Abstract
The utility model discloses an economizer for a biomass boiler. The economizer comprises a frame arranged in a tail flue of the biomass boiler, wherein 82 groups of coiled pipes are arranged in the frame in a staggered way, and are provided with water inlets and water outlets respectively; the water inlets of the coiled pipes are connected with a horizontally arranged inlet header, and the water outlets of the coiled pipes are connected with a horizontally arranged outlet header; each group of coiled pipes is 4,170mm long. According to the economizer, a space in the tail flue can be fully used for the heat exchange of the coiled pipes, so that the heat exchange area is enlarged, the heat exchange capability is further enhanced, the temperature of flue gas can be effectively reduced, the temperature of feed water of the biomass boiler can be increased, and effects of energy saving and emission reduction can be achieved; after the temperature of the flue gas is reduced, damage to a bag-type dust collector connected to the tail end of the flue can be reduced, the service life of the bag-type dust collector can be prolonged, so that the repair and maintenance workload can be reduced, and the cost can be lowered.
Description
Technical field
The utility model relates to biomass energy utilization technologies field, relates in particular to a kind of biomass energy boiler economizer.
Background technology
Along with the development of economic society, society is increasing to the demand of the energy, and conventional energy resource is day by day deficient, and the exploitation of new forms of energy are most important to the sustainable development of entire society, and the development and utilization of biomass energy becomes an important developing direction.
Economizer is a kind of visual plant of boiler energy-saving.Existing power plant biomass energy boiler, in its supporting back-end ductwork, economizer is installed, this economizer comprises framework, in framework, be provided with 76 groups of coiled pipes, each is organized coiled pipe and is staggered in arrangement, every group of coiled pipe is respectively equipped with water inlet and delivery port, and each water inlet of the organizing coiled pipe all inlet header horizontally disposed with is connected.The described length of respectively organizing coiled pipe is 3685 millimeters.Water obtains entering boiler after preheating in economizer, can reduce the energy consumption of boiler.
This economizer and biomass energy boiler and flue thereof adapt to part not at global existence, be embodied in: total heat exchange area is limited, exchange capability of heat is limited, the utilization rate of smoke heat energy is lower, under the exhaust gas temperature of existing biomass energy boiler and the condition of exhaust smoke level, after flue gas heat exchange, remaining temperature is higher.Flue end is connected with sack cleaner, when the flue gas of higher temperature is mingled with fine particle by dust-collecting bag, easily aggravates cloth bag damage, shortens its service life.
Utility model content
The purpose of this utility model be to provide a kind of heat utilization rate higher, can alleviate the biomass energy boiler economizer of sack cleaner damage.
For achieving the above object, biomass energy boiler economizer of the present utility model comprises the framework being located in biomass energy boiler back-end ductwork, is provided with 82 groups of coiled pipes in framework, and each is organized coiled pipe and is staggered in arrangement, and is respectively equipped with water inlet and delivery port.Each water inlet of the organizing coiled pipe all inlet header horizontally disposed with is connected, and each delivery port of organizing coiled pipe is all connected with a horizontally disposed outlet header; Each length of organizing coiled pipe is 4170 millimeters.
The utility model is simple in structure, is convenient to manufacture and use.The utility model has extended the length of coiled pipe, and heat exchange is carried out in the space that coiled pipe is made full use of in back-end ductwork; Owing to having increased the number of plies of coiled pipe, therefore heat exchange area of the present utility model further increases, and exchange capability of heat further strengthens, and can effectively reduce flue-gas temperature, improve the temperature of biomass energy boiler feedwater, reaches the effect of energy-saving and emission-reduction.Flue-gas temperature can reduce being connected to the damage of the sack cleaner of flue end after reducing, and extends the service life of sack cleaner, reduces maintenance, maintenance workload cost-saving.
In a word, the utility model can improve the temperature of biomass energy boiler feedwater, extends the service life of sack cleaner, reaches the technique effect of energy-saving and emission-reduction, cost efficiency.
Accompanying drawing explanation
Fig. 1 is schematic cross-section of the present utility model.
The specific embodiment
As shown in Figure 1, biomass energy boiler economizer of the present utility model is located at the framework 1 in biomass energy boiler back-end ductwork while comprising use, is provided with 82 groups of coiled pipes 2 in framework 1, and each is organized coiled pipe 2 and is staggered in arrangement, and is respectively equipped with water inlet 3 and delivery port 4.Each water inlet 3 of organizing coiled pipe 2 is all connected with a horizontally disposed inlet header 5, and each delivery port 4 of organizing coiled pipe 2 is all connected with a horizontally disposed outlet header 6; Each length L of organizing coiled pipe 2 is 4170 millimeters.
Described coiled pipe 2 adopts the manufacture of 20G steel pipe.
During use, the utility model is arranged in biomass energy boiler back-end ductwork, and the water supply of inlet header 5 is flowed out by outlet header 6 after each group serpentine coil.When high-temperature flue gas passes through the utility model from the bottom to top, carry out heat exchange with the water in each group coiled pipe 2, the water after intensification supplies water to biomass energy boiler by outlet header 6.The utility model has extended the length of coiled pipe 2, and heat exchange is carried out in the space that coiled pipe 2 is made full use of in back-end ductwork; Owing to having increased the number of plies of coiled pipe 2, therefore heat exchange area of the present utility model further increases, and exchange capability of heat further strengthens, and can effectively reduce flue-gas temperature, improve the temperature of biomass energy boiler feedwater, reaches the effect of energy-saving and emission-reduction.Flue-gas temperature can alleviate being connected to the damage of the sack cleaner of flue end after reducing, and extends the service life of sack cleaner, reduces maintenance, maintenance workload cost-saving.
