Description
Technical field
The utility model is related to a kind of dry coke quenching auxiliary, especially a kind of dry coke quenching coke powder heat reclaim unit.
Background technology
Dry Quenching Technology is an energy-saving and environment-friendly promotional technique of coking industry, i.e. dry coke quenching is by inert circulating air
Body cools down red coke, and recycling heat produces vapor, the vapor of generation can be used for generating electricity or pressure and temperature reducing after supply other workshops
It uses, avoids a series of environmental pollutions that coke wet quenching is brought.The low-temperature circulating gas of cooling coke, coke dry quenching furnace cooling section with
Temperature is increased to 900 ~ 960 DEG C after red coke heat convection, and high temperature circulation gas comes out from the annular passage of coke dry quenching furnace, by primary
Deduster, which detaches, to be entered waste heat boiler after coarse granule coke powder and carries out heat exchange, and waste heat boiler generates steam, and temperature is down to about 160 ~
It is pre- that 180 DEG C of recyclegas is sent into water supply again through the further separate fine particles coke powder of secondary filter, after being pressurizeed by circulating fan
Hot systems are cooled to about 130 DEG C, enter back into coke dry quenching furnace and recycle.
In order to avoid the coke powder that high temperature circulation gas goes out from the carrying of coke dry quenching furnace annular passage rushes waste heat boiler boiler tube
Brush wear is equipped with disposable dust remover before high temperature circulation gas enters waste heat boiler, separates in high temperature circulation gas to pot
The relatively serious coarse granule coke powder of stove boiler tube erosive wear.The coke powder temperature separated from disposable dust remover at 900 ~ 960 DEG C,
To avoid high temperature coke powder from damaging equipment, equipped with the water cooling tube to cool exclusively for high temperature coke powder, water cooling tube is clamp sleeve noose
Structure is recycled or direct emission using water as cooling medium after water after cooling high temperature coke powder is usually cooling, not to high temperature
This partial heat of coke powder is recycled, and is unfavorable for recycling of the dry coke quenching auxiliary to red burnt sensible heat, is caused energy wave
Take.Continue to go deep into propulsion with China's energy-saving and emission-reduction work, this partial heat for recycling dry coke quenching coke powder is imperative.
Utility model content
The purpose of this utility model is to provide a kind of dry coke quenching coke powder heat reclaim unit, can recycle dry coke quenching one
The high temperature coke powder heat that secondary dedusting is separated fully recycles the sensible heat of red coke, energy saving.
The purpose of this utility model is achieved in that a kind of dry coke quenching coke powder heat reclaim unit, includes at least water cooling
Pipe, drum, desalination water source and vapour source, the water cooling tube be sleeve type structure, the water leg lower part of water cooling tube be equipped with into
The mouth of a river is equipped with water outlet on the water leg top of water cooling tube, and the inlet and outlet of water cooling tube water leg pass through pipe fitting respectively
Valve is connect with drum.
The drum is connect with desalination water source and vapour source respectively by pipe fitting valve.
Control valve is respectively equipped between drum and vapour source between the drum and desalination water source.
The water cooling tube water leg bottom is equipped with blow-off pipe, and blow-off pipe is equipped with valve；The water cooling tube water leg
Top is equipped with safety valve and exhaust pipe, and exhaust pipe is equipped with valve.
The utility model has the beneficial effects that：The high temperature coke powder heat that dry coke quenching primary dedusting is separated can be recycled
Amount, the steam of generation have not only fully recycled the sensible heat of red coke for the deoxygenation of dry coke quenching auxiliary oxygen-eliminating device or other purposes of plant area,
The energy has been saved, the energy recovery utilization ratio of dry coke quenching auxiliary has been improved, also as save production cost, generate certain economy
Benefit.

Specific implementation mode
Embodiment 1
As shown in Figure 1, a kind of dry coke quenching coke powder heat reclaim unit, includes at least water cooling tube 1, drum 8, desalination water source 9
With vapour source 10, the water cooling tube 1 is sleeve type structure, water inlet 2 is equipped in the water leg lower part of water cooling tube 1, in water cooling
The water leg top of pipe 1 is equipped with water outlet 3, the water inlet 2 and water outlet 3 of 1 water leg of water cooling tube respectively by pipe fitting valve with
Drum 8 connects.The drum of dry coke quenching residual heat boiler or the drum of plant area's other equipment nearby, drop can also be used in the drum 8
Low investment.
The drum 8 is connect with desalination water source 9 and vapour source 10 respectively by pipe fitting valve.If user is to steam quality
It is required that relatively low, it is also possible to which soft water replaces demineralized water, reduces production cost.
It advanced optimizes：Control is respectively equipped between drum 8 and vapour source 10 between the drum 8 and desalination water source 9
Valve 11 processed is adjusted outside demineralized water feedwater flow and steam by control valve 11 for flow respectively, and then uses three blunt quantity control, i.e.,
Drum 8 demineralized water feedwater flow, 8 liquid level of drum and 8 steam flow of drum these three main controlled parameters are controlled, control is reached
The purpose of 8 level stability of drum, while three blunt quantity control can find that 1 water leg demineralized water of water cooling tube is leaked into water cooling tube in time
1 coke powder channel can carry out repair and maintenance to water cooling tube 1 rapidly, avoid the generation of accident.
Further optimization：The 1 water leg bottom of water cooling tube is equipped with blow-off pipe 5, and blow-off pipe 5 is equipped with valve 7；Institute
Safety valve 4 and exhaust pipe 6 are equipped at the top of 1 water leg of water cooling tube stated, exhaust pipe 6 is equipped with valve 7.
The interval ash discharge of dry coke quenching primary dedusting generally use level-sensing device control, 1 suddenly cold and hot of water cooling tube is frequent, is unfavorable for
The long-time service and maintenance of water cooling tube 1 and the continuous and stable production of steam, it is proposed that dry coke quenching primary dedusting ash discharge follows " a small amount of more
It is secondary " principle, reduce influence of the temperature fluctuation to equipment and system to the greatest extent.
The component and structure that the present embodiment does not describe in detail belong to the well-known components and common structure or common of the industry
Means do not describe one by one here.
