Description
The utility model relates to a kind of boiler.
China's utility application discloses a kind of horizontal, reverse, quick-heating, atmospheric boiler capable of removing smoke and dust No. 93104842, this boiler includes body of heater, arch and oval water jacket, both sides and rear set box convection tube group and furnace base, and its water jacket is connected by connecting pipe with collection case convection tube group and constitutes the two return water route.On the arch water jacket, smoke barrier is installed, constitutes three backhaul cigarette roads.The mutual reverse flow in this boiler water route and cigarette road can improve heat exchanger effectiveness, and simultaneously, burner hearth and flue can not adopt refractory material, therefore has certain advantage.But the smoke-box that returns of this boiler partly is fixing enclosed construction, make, overhaul difficulty, thus the defective of existing.
The purpose of this utility model provides a kind of manufacturing and the horizontal easily normal-pressure hot-water boiler of maintenance.
The purpose of this utility model realizes in the following manner: in the rear end of drum detachable water leg is set, utilize the inner chamber of this water leg to form the folding smoke-box that is positioned at the back, combustion chamber, the flue gas that allows the combustion chamber overflow enters smoke pipe through this folding smoke-box, again by discharging behind the smoke pipe arrival chimney.Simultaneously, between water leg delivery port and drum water inlet, be provided with and be communicated with water pipe, allow cold water behind water leg, enter drum again.Specifically, horizontal normal-pressure hot-water boiler of the present utility model has drum, combustion chamber, smoke pipe and chimney, and its drum has water inlet and delivery port, and the tube chamber of drum constitutes the combustion chamber, and the front end of combustion chamber has fuel inlet.In the utility model, be provided with detachable water leg in the rear end of drum especially, this detachable water leg links to each other with drum through connector, constitute water leg folding smoke-box between the inner chamber of detachable water leg and the rear end of combustion chamber, smoke pipe passes the drum inner chamber and chimney is connected with water leg folding smoke-box, detachable water leg has water inlet and delivery port, and the delivery port of detachable water leg is connected through cross over pipe with the water inlet of drum.With regard to hot-water boiler of the present utility model, the water leg available metal at folding smoke-box place is made, need not adopt refractory material, thus all disadvantages that the folding smoke-box had of having avoided making with refractory material (as easily under the washing away of high-temperature flue gas deformed damaged, by the thermal effect difference etc.).Simultaneously, water leg is a detachable form, both has been convenient to make, and is convenient to boiler maintenance again.When using boiler, running water can enter drum through water leg earlier again, and the corresponding interior water body of water leg that utilizes fully absorbs fume afterheat, and the width of cloth that has increased boiler is penetrated heating surface area, helps improving heat exchange efficiency.In the utility model, the above-mentioned connector that detachable water leg is linked to each other with drum can be similar existing connectors such as bolt or ring flange.In addition, can be form of straight lines with chimney with the smoke pipe that water leg folding smoke-box is connected, also can be curve form, can also be the thickness pipe group form that the stage casing is provided with the turnover smoke box, promptly constitute two or more flue gas flows, with further reduction exhaust gas temperature.
Horizontal normal-pressure hot-water boiler of the present utility model compared with the aforementioned existing similar products has and is convenient to make and maintenance, characteristics that the thermal efficiency is high.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of hot-water boiler among the embodiment.
Fig. 2 is the A-A cutaway view.
As shown in Figure 1, 2, the hot-water boiler among the embodiment has drum 1, combustion chamber 2, smoke pipe 3,4 and chimney 5, and drum 1 has water inlet 6 and delivery port 7, and the tube chamber of drum 1 constitutes combustion chamber 2, and the front end of combustion chamber 2 has fuel inlet 8.Present embodiment is provided with detachable water leg 9 especially in the rear end of drum, this detachable water leg 9 links to each other with drum 1 through connector 16 (being ring flange) herein, constitute water leg folding smoke-box 10 between the rear end of the inner chamber of detachable water leg 9 and combustion chamber 2, described smoke pipe 3,4 passes the drum inner chamber and chimney 5 is connected with water leg folding smoke-box 10, detachable water leg 9 has water inlet 11 and delivery port 12, and the delivery port 12 of detachable water leg 9 is connected through cross over pipe 13 with the water inlet 6 of drum.In the present embodiment, for reduce exhaust gas temperature as far as possible, chimney 5 is arranged at the upper rear end of drum, front end middle and upper part at drum is provided with front smoke box 14, smoke pipe is divided into the first smoke pipe group 3 and the second smoke pipe group 4, water leg is rolled over smoke-box 10 to the first smoke pipe group 3 and front smoke box 14 is connected, and the second smoke pipe group 4 is connected front smoke box 14 with chimney 5.In the use of boiler, the high-temperature flue gas that fuel combustion produces enters water leg folding smoke-box 10 by the rear portion, combustion chamber, flows to the front portion through the first smoke pipe group 3, turn back by front smoke box 14, flow to the boiler rear end through the second smoke pipe group 4, discharge from chimney 5 again, formed three backhaul flue gas flows thus.In addition, the water inlet 6 of drum is positioned at the drum bottom in this example, and the delivery port 7 of drum is positioned at drum top.Feedwater enters the drum bottom by water leg delivery port 12, drum water inlet 6 after being entered by water leg water inlet 11 again, and hot water is then drawn by drum top.Pot water and flue gas reverse flow help exchange heat between the two.
Boiler in the present embodiment is the fuel oil type boiler, i.e. fuel inlet place in the combustion chamber is provided with oil burner 15.But, also be applicable to the coal boiler fully with regard to the utility model.When it is the coal boiler, only needs that the burning structure in this example is done corresponding change and get final product.
