Description
(一)技术领域(1) Technical field
本实用新型高效酸蒸气吸收装置，适用于各种湿法消化的酸蒸气吸收试验。The utility model has a high-efficiency acid vapor absorption device, which is suitable for various acid vapor absorption tests of wet digestion.
(二)技术背景(2) Technical background
酸吸收装置是化学，化工、生化、医学、教学等领域迫切需要的一种装置，当前在实验室需要进行湿法消化时，大都是使用通风装置将消化产生的酸蒸气直接排放到大气当中，对大气产生的污染特别严重，而且酸蒸气在通风装置上非常容易凝结，从而很快就腐蚀了通风装置。The acid absorption device is a device that is urgently needed in the fields of chemistry, chemical industry, biochemistry, medicine, teaching, etc. At present, when wet digestion is required in the laboratory, most of them use ventilation devices to directly discharge the acid vapor generated by digestion into the atmosphere. The pollution of the atmosphere is particularly serious, and the acid vapors are very easy to condense on the vents, which quickly corrode the vents.
湿法消化样品处理量比较大，测定所需要的仪器灵敏度要求不高，价格比较便宜，是基层实验室测定样品比较好的前处理方法。但是因为其对大气的污染比较严重，所以普及起来也有些困难。该吸收装置的出现，对湿法消化的样品前处理方法将起到巨大的推动作用。The wet digestion method has a relatively large amount of sample processing, the sensitivity of the instruments required for the determination is not high, and the price is relatively cheap. It is a better pretreatment method for the determination of samples in grassroots laboratories. However, because of its serious air pollution, it is difficult to popularize it. The appearance of this absorption device will play a huge role in promoting the sample pretreatment method of wet digestion.
(三)本吸收装置实用新型高效内容(3) High-efficiency content of the utility model of the absorption device
本吸收装置的目的是提供一种实用的、高效的酸蒸气吸收装置。The purpose of this absorption device is to provide a practical and efficient acid vapor absorption device.
本吸收装置解决上述技术所采用的方案是：The scheme adopted by this absorption device to solve the above-mentioned technology is:
本吸收装置由反应瓶、第一冷凝球、第二冷凝球、吸收瓶组成，反应瓶由耐高温材料制成，用于消化样品。第一冷凝球下端用磨口玻璃塞与反应瓶相连接，可以防止漏气；第一冷凝球进气口内凹，周围形成一环形凹槽，在该球内壁上冷凝的酸液沿球壁流下，汇入凹槽内，再由凹槽下面的排气、液口经耐高温、耐酸碱管进入第二冷凝球(大约有60％的酸蒸气在第一冷凝球内被液化)。第二冷凝球既起到了进一步冷凝的作用，又可以有效地缓解反应剧烈时酸气冲出吸收液，降低吸收率，还可以防止吸收瓶内的吸收液倒吸入反应瓶内。第二冷凝球与吸收瓶之间由胶塞相连接，结构比较稳定。第二冷凝球出气口正好稍低于吸收瓶内液面高度，吸收瓶的液面上方紧挨液面处有一个排废液口，吸收液吸收酸蒸气和冷凝液后升高的部分会从此处排出，从而可以维持吸收液面的高度基本不变，这样使得反应装置内的压强不会增大，也可以有效地防止吸收液的倒吸(原理是：当吸收液开始倒吸入第二冷凝球时，液面稍一下降，便会低于第二冷凝球导管的下端口，这时，会有气体被吸入第二冷凝球，从而使倒吸的吸收液重新流回吸收瓶中。)。吸收瓶内使用氢氧化钠溶液做吸收液，对酸蒸气的吸收会非常容易。The absorption device is composed of a reaction bottle, a first condensation ball, a second condensation ball and an absorption bottle. The reaction bottle is made of high temperature resistant material and is used for digesting samples. The lower end of the first condensation ball is connected to the reaction bottle with a ground glass plug to prevent air leakage; the air inlet of the first condensation ball is concave, and an annular groove is formed around it, and the acid liquid condensed on the inner wall of the ball flows down along the ball wall , into the groove, and then enter the second condensation bulb through the exhaust and liquid ports below the groove through high temperature resistant, acid and alkali resistant pipes (about 60% of the acid vapor is liquefied in the first condensation bulb). The second condensation ball not only plays the role of further condensation, but also can effectively alleviate the acid gas rushing out of the absorption liquid when the reaction is violent, reducing the absorption rate, and can also prevent the absorption liquid in the absorption bottle from being sucked into the reaction bottle. The second condensation bulb is connected with the absorption bottle by a rubber stopper, and the structure is relatively stable. The gas outlet of the second condensation ball is just slightly lower than the liquid level in the absorbing bottle, and there is a waste liquid outlet above the liquid level in the absorbing bottle, and the rising part of the absorbing liquid after absorbing acid vapor and condensate will flow from here Discharge at the place, so that the height of the absorption liquid level can be maintained basically unchanged, so that the pressure in the reaction device will not increase, and the suction back of the absorption liquid can be effectively prevented (the principle is: when the absorption liquid starts to suck back into the second condensation When the liquid level drops slightly, it will be lower than the lower port of the second condensation bulb, at this time, some gas will be sucked into the second condensation bulb, so that the sucked absorption liquid will flow back into the absorption bottle.) . Sodium hydroxide solution is used as the absorption liquid in the absorption bottle, and the absorption of acid vapor will be very easy.
本吸收装置的积极效果：Positive effects of the absorption device:
1.为采用湿法消化的试验提供了一种方便实用的吸收装置。1. A convenient and practical absorption device is provided for the experiment of wet digestion.
2.极大地减少了对室内空气和室外大气的污染。2. Greatly reduce the pollution of indoor air and outdoor atmosphere.
3.制造成本低廉，结构简单，固定不需铁架台，冷凝不需用水管，适合于各种实验室的普及和推广。3. The manufacturing cost is low, the structure is simple, no iron frame is needed for fixing, no water pipe is needed for condensation, and it is suitable for the popularization and promotion of various laboratories.
