Abstract

The utility model relates to a kind of boiler flue drip-proof structure flange, be used on the horizontally disposed flue of gas fired-boiler, heating furnace, the lower inside flue of each flange is welded with water fender, the condensation globule formed in flue is under the stop of water fender, make condensed water cannot flow into flanged seam place to cause dripping outside flue, but flow to the emission point of specifying along flue inside, no longer drip down from flange connections, drop onto ground or equipment surface, avoid the pollution to equipment surface and environment.

Description

A kind of boiler flue drip-proof structure flange

Technical field

The utility model relates to a kind of small gas boiler, heating furnace boiler flue drip-proof structure flange.

Background technology

In the last few years, along with people are to the raising of energy-saving and cost-reducing consciousness, the producer of various boiler plant turns down exhaust gas temperature in design all consciously, to obtain higher equipment thermal efficiency, so lower flue gas there will be when being discharged by flue and chimney the phenomenon being condensed into water droplet or emitting white cigarette.Taking natural gas as the boiler of fuel, the very clean and environmental protection of its fume emission, so from equipment de-sign to installation, all attach most importance to energy-efficient, between boiler to chimney, different according to installation environment, horizontally disposed flue is always had to connect, and often adopt the connection of form of flanges, this flange is generally steel plate excision forming flange, sealing surface is coarse and do not carry out machined, the sealing surface of flange generally can be provided with sealing gasket, the effect of sealing some flue gases can be played, but the effect of sealed condensating water liquid cannot be played, lower exhaust gas temperature often causes forming condensed water liquid in flue inner wall, can flow to outside flue along the seam crossing of flange, particularly low temperature season in the winter time, often dripping phenomenon is there is in the bottom of flue adpting flange, the general all once yellow liquids because of the corrosion composition containing flue inner wall of this condensed water, scatter on equipment or ground, cause equipment and ground contaminated, affect equipment appearance and contaminated environment, embacle is formed on ground time serious, very large trouble is caused to the maintenance of operating environment and equipment, obstacle.

Summary of the invention

The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of boiler flue drip-proof structure flange, effectively prevent condensed water and directly drop onto equipment surface and ground, the equipment that preventing drips causes, environmental pollution along flue flange lower joint place.

For achieving the above object, the technical scheme that the utility model is taked is: a kind of boiler flue drip-proof structure flange, be used on the horizontally disposed flue of gas fired-boiler, heating furnace, flange appearance and conventional flange to manufacture and design requirement identical, but be welded with water fender on the lower inside flue of each flange.The condensation globule formed inside flue, under the stop of flange port bottom water fender, cannot continue the sealing surface flowing to flanged seam, thus thoroughly avoids the problem of dripping at flanged seam place, and the condensed water piled up in flue flows to the discharge outlet of specifying along flue inside.

Further, described water fender is semicircle form, is arranged on the generation of flange lower inside and stops that namely the structure of condensed water and water conservancy diversion effect is applicable to the utility model.

Further, described water fender and the connection between explosion proof door are not limited to the form of welding, and namely both be applicable to the utility model by any type of effect being connected to form this programme.

The beneficial effects of the utility model are: on flange lower inside flue, welded water fender, the cost of cost is very low, make the condensation globule that flue gas produces when running into the lower flue of temperature, by the effect of water fender, make condensed water cannot flow into flanged seam place to cause dripping outside flue, but flow to the emission point of specifying along flue inside, no longer drip down from flange connections, drop onto ground or equipment surface, avoid the pollution to equipment surface and environment, avoid winter carries out deicing work at flue flange lower ground, the attached performance of the equipment that improves, reduce the maintenance workload of equipment operations staff.

Detailed description of the invention

Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

Embodiment 1: with reference to shown in Fig. 1, a kind of boiler flue drip-proof structure flange, horizontal flue 1 is linked together by flue flange 3 and fastening bolt 2, completes the normal connection of flue, the underflue at flue flange 3 place is welded with water fender 4.The condensation globule 5 of horizontal flue 1 inwall, under the stop of water fender 4, cannot ooze outside flue from flange seal again.

Embodiment 2: identical with embodiment 1, with reference to shown in Fig. 2, water fender 4 semicircular in shape shape, be welded on the flue of flue flange 3 bottom, water fender 4 adopts continuous welding.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.

Claims

1. a boiler flue drip-proof structure flange, is used on the horizontally disposed flue of gas fired-boiler, heating furnace, it is characterized in that: on the underflue at flue flange (3) place, be welded with water fender (4).

2. boiler flue drip-proof structure flange according to claim 1, is characterized in that: described water fender (4), for semicircle, be welded on flue flange lower inside and stop condensed water flowing.
