Abstract
The invention discloses an OuYe furnace drying device. The drying device comprises a thermocouple, induced air pipes, an air mixing pipe and gas eduction pipes. The air mixing pipe is vertically arranged. The thermocouple is mounted in the air mixing pipe. The induced air pipes are uniformly connected to the upper end of the air mixing pipe at intervals in central symmetry. A horizontal flow guide plate is horizontally arranged at the lower end of the air mixing pipe. Flow guide grooves are uniformly distributed in the bottom face of the flow guide plate at intervals in central symmetry. A big octagonal coiled pipe and a small octagonal coiled pipe are arranged in the top face of the horizontal flow guide plate from inside to outside in a spaced mode and communicate with each other. The pipe wall of the big octagonal coiled pipe and the pipe wall of the small octagonal coiled pipe are each provided with four rows of holes horizontally from top to bottom. Every two adjacent rows of the holes are spaced by 60-100 mm. The spacing of every two adjacent holes of the same row is 80 mm. The aperture of each hole is 15 mm. The two gas eduction pipes are connected to the top faces of the two sides of the big coiled pipe correspondingly.
Description
Technical field
The present invention relates to a kind of Ou Ye baking oven furnace apparatus.
Background technology
Tradition blast furnace ironmaking must have the coke of abundance.The coking coal resource being currently used for coking only accounts for about the 10% of whole coal resources, can only supply the usage amount of ironmaking about 20 years.After 20 years, tradition blast furnace ironmaking flow process will face the crisis of coking coal resource shortage.In order to tackle the coking coal resource crisis that i.e. will appear from, people succeed in developing Ou Ye stove ironmaking technology on the plinth of VAI COREX Technology.Ou Yelu must complete baker work before blow-on, traditional Ou Ye baking oven technique is before baker, baker lower tube and resistance to material is laid bottom cupola well, and add pig and electrode as the basic thermal source of cupola well preheating during blow-on, the most burnt and middle granularity coke is gradually added basic as cupola well accumulation of heat above electrode, and must blow-on immediately after baker.Open that baker process cost is high, risk is big.
Summary of the invention
It is an object of the invention to provide a kind of Ou Ye baking oven furnace apparatus, it is possible to be effectively reduced baker cost, reduce baker risk.
nullThe object of the present invention is achieved like this，A kind of Ou Ye baking oven furnace apparatus，Including thermocouple、Induced duct、Mixing wind tube and gas export control，Described mixing wind tube is vertically arranged，The installation of TC is in mixing wind tube，The uniform interval that is centrosymmetric, mixing wind tube upper end is connected to some induced ducts，Mixing wind tube lower end horizontally disposed one piece of horizontal deflector，The uniform interval that is centrosymmetric on deflector bottom surface arranges guiding gutter，On horizontal deflector end face, interval arranges two octagonal coil pipes of size from inside to outside，Two octagonal coil pipes are interconnected，Four rounds the most all it are horizontally disposed with on the tube wall of two octagonal coil pipes，At a distance of 60 100mm between every round，The adjacent holes spacing of same round is 80mm，Aperture, each hole is 15mm，A gas export control is respectively connected on the both sides end face of big coils.
When the present invention uses, heat smoke that during baker, the outer baker dolly of stove provides and with addition of cold wind be introduced into center mixing wind tube, temperature is monitored built with thermocouple at mixing wind tube, by adjusting cold wind with addition of amount, the final temperature controlled in mixing wind tube is to target temperature, mixing enters below the deflector bottom furnace bottom to the flue gas of target temperature through mixing wind tube, realize heat smoke and can be uniformly dispersed in furnace bottom under baffle at bottom, furnace bottom is carried out Baking out, and finally after deflector edge flows out, enters gasification furnace by octagonal coil pipe.
Anistree coil pipe is arranged on baffle at bottom.Its effect has 2 points, first it is during baker, the a part of baker heat smoke entering gasification furnace enters anistree coil pipe through the aperture of anistree coil pipe, then the gas export control through docking mutually with anistree coil pipe causes outside stove, it is achieved the baking to the body of heater resistance to material of ferrum port area.Another some effect is as gas export control during blow-on.Realize safe blow-on.
Can be even into for guaranteeing to enter the heat smoke of anistree coil pipe, in anistree coil pipe middle and lower part, parallel four line spaces of having opened are 60 100mm, and aperture is the aperture of 15mm.The uniform derivation of heat smoke can be realized, can prevent again large granular materials from entering delivery line and cause delivery line to block.
This furnace drying device by the heat smoke produced outside stove and with addition of cold wind after mixing wind tube uniformly mixes, enter back into furnace bottom material resistance to furnace bottom to toast, having temperature adjusting simple to operate, apparatus structure is simple, feature easy for installation, and resistance to material bottom cupola well can be realized uniformly heat up, solve a difficult problem for baker before Ou Ye stove blow-on, with VAI company of Siemens exploitation have graphitic carbon roast technic compared with, operate more flexible, expense is lower, and once opening baker process saving expense has more than 13,000,000 yuan.Remarkable in economical benefits.
