Description

Bromomethane vaporizer

Technical field

The present invention relates to a kind of vaporizer of fumigation medicament Celfume; Particularly a kind ofly the stifling problems such as using Celfume and vaporization effect difference of handling can be overcome under the low temperature environment, the vaporizer that reaches the fumigation medicament Celfume of an ideal temperature when making Celfume export spray gun in the dispenser process can be applied in.

Background technology

At present, Celfume is wherein a kind of medicament commonly used in the stifling processing in China port, has the strong characteristics of permeability, also is the stifling appointment medication of cargoes imported and exported in the world.Celfume generally is processed into bottled liquefied gas and supplies each port to use.In the dispenser process, need to rely on the pressure in the steel cylinder, a certain amount of liquid bromine methane is exported from pipeline opening, and through the dispenser skirt with the Celfume of liquid state be delivered to stifling space and rapidly vaporization be full of stifling space, realize the stifling purpose of handling.

In stifling processing procedure, when the temperature of liquid bromine methane was lower than 16 ℃, the vaporization rate behind its output spray gun obviously reduced, and temperature is low more, and it is poor more to vaporize.Often cause the operative liquid Celfume not vaporize, otherwise form watery.Owing to can not vaporize, medicament can not reach needs stifling place, thereby has a strong impact on the stifling effect of handling.

The Chinese patent communique once disclosed utility model patent " the quantitative vaporizer of Celfume in winter " on April 25th, 2007, it has the body of a band handle, and body is provided with the spray gun of a transparency window and a band tilt port.Inlet tube on the handle is connected with sealed tube in the rod body, is provided with the spray gun cone valve in the sealed tube, is provided with the spring of control bullet Push And Release in the cone valve; Pneumatic indicator is established in side at sealed tube, establishes spring in the pneumatic indicator and shows the top button, and the spring below is established reverse taper and is used to show the gas pressure in the sealed tube; The tube wall place of the below of sealed tube is provided with the internal heating type electrothermal tube.This scheme is safety inadequately, because its heat-generating pipe design at nozzle location, only adopts electrothermal tube directly Celfume to be heated in the Celfume exit; So just power line must be arranged, quite inconvenient during use, and do not have heat insulation function; Waste energy, the temperature of heating can't accurately be controlled, in addition for making Celfume meet the requirements of temperature; Preheating time is long, and the power requirement of electrothermal tube is bigger, and efficient is low.

Summary of the invention

The object of the invention, just provide a kind of simple in structure, use very convenient, the Bromomethane vaporizer that fast, the temperature retention time length of Celfume vaporization, energy savings, the temperature of heating can accurately be controlled under low temperature environment.

For realizing the foregoing invention purpose; Bromomethane vaporizer of the present invention; It is characterized in that: include lid container, electrothermal tube is housed in the container and fills conduction oil, described container and lid all attach heat-insulation layer outward; Be soaked with the metal coil pipe as liquefaction medicament passage in the described conduction oil, its import and export is external to Celfume medicine bottle and spray gun respectively.

On the basis of the above, the present invention also can further improve and have various remodeling.

Described heat-insulation layer is with metal-coating outward.

Described coil pipe is the metal coil pipe, and its posterior segment caliber is greater than the leading portion caliber.

Described metal coil pipe front and rear sections is inside and outside coil spring shape.

Have the side mouth on the bucket wall of described container bottom side cover is housed, power control circuit is housed on it, the electrothermal tube that can stretch into conduction oil is equipped with in the side cover inboard.

Described electrothermal tube is through the power supply of AC and DC double-purpose electric source control circuit.

On the described power control circuit temperature controller is housed, its temperature probe stretches in the conduction oil.

Described coil pipe is fixed on the container cover, and it fixes and pass container cover into and out of oral area.

Also be provided with thermometer on the described container cover, it passes bung and can stretch in the conduction oil.

Described container is stamped inside and outside the air-vent connection container.

Operation principle of the present invention is to adopt the thermal energy exchange principle; With the metal coil pipe as liquefaction medicament passage and heat exchanger; With the conduction oil is heat-conducting medium, adopts electrothermal tube heating conduction oil, flows through in the metal coil pipe of liquefaction medicament in being dipped in conduction oil; Through metal pipe-wall generation heat exchange; Thereby make to be lower than liquefaction medicament temperature after absorbing heat energy that uniform temperature can not vaporize or vaporize slower and to raise gradually and reach the ideal temperature value, the liquefaction medicament produces certain pressure because temperature raises during through the metal coil pipe, and has the partial liquefaction medicament vaporization to become gas and in the dispenser pipeline, form gas-liquid mixture; Increase the condensation rate of liquefaction medicament when the dispenser spray gun sprays, thereby improve vaporization effect; Vaporizer adopts Electromechanical Design, and heat exchange section adopts asbestos parcel heat-insulation layer, and the dual-purpose electric apparatus control apparatus of friendship (directly) stream is equipped with in the side; Heat-insulating property is good, and energy savings is fit to open-air the use; Compact conformation, the automatic control degree is high, operates simple and easy; Can satisfy stifling treatment requirement, be specially adapted to the stifling processing of cargoes imported and exported.

In use; The Celfume of liquid is by the metal coil pipe import input of fixing and pass container cover; The conduction oil of electrothermal tube heating simultaneously; Liquid bromine methane in the metal coil pipe raises through the pipeline endothermic temperature, satisfies the aerosolization requirement in the time of can guaranteeing the Celfume arrival metal coil pipe outlet in the pipeline through the heating of regulating electrothermal tube.

Beneficial effect: the present invention is simple in structure, use is very convenient; The vaporization of heating Celfume is fast when under low temperature environment, using; Reach a desirable vapourizing temperature when making Celfume output spray gun; Temperature retention time is long, and heating once can be accomplished the dispenser (being equivalent to dispenser 25kg one time) of nearly 15 TEU (Twenty-foot Equivalent Unit)s; The heat-conducting medium thermal efficiency that adopts is high, conduct heat evenly, energy savings and can accurately control temperature, in rational dispenser process, but in the set point of temperature scope long period use.And adopt two kinds of heat forms of AC and DC electricity, can adapt to different working environments.
