Background technology
At present, the printworks pre-treatment is moved back a large amount of underground water (about 15 ℃), running water (about 8 ℃-20 ℃) or river, river lake water (about 0 ℃-30 ℃) etc. of using such as boiling and bleaching process, washing process as the water source.Heat to 95 ℃ of-98 ℃ of destarch, washing through steam, the high temperature sewage that has dirts such as slurry, dyestuff after a large amount of simultaneously the use is discharged into Sewage Disposal.On the one hand a large amount of cold water are heated to 95 ℃-98 ℃ technological temperature, need a large amount of steam; Pai Fang high temperature sewage is totally unfavorable to the existing biochemical process sewage disposal of generally adopting again on the other hand, needs cooling earlier, and the resources such as consume electric power, water, place equipment again of lowering the temperature produce new expense.
Summary of the invention
The purpose of this utility model is to provide a kind of can replace the heat energy in the hot sewage in the water purification, saves the energy, the heat exchanger that the thermal efficiency is high.
For reaching above purpose, a kind of heat exchanger, mainly by spent hot water's casing, heat-exchanger rig, connecting tube, spent hot water's import, spent hot water's outlet, cold water inlet, the cold water delivery port is formed, it is characterized in that, be respectively equipped with spent hot water's import and spent hot water outlet in the upper and lower, two ends of spent hot water's casing, in spent hot water's casing, be provided with a plurality of heat-exchanger rigs, be equipped with the double-deck water fender that is connected with spent hot water's casing between each heat-exchanger rig, each heat-exchanger rig connects by connecting tube and connects, upper and lower at heat-exchanger rig is respectively equipped with heat exchanging chamber, described heat exchanging chamber connects by the heat exchanger tube that is evenly distributed and connects, cold water inlet is connected with the heat exchanging chamber of a heat-exchanger rig bottom, and the cold water delivery port is connected with the heat exchanging chamber on a heat-exchanger rig top.
End at spent hot water's casing is provided with the elevating lever that is connected with spent hot water's outlet.
Spent hot water's entrance point at spent hot water's casing is provided with spent hot water's water gage.
By above setting, heat-exchanger rig tube chamber formula unibody construction is when having guaranteed that heat exchange area is enough big, and water resistance has also been accomplished very little; Advance cold water under the water purification, on go out hot water, the enterprising hot water of waste water, the Inlet and outlet water mode that goes out down cold water meets thermodynamic principles, fabulous assurance heat exchange effect; The double-deck water fender of unique design has guaranteed that well thermal wastewater all accomplishes enterprising hot water, goes out the optimal heat exchange water flow mode of cold water down at each grade, guarantees that thermal wastewater discharges not short circuit.The present invention can replace the heat energy in the hot sewage in the water purification, and the thermal efficiency is high, through experimental verification, moves back to boil in the continous way of printworks and floats (about 8m in the equipment normal process flow
3/ h), can be preheating to 15 ℃ underground water 70 ℃, be applied to again on the equipment, when saving steam, shortened heat time heating time again, improved the washing effect; Simultaneously 90 ℃ high temperature sewage has been reduced to discharging below 30 ℃, has solved the difficult problem in the sewage disposal again, the present invention also have take up an area of minimum, cost is low, no operating cost, is convenient to series of advantages such as clean and maintenance.
Description of drawings
Now the utility model is described in further detail in conjunction with the accompanying drawings
Fig. 1 is the utility model front view
Fig. 2 is the utility model vertical view
Fig. 3 is the utility model left view
Fig. 4 is the utility model right view
Among the figure 1, connecting tube 2, elevating lever 3, telescoping tube 4, spent hot water's import 5, heat exchanging chamber 6, heat exchanger tube 7, spent hot water export 8, cold water delivery port 9, cold water inlet 10, spent hot water's water gage 11, spent hot water's casing 12, double-deck water fender A, heat-exchanger rig
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is mainly by spent hot water's casing 11, heat-exchanger rig A, connecting tube 1, spent hot water's import 4, the spent hot water exports 7, cold water inlet 9, cold water delivery port 8 is formed, be respectively equipped with spent hot water's import 4 in the upper and lower, two ends of spent hot water's casing 11 and the spent hot water exports 7, in spent hot water's casing 11, be provided with a plurality of heat-exchanger rig A, be equipped with the double-deck water fender 12 that is connected with spent hot water's casing 11 between each heat-exchanger rig A, each heat-exchanger rig A connects by connecting tube 1 and connects, be respectively equipped with identical heat exchanging chamber 5 in the upper and lower of each heat-exchanger rig A, described each heat exchanging chamber 5 connects by the heat exchanger tube 6 that is evenly distributed and connects, cold water inlet 9 is connected with the heat exchanging chamber of a heat-exchanger rig bottom, and cold water delivery port 8 is connected with the heat exchanging chamber on a heat-exchanger rig top.Be provided with the spent hot water at an end of spent hot water's casing 11 and export 7 elevating levers that are connected 2, spent hot water's import 4 ends at spent hot water's casing 11 are provided with spent hot water's water gage 10.
