Description

A kind of novel industrial boiler that reduces heat-energy losses

Technical field

The utility model belongs to the Industrial Boiler that generally uses in the petroleum and petrochemical industry, and what be specifically related to is a kind of novel industrial boiler that reduces heat-energy losses.

Background technology

Boiler is the compositions such as the combustible element carbon in the fuel, hydrogen to be combined with oxygen chemical reaction occurs under hot conditions, emit heat, and then again with this heat transferred water, water is heated up become hot water or steam, equipment for the user, therefore, boiler is a kind of equipment that the chemical energy of fuel is converted into heat energy.Industrial Boiler is important thermal powerplant.Existing Industrial Boiler comprises combustion chamber, hot hydroecium, smoke pipe, smoke pipe spirals in hot hydroecium, smoke pipe one end communicates with the combustion chamber, the smoke pipe other end stretches out hot hydroecium and links to each other with air exhauster, during exchange heat, a large amount of heat energy distributes in air from outer wall and the smoke pipe outside the hot hydroecium of combustion chamber, causes heat-energy losses, the heat energy of fuel combustion can not be fully used, waste the energy.

Summary of the invention

The purpose of this utility model provides a kind of novel industrial boiler that reduces heat-energy losses, and it is used for solving the large problem of existing Industrial Boiler thermal loss.

The technical scheme that its technical problem that solves the utility model adopts is: this novel industrial boiler that reduces heat-energy losses comprises combustion chamber, hot hydroecium, smoke pipe, the combustion chamber links to each other with smoke pipe, smoke pipe spirals in hot hydroecium, and the smoke pipe end stretches out hot hydroecium and links to each other with air exhauster; Outer wall of combustion chamber is around the preheating tank, and up and down two interlayers that the preheating tank is adjacent communicate from beginning to end, and the water inlet of cold water pipe and preheating tank communicates, and the delivery port of preheating tank communicates with hot hydroecium by the preheating water pipe, and the preheating water pipe is outside equipped with heat-insulation layer; Smoke pipe outside the hot hydroecium is equipped with intercalated water sleeve outward, and the water inlet of intercalated water sleeve connects cold water pipe, and the outlet pipe of intercalated water sleeve is connected to hot hydroecium and communicates with hot hydroecium, and the outlet pipe of intercalated water sleeve is outside equipped with heat-insulation layer; Hot hydroecium's outer wall is provided with heat-insulation layer.

Intercalated water sleeve snaps together formation by two intercalated water sleeve halfbodies in the such scheme, and after two intercalated water sleeve halfbodies snapped together, the centre was through hole, and the smoke pipe outside through hole and the hot hydroecium is complementary; Contacted position was equipped with the water hole after two intercalated water sleeve halfbodies fastened, and two intercalated water sleeve halfbodies communicate by the water hole.

The utlity model has following beneficial effect:

The utility model cold water is preheated in preheating tank and intercalated water sleeve at first respectively before entering hot hydroecium, can take full advantage of the heat of combustion chamber, and the heat of smoke pipe outside the hot hydroecium, avoided the heat of combustion chamber to scatter and disappear by outer wall, also solved simultaneously the problem that the heat of smoke pipe scatters and disappears by tube wall outside the hot hydroecium, the heat that fuel combustion is produced fully utilizes, but energy savings is avoided waste.

Description of drawings

Fig. 1 is structural representation of the present utility model.

1 combustion chamber, 2 fuel nozzles, 3 hot hydroecium, 4 smoke pipes, 5 preheating tanks, 6 cold water pipes, 7 preheating water pipes, 8 intercalated water sleeves, 9 outlet pipes, 10 air exhausters, 11 heat-insulation layers, 12 boiler exports.

The specific embodiment

By reference to the accompanying drawings the utility model is described further:

As shown in Figure 1, this novel industrial boiler that reduces heat-energy losses comprises combustion chamber 1, hot hydroecium 3, smoke pipe 4, and combustion chamber 1 links to each other with smoke pipe 4, and smoke pipe 4 spirals in hot hydroecium 3, smoke pipe 4 ends stretch out hot hydroecium 3 and link to each other with air exhauster 10, and air exhauster 10 is extracted flue gas and be discharged in the atmosphere out; Combustion chamber 1 is provided with fuel nozzle 2, combustion chamber 1 outer wall is around preheating tank 5, preheating tank 5 adjacent up and down two interlayers communicate from beginning to end, the water inlet of cold water pipe 6 and preheating tank 5 communicates, the delivery port of preheating tank 5 communicates with hot hydroecium 3 by preheating water pipe 7, preheating water pipe 7 is outside equipped with heat-insulation layer, on the preheating water pipe 7 control valve is installed; Hot hydroecium's 3 outer smoke pipes are equipped with intercalated water sleeve 8 outward, and the water inlet of intercalated water sleeve 8 connects cold water pipe, and the outlet pipe 9 of intercalated water sleeve 8 is connected to hot hydroecium 3 and communicates with hot hydroecium 3, and outlet pipe 9 is outside equipped with heat-insulation layer, on the outlet pipe 9 control valve is installed; Hot hydroecium 3 is provided with Pressure gauge, safety valve, boiler export 12, and hot hydroecium's outer wall also is provided with heat-insulation layer 11, further to prevent thermal loss.
