Description
Technical field
The utility model patent relates to the cooling of quenching oil and reclaims the heat pipe heat exchanging equipment of its waste heat.Be specially adapted to the cooling in the industrial circles such as metal heat treatmet, metallurgy, forging and reclaim the heat pipe heat exchanging equipment of its waste heat.
Background technology
In the industrial circles such as metal heat treatmet, metallurgy, forging, for the mechanical property that improves metallic substance is carried out quench treatment, when metal is carried out quench treatment, metal works need to be heated to a certain specified temp and keep for some time, immediately fast cooling in the dip quench medium is to obtain specific metallographic structure.
Quenching oil is exactly most important a kind of in the middle of the quenchant, quenching oil is a kind of process oil, the novel quenching oil that uses at present mainly contains three kinds of fast quench oil, bright quenc hing oil and vacuum quenching oils, quenching oil needs it is constantly cooled off in application process, and remains in the temperature range of regulation.
In the structure of at present traditional quenching oil cooling system, the turning oil pipeline of quenching oil is by plate-type heat exchanger 8(oil-water) carry out heat exchange, finish the cooling of quenching oil.This cooling system has following shortcoming:
(1) by plate-type heat exchanger oil-water is carried out heat exchange, the heat that quenching oil the discharges water that is cooled absorbs, and can not be used, and just is discharged in the surrounding environment, forms thermal pollution source, waste heat energy.
(2) adopt glass fibre reinforced plastics cooling tower as heat abstractor, cooling performance is not good, makes quenching technology be difficult to realize.In the northern area of China, the water projection of glass fibre reinforced plastics cooling tower can cause freezed in winter, and equipment can't be worked, and the system that affects normally moves.
(3) adopt the cooling basin as heat abstractor, spray or naturally cooling.So no matter the pond is on the ground or underground, all be difficult to avoid water coolant to be occurred by the problem of contamination by dust, and floor space is large, oxygen can constantly enter in the system simultaneously, can aggravate the corrosion of the facilities such as pipeline, water tank, even some solid matters can threaten the circulation of the cooling-water duct of equipment, and operation causes potential safety hazard to equipment.
(4) the evaporation water loss is large, because the evaporation of moisture all can't be avoided in no matter cooling tower or cooling basin, in fact they rely on evaporation to obtain to cool off to a great extent, this kind mode, the water resourcess of a large amount of preciousnesses of waste.
(5) adopt plate-type oil-water-to-water heat exchanger, after the operation certain hour, can produce the faults such as fouling or runner obstruction, need regular maintenance, otherwise can affect significantly the heat transfer effect of equipment.
(6) adopt plate-type oil-water-to-water heat exchanger, when the turning oil pipeline breaks, oil mixing with water occurs easily, the blending of cold fluid and hot fluid, danger that can be explosion caused.
Some that exist in the existing patent are to the oil cooled equipment that quenches, such as disclosed relevant quenching oil cooling apparatus among Chinese patent application CN200710132922.8, the CN200920019514.6, this two kind equipment can be used for the cooling work of quenching oil, yet this two kind equipment structurally quenching oil cooling system with traditional is similar, this two kind equipment is when oil pipe breaks, oil mixing with water also occurs easily, the blending of cold fluid and hot fluid, danger, safety coefficient that can be explosion caused be low.
Because the existence of the problems referred to above, the inventor carries out research and analysis to the quenching oil properties, traditional quenching oil cooling system and existing quenching oil cooling technology are studied, so as to produce can effectively utilize heat energy, not pollute water coolant, cooling efficiency is high, save cooling water resources, can also recycle, simple in structure, heat pipe heat exchanging equipment that a kind of quenching oil that safety coefficient is high cools off and reclaim its waste heat.
