Abstract
The utility model provides a new energy-efficient blast furnace coal dust jetting tube, including a carrier pipe connected to an end of a three-way tube. The other two ends of the three-way tube connect respectively to a steam pipe and a coal dust pipe. The carrier pipe connected to an end of a flexible pipe is mounted with a magnetizer. The other end of the flexible pipe connects to an end of the coal dust jetting pipe. The other end of the coal dust jetting pipe connects to a coal dust jetting nozzle. The utility model boosts thermal efficiency because the coal burns more sufficiently, thereby having a better energy saving effect.
Description
Technical field
The utility model relates to the smelting equipment annex, is a kind of novel energy-conserving pulverized coal injection tube cell.
Background technology
The coal powder jetting tube that uses on the iron-smelting blast furnace has multiple structure, but all has energy-saving effect and the not good enough deficiency of thermo-efficiency.This area once had report to attempt the structure of coal powder jetting tube is made improvement, to improve the burning of coal value, the sealing of coal powder jetting tube reaches and the connectivity problem of other parts but owing to can't solve, so far can not apply, so the coal powder jetting tube major part of using on each iron-smelting blast furnace is still continued to use traditional coal powder jetting tube at present.
Summary of the invention
The purpose of this utility model is, a kind of novel energy-conserving pulverized coal injection tube cell is provided, and it can improve thermo-efficiency, makes burning of coal more abundant, has energy-saving effect etc. preferably.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of novel energy-conserving pulverized coal injection tube cell, comprise transfer lime, transfer lime is connected with Y-tube one end, Y-tube is connected with coal pipe with vapour pipe respectively at two ends in addition, and magnetizing apparatus is installed on the transfer lime, and transfer lime is connected with flexible pipe one end, the flexible pipe the other end is connected with coal powder jetting tube one end, and the coal powder jetting tube the other end is connected with the Coal powder spray shower nozzle.Clamp-on holder is installed on the coal powder jetting tube.Clamp-on holder has sealing gland, and sealing gland is connected with sealing grip tube one end, and the sealing grip tube the other end is connected with the joint base.Between sealing gland and sealing grip tube, high temperature resistant asbestos pad is installed.The Coal powder spray shower nozzle is a tantalum pipe shower nozzle.
The utility model draws following advantage through overtesting: mix with coal dust by steam, and make the coal dust magnetization, coal can fully be burnt, thermo-efficiency improves a lot, and energy-conservation total amount is generally about 20-30%.Prolong 3-4 the work-ing life of shower nozzle doubly, installation and use are all more convenient etc.
Description of drawings
Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is I portion structure for amplifying synoptic diagram in the accompanying drawing 1, mainly illustrates the structure of clamp-on holder 10.
Embodiment
5 is transfer limes among the figure, transfer lime 5 is connected with Y-tube 3 one ends, Y-tube 3 two ends in addition is connected with coal pipe 2 with vapour pipe 1 respectively, magnetizing apparatus 4 is installed on the transfer lime 5, transfer lime 5 is connected with flexible pipe 7 one ends, flexible pipe 7 the other ends are connected with coal powder jetting tube 9 one ends, and coal powder jetting tube 9 the other ends are connected with Coal powder spray shower nozzle 11.Clamp-on holder 10 is installed on the coal powder jetting tube 9.Clamp-on holder 10 has sealing gland 16, and sealing gland 16 is connected with sealing grip tube 14 1 ends, and sealing grip tube 14 the other ends are connected with joint base 12.Between sealing gland 16 and sealing grip tube 14, high temperature resistant asbestos pad 15 is installed.Coal powder spray shower nozzle 11 is tantalum pipe shower nozzles.Clamp-on holder 10 described in the utility model is fixed on the furnace wall of blast furnace in use, is convenient to make coal powder jetting tube 9 and Coal powder spray shower nozzle 11 works better in blast furnace.The clamp-on holder 10 of the utility model design have connect fast, good airproof performance and use competent advantage.Clamp-on holder 10 when mounted, earlier joint base 12 is connected with blast furnace furnace wall, reinstall high temperature resistant pad 13, high temperature resistant asbestos pad 15 and sealing gland 16, be connected with sealing grip tube 14 then, sealing grip tube 14, high temperature resistant asbestos pad 15 and sealing gland 16 are connected with joint base 12 angle dentition formula grooves.6 is valves among the figure, the 8th, and valve.
