Abstract

The utility model provides a water-cooling structure of smoke box before boiler relates to boiler technical field, this water-cooling structure of smoke box before boiler, including furnace, after combustion chamber, preceding smoke box and the tobacco pipe that communicates after combustion chamber and preceding smoke box, the periphery of tobacco pipe is configured to the water storage district, supplies the circulating water inflow to flow its characterized in that: the front pipe plate of the front smoke box adjacent to the smoke pipe faces the water storage area, a water storage area is formed between the barrel of the front smoke box and the boiler barrel as well as between the barrel of the front smoke box and the boiler liner, and the water storage area is communicated with the water storage area; water can flow between the water storage area and the water storage area; firstly, can prevent that the preceding smoke box barrel from receiving high temperature and burning out, the heat that the flue absorbed the high temperature flue gas of turning has also been followed to the circulating water simultaneously, has not only reduced material loss and manual work, still makes boiler compact structure, has improved the thermal efficiency of boiler.

Description

Water cooling structure of boiler front smoke box

Technical Field

The utility model relates to the technical field of boilers, in particular to a water cooling structure of a front smoke box of a boiler.

Background

The smoke box is the turn passageway of fuel gas boiler flue gas flow, this place flue gas temperature is than higher, for example in the chinese patent of the grant publication number CN204345701U disclose a tube sheet protective structure of hot water boiler back combustion chamber, belong to the boiler field, the preceding smoke box at intercommunication tobacco pipe one end is sealed by the baffle, the temperature of preceding smoke box is higher, need to thicken the steel sheet to the processing, usually in order to prevent that the high temperature flue gas from burning out the steel sheet, generally beat refractory concrete in steel sheet department, in order to reach the effect of protection steel sheet, this technology is first to consume a large amount of refractory concrete, also consume a large amount of manual works simultaneously, still make the boiler smoke box bulky, the heat dissipation loss is big.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a water-cooling structure of smoke box before boiler aims at solving among the prior art preceding smoke box temperature higher, in order to prevent that the high temperature flue gas from burning out the steel sheet, need consume a large amount of concrete as the problem of insulating layer.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a water cooling structure of a boiler front smoke box comprises a hearth, a flashback chamber, a front smoke box and smoke tubes communicated with the flashback chamber and the front smoke box, wherein the peripheries of the smoke tubes are configured into a water storage area for circulating water to flow in and out, a front tube plate of the front smoke box adjacent to the smoke tubes faces the water storage area, a water storage area is formed between a barrel of the front smoke box and a boiler barrel and a boiler liner, and the water storage area is communicated with the water storage area; water may flow between the impoundment area and the storage area.

The utility model discloses a further technical scheme does, furnace's front end has the combustor installing port.

The further technical scheme of the utility model does, be provided with the inspection door of easy access on the flashback chamber.

The utility model has the advantages that:

because of the cooling of water, firstly, can prevent that the front smoke box from being burnt out by high temperature, the circulating water also can absorb the heat of high temperature flue gas from the turn flue simultaneously, has not only reduced material loss and manual work, still makes boiler compact structure, has improved the thermal efficiency of boiler.

Drawings

FIG. 1 is a schematic view of the internal structure of the present invention;

fig. 2 is a schematic view of a partial structure of fig. 1 according to the present invention.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, a water-cooling structure of a front smoke box of a boiler comprises a hearth 10, a flashback chamber 20, a front smoke box 40 and a smoke tube 30 communicating the flashback chamber 20 and the front smoke box 40, wherein the periphery of the smoke tube 30 is configured as a water storage area 50 for circulating water to flow in and out, the front smoke box 40 is adjacent to a front tube plate 41 of the smoke tube 30 and faces the water storage area 50, a water storage area 43 is formed between the smoke box body of the front smoke box 40 and a boiler body and a boiler furnace, and the water storage area 43 is communicated with the water storage area 50.

Because the water storage area 43 is communicated with the water storage area 50, the circulating water entering the boiler body exchanges heat with the smoke in the smoke pipe 30, the smoke entering the front smoke box 40 heats up the front smoke box, and meanwhile, the water in the water storage area 43 can play a water-cooling role in the front smoke box 40.

Specifically, the front end of the furnace 10 has a burner installation opening 11.

Specifically, the recombustion chamber 20 is provided with an inspection door 21 convenient for maintenance, so that the internal condition of the hearth can be conveniently inspected.

In the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
