The speed that the equipment of above-mentioned several patent is separated with aqueous vapor in method is lower, is separated and recycles synchronously to complete, and this is divided gas flow and liquid only, and underuse the gas of release, the level of resources utilization is lower.
Summary of the invention
Goal of the invention:
Overcome water, gas in traditional geothermal water gathering-device can not effectively be separated, can not use by safe ready after being separated, the shortcomings such as isolated natural gas accumulating difficulty, a kind of process unit that fully can be separated natural gas in dissolved air water is provided, and handle is from the isolated natural gas combustion (of oil) insitu of Water Soluble Gas separator, improve the temperature of dissolved air water in device, realize the utilization completely of natural gas and hot water in Water Soluble Gas.
Technical scheme:
Dissolved air water Separation process arrangements disclosed by the invention, dissolved air water (or claiming Water Soluble Gas) from geothermal well first can be inputted this device, realize being separated of water and natural gas, and handle is from the isolated natural gas combustion (of oil) insitu of Water Soluble Gas separator, for the dissolved air water in heating and separating device, improve the temperature of dissolved air water in device, realize natural gas in Water Soluble Gas and be almost separated completely with hot water.This device has integrated knockout drum, neat gas burner, heat exchanger components or has water-level gauge (or thermometer) and many valves.
Integration knockout drum leaves dissolved air water access port and delivery port, and gas outlet (discharging to facilitate the natural gas separated in dissolved air water), the dissolved air water of internal reservoir through being separated of knockout drum, knockout drum inside also has heat exchanger components, gas outlet natural gas out (relies on the pressure in integrated knockout drum to be carried by natural gas line, also can supporting natural gas boosting blower fan, the discharge being beneficial to natural gas be separated, pressure in the integrated knockout drum of further reduction) enter neat gas burner burning, its heat produced is used for heating this heat exchanger components, and then add the water of hot knock-out pot inside, finally flowed out from delivery port by the hot water after heating, realize the separation of natural gas and make full use of.Hot water by hot water effluent's transport pump to heating equipment or user.
The dissolved air water of the lower storage of knockout drum is owing to being heated, and temperature improves, and is more conducive to natural gas and evaporates further from water and separate, natural gas content is wherein lowered further.In addition, natural gas line can be installed purifying device for natural gas (such as: dewater steam device), also internally piloted valve and natural gas flowmeter can be installed.
Integral separation device inside can be connected with water-level gauge and measure water level, is externally connected to control device and controls, ensure that separator there will not be dry combustion method phenomenon.
Preferably adopt pressure release separate mode in knockout drum, the pressure of the dissolved air water of namely coming from pipeline is higher than the pressure in knockout drum;
Accelerate for making the gas in dissolved air water to be separated with make to be separated more thorough, can take to install measures such as filling filler in knockout drum, filler can select the fillers such as Boolean ring, open column shape object or turbulence plate, filler has larger porosity and larger specific area, such as: porosity is greater than 80%.Filler requires to possess corrosion resistance, possesses certain structural strength and on-deformable feature in hot water.
Dissolved air water can absorb the heat in water in the process of release natural gas due to gasification, the temperature of dissolved air water will slightly reduce; Utilize combustion of natural gas to heat dissolved air water again, ensure to be separated rear dissolved air water temperature higher than inflow temperature, natural gas will be conducive to and discharge from dissolved air water and be separated.Time such as: when gas-water ratio 1:1(volume ratio), consider the latent heat heat absorption in thermal losses factor and natural gas separation process, water temperature can be made to raise about 2 ~ 6 DEG C.
The shell of dissolved air water knockout drum can be provided with heat-insulation system, and each pipeline also can have insulation, prevents the loss of heat.
Emptying interface can be installed in the bottom of knockout drum, to get rid of inner ponding, also can get rid of the solid residues such as the part silt that dissolved air water brings.
The delivery port of dissolved air water separator supporting can install out water pump, is controlled the water level of dissolved air water separator inside by the flow controlling water pump, and adapts to the change of amount of inlet water.
Many valves are preferably internally piloted valve, the preferred VFC of Flow-rate adjustment going out water pump regulates, internally piloted valve with go out water pump and be connected respectively and be controlled by self-con-tained unit, self-con-tained unit separately has many holding wires to be connected to temperature sensor (or thermometer) on knockout drum and level sensor (or water-level gauge), experiences and transmits the liquid level data in water temperature and knockout drum.By control and the adjustment of automatic control dress system, the water level in the water flow of aqueous vapor separating rate, separation degree, hot water, knockout drum is made to obtain Effective Regulation.
Whole device can pass through automatic dispatching, makes the pump head of geothermal well, flow, and the lift of hot water variable frequency pump, flow, and the temperature of dissolved air water is operated in optimum condition and optimal balance point, realizes heating efficiency and maximizes.Heated by natural gas is continuous or interval work mode, ensures that isolated Water Soluble Gas can be burnt in time, does not have Water Soluble Gas emptying, and can realize unmanned and digitlization geothermal heating.
Integration knockout drum, neat gas burner, heat exchanger components etc. can be arranged on an integral skid block, convenient mobile and with the in-site installation of geothermal well, reduce in-site installation and connect workload, reduce installation process to the impact of nearby residents.
Beneficial effect:
The present invention is exactly the natural gas by isolating in Water Soluble Gas, and natural gas is used for heating the hot water from underground heat at once, does not need to carry out natural gas storing and transport to isolated, adds security, decrease investment.The natural gas of burning improves geothermal water temperature, adds calorie value and the grade of underground heat, decreases amount of groundwater mining, reduces and promotes dissolved air water and recharge dissolved air water power consumption, add economic performance.And be separated later underground water natural gas content and greatly reduce, decrease the natural gas leaking of underground heat in use procedure, add the safety in utilization to dissolved air water underground heat.The impact of natural gas volatilization on environment that isolated natural gas passes through to have burnt less, adds environmental benefit.
The present invention solves the comprehensive utilization of dissolved air water, realizes geothermal energy resources and maximizes, improve economic benefit.
Natural gas is separated in system immediately with water, immediately burns, and reduces potential safety hazard and the safety measure investment of natural gas storing.In dissolved air water, the separation of natural gas is greater than 80%, even reaches the separate targets of more than 95%.Heating fuel, without the need to outer confession, is saved use cost and makes full use of natural resources.
