Description

余热驱动双吸附床化学吸附的渔船用制冰机技术领域本发明涉及的是一种用于船舶辅机技术领域的制冰机,具体是一种余热驱动双吸附床化学吸附的渔船用制冰机。 Heat driven dual adsorbent bed vessels involved in chemisorption icemaker Technical Field The present invention is a marine ice maker for auxiliary technical field, in particular a heat driven dual adsorbent bed with ice fishing chemisorption machine. 背景技术目前,我国沿海中小型渔船大都以冰藏保鲜为主,机械制冷保鲜为辅。 BACKGROUND At present, China's coastal fishing is mostly in small and medium sized ice storage preservation-based, supplemented by mechanical refrigeration preservation. 因此, 渔船制冷机是当前中、小型渔船迫切需要装备的设备,开发研制还是集中在蒸气压縮式制冷方式。 Therefore, current fishing refrigerator is in urgent need to equip small fishing equipment, developed concentrated in the vapor compression refrigeration mode. 与此同时,渔船上的柴油机约有30%的热量从尾气排入大气而浪费。 At the same time, about 30% of diesel on board fishing vessels from the exhaust heat into the atmosphere and waste. 若能利用这部分余热来驱动吸附式制冷系统,即可不增加柴油机任何油耗, 仅回收其尾气余热实现制冰,满足渔民的需求。 If we can use this part of the waste heat to drive sorption refrigeration systems, no additional fuel to the diesel engine, which exhaust heat recovery achieved only ice, to meet the needs of the fishermen. 船用吸附制冷设备主要采用水、 氨以及甲醇为制冷剂,其中采用水、甲醇为制冷剂的系统一般采用物理吸附剂, 相对与采用化学吸附剂一氨为工质对的系统而言,制冷量偏小。 Marine adsorption refrigeration equipment, mainly water, methanol and ammonia as a refrigerant, wherein the use of water, methanol as the refrigerant generally use the system physical adsorbent, as opposed to using a chemical adsorbent for ammonia refrigerant systems in terms of cooling capacity too small. 而对于氨系统, 由于氨与铜材料,海水与钢材料之间具有不相容性,所以目前采用氨为制冷剂的系统一般不能采用海水直接冷却,否则会存在严重的腐蚀问题。 For ammonia systems, because of incompatibility between the copper material and ammonia, water and the steel material, currently used in ammonia refrigerant systems generally can not be directly cooled using seawater, otherwise there is severe corrosion problems. 经对现有技术的公开文献检索发现,专利申请号:200310108923.0,名称为: 复合交变热管双吸附床,该专利采用氨为制冷剂,氯化钙为吸附剂。 Disclosed by the prior art literature search found patent application number: 200310108923.0, entitled: Composite alternating double pipe heat adsorbent bed, this patent uses ammonia as the refrigerant, the adsorbent is calcium chloride. 改双吸附床的加热与冷却形式采用复合交变热管,但由于其双吸附床的加热部分采用烟气直接对热管进行加热,在双吸附床冷却时,烟气阀门关闭,双吸附床的热管加热段是处于冷热交变状态,这样烟气会在双吸附床的热管加热段管路上凝结,形成酸蚀。 Heating and cooling in the form of modified dual adsorbent bed composite alternating heat pipe, but the heating portion of its dual adsorbent bed using flue gas directly to the heat pipe is heated, in the dual adsorbent bed cooling, the flue gas valve is closed, dual adsorbent bed heat pipe heating section is in alternating hot and cold state, so that the flue gas will condense in the dual adsorbent bed section of the heat pipe heating pipeline, forming etching. 另一方面该系统在冷却状态下,控制热管加热段的阀门关闭,这样由于双吸附床部分的热管与热管加热段的热管分别属于两个不同的密闭空间,同时两部分的温度也存在一定的差异,所以热管加热段的压力要高于双吸附床内热管内部的压力,这样不利于系统的安全运行。 On the other hand the system is in the cold state, the control valve of the heat pipe heating section is closed, so that due to the heat pipe heat pipe and heat pipe heating section dual adsorbent bed portion belong to two different sealed space, while the temperatures of the two parts, there are some difference, the pressure heating section of the heat pipe is higher than the pressure inside the heat pipe dual bed adsorption, this is not conducive to safe operation of the system. 发明内容本发明的目的在于克服上述现有技术的不足,提供一种余热驱动双吸附床化学吸附的渔船用制冰机,使加热通道和冷却通道相分离从而解决现有复合交变热管双吸附床中热管由于冷热交变而导致的烟气腐蚀问题,同时减少阀门的数量以提高系统运行的可靠性。 The object of the present invention is to overcome the disadvantages of the prior art described above, there is provided a heat driven dual adsorbent bed chemisorption fishing icemaker, the heating and cooling channels separated channel to solve the conventional adsorbent composite alternating double pipe heat bed heat pipe corrosion problems due to the flue gas caused by alternating hot and cold, while reducing the number of valves to increase the system's reliability. 为了使发生器具有一定的抗摇摆性能,双吸附床与水平方向夹角为15"。本发明是以下技术方案实现的,本发明包括:海水冷凝器,冷却和加热阀门, 双吸附床,壳体,液位控制器,烟气加热器,连接法兰,氨冷凝器,回质管,满液式蒸发器,回质阀。其连接方式为:烟气加热器位于壳体的底部,海水冷凝器设在壳体的顶部,加热阀门设在双吸附床与烟气加热器之间,冷却阀门设在双吸附床与海水冷凝器之间,吸附剂设在双吸附床内,氨冷凝器与双吸附床通过连接法兰相连,满液式蒸发器和氨冷凝器相连,回质阀通过回质管连接左右两个满液式蒸发器,液位控制器设置在壳体内部通过管道和双吸附床相连。海水冷凝器管内部通海水,管路外部空间与壳体构成甲醇冷凝腔,通过冷却和加热阀门的开关来切换对双吸附床的冷却和加热,吸附剂放在双吸附 In order to have some anti sway generator performance, dual adsorbent bed 15 and the angle of the horizontal direction "of the present invention, the following technical solution of the present invention comprising: a water condenser, a cooling and heating valves, dual adsorbent bed, shell body, level controller, GGH, flanges, ammonia condensers, quality control back, flooded evaporator, which is connected to valve mass recovery way: at the bottom of the housing of the gas-gas heater, water a condenser disposed at the top of the housing, a valve is provided between the dual heating adsorption bed gas-gas heater, the cooling valve disposed between the condenser water and dual adsorbent bed, the adsorbent bed is provided in double adsorption, ammonia condensers dual adsorbent bed and connected through a connecting flange, is connected to a flooded evaporator and condenser ammonia, about two mass recovery valve is connected through a flooded evaporator return tube quality, level controller disposed inside the housing and through the pipe dual adsorbent bed is connected to inner tube through the sea water condenser, and the housing space constituting the outer conduit methanol condensation chamber, the cooling and heating are switched dual adsorbent bed for cooling and heating by switching the valves, the adsorbent on the adsorption bis 床内。液位控制器控制水的液位高低,烟气加热器通过烟气来加热水,使水受热蒸发。海水冷凝器管内为海水,管外为热管的工作介质,即甲醇蒸气。甲醇蒸汽在双吸附床的外壁蒸发,带走吸附热,然后在海水冷凝器的表面冷凝。海水冷凝器由于与双吸附床内部的氨气空间为两个不同的空间,所以可以采用铜材,这样即可以防止海水腐蚀,也不会存在氨气对铜材料的腐蚀问题。由于采用了这种新型的冷却方式,海水冷凝器在双吸附床加热过程中,海水可以不切换,只需关闭或开启甲醇蒸汽管路的阀门即可控制对双吸附床的冷却过程。双吸附床的加热采用烟气加热器所产生的水蒸汽来加热,这样可以避免烟气对水直接加热过程中所产生的腐蚀问题。由于采用了这种新型的加热方式,烟气加热器在双吸附床冷却过程中,烟气可以不切换,只需关闭或开 The bed level controller controls the level of the water level, the water heater to heat the flue gas by the flue gas, the water is heated and evaporated. Seawater is seawater condenser tube, an outer tube as the working medium of the heat pipe, i.e., the methanol vapor. Methanol steam dual adsorbent bed outer wall evaporated away heat of adsorption, and then condensed in the condenser surface seawater. Since ammonia water condenser space within the double bed adsorption two different spaces, the copper may be employed, such i.e., seawater corrosion can be prevented, nor the presence of ammonia copper material corrosion problems. As a result of this new cooling, water condenser, heating in a dual adsorbent bed process, water may not be switched off or on just methanol vapor line valve to control the cooling process of the dual adsorption beds. dual adsorbent bed is heated by steam generated by the gas-gas heater for heating, to avoid the fumes generated during the heating of the water directly corrosion problem. As a result of this new heating method, dual adsorbent bed gas-gas heater in the cooling process, the flue gas may not be switched off or simply open 阀门即可控制对双吸附床的加热过程。 本发明与其他发生器相比,所采用的阔门数量大大减少,这有利于系统工作的可靠性,同时可以降低产品的成本,有利于市场推广。本发明工作主要包括两个过程, 一为加热解吸过程。在加热解吸过程中,在烟气加热器的烟气加热作用下,水受热蒸发,此时双吸附床的冷却阀门关闭,加热阀门开启,从烟气发生器中出来的水蒸汽进入双吸附床中央的加热通道,为双吸附床提供热量并使双吸附床的温度上升,当单元管中吸附剂的温度上升到可以解吸的温度后,吸附剂所吸附的氨制冷剂从吸附剂中解吸出来,在冷凝器中冷凝成液体然后进入到满液式蒸发器中。双吸附床的另一个工作过程为冷却吸附过程。 在冷却吸附过程中,加热阀门关闭,冷却阀门开启,甲醇介质在双吸附床的外壁蒸发,带走双吸附床内部吸 Valves to control the heating process of the dual adsorbent bed.
