The utility model is characterized in that the inside of the heat exchange tube in which heating medium flows is provided with a plurality of rotary stream twisted bands; the twisted bands are made into a levorotation section and a dextrorotation section; the front edge of the rear twisted band and the end part of the front twisted band form 90 DEG in malposition mode; the front edge of the rear twisted band and the end part of the front twisted band are alternately connected and are arranged in the heat exchange tube. The inside of the shell body in which cooling medium flows is provided with a plurality of deflecting plates and longitudinal baffles along the longitudinal direction; the inside of the shell body is also provided with an autocontrol temperature regulating valve, an autocontrol pressure regulating valve, and an electromagnetic valve. The utility model can operate automatically and can ensure the stability of supply water temperature. The coefficient of heat transmission is raised by 35-250% and the utility model is suitable for the water supply systems of various constructions.
Description
The utility model belongs to the heat-exchange apparatus that general heat-exchange apparatus, particularly heat exchange medium directly do not contact.
At present, in the hot water supply system of industry and civil buildings, shell-tube type (floating head type) heat exchanger has general application.The structure of existing shell-tube type (floating head type) heat exchanger is that heat exchanger tube is set in tank-like shell, is heating agent with steam or high-temperature water, flows through outside the heat exchanger tube in tank body, and heat is transferred to the heated refrigerant (cold water) that flows in the heat exchanger tube, realizes heat exchange.In order to improve the heat exchange amount, often adopt the method that increases heat exchanger tube radical and length, increase heat exchange area and increase the heat exchange amount.Because the restriction of heat exchanger tube loop length and vome of shell size, thereby the increase of heat exchange amount is that finite sum is sub-economic.
The purpose of this utility model is, heating agent changed in heat exchanger tube flow, and refrigerant changed to outside heat exchanger tube flow, and increases the ratio of refrigerant shared volume in heat exchanger; In heat exchanger tube, increase the turbulent flow measure, outside heat exchanger tube, increase the baffling measure; Hot and cold matchmaker's temperature is carried out automatic control regulate, further improve heat exchange efficiency.
Hemi-fast open shell-tube type of the present utility model (floating head type) heat exchanger, form by tank-like shell and heat exchanger tube, it is characterized in that, be provided with many eddy flow distortion bands within it in two strokes that heating agent flows or the heat exchanger tube of four-stroke, distortion band make one section left-handed, one section dextrorotation, and the leading edge of back one distortion band and the afterbody dislocation 90 of last distortion band are spent, alternately couple together and place in the heat exchanger tube, make fluid be cut apart and do the radial motion of break-in periodically, increase the turbulivity of heat exchanger tube inner fluid, improved heat transfer coefficient; In the housing that refrigerant flows, longitudinally be provided with several deflection plates and longitudinal baffle, can prevent the current short-circuit flow; Be provided with automatic control heat control valve in heating agent (steam or high-temperature water) pipeline import, can change according to the fluctuation that is heated cold water leaving water temperature height, and the size that the automatic regulating valve door is opened, regulate the inflow of heating agent, be heated the leaving water temperature of cold water with control, guarantee that water temperature is within the use water temperature range of customer requirements; Be heated on the water inlet pipe of cold water, establishing automatic control pressure regulator valve, the cold water intake pressure is stabilized within the scope of instructions for use; In lower housing portion, establish magnetic valve, regularly discharge dirt in the housing by electric control panel by instructions for use, in the heat exchanger use, make its automatic operation by electric control panel, guarantee the stable of supply water temperature.
The utility model belongs to a kind of semi instant heating heat exchanger of finite quantity water storage, and certain storage water yield is promptly arranged in the housing, and when the fluctuation of user's water consumption transient change was big, it can reduce hot water effluent's variation of temperature amplitude, guaranteed the use hot water temperature of water.Have the following advantages: because the eddy flow distortion band that many directions change is housed in the heat exchanger tube, increased turbulent flow, strengthened heat transfer, heat transfer coefficient improves 35～250%, under the condition that does not increase the heat exchanger tube heat transfer area, and the heat exchange amount that increase that can be bigger is total; Because heating agent is in heat exchanger tube, in the housing of heated refrigerant outside heat exchanger tube, thereby the outer cover of heat exchanger temperature is lower, and the radiation heat loss greatly reduces; Because heat exchanger has the automatic operation of a threshold quantity storage of water volume and a whole set of automatic control equipment, under the bigger situation of water consumption transient change, still can make to be heated the cold water leaving water temperature and to keep stable, become semi instant heating, and be controlled within the scope of customer requirements serviceability temperature; Because heat transfer coefficient is big, the heat exchanger effectiveness height, its high-temperature steam is after being heated the cold water cooling, and the condensate water leaving water temperature is lower, can be lower than 50 ℃, thereby can save steam trap, and can reduce by 15% left and right sides energy consumption; Owing to be provided with the valve of regular automatic pollution discharge water, can discharge dirt in the pipe at any time, can reduce tube wall incrustation; Whole heat exchanger volume is little, and it is few to take up space, and is easy to carrying; The heat exchanger operable automatically reduces hand labour, and leaving water temperature is guaranteed within the scope of instructions for use.Be applicable in the water system of various industry or civil buildings.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the main pseudosection of hemi-fast open shell-tube type (floating head type) heat exchanger.
Fig. 2 is an eddy flow distortion band structural map in the heat exchanger tube.
As seen from the figure, hemi-fast open shell-tube type (floating head type) heat exchanger, form by tank-like shell and heat exchanger tube, it is characterized in that, be provided with many eddy flows distortions within it in two strokes that heating agent flows or the heat exchanger tube 5 of four-stroke and be with 6, the distortion band make one section left-handed, one section dextrorotation, and the leading edge of back one distortion band and the afterbody dislocation 90 of last distortion band are spent, alternately couple together and place in the heat exchanger tube; In the housing 1 that refrigerant flows, longitudinally be provided with several deflection plates 4 and longitudinal baffle 3, can prevent the current short-circuit flow; Be provided with automatic control heat control valve 7 in heating agent (steam or high-temperature water) pipeline import, can change according to the fluctuation that is heated cold water leaving water temperature height, and the size that the automatic regulating valve door is opened, be heated on the water inlet pipe of cold water, if control pressure regulator valve 10 automatically, the cold water intake pressure is stabilized within the scope of instructions for use; In lower housing portion, establish magnetic valve 9, by electric control panel 16 control, regularly discharge dirt in the housing by instructions for use, in the heat exchanger use, make its automatic operation by electric control panel, guarantee the stable of supply water temperature.2 is end socket among the figure, and 8 is thermometer, and 11 for heating agent enters pipe, and 12 is the condensed water outlet pipe, and 13 for refrigerant enters pipe, and 14 is the hot water outlet pipe, and 15 is blow-off pipe.
