Description
Technical field
The present invention relates to a kind of heat exchanger degreasing technique field, more particularly to a kind of heat exchanger waste-oil scavenger.
Background technology
Existing heat exchanger (e.g., the condenser on air-conditioning equipment, evaporator) has used volatilization in process of manufacture
Oil., it is necessary to oil removing, removing type drying be carried out, to prevent from occurring ant nest corrosion on heat exchanger before the welding of heat exchanging device.
The prior art mainly carries out oil removing, drying using opening chain type drying oven as waste-oil scavenger heat exchanging device.Its
In, opening chain type drying oven mainly uses gas furnace heat exchanging device integrally direct heating, drying；And waved what heat exchanger produced
Hair oil is expelled directly out.In addition, leakage caused by Welding of Heat-exchanger exception in order to prevent, general use fills compression air analysis heat exchange
Device whether there is big leakage (detecting leakage), after No leakage, then irrigates helium into heat exchanger copper pipe, is set using special stop leakage in the roof
It is standby to examine heat exchanger to whether there is minute leakage.
But the inventors found that at least deposited as heat exchanger waste-oil scavenger using opening chain type drying oven
In following technical problem：
(1) since drying oven is Open architecture, when integrally being heated using combustion gas heat exchanging device, what combustion gas produced
Heat can be distributed largely；First slip of volatile oil is a little 170 DEG C or so in heat exchanger, conventional drying need to be heated to 160~180 DEG C or
Higher, energy consumption is larger, and the enthalpy that the tail gas of discharge is taken away is often relatively more, and the thermal efficiency is low, and production cost is high.Also, drying course
Middle volatile oil is unable to centralized recovery processing, and evaporateing into workshop causes that air quality in workshop is poor, and working environment is poor.
(2) opening chain type drying oven on the one hand causes energy consumption sharp using direct-fired heating (that is, using combustion gas stove heat)
It is relatively low with rate, production efficiency；On the other hand so that opening chain type drying oven takes up a large area that (having a surplus wide 4 meters for long 10 meters has
It is remaining).
(3) there are serious environmental pollution：Drying oven can produce heavier oil smoke in the degreasing drying course of heat exchanging device
Taste.What this oil smoke was mainly produced by following two aspects：On the one hand, the gas drier used is direct-fired, natural gas, liquefaction
Poisonous, the flavored gases such as sulfur dioxide that the impurity combustion of sulfur that contains in gas produces, hydrogen sulfide；On the other hand, heat exchanger
Volatile oil volatile oil in the poisonous of generation, pernicious gas and pyroprocess are cracked in drying pyroprocess VOC that quickly volatilizees (has
Machine thing) discharge generation, air pollution directly can be produced to air discharge, be unfavorable for environmental protection.In addition, increase on drying oven
The early investment of VOC exhaust gas processing devices, the cost of later stage production run are higher.
(4) dries quantity is poor：The temperature fluctuation range of combustion gas drying oven is big, and the oil inside heat exchanging device copper pipe can not have
Effect control.When drying temperature is excessive, oxidation stain easily occurs for copper pipe, or aberration occurs in row's copper pipe up and down, influence appearance and
Heat exchange property.When drying temperature is too low, the oil being easy to cause in copper pipe can not be dried effectively, and be corroded with ant nest is produced
Hidden danger.
In addition, the above-mentioned prior art, which need to separate, carries out two oil removing drying, leak detection processes so that the production efficiency of heat exchanger
It is low.
