Description
Technical field
The utility model relates to high-efficiency tobacco pipe type exhaust heat boiler, and it is a kind of employing multiple thread smoke pipe, and High Efficiency Thermal reclaims, and corrosion resistant waste heat boiler, belong to waste heat boiler technical field.
Background technology
Containing a large amount of heat energy in the tail flue gas of kiln, before fume emission, all to carry out recuperation of heat, avoid industrial heat energy to waste.A kind of heat recovery boiler that fume tube type waste heat boiler is comparatively conventional.The seamless steel pipe that the many employings of smoke pipe of traditional fume tube type waste heat boiler are smooth, heat exchanger effectiveness is not high, and the etchant gas that flue gas contains, strong to the corrosivity of smoke pipe, cause boiler easily to tie ash blocking, smoke pipe seriously corroded, the waste heat boiler life-span is shorter.
Summary of the invention
In order to solve above-mentioned Problems existing, the utility model discloses a kind of high-efficiency tobacco pipe type exhaust heat boiler, this waste heat boiler heat recovery efficiency is high, good corrosion resistance, long service life.
High-efficiency tobacco pipe type exhaust heat boiler, comprise body of heater, one end of body of heater is gas approach, the other end is exhanst gas outlet, the below of described body of heater is provided with the support fixed on the ground, the top of described body of heater is provided with steam (vapor) outlet, some smoke pipes have been horizontally disposed with in body of heater, the tube wall screw thread of described smoke pipe bends, body of heater two ends are respectively arranged with fixed head, fixed head is provided with several fixing holes, the two ends of smoke pipe are fixed through fixing hole and fixed head, the outside of fixed head is respectively arranged with several gates, gateage shelters from corresponding gas approach and exhanst gas outlet.
Described smoke pipe is the multiple thread pipe that one or more screw thread parallel is each other bent to form.
Described fixed head surface is provided with ceramic layer.
Described gate is provided with electric operator.
The fixed head surface of described gate between adjacent smoke pipe.
Described smoke pipe is that corrosion resistant ND is without seam steel pipe.
The utility model, when flue gas fluid passes through in smoke pipe, be subject to screw thread curved guide, near smoke pipe inwall, axially-movable, flue gas is subject to the bending concavo-convex change of smoke pipe screw thread, flue gas fluid produces periodic disturbance, makes flue gas produce strong turbulent flow, accelerates the tube wall of smoke pipe and the heat transmission of fluid, screw thread bends the heat exchange area increasing smoke pipe, improves heat recovery efficiency.
Ceramic layer, to there being very strong corrosion resistance, effectively preventing from being corroded by the pernicious gas in flue gas, increases the service life, and meanwhile, using corrosion resistant ND without seam steel pipe as smoke pipe, is also to prevent smoke pipe to be corroded.
The utility model, by controlling to open gate, ventilating, blowing ash to smoke pipe, reaching clean smoke pipe in gate, reduces the effect of smoke pipe knot ash.Gate effectively controls the ventilating opening area ventilated, and by reducing ventilating opening area, can improve the speed of ventilation, improves the intensity of blowing ash.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.Following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
Fig. 1 is structural representation of the present utility model, arrow in figure represents the flow direction of flue gas, as seen from the figure, the utility model, body of heater 1 by support 4 fixed support on the ground, is provided with the smoke pipe 6 that several are parallel to each other in body of heater 1, the two ends of smoke pipe 6 are provided with fixed head 7, smoke pipe 6 is fixed through the fixing hole 8 on fixed head 7 and fixed head 7, and body of heater 1 one end is gas approach 2, and the other end is exhanst gas outlet 3.During use, the flue gas from boiler enters the utility model from gas approach 2, and the flue gas plate 7 that is fixed blocks, concentrate and pass through from smoke pipe 6, be full of outside smoke pipe 6 by the medium heated, flue gas is exchanged by smoke pipe 6 and the medium heat outside smoke pipe 6, absorbs the heat in flue gas.
The top of body of heater 1 is provided with several steam (vapor) outlets 5, and smoke pipe 6 surrounding is full of by the medium heated, and after the heat energy of the flue gas in Absorption of Medium smoke pipe 6, the heat of self increases, and medium evaporates, and is regulated the stable air pressure in body of heater 1 by steam (vapor) outlet 5.
Fixed head 7 surface is provided with ceramic layer 10, can effectively prevent the harmful substance in flue gas from eroding to fixed head 7.
The surface of fixed head 7 is provided with gate 9, can regulate by opening gate 9 flow velocity ventilated in smoke pipe 6.Knot ash in smoke pipe 6 can blow and brush off by coutroi velocity, easy to use, reduces the knot ash in smoke pipe 6.
Gate 9 is provided with electric operator 11, by the switch of electronic execution machine 11 regulable control gate 9, easy to adjust.
Fig. 2 is the structural representation of smoke pipe 6, and as seen from the figure, the tube wall screw thread of smoke pipe 6 bends, and smoke pipe 6 is multiple thread pipes that one or more screw thread parallel is each other bent to form.Multiple screw thread warp architecture parallel each other, the flue gas fluid in smoke pipe 6 can be allowed to produce strong rotary motion, and flue gas fluid produces strong souring to smoke pipe 6 inwall; The male and fomale(M&F) self that screw thread is bending has and has thermal compensation ability, and the area expanded with heat and contract with cold is complementary, and the resistance that flue gas fluid is subject to is little, and flow velocity is fast, and smoke pipe inwall is not easy knot ash.Meanwhile, the smoke pipe 6 that the utility model uses selects corrosion resistant ND without seam steel pipe, and corrosion resistant ND effectively prevents smoke pipe 6 from being corroded by the pernicious gas in flue gas without seam steel pipe, extends the service life of smoke pipe 6.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned technological means, also comprises the technical scheme be made up of above technical characteristic.
