Description
Technical field
The utility model relates to a kind of waste heat boiler.
Background technology
At present, industries such as oil, chemical industry, iron and steel, electric power produce steam and hot water with the high-temperature flue gas that produces in the technical process through heat exchange for energy-conservation, are used for producing and life.This just need achieve the goal through this equipment of waste heat boiler, consumes to save the energy, to reduce.Its structure of the waste heat boiler that is widely used now mainly is: steam-generating bank and support their steelframe, and steam-generating bank links to each other with drum (drum) through outside connecting leg, when less and temperature is higher when flue gas flow; In order to reach certain heat transfer efficiency, the flue gas flow area is less, but the heat-transfer surface of the higher needs of temperature is bigger again; The vertical layout of equipment, equipment is not only thin but also high, during the horizontal layout of equipment; Not only thin but also long; So not only took up room but also improved equipment cost, caused unnecessary economic loss, also do not meet energy-saving and cost-reducing requirement.
Summary of the invention
The purpose of the utility model is to provide that a kind of equipment manufacturing cost is low, many backhauls of multiaspect corner tube type waste heat boiler little, compact conformation takes up room.The concrete scheme of the utility model is following: a kind of many backhauls of multiaspect corner tube type waste heat boiler; It is characterized in that: it is distributed in four vertical and have certain intensity pipes of four jiaos in this boiler, and two is tedge, and two is down-comer; Their upper end is communicated with drum and supports drum; Their lower end all links to each other with the basis, is provided with the evaporimeter tube bank below the drum, and it be upper and lower many rows side by side; Each is connected the two ends of this same row's evaporimeter tube bank with a collecting box pipe; The two ends of this two collecting box pipe are connected with tedge and down-comer respectively again, in above-mentioned two tedges and down-comer, are provided with plugging mechanism, its be positioned at the bottom collection case of evaporimeter tube bank below; On the side plate of smoke box, be respectively equipped with flue gas import and export pipe, in above-mentioned smoke box, be provided with the deflection plates that the evaporimeter tube bank is passed and three are held the limit all to link to each other with smoke box.Evaporimeter tube bank and inclined certain angle.Evaporimeter tube bank peripheral hardware has helical fin or fin.On the sealing plate of smoke box bottom, establish ash discharging hole.On the smoke box side plate, be provided with the soot blower interface.On the smoke box side plate, be provided with inspection manhole.The utility model mainly includes: drum, tedge and down-comer, collection case, evaporimeter tube bank, smoke box, smoke entrance pipe, baffling dividing plate and ash releasing tube.Wherein, be distributed in four of four jiaos in this boiler vertically and the pipes with certain intensity, their upper end is communicated with drum and supports drum.In these four pipes, two is tedge, and two is down-comer, and they and drum constitute circulation line.The lower end of above-mentioned four pipes all links to each other with the basis, as the pillar of this waste heat boiler.Be provided with the evaporimeter tube bank below the drum; Preferably evaporimeter tube bank peripheral hardware has helical fin or fin, and it is many rows arranged side by side up and down, preferably this evaporimeter tube bank and inclined certain angle; Each is connected the two ends of above-mentioned same row's evaporimeter tube bank with a collecting box pipe; The two ends of this two collecting box pipe are connected with tedge and down-comer respectively again, because the evaporimeter tube bank has many rows, so collecting box pipe also is arranged side by side up and down many.In above-mentioned two tedges and down-comer, be provided with plugging mechanism, its be positioned at the bottom collection case of evaporimeter tube bank below.The outside of restraining, collecting case and part tedge and down-comer at above-mentioned evaporimeter is provided with encloses side plate within it with them, and top and bottom is provided with sealing plate, and they constitute smoke box, on the side plate of smoke box, are respectively equipped with flue gas import and export pipe.Best, be provided with inspection manhole and soot blower interface on ash discharging hole, the side plate establishing on the sealing plate of bottom, be beneficial to dust stratification and remove, guarantee the equipment reliability of operation.In above-mentioned smoke box, be provided with several deflection plates that the evaporimeter tube bank is passed and three are held the limit all to link to each other with smoke box; These deflection plates constitute a plurality of little smoke-boxes of connecting with the smoke-box housing; So both guaranteed that enough heat exchange areas reclaimed the waste heat in the flue gas, and improved flue gas flow rate again and then improve heat exchange efficiency.
The utility model compared with prior art has following advantage:
1, the utility model four angle posts not only are rising, down-comer but also the effect of playing the fastening own wt, need not make steelframe in addition.
2, need not connect outer connecting leg road in addition between the utility model drum and the evaporimeter, reduce the site operation amount, provide cost savings.
3, the utility model compact conformation, take up room little, bring big flexibility for technological design, manufacturing and on-the-spot the installation, be suitable for the restricted occasion of installing space.
4, the utility model is restrained horizontal layout and is left the soot blower interface, and heat-transfer surface is difficult for dust stratification.
