Description
Technical field
The utility model relates to a kind of heat exchange of heat pipe, particularly relates to a kind of coke oven flue waste gas recovery heat exchange of heat pipe.
Background technology
Coke-oven plant is in coking is produced, the waste heat waste gas produced after coke oven heating through main chimney flue by chimney directly to airborne release, the EGT of discharge can reach 250 DEG C to 290 DEG C, and flue gas is discharged in the air by chimney from pull out force, the serious waste energy and pollution plant environment.In order to reach the object of energy-saving and emission-reduction, we, by technological transformation, recycle, by its waste heat recovery the direct waste heat waste gas discharged to air, the waste heat reclaimed is produced steam also for production and the life of on-site by heat exchange of heat pipe, reaches energy-saving effect.
Containing a large amount of corrosive substances such as nitride, sulfide in the waste gas produced in high-temperature coking process, very easily corrode inwall and the heat pipe of heat exchanger; And containing more dust in waste gas, heat exchange of heat pipe inside after Long-Time Service has a large amount of dust and overstocks, thus affects heat transfer effect.
The Chinese patent of CN203615793U discloses a kind of detachable heat exchange of heat pipe, and detachable meeting affects the sealing of heat exchanger to a certain extent, thus affects heat transfer effect; And the corrosion of nitride, sulfide in waste gas in high-temperature coking process can not be resisted, dust deposit problem can not be solved.
Summary of the invention
The purpose of this utility model is to provide a kind of coke oven flue waste gas recovery heat exchange of heat pipe, coke oven stack gases waste heat is recycled, and the corrosion of nitride, sulfide in waste gas in high-temperature coking process can be resisted, effectively solve dust deposit problem simultaneously.
The utility model is achieved through the following technical solutions:
A kind of coke oven flue waste gas recovery heat exchange of heat pipe, comprise heat-exchanging water tank, dividing plate, heat pipe and smoke chamber, be heat-exchanging water tank above dividing plate, it is smoke chamber below dividing plate, heat-exchanging water tank is provided with cooling water inlet and steam (vapor) outlet, smoke chamber is provided with gas approach and exhanst gas outlet, many heat pipes make upper end be fixed in heat-exchanging water tank by dividing plate, lower end is fixed in smoke chamber, heat pipe and dividing plate are for being threaded, it is characterized in that: the both sides of smoke chamber are respectively equipped with a water inlet, bottom is provided with two delivery ports, the structure of smoke chamber housing ecto-entad is followed successively by stainless steel tube wall, rock wool blanket heat-insulation layer, glass flake coatings a and equadag coating a, the thickness of glass flake coatings a is 4-5mm, the thickness of equadag coating a is 1-3mm, heat pipe is provided with the heat transmission fin distributed in the shape of a spiral, the surface of heat pipe is provided with glass flake coatings b and equadag coating b from inside to outside successively, the thickness of glass flake coatings b is 1-2mm, the thickness of equadag coating b is 1-2mm.
Rock wool blanket heat-insulation layer on smoke chamber housing can strengthen heat insulation effect, prevents the flue gas heat in smoke chamber to be dispersed into the external world, and the heat of flue gas is fully used.Glass flake coatings and the such composite anti-corrosive structure of equadag coating can resist the corrosion of nitride, sulfide in coke oven flue waste gas, the utility model also defines the thickness of glass flake coatings and equadag coating on smoke chamber housing, can guarantee antiseptic effect while production control cost.The heat transmission fin be distributed in the shape of a spiral on heat pipe increases the contact area of waste gas, improves heat exchange efficiency.Heat pipe also uses glass flake coatings and the such composite anti-corrosive structure of equadag coating, its antiseptic effect is better than the heat pipe only adopting individual layer corrosion-inhibiting coating, but on heat pipe, the thickness of glass flake coatings and the thickness of equadag coating are all no more than 2mm, otherwise can affect heat transfer effect.Smoke chamber arranges water inlet and delivery port, and accessible running water rinses the dust overstock in smoke chamber, prevents heat exchanger from using rear heat transfer effect to decline for a long time.
During use, when the waste gas produced in high-temperature coking process is entered in smoke chamber by gas approach, position heat pipe in the inner starts heat absorption, the heat of flue gas is passed to the cold water in heat-exchanging water tank by heat pipe, and make it vaporize, institute's producing steam is exported by steam (vapor) outlet, is delivered to plant area for production and life, reaches the object of UTILIZATION OF VESIDUAL HEAT IN.When heat exchanger uses for a long time, when a large amount of dust of generation overstocks in smoke chamber, open the water inlet being positioned at smoke chamber both sides, access running water rinses, and the addle after flushing is discharged by the delivery port bottom smoke chamber.
Beneficial effect: the utility model has that heat exchange efficiency is high, corrosion-resistant, Energy harvesting fully, long-time use after heat transfer effect do not descend degradation advantage.
