The summary of the invention the purpose of this utility model is to provide a kind of heat exchange efficiency height, adapted power little, the vertical shell slag cooler of long service life.
Technology solution of the present utility model is: vertical shell slag cooler, comprise feed space, heat-exchanging chamber, discharge chamber and heat exchanger tube, it is characterized in that being distributed with in the heat-exchanging chamber heat-exchanging tube bundle of setting, the upper end of each heat exchanger tube is connected with feed space, the below of heat exchanger tube is provided with the falling control device that the control heat-conduction medium is detained in heat exchanger tube, the below of falling control device is provided with discharge chamber.
Described falling control device is by overhead gage and lower baffle plate and the scraping wings that is positioned on the lower baffle plate, driven by transmission mechanism constitutes, and the material-dropping hole of the material-dropping hole of overhead gage and heat exchanger tube and lower baffle plate shifts to install.
Described falling control device is heat exchanger tube sealed or to constitute with the baffle plate of its maintenance certain distance by moving up and down, and material-dropping hole and heat exchanger tube on the baffle plate shift to install.
The housing of described feed space is have liquid inlet and outlet jacket structured, and its liquid outlet is connected with heat-exchanging chamber.
The upper end of each heat exchanger tube is provided with the reducing tube head.
In feed space, be provided with the pusher impeller that makes the homogeneous media distribution that enters.
The vertical shell slag cooler that the utility model provides is by the reverse flow heat exchange of solid, liquid or solid, vapour phase heat exchange medium.Solid dielectric enters in the slag cooler heat exchanger tube, leans on the gravity of himself to flow downward, and does not therefore need power.Smooth and easy in order to guarantee that solid dielectric flows, be that import is provided with the reducing tube head in the upper end of heat exchanger tube.The time that the speed that solid dielectric flows promptly is trapped in the pipe is controlled by falling control device, to guarantee the abundant heat exchange of two media.
Characteristics of the present utility model are that heat exchanger tube is erect setting, solid dielectric is to flow from top to bottom by its deadweight through heat exchanger tube, this process does not need adapted power and push mechanism, and operating cost is low, long service life, simple and compact for structure, adopt multi-tube structure, its heat exchange area is big, under the prerequisite of equal volume, effective heat exchange area is more than 5 times of other like products, has improved heat exchange efficiency greatly.Complete machine adapted power is little, saves the energy.If slag cooler is used in the less occasion of the flow of solid dielectric, can realize unpowered driving.This slag cooler can be used with CFBB, the high temperature furnace slag about 1000 ℃ can be cooled to below 100 ℃, and heat of slags is recovered in more than 90%, can save a large amount of fire coals.Continuous discharging slag helps stable operation of the boiler.Can also be used for the cooling and the heat exchange of other solid dielectric.
