Coil pipe includes a dialer pipe and two dialer pipes, the head end connection steam inlet pipe of a dialer pipe, the end company of a dialer pipe The head end of two dialer pipes is connect, the end of two dialer pipes is connected to the head end of straight tube, and the end of straight tube is connected on steam outlet pipe;Housing By inclined transmission mouth formation eddy flow, two are formed when it is by a dialer pipe and two dialer pipes in itself for interior heat transferring medium Secondary eddy flow, uniform mixing of medium when by housing, facilitates the uniform heat exchange in housing.
As a kind of improvement of the present utility model, described steam inlet pipe connects a many dialer pipes by air flow distribution tube, Described steam outlet pipe connects many straight tubes by air flow distribution tube;Pass through uniformly distribution and the collection heat exchange of two air flow distribution tubes Steam, is operated, it is ensured that the uniform feeding and uniform discharge of each group heat exchanging pipe in housing for large batch of indirect steam, is coordinated The heat transferring medium of housing inward eddy, facilitates the uniform heat exchange in housing.
As a kind of improvement of the present utility model, the steam outlet pipe of described hull outside is interior provided with the resistance of vertically arranged twice The steam outlet pipe flowed between screen cloth, twice choked flow screen cloth is provided with tail washings collecting tank;After the completion of heat exchange, one can be produced in pipeline Partial condensation liquid, is collected by tail washings collecting tank, is discharged for the gas of condensation by steam outlet pipe.
As a kind of improvement of the present utility model, the center of described liquid distributing board is provided with circular through hole, steam outlet pipe It is connected to through through hole in air flow distribution tube;Steam outlet pipe is simultaneously installed in the center of liquid distributing board and medium entrance, and gas exists During by steam outlet pipe, being exchanged heat with the medium in liquid distributing board and medium entrance, there is provided the overall heat exchange efficiency of device.
The utility model has the advantage of:The utility model in heat exchanger shell by adding changing for multigroup special construction Pipe line, improves gas residence time in housing, facilitates the abundant heat exchange of gas and medium, multigroup heat exchanging pipe can be used for Exchanged heat while high-volume steam, the overall operating efficiency of device is high;A large amount of steam by exchange heat housing when, heat exchanging pipe The velocity of medium of inside and outside both sides is stable, the occurrence of solving because exchanging heat uneven caused by local velocity inequality.
