Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
As shown in FIG. 1, a modular molecular sieve dehydration sledge comprises a pre-filtration separator F-201. The preposed filtering separator F-201 is connected with a differential pressure valve which is connected with a dehydration tower. The dehydration tower comprises a tower A and a tower B which are arranged in parallel. The dehydration tower is connected with a post-filter separator F-202 and an electric heater E-201, the electric heater E-201 is connected with a heat energy recoverer H-202, the heat energy recoverer H-202 is connected with a regeneration gas cooler K-201, and the regeneration gas cooler K-201 is connected with a regeneration gas separator V-202.
Wherein, the electric heater E-201 adopts an explosion-proof electric heater. The regeneration gas cooler K-201 adopts a regeneration gas cooler with the model number of BJS 500-6.4-63-6/19-4. The differential pressure valve is an adjustable differential pressure valve. At least two stages of filter elements are arranged in the front filtering separator F-201 and the rear filtering separator F-202.
The working process of the utility model comprises an adsorption process, a heating regeneration process and a cold blowing process.
An adsorption process: the raw material gas (incoming gas) firstly enters a preposed filtering separator F-201 of a molecular sieve dehydration sledge for filtering, then the pressure of the incoming gas is reduced through a differential pressure valve, and then the incoming gas enters a dehydration tower (tower A/tower B) for dehydration. The normal pressure water dew point of the natural gas dehydrated by the molecular sieve is less than or equal to minus 60 ℃. And the gas discharged from the dehydration tower enters a post-filter separator F-202 to remove impurities and dust carried in the natural gas and then enters a downstream system. The impurities in the front-mounted filter separator and the rear-mounted filter separator enter a closed drainage system through a sewage discharge pipeline.
Heating and regenerating processes: molecular sieve regeneration is a wet gas regeneration process. A regenerated gas is led out from the feed gas of the main path by the gas passing through the preposed filtering separator F-201, the regenerated gas is preheated by a heat energy recoverer H-202, heated by an electric heater E-201, heated to the set regeneration temperature (170 plus 180 ℃) of the molecular sieve, enters from the bottom of a molecular sieve tower, heats and regenerates the saturated molecular sieve in the bed layer, the regenerated moisture is pre-cooled by the heat energy recoverer H-202, the regenerated gas cooler K-201 is cooled to the temperature of the incoming gas and then enters a regenerated gas separator V-202 for gas-liquid separation, and the separated gas returns to the outlet end of the differential pressure valve.
And (3) cold blowing process: after regeneration is finished, the molecular sieve temperature is high, so that the water adsorption capacity is reduced, and the molecular sieve dehydration tower bed layer needs to be cooled by cold blowing. The cold blowing gas is still the gas led out from the main path feed gas, and the cold blowing gas directly enters from the upper part of the molecular sieve tower to cool the high-temperature molecular sieve in the bed layer until the molecular sieve in the bed layer of the molecular sieve dehydration tower reaches the normal working temperature. The cold blowing gas out of the molecular dehydration tower (tower A/tower B) is cooled to the temperature of the incoming gas by a regeneration gas cooler K-201 and then enters a regeneration gas separator V-202 for gas-liquid separation, and the separated gas returns to the outlet end of the differential pressure valve.
The utility model discloses simple structure, reasonable in design, the practicality is stronger, carries out the modularization installation, is favorable to dwindling area, energy saving and emission reduction simultaneously.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
