Abstract
The utility model provides a pipe casing type gas and water heat exchanger for supplying heat, which takes steam as a heat source to produce hot water, particularly a horizontal steam all-contact type heat-net heating device. The utility model comprises a shell body 1 and a pipe bundle 2 and is characterized in that each heat-transfer pipe which form the pipe bundle 2 adopts a nickel base seep composite structure. The middle bottom of the shell body 1 is equipped with a drain pot 3, and the shell body 1 is communicated with the drain pot 3 through a short pipe. The utility model overcomes the defects of the prior art, and the pipe wall of a heat-transfer pipe of the utility model is not easily form a water film. The bottom of the shell body of a heat exchanger does not accumulate condensation water, the heat exchange is sufficient, and the thermal efficiency is high.
Description
It is that thermal source is produced the shell-and-tube steam water heat exchanger that hot water is used for heat supply, particularly a kind of horizontally-arranged steam full-contact heat exchangers for district heating with steam that the utility model relates to a kind of.
Known horizontally-arranged shell-and-tube heat exchangers for district heating is heated water and flows in heat-transfer pipe, and steam is heating outside pipe.Because tube surface character is limit, the condensate water that forms after the steam heat release easily forms moisture film on tube wall.Like this, make steam be difficult to directly contact, but conduct heat by moisture film with heat-transfer pipe.In addition, the condensate water that forms after the steam heat release is constantly dripped and is accumulated in housing bottom, easily soaks the part heat-transfer pipe.Owing to above-mentioned two reasons, caused known low, the poor thermal efficiency of horizontally-arranged shell-and-tube heat exchangers for district heating exchange capability of heat.
Order of the present utility model is to avoid above-mentioned weak point of the prior art, easily forms the horizontally-arranged steam full-contact heat exchangers for district heating that the no condensate water in the globule, heat exchanger shell bottom is accumulated and propose a kind of tube wall that conducts heat.
The purpose of this utility model can reach by following measure: the horizontally-arranged steam full-contact of the utility model heat exchangers for district heating, comprise housing, tube bank and expansion joint, and each heat-transfer pipe that wherein constitutes tube bank adopts the nickel-base seeping layer composite construction.Central bottom at housing is provided with a drain trap.Housing and this drain trap link by a short tube.
The purpose of this utility model can also reach by following measure:
The volume of the utility model drain trap is 1/5 of vome of shell at least.
The drawing of accompanying drawing is described as follows:
Accompanying drawing is the front view with broken section of the horizontally-arranged steam full-contact of the utility model heat exchangers for district heating.
The utility model is further described below in conjunction with accompanying drawing.
The horizontally-arranged steam full-contact of the utility model heat exchangers for district heating comprises housing 1, heat-transfer pipe 2, and main feature is each heat-transfer pipe that constitutes tube bank 2, adopts the nickel-base seeping layer composite construction.Because the existence of nickel-base seeping layer composite construction makes tube surface have special physicochemical property: the condensate water that produces after the steam heat release is difficult for forming moisture film on tube wall, but forms many globules and constantly come off.Like this, steam is always directly contacted with tube wall.In the heater base design drain trap 3 that connects by short tube is arranged.The volume of jar 3 should be 1/5 of housing 1 volume at least.Like this, have enough abilities of catchmenting, the condensate water of drippage can all be flowed in the drain trap 3.
Compared with the prior art the utility model has the following advantages:
Each heat-transfer pipe of heating surface bank of the present utility model adopts the nickel-base seeping layer composite construction, makes on the tube wall to be difficult for Form moisture film. Heater housing bottom is provided with the drain trap with the ability of enough catchmenting, and makes the heater housing The no condensate water in bottom is accumulated. Therefore, the utility model Horizontal steam all-contact type heat-net heating device is owing to pass No moisture film forms on the heat pipe wall, and can not soaked by condensate water at the heat-transfer pipe of housing bottom, make steam with The contact of each heat-transfer pipe more is tending towards fully, and exchange capability of heat improves greatly, has realized high efficiency vapour-water heat exchange, Its overall heat-transfer coefficient can be enhanced about more than once than prior art.
