Description
Technical field
The utility model belongs to chemical industry equipment and Design of Chemical Machinery and manufacturing technology field, and in particular to a kind of semicoke is cold
But device.
Background technology
In current coal chemical technology, because the semicoke temperature after high temperature pyrolysis of coal is higher, and semicoke is from reactor
Easy spontaneous combustion after discharge, semicoke carries amount of heat, seriously polluted using general ammoniacal liquor quenching waste water resource, semicoke
Quality is not also high, and using returning, dress cooling kiln cooling cost is higher, the shortcomings of fluctuation of service；The best method solved the above problems
It is, using static cooler i.e. Semi-coke cooling device, effectively to cool down semicoke, reclaim semicoke heat, improve semicoke quality, be produced into
This is low, stable, there is good economic benefit.
Using swinging or the scale low temperature pyrogenation technology of other forms, discharged after fine coal or small-particle coal low temperature pyrogenation
Semicoke, its usual temperature is at 400-550 DEG C, and quantum of output is huge, and recyclable sensible heat is a considerable number of.To prevent high temperature half
Jiao is discharged directly to burn in air, while being also to reclaim sensible heat contained by semicoke, it is necessary to configure the waste heat of high-efficiency and economic
Reclaim and cooling device.
However, in the cooling of existing particulate matter and heat recovery technology, available is generally this of use vertical structure
Class device.Hot particulate material is entered by device upper end, and is moved down by deadweight.In the process, it is vertical by being arranged in
Heat exchanger tube in housing, passes to cooling water and absorbs heat and cool down semicoke.Absorbing the water after heat can produce after certain temperature is reached
Raw steam, by the steam-water separation in drum, produces saturated vapor for using it for anything else.Due between solid granule thing and cooling water
Heat exchange it is slower, especially at the less rear portion of heat transfer temperature difference.Little particle semicoke in operation is pyrolyzed to scale, to make
Temperature is reduced, it usually needs very big heat exchange area, the height that this allows for vertical heat exchanging device is higher, and volume is also very huge
Greatly.So so that the setting height(from bottom) of whole process system, especially front end pyrolysis kiln is also increased, work is thus considerably increased
The investment of process system installation foundation and installation expense, also increase the difficulty and workload installed and repaired.According to drop
Low front end is pyrolyzed the setting height(from bottom) of kiln, then hot semicoke is promoted to the feeding mouth of vertical unit using lifting means, then not only
The number of devices of production line is added, and also increases the link for being easy to produce failure, the reliability of system operation is reduced.
Therefore, Chinese patent literature 105910448A discloses a kind of combined type little particle semicoke cooling and waste heat recovery dress
Put, including in the vertical section and horizontal segment of structure setting up and down；The vertical section includes offering charging aperture and out quarrel
First Heat Exchanger is provided with vertical piece housing, vertical piece housing；The First Heat Exchanger is connected with drum constitutes circulation loop；
The horizontal segment includes being provided with into bucket on the horizontal piece housing for being provided with charging aperture and discharge gate, the charging aperture of horizontal piece housing
Device is simultaneously connected with the out quarrel of vertical piece housing；In the horizontal piece housing, come in be provided with below quarrel for will be under
The material that glassware is fallen blows afloat the air register shed；In the horizontal piece housing, the second heat exchanger is additionally provided with above air register,
The outlet of second heat exchanger is connected with drum, and import, which is connected with the water tank present apparatus, can improve semicoke waste heat recovery to a certain extent
Efficiency and the stability of operation.But the heat exchanger of the prior art is arranged on cooler center and not contacted with outer wall, heat exchange effect
Rate improves limited, and to be also provided with heat exchanger easy to wear for horizontal segment below, and blocks discharging, and operation stability is not met by reality
Requirement.
The content of the invention
Therefore, the utility model is arranged on cooler center for the heat exchanger of prior art and not contacted with outer wall, exchanges heat
Efficiency improves limited, and below horizontal segment to be also provided with heat exchanger easy to wear, and block discharging, what operation stability was not good enough is scarce
