Abstract
The utility model provides a smoke pipe hot water boiler with anti-wearing sleeve and flow guide plate type boiler inner chamber to improve heat exchange efficiency of smoke pipe boiler, consisting of a boiler body, a smoke pipe, an anti-wearing casing and a flow guide plate. The flow guide plate is shaped like a reversed capital letter 'L' and is arranged at one side of the internal of the boiler cavity. The horizontal lower part of the flow guide plate is communicated with a water inlet, and the internal vertical part is communicated with a water outlet and has the same shape as the cavity of the boiler. The inlet of the smoke pipe is sheathed by an anti-wearing casing. The smoke pipe boiler with flow guide plate keeps the water flow in the boiler body even. A protecting casing is arranged at the mouth of the smoke pipe to prevent the smoke with dust from directly attacking the smoke pipe, thereby reducing failure rate of the boiler and lengthening the service life of the boiler.
Description
Technical field
A kind ofly set up deflector, to improve the smoke pipe hot-water boiler guide plate type boiler intracavity of flue tube boiler heat exchange effect at boiler intracavity.
Background technology
The smoke pipe hot-water boiler is the widely used boilers of industry such as heating.
Though boiler in the past can satisfy the requirement of recirculated water heating and safe handling,, make the interior recirculated water flow velocity difference of body of heater, even differ greatly because of its recirculated water flows to comparatively directly in body of heater.Water inlet and delivery port air line distance are than weakness, and flow velocity is very fast, and bending place and smoke pipe and tube sheet junction flow velocity are slower.Flow velocity is located soon, and heat exchange property is good, and can there be better guarantee in boiler performance and life-span; Flow velocity is located slowly, the heat exchange weak effect.When local temperature acquires a certain degree, can influence metal material performance and gyp situation, advancing you influences boiler failure rate and life-span.
In addition, flue gas flow rate is very fast in the smoke chamber, and contains more sand and dust.Impact smoke orifice fast, very easily cause the smoke orifice wearing and tearing, also influence boiler life.
Summary of the invention
The purpose of this utility model is the design of setting up deflector and setting up protection tube at the smoke orifice place by boiler intracavity, the interior circulating water flow of boiler is flowed by guide direction, thereby improve the uneven shortcoming of recirculated water flow velocity in the boiler; Make flue gas directtissima protection tube with the protection smoke pipe, advance you and reduce because of recirculated water flow velocity inequality, the fault that local heat exchange effect is bad and the smoke orifice wearing and tearing cause improves boiler service life.
The utility model is by body of heater, smoke pipe, Antiwear casing, and deflector is formed, and deflector becomes the type to be arranged on boiler intracavity one side, and the horizontal position bottom feeds the mouth of a river, the inboard pass-out of the vertical position mouth of a river, shape is consistent with boiler intracavity; The smoke pipe porch is set with Antiwear casing.
Antiwear casing port band protecting against shock dish.
Set up the flue tube boiler of deflector, after recirculated water flows into from import, can not directly flow to delivery port, and need along the guide plate guide direction, flow to the smoke pipe rear side, be back to the water outlet oral region along smoke pipe Shu Fangxiang then, discharge from delivery port, the interior water of body of heater is evenly flowed, substantially improve the heat exchange effect of each point in the body of heater; Set up protection tube at smoke orifice, make the flue gas of band sand and dust can not the directtissima smoke pipe, thereby reduce the fault rate of boiler, the service life of improving boiler.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, and wherein Fig. 1 is specification digest figure, and Fig. 2 is the side view of Fig. 1, and Fig. 3 is an Antiwear casing mounting structure schematic diagram.Each label is respectively among the figure: 1 body of heater, 2 smoke pipe bundles, 3 deflectors, 4 delivery ports, 5 Antiwear casings.
The specific embodiment
The utility model is described further now in conjunction with the accompanying drawings an example.Body of heater 1 diameter is 1800mm, long 6000mm; Smoke pipe bundle 2 is wide to be 1600mm, high 900mm, long 6020mm, single smoking pipe internal diameter 63mm, wall thickness 3.5mm; Deflector 3 horizontal front ends and furnace body inside front end are affixed, and fixing position is apart from body of heater 1 centerline 400mm, the vertically long 1200mm of horizontal segment; Type is identical in vertical section place external form and the body of heater 1, and seals affixedly, and indirect smoke pipe bundle 2 housings are made with the Q235 general steel plate; Antiwear casing 5 usefulness stainless steel materials are manufactured, wall thickness 1mm, external diameter 62mm; Protecting against shock dish diameter 78mm.
Claims (2)
1, a kind ofly sets up deflector at boiler intracavity, to improve the smoke pipe hot-water boiler guide plate type boiler intracavity of flue tube boiler heat exchange effect, by body of heater, smoke pipe, Antiwear casing, deflector is formed, and it is characterized in that: deflector becomes the type to be arranged on boiler intracavity one side, and the horizontal position bottom feeds the mouth of a river, the inboard pass-out of the vertical position mouth of a river, shape is consistent with boiler intracavity; The smoke pipe porch is set with Antiwear casing.
