Description
Technical field
This utility model is related to material cooling technology field, more particularly, to a kind of refrigerating device for materials.
Background technology
It is in short supply due to fossil energy, and national energy-saving environmental protection policy is combined, the heat that high-temperature material is carried is used as one
Waste heat is planted, very high recovery value has been realized.Meanwhile, high-temperature material is directly cooled down in atmosphere, also results in dirt
Dye, and environment is affected, therefore high-temperature material is required to cooling, and its heat for carrying is reclaimed, and for heating feedwater, or produce
Raw steam.
Currently, the cooling of high-temperature material, has there is the technical solution of comparative maturity, such as barrel slag cooler, multidirectional
Composite cooler, etc., these technologies typically all adopt air-cooled, water-cooled, or the mode of wind and water combined cooling, can be by high temperature
Material is cooled to less than 80 DEG C, and cooling medium (usually water) is heated between 80~90 DEG C.
In terms of coke cooling, there is the hydronic dry coke quenching technique of noble gases, also there is spray cooling, water-spraying control etc.
Mode, these technologies have been used for many years in metallurgical and chemical industry.
In terms of sintering deposit cooling, mostly using following three kinds of types of cooling：One is flat cooling, and two is belt cooling,
Three is annular cooling, and the common operation principle of these types of cooling is：High-temperature material carries out hot friendship in chassis with cooling air-flow
Change, the heat of material is taken away by gas.
In coal upgrading field, for the cooling of upgraded coal, currently explore.By taking water-cooled as an example, usually water is heated
To feed temperature.Using single high-temperature material, come for produce specified steam for generate electricity or other purposes, at present and also
Without ripe technology.
There are two major defects in prior art：
1) barrel slag cooler technique can not continuously produce the steam of medium temperature and medium pressure and above grade；
2) dry coke quenching technology investment high cost, takes up an area big, system complex.
3) sealing of sintering deposit cooling device is easily failed, and air leak rate of air curtain is big, causes pathogenic wind-warm low it is difficult to be utilized.
Such as Chinese utility model patent CN 203451587U proposes a kind of " a kind of vertical cooling kiln ", the patented technology
In the centrally disposed center blast cap of kiln body, for cooling down high-temperature material.Due to differ greatly (0~300mm) of material particular diameter, thin thing
Material is easily cooled down than larger material, if using the one-step cooling method of the patent, in order to ensure to occur without high-temperature material, needed
Very big air quantity is put into, this will cause to export pathogenic wind-warm reduction, be unfavorable for being recycled by waste heat boiler or other retracting devices.
Therefore, existing material cooling device has that bulky, investment is high, energy consumption is big, plant maintenance workload is big, leakage
The shortcoming that air quantity is big and heat recovery efficiency is low.
The content of the invention
Goal of the invention：This utility model purpose is that the energy consumption existed for existing cooling device for high-temp material is big, recuperation of heat
The low problem of efficiency, there is provided it is a kind of can save energy consumption can improve the refrigerating device for materials of cooling effectiveness again.
To achieve these goals, this utility model employs following technical scheme：A kind of refrigerating device for materials, including
Housing, case top is provided with charging aperture, and housing bottom is provided with discharging opening, and housing side is from top to bottom respectively equipped with discharge pipe I, enters

Further, the discharge pipe I, blast pipe I and discharge pipe II arrange several around housing.
Further, the housing central section is up big and down small taper.
Further, the housing central section is provided with up big and down small reducing step, and the blast pipe I is located at reducing platform
The top of rank.
Further, the discharge pipe I, blast pipe I and discharge pipe II are respectively equipped with pressure reduction control device.
Beneficial effect：
(1) refrigerating device for materials of the present utility model adopts two sections cooling structure, two sections of cooling structures to blow respectively
Cooling, top cooling air feeding technique meets energy regenerating requirement, and bottom cooling air feeding technique meets requirement of the production to material temperature, keeps away
Exempt from the appearance of localized hyperthermia's material；
(2) as a result of said structure, cooling wind is sent into by refrigerating device for materials middle part, in the case of the identical bed of material,
Blast pressure can be reduced, air blast power is reduced, or under identical blast pressure, bed depth can be improved, strengthen cooling effect；
(3) as a result of said structure, the sealing of cooling device is improved, compared with central cooler equipment, air leak rate of air curtain subtracts
Few, the efficiency of heat recovery is improved, and reaches the requirement of environmental protection and energy saving；
(4) chiller may be used alone, can also be used in combination, and concrete arrangement need to be true according to technological requirement
It is fixed.
