Abstract
The utility model discloses an energy-saving and emission-reduction boiler, which comprises a boiler body and a smoke passage, wherein a gas and liquid heat exchanger and a dust remover are sequentially connected in series on the smoke passage, and a smoke gas propeller is arranged in the smoke passage arranged between the gas and liquid heat exchanger and the dust remover. The energy-saving and emission-reduction boiler of the utility model has the advantages of high after heat recovery rate, good dust removal effect, simple structure, easy manufacture and low cost.
Description
Technical field
The utility model relates to a kind of boiler, particularly relates to a kind of small-sized energy-saving and emission-reduction boiler.
Background technology
The UTILIZATION OF VESIDUAL HEAT IN problem of boiler is more and more paid attention to by people; The flue gas of boiler directly is discharged in the air, and is very big to the pollution of environment, also is subjected to paying close attention to more and more widely.But people generally pay attention to the energy-saving and emission-reduction problem of large medium-size boiler, and the numerous miniature boiler waste heat of on-hand quantity can not utilize, flue gas directly discharges, and in the market, the miniature boiler that waste heat energy utilization while flue gas discharges after purifying does not also have.Because the enormous amount of arcola, thereby the development and use of small-sized energy-saving and emission-reduction boiler have great importance.
Summary of the invention
The purpose of this utility model is to provide a kind of waste heat recovery rate the high energy-saving and emission-reduction boiler of good dedusting effect simultaneously.
The utility model is achieved by the following technical solution: the energy-saving and emission-reduction boiler, comprise body of heater and flue, be connected in series gas-liquid heat exchanger, deduster on the described flue successively, be provided with the flue gas propeller in the flue between described gas-liquid heat exchanger, the deduster.
Described gas-liquid heat exchanger is provided with the sealing radiator of flue for its inner chamber, and described flue communicates with flue, and described sealing radiator is provided with to have and closes water inlet and the delivery port that opens valve.
Described deduster is the water tank deduster, is provided with the dividing plate that has the passway in the described water tank, and described adjacent separator passway misplaces mutually, and an end of described water tank deduster communicates with flue, and the other end is provided with outlet flue.
Described flue gas propeller is a blower fan.
The outer wall of described heat exchanger is provided with one deck heat-insulation layer.
Described water tank deduster is provided with to have and closes water inlet and the sewage draining exit that opens valve.
The utility model is because the flue of the flue gas process gas-liquid heat exchanger in the flue, heat in the flue gas is just absorbed by the water in the gas-liquid heat exchanger water tank inner chamber, thereby water is heated, make original discarded fume afterheat major part obtain recovery, not only heated water also can be widely used in aspects such as washing, bathing, and can join and burn steam in the boiler, improve the boiler feed water temperature, save boiler heat time heating time, improve boiler efficiency, according to measuring and calculating, 16 meters long heat exchangers, the thermal efficiency can improve more than 40%; Perhaps, about fuel savings 45-50%.Simultaneously, flue gas is under the angle of rake effect of flue gas, enter the water tank deduster, flue gas passes through from water, by the fine particle of water filtering flue gas, flue gas after being purified is discharged by outlet flue, because flue gas is subjected to stopping of dividing plate, moves along the separator channels mouth, has prolonged the sedimentation time, be beneficial to purification, good dedusting effect.
The utility model has the advantages that waste heat recovery rate height, good dedusting effect, simple in structure, easy to manufacture, cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Number in the figure is: 1, body of heater; 2, flue; 3, gas-liquid heat exchanger; 4, flue; 5, flue gas propeller; Deduster; 7, dividing plate; 8, passway; 9, water inlet; 10, delivery port; 11, heat-insulation layer; 12, outlet flue; 13, sewage draining exit.
The specific embodiment
The utility model is described in further detail in conjunction with the specific embodiment with reference to accompanying drawing, but do not constitute restriction of the present utility model.
As shown in Figure 1, a kind of energy-saving and emission-reduction boiler comprises body of heater 1 and flue 2, is connected in series gas-liquid heat exchanger 3, water tank deduster 6 on the described flue 2 successively, and the flue 2 between described gas-liquid heat exchanger 3, the water tank deduster 6 is provided with blower fan 5; Described gas-liquid heat exchanger 3 is provided with the sealing radiator of four flues 4 for its inner chamber, described flue 4 communicates with flue 2, described sealing radiator is provided with to have and closes water inlet 9 and the delivery port 10 that opens valve, and the outer wall of described gas-liquid heat exchanger 3 is provided with one deck heat-insulation layer 11; The sectional area sum of described four flues 4 equates with the sectional area of described flue 2; Described water tank deduster 6 is a cuboid water tank, be provided with the dividing plate 7 that has passway 8 in the described water tank, described adjacent separator passway 8 misplaces mutually, one end of described water tank deduster 6 communicates with flue 2, the other end is provided with outlet flue 12, the upper end of described water tank deduster 6 is provided with to have closes the water inlet 9 that opens valve, and the lower end of described water tank deduster 6 is provided with to have closes the sewage draining exit 13 that opens valve.The utility model is when work, inject cold water in the water tank inner chamber of gas-liquid heat exchanger 3, inject water in the water tank deduster 6, flue gas is through flue 4, heat in the flue gas is just absorbed by the water in the gas-liquid heat exchanger 3 water tank inner chambers, thereby water is heated; After flue gas is discharged from flue gas smoke pipe 4, under blower fan 5 effects, enter water tank deduster 6, flue gas passes through from water, by the fine particle of water filtering flue gas, flue gas after being purified is discharged by outlet flue 12, because flue gas is subjected to stopping of dividing plate 7, moves along separator channels mouth 8, has prolonged the sedimentation time, the number of dividing plate 7 is many more, and clean-up effect is good more.The utility model has the advantages that waste heat recovery rate height, good dedusting effect, simple in structure, easy to manufacture, cost is low.
Certainly; under inventive concept of the present utility model, heat exchanger of the present utility model, water tank deduster can have multiple malformation, and this to those skilled in the art; read and need not pay creative work behind this specification and can reproduce, all within protection domain of the present utility model.
