Abstract
The utility model relates to a washing device, particularly a dry ice washing device which is used for an organic vehicle heating furnace by making use of a principle of using the dry ice to decontaminate. The utility model is provided with a dry ice insulation can, a device for supplying compressed air, a dry ice spotter and a spray lance, wherein, the dry ice insulation can which is used for storing the dry ice is used for storing dry ice granules; an output pipe of compressed air of the device for supplying compressed air is connected with an inlet of compressed air of the dry ice spotter; the spray lance is connected with an outlet of the dry ice granules of the dry ice spotter. The dry ice washing uses the dry ice granules to impact a surface which is needed to be washed at high speed through the compressed air. Because of an instantaneous loss of bond energy and the quick transmission of thermal energy which are caused by the impact of the dry ice, carbon dioxide solid is changed into gas instantaneously, and the surface of dirt is cooled, embrittled and is separated from the surface which is needed to be washed. Compared with the conventional washing methods, such as high pressure water, sandblasting, etc., the dry ice washing belongs to a dirt washing method under the action of shearing force, and the utility model does not damage the surface of a washed object and equipment. After washing, the dry ice is gasified instantaneously and no secondary waste is generated. The spray lance of the utility model can be conveniently changed, the utility model is suitable for different furnace shapes, and the utility model can make use of parking time to wash without influencing production.
Description
(1) technical field
The utility model relates to a kind of cleaning device, especially utilizes the dry ice decontamination principle to be used for the Dry ice cleaning device of organic carrier heating furnace.
(2) background technology
Many equipment of various industries, for example mould, electronic motor, boats and ships, vehicle, aircraft, generating, petrochemical industry, printing etc. all need the scrubbing cleaning equipment.For example as the organic carrier heating furnace at manufacturing enterprise energy supply center, along with the prolongation of running time, the thermal efficiency of heating furnace descends, and crude oil consumption increases.Its key factor is that the knot carbon fouling covers tube wall in the stove, influences convection heat transfer' heat-transfer by convection, causes effluent gas temperature higher, causes thermal efficiency of heating furnace to descend.Because stove inner coil pipe structure is special, internal and external disk pipe clamp lamellar spacing is very little, adopts conventional methods such as the water under high pressure cleaning and the cleaning of sandblasting to be difficult to clean its knot carbon fouling.
(3) summary of the invention
The purpose of this utility model is to provide a kind of Dry ice cleaning device that is used for organic carrier heating furnace.
The utility model is provided with dry ice incubator, compressed air feedway, dry ice decontamination machine and spray gun.The dry ice incubator of depositing dry ice is used to deposit dry ice pellet; The compressed air efferent duct of compressed air feedway connects the compressed air inlet of dry ice decontamination machine; Spray gun connects the dry ice pellet outlet of dry ice decontamination machine.
Dry ice cleaning is to use the surface of dry ice medium (particle) by the required cleaning of compressed air high-speed impact, because the instantaneous loss in conjunction with energy of dry ice bump reaches thermal energy transfer fast, carbon dioxide solid moment becomes gas, makes the embrittlement of dirt surface cooling and breaks away from the surface.Compare with water under high pressure, conventional cleaning method such as sandblast, Dry ice cleaning belongs to the dirt cleaning method under the shearing force effect, does not damage to be cleaned the thing surface, does not damage equipment.In addition, the moment gasification does not produce secondary slugs after the Dry ice cleaning.Be convenient to simultaneously change various spray gun, be suitable for the demand of different stove shapes, and can utilize the chance of parking to clean, do not influence production.
(4) description of drawings
Fig. 1 is a composition frame chart of the present utility model.
(5) specific embodiment
As shown in Figure 1, the utility model is made up of dry ice incubator 1, air compressor 2, dry ice decontamination machine 3 and spray gun 4.Dry ice incubator 1 is used to deposit dry ice pellet, and the compressed air efferent duct of air compressor 2 connects the compressed air inlet of dry ice decontamination machine 3; Spray gun 4 connects the dry ice pellet outlet of dry ice decontamination machine 3.The dry ice decontamination machine can adopt U.S. COLD JET company product, for example RDS-250CUB, RDS-500CUB, RDS-1000D type product.
During use, the device that is cleaned is stopped, heat, conduction oil are discharged in the boiler tube; Pour the proper amount of dry ice pellets in the dry ice incubator into the dry ice decontamination machine, start air compressor; With corresponding spray gun to boiler tube jet surface dry ice pellet; Remove ashes, dirt that the boiler tube surface comes off.Usually, can control pneumatics flow 〉=6kg.Prove that by the field experiment of heating agent stove Dry ice cleaning is to remove the best-of-breed technology scheme of heating furnace accretion carbon fouling, clean the back thermal efficiency and flue gas oxygen content and obviously improve that the gentle exhaust gas temperature of cigarette obviously reduces before the air preheater, fuel-economizing is obvious, remarkable in economical benefits.
