Description
Technical field
The utility model relates to the apparatus field of exploitation shale gas, particularly relates to a kind of sewage disposal device.
Background technology
Shale gas is the Sweet natural gas contained in shale bed, and the method mainly hydrofracturing method of its exploitation, the mixture by chemical substance, water and silt injects missile silo by high pressure, and the structure of rock near pressure break, then collects Sweet natural gas.Exploiting containing part water in Sweet natural gas out, with 20000nm
3the well head of/d is example, produces sewage every day and is about 20 tons.But again containing the chemical substance (hydrochloric acid, glutaraldehyde, ammonium persulphate, methane amide, borate, Repone K, citric acid etc.) of adding during pressure break in this sewage, make the content of COD in sewage high, be probably 5000 ~ 10000mg/L, far above the requirement of the one-level category-B of standard GB/T 18918-1002, and saltiness is wherein 10 ~ 20 times of seawater.Because the distribution of shale gas well comparatively disperses, be difficult to its collection and uniform disposal, the propulsion source of equipment uses inconvenient, thus the sewage disposal of shale gas by universally acknowledged be more unmanageable sewage.The shale gas sewage disposal device used at present uses chemical agent to process mostly, and not only not thorough to sewage disposal, cost is high, has also carried out secondary pollution to water source, can not reach the standard-required of country.
Summary of the invention
The utility model needs the problem solved to be to provide a kind of sewage disposal device, and this equipment is convenient to be installed, and is easy to be dispersed in different well head and processes, and utilize gas engine waste heat to reduce energy consumption, running cost is low.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of sewage disposal device, comprise sewage inlet, electrochemistry is prized, preheating heat exchanger, afterheat heat exchanger, vaporizer, vapour compressor, solid waste exports, atmospheric outlet, generator, engine, gas inlet, distilled water outlet and pipeline, described electrochemistry sled, preheating heat exchanger, afterheat heat exchanger is connected by pipeline successively with vaporizer, described electrochemistry sled is provided with sewage inlet, described preheating heat exchanger is provided with distilled water outlet, described afterheat heat exchanger is provided with atmospheric outlet, afterheat heat exchanger is connected with engine, described engine is provided with gas inlet, described engine is connected with generator, described vaporizer is provided with solid waste outlet and vapour compressor.
Sewage is successively through a series of chemistry and physical treatment courses such as electrochemistry sled, preheating heat exchanger, afterheat heat exchanger and vaporizers, organism in sewage and salt are discharged in solid form, preheating heat exchanger utilizes the steam in vaporizer tentatively to be heated up by sewage; Due to the dispersion of shale gas exploitation well head, power constant, therefore adopt Sweet natural gas as propulsion source, for gas engine and the power electric generators energy, the tail gas of gas engine is carried out recovery and enters afterheat heat exchanger, the temperature of sewage is raised, and reduces the use power of vapour compressor, save the energy, reduce cost.
Further, described vaporizer is MVR vaporizer.
Further, described vapour compressor is MVR vapour compressor.
Further, described engine is gas engine.
The advantage that the utility model has and positively effect are: this equipment is container-type, easy for installation, due to well head skewness and distribution remoter, power supply inconvenience, therefore the propulsion source that Sweet natural gas runs as it is adopted, be easy to be dispersed in different well head and carry out sewage disposal, the sewage of process can be up to state standards requirement; Utilize the waste heat of gas engine the temperature of sewage to be raised, not only waste heat obtains utilization but also reduces the use power of vapour compressor; This equipment also have simple to operate, safeguard less, running cost is low, it is little to take up an area, invest the advantages such as low.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, the utility model provides a kind of sewage disposal device, comprise sewage inlet 1, electrochemistry sled 2, preheating heat exchanger 3, afterheat heat exchanger 4, vaporizer 5, vapour compressor 6, solid waste outlet 7, atmospheric outlet 8, generator 9, engine 10, gas inlet 11, distilled water outlet 12 and pipeline 13, described electrochemistry sled 2, preheating heat exchanger 3, afterheat heat exchanger 4 is connected by pipeline 13 successively with vaporizer 5, described electrochemistry sled 2 is provided with sewage inlet 1, described preheating heat exchanger 3 is provided with distilled water outlet 12, described afterheat heat exchanger 4 is provided with atmospheric outlet 8, afterheat heat exchanger 4 is connected with engine 9, described engine 9 is provided with gas inlet 11, described engine 9 is connected with generator 9, described vaporizer 5 is provided with solid waste outlet 7 and vapour compressor 6.
Described vaporizer 5 is MVR vaporizer.
Described vapour compressor 6 is MVR vapour compressor.
Described engine 9 is gas engine.
The working process of this example: sewage first enters electrochemistry sled 2 and processes after preliminary sedimentation, by electrode reaction and a series of chemical reaction, electrochemical process and the physical process that cause therefrom, reach the object that contaminant degradation transforms, make the COD drop by half in sewage, and gone out the solid particulate matter in sewage by strainer filtering.Sewage after preliminary treatment enters preheating heat exchanger 3, and left and right is spent in heat exchange to 80, and vapor condensation out in vaporizer 5 is become distilled water discharging up to standard.Enter through the sewage of preheating heat exchanger 3 the high-temperature tail gas heat exchange that afterheat heat exchanger 4 and gas engine 9 produce and temperature is increased to 100 degree further, be convenient to it and evaporate in vaporizer 5.Sewage enters vaporizer 5 and evaporates, and all the other organism in sewage and salt is discharged in solid form, enters the sewage of vaporizer 5 and the steam heat-exchanging through vapour compressor 6 supercharging with high calorie, is vaporized Crystallization Separation and goes out pollutent and water vapour.Circulation like this realizes the process to sewage, and high efficiency of energy is utilized.The electrical energy fed electrochemistry sled 2 that generator 9 produces and vapour compressor 6 use.Water quality after process reaches the requirement of country completely, and solid pollutant regularly transfers to the solid pollutant processing enter process of country.Remoter due to well head skewness, power supply inconvenience, so adopt gas electricity generator 9 to generate electricity, this waste disposal plant process 1 ton of sewage needs about 10nm
3sweet natural gas, and produce 1000nm
3sweet natural gas produce 1 ton of sewage, therefore the amount of the loss Sweet natural gas of this waste disposal plant is about 1% of the turnout of Sweet natural gas, in this equipment, the efficiency of conversion of gas electricity generator 9 is generally 33%, that is the energy of more than 60% is also had to waste with tail hot mode, this waste heat is reclaimed by this device, being used in MVR evaporates in flow process, and not only waste heat obtains the power utilizing but also reduce MVR vapour compressor 6.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
