Abstract
The utility model discloses an integral heat exchanger with a steam-water phase and a water-water phase, which belongs to heat-exchanging equipment, in particular to an upright shell and tube heat exchanger. The integral heat exchanger with the steam-water phase and the water-water phase comprises a steam inlet, a condensation water outlet, a cold water inlet, a hot water outlet, a shell and a tube bundle, and the utility model has a structure that the condensation water outlet is provided with a baffle plate or a bent tube with a downward opening. The heat exchanger achieves the steam-water heat exchange on the upper part inside a tube shell and the water-water heat exchange on the lower part inside the tube shell, increases length and area of the effective heat exchange of the tube bundle, and reduces working dead angles of the heat exchanger, thereby preventing instantaneous discharge of the steam passing from the condensation water outlet through a steam trap at the same time, and reducing water-discharging temperature of the condensation water; and based on experiments, the temperature of the condensation water can be reduced by 5 to 20 DEG C, and the utilization rate of the heat energy can be increased by 2 to 5 percent. The integral heat exchanger has a simple structure, so that all the prior manufacturing enterprises of heat-exchanging equipment can bring the integral heat exchanger into effect.
Description
Technical field
The utility model belongs to heat transmission equipment, particularly vertical shell-and-tube heat exchanger.
Background technology
In the heat supply heating heat exchange station, adopt the vertical shell-and-tube vapor-water heat exchanger widely, its heat exchange efficiency simple in structure is higher, but because the lower limb office tube sheet of the condensed water delivery port of the existing vertical shell-and-tube vapor-water heat exchanger of reasons in structure needs certain height, condensed water is general direct thus flows away along condensation-water drain, the cryogenic condensation water that is deposited on tube shell bottom can not get circulation, be actually the heat exchange length that has reduced tube bank, another part steam also can be discharged the waste that causes heat with condensed water simultaneously.
The utility model content
In order to overcome the deficiency of existing vertical shell-and-tube vapor-water heat exchanger tube shell bottom heat exchange situation difference, the purpose of this utility model provides a kind of carbonated drink, the two-phase integrated heat exchanger of water water, and this carbonated drink, the two-phase integrated heat exchanger of water water can effectively be realized the cryogenic condensation water circulation of tube shell bottom and can prevent that steam from discharging with condensed water.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of carbonated drink, the two-phase integrated heat exchanger of water water, comprise steam inlet, condensation-water drain, cooling water inlet, hot water outlet, housing, tube bank, it is characterized in that: baffle plate or the bend pipe that Open Side Down are housed at condensation-water drain.
Described baffle plate is a curved baffle.
Described curved baffle top edge is welded on and is higher than condensation-water drain upper wall 5--20cm place, and left and right edges is welded on 0-15cm place, condensation-water drain both sides, and lower limb is lower than condensation-water drain lower wall 0-15cm.
The described bend pipe that Open Side Down is pipe or flat tube or square tube, and the bend pipe end opening is lower than condensation-water drain lower wall 0-15cm.
Owing to the lower wall that curved baffle or the bend pipe that Open Side Down and its lower limb are lower than condensation-water drain is housed at condensation-water drain, condensed water is discharged with U type water route through baffle plate or bend pipe, just avoided condensed water and part steam directly to drain from condensation-water drain, baffle plate or the bend pipe that Open Side Down rise to the condensation-water drain discharge from baffle plate after can forcing condensed water to be recycled to the tube bank bottom again, realized shell internal upper part steam-water heat exchanging, bottom water water heat exchange, the effective heat exchange length and the area of tube bank have been increased like this with regard to the temperature that has improved housing bottom, prevent also that simultaneously steam from discharging from condensation-water drain, realize discharged at lower temperature, test the delivery port condensate temperature factually and can reduce by 5-20 ℃, improve heat energy utilization rate 2-5%.
The beneficial effects of the utility model are that this heat exchanger has been realized shell internal upper part steam-water heat exchanging, bottom water water heat exchange, the effective heat exchange length and the area of tube bank have been increased, reduced the working angle of heat exchanger, prevent also that simultaneously steam from discharging when the steam trap from condensation-water drain moment, can reduce the temperature at discharging condensate of condensed water, test factually and can reduce by 5-20 ℃ of condensate temperatures, improve heat energy utilization rate 2-5%.The utility model original heat transmission equipment simple in structure manufacturing enterprise can implement.
