Technical field
The utility model relate to a kind of by heat exchanger with refrigeration system, electrically separate, the Split type anti-explosion type cooling driers that hydrogen field requires explosive-proof grade can be met, genus cooling driers manufacture field.
Background technology
1, CN203147988U, title " explosion-proof type mine heat recovery air conditioner ", include compressor, four-way change-over valve, gas-liquid separator, oil eliminator, pressure fan, two finned heat exchangers and exhaust blower, described compressor, gas-liquid separator, oil eliminator, two finned heat exchangers form refrigerant circulation loop, it is characterized in that: described exhaust blower is explosion-proof type exhaust blower; The refrigeration system pipeline of wind through four-way change-over valve is switched refrigeration or heats by described pressure fan, sent in mine operation district by wind new after a finned heat exchanger heat exchange, the gas in described mine operation district is carried out heat exchange by explosion-proof type exhaust blower discharged to another finned heat exchanger.
2, the operation principle of existing freezing type drier (abbreviation cooling driers) is: according to freeze drying principle, Compressed Gas containing a large amount of saturated vapor is carried out forced cooling, because the amount of steam in Compressed Gas is determined by the temperature of Compressed Gas: when keeping compression pressure substantially constant, reduce the temperature of Compressed Gas, thus make a large amount of water vapours in Compressed Gas be in hypersaturated state, under hypersaturated state, water recovery becomes liquid water droplet, and dust, through carbonated drink separation equipment, moisture and dust are separated and is discharged by automatic water trap, thus obtain dry Compressed Gas.Gas pressure dew point after cooling driers process can reach 2-10 DEG C.Cooling driers includes the refrigeration system of a circulation, and comprise cold medium compressor, condenser, its refrigerant is freon.The following cold medium compressor of existing refrigerating capacity 80KW does not have explosion-proof type, and the above cold medium compressor explosive-proof grade of refrigerating capacity 80KW only has dx II BT4, and this explosive-proof grade is still inadequate in hydrogen field.
Summary of the invention
Purpose of design: avoid the weak point in background technology, designs a kind of Split type anti-explosion type cooling driers meeting hydrogen field and require explosive-proof grade.
Design: in order to realize above-mentioned purpose of design.The present invention is in structural design: 1, split explosion-proof type cooling driers basic functional principle and traditional cooling driers basically identical, after utilizing refrigeration system special gas to be cooled to certain dew-point temperature, precipitated phase answers contained moisture content, and discharged by draining valve, thus make the dry dew point required for gas acquisition.Tradition cooling driers collecting exchanger, electrically, refrigeration system is integrated, split explosion-proof type cooling driers is with refrigeration system, electrically separate by heat exchanger, heat exchanger section is not charged, be placed in explosion-proof area, refrigeration system and be electrically a casing, is placed on non-explosion-proof area, like this to refrigeration compressor with electrically do not have requirement of explosion proof, make integral device have more security, do not have influence on again the effect of equipment use.2, split explosion-proof type cooling driers adopts baffle plate, silk screen Despumation device separating and condensing water, recycling Action of Gravity Field principle collects condensed water, because environment is special, condensed water can not directly be got rid of, therefore set up water tank, it is equipped with liquid level visor, manual drainage stop valve, ensure that internal tank gas does not leak, thus solve safety dumping condensation water problem.
Technical scheme: a kind of Split type anti-explosion type cooling driers, heat exchanger is with refrigeration system, electrically separate, and heat exchanger is not charged, is placed in explosion-proof area, refrigeration system and be electrically a casing, is placed on non-explosion-proof area.
The utility model compared with background technology, one be the utility model by heat exchanger with refrigeration system, electrically separate, special gas has requirement field to explosive-proof grade can be used in, solve the defect that traditional freezing type drier can not be used for explosion-proof area; Two is condensed water process, and split explosion-proof type cooling driers is provided with two cover refrigerant Pressure gauges, heat exchanger section and refrigerant system feature each a set of, the ruuning situation of so more intuitive embodiment refrigeration system.
