Abstract

The utility model provides a glance coal clarifier that embryo production was discharged is given birth to to prebake positive pole, by an album petticoat pipe, the flue gas branch pipe, the air door, main tobacco pipe, the applying powder ware, bag collector, tuber pipe and draught fan constitute, and reasonable design, handle glance coal simple process, the device is low in operation and maintenance, high efficiency, and because the pitch part that enables in the glance coal is adsorbed back the recovery by the powdered carbon, return to the prebake positive pole and give birth to the production process of embryo, therefore can not only eliminate the prebake positive pole and give birth to the pollution of the glance coal of embryo production emission to the environment, but also help reducing the living embryo production cost of prebake positive pole, to the environmental protection, all has of great significance to practicing thrift the former material resource of this production of pitch.

Description

The raw embryo of a kind of prebaked anode produces the clarifier for exhausting asphalt smoke of discharge

Technical field

The utility model relates to a kind of gas purifier, and particularly the raw embryo of a kind of prebaked anode produces the clarifier for exhausting asphalt smoke of discharge.

Background technology

Prebaked anode is the heart of pre-baking tank aluminum electrolysis, not only as conductive electrode, electric current is imported electrolytic cell, and participate in the electrochemical reaction of alumina eltrolysis, importance is self-evident, but the production of prebaked anode, especially the production process of green compact supervenes a large amount of glance coals, not only causes severe contamination to surrounding environment, and causes this raw materials for production significant waste of pitch.At present, mostly combustion method is taked to the improvement of glance coal, the method technique is simple, the effect of administering glance coal environmental pollution still can, but there is burning glance coal and produce secondary waste gas and idle burning glance coal and do not solve prebaked anode green body and produce and produce glance coal brings waste drawback to these raw materials for production of pitch.

Summary of the invention

Technical problem to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art, and provide the raw embryo of a kind of prebaked anode to produce the clarifier for exhausting asphalt smoke of discharge, the glance coal not only contaminated environment but also the problem causing these raw materials for production of pitch to waste that produce in prebaked anode green body production process is solved with the pitch part of reclaiming in glance coal.

The technical scheme in the invention for solving the technical problem is: the raw embryo of a kind of prebaked anode produces the clarifier for exhausting asphalt smoke of discharge, it is made up of exhaust fume collecting hood, flue gas arm, air door, main smoke pipe, powder adding machine, sack cleaner, airduct and air-introduced machine, described exhaust fume collecting hood is located at the top of asphalt melting, filtration, storage and prepare burden kneading equipment and green compact forming machine, is connected with main smoke pipe by flue gas arm and the air door be arranged in flue gas arm pipeline; Described powder adding machine is arranged in main smoke pipe pipeline, opens the shell of powder input port, the unloading valve of adjustable speed and be arranged at the powdered carbon storehouse that above shell, lower discharge port connects powder input port on shell by the unloading valve of adjustable speed to form from above; And described sack cleaner, its dusty gas entrance connects main smoke pipe, and purified gas outlet is connected with the suction inlet of air-introduced machine by airduct.Such clarifier for exhausting asphalt smoke, take air-introduced machine as power, each exhaust fume collecting hood holds together poly-glance coal above the raw embryo production equipment of prebaked anode all will be inhaled into main smoke pipe by flue gas arm, powder adding machine again by arranging in main smoke pipe and main smoke pipe pipeline is sent to sack cleaner, by running into the powdered carbon added by powder adding machine during powder adding machine, asphaltum with high viscosity part in glance coal can be formed particle by powdered carbon absorption, the pitch-coating carbon granule that proportion is larger, directly ash bucket will be fallen into after entering sack cleaner, this measure one can alleviate the load of filter bag of dust collector, two viscosity that can be decreased through filter bag flue gas, alleviate compared with the attachment of fine dust on filter bag, all the filter bag cleaning cycle and service life that make sack cleaner are extended, and pass through sack cleaner, flue gas realizes gas solid separation, the gas of purification will be guided through airduct by air-introduced machine and enter smoke stack emission, the pitch-coating carbon granule collected will be recovered, return the production process of the raw embryo of prebaked anode.

The raw embryo of this prebaked anode provided by the utility model produces the clarifier for exhausting asphalt smoke of discharge, reasonable in design, process glance coal technique is simple, operation expense is low, efficiency is high, and be recovered after the pitch part in glance coal can be made to be adsorbed by powdered carbon, return the production process of the raw embryo of prebaked anode, thus can not only eliminate the raw embryo of prebaked anode and produce the glance coal of discharge to the pollution of environment, but also contribute to reducing the raw embryo production cost of prebaked anode, to environmental protection, this production raw material resources of saving pitch is all significant.
