Description
Technical field
It stores and exchanges heat the present invention relates to ash-laden gas dedusting, in particular to it is a kind of to be removed based on the three-dimensional ash-laden gas for expanding surface
Dirt stores heat-exchanger rig and system.
Background technique
Currently, there are larger gap in the energy consumption of China's unit product and developed country, using energy source level still lags behind the world
Advanced level.An important reason of this problem is caused to be that the middle low temperature of the highly energy-consuming trades such as metallurgy, chemical industry, building materials is useless
The direct emission of gas, direct emission of high dusty gas of low temperature does not only result in serious environmental pollution in these, also will cause big
Measure the waste of residual heat resources.According to statistics, fume afterheat accounts for the 35% of China's complementary energy, is equivalent to 3.4 hundred million tons of standard coals, however China
Industrial smoke waste heat recovery efficiency only has 30%, more developed country average level low 15%~20%.As it can be seen that improving waste heat recycling
Rate is the only way which must be passed of industrial sector transition and upgrade.
The grit purification of the high ash-laden gas of low temperature is recycled typically separate formula with waste heat and is carried out in current industrial, this form
Bigger equipment volume and occupied area are needed, and increases flow distance i.e. on-way resistance, results in the increase of blower power consumption.
Also, the problem of separate type purification and waste heat recycling are revealed there is also the serious and junction flue gas that radiates, This further reduces
Waste heat recovery rate.Therefore, dedusting and the exploitation of heat-exchange integrated waste-heat recovery device for energy-saving and emission-reduction and improve energy utilization
Efficiency is significant.
Heat pipe has the characteristics that high efficient heat exchanging and adaptability for working condition are strong, is widely used in integrated waste-heat recovery device
In.The plan service life of usual heat pipe waste heat recovery apparatus is 5-8, however, high energy consumption industrial production discharged in it is low
The fly ash granule that generally existing non-ignitable or uncombusted substance and molten metal salt are formed after condensing in the high ash-laden gas of temperature, these
With sweep of gases heat pipe wall surface, particle friction hits tube wall and is easy to wear heating surface metal fly ash granule, and wear
Accumulation finally needs maintenance shut-downs so that heat pipe booster causes heat exchange equipment to fail.In addition, need of the industries such as metallurgy due to production
It wants, the ash-laden gas of discharge haves the characteristics that temperature fluctuation is big, and smoke temperature fluctuation causes heat pipe continually start and stop, this is unfavorable for heat
The long-time service of pipe.The above problem leads to heat exchange of heat pipe, and the service life only has 2-3 in practical applications, once and heat pipe largely damages
Bad to replace in time, this significantly increases equipment and operating cost.
In addition, on the basis of traditional light pipe gravity assisted heat pipe, people designed and developed all kinds of enhanced heat exchange technologies with into
One step improves heat exchange efficiency, such as in inside heat pipe sintered particles, metal mesh and processing microflute etc., spiral ribs are processed outside heat pipe
Piece, H-type fin and sawtooth fin etc..In above-mentioned pipe the production and processing of structure it is more complicated the cost is relatively high, and pipe external fin
The welding or expanded joint that the processing of piece uses generate biggish thermal contact resistance, are unfavorable for heat transfer, in addition there are higher cost and
The problem of production cycle length.As it can be seen that the selection of the gravity assisted heat pipe of economical and efficient and exploitation are most important for efficient waste heat recycling.
In conclusion designing a kind of high for ash-laden gas purification and the integrated system of waste heat recycling and device, selection
The heat pipe of exchange capability of heat is imitated, while solving the problems, such as the abrasion and heat fatigue of heat pipe, high energy consumption Efficiency of Industrial Energy Utilization will be mentioned
Height has decisive role, even more helps to improve China's energy utilization rate, pushes social sustainable development.
Summary of the invention
It is changed technical problem to be solved by the invention is to provide a kind of based on the three-dimensional ash-laden gas dedusting storage for expanding surface
Thermal and system.
In order to solve the above-mentioned technical problem, according to the technique and scheme of the present invention, a kind of ash-laden gas stage purification waste heat returns
Receipts system, including shell, the shell are the rectangular parallelepiped structure of interior sky, and housing central section is provided with partition, which divides shell
It is divided into two chambers up and down, it is characterised in that: underlying chamber is exhaust gases passes, and the chamber being located above is cooling working medium
