Abstract
The utility model discloses an active carbon, lime hydrate closed loop feeding system for the useless tail gas purification that burns of danger handles. The materials are sent into a low-temperature flue gas dry reaction tower by high-pressure air blown out by a Roots blower, so that heavy metals and dioxin in the flue gas are adsorbed, acidic substances in the flue gas are neutralized, and the aim of purifying the flue gas is fulfilled. The method comprises the following steps: the device comprises a collecting hopper, a transmitter and a Roots blower; the slaked lime or the activated carbon is sent into the dry reaction tower through a transmitter under the action of a Roots blower, the outlet of the collecting hopper is connected with the inlet of the transmitter, and the transmitter is connected with the dry reaction tower through a pipeline and a regulating valve; and the inlet of the Roots blower is connected with the outlet flue of the induced draft fan, and the outlet of the Roots blower is connected with the inlet of the transmitter.
Description
Technical Field
The utility model belongs to the industrial waste treatment field, concretely relates to active carbon, lime hydrate closed loop feeding system.
Background
In the existing purification treatment process of hazardous waste incineration tail gas, after low-temperature flue gas enters a dry reaction tower, slaked lime and activated carbon are sprayed into the tower and are used for adsorbing dioxin in the flue gas and neutralizing acid substances in the flue gas, so that the aim of purifying the flue gas is achieved, and usually, a power source of a feeder is from air, so that the oxygen content in the flue gas is easily increased, and the standard-reaching emission of the flue gas is not facilitated.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an active carbon, lime hydrate closed loop feeding system, the high-pressure wind that the material blew off through roots's fan send into low temperature flue gas dry-type reaction tower with lime hydrate or active carbon, adsorb heavy metal and dioxin in the flue gas, and the acidic material in the while and the flue gas reaches the purification flue gas purpose.
The feeding system comprises: the device comprises a collecting hopper, a transmitter and a Roots blower; the slaked lime or the activated carbon is sent into the dry reaction tower through a transmitter under the action of a Roots blower, the outlet of the collecting hopper is connected with the inlet of the transmitter, and the transmitter is connected with the dry reaction tower through a pipeline and a regulating valve; and the inlet of the Roots blower is connected with the outlet flue of the induced draft fan, and the outlet of the Roots blower is connected with the inlet of the transmitter.
The feeding system adopts the outlet flue gas of the induced draft fan as feeding power, does not increase the oxygen content of the incineration system, and improves the flue gas emission index.
Drawings
Fig. 1 is a schematic diagram of the system according to the present invention.
Detailed Description
The invention is further described with reference to the following specific drawings and examples.
Examples
An active carbon, lime hydrate closed loop feeding system, includes: the collecting hopper 1, the sender 3 and the Roots blower 9; the outlet of the collecting hopper 2 is connected with the inlet of a transmitter 3, and the transmitter 3 is connected with a dry reaction tower 4 through a pipeline and a regulating valve; and the inlet of the Roots blower 9 is connected with the outlet flue of the induced draft fan 6, and the outlet of the Roots blower 9 is connected with the inlet of the transmitter 3. Adding slaked lime or activated carbon into a collecting hopper 2, introducing a transmitter 3, and sending the mixture into a dry reaction tower 4 under the action of high-pressure airflow; the whole feeding system forms a closed system, and the purified flue gas is used as an air source of the Roots blower, so that the outside air is prevented from entering the flue gas purification system, and the emission quality of the flue gas is improved.
