Description

Low temperature, non-pressure, oxygen-removing and high efficient heat exchanger

Low temperature does not have the deoxygenation of pressure efficient heat exchanger and is mainly used in the heating bath water.

Now the deoxygenation way during the storage heat exchanger processing hot water mainly contains three kinds, and the one, the HTHP deoxygenation, the power consumption of this kind way is big.Second kind of way is deaeration in condenser, the apparatus expensive of this way.The third is to add a device in heat exchanger, fills the iron filings deoxygenation in this device, and this way exists will regularly replace iron filings, the shortcoming of troublesome poeration.Also there is the low deficiency of the thermal efficiency in existing storage heat exchanger.

The purpose of this utility model is a kind of storage heat exchanger of design, be used to heat bath water, this heat exchanger adopts low temperature not have the structure of pressure deoxygenation and cycling hot exchange, make the oxygen corrosion phenomenon of this heat exchanger significantly reduce, the thermal efficiency improves greatly, and obviously prolong the service life of heat exchanger.

The utility model is made up of tank body and the swinging heat-exchange tube that is located in the tank body.The bottom of tank body or bottom are provided with running water water inlet base and boiler blow-down water base, and the middle and upper part of tank body is provided with hot water inlet pipe's seat, is connected with return pipe on the boiler blow-down water base, is connected with suction pump between return pipe and the boiler.Be connected with the water pipe that links to each other with boiler on hot water inlet pipe's seat.Be connected with outlet pipe on hot water effluent's base, be connected to the drainage pipeline pump on the hot water outlet pipe.Running water water inlet base links to each other with the arrival end of swinging heat-exchange tube, and the port of export of swinging heat-exchange tube is located in the tank body, and the port of export also has decompressor.The swinging heat-exchange tube by the end to end swinging of more piece comb be arranged in the tank body.The pipe that hot water effluent's base stretches in the tank body has a blender.Be injected in the tank body by the hot water inlet pipe through the boiler heated hot water, running water enters in the swinging heat-exchange tube, in tank body, fully absorb the heat of hot water, after reducing pressure, mix, before going out hot water, mix through blender once more and discharge with hot water in the exit.The water temperature of getting back to boiler is more than 50 ℃, and the water temperature in the tank body because the automatic exhaust steam valve of suction pump and drainage pipeline pump and tank deck makes that the pressure in the tank body is zero, has realized that low temperature does not have the pressure deoxygenation at 50 ℃～90 ℃.

The utility model has realized that in storage heat exchanger low temperature does not have the pressure deoxygenation, makes heat exchanger exempt the corrosion of oxygen, makes prolong greatly the service life of heat exchanger, and equipment manufacturing cost reduces greatly, and simple and convenient operation and maintenance is easily gone.Heat exchanger effectiveness improves greatly, and the boiler blow-down water temperature is more than 50 ℃, so but energy savings about 50%, the utility model can provide bath hot water in 24 hours continuously.
