Description
Technical Field
The utility model belongs to the technical field of gas steam injection boiler technique and specifically relates to a prolong water jacket furnace tobacco pipe life's combination chimney.
Background
The water jacket heating furnace mainly comprises a fire tube, a smoke tube, a heated coil, a shell, a chimney and accessories. The medium in the shell of the heating furnace is clean water, and the medium in the coil is usually water-containing crude oil. The working principle is that fuel is combusted in the fire tube to generate high-temperature flue gas, the high-temperature flue gas is heated by water around the fire tube and the fire tube, then the medium in the coil is heated in a water bath by the hot water, the temperature of the medium in the coil is raised, and the medium in the coil is usually high in pressure so as to be convenient for outward transportation.
In practical application, as the operation time of the heating furnace increases, the smoke tube perforation phenomenon occurs on part of the heating furnace, so that the production is influenced by the fault shutdown, the maintenance frequency increases, and the maintenance cost increases.
The water jacket heating furnace is generally a multi-smoke tube design scheme and aims to increase the convection heat exchange area of smoke tubes so as to improve the efficiency of the heating furnace. Through checking the perforation positions, the perforation is found to occur in the No. 1 smoke exhaust pipe at the bottom of the smoke pipe. And the perforation time mostly occurs in seasons with relatively low air temperature.
The water jacket heating furnace fuel is associated natural gas produced by oil wells, the main component of the associated natural gas is alkane, the combustion products are H2O and CO2, H2O starts to exist in a steam form, and the associated natural gas is cooled into liquid water in the process of rising along a chimney and flows down along the wall of the chimney. The flue gas contains certain sulfides which are reflected with liquid water to generate strong acid H2SO3, and due to design defects (the problem of backflow of condensed water is not considered), no flue baffle is arranged, SO that the acidic condensed water flows into the flue pipe along a chimney in a pouring manner, and the flue pipe is corroded to cause perforation. The corrosive debris on the inner wall of the chimney falls on the smoke pipe mouth to cause the terrain of the smoke pipe mouth to be higher, so that condensed water condensed in the chimney can more easily flow into the smoke pipe, but if the condensed water is not present, the corrosive debris is not generated. And observation and statistics show that the amount of corrosion debris of the chimney is different in the heating furnace with the perforated smoke pipe. Therefore, in order to prevent the acidic condensate water from flowing into the smoke tube, the main factor for solving the problem of too fast corrosion of the smoke tube is solved.
Application No.: 201220644157.4, filing date: 2012-11-29 discloses a non-corrosive chimney provided with a sandwich drainage structure. The corrosion-free chimney with the interlayer drainage structure comprises an outer barrel, an inner barrel and an interlayer arranged at a bracket between the outer barrel and the inner barrel, wherein a water collecting pit for collecting accumulated water in the interlayer is arranged at the bracket part of the outer barrel, and the bottom of the water collecting pit is communicated with an inner cavity of the chimney through a drainage pipe penetrating through the wall of the inner barrel. The utility model discloses bracket position between chimney urceolus and inner tube constructs an intermediate layer drainage structures with urceolus prevention of seepage, reaches the effect that the urceolus does not have the seepage, and the inner tube does not corrode. The structure consists of three parts, namely a partial waterproof coating on the inner surface of the outer cylinder, a short drainage pipe, a cover plate and the like. The structure is mainly applied to the design and the transformation of a chimney for rotationally discharging smoke, and ensures the all-weather safe operation of the chimney under special conditions, such as the condition that the construction process is not in place, the lining is cracked due to high-temperature thermal stress, and wet smoke enters the interlayer and forms condensed water under the extremely cold weather condition.
Application No.: 201721332206.X, filing date: 2017-10-16 discloses an environment-friendly chimney capable of preventing condensed water corrosion, and mainly relates to a chimney structure in smoke emission equipment. Including chimney main part, fixed baseplate, advance tobacco pipe way, drain pipe, dust filter and anti-backflow flange, chimney main part lateral wall is equipped with the condensate water chamber, is equipped with inlet tube and outlet pipe in the chimney main part, is equipped with first high temperature anticorrosive coating layer on the chimney main part inner wall, and the dust filter includes top annular collection liquid support, toper filter screen and bottom sprag support, advances the tobacco pipe way end and stretches into the inside 2 ~ 10cm of chimney main part, is equipped with annular drainage groove on the anti-backflow flange. The beneficial effects of the utility model reside in that: the content of smoke dust and the content of sulfide and nitride in the smoke gas can be reduced; the smoke entering the chimney main body from the smoke inlet pipeline is prevented from leaking into the atmosphere from the drain pipe; the condensed sewage formed in the chimney body is prevented from flowing down to the inner wall of the smoke inlet pipeline from the inner wall of the chimney body, so that the accumulated water and corrosion of the smoke inlet pipeline are avoided.
Application No.: 201320200668.1, filing date: 2013-04-20 relates to a boiler chimney condensed water collecting device, which comprises a transverse pipe (1) communicated with a boiler smoke outlet and a vertical pipe (2) communicated with a chimney, wherein the other end of the transverse pipe (1) communicated with the boiler smoke outlet is transversely inserted and extends into one section of the vertical pipe (2), the lower end part of the lower part of the position where the vertical pipe (2) is communicated with the transverse pipe (1) is closed and is provided with a bottom surface (21) located at the lowest point position, and a condensed water outlet (22) is arranged at the lowest point position of the bottom surface (21) of the vertical pipe (2).
