Description
Technical field
The utility model provides a kind of acid solution purifier of sub-boiling distillation, belongs to testing equipment and material analysis technical field.
Background technology
In the material analysis field, comprise that the multiple inorganic acid of nitric acid, hydrochloric acid and hydrofluoric acid is used as the decomposing agents of sample.For trace in many materials and trace constituent analysis, the purity of these decomposing agents directly has influence on analytical accuracy.The purity level of all ingredients that is adopted in the test becomes a key factor of discriminant analysis result reliability.At present, many laboratories are directly from the high high purity reagent of reagent company purchasing price, and perhaps the various forms of purification devices of inner employing carry out purifying to inorganic acid in the laboratory.In these purification devices, the sub-boiling distillation system that some well-known instrument companies produced is reasonable in design, and the reagent treatment amount is moderate, but structure is complicated, and very high to the preparation material requirements of instrument, the instrument price is more than 50,000 yuan.Though also have the acids reagent purifying plant of some manufacturer production simple in structure, but there is defective in the actual use: adopt cylinder type metal electric heating sheets to be enclosed within outside the reagent bottle acid is heated, work long hours or heating and temperature control improper, the reagent bottle deliquescing can occur and cause the phenomenon of electrical heating cover landing.The reagent bottle that feeds acid vapor is placed in the tank with certain gradient, and cooling water can only flood reagent bottle fraction volume, because the contact-making surface of acid vapor and cooling water causes condensation effect poor for a short time, sour purification efficiency is low; While, as cooler, water level was subject to the influence of running water flow, needs personnel on duty with uncovered tank.So it is simple relatively to design, prepare a cover apparatus structure, the sub-boiling distillation device that it is suitable that stable performance goes out sour efficient simultaneously is the problem that we will solve emphatically.
The utility model content
The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, simple in structure, operating characteristics is stable, cost is low acid distillation purifier.Its technical scheme is:
A kind of acid distillation purifier, comprise support, hold the reagent bottle for the treatment of purified acid solution, hold the reagent bottle of distillation and be connected in tube connector between two reagent bottles, it is characterized in that: two reagent bottles are the perfluoroethylene-propylene material and make, be transparence, support is a reverse V-shaped support, the support top is the circular arc type tube connector, tube connector adopts perfluoroalkyl vinyl ether copolymer or polytetrafluoroethyltubing tubing to make, two ends band internal thread, corresponding with hold the reagent bottle for the treatment of purified acid solution, the reagent bottle that holds distillation is threaded, hold water(-cooling) jacket of reagent bottle outside suit of distillation, the below of water(-cooling) jacket and top are respectively equipped with the entrance and exit of cooling water, and reagent bottle side top is provided with the infrared lamp of an adjustable power.
Described acid distillation purifier, the centerline length scope 6～10cm of tube connector, the bore of two reagent bottles is 2～3cm.
Described acid distillation purifier, two reagent bottle capacity are 500ml or 1000ml.
Described acid distillation purifier, infrared lamp connects pressure regulator 9, voltage adjusting range 70V～85V.
Its operation principle is: adopt controlled infrared lamp Continuous irradiation, the purified acid solution for the treatment of in the one end reagent bottle is evaporated being lower than under the boiling temperature, acid vapor enters into the reagent bottle that the other end is set with water(-cooling) jacket by tube connector, realizes the high-efficiency condensation of acid vapor with water-cooling pattern.Through behind the single flash, most of tenor can be reduced to below the PPB level in the acid.
The utility model compared with prior art has following advantage:
1, holding water(-cooling) jacket of reagent bottle outside suit of distillation, cooling water fully contacts with acid vapor by the bottle wall, and the condensation efficiency height is difficult for being subjected to cooling water flow to influence.
2, with infrared lamp as radiation source, realize the controlled evaporation of acid solution, can keep the safety in production continuously.
3, package unit is simple in structure, and operating characteristics is stable, and experimentation cost is low.
4, because all parts that contact with steam are the fluoroplastics material, this device can use does not for a long time have corrosion and pollution, can be used for the purifying preparation than the low boiling inorganic acid such as hydrofluoric acid, nitric acid and hydrochloric acid.
