Description

A kind of high duty heat transfer element for being suitable for gas and liquid heat-exchange
Technical field
The utility model belongs to heat exchange heat transfer element technical field more particularly to one kind is suitable for gas and liquid The high duty heat transfer element of heat exchange.
Background technology
Exhaust gas is the main carriers of general energy consumption equipment waste energy, such as boiler exhaust gas, gas electricity generator, biogas cigarette Mainly energy consumption is discharged by high-temperature waste flue gas or off-air for gas, forming machine, compressor air-discharging, dryer and kiln etc., Not only waste of energy but also environment had been polluted.Efficiency of waste gas waste heat recovery apparatus is exactly that will be arranged by the efficient heat-exchange apparatus specially designed Entrained heat is converted into utilizable heat in the flue gas or air put, to generate hot water or heat other liquid Body reduces the exhaust temperature of exhaust gas, is to improve energy utilization rate so as to fulfill energy-saving and emission-reduction purpose, reduces production cost, protection Environment.
At present, in each civilian and industrial circle, flue gas caused by the natural gas boiler that largely uses is emitted into greatly Gas, smoke evacuation will take away a large amount of of combustion of natural gas generation and do not coagulate overboard steam, i.e. water mist simultaneously, and pass through efficient plate heat transfer Element can not only condense the water vapour in smoke evacuation, while can recycle a large amount of sensible heat and amount of latent heat, be that energy conservation and environmental protection is double The parallel behave of weight.
And traditional flue gas waste heat recovery apparatus is fin tube type or shell and tube, heat transfer efficiency is low, payoff period is long, volume is huge Greatly, cigarette resistance is big, of high cost, and can not realize the local replacing after localized heat transfer face or welding position damage, when portion of heat transfer face When being damaged, can only integral replacing, of high cost or do local plugging processing, exchange capability of heat declines, and can not meet operating mode will It asks.
A Maxi company techniques team actually uses the improvement of experience by research and development for many years and combination for many years, for natural This very big potentiality market of gas boiler flue gas waste heat recovery develops the natural steam pot in the world with innovative significance The special through-type template of the special flue gas waste heat recoverer of stove, possesses multinomial technical patent in this field.High efficiency plate fume afterheat Recover product has the practical ripe application experience of 6 years, and product has accomplished high-efficiency compact, long lifespan, easy care, payoff period Short, amount of on-site installation simplifies, and working service is most easy.
In domestic heating and industrial manufacture process, a large amount of demands for needing gas and gas heat exchange, gas packet are had Include air, flue gas (such as natural gas flue gas, coal-fired flue-gas, gas from oil burning), such as boiler exhaust gas, gas electricity generator, biogas cigarette The discharge heat of gas, forming machine, dryer and our each kiln etc. can effectively be recycled by heat-exchange apparatus, as The medium of preheated air reaches the good result of energy saving and environmentally friendly double incomes.But caused by the physical property of gas itself, gas with The heat exchange performance of gas is often relatively low, and conventional or traditional heat-exchanging part and equipment occur that investment is big, it is big to take up an area volume, returns The series of problems such as yield is low, payoff period length, in actual items in use, cost performance is relatively low, the waste of generation is still serious.
Therefore, it is necessary to develop novel substituted type high efficient gas and liquid type heat exchange products, to realize heat exchange efficiency height, payoff period It is short, take up little area, the advantages such as long lifespan.There are following a few quasi-tradition heat exchange products in existing market:1st, traditional carbon steel base tube fin Tubular type:Efficiency is very low, bulky, and payoff period is long, can generate wall surface corrosion due to sulphur dew point corrosion after a certain period of use time Perforated phenomenon;Substantially it is already belonging to the product that is eliminated;2nd, traditional stainless steel base tube set aluminium wing formula:Efficiency is very low, bulky, returns The receipts phase is long, and the large area corrosion of aluminum fin-stock is generated due to aluminium is intolerant to dew point corrosion;Thus containing corruption in the condensed water of kind equipment discharge The impurity for lose the residue that comes off (drain is in micro- dirty shape), coming off containing corrosion, it is very high to recycle cost;Because efficiency is low, volume is huge Greatly, it is not belonging to potentiality product;3rd, the copper pipe set additional corrosion-inhibiting coating formula of copper fin:Bulky, efficiency is still very low, and cost is very Height, unique publicity point are that the thermal conductivity factor of copper is higher, but corrosion-inhibiting coating can generate negatively influencing to heat conductivility again, simultaneously for For the heat exchanger of forced-convection heat transfer, the most effective approach for improving heat exchange efficiency is the heat-transfer capability of enhanced heat transfer component, is carried The thermal conductivity factor of high material is smaller to the promotion contribution of the whole heat transfer efficiency in engineer application, and corrosion-inhibiting coating once has one A point comes off or scratches, that is, generates whole leakage, be proved the waste heat recovery not applied to for natural gas flue gas.4th, pricker Welding type heat exchanger:Because of copper-based not resistant to sulfur dew point corrosion unavoidable in copper base brazing technique, 2-3 Heating Season (Beijing Area) it reveals to corrode and scrap, it has been proved the waste heat recovery not applied to for natural gas flue gas.
Therefore, the prior art is defective, needs to improve.
