Specific embodiment
The present invention is described in further detail below by specific embodiment and in conjunction with attached drawing.
It as shown in Figs 1-4, is a kind of disturbing flow device for flue gas condensing described in the embodiment of the present invention, feature exists
In, be made of multilayer disturbed flow pipe group 3, disturbed flow pipe group 3 be set to desulfuration absorbing tower interior inlet flue above and and desulfuration absorbing tower
Inner wall connection, disturbed flow pipe group 3 include:
U-tube 7, the setting of two sides straight tube Length discrepancy, multiple U-tubes 7 are arranged in parallel within inside desulfuration absorbing tower at equal intervals
Periphery on, between two U-tubes 7 of arbitrary neighborhood pass through elbow be connected to；
Cooling water inlet 1 is connected to the U-tube 7 of 3 side of lowest level disturbed flow pipe group；
First interface 4, one end are connected to the U-tube 7 of 3 other side of lowest level disturbed flow pipe group, 4 other end of first interface with
Water inlet end connection in upper one layer of disturbed flow pipe group 3；
Cooling water outlet 5 is connected to the U-tube 7 of 3 side of top layer disturbed flow pipe group；
Second interface 6, one end are connected to the U-tube 7 of 3 other side of top layer disturbed flow pipe group, 6 other end of second interface with
The water outlet connection of next layer of disturbed flow pipe group 3.
Multilayer disturbed flow pipe group 3 constitutes smoke condensation device, and each layer of disturbed flow pipe group 3 is made of multiple U-tubes 7, and
The two sides straight tube of adjacent U-tube 7 is connected by elbow, and all U-tubes 7 is made to form connection.Adjacent two layers disturbed flow pipe group 3
It is formed and is connected to by interface, so that entire disturbed flow pipe group 3 also forms the entirety of a connection.Cooling water passes through cooling water inlet 1
It is flowed into lowest level disturbed flow pipe group 3 and in the U-tube of this layer 7 in straight upper one layer of disturbed flow pipe group 3, it is layer by layer upwards, final cold
But water flows into the U-tube 7 in the disturbed flow pipe group 3 of top layer.Flue gas in desulfuration absorbing tower passes upward through each layer disturbed flow pipe group 3
Rise upwards, hot flue gas encounters the U-tube 7 for having cooling water and starts to condense.
Further, the orientation of the U-tube 7 in adjacent disturbed flow pipe group 3 is mutually perpendicular to.In order to in desulfuration absorbing tower
Flue gas play the role of better flow-disturbing, therefore set phase for the orientation of the U-tube 7 in adjacent two layers disturbed flow pipe group 3
It is mutually vertical, so that certain inhibition can be played to the flue gas of rising, flue gas can be made to come into full contact with U-tube 7, it can
It is more effectively carried out condensation.
Further, 50~200mm is divided between adjacent U-tube 7.Interval in the present embodiment between adjacent U-tube 7 is set
It is set to 50~200mm, then needs to be determined according to the flow velocity of flue gas and the flow synthesis of flue gas in actual condition, to cigarette
Gas progress is condensed into foundation sufficiently to determine the interval between two neighboring U-tube 7.
Further, U-tube 7 is the seamless steel pipe of DN50~DN100.It can guarantee that cooling water being capable of smooth outflow first
The leakage of cooling water will not occur for guarantee simultaneously.The tubing of other more resistance to flue gas corrosions can also be selected to make in practical applications
For U-tube 7.
Further, disturbed flow pipe group 3 is equipped with two layers.
Further, elbow diameter is equal with 7 diameter of U-tube.Since elbow need to be attached adjacent U-tube 7, because
This should set the diameter of elbow diameter and U-tube 7 to always, otherwise not can guarantee the leakproofness of connection, it is possible to cause cold
But the leakage of water, has an impact sulfur removal technology.
Further, first interface 4 is connected to second interface 6.
Disturbed flow pipe group 3 in the present embodiment is set as two layers, by first interface 4 and the connection of second interface 6 by upper layer and
The disturbed flow pipe group 3 of lower layer is connected as an entirety, to guarantee that cooling water can flow to all disturbed flow pipe groups 3.And in reality
The number of plies according to the flue gas flow setting disturbed flow pipe group 3 in desulfuration absorbing tower, the more big then disturbed flow pipe group 3 of flue gas flow are needed in
The number of plies it is more, the number of plies on the contrary then that disturbed flow pipe group 3 can be reduced.And adjacent two layers disturbed flow pipe group 3 is then by being set to outermost U
Interface on type pipe 7 is attached, and multilayer disturbed flow pipe group 3 is made to form an entirety.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
