used as an activation catalyst for the primary activation reaction; the temperature of preheating and primary activation reaction is controlled around 800°C, the water vapo...

Abstract

The invention relates to a zero-coal-consumption activated carbon production process and a production device used in the process. The production device comprises activation equipment, rinsing equipment and finished product drying equipment, wherein the activation equipment comprises a primary activation equipment and a secondary activation equipment, and the primary activation equipment comprises a primary activation furnace and a primary activation waste heat steam boiler which are connected by a first smoke conveying pipeline and a first vapor conveying pipeline; and the secondary activation equipment comprises a secondary activation furnace and a secondary activation waste heat steam boiler which are connected by a second smoke conveying pipeline and a second vapor conveying pipeline, and a third smoke conveying pipeline is connected between the secondary activation waste heat steam boiler and the primary activation furnace. In the invention, the activation process of the activated carbon are divided into two steps which are sequentially carried out in two sets of activation equipment; therefore, heat generated by the activation reaction of activated carbon is fully recycled so as to realize the ' zero coal consumption' in the production process of activated coal.

Description

technical field [0001] The invention relates to the field of activated carbon production and processing, in particular to a zero-coal consumption activated carbon production process and a production device used in the process. Background technique [0002] Activated carbon manufacturing has always been considered a high energy consumption and high pollution industry. In the previous production process of activated carbon, the carbonization, activation, rinsing, and drying processes all use coal to directly heat the heat source, and the activation process is only one, which not only consumes a lot of energy, but also causes serious environmental pollution, and is prone to failure due to temperature instability. affect product quality. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a zero-coal consumption activated carbon production process and a production device for the process, w...
