In Aluminum Qinghai Branch Of An To 160ka Electrolytic Flue Gas Purification System Improvements

By the long practice of the purgative system of gaseous emissions of the 160kA reduction cell of the Qinghai branch company of Aluminum Corporation of China Limited, then the existing run status was examined carefully, The limitation of the design and the dominating problems of the existing system were summarized, and a set of finished improving project was provided in order to guide the improvement of the forthcoming purgative system of the reduction cell. At present diverse extent problems exist in the purgative system of the 160kA reduction cell of the Qinghai branch company of Aluminum Corporation of China Limited when they run, The improvement would be required as follows :(1)The gas collecting cover were setted inside the 1# and 2# reduction cell, Their structure are different partly and the insulating tube of the branch of smoking pipe on the top of the reduction cell require improvement.(2)The design of the level flue of the 1# and 2# are different greatly, The distribute of the negative pressure of the level flue is balanced by adjusting the opening angle of the papilionaceous valve of the branch of smoking pipe; The former purgative system would be improved by the numbers.(3)In order to increase the emission quantity of each reduction cell, On the base of reconstruct of the former purgative system, A new set of purgative system is setted respectively so that achieve the aim of increasing the efficiency of gas collecting, dust removing and purifying.(4) The advanced programme fashion should be adopted to design the interface on the design of the software of the purgative system of gaseous emissions of the reduction cell, striving for interface amity, operate expediently, At the same time thestorage, display, the perfect of the voice alarm function and the adjusting operation of the systemic parameter etc. should be amended greatly, so that increasing the information mutual capability wholly, and the corresponding port was provided so that netting extend of the subsequent purgative system of gaseous emissions of the reduction cell.
