Description
Technical field
The present invention relates to hot-blast furnace equipment field, more particularly to a kind of replaceable tubular exchanger.
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 as defined in FAO (Food and Agriculture Organization of the United Nation) 5% 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, germinateed
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 exchanges pipe two and uses full weld with heat exchanger plate using welding technique up and down
Connection, as long as there is one to exchange pipe leakage in heat-exchange tube, must be disassembled, or even scrap to whole exchanger.But it is hot
The maximum position of exchanger probability of damage is located at the position being connected with combustion chamber, and it determines the life-span of whole exchanger substantially.
The content of the invention
It is an object of the invention to provide a kind of replaceable tubular exchanger, to solve above-mentioned technical problem.
The replaceable tubular exchanger of the present invention, using connection living, Nesting Technique, high temperature side heat-exchanger tube uses combined type knot
Structure, it is replaceable pipe that one section of the superiors, which exchange pipe, is mobilizable, the exchange Guan Weiyi roots of the following all length in upper strata, long to hand over
Pipe lower end is changed to be welded and fixed with lower power board.Two exchange one sleeve pipe of increase in the middle of pipe up and down, and 2 root pipes are connected.Can be more
The upper end for changing pipe is fixed on power board using a high temperature resistant cast iron nesting.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of replaceable tubular exchanger, it is characterised in that：Including framework (1), framework (1) both sides are provided with shrouding,
Framework (1) top and the bottom are respectively equipped with power board (1.1), lower power board (1.2)；Centre is provided with median septum (1.3)；
Heat-exchange tube (2) is vertically arranged with inside the framework (1), four groups of the heat-exchange tube (2) point is stood, and first group is stood
Be high temperature close to combustion chamber, be that high temperature group is stood, high temperature group grade separation changes pipe for two sections, a upper section is replaceable pipe, replaceable pipe with
It is fixing pipe down, fixing pipe bottom uses with lower power board (1.2) and is welded and fixed；Replaceable pipe lower end is by leading directly to sleeve pipe
(2.2) it is connected with fixing pipe, the upper end of replaceable pipe passes through upper power board (1.1), and is connected with cast iron upper sleeve cover (2.1)；
The vertical heat-exchange tube of other groups is separately fixed on upper and lower power board by the way of welding up and down.
Preferably, the cast iron upper sleeve cover (2.1) is movable part, cross section is circle, and up big and down small, lower diameter is than upper
Opened on the small 0.5mm of bore dia opened up on power board (1.1), the upper power board (1.1) of cast iron upper sleeve cover (2.1) lower end insertion
If hole in it is fixed, refractory cement sealing is poured between several cast iron upper sleeve covers (2.1).
The beneficial effects of the invention are as follows：
The present invention provides a kind of replaceable tubular exchanger, and using connection living, Nesting Technique, high temperature side heat-exchanger tube is used
Fabricated structure, it is replaceable pipe that one section of the superiors, which exchange pipe, if breakage occurs for replaceable pipe, can will exchange the replaceable pipe of pipe
Part is individually replaced, it is to avoid exchanger is overall because of the damage of this section exchange pipe to be scrapped.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Specific embodiments and the drawings are closed, the present invention is expanded on further, but following embodiments are only the preferred embodiments of the present invention, not
All.Based on the embodiment in embodiment, those skilled in the art are obtained on the premise of creative work is not made
Other embodiments, belong to protection scope of the present invention.
The specific embodiment of the present invention is described below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of replaceable tubular exchanger, it is characterised in that：Including framework 1, the both sides of framework 1 are provided with envelope
Plate, the top and the bottom of framework 1 are respectively equipped with power board 1.1, lower power board 1.2；Centre is provided with median septum 1.3；
Be vertically arranged with heat-exchange tube 2 inside framework 1, four groups of the heat-exchange tube 2 point is stood, first group stand for high temperature it is close
Combustion chamber, is that high temperature group is stood, high temperature group grade separation changes pipe for two sections, and it is fixing pipe below replaceable pipe, replaceable pipe that a upper section, which is,
Fixing pipe bottom uses with lower power board 1.2 and is welded and fixed；Replaceable pipe lower end is connected by straight-through sleeve pipe 2.2 and fixing pipe
Connect, the upper end of replaceable pipe passes through upper power board 1.1, and is connected with cast iron upper sleeve cover 2.1；
The vertical heat-exchange tube of other groups is separately fixed on upper and lower power board by the way of welding up and down.
Cast iron upper sleeve cover 2.1 is movable part, and cross section is circle, and up big and down small, lower diameter on upper power board 1.1 than being opened
If the small 0.5mm of bore dia, fixed, several castings in the hole opened up on the upper power board 1.1 of the lower end of cast iron upper sleeve cover 2.1 insertion
Refractory cement sealing is poured between iron upper sleeve cover 2.1.
Replaceable pipe position is temperature highest position in whole heat exchanger, and its life-span determines the longevity of whole exchanger
Life, if breakage occurs for replaceable pipe, can remove upper power board above fire clay, and cast iron upper sleeve cover is taken out, and replaceable pipe is obtained
Mobile space, from 1.3 position of median septum, one one is completely drawn out, similarly from the position of median septum 1.3 by new replaceable pipe
Power board 1.1 is upward through, is inserted still further below in straight-through sleeve pipe 2.2, after all replaceable pipes replacings are finished, in upper power board
All cast iron upper sleeve covers 2.1, fixed replaceable pipe are put on 1.1, then pours refractory cement again and completes sealing.
To coordinate exchanger heat exchange area size, vertical heat exchanger group can be 2 groups, or 4 groups of even more many, flues
A3.1, flue B3.2, flue C3.3, lower elbow A4.1, lower elbow B4.2 also should accordingly increase and decrease.
