Background technology
Boiler is a kind of energy conversion, and the energy to boiler input has the chemical energy in fuel, electric energy, boiler output to have the steam of certain heat energy, high-temperature water or organic heat carrier.The original meaning of pot refers to the water container of heating on fire, and stove refers to the place of burning fuel, and boiler includes pot and stove two large divisions.The hot water produced in boiler or steam directly can provide required heat energy for commercial production and people's lives, it is possible to be converted to mechanical energy by Steam Power Equipment, or convert mechanical energy into electric energy by electromotor again.The boiler producing steam is referred to as steam boiler, is often simply called boiler, is used for thermal power station, boats and ships, locomotive and industrial and mining establishment.Boiler tail flue gas temperature is of a relatively high, in prior art, mostly the flue gas of boiler tail is directly discharge, and when directly discharging, then the heat energy in flue gas is wasted, although in prior art, the enterprise using boiler has reequiped some equipment the most voluntarily and flue gas has been carried out secondary utilization, but outfit of equipment is rougher, low to the utilization rate of flue gas, boiler tail flue gas if able to utilized, then can reach the effect of energy-saving and emission-reduction.
Utility model content
For solving the technical problem that in prior art, boiler tail flue gas utilization rate is low, this utility model provides a kind of energy-saving heat-exchange equipment that boiler tail flue gas utilization rate is greatly improved.
A kind of boiler energy-saving heat transmission equipment, it is characterised in that: including cylinder, two pieces of cards, ring flange, heat exchanger tubes, be respectively designed with shrouding before and after annular at cylinder two ends, the annular at front shrouding is connected with boiler tail flue gas pipe by ring flange；Annular passage at rear shrouding is connected with delivery pipe；On two pieces of cards, position in correspondence with each other has heat exchange pore, and what two cards were corresponding is fixed in cylinder, forms heat exchange chamber between two cards, and heat exchanger tube main body is positioned in heat exchange chamber, and two ends is respectively through card；Seal between card and cylinder, card and heat exchanger tube；Being designed with spilling water pipe above described heat exchange chamber, envisaged underneath has water inlet pipe.
This utility model boiler tail flue gas is led to ring flange enter energy-saving heat-exchange equipment front smoke chamber in, flue gas respectively enters in many heat exchanger tubes under the effect of the pressure, with the water heat exchange in heat exchange chamber after enter after smoke chamber, be connected with gas exhaust piping；While by flue gas, water is filled with in heat exchange chamber by the water inlet pipe of heat exchange cavity bottom, and the water surface slowly raises, and makes heat exchange more thorough.After water is full of chamber, the addition of water can be suspended, until after water temperature reaches requirement, then overflowing water pipe and open.Equipment of the present utility model is high to the remaining temperature utilization rate of boiler tail flue gas, damages simple and convenient, and cost of manufacture is low, has higher marketing and using value.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
A kind of boiler energy-saving heat transmission equipment, it is characterised in that: including cylinder 4, two pieces of cards 3, ring flange 1, heat exchanger tubes 6, be respectively designed with shrouding before and after annular at cylinder two ends, the annular at front shrouding 2 is connected with boiler tail flue gas pipe by ring flange 1；Annular passage at rear shrouding is connected with delivery pipe；On two pieces of cards 3, position in correspondence with each other has heat exchange pore, being fixed in cylinder of two card 3 correspondences, forms heat exchange chamber between two cards, and heat exchanger tube 6 main body is positioned in heat exchange chamber, and two ends is respectively through card 3；Seal between card 3 and cylinder 4, card 3 and heat exchanger tube 6；Being designed with spilling water pipe 7 above described heat exchange chamber, envisaged underneath has water inlet pipe a.
Smoke chamber after being formed between front smoke chamber, card and rear shrouding is formed between card and front shrouding, flue gas in smoke chamber can form the flue gas in condensed water, heat exchanger tube and also can form condensed water and flow in smoke chamber, for discharging in time condensed water and reducing condensed water to the erosion of equipment and damage, front and back, smoke chamber bottom is respectively designed with condensate drain water pipe 8.
Heat transmission equipment life-time service, the most inevitably has silt particle and aqueous alkali dirt.For being removed in time by above-mentioned impurity, described heat exchange cavity bottom is also devised with blow-off pipe 9.
In view of blow-off pipe 9 and water inlet pipe a are respectively positioned on cylinder body bottom, separately designing two groups and support seats 10 below described cylinder, supporting seat 10 bottom is square rack, upper surface be with cylinder 4 bottom the arcwall face that matches.Concrete structure sees Fig. 6, Fig. 7.
