Background technique
Currently, the industries such as chemical industry, building materials, printing and dyeing, food and hotel are all to generate heat with boiler to carry out product life
It produces, and fuel used in boiler is coal, gas and oil are raw material, it is especially too big due to burning coal pollution in city, environmental protection is not achieved
It is required that not allowing to burn, burning gas is at high cost, and many enterprises all use oil as fuel, and oil is divided into heavy oil and diesel oil again.
The fuel oil of oil burning boiler is sprayed by high-pressure oil pump indentation atomizer, and the air being sent into air blower is blended in burner hearth
Burning, ignition temperature are generally all burnt at 800~1000 DEG C.High-temperature flue gas by burner hearth internal pipeline heating surface two return or
After the heat absorption of three backhauls, enters chimney from flue and be discharged into atmosphere again, the smoke temperature in flue there are 300~400 DEG C at this time, from chimney
The smoke temperature of middle discharge also has 200~300 DEG C, these waste heats are just wasted in vain.Usually oil burning boiler is required in burning
Air and fuel oil can reduce furnace temperature when burning in burner hearth, general furnace temperature is all at 900 DEG C or so, and winter temperature is lower, due to furnace
Temperature is low to cause fuel burning insufficient, and chimney back warp is often emerged black smoke and green cigarette, and the thermal efficiency is very low, can bring dirt to city
Dye, is not achieved environmental requirement.And general boiler is after handling flue gas, can make for handle flue gas impurities in liquid gradually
Increase, so that the purification efficiency of boiler is lower and lower.
So needing a kind of energy-saving and environment-friendly flue gas waste heat recovery boiler to solve the problems, such as this.

End is fixedly connected, and 1 upper end of cabinet is equipped with lower end and penetrates cabinet 1 and extend to the air inlet pipe 7 of 1 inner underside of cabinet, and 1 upper end of cabinet is equipped with
Exhaust outlet 8, horizontal in cabinet 1 to be equipped with rotatable first straight tube 9 and the second straight tube 10, the left end of the first straight tube 9 is pierced by cabinet 1
Left end be connected to cold water pipe 11, the right end that the right end of the second straight tube 10 is pierced by cabinet 1 is connected to outlet pipe 12, the first straight tube 9
Right end is equipped with multiple U-tubes 13, and one end of U-tube 13 is connected to the first straight tube 9, the other end of U-tube 13 and the second straight tube 10
Connection；First straight tube 9 is equipped with first bevel gear 14, and level is equipped with the second cone tooth engaged with first bevel gear 14 in cabinet 1
Wheel 15, second bevel gear 15 is coaxially provided with the partial gear 16 above second bevel gear 15, and 1 upper end of cabinet is straight down
Equipped with shaft 17, the lower end of shaft 17 is equipped with turntable 18, and 18 lower end of turntable is equipped with the internal tooth that can be engaged with partial gear 16
Circle 19, shaft 17 are equipped with the cam 20 that is located at 18 top of turntable and can cooperate with baffle 4；1 right side lower end of cabinet is equipped with water outlet
Mouthfuls 21, the first electrically operated valve 22 is housed at water outlet 21.
1 upper end of cabinet is equipped with purifying box 23, is connected in the lower end of purifying box 23 and cabinet 1, purifying box 23 and case
Connectivity part is equipped with the second electrically operated valve 24 in body 1, has scavenging solution in purifying box 23.
First support 25 is equipped on the left of the cabinet 1, first support 25 is equipped with and is mounted on the first straight tube 9 and cold water pipe
First sealing flange 26 of 11 junctions；Second support 27 is equipped on the right side of cabinet 1, second support 27, which is equipped with, is mounted on second directly

In the use of the present invention, opening water inlet pipe 2, enters water and do not cross U-tube 13 in cabinet 1, it is electronic by controlling
Valve falls into the scavenging solution in purifying box 23 in cabinet 1 and incorporates in water, and the gas that boiler generates is led to by air inlet pipe 7
Enter in cabinet 1, because the bottom end of cabinet 1 is arranged in 7 outlet end of air inlet pipe, flue gas goes out the discharge of 7 outlet end of air inlet pipe, into cabinet 1 excessively
Interior solution filtering removes heavy metal in flue gas by the alkaline scavenging solution added from purifying box 23, is discharged, avoids from exhaust outlet 8
It is discharged to the health that people is endangered in air, while filtering dust particles in flue gas, reduces the discharge of pollutant, cold water pipe 11
With the connection of the first straight tube 9 so that cold water in cold water pipe 11 injects in the first straight tube 9, because the first straight tube 9 passes through U-tube 13
It being connected to the second straight tube 10, the amount of heat contained in flue gas exchanges heat in solution with the water in U-tube 13 in cabinet 1,
And because motor 30 drives the rotation of the first straight tube 9 to drive U-tube 13 to rotate, so that U-tube 13 and the water in cabinet 1 are abundant
Contact, can exchange heat to greatest extent, can save energy, increase the generation of downstream industry, extend production capacity, increase profit
Income.
When the time that device uses is longer, the liquid in cabinet 1 can be contained a large amount of impurities, when motor 30 passes through the second tooth
When wheel 31 drives first gear 29 to rotate, the first straight tube 9 drives U-tube 13 to rotate, and increases contact of the U-tube 13 with liquid, adds
The efficiency of fast heat exchange, when the rotation of the first straight tube 9, first bevel gear 14 drives second bevel gear 15 to rotate, second bevel gear
15 drive partial gear 16 to rotate, and when the first straight-bar rotates one week, partial gear 16 drives the rotation of ring gear 19 one
Fixed angle, can by practice or be calculated the liquid in cabinet 1 purification fail speed, control partial gear 16 tooth
Number controls the angle rotated with the coaxial mounted cam 20 of disk, when the outer circle of cam 20 and baffle 4 contact, i.e. cam 20
It is scheduled on the lower end of baffle 4, so that baffle 4 blocks water inlet pipe 2, when the inner circle of cam 20 goes to the position of baffle 4, baffle 4 exists
It is slided to the right under the action of spring 6, so that baffle 4 leaves water inlet pipe 2, controls the first electrically operated valve 22 at this time and release in cabinet 1
Water, can from water inlet pipe 2 by clean water inject cabinet 1 in, control the second electrically operated valve 24, by the purification in purifying box 23
Liquid is sent into cabinet 1, and the replacement of liquid in a cabinet 1 is completed.
The beneficial effects of the present invention are: flue gas can be made to go out the discharge of air inlet pipe outlet end, into solution filtering in cabinet is crossed, lead to
It crosses from medicament adding tube and adds alkaline solution, remove heavy metal in flue gas, it is avoided to be discharged to the health for endangering people in air,
Dust particles in flue gas are filtered simultaneously, reduce the discharge of pollutant, domestic water flows into pipe by cold water and flows into cabinet, flue gas
In the amount of heat that contains exchange heat in solution with the domestic water in heat exchanger tube in cabinet, save energy, increase downstream
The generation of industry extends production capacity, increases the income of profit, and by the replacement intracorporal liquid of case, so that cleaning efficiency improves simultaneously
Extend the use of device.
