Abstract
The utility model discloses a corrosion monitoring piece hanger of a methanol recycling tower, and the corrosion monitoring piece hanger is designed for monitoring the corrosion velocity and the corrosion type of the methanol recycling tower by using a weight loss method. A clamp of the piece hanger is fixedly clamped on a tower plate overflowing dam; a horizontally arranged piece hanging bracket is arranged at the bottom of a clamping plate inside the dam of the clamp; the upper end surface of the piece hanging bracket is connected with a horizontal hung piece; the bottom end of the clamping plate outside the dam of the clamp is connected with a screw rod; the bottom end of the screw rod is connected with an independent piece hanging bracket; the upper end surface of the independent piece hanging bracket is connected with an independent horizontal hung piece; and the side surface of the independent piece hanging bracket is connected with an independent vertical hung piece. The corrosion velocity of the top surface, the bottom surface and the tower wall of the methanol recycling tower is monitored through the horizontal hung piece, the independent horizontal hung piece and the vertical hung piece in a weight loss mode, and the corrosion type is determined according to the corrosion morphology and the components of surface products of the surfaces of the hung pieces; and the piece hanger is simple in structure, comprehensive in monitoring and low in manufacturing cost, and the corrosion monitoring on the methanol recycling tower is further improved, therefore, the piece hanger is applicable to corrosion monitoring on various plate-type towers.
Description
Technical field
The utility model relates to a kind of methanol distillation column corrosion monitoring lacing film device, belongs to corrosion detection technique field.
Background technology
In the gas-field exploitation process, often in flow line, inject methyl alcohol, to suppress the generation of gas hydrate from well head.But owing to developing rapidly of natural gas extraction, this injection mode will produce a large amount of sewage containing methanols.In order to protect environment and to save cost, must recycle methyl alcohol.Contain a large amount of metallic ions, dissolubility CO in the sewage containing methanol
2, H
2S sour gas, white oil and machine are assorted, understand heavy corrosion pipeline and methanol distillation column, influence the organic efficiency and the operation life of equipment.At present, generally adopt corrosion thinning amount, resistance corrosion probe and the electrochemistry noise of ultrasonic thickness test method monitoring methanol distillation column,, seldom adopt weight loss method to monitor with hydrogen probe on-line method monitoring corrosion rate.
Summary of the invention
The purpose of this utility model is to provide a kind of methanol distillation column corrosion monitoring lacing film device, and it utilizes the corrosion rate of weight loss method monitoring methanol distillation column, improves the corrosion monitoring of methanol distillation column.
Concrete technical scheme of the present utility model is as follows:
The clamper fixed clamp of this lacing film device is on the column plate overflow weir.The inner splint bottom, weir of clamper is horizontally disposed lacing film support, and lacing film support upper surface connects horizontal lacing film; External splint bottom, the weir connecting screw rod of clamper.The screw rod bottom connects independent lacing film support, and independent lacing film support upper surface connects the independent horizontal lacing film, and the side connects independent vertically lacing film.Be provided with neonychium between the weir external splint of outer weir face of column plate overflow weir and clamper.
The utility model is determined corrosion type by the corrosion rate of horizontal lacing film, independent horizontal lacing film and the weightless monitoring of vertical lacing film methanol distillation column column plate end face, bottom surface and tower wall according to the erosion profile and the surperficial product composition on lacing film surface.The utility model is simple in structure, monitoring is comprehensive, cheap, can further improve the corrosion monitoring of methanol distillation column, be applicable to the corrosion monitoring of various plate columns.
Description of drawings
Fig. 1 is a methanol distillation column corrosion monitoring lacing film device structural representation.
Embodiment
With reference to Fig. 1 embodiment of the present utility model is further specified:
