Description
Technical field
The present invention relates to a kind of heat-exchange device, in particular to a kind of high-temperature solid bulk cargo heat-exchanger rig.It can be used for high temperature
The recycling of solid granule waste heat, the cooling of industrial high temperature bulk cargo, raw material of industry heating and the cooling of other bulk cargos or heating process.
Background technique
A large amount of to be cooled or Heated Products or waste residue can be generated during modern industrial production, and most of with solid particle
The form of object exists.Such as China's metallurgy, building materials industry generate 4,500,000,000 tons or more high temperature bulk materials every year, and excess heat is more than 100,000,000 tons
Mark coal.Widely used for solid granule indirect heat exchange at present is pipe row's formula heat exchanger.Formula heat exchanger is common is by pipe row
The heat exchanger that round tube fork row or in-line arrangement rearrange.Round tube has bearing capacity good, and manufacturing process is mature simple, manages interior strengthen and changes
The advantages that thermal technology is mature, but solid granule can form stagnation region at the top of round tube around pipe flow and be formed in round tube bottom
Void area, bulk movement speed is lower in stagnation region or stop motion, in void area bulk cargo and heat exchange tube wall intermittent contact or
It does not contact, the size in this twoth area has seriously affected the fluid interchange of particle.And solid granule flows the stagnation to be formed around elliptical tube
Area and void area are significantly less than round tube, and bulk cargo flow resistance is small, are not likely to produce bridge formation and obstruction, and exchange capability of heat is strong, it is easier to real
Existing compact Layout, but elliptical tube bearing capacity is weak and round tube, manage in enhanced heat exchange technology it is still immature, manufacturing process is complicated.
Therefore, formula solid granule heat exchanger is arranged for pipe, is badly in need of a kind of combination round tube and elliptical tube fluid interchange advantage
Heat exchanger tube is insufficient to solve pipe row's formula solid granule heat exchanger technology.
Summary of the invention
It is provided by the invention to aim to overcome that prior art deficiency, it is solid to provide a kind of multitube composite class ellipse heat exchanger tube
Body bulk cargo heat exchanger, manufacturing process is simple, compact-sized, and bearing capacity is good, and bulk cargo flow resistance is small, be not likely to produce bridge formation and
Obstruction, exchange capability of heat are strong.
The technical scheme of the present invention is realized as follows:
A kind of multitube composite class ellipse heat exchanger tube solid granule heat exchanger specific structure of the invention, including from top to bottom
Feed inlet, set of heat exchange tubes and the discharge gate of setting.Set of heat exchange tubes arranges from top to bottom, logical for fluid media (medium) inside set of heat exchange tubes
