According to the smoke condenser with the blowing device provided by the utility model, compressed air is driven to be blown to the outer wall of the condensing pipe in an intermittent manner through the casing pipe type nozzles sleeved on the condensing pipe elbows in the penetrating manner and the annular nozzle parallel to the condensing pipeline, so as to form a condensing liquid film and a non-condensing gas film. Therefore, a total heat exchange coefficient is improved by improving a smaller heat exchange coefficient value, and the heat exchange effect is improved. Meanwhile, the acid condensing liquid on the outer wall of the condensing pipeline is entirely blown, so that the corrosion of the pipeline is reduced and the service life of the pipeline is prolonged.
Description
Technical field
The utility model relates to a kind of flue gas condenser with blow device.
Background technology
Flue gas as multicomponent gas outside pipe in the condensation heat transfer process, when multi-component flue gas runs into lower than the condensation tube wall of the dew point of water wherein, the first condensation of steam in flue gas also forms one deck liquid film on tube wall, near the vapor partial pressure power of wall is descended, condensation process forms a relative negative pressure state around can making tube wall simultaneously, constantly have the incoagulability air accumulation on the liquid film surface, make the incoagulability partial pressure on liquid film surface higher than tube wall incoagulability partial pressure at a distance, can form one deck air film on the top layer of liquid film like this.Air film has increased the resistance of steam molecule to the liquid film diffusion into the surface, and steam molecule must be by diffusing through air film, just can reach the liquid film surface and carry out condensation heat.Air film and liquid film have formed the outer main thermal resistance of condensing heat-exchange tube wall pipe.According to the basic mode of strengthening heat exchange, thermal conductivity factor α
1(air film), α
2(liquid film), α
3(tube wall) manages outer thermal conductivity factor K=1/(1/ α
1+ 1/ α
2+ 1/ α
3), therefore the thermal conductivity factor of air film and liquid film only has increase α much smaller than thermal conductivity factor and the gas side exothermic coefficient of metal pipe-wall
1, α
2Could effectively increase total coefficient of heat transfer, increase the heat exchange amount, reduce the exhaust gas heat loss.
Existing flue gas condenser pipeline adopts fin, rib-type pipeline more, just improves total coefficient of heat transfer from the angle that increases the condensation metal pipe-wall coefficient of heat transfer, and heat transfer effect is undesirable, is far from increasing the effective of air film, the liquid film coefficient of heat transfer.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of flue gas condenser with blow device.
in order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: with the flue gas condenser of blow device, comprise the condenser pipe elbow, the condensation pipe fixed housing, the bushing type shower nozzle, tube connector, the condenser pipe elbow is connected with the condensation pipe fixed housing and is protruding, the bushing type shower nozzle is set on the condenser pipe elbow, the periphery of bushing type shower nozzle is connected with the condensation pipe fixed housing, the bushing type shower nozzle is provided with the emission direction annular jet parallel with condenser pipe, spout is towards the inwall of offside condensation pipe fixed housing, the bushing type shower nozzle is connected with tube connector.
As preferably, also comprise air supply pipe and electromagnetic impulse valve; Air supply pipe is connected with tube connector, and electromagnetic impulse valve is contained on air supply pipe.
As preferably, the both sides of condenser pipe elbow respectively wear a bushing type shower nozzle, and the two ends of tube connector are connected with the bushing type shower nozzle that is located at condenser pipe elbow both sides.
The beneficial effects of the utility model are:
By being set on the bushing type shower nozzle on the condenser pipe elbow, its with the annular jet parallel with condensation pipe, order about compressed air and purge condensate film and the incoagulability air film that forms at the condenser pipe outer wall with intermittent mode, improve Composite Walls in the mode that increases less coefficient of heat transfer value, increase heat transfer effect.Also the acid condensate liquid purging with the condensation pipe outer wall is clean simultaneously, thereby reduces the corrosion to pipeline, extends the life-span of pipeline.
