The principle and feature of the present invention are described below in conjunction with accompanying drawing, the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
As shown in figure 1, the output pipe of the first filter separator 1 divides two-way, all the way directly with the second filter separator 8
Intake line 8A is connected, and in order to prevent back flow of gas, the first filter separator 1 is on the pipeline of the intake line 8A is linked into
It is provided with valve.Another way is switched to the first molecular sieve water separation tower 2, the first three-way pipe 2A other end by the first three-way pipe 2A
Cooler 6 is switched to, the output end of cooler 6 is switched to separator 7 again, and the output end of separator 7 is switched to the first filtering again
The input of separator 1.
It is separated by filtration as shown in figure 1, the other end of the first molecular sieve water separation tower 2 is switched to second using the second three-way pipe 2B
The intake line 8A of device 8, and connected in the second three-way pipe 2B on the pipeline of the second filter separator 8 and set a branch road to be switched to
Micro- supercharging equipment 4, the output end pipeline of micro- supercharging equipment 4 are further divided into two-way, are linked into the two or three by electric heater 5 all the way
Siphunculus 2B, another way are directly connected to second three-way pipe 2B.In the present embodiment, the specifically output end of micro- supercharging equipment 4
It is connected simultaneously with the three-way pipe 2B of electric heater 5 and second by a triple valve.In order to ensure the continuity of whole device work,
The quantity of the first molecular sieve water separation tower 2 is two in the present embodiment, and two the first molecular sieve water separation towers 2 are arranged in parallel, and even
It is identical to connect mode.Second molecular sieve water separation tower 3 is connected in parallel on intake line 8A, specifically, the second molecular sieve water separation tower 3
Intake line is connected by a triple valve with intake line 8A.Valve is provided with the output pipe of second molecular dehydration tower 3.
In order to handle sewage and impurity etc., blow-off pipe 9, and the filter separator of separator 7 and second have been picked out on the first filter separator 1
8 are turned on the blow-off pipe 9.
The function of all parts is as follows in the present invention：
First filter separator 1 and the second filter separator 8 be respectively intended to impurity obtained by removing each in gas and
Dust, the first molecular sieve water separation tower 2 and the second molecular sieve water separation tower 3 are used for loading molecular sieve, carry out dehydration absorption, micro- supercharging is set
Standby 4 are used for being pressurized to resulting regeneration gas, realize recycling for regeneration gas, electric heater 5 is used for heating up to regeneration gas, cold
But device 6 is used for being cooled to regeneration gas, and separator 7 is used for carrying out gas-liquid separation to regeneration gas.
During specifically used, the present invention can be related to adsorption process, thermal regeneration process and cold blowing process.
Adsorption process is the impurity dust in processing unstripped gas, and thermal regeneration process is aqueous vapor that will be adsorbed on molecular sieve etc.
Handled so that molecular sieve disclosure satisfy that the requirement reused.Cold blowing process is to reduce the temperature of molecular sieve, well can
Continue to play the effects such as absorption aqueous vapor.
In adsorption process, unstripped gas is first into the first filter separator 1, is removed by the first filter separator 1
After impurity and dust, it is divided into two-way, enters the first molecular sieve water separation tower 2 all the way and handled, gas after processing and another
The gas mixing that road comes out from the first filter separator 1, and start that downstream unit can be entered.Now be divided into the defeated operating mode of pipe and
CNG operating modes, when operating mode defeated for pipe, close corresponding valve so that mixed gas enters directly into second and is separated by filtration
In device 8, the impurity and dust carried in gas is removed again, then as defeated outside pipe gas.When for CNG operating modes when, close corresponding
Valve so that by passing through the second filter separator 8 after the second molecular sieve water separation tower 3 again, generation meets mixed gas
The gas of CNG standards.
Regeneration to molecular sieve, what is used in the present invention is still dry gas regeneration principle.In embodiment is divided, with parallel connection
Mode two the first molecular sieve water separation towers 2 are set, a positive normal work, another is using dry gas reversely to point in tower
Son sieve is handled, and can be used well again.This setup can ensure that the work of whole device links up.
During thermal regeneration, one is drawn again by branch road from an output pipe of the first molecular sieve water separation tower 2
Anger, the regeneration gas enter electric heater 5 and heated after micro- supercharging equipment 4 is pressurized.By to heater 5
Control so that gas heating is to 220 DEG C -280 DEG C.Heated gas passes through another lower section of the first molecular sieve water separation tower 2
The second three-way pipe 2B enter in first molecular sieve water separation tower 2, the molecular sieve in tower is heated so that absorption
Aqueous vapor etc. depart from, and carried out by the first three-way pipe 2A after subcooler 6 is cooled to come temperature degree, then by separator 7
Gas-liquid separation.Gas after separation returns the input of the first filter separator 1, reenters circulation.
During cold blowing, it is still and one is drawn by branch road from an output pipe of the first molecular sieve water separation tower 2
Regeneration gas, directly pass through the second threeway of another lower section of the first molecular sieve water separation tower 2 after micro- supercharging equipment 4 is pressurized
Pipe 2B is entered in first molecular sieve water separation tower 2, and the molecular sieve in tower is carried out to blow cold cooling, until molecular sieve reaches normal
Operating temperature.Due to the molecular sieve heating by high temperature, the gas temperature passed through is also higher.The gas is passed through by the first three-way pipe 2A
Subcooler 6 is cooled to carry out temperature degree after, then by separator 7 carry out gas-liquid separation.Gas after separation returns the first mistake
The input of separator 1 is filtered, reenters circulation.
By specific implementation, the present invention in operating mode defeated for pipe directly by the second filter separator 8 carry out impurity and
Dust processing, then immediately proceeds to outer defeated pipe network.Relative to existing treatment technology, while meeting to manage defeated index, significantly
Reduce the operation running cost of dehydration device.For CNG operating modes, can be entered again by single second molecular sieve water separation tower 3
Impurity of row and dust processing, you can meet CNG indexs, it is same that there is reduction dehydration device operation relative to prior art
The advantages of expense.
For the molecular sieve in the first molecular sieve water separation tower 2, be by dry gas heating and dry gas directly blow cold mode come
Heated up and cooled, micro- supercharging equipment 4 is provided with piping to ensure the flow direction of dry gas, and realize closed cycle.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
