In each embodiment of the utility model, preferably, said screw thread is through to smoke outlet from the gas approach end of said cylindrical body.
In each embodiment of the utility model, preferably, said screw thread forms through the helical form process that rolls of cylindrical body.
In each embodiment of the utility model, preferably, said screw thread is left hand thread or right-handed thread, and said screw thread is pin thread or negative thread.
In each embodiment of the utility model, preferably, said screw thread is formed on the inwall of said cylindrical body through independent setting.
In each embodiment of the utility model, preferably, the inwall of said cylindrical body is attached with the acid and alkali-resistance protective layer.
In each embodiment of the utility model, preferably, said acid and alkali-resistance protective layer comprises the acid and alkali-resistance diaphragm.
In each embodiment of the utility model, preferably, said chimney further comprises flue gas processing device, and it is installed in the gas approach end of said chimney.
Chimney through the utility model provides, can bring following beneficial effect:
1. apply to flue gas and take out gravitation, accelerate the velocity of discharge of flue gas.Flue gas rises along the thread helix of chimney, takes out gravitation thereby flue gas applied, and flue gas is discharged sooner.
2. reduce the wearing and tearing and the corrosion of chimney.Flue gas has reduced the corrosion of acidic gas in flue gas to the chimney tube wall when quickening discharge, and reduces the wearing and tearing of dust in flue gas to the chimney tube wall.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; Below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art; Obviously, the accompanying drawing in below describing only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other embodiment and accompanying drawing thereof according to these accompanying drawing illustrated embodiments.
Fig. 1 is the sketch map of a kind of embodiment of the utility model.
Fig. 2 be the utility model a kind of embodiment along A-A among Fig. 1 to profile.
The specific embodiment
Below will combine accompanying drawing that the technical scheme of each embodiment of the utility model is carried out clear, complete description, obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are resulting all other embodiment under the prerequisite of not making creative work, all belong to the scope that the utility model is protected.
The utility model provides a kind of chimney, comprising:
Roll the cylindrical body that forms with helical form;
The said cylindrical body in inwall upper edge of said cylindrical body axially on comprise screw thread.
In Fig. 1, cylindrical body 1 by plate in the shape of a spiral shape roll and form, be convenient to form screw thread 2 at the cylindrical body inwall.Preferably, the material of plate is a stainless steel, and its corrosion resistance is superior to carbon steel of the prior art.Preferably, the wall thickness of plate is 3mm.
In Fig. 2, screw thread 2 is positioned on the inwall of cylindrical body 1, and along the axis direction setting of cylindrical body.Screw thread extends upward from the end of said cylindrical body near boiler, makes flue gas rise to the other end of cylindrical body near an end of boiler along thread helix from cylindrical body, and from chimney, discharges.
The outer wall of cylindrical body can have screw thread or not have screw thread.
In each embodiment of the utility model, preferably, said screw thread is through to smoke outlet from the gas approach end of said cylindrical body.
In Fig. 2, when screw thread 2 when said cylindrical body 1 is through to the other end near an end of boiler, in Fig. 2, the bottom of cylindrical body 1 is near an end of boiler.Be covered with screw thread on the inwall of cylindrical body fully, flue gas is discharged sooner.
In each embodiment of the utility model, preferably, said screw thread forms through the helical form process that rolls of cylindrical body.
The helical form process of rolling through cylindrical body can be formed directly in screw thread, and it is easier, convenient to go out screw thread with respect to car again.
In each embodiment of the utility model, preferably, said screw thread is left hand thread or right-handed thread, and said screw thread is pin thread or negative thread.
Preferably, plate is in the process of rolling, because the direction that rolls is different, causes the direction of the screw thread that rolls formation different, is left hand thread or right-handed thread.Preferably, because the not volume part of plate makes the screw thread of formation pin thread or negative thread can occur with to roll up position partly different when rolling.Begin to roll from the end of said cylindrical body, rolling up on the part or the not volume of said plate partly is glanded when rolling up under the part, form pin thread, flue gas is discharged from chimney along screw thread when the part gland of not rolling up of plate near boiler; When the not volume part gland of plate is being rolled up on the part; Form negative thread, preferably, negative thread can not receive stopping of screw thread flue gas when discharging; More be prone to discharge, so when rolling, preferentially select the roll mode of part gland on rolling up partly of not rolling up with plate.
In each embodiment of the utility model, preferably, the inwall of said cylindrical body is attached with the acid and alkali-resistance protective layer.
The inwall of cylindrical body comprises one deck acid and alkali-resistance protective layer; Can anti-acidic gas in flue gas, the corrosion of alkaline gas or other corrosive gas; Simultaneously also can play certain inhibitory action to the wearing and tearing of chimney, thereby the tube wall to chimney plays a protective role further on the basis of screw thread to dust.
In each embodiment of the utility model, preferably, said acid and alkali-resistance protective layer comprises the acid and alkali-resistance diaphragm.
Diaphragm is a kind of of protective layer, and the acid and alkali-resistance diaphragm is the diaphragm of anti-acidic gas in flue gas, alkaline gas or the corrosion of other corrosive gas.Except that over-protective film, also can be the protection structure of other solids etc.
In each embodiment of the utility model, preferably, said chimney further comprises flue gas processing device, and it is installed in the gas approach end of said chimney.
Gas approach end at chimney is installed flue gas processing device, can carry out preliminary treatment to acidic gas in flue gas or other corrosive gas earlier, and preliminary treatment comprises chemical reaction or other processing etc., thereby reduces the corrosivity of flue gas to the chimney tube wall.
Chimney through the utility model provides, can bring following beneficial effect:
1. apply to flue gas and take out gravitation, accelerate the velocity of discharge of flue gas.Flue gas rises along the thread helix of chimney, takes out gravitation thereby flue gas applied, and flue gas is discharged sooner.
2. reduce the wearing and tearing and the corrosion of chimney.Flue gas has reduced the corrosion of acidic gas in flue gas to the chimney tube wall when quickening discharge, and reduces the wearing and tearing of dust in flue gas to the chimney tube wall.
The various embodiment that the utility model provides can make up with any-mode as required each other, and the technical scheme that obtains through this combination is also in the scope of the utility model.Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also comprises these changes and modification interior.
