Technical field

The present invention relates to a kind of wall-hung boilers to premix heat exchanger entirely, and in particular to a kind of pre-heated burning coil condensation heat exchange Device belongs to full premixed condensed technical field of heat exchange.

Background technique

In gas fired-boiler application field, including gas-heating water heater and commercial gas boiler, country is in environmental protection policy Under driving, the efficiency grade of boiler increasingly requires to reach level-one efficiency (see GB20665-2015 " domestic gas instantaneous water heater With gas-heating water heater energy efficiency market and efficiency grade "), stack gas emissions especially CO(mean hours concentration limit value Lower than 2000ppm) and NOX(mean hours concentration limit value be lower than 30mg/M3) also have strict requirements (see GB25034- 2012 " gas-heating water heaters ", GB13271-2014 " emission standard of air pollutants for boilers ").

Meet these requirements, from the point of view of technology, it is important that the burner and heat exchanger of core want energy in boiler Enough reach this requirement.But domestic these technical equipment of shortage, the equipment for being able to satisfy requirement are substantially needed from Europe at present Import, and the equipment of import is in use, since domestic combustion gas quality and environment influence, tends not to reach ideal The situations such as effect causes maintenance difficult, heat exchange efficiency decline, and service life reduces.

Therefore domestic demands research and development break through this technical bottleneck, largely develop the various of suitable for China and are able to satisfy requirement The equipment that burner and heat exchange equipment or burner and heat exchanger combine.Up to the present, the country also has similar really The same type equipment in Europe appears on the market, but because technology is immature or different to the understanding of technology, there is impracticable, unstable The various defects such as fixed, unreasonable are unable to satisfy country to energy-saving and environment-friendly requirement.

Summary of the invention

The technical problem to be solved by the present invention is to overcome the above-mentioned deficiency of the prior art, a kind of performance is provided and is met and exceeded Country-level efficiency and standard limit of smog release can be easy maintenance, being capable of reliable and stable work and service life long pre-heated Burn coil condensation heat exchanger.

To solve the above problems, the invention adopts the following technical scheme: a kind of pre-heated burning coil condensation heat exchanger, packet Detachable main body is included, is disposed with using equipment itself waste heat according to the flow direction of gas to be combusted in detachable main body Gas is preheated and mixed pretreatment unit, convenient for gas burning burner and convenient for the collection hot charging of Absorption of Medium energy It sets.

Be that the present invention advanced optimizes above scheme below: the pretreatment unit includes for treating burning gases The first flow guiding unit preheated.

Advanced optimize: being provided between first flow guiding unit and burner further mixes fuel with air The second flow guiding unit closed.

Advanced optimize: first flow guiding unit includes for flowing the deflector being oriented to for gas to be combusted.

It advanced optimizes: being provided with sealing upper cover on the burner, covered in sealing and be provided with upper cover, sealing upper cover, The diversion cavity convenient for gas flowing is formed between upper cover, deflector.

It advanced optimizes: being provided with protrusion on the deflector.

Advanced optimize: the protrusion is pyramidal structure.

Advanced optimize: second flow guiding unit includes support base, is provided with blade and air inlet on support base.

Advanced optimize: covered in the sealing die casting have it is multiple convenient for the connection that upper cover is connect with other component will be sealed Part.

It advanced optimizes: being provided with bottom case on the heat collector, bottom case is connected with anti-down windshield plate, bottom case and down-draught-proof Baffle is formed using integrated die-casting.

By testing and actually using, the present invention has the advantages that with respect to traditional heat exchangers and advantage:

1. performance indexes meets GB25034-2010 " gas-heating water heater " standard；

2, condensed water etching problem is effectively solved；

3, extremely low nitrogen oxides (being lower than 30mg/M3) and CO discharge (being lower than 300ppm)；

4, coil pipe can be dismantled to be cleaned or replaced, after-sales service is facilitated to maintain；

5, effective burning cavity cooling；

6, air fuel gas reasonably flows mixing；

7, small in size, versatility is high, compatible more power types；

8, single pass coil pipe compares the coil pipe of multichannel, and no-welding-spot avoids corrosion due to welding, avoids moisture seal and let out Leakage；

9, the heat exchangers such as straight tube are compared, this heat exchanger heat exchange area is bigger under same volume, and power is higher, preferably saves wall hanging The space of furnace.

Present invention will be further explained below with reference to the attached drawings and examples.
