Abstract
The utility model relates to a portable trace oxygen analyzer with a dry purifier for polyformaldehyde production, which comprises a trace oxygen analyzer, wherein an air intake is formed at the side surface of the trace oxygen analyzer. A spiral bracket is formed by winding a metal pipe, wherein one end of the spiral bracket is communicated with the air intake, and the other end of the spiral bracket is connected with a dryer; the dryer arranged in the spiral bracket is a straight drying tube of which the head is provided with a ball bubble, and the drying agent is filled in the ball bubble. The portable trace oxygen analyzer provided by the utility model widens the application range of the portable trace oxygen analyzer for chemical devices, prevents the oxygen sensor from being damaged by a processing medium, prolongs the service life of the instrument, and reduces the maintenance cost.
Description
Technical field
The utility model belongs to analytical instrument, relates in particular to a kind of portable micro oxygen analyzer.
Background technology
Trace oxygen analyzer is used for the chemical plant installations pipeline, tower has pressure-fired micro-oxygen content on-line determination, have to take a sample, and on-the-spot reading, analysis speed is fast, and accuracy is high, can measure ppm level oxygen content.
Lambda sensor requires very strictness to the analytical gas cleanliness factor in the trace oxygen analyzer, and requiring does not have particle, liquid, condensation product, grease etc. in the gas, otherwise the instrument lambda sensor can stop up or damage.And chemical plant installations drives the initial stage can have water or condensed fluid and other impurity in pipeline, the equipment, can't use trace oxygen analyzer to carry out on-line determination, influences the Instrument measuring range of application, can't in time for the chemical plant installations operation online service data be provided.
The utility model content
The utility model is for enlarging the measurement range of portable micro oxygen analyzer; Be applicable to the on-line analysis of chemical plant installations anywhere micro-oxygen content; Solve because determination object has and influences oxygen analyzer sensor impurity and unmeasured application limitations provides a kind of polyoxymethylene production that has the dry decontamination device to use the portable micro oxygen analyzer.
Adopt following technical scheme in order to solve the problems of the technologies described above: the portable micro oxygen analyzer is used in a kind of polyoxymethylene production that has the dry decontamination device, comprises microanalyser, and the microanalyser side is provided with and connects gas port; Process a helical stent with the metal tube winding; One end of helical stent with connect gas port and be communicated with, the other end of helical stent is connected with exsiccator, exsiccator is arranged in the helical stent; Exsiccator is the straight type drying tube that head is provided with the ball bubble, and is desiccant-filled in the ball bubble.
The lime chloride of filling 1/3 in the described straight type drying tube, the mouth of pipe is plugged with absorbent cotton.
Described helical stent is connected through 1/8 cutting ferrule with connecing between the gas port.
Filling foamed plastics between described straight type drying tube and the helical stent, and, be fixed on the microanalyser surface then with firm box parcel.
Described metal tube is copper pipe or steel pipe.
The utility model has enlarged the portable micro oxygen analyzer in the chemical plant installations usable range; The protection lambda sensor is avoided the infringement of processing medium, has prolonged instrument serviceable life; Reduced maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the portable micro oxygen analyzer is used in a kind of polyoxymethylene production that has the dry decontamination device, comprises microanalyser 1; Microanalyser 1 side is provided with and connects gas port 2, twines with copper pipe and processes a helical stent 3, and an end of helical stent 3 is communicated with through 1/8 cutting ferrule with connecing between the gas port 2; The other end of helical stent 3 is connected with straight type exsiccator 4, and straight type exsiccator 4 is arranged in the helical stent 3, and the head of straight type exsiccator is provided with the ball bubble; The lime chloride of filling 1/3 in the ball bubble; The mouth of pipe is plugged with absorbent cotton, and absorbent cotton is fortress too tight not, and too tight gas can't get out.Filling foamed plastics between straight type drying tube and the helical stent, also filling foamed plastics between helical stent and the microanalyser, and, be fixed on the microanalyser surface then with firm box parcel, in order to avoid straight type drying tube shakes shatter.
Copper pipe then directly connects if can be directly connected in the straight type drying tube; If can not directly connect, then avoid the use of plastic tube, rubber tube, leather hose etc. and make it to connect.When doing gas analysis, connect, and displacement, sampling in the scene, analyze and get final product with external emulsion tube.
The employing cutting ferrule connects, and impermeability is good, is convenient to buy subsequent use or replacing; Copper pipe or steel pipe satisfy the precision measurement requirement; Straight type drying tube simple structure, and be convenient to change; Applied widely, if the medicine that has specific demand only need change in the straight type drying tube gets final product; The gas circuit pipeline serves as the effect of support simultaneously, only need do shockproof processing and get final product; It is strong to transform back parts interchangeability, and failure rate is low, is beneficial to maintenance, uses reliable, compact, attractive in appearance.
