Background technology
China is grain-production big country and consumption big country, according to statistics, in threshing, drying, storage, fortune after China's grain harvest
Loss during defeated, processing, consumption etc. is up to 18% or so, considerably beyond the 5% of FAO's regulation mark
It is accurate.In these losses, every year because of climate reasons, cereal has little time to dry or not up to safe moisture causes to go mouldy, germinates
The grain of loss is up to 5%, if being calculated by 500,000,000 ton-grain food is produced per year, equivalent to 25,000,000 ton-grain food, if eating 500g for each person every day
Grain, is available for 6.8 ten thousand people edible 1 year.Therefore, the mechanization of grain dry is more even more important than the mechanization of farm work, and it is
Cereal high yield, the important leverage condition of good harvest.Hot-blast stove is the key equipment in foodstuff adustion system.
At present, conventional tubular exchanger uses upper and lower solder technology, exchanges pipe two and uses full weld with heat exchanger plate
In connection, but hot-blast stove operation, temperature difference is very high, special first group of exchanger temperature amplitude scope be normal temperature to 700 DEG C, it is high
The temperature difference will necessarily arrive the big pulling force that expands with heat and contract with cold, and such heat exchanger plate can deform quickly under hot pulling force effect, metallic plate
The refractory material drawing crack that deformation covers surface, ultimately results in fire.
The content of the invention

Between be provided with two groups of heat-exchange tubes, first group of heat-exchange tube top is nested with heat-resistance stainless steel sleeve pipe, the heat-resistance stainless steel sleeve pipe
With upper power board full weld, first group of heat-exchange tube bottom and lower power board full weld, second group of heat-exchange tube upper and lower side with it is described
Upper and lower power board full weld；Two groups of heat-exchange tubes lower section is provided with lower elbow, be provided with the middle of two groups of heat-exchange tubes three layers every
It is respectively top cooled partition, upper spacer, lower clapboard from plate, top cooled partition is arranged at heat-resistance stainless steel pipe sleeve lower end,
Upper and lower division board is respectively at the 1/3 of heat-exchange tube trisection, at 2/3.
Preferably, first group of heat-exchange tube is 0.5-1mm with the gap of heat-resistance stainless steel inside pipe wall；Heat-exchange tube
Can be up and down in Heat-Resisting Stainless Steel Tube.
Preferably, the Heat-Resisting Stainless Steel Tube lower end is provided with one layer of radiating division board, the radiating division board extends to the
Two groups of heat-exchange tubes.
Preferably, the lower end of the leading bellows is located at the position of lower division board；The upper end of the rear wind-guiding case is located at
The position of upper division board.
Cold wind can be directly through the gap between upper power board and radiating division board, to temperature highest heat-resistance stainless steel
Pipe carries out quick heat radiating.
Two groups of heat-exchange tube lower sections set an elbow, and flue gas enters from first elbow, and 180 degree is turned to by elbow,
From the discharge of second heat-exchange tube.
A wind-guiding case, supporting upper and lower dividing plate, under heating air is certainly rear are respectively provided with before and after heat resistanceheat resistant pulling force tubular exchanger
Portion enters, and " S " type path is walked in exchanger, goes out from exchanger front upper place.
The beneficial effects of the invention are as follows：
The present invention provides a kind of heat resistanceheat resistant pulling force tubular exchanger, and simple structure, first group of heat-exchange tube uses Nesting Technique,
Can effective decomposing material hot-drawn power, improve the service life of exchanger.
