Description
Technical field
This utility model belongs to molecular sieve natural QI prostration water installations technical field, specifically a kind of day with fore filter
Right gas drying device.
Background technology
Molecular sieve natural QI prostration water installations, are mainly divided to two processes in use；1st, dehydration, both molecular sieve water suctions,
Gas dehydration process.2nd, regenerative process, both molecular sieve dehydration, regeneration gas (partially dried natural gas) water absorption course.In dehydration
And impurity during regenerative process in natural gas can cause molecular sieve to block, reduce dehydrating effect or directly result in molecular sieve losing
Dehydrating function.
In dehydration, molecular sieve is dehydrated under the operating temperature of room temperature or a little higher than room temperature, and regenerative process,
Molecular sieve maximum operating temperature can reach more than 230 DEG C.Molecular sieve is a kind of alkali metal aluminosilicate, frequently temperature, aqueous
Amount change can cause molecular sieve, and especially when dehydration and regenerative process conversion frequency are too fast, molecular sieve is particularly tight
Weight.These molecular sieve powders are possible in regenerative process from the drying tower newly entered equipped with molecular sieve, and then block molecule
Sieve.
During regenerative process, need to ensure that with supercharger natural gas is stably flowed to and flow during regenerating molecular sieve, and be pressurized
Machine operationally occurs the situation of abrasion, produces certain impurity, and these impurity all can be flowed in molecular sieve with natural gas, be entered
And block molecular sieve.Three cases above will all cause molecular sieve to block, and lose dehydrating function, reduce service life.
Content of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of natural air dry with fore filter
Dry device.
This utility model solves its technical problem and takes technical scheme below to realize：
A kind of natural gas drying device with fore filter, including pipeline valve, pipeline valve is by pipeline and pre- place
The import connection of reason separator, the outlet of pretreatment separator are connected with the import of fore filter by pipeline, prefilter
The outlet of device is connected with the import of molecular sieve drying tower by pipeline, and the outlet of molecular sieve drying tower is by pipeline and egress filtering
The import connection of device, the outlet of outlet filter are connected with downstream user pipeline, meanwhile, at the import and export two ends of outlet filter
It is parallel with the natural gas in series by supercharger and heater and recharges regeneration pipeline, at import and the pre- place of molecular sieve drying tower
Discharge pipe is cooled down between the import of reason separator after pipeline is connected with the regeneration being made up of cooler.
And, the pipeline valve is specifically using double high flanged ball valves.
Advantage of the present utility model and good effect are：
This utility model simple structure, low cost, take up an area little, simple to operate, safe and reliable to operation, effectively extend point
In son sieve drying tower, the service life of molecular sieve, reduces cost of equipment maintenance.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
This utility model is implemented to be further described below in conjunction with accompanying drawing, following examples are descriptive, are not
Determinate, it is impossible to which that protection domain of the present utility model is limited with this.
A kind of natural gas drying device with fore filter, as shown in figure 1, including pipeline valve 8, pipeline valve passes through
Pipeline is connected with the import of pretreatment separator 1, isolates large granular impurity and part moisture, pretreatment by pretreatment separator
The outlet of separator is connected with the import of fore filter 2 by pipeline, is filtered out by fore filter and can be blocked molecular sieve
Impurity, the outlet of fore filter are connected with the import of molecular sieve drying tower 3 by pipeline, are removed by molecular sieve drying tower natural
Moisture in gas, the outlet of molecular sieve drying tower are connected with the import of outlet filter 4 by pipeline, the outlet of outlet filter
It is connected with downstream user pipeline, meanwhile, it is parallel with the import and export two ends of outlet filter and is connected by supercharger 5 and heater 6
The natural gas of composition recharges regeneration pipeline, and dry natural gas flows into molecular sieve drying after charger boost and heater heating
Tower, makes regenerating molecular sieve to molecular sieve heating, passes through between the import of molecular sieve drying tower and the import of pretreatment separator
Pipeline cools down discharge pipe after being connected with the regeneration being made up of cooler 7, and cooler will recoil out during regenerating molecular sieve
High temperature, return to after the cooling of high wet gas and enter in pretreatment separator next circulation.
In of the present utility model being embodied as, the valve is using double high flanged ball valves.
Working procedure of the present utility model：
When dewatering work is carried out, natural gas enters pretreatment separator from equipment importation to this device, separates bulky grain miscellaneous
Enter in fore filter after matter and part water, the impurity that can block molecular sieve is filtered out by fore filter.Finally natural
Gas supplies downstream pipe network by egress filtering gas after moisture gone out by molecular sieve drying tower.
During this device conducting molecule sieve reproduction operation, the partially dried natural gas of outlet by charger boost and is added
Molecular sieve drying tower being flowed into after hot device heating, regenerating molecular sieve being made to molecular sieve heating, finally the natural gas containing moisture is through cold
But enter in pretreatment separator after device cooling, then enter after fore filter filters out impurity dry in drying tower.
