Description
Technical field
The present invention relates to a kind of temperature adjustable type natural wind cooler, be mainly used in industrial furnace high-temperature flue gas cooling, have
Cooling extent and the feature of outlet temperature regulation；Can be in field application such as metallurgy, petrochemical industry, building materials, environmental protection.
Background technology
High-temperature flue gas cooling has various ways, and wherein natural wind cooler is one of chiller, and it is to utilize atmospheric environment
In air carry out a kind of flue gas cooling device of natural heat dissipation, traditional natural wind cooler be metallic conduit is fabricated to snakelike
The structure bent the most back and forth, snake pipe can be plurality of rows of, unpowered energy consumption, should in commercial production and environment-friendly engineering
With quite varied.But traditional natural air cooled device has the disadvantages that 1, cooling extent can not regulate, exit gas temperature without
Method controls, bigger by entrance flue gas temperature fluctuation and climatic effect；2, there is no pre-dedusting function and Mars trapping function, pipeline
Easily dust stratification and abrasion；3, owing to being unicast form, take up an area bigger when identical area of dissipation.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of temperature adjustable type natural wind cooler.
The technical solution of the present invention is: a kind of temperature adjustable type natural wind cooler, including:
Forced air cooled tube, described forced air cooled tube both sides are straight tube, and mid portion is n shape pipe；
Inlet box, described inlet box is welded on the top of described forced air cooled tube straight tube；
Air outlet box, described air outlet box is welded on the top of described forced air cooled tube another side straight tube；
Expansion chamber, described expansion chamber is arranged on the bottom of forced air cooled tube；
Ash bucket, described ash bucket is arranged on the bottom of expansion chamber.
Described expansion chamber is two, has dividing plate between two expansion chambers, is provided with short valve on dividing plate；Flue gas enters wind
Forced air cooled tube radiating and cooling can be passed through after cooler, big particulate matter and Mars can be removed in expansion chamber simultaneously；By regulation
The aperture of short valve 7, can cause flue gas short circuit, thus regulate flue gas cool-down amplitude and outlet temperature.
The multiple rows of arranged of described forced air cooled tube, quantity and size can regulate, according to exhaust gas volumn and the requirement of cooling extent
Determining, row is the most, and area of dissipation is the biggest, and cooling extent is the biggest, and outlet temperature is the lowest.
It is to adjust that the n shape pipe of described forced air cooled tube is provided with switching valve, the unlatching number of described switching valve and closedown number, logical
Cross the unlatching number of switching valve and close number regulation area of dissipation；When smoke inlet temperature is too low, close a number of valve,
Increase the exhaust gas volumn of short circuit, flue gas exit temperature can be improved, prevent the supercool condensation of exiting flue gas.
The operation principle of this air cooler is: it is heavy that high-temperature hot flue gas is entered into by the straight tube of cooling tube from inlet box
Fall room, removes the bulky grain in flue gas and Mars at this, enters cooling tube n shape pipe and dispels the heat, further at the 2nd expansion chamber
Sedimentation, finally enters air outlet box from the another side straight tube rising cooling tube and discharges；When inlet temperature is too low, opens, close simultaneously
Closing part is cut and is changed valve, makes flue gas short circuit, can improve exit gas temperature, reduces cooling extent；Ash bucket is deposited ash and is periodically got rid of.
The beneficial effects of the present invention is and can make cooling high-temperature flue gas, the bulky grain in the most removable flue gas and fire
Star, and cooling extent and flue gas exit temperature can be adjusted, unpowered energy consumption；This apparatus structure is simple, floor space
Little, easy to operate, can be widely used for the cooling down of industrial furnace high-temperature flue gas.

Detailed description of the invention
The present invention is described further below in conjunction with the accompanying drawings.
1, according to exhaust gas volumn and cooling extent, forced air cooled tube 2 quantity and size are determined.
2, inlet box 1 is produced respectively, forced air cooled tube 2, expansion chamber 3, air outlet box 4, switch valve 5, dividing plate 6, short valve 7, ash
Bucket 8.
3, on the tube sheet of expansion chamber 3 top, forced air cooled tube 2, the multiple rows of arranged of forced air cooled tube, on forced air cooled tube 2 both sides straight are welded
Pipe top is respectively welded inlet box 1 and air outlet box 4, on the n shape pipe of forced air cooled tube 2 install switching valve 5, two expansion chambers 3 it
Between install dividing plate 6, on dividing plate 6 install short valve 7,3 times installation ash buckets 8 of expansion chamber.
Operation principle of the present invention is: high-temperature hot flue gas enters inlet box 1, and it is heavy to be entered into by the straight tube of cooling tube 2
Fall room 3, removes the bulky grain in flue gas and Mars at this, and the n shape pipe subsequently into cooling tube 2 dispels the heat, the 2nd sedimentation
Room 3 settles further, finally enters air outlet box 4 from the another side straight tube rising cooling tube 2 and discharges；When inlet temperature is too low,
Open short valve 7, simultaneously close off part switching valve 5, make flue gas short circuit, exit gas temperature can be improved, prevent smoke condensation,
Reduce cooling extent；Ash bucket 8 is deposited ash and is periodically got rid of.
Using the device that the present invention proposes, inventor is at Jinan blue star Effect of Catalysis In Petrochemistry cracking unit regenerated flue gas removing dust project
A kind of temperature adjustable type natural wind cooler device that the middle successful implementation present invention proposes, equipment operation condition is good, and technology is joined
Number meets field working conditions requirement.
Flue gas initial parameter:
Smoke property: catalytic cracking unit catalyst regenerated flue gas；
Exhaust gas volumn: 28000 Nm3/h；
Flue-gas temperature: 200 ~ 300 DEG C.
Owing to this engineering sack cleaner to be used carries out dry method dust, the inlet temperature of sack cleaner needs to control
160~230℃.Air cooler before cleaner unit needs possess temp regulating function, if can not regulate, when entering air cooler
When flue-gas temperature is 200 DEG C, according to film-cooled heat fixing in the case of, the flue gas after its cooling possibly lower than dew point temperature,
Easily condense in cleaner unit, do not meet design requirement.
Such as Fig. 1, short valve 7 closed mode, switching valve 5 open mode, natural wind cooler is partial warm down in this case
State, flue gas passes into inlet box 1, then arrives the straight length of forced air cooled tube 2, enters expansion chamber 3, by short valve 7, finally
Air outlet box 4 is arrived from forced air cooled tube 2 port of export straight tube；It is 30 ~ 50 DEG C that flue-gas temperature declines scope, when inlet flue gas is 210 DEG C,
Temperature at most drops to 180 DEG C.
Such as Fig. 2, short valve 7 opening, switching valve 5 closed mode, natural wind cooler is full cooling surface in this case
Long-pending cooling state, the flue gas all forced air cooled tubes 2 of circulation；Flue-gas temperature can be dropped to 220 DEG C by 300 DEG C.
