The outer layer of attached layer 31 is provided with the first inner ring water leg layer 32, and the outer layer of the first inner ring water leg layer 32 is provided with second
Ring anti adhering layer 33；One side lower part of the first inner ring absorbing and cooling temperature unit is provided with and the first inner ring water leg layer 32
First inner ring water leg water inlet pipe 51 of connection, its another upper lateral part is symmetrically arranged with to be connected with the first inner ring water leg layer 32
The the first inner ring water leg outlet pipe 52 connect.
During work, high-temperature flue gas is entered in heat absorbing conduit body 1 by underflue, and cooling water is pressed from both sides from the first inner ring water
Set water inlet pipe 51 enters, then into the first inner ring water leg layer 32, and with entering the high temperature in heat absorbing conduit body 1
Flue gas carries out heat exchange, and the flue gas after cooling is discharged into top flue, due to devising the first inner ring water leg layer 32, with regard to shape
Into inside-and-outside ring multi-airway, heat exchange area and the coefficient of heat transfer are greatly increased, heat exchange efficiency and heat exchange amount is improved.
During design, in order to further improve absorbing and cooling temperature effect, it can be provided with the inwall of the heat absorbing conduit body 1
Second outer shroud absorbing and cooling temperature unit, the second outer shroud absorbing and cooling temperature unit includes being arranged on the anti-adhesion of the second outer shroud of innermost layer
Layer 21, the outer layer of the second outer shroud anti adhering layer 21 is provided with the second outer shroud water leg layer 22, the second outer shroud water leg
The outer layer of layer 22 is provided with the second outer shroud heat-insulation layer 23；One side lower part of the heat absorbing conduit body 1 is provided with and described second
Second outer shroud water leg water inlet pipe 41 of the connection of outer shroud water leg layer 23, its another upper lateral part be symmetrically arranged with outside described second
Second outer shroud water leg outlet pipe 42 of the connection of ring water leg layer 23.
During work, high-temperature flue gas is entered in heat absorbing conduit body 1 by underflue, and cooling water is pressed from both sides from the second outer shroud water
Set water inlet pipe 41 enters, then into the second outer shroud water leg layer 22, and with entering the high temperature in heat absorbing conduit body 1
Flue gas carries out heat exchange, and the flue gas after cooling is discharged into top flue, due to devising the second outer shroud water leg layer 22, significantly
The heat exchange area and the coefficient of heat transfer of outer shroud air flue high temperature flue gas are added, heat exchange efficiency and heat exchange amount is improved.
Wherein, the heat absorbing conduit body 1 is made up of the hollow steel part of circular in cross-section, the two ends of the hollow steel part
The round flange being engaged with the hollow steel part is symmetrically arranged with, the outward flange side of the round flange is oblique provided with type is carved
Face, the adjacent round flange forms two-sided carve outside flanged ring and two-sided outside type inclined-plane 3, the flanged ring carves type inclined-plane after coordinating
It is covered with two semicircle anchor ears outside 3, the semicircle anchor ear boring and provided with carving type with two-sided outside the flanged ring
Two-sided carve is fastened by bolts part 5 and connected in the anchor ear that inclined-plane is engaged between type inclined-plane 4, and the semicircle anchor ear.In spiral shell
When bolt is fastened, the interior two-sided type inclined-plane of carving of two semicircle anchor ears is being incited somebody to action two-sided type inclined-plane of carving produces thrust outside on flanged ring
While two adjacent ribs rings are fastened, also the seal of two flange interannulars is compressed, quick connection had not only been realized but also had realized fast
Speed sealing, is applicable high-temperature severe environment.
The tedge absorbing and cooling temperature device of the present invention is coke oven, gas generator, is hydrogenated with the equipment such as stove and petrochemical refining
The outlet segment pipe that high temperature coke oven coal gas, coal gas, oil gas, flue gas etc. are discharged upwards, to reduce the exhaust temperature of gas, fully
Using its heat, the present invention is mounted with water leg layer in this segment pipe, water leg is carried out heat absorption heat exchange with high-temperature gas, will
Water at low temperature is heated to be high-temperature water or steam water interface, can become steam from hot outlet discharge, then by steam generator, supply
Heating equipment is used, and directly can also use its heat for heating equipment.
Due in above-mentioned gas containing a large amount of tar, how, the impurity such as crude benzol, dust, be easily attached on inner-walls of duct, make
Into line clogging, the exhaust resistance of equipment that exchanges heat but also increase not only is influenceed, it is not used normally.So, in the interior table of pipeline
One layer of not only anti-impurity adhesion but also anti adhering layer that will not be heat-insulated are attached on face, also requires that absorbing and cooling temperature device used can both absorb heat
Pipeline internal resistance can not be increased again, can be used again on the premise of equipment normal discharge is not influenceed.This is why can not to use
Common heat exchanger reason, designed tedge absorbing and cooling temperature device must not increase pipeline while increase heat exchange area as far as possible
Resistance and influence gas to discharge.
It can be seen that, the present invention has simple in construction, and it is convenient that installing/dismounting is changed, the advantages of maintenance replacing construction is short, setting
Water leg layer can cool to the high-temperature flue gas in flue, while the hot water after cold water hot-cast socket can also be carried out into profit
With because there is anti adhering layer at heat-transfer surface and the hot gas contact heat-exchanging position on the outside of water leg layer, can preventing miscellaneous in flue gas
Matter is sticked in flue, causes flue blockage.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
