Abstract
The utility model belongs to the field of bottom-blowing furnaces, and particularly relates to a connecting device for a water jacket water pipe of a smoke outlet of a bottom-blowing furnace, which comprises a smoke outlet and a water pipe welded at the smoke outlet.
Description
Technical Field
The utility model relates to the technical field of bottom-blowing furnaces, in particular to a connecting device for a water jacket water pipe at a smoke outlet of a bottom-blowing furnace.
Background
At present, a smoke outlet water jacket of a bottom blowing furnace is formed by splicing four water jackets cast by copper-steel composite materials, each water jacket is independent, and when the bottom blowing furnace is used in production and operation, the bottom blowing furnace is provided with a water outlet pipe and a water inlet pipe which have four groups of eight pipes. During bottom-blowing furnace production, because the sulfur dioxide in the flue gas can contact the air and generate sulfur trioxide corrosion by chance, the ash pile causes water jacket water piping connection position the phenomenon of leaking often to appear, and the maintenance difficulty easily appears the water jacket and cuts off the water supply accident, directly causes the burning loss of outlet flue water jacket, seriously influences the life of outlet flue water jacket, hardly satisfies bottom-blowing furnace eighteen months's production cycle.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects in the prior art and provides a connecting device for a water jacket water pipe of a smoke outlet of a bottom blowing furnace.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the connecting device for the water jacket water pipe of the smoke outlet of the bottom blowing furnace comprises the smoke outlet and a water pipe welded at the smoke outlet, and is characterized in that the water pipe is an arc buffer elbow, and a protective sleeve is sleeved outside the water pipe.
Preferably, liquid water is arranged in the water pipe.
Preferably, a steel guard plate is arranged outside the smoke outlet, and the protective sleeve is welded on the steel guard plate on the smoke outlet.
Preferably, the material of the protective sleeve is 310S.
Preferably, the length of the protective sleeve is not less than 400mm, and the gap between the protective sleeve and the water pipe is not more than 3 mm.
According to the connecting device for the water jacket water pipe of the smoke outlet of the bottom blowing furnace, the smoke ash can be effectively prevented from being piled at the connecting opening, smoke can be effectively prevented from directly contacting the connecting opening, furnace body steel is welded and connected, the temperature of the sleeve is high, sulfur trioxide is not easily produced at the connecting opening, and the corrosion of the connecting opening is effectively reduced.
Drawings
FIG. 1 is a schematic structural diagram of a connecting device for water jacket pipes of a smoke outlet of a bottom-blowing furnace.
In the figure: 1 protective sleeve, 2 water pipe, 3 liquid water.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1, the connecting device of the water jacket water pipe of the smoke outlet of the bottom blowing furnace comprises the smoke outlet and a water pipe 2 welded at the smoke outlet, and is characterized in that the water pipe 2 is an arc buffer elbow, and a protective sleeve 1 is sleeved outside the water pipe 2.
In the present invention, liquid water 3 is provided in the water pipe 2.
In the utility model, the steel guard plate is arranged outside the smoke outlet, and the protective sleeve 1 is welded on the steel guard plate on the smoke outlet.
In the utility model, the material of the protective sleeve 1 is 310S.
In the utility model, the length of the protective sleeve 1 is not less than 400mm, and the clearance between the protective sleeve 1 and the water pipe 2 is not more than 3 mm.
According to the utility model, the protective sleeve 1 is welded on the steel guard plate on the smoke outlet, the other end of the protective sleeve is fully welded with the water pipe, and the protective sleeve is integrally plugged, so that the welding position is well sealed, firm and firm, the smoke ash can be effectively prevented from being piled at the connecting position, the smoke can be effectively prevented from directly contacting the connecting position, the furnace body steel is welded and connected, the sleeve is high in temperature, the sulfur trioxide is not easily produced at the position, and the corrosion of the connecting position is effectively reduced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
