Abstract
The utility model discloses a kind of gas normal-pressure hot-water boiler flue gas condenser, including header, wherein, exhanst gas outlet is provided with above the header, header lower section is provided with gas approach and condensate drain outlet, described header the same side is provided with water inlet, delivery port and air door, flue gas condensing absorption tube is set inside the header, and the flue gas condensing absorption tube both ends are connected with water inlet, delivery port respectively.The utility model is using corrugated tube as flue gas condensing absorption tube, Z-shaped structure inside corrugated tube, reduce the setting of heat exchange pipe expansion joint and the processing of dirt, to reclaim the fume afterheat of gas fired-boiler, therefore, working service is extremely convenient for the efficiency of combustion of raising boiler.
Description
Technical field
A kind of combustion gas flue gas condenser is the utility model is related to, particularly a kind of gas normal-pressure hot-water boiler flue gas condensing
Device, it is the energy-conserving product related to boiler, the flue-gas temperature suitable for reducing gas fired-boiler, improves the thermal efficiency, while reclaim cigarette
The gas fired-boiler heat transmission equipment of gas waste heat.
Background technology
In conventional boiler, for fuel after boiler combustion, exhaust gas temperature is of a relatively high, and the water vapour in flue gas is still in gas
State, substantial amounts of heat can be taken away in all kinds of fossil fuels, the hydrogen content highest of natural gas, the mass percent of hydrogen is about 20%
To 25%, therefore, substantial amounts of water vapour is contained in smoke evacuation, according to measuring and calculating, burn what steam caused by 1 square metre of natural gas to be taken away
Heat paper is 4000KJ, about more than the 10% of its high calorific power.
Smoke condensing waste heat recovering device, using the relatively low water of temperature or air cooled flue gas, flue-gas temperature reduction is realized,
Water vapour condenses in heat-transfer surface region, flue gas, while realizes obvious heat of smoke release and water recovery latent heat treatment, and changes
Water or air in hot device absorb heat and are heated, and realize energy recovery, improve boiler thermal output.
Due to flue gas condensing, thus in condenser flue gas condensing absorption tube easily occur intercrystalline corrosion, reduce heat exchange efficiency,
The problems such as service life is short.
The content of the invention
Problem to be solved in the utility model is to provide a kind of gas normal-pressure hot-water boiler flue gas condenser, to solve cigarette
Gas condenser sends out the problems such as intercrystalline corrosion easily occurs for flue gas condensing absorption tube, service life is short, and to improve the burning of boiler effect
Rate.
Gas normal-pressure hot-water boiler flue gas condenser disclosed herein, including header 1, wherein, the top of header 1 is set
There are exhanst gas outlet 3, header lower section to be provided with gas approach 2 and condensate drain outlet 7, described header the same side is provided with water inlet
4th, delivery port 5 and air door 6, the inside of header 1 set flue gas condensing absorption tube 8, the both ends of flue gas condensing absorption tube 8 difference
It is connected with water inlet 4, delivery port 5；
In order to solve the problems such as intercrystalline corrosion occurs for flue gas condenser, service life is short, the flue gas condensing absorption tube 8 is
Corrugated tube made of the rotation of fin forest tract.
In order to improve heat exchange efficiency, further improve is, the corrugated tube is made of 304L stainless steels
Inside is the structure of Z-shaped.
Compared with prior art, the utility model uses corrugated tube as flue gas condensing absorption tube, corrugated tube
Internal Z-shaped structure, so after flue gas, which enters, is equipped with Z-shaped structural corrugations heat exchanger tube, cooling separates out impurity can and hindered
Gear, discharge or heat up along Z-shaped structure and discharge, you can voluntarily processing recovers, and will not be stacked on corrugated tube, meanwhile, by
In the special shape of bellows, reduce the setting of heat exchange pipe expansion joint and the processing of dirt, to reclaim the flue gas of gas fired-boiler
Waste heat, improve the efficiency of combustion of boiler therefore, working service is extremely convenient.
Brief description of the drawings
Fig. 1 the utility model flue gas condenser structural representations；
Fig. 2 the utility model corrugated tube structural representations；
Fig. 3 the utility model corrugated tube internal structure schematic diagrams.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Fig. 1, Fig. 2 combination Fig. 3 can be seen that the utility model gas normal-pressure hot-water boiler flue gas condenser, including header
1, wherein, the top of header 1 is provided with exhanst gas outlet 3, header lower section is provided with gas approach 2 and condensate drain outlet 7, institute
State header the same side and be provided with water inlet 4, delivery port 5 and air door 6, the inside of header 1 sets flue gas condensing absorption tube 8, institute
The both ends of flue gas condensing absorption tube 8 are stated respectively with water inlet 4, delivery port 5 to be connected；The flue gas condensing absorption tube 8 is fin forest tract
Corrugated tube made of rotation；The corrugated tube is the structure that inside is Z-shaped made of 304L stainless steels.
The utility model using corrugated tube be used as flue gas condensing absorption tube, corrugated tube inside Z-shaped structure, this
After flue gas enters and is equipped with Z-shaped structural corrugations heat exchanger tube, cooling separates out impurity can and is blocked sample, is arranged along Z-shaped structure
Go out or the discharge that heats up, you can voluntarily processing recovers, and will not be stacked on corrugated tube, simultaneously as the special form of bellows
Shape, reduce the setting of heat exchange pipe expansion joint and the processing of dirt, to reclaim the fume afterheat of gas fired-boiler, improve the combustion of boiler
Burn efficiency therefore, working service is extremely convenient.
