Description
Technical field
The utility model relates to industrial equipment field, is specifically related to a kind of novel mechanism of bayonet pipe boiler of water-tube waste heat.
Background technology
Waste heat recovery not only can bring the economic benefit of energy aspect, can also reduce environmental pollution; Waste heat boiler is the visual plant of the waste heat producing steam in next life utilized in industrial processes, is widely used in the Waste Heat Recovery of the chemical industry such as coal gasification industry, ammonia synthesizing industry, ethene, sulfuric acid, nitric acid industry or petrochemical industry; Waste heat boiler is arranged in all types of industries flow process, for recovery waste heat, is improving the thermal efficiency of single unit system, is reducing environmental pollution and meet some technological requirement aspect, playing a very important role.Traditional fixed tube sheet type waste heat boiler is provided with thick tube sheet in high-temperature region, needs to compensate the relative elongation because the temperature difference produces, outer tube by the restriction of tube sheet, cannot free-extension, needs expansion compensation structure.Biased flow phenomenon in tradition mechanism of bayonet pipe waste heat boiler water tank makes feedwater not be assigned in inner sleeve uniformly, cause the flow dead in carbonated drink case, the seal structure complex of waste heat boiler housing, outer tube is connected with thick tube sheet easily to be revealed, outer sleeve bottom plug place easily accumulates foreign material, recirculated water is flowed worsen, cause sleeve end cool bad and burn out.
Summary of the invention
The utility model provides a kind of mechanism of bayonet pipe boiler of water-tube waste heat, is applicable to oil plant heavy oil catalytically cracking equipment flue gas waste heat recovery system heat exchanger and Large Scale Ammonia synthesizer Efficient Heat Transfer Exchanger used.Effectively can solve the complex structure that traditional waste heat boiler has, heat energy utilization is not high, connects defective tightness, easily aging problem.
To achieve these goals, the technical solution adopted in the utility model is: it is made up of housing 1, erosion-resistant refractory lining 2, lacing wire 3, tube bank 4 and header 5; Housing 1 comprises upper cover 11, upper cover sleeve pipe 12, cylindrical shell 13, low head 14 and to the passive skirt 15 of equipment, wherein upper cover sleeve pipe 12 is welded on the shaped telescopic tube on upper cover 11, to weld with end socket for preventing sleeve pipe reveal with the sleeve pipe of end socket weld on leave the inspection opening of Φ 3; Erosion-resistant refractory lining 2 be the inner surface of upper cover 11, cylindrical shell 13 and low head 14 pour into a mould one deck thicker there is castable that is wear-resisting and heat-resistant quality; Lacing wire 3 is arranged on connector drum 13 and tube bank 5 in cylindrical shell, restrains the part of 4 vibrations, be generally arranged on and restrain 5 bottom end near heat exchanger tube when preventing waste heat boiler from working; Tube bank 4 and header 5 are major parts that this mechanism of bayonet pipe boiler of water-tube waste heat is different from traditional mechanism of bayonet pipe heat exchanger; Tube bank 4 is made up of outer tube 41, inner sleeve 42, spheric end part plug 43, plug blowdown apparatus 44, protective casing 45, gaseous mixture fairlead 46; Header 5 distributes header 51 by feedwater, steam water interface outlet header 52 forms; Down-comer 61, tedge 62 connect to form boiler water cycle system with drum.
Principle of the present utility model is: header 5 distributes header 51 and steam water interface outlet header 52 because its effect difference is divided into feeding water.Feedwater distributes header 51 and is mainly used to the water of drum down-comer 61 again to mix and is assigned in each inner sleeve 42; Steam water interface outlet header 52 is mainly used to collect the steam water interface come from different outer tube 41, and enters tedge 62 after being mixed by steam water interface.Double hose feedwater distributes header 51 and adopts down-comer 62 to introduce structure from header 5 center, down-comer 61 distributes header 51 center of pipe from a feedwater to be introduced, the feedwater of another root distributes header pipe 51 and does not introduce down-comer 61, two feedwater distribute between header 51 and connect with 180 ° of large elbows, and other end end socket seals.The feedwater of this double hose distributes header 51 and generally adopts tilt layout.The feedwater not introducing down-comer 62 in this layout distributes header pipe in downside, and the feedwater introducing down-comer 61 distributes header pipe in upside.From header 5 center deriving structure after steam water interface outlet header 52 all adopts multitube carbonated drink to converge, tedge 62 is drawn in the upper end center perforate of single cell, and introduce outer tube 41 fairlead in the lower end of pipe and lateral opening hole, pipe two ends end socket seals.Contain the tube bank 4 of many group different sizes in mechanism of bayonet pipe boiler of water-tube waste heat, and often group tube bank 4 be furnished with a feedwater distribution header 51 and a steam water interface outlet header 52.The pipe number often organizing tube bank of described multi units tube bundle 4 is equal, and in tube bank 4, the position of pipe is different; And same size tube bank 4 is even number set, they are arranged symmetrically with in heat exchanger.Requiring the pipe number often organizing tube bank equal is to make each group pipe Inner eycle water flow velocity in tube bank close, reducing Bottomhole pressure difference.Tube bank 4 is main heat exchange sections of this waste heat boiler, restrains 4 one end and inserts in housing 1 as bayonet, and the other end passes upper cover sleeve pipe 12, and by outer tube 41 and upper cover sleeve pipe 12 reducing welding edges; After described inner sleeve 42 passes upper cover sleeve pipe 12 together with outer tube 31, at distance upper cover sleeve pipe 12 reducing one segment distance place, the spheric end part plug end 43 of outer tube 31 end and perforate is welded, inner sleeve 42 and the end part plug 43 through spheric end part plug 43 perforate is welded at tapping simultaneously and form outer tube 41 top seal; Outer tube 41 sealed bottom is formed at outer tube 41 bottom welding spheric end part plug 43.Because described tube bank 4 stretches into housing comparatively deeply, the hot high-temperature technology gas of import can directly wash away tube bank 4, causes this place's heat exchanger tube burning and erosion corrosion, occurs on this position heat exchanger tube install protective casing 45 additional for avoiding above-mentioned situation.Inner sleeve 42 is being connected through distributing header 51 with feedwater after spheric end part plug 43 perforate.Outer tube 41 is connected with steam water interface outlet header 52 by its side gaseous mixture fairlead 46.Inner sleeve 42 and outer tube 41 is characterized in that inner sleeve 42 stretches in outer tube 41 and form annular space, at the gusset that the outside of inner sleeve 42 equally spaced welding circumferencial direction is uniform, make inner sleeve 42 be stabilized in outer tube 41, independent inner sleeve 42 does not occur and vibrates.Bottom outer tube 41, spheric end part plug 43 place easily accumulates foreign material, recirculated water is flowed and worsens, and causes sleeve end cool bad and burn out.For above problem, the utility model increases a blowdown apparatus 44 at each outer sleeve bottom plug 43.
The utility model beneficial effect is: structure is relatively simple, and heating rate utilizes high, connects closely, not easily aging.
