Abstract

The utility model provides a corner-tube waste heat boiler, mainly comprising four vertical tubes distributed at the four corners of the boiler, wherein the upper ends of the tubes are communicated with a boiler barrel, and the lower ends of the tubes are connected with a base. A super-heater tube bundle is arranged below the boiler barrel; two sides of the super-heater tube bundle are respectively arranged on a tube plate connected with a falling tube or a rising tube. An evaporator tube bundle is arranged below the super-heater tube bundle; two ends of each tube bundle layer of the evaporator are respectively communicated with two collecting boxes; and two ends of the collecting boxes are respectively communicated with the rising tube or the falling tube. A plugging mechanism is arranged in the rinsing tube and the falling tube. An economizer tube bundle is arranged below the evaporator tube bundle; and two sides of the economizer tube bundle are respectively arranged on the tube plate connected with the falling tube or the rising tube. The evaporator collecting box, the pipe plate, the sealing plate and the side plates of the boiler form a sealed cylindrical fume channel, a fume inlet pipe is arranged at the upper end of the channel, and a fume outlet pipe is arranged at the lower end. The corner-tube waste heat boiler provided by the utility model is low in manufacturing cost of apparatuses, small in volume, and convenient to install on site.

Description

A kind of corner tube type waste heat boiler
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: superheater, evaporimeter, economizer and support their steelframe.Its weak point is: evaporimeter links to each other with drum (drum) through outside connecting leg, so not only takes up room but also has improved equipment cost, causes unnecessary economic loss, does not also 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, corner tube type waste heat boiler little, compact conformation takes up room.The utility model mainly includes: drum, tedge and down-comer, superheater bank, evaporimeter tube bank, economizer tube bank and exhaust gases passes.Wherein, be distributed in four vertical pipes of four jiaos in this boiler, 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 superheater bank below the drum, the one of which side is on both sides and tube sheet that down-comer links to each other, and opposite side places on both sides and the tube sheet that tedge links to each other.Below above-mentioned superheater bank, be provided with one or more groups evaporimeter tube bank, preferably evaporimeter tube bank and inclined certain angle.
Preferably evaporimeter tube bank heat exchanger tube is provided with helical fin or fin outward.Every layer of tube bank of this evaporimeter two ends are connected with two collection casees respectively, and the two ends of this two collection case are connected with tedge or down-comer respectively again.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.Below the tube bank of above-mentioned evaporimeter, be provided with one or more groups economizer that is interconnected tube bank, the one of which side is on both sides and tube sheet that down-comer links to each other, and opposite side places on both sides and the tube sheet that tedge links to each other.Above-mentioned evaporimeter collection case, support superheater and the tube sheet of economizer and the sealing plate that the above two are linked to each other, they and boiler side plate surround an airtight tubular exhaust gases passes, and flue gas inlet tube is established in the passage upper end, and smoke outlet tube is established in the passage lower end.
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 weight of support own, 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.
Description of drawings:
Fig. 1 is that the utility model master looks simplified schematic diagram.
Fig. 2 is that the utility model is overlooked simplified schematic diagram.
The specific embodimentIn the simplified schematic diagram of a kind of corner tube type waste heat boiler illustrated in figures 1 and 2, be distributed in four vertical pipes of four jiaos in this boiler, their upper end is communicated with drum 1 and supports drum.In these four pipes, two is that 2, two of tedges are down-comer 3, and they and drum constitute circulation line.The lower end of above-mentioned four pipes all links to each other with the basis.Be provided with superheater bank 4 below the drum, on the tube sheet 5 that the one of which side links to each other with down-comer in both sides, opposite side places on the tube sheet 6 that both sides link to each other with tedge.Below above-mentioned superheater bank, be provided with 2 groups of tilting evaporimeter tube banks 7, evaporimeter tube bank heat exchanger tube is provided with helical fin outward.Every layer of tube bank of this evaporimeter two ends are connected with two collection casees 8 respectively, and the two ends of this two collection case are connected with tedge or down-comer respectively again.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.Below the tube bank of above-mentioned evaporimeter, be provided with 2 groups of economizers tube banks 9 that are interconnected, the one of which side is on both sides and tube sheet that down-comer links to each other, and opposite side places on both sides and the tube sheet that tedge links to each other.Above-mentioned evaporimeter collection case, support superheater and the tube sheet of economizer and the sealing plate 10 that the above two are linked to each other (in heat-insulation layer is arranged); They and boiler side plate surround an airtight tubular exhaust gases passes; Flue gas inlet tube 11 is established in the passage upper end, and smoke outlet tube 12 is established in the passage lower end.
