Description
Technical field
The utility model relates to gas drier, particularly a kind of energy-saving natural gas drying machine.
Background technology
Existing natural gas drying machine is of a great variety, can be divided into preposition drying machine of natural gas and the rearmounted drying machine of natural gas by the installation site, and the pressing force height can divide natural gas high pressure drying machine and natural gas low pressure drying machine.The natural gas drying machine mainly is made up of adsorption tower, compressor, cooler, filter, liquid-gas separator, heater, valve etc.And existing natural gas drying machine exists energy consumption big, and the regeneration waste heat fails to make full use of, and the control point is waited not enough more.
The utility model content
The utility model technical problem to be solved provides a kind of energy-saving natural gas drying machine, and energy consumption is little, and the regeneration waste heat energy makes full use of, and the control point also significantly reduces.
It is following that the utility model solves the technical scheme that its technical problem adopted:
The energy-saving natural gas drying machine of the utility model comprises work loop and regenerative circuit, it is characterized in that: said work loop is made up of the 1st filter, pressure regulator valve, the 1st adsorption tower and the 2nd filter successively; Said regenerative circuit is by be made up of the 3rd adsorption tower, heater, the 2nd adsorption tower, cooler and liquid-gas separator successively, and the air inlet branch road of regenerative circuit is connected between the 1st filter in work loop, the pressure regulator valve.
The beneficial effect of the utility model is, energy consumption is little, makes full use of the regeneration waste heat, and the regeneration cycle system need not to add any circulation power, so can reduce the electric energy loss of natural gas drying machine effectively; Dry gas is regenerated, and has avoided the second adsorption of molecular sieve, improves natural finished product gas makings greatly; Greatly reduce at the control point, has improved the stability of equipment greatly; Drying system has no loss to unstripped gas, and the rate of recovery can reach 100%.
Description of drawings
This specification comprises like next width of cloth accompanying drawing:
Fig. 1 is the structural representation of the energy-saving natural gas drying machine of the utility model.
Parts shown in the figure, toponym and pairing mark: the 1st filter 1, pressure regulator valve the 2, the 2nd filter 3, heater the 4, the 1st adsorption tower the 5, the 2nd adsorption tower the 6, the 3rd adsorption tower 7, liquid-gas separator 8, cooler the 9, the 1st four way ball valve the 10, the 2nd four way ball valve the 11, the 3rd four way ball valve 12.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
With reference to Fig. 1, the energy-saving natural gas drying machine of the utility model comprises work loop and regenerative circuit.Said work loop is made up of the 1st filter 1, pressure regulator valve the 2, the 1st adsorption tower 5 and the 2nd filter 3 successively.Said regenerative circuit is by being made up of the 3rd adsorption tower 7, heater the 4, the 2nd adsorption tower 6, cooler 9 and liquid-gas separator 8 successively, and the air inlet branch road of regenerative circuit is connected between the 1st filter 1, pressure regulator valve 2 in work loop.Pending natural gas at first through the 1st filter 1, control valve 2, through behind the 2nd four way ball valve 11, gets into the 1st adsorption tower 5 again, through four way ball valve 13, arrives filter 3 at last, goes out finished product gas at last.Regeneration gas gets into the 3rd adsorption tower 7, heater the 4, the 2nd adsorption tower 6 in order, and then to cooler 9, arrives liquid-gas separator 8 at last.The utility model makes full use of the regeneration waste heat, and energy consumption is little, and the regeneration cycle system need not to add any circulation power, so can reduce the electric energy loss of natural gas drying machine effectively.Dry gas is regenerated, and has avoided the second adsorption of molecular sieve, improves natural finished product gas makings greatly.
When the 1st adsorption tower 5 carried out drying, under the control of application valve body, the 3rd adsorption tower 7, heater the 4, the 2nd adsorption tower 6, cooler 9, liquid-gas separator 8 formed the enclosed regenerative circuits.To make regenerative circuit produce pressure reduction with the work loop by pressure regulator valve 2 pressure regulation be that kinetic energy makes gas flow to heater to gas in the regenerative circuit, and under the effect of heater 4, temperature raises rapidly; Take heat to the 2nd adsorption tower 6, the molecular sieve temperature in the tower is elevated to a certain degree, separate out the moisture that has been adsorbed; High temperature drying gas by flowing is taken away to cooler 9, and temperature is reduced to about 40 degree rapidly, condensation of moisture Cheng Shui wherein; Separate by liquid-gas separator 8, from blowoff valve, discharge.The certain hour that so moves in circles, the molecular sieve of saturated suction is activated regeneration, possesses the ability of adsorption moisture once more, has not only effectively practiced thrift electric energy, has promoted the quality of finished product gas simultaneously again.
With reference to Fig. 1, the branch road between the 2nd adsorption tower 6 inlet ends of the air inlet branch road in said work loop, the 1st adsorption tower 5 connects through the 2nd four way ball valve 11.The air inlet branch road of regenerative circuit, to the branch road of cooler 9 be connected through the 1st four way ball valve 10 to the 2nd four way ball valve 11.The branch road of giving vent to anger of the branch road of work loop to the 2 filters 3, the give vent to anger branch road and the heater 4 of the 2nd adsorption tower 6 is connected through the 3rd four way ball valve 13.The setting of the 1st four way ball valve the 10, the 2nd four way ball valve the 11, the 3rd four way ball valve 12 greatly reduces the control point of drying machine, has improved the stability of equipment.
Some principles of the above energy-saving natural gas drying machine of the utility model that just explains through diagrams; Be not be to the utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
