Abstract
The utility model relates to an energy-saving coal economizer for a boiler, which belongs to the field of smoke-gas temperature-reducing devices, and comprises snake-shaped pipes, wherein the snake-shaped pipes are installed in a flue, and the snake-shaped pipes are connected with a circulating system. The energy-saving coal economizer for the boiler is characterized in that: four to five groups of snake-shaped pipes are arranged in the flue, the snake-shaped pipes are supported by supporting rods, and the snake-shaped pipes are communicated with the circulating system through pipelines. After one to two groups of snake-shaped pipes are added, the temperature-reducing effect of smoke gas is enhanced, the coal-economizing effect is improved, and the effect of energy saving is remarkable.
Description
Technical field
The utility model provides a kind of boiler energy-saving economizer, belongs to reduce flue-gas temperature device field.
Background technology
Steam power plant generally is provided with economizer for energy-conservation in the discharge-channel of high-temperature flue gas.Generally be arranged in the hard well after convection pass is turned, flue gas is walked between pipe, and soft water is walked in the pipe, constitute by a series of snakelike heat exchange tubes and collection case, adopt parallel-connection structure between the heat exchanger tube, make level fork row and be arranged in the flue, the collection case generally is arranged in outside the furnace wall, and collection case and heat exchanger tube are in the furnace wall external welding.Soft water order from bottom to top enters drum by the outer inlet header case of furnace wall, the heat exchanger tube in the flue, the outer outlet collection case of furnace wall, and flue gas from top to bottom skims over the heat exchanger tube surface, by tube wall directly heat transferred soft water.Two kinds of fluids of soft water and flue gas are separated into two passages by the heat exchange tube wall.Existing general employing 2-3 group structure, the efficiency of heating surface is not high, and the economizer effect is undesirable.
The utility model content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: provide a kind of reduction flue-gas temperature effective, energy-conservation tangible boiler energy-saving economizer.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of boiler energy-saving economizer, comprise coiled pipe is installed in the flue, coiled pipe connects the circulatory system, it is characterized in that: 4-5 group coiled pipe is set in the flue, coiled pipe is fixed by support bar, and coiled pipe is by the pipeline connection circulatory system.
Increase after the 1-2 group coiled pipe, increased the cooling-down effect of flue gas, improved province's coal effect.
Wherein preferred version is:
The inherent coiled pipe of described flue top is provided with a circulation bend, circulation bend communication loop system.The convenient circulatory system that connects improves cooling-down effect.
The beneficial effect that the utility model boiler energy-saving economizer is had is: 4-5 group coiled pipe is set in the flue, coiled pipe is fixed by support bar, coiled pipe is by the pipeline connection circulatory system, increase after the 1-2 group coiled pipe, increased the cooling-down effect of flue gas, improved province's coal effect, energy-conservation obvious.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, coiled pipe 2, support bar 3, flue 4, the circulatory system.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Embodiment 1:
As shown in Figure 1,4-5 group coiled pipe 1 is installed in the flue 3, coiled pipe 1 is fixing by support bar 2, and coiled pipe 1 is by the pipeline connection circulatory system 4.
Embodiment 2:
Flue 3 inherent coiled pipes 1 top is provided with a circulation bend, circulation bend communication loop system 4.The convenient circulatory system that connects improves cooling-down effect.The circulation bend just can be the part of coiled pipe, also can be coil pipe.
The coiled pipe 1 and the circulatory system are common prior art in the utility model, its setting and use to industry technical staff and grasped.
Operation principle and use:
Hot flue gas is by flue 3 coiled pipe 1 zone of entering.Water in hot flue gas and the coiled pipe 1 carries out heat exchange, increases after the 1-2 group coiled pipe, has prolonged coiled pipe and flue gas contact distance, has increased thermal energy exchange, has increased the cooling-down effect of flue gas, has improved province's coal effect.
