COMPACT SMOKE OR AIR DILUTER FOR HIGH-TEMPERATURE FLUE GAS AND CONTAMINATED AIR

Abstract

Compact smoke or air diluter for high-temperature flue gas and contaminated air for being mounted at the top of or integrated in a chimney stack or a ventilation system that dilutes and dissipates high-temperature flue gas or contaminated air in the atmosphere, and ensures a normative draw/sub-atmospheric pressure defined on the basis of preceding requirements to or from connected functional applications consisting of cooling unit/ventilator part: Cooling pipe 9 mounted inserted in cooling top 12. Motor 1 mounted in interior cooling cup 4. The motor shaft is caused to continue out through a circular opening at the bottom of interior cooling cup 4 in a dimension that allows cooling air to pass below the motor 1, past the motor shaft, and out through the opening to exterior cooling cup 5. Between the bottom of interior cooling cup 4 and exterior cooling cup 5, there is, on the motor shaft, securely mounted a cooling medium 8. Through a hole at the bottom of exterior cooling cup 5, the motor shaft is caused to continue, where, at the end, there is mounted a ventilator medium holder 11, on which the ventilator medium 3 is mounted.

Claims

2. A smoke or air diluter according to claim 1, wherein the motor is provided with one or more ventilator media for moving and distributing high-temperature smoke and/or contaminated air, and is protected by a heat shield.

3. A smoke or air diluter according to claim 1, wherein there is, in air intake, below ventilator medium, secured one or more baffle plates in the form of inwardly facing, upwardly oriented rings for conveying air into the air column of high-temperature smoke or contaminated air from the chimney or the ventilation system and up to the ventilator medium.

4. A smoke or air diluter according to claim 3, wherein the baffle plates have an inclination relative to the longitudinal direction of the unit, which inclination is between 20° and 60°, or between 40°-50°.

5. A smoke or air diluter according to claim 1, wherein either in or to the unit, one or more cabled or wireless electric, electronic or computer-controlled components are provided for control, registration, reporting, safety, logging and communication.

6. A smoke or air diluter according to claim 1, wherein the unit comprises a heat shield whose outer diameter approximately corresponds to or is larger than the diameter of the stub of the bottom flange for deflecting heat from high-temperature flue gases and contaminated air and for deflecting down-fallen rainwater.

7. A smoke or air diluter according to claim 1, wherein the top of the unit is provided with a shield device.

8. A smoke or air diluter according to claim 1, wherein the unit is provided with a shield device at the air intake.

9. A smoke or air diluter according to claim 1, wherein in the unit, before and/or after ventilator medium, a filter device may be provided.

10. A smoke or air diluter according to claim 1, wherein in the unit, one or more ventilator media may be provided, wherein between the ventilator media, a filter device is provided.

11. A smoke or air diluter according to claim 1, wherein the smoke or air diluter has an external cylindrical shape or an external shape which is adapted to the chimney or the ventilation system on which or in which the smoke or air diluter is mounted.

12. A smoke or air diluter according to claim 1, wherein at the top of the pipe, mounted in a top ring, a shield device is provided.

13. A smoke or air diluter according to claim 12, wherein the top ring, with shield device, is provided with a suspension chain or wire which is secured to the outside of the pipe.

14. A smoke or air diluter according to claim 1, wherein interiorly of the pipe, a thin, resonance-dampening material is provided.

15. A smoke or air diluter according to claim 1, wherein in the cooling unit/the ventilator medium, outlying cooling pipes are arranged that, at their outwardly oriented ends, protrude outside or are flush with the pipe.

16. A smoke or air diluter according to claim 1, wherein the cooling pipes are, on the downwardly facing face, protected by deflector means.

17. A smoke or air diluter according to claim 1, wherein in the inwardly facing end in the cooling unit/ventilator part, outlaying cooling pipes are arranged that end in an air intake at the motor.

18. A smoke or air diluter according to claim 1, wherein on the device, energy absorbers, energy accumulation applications, and control or regulation for driving the electric, electronic and data-controlled components of the device are mounted.

Description

[0027] The invention will be described in further detail in the following with reference to FIG. 1:

[0028] Sectional view of cooling unit/ventilator part: Cooling pipe 9 mounted inserted in cooling top 12 which, on threaded spacer element 13 with welded exterior cooling cup 5, fixates both interior cooling cup 4 and exterior cooling cup 5. Motor 1 is mounted in interior cooling cup 4 by means of spacer thread 7 attached to motor 1 and at bottom of interior cooling cup 4 by means of screws. The motor shaft is conveyed through a larger circular opening at the bottom of interior cooling cup 4 of a dimension that allows cooling air to pass underneath the motor 1 and further out through the opening to exterior cooling cup 5. Between the bottom of interior cooling cup 4, and exterior cooling cup 5, there is, on the motor shaft, securely mounted a cooling medium 8. The cooling medium 8 draws the cooling air through the interior cooling cup 4 in which the motor 1 is arranged, and presses the cooling air on down through the opening at the bottom of the interior cooling cup 4 and out into the space between the internal cooling cup 4 and the external cooling cup 5 to the cooling medium 8 that is arranged on the through-going motor shaft in the space of the interior cooling cup 4 and the exterior cooling cup 5. The cooling air is pressed, via the cooling medium 8, on into the space between interior cooling cup 4 and exterior cooling cup 5, and up along the sides between the walls of interior cooling cup 4 and exterior cooling cup 5. Then the cooling air debouches into the space between interior cooling cup 4 and exterior cooling cop 5, at the top below cooling top 12, and out into the admixed atmospheric air/smoke or contaminated air. The motor shaft is caused to continue through a hole at the bottom of exterior cooling cup 5, on which shaft there is, at the end, mounted a ventilation medium holder 11 by which the ventilator medium 3 is secured by means of a screw that has been conveyed through the centres of the ventilator medium 3 and the ventilator medium holder 11 and up into an internal thread in the motor shaft.

[0029] FIG. 2:

[0030] Sectional view of the device that consists of: pipe 14 provided with top ring 10 by means of flaps 15 for securing on pipe 14 by means of screws. Cooling pipe slots 16 at the top of the pipe 14 for lowering of cooling pipe 9 from cooling unit/ventilator part. Below cooling unit/ventilator part there is, on a heat shield 19, securely mounted a safety grid 18. The lowermost part of the pipe 14 is perforated by air intake 17 for drawing in dilution air. The pipe 14 is, down below, secured to an exchangeable bottom flange 20 by means of hinge 21 and a hinge bolt 22.
