Description
Technical field:
The utility model relates to the secondary heat exchange systems of a kind of pair of material heating and cooling.
Background technique:
Some materials need for material to be warming up to reaction temperature in initial reaction stage in Chemical Manufacture, and material heat release reacts
When, to cool down to material, heat of reaction is taken away in time.Current method is that steam and object are directly utilized in heat exchanger
Material heat exchange, heats up to material；The steam valve that heat exchanger is closed when cooling, opens the recirculated water valve of heat exchanger directly to material
Cooling.Disadvantage is that: range of temperature is big, and control is difficult, and temperature control precision is low；What recirculated water and steam switched
Initial stage, it may appear that water hammer, vibration is larger, and heat exchanging device causes centainly to damage.
Summary of the invention:
The technical problem to be solved by the utility model is to provide a kind of structure is simple, equipment is few, and pipeline is few, does not pollute ring
The energy-saving secondary heat exchange system in border.
Above-mentioned purpose is achieved in that it includes heat exchanger, heater, cooler, is material in the shell side of heat exchanger,
It is softened water in heat exchanger tube pass, heat exchanger is equipped with the feed pipe and discharge pipe being connected with shell side, the tube side of heat exchanger
Outlet is connected with the tube-side inlet of heater by first pipe, and the tube side outlet of heater and the entrance of circulating pump pass through second
Pipeline is connected, and second pipe is equipped with the first valve, passes through third pipe between the outlet of circulating pump and the tube-side inlet of heat exchanger
Road is connected, and has the second valve on third pipeline；Heater is equipped with the steam that is connected with shell side into and out of pipeline；
The 4th pipeline is also connected in first pipe, the other end of the 4th pipeline is connected with the shell side inlet of cooler, cold
But the shell-side outlet of device is connected with pump entry by the 5th pipeline, has third valve on the 5th pipeline；Cooler is equipped with
The recirculated water being connected with tube side is into and out of pipeline；
It further include expansion slot, the bottom of expansion slot is connected with the 6th pipeline, the other end and the third pipeline phase of the 6th pipeline
Connection has valve on the 6th pipeline, is connected with nitrogen inlet duct road and exhaust pipe at the top of expansion slot, on nitrogen inlet duct road
Equipped with the 4th valve, there is the 5th valve on exhaust pipe.
The utility model has the advantages that: the medium in heat exchanger tube pass is softened water, by nitrogen inlet duct road to expansion
Lead to part nitrogen in slot, material opens the valve on second pipe when initial reaction needs to heat, and closes on the 5th pipeline
Valve heats the softened water in heater using steam, and the softened water of heating is heated to the material in heat exchanger；
When material needs to cool down, the valve on second pipe is closed, the valve on the 5th pipeline is opened, utilizes recirculated water
Cool down to softened water, softened water cools down to the material in heat exchanger.Softening can be by the 6th pipe when coolant-temperature gage increases volume expansion
Road enters in expansion slot, due to having nitrogen in expansion slot, can prevent softening water vapor.
Using softened water as intermediate heat transferring medium, can prevent because directly heating up and dropping to material by steam or recirculated water
Temperature causes the problem that range of temperature is big, control is difficult, temperature control precision is low.Recirculated water and steam will not be because going out when switching
Existing water hammer and heat exchanging device causes to damage.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment:
Referring to Fig.1, it includes heat exchanger 1, heater 2, cooler 3, is material, heat exchanger tube pass in the shell side of heat exchanger
It is inside softened water, heat exchanger is equipped with the feed pipe 4 and discharge pipe 5 being connected with shell side, and the tube side of heat exchanger exports and adds
The tube-side inlet of hot device is connected by first pipe 6, and the tube side outlet of heater and the entrance of circulating pump 9 pass through second pipe 7
It is connected, second pipe is equipped with the first valve 8, passes through third pipeline 10 between the outlet of circulating pump and the tube-side inlet of heat exchanger
It is connected, there is the second valve 11 on third pipeline；Heater is equipped with the steam that is connected with shell side into and out of pipeline；
The 4th pipeline 12 is also connected in first pipe, the other end of the 4th pipeline is connected with the shell side inlet of cooler 3,
The shell-side outlet of cooler is connected with pump entry by the 5th pipeline 13, has third valve 14 on the 5th pipeline；Cooler
The recirculated water that is connected with tube side is equipped with into and out of pipeline；
It further include expansion slot 15, the bottom of expansion slot is connected with the 6th pipeline 16, the other end and third pipe of the 6th pipeline
