Description
Technical field
The present invention discloses a kind of natural gas line corrosion inhibiter coating device, the device of filming especially for high sulfur-bearing moisture gathering line corrosion inhibiter.
Background technology
For the acid gas pipeline that contains hydrogen sulfide and titanium dioxide, having under the hydrops existence condition, can cause the electrochemical corrosion that pipeline is serious, cause tube wall attenuate even perforation, cause poisonous medium to leak and initiation poisoning or accidents such as burning, blast.Usually adopt the corrosion inhibiter of in pipeline, regularly annotating to film in the actual industrial production and prevent pipeline corrosion.Promptly through to adopting coating device, corrosion inhibiter is fully contacted with inside pipe wall, corrosion inhibiter combines through special close metallicity chemical b ` and pipe inner metal surface strongly, forms layer protecting film.
United States Patent (USP) 4425385 has been mentioned a kind of rotary-type coating device.This device is a cylinder, and periphery is equipped with spiral vane, and when device was promoted to advance by gas in pipeline, the air-flow in the spiral groove can promote coating device and ceaselessly rotate.In fact, because the frictional resistance between wiper and the inside pipe wall is quite big, wiper is difficult to rotate in running, can't bottom liquid be carried to the top, can't be applied in the actual production.
U.S. Pat 6874193 proposes a kind of ejection-type corrosion inhibiter pipe cleaning device of filming.This device core component is mounted in the Venturi nozzle of head, and Venturi nozzle and pipe cleaning device afterbody are communicated with., the wiper backside gas dwindles suddenly when reaching Venturi nozzle through being installed in the intrinsic gas passage of pigging because of circulation area; Fluid obtains quickening; Produce negative pressure according to Bernoulli phenomenon, cause parital vacuum, thereby make the liquid that is deposited on the pipeline bottom carried the entering nozzle through the liquid suction tube; Carried secretly to the injection of tube wall top by air-flow, the preparatory film protection of corrosion inhibiter is carried out on pipeline top.
But above two kinds of coating devices in use all need to be used with another guiding wiper, so that between two wipers, form the corrosion inhibiter liquid plug of a sealing.But two wipers are coated with in the membrane process in pipeline; The speed of service difference can occur usually in the walking process; If the place ahead wiper speed is greater than the rear wiper; Liquid will occur and can not be full of two wipers institute enclosure space, have a strong impact on film quality thereby cause the top tube wall can not touch sustained release agent.In being coated with membrane process, the sustained release agent that is enclosed between two wipers also can get into the bypass line that links to each other with pipeline to be filmed, thereby and causes a large amount of wastes of corrosion inhibiter.
Summary of the invention
The object of the invention is intended to overcome the defective that coating device exists in the above-mentioned prior art; Proposition is based on the natural gas line corrosion inhibiter coating device of ultrasonic atomizatio principle; Need not to be used, adopt single coating device can corrosion inhibiter evenly be coated on the tube wall with other wiper.
The present invention is made up of atomising head and tubular body, the atomizing subchannel that is provided with the atomizing main channel in the atomising head and communicates with it, the atomizer of atomizing subchannel; The tubular body front and back end is respectively equipped with front shroud and back shroud; Front shroud has the centre bore that communicates with the main channel that atomizes, and back shroud top is provided with the bleed through hole, and tubular body inside is provided with dividing plate; The dividing plate top has passage; And tubular body is divided into two bins of fluid reservoir and premixer, and the fluid reservoir top is provided with the corrosion inhibiter filler, and the below is provided with the ultrasonic atomizatio chamber; Positioning disk and sealing cup are installed between the front shroud of atomising head and tubular body, and link to each other through bolt; Through bolt positioning disk and sealing cup are installed on the back shroud.
Be evenly equipped with the atomizing subchannel that communicates with the main channel that atomizes in the atomising head.
Indoor battery pack, ultrasonic generator, the piezoelectric ceramic piece of being equipped with of ultrasonic atomizatio, piezoelectric ceramic piece is installed in top, ultrasonic atomizatio chamber, and its outer rim is equipped with sealing ring; Be connected by lead between ultrasonic generator and piezoelectric ceramic piece and the battery pack.
The fluid reservoir top is provided with the corrosion inhibiter filler, on the corrosion inhibiter filler seal cover is installed.
The invention has the beneficial effects as follows: adopt single coating device can accomplish the pipeline corrosion inhibitor operation of filming; Spray corrosion inhibiter through a plurality of atomizers to pipe week; Overcome the shortcoming that traditional coating device scope of filming can not cover whole pipe week; Save the corrosion inhibiter consumption simultaneously, reduced the cost of filming.
