Description
Technical field
The invention belongs to iron making and sintering apparatus field, specially a kind of 360 degree of air-supply sintering deposit coolings of polygonal multiaspect multilayer
Tower.
Background technology
For steel production enterprise, sintering is one of technique of ironmaking production, and its process is that powdery miberal powder and coke powder are stirred
After mixing, the graininess of certain size is made by sintering machine, is smelted with facilitating.To be carried out by the sintering deposit of sintering machine cold
But, cooling is mainly realized by the air cooler of lower section.At present, the sintering deposit cooling device that iron and steel enterprise uses has belt-cooling machine
With two kinds of forms of central cooler, but Some Enterprises can not use belt-cooling machine and central cooler due to area-constrained by production scene, it is impossible to
Realize heat energy recycle and environmental protection.In order to realize heat energy recycle and environmental protection in effective site area,
Reach the purpose of energy-saving and emission-reduction synergy, polygonal 360 degree of air-supply sintering deposit cooling tower technologies of multiaspect multilayer need to be used.Such as Chinese patent
Sintering deposit cooling tower disclosed in CN10544580A, its cooling air channel is only arranged in the middle lower floor of tower using horizontally disposed, cold
But recovery structure is more complicated, and cost is higher.
The content of the invention
It is an object of the present invention to provide a kind of new 360 degree of air-supply sintering deposit cooling towers of polygonal multiaspect multilayer, to its air channel
Structure is improved, and reaches reduction windage, save electricity, reduces the purpose of production cost.
The present invention adopts the following technical scheme that realization：
A kind of 360 degree of air-supply sintering deposit cooling towers of polygonal multiaspect multilayer, including tower body, the tower body bottom are provided with dump skip, institute
State the outlet installation flashboard of dump skip and be provided with conveyer below；Dust-removing waste gas pipeline is provided with the top of the tower body, in it on
Portion is cloth dust accumulation chamber of waste gas；Middle part is provided with heat recovery pipe, the heat above dump skip in the tower body
Low temperature waste gas steam vent is distributed with energy recovery channel bottom, is set in the heat recovery pipe above low temperature waste gas steam vent
There is low temperature waste gas pipeline, the low temperature waste gas pipeline passes heat recovery pipe top, and the low temperature waste gas pipeline and heat energy return
Closed tube road top is provided with distributing device I altogether, and the distributing device I is provided with the distributing device II above low temperature waste gas pipe outlet.
Some longitudinal cooling air channels are located at around heat recovery pipe in the tower body, each longitudinal cooling air channel leads to
Cross dividing plate and be divided into multilayer independent ventiduct, middle lower floor's independent ventiduct positioned at each longitudinal cooling air channel passes through airduct I and tower respectively
External cooling blower is connected, and the upper strata independent ventiduct positioned at each longitudinal air channel passes through airduct II and taking the dish out of the pot outside tower body respectively
Stove circulation air pipe line is connected.
High temperature heat recovery air holes and installation high temperature heat recovery channel is distributed with the heat recovery pipe top, described
High temperature heat recovery channel is connected after passing tower body with entering boiler circulation air pipe line.
During work, sintering deposit is entered in cooling tower by feeding skew bridge, is distributed in after distributing device in tower.In tower
Sintering deposit in motion process from top to bottom, enter respective longitudinal cooling wind from airduct II by the circulation low temperature wind that boiler comes out
The high-rise independent ventiduct in road, the sintering deposit positioned at high temperature section is entered by its surrounding, turn into high-temperature hot-air after heat exchange heats up, lead to
Cross high temperature heat recovery air holes and enter the space between heat recovery pipe and low temperature waste gas pipeline, returned subsequently into high temperature heat
Closed tube road, last circulation again, which is passed through to boiler, to be recycled.The cooling wind entered by middle-temperature section cooling blower enters from airduct I
The middle level independent ventiduct for entering respective longitudinal cooling air channel enters the sintering deposit for being located at middle-temperature section, turns into medium temperature after heat exchange heats up
Hot blast, the space between heat recovery pipe and low temperature waste gas pipeline, Ran Houjin are entered by high temperature heat recovery air holes after rising
Enter high temperature heat recovery channel, be finally passed through to boiler and carry out heat exchange recycling.Positioned at bottom sintering deposit temperature less
Height, cooled down by the bottom independent ventiduct positioned at longitudinal cooling air channel, corresponding low-temperature end cooling blower passes through respective wind
After pipe I enters corresponding independent ventiduct, by its surrounding air-out, the high temperature sinter of surrounding is further cooled down；Due to low-temperature end
Hot blast does not have value, then low-temperature zone is not returned using waste gas by the low temperature waste gas steam vent positioned at bottom into heat energy
Duct bottom is received, the cloth dust accumulation chamber of waste gas entered after rising along low temperature waste gas pipeline at the top of tower body, passes through dust-removing waste gas
Pipeline enters deduster.
Further, in order to which the hot blast of middle-temperature section smoothly further entered into heat recovery pipe, in heat recovery pipe
Medium temperature energy recovery air holes is equally distributed with portion.
The present invention realizes polygonal 360 degree of air-supply coolings of multilayer multiaspect, because vertical air plenums design, has the following advantages that：
1st, vertical air plenums increase cooling air-out area, reduce windage, and air channel can extend into sintering deposit upper strata in tower；2、
Avoid infringement of the sintering deposit to air channel in blanking process；3rd, blown by the independent ventiduct of layering, do not increasing wind
Machine load（Do not increase power consumption）In the case of, increase air output, reduce enterprise operation cost.
The present invention is reasonable in design, have floor space is small, fetch is near, without windage loss, wind utilization rate is high, heat energy recovery rate is high,
The characteristics of good cooling results, dust are without diffusion, has the marketing application value having very much.
