Description
Technical field
The utility model relates to water recovery apparatus field, is specifically related to a kind of energy-saving and emission-reduction return water system.
Background technology
At present, board production needs use steam, and the steam after board production can form condensed water, condensed water is generally directly drained by the hydrophobic valve on pipeline, makes so constantly to add water in boiler, heats water, make water form steam and be supplied to board production, adopt such production system both to add the consumption of water, consume again the resources such as a large amount of coals or natural gas, also do not meet the energy-saving and emission-reduction theory of current industrial implementation simultaneously.
If application number is 201220536659.5, name is called described in " a kind of emission-reduction boiler return water system ", this system comprises boiler, water inlet pipe, production equipment, outlet pipe, described water inlet pipe one end is connected with boiler, the other end is connected with production equipment, described outlet pipe one end is connected with production equipment, the other end is connected with hydrophobic valve, the other end of described hydrophobic valve is connected with recovery tank by the first pipeline, described recovery tank is connected with boiler by water return pipeline, described water return pipeline is provided with back water pump, the other end of described hydrophobic valve has also shunted blast pipe, described blast pipe is provided with exhaust steam valve, the exhaust end of described blast pipe is connected with condensing hot air furnace tank, described condensing hot air furnace tank is connected by second pipe with recovery tank, described second pipe is provided with suction pump.Former no condensation water collection can re-use by this utility model, thus reaches saving water resource, the effect of saving heat energy.
In paper board producing flow process, the steam pressure that different process step needs is different, and a steam pressure independently in return water system is identical.Can only bleed off for the low-pressure steam after drain valve, the low-pressure steam of backwater cannot utilize, in vain waste water resource and heat energy.In existing technological process, need the return water system that respective amount is set according to the quantity of work step, different high steam chambers is set to carry the steam pressure of needs, to meet the demand of different pressures.Cause great energy waste, be unfavorable for energy-saving and emission-reduction.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of energy-saving and emission-reduction return water system, with the object reaching energy-saving and emission-reduction, reduce energy consumption, reduce production cost.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of energy-saving and emission-reduction return water system, comprise main water return tube road and secondary water return pipeline, described main water return tube road comprises the primary steam generating means, steam rates valve, steam jet pump and the indirect steam chamber that are connected in turn by pipeline; Described secondary water return pipeline is provided with low-pressure steam recycling bin; Low-pressure steam recycling bin communicates with the higher pressure steam inlet of steam jet pump.
Preferably, the mist efferent duct outer wall of described steam jet pump is provided with heat-insulation layer.
Compared with prior art, the utility model has the following advantages:
The steam jet pump that main water return tube road is arranged can make full use of the low-pressure steam on secondary water return pipeline, has saved resource, has fallen at the end production cost.And this body structure of the utility model is simple, cost is very low, and energy-conservationly can reach more than 10%, the economic effect highly significant therefore obtained.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and detailed description of the invention, the utility model is described in further detail.
Embodiment 1.
As shown in Figure 1, a kind of energy-saving and emission-reduction return water system, comprises main water return tube road and secondary water return pipeline, and described main water return tube road comprises the primary steam generating means 1, steam rates valve 2, steam jet pump 3 and the indirect steam chamber 4 that are connected in turn by pipeline; Described secondary water return pipeline is provided with low-pressure steam recycling bin 5; Low-pressure steam recycling bin 5 communicates with the higher pressure steam inlet 31 of steam jet pump 3.
The mist efferent duct outer wall of described steam jet pump is provided with heat-insulation layer 6, and heat-insulation layer material is foam.
Primary steam generating means is steam generation boiler.
As shown in Figure 2, steam jet pump 3 comprises higher pressure steam inlet 31, nozzle 32, suction chamber 33, mixing chamber 34 and diffusion room 35 in turn, and suction chamber 33 sidewall is also provided with low-pressure steam inlet 36, nozzle 32 one end connects with higher pressure steam inlet 31, and the other end is arranged in suction chamber 33.
Operation principle: the high steam in primary steam generating means enters steam jet pump through pipeline from higher pressure steam inlet, high steam is after nozzle, and ejection at a high speed, produces low pressure, sucked by low-pressure steam in low-pressure steam recycling bin and mix at mixing chamber, kinetic energy is pressure energy.In the process, high steam and low-pressure steam are mixed to form the middle pressure steam (the high steam pressure inputted by steam rates valve regulation, thus the mixed vapour pressure needed for realizing) that production needs, and send into indirect steam chamber.No low-pressure steam before this system can make full use of, reaches the object of energy-saving and emission-reduction.
Compared with prior art, the utility model has the following advantages:
The steam jet pump that main water return tube road is arranged can make full use of the low-pressure steam on secondary water return pipeline, has saved resource, has fallen at the end production cost.And this body structure of the utility model is simple, cost is very low, and energy-conservationly can reach more than 10%, the economic effect highly significant therefore obtained.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
