Description

A kind of boiler afterheat recover
Technical field
The utility model relates to a kind of boiler afterheat recover.
Background technology
Boiler is to promote growth of the national economic, promotes society's one of imperative equipment of advancing, and is commonly used at aspects such as the industry of China and lives.Along with the development of society is arrived each link by widespread usage, be the capital equipment that consumes the limited energy.According to the interrelated data statistics, the coal consumption of boiler accounts for 80% of the whole nation year consumption coal energy.The supporting waste-heat recoverer of boiler design of the prior art is by boiler for producing producer and supporting professional production factory production, it is that iron casting becomes the elbow that utilizes cast iron 180 degree behind the U-shaped pipe, threeway etc. to assemble that great majority adopt materials, the heating surface area of this waste-heat recoverer is less, utilization rate of waste heat is not high, feed temperature is generally at 30~40 degrees centigrade, and waste-heat recoverer maintenance of the prior art is complicated, relative cost is higher, how to provide a kind of utilization rate of waste heat height and the waste-heat recoverer that is used for boiler with low cost to become the urgent demand of people.
Summary of the invention
The purpose of this utility model is to provide a kind of utilization rate of waste heat high and boiler afterheat recover with low cost.
The purpose of this utility model realizes by following scheme: a kind of boiler afterheat recover, it is characterized in that: described boiler afterheat recover comprises the housing of a sealing, in described housing, be provided with the front smoke chamber that is mutually independent, Heat Room and rear smoke chamber, described Heat Room is between described front smoke chamber and described rear smoke chamber, described front smoke chamber middle part is provided with dividing plate, described front smoke chamber is divided into last smoke-box and the following smoke-box that is mutually independent by described dividing plate, the bottom of described Heat Room and top are respectively arranged with evenly distributed some first heat conduction smoke pipes and some second heat conduction smoke pipes, described smoke-box down is communicated with the bottom of described rear smoke chamber by the described first heat conduction smoke pipe, the top of described rear smoke chamber is communicated with the described smoke-box of going up by the described second heat conduction smoke pipe, described smoke-box down is provided with gas approach, the described smoke-box of going up is provided with exhanst gas outlet, the lower end of described Heat Room is provided with the admission port, and the upper end of described Heat Room is provided with delivery port.
Described admission port is provided with water-supply valve.
Described delivery port is provided with outlet valve.
The lower end of described rear smoke chamber is provided with the dedusting mouth.
Advantage of the present utility model is: the utility model can be according to the landform field fabrication, increase by 2 to 3 hot sides extremely than supporting waste-heat recoverer in the prior art, the waste heat of flue gas is fully recycled, effectively improves feed temperature, feed temperature can reach 50-90 degree centigrade, improve 30-50 degree centigrade than waste-heat recoverer of the prior art, this can replace the boiler reserve feed tank, gets final product energy savings, reduces cost, can reduce by one 3-5 square metre feed-tank again, reduce equipment volume.Simultaneously, of the present utility model simple in structure, with low cost, be easy to large-scale promotion application.
Description of drawings
Fig. 1 is the structural representation of boiler afterheat recover of the present utility model.
In Fig. 1, include:
Front smoke chamber 1; Heat Room 2; Rear smoke chamber 3; Following smoke-box 4; Last smoke-box 5; Dividing plate 6; The first heat conduction smoke pipe 7; The second heat conduction smoke pipe 8; Gas approach 9; Exhanst gas outlet 10; Admission port 11; Delivery port 12; Housing 13; Dedusting mouth 14.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of boiler afterheat recover, the housing 13 that comprises a sealing, in housing 13, be provided with the front smoke chamber 1 that is mutually independent, Heat Room 2 and rear smoke chamber 3, Heat Room 2 is between front smoke chamber 1 and rear smoke chamber 3, front smoke chamber 1 middle part is provided with dividing plate 6, front smoke chamber 1 is divided into last smoke-box 5 and the following smoke-box 4 that is mutually independent by dividing plate 6, the bottom of Heat Room 2 and top are respectively arranged with evenly distributed some first heat conduction smoke pipes 7 and some second heat conduction smoke pipes 8, following smoke-box 4 is communicated with the bottom of rear smoke chamber 3 by the first heat conduction smoke pipe 7, the top of rear smoke chamber 3 is communicated with last smoke-box 5 by the second heat conduction smoke pipe 8, following smoke-box 4 is provided with gas approach 9, last smoke-box 5 is provided with exhanst gas outlet 10, and the lower end of Heat Room 2 is provided with admission port 11, and the upper end of Heat Room 2 is provided with delivery port 12.
In the utility model, admission port 11 is provided with water-supply valve.Delivery port 12 is provided with outlet valve.The lower end of rear smoke chamber 3 is provided with dedusting mouth 14.
The smoke pipe of boiler smoke-box directly is connected with the gas approach 9 of boiler afterheat recover of the present utility model.During work, the flue gas of boiler enters down smoke-box 4 by gas approach 9, and flue gas enters into rear smoke chamber 3 by the first heat conduction smoke pipe 7, under the effect of air blast, enters smoke-box 5 by rear smoke chamber 3 by 8 circulations of the second heat conduction smoke pipe again, and the back is got rid of by exhanst gas outlet 10.When using, reality exhanst gas outlet 10 directly can be docked with the deduster import.Cut down in the admission port 11 of the lower end of Heat Room 2 by feedwater and in Heat Room 2, to feed water, water is finished heat exchange in Heat Room 2 after, discharge by delivery port 12.Delivery port 12 can directly dock with the boiler hot water pump, supplies with hot water to boiler drum.
