Description

The invention relates to the field of energy and is intended for furnaces burning solid fuel. The present invention makes it possible to maximally remove heat from the chimney flue gas to clean it thoroughly from dust and soot. Spiral chimney for better traction has automatically controlled valves of new design. The spiral chimney is equipped with thermal tanks that allow the accumulated heat to be transferred to the thermal machines. The new design of the chimney ensures good traction under various ambient temperatures. Analogues of the invention could be inventions which attempt to extract heat either by means of a spiral tube inside a chimney patent CN 201311072 or simply by forming a chimney wall with water tanks patent DE 102007013840 Both of these patents address only the very narrow tasks of the chimney operation. In either case, it is not possible to extract the maximum heat from the smoke. Because in existing structures, water gradually warms up and starts to collect heat poorly. The structure for capturing heat is not well structured, either in space or in time. Spirals inside the stack hinder the free movement of gas. A chimney with an external heat sink will interfere with the smoke draft, forming a uniform temperature around the chimney. The construction and working principle of the present invention are quite different. The spiral chimney draws significantly more heat from the exhaust smoke. The chilled and heated chimney areas allow the draft to be adjusted at the desired speed, even in adverse environmental conditions. The damper and ejector system installed in the chimney allows maximum smoke removal from the particulate matter. The shape of the spiral chimney and the newly designed pipes ensure a fast and spontaneous draft of the smoke in the spiral.

The essence of the invention

The spiral chimney shape enables a lower chimney but with a longer path for the exhaust gas. This solution allows for better and more comprehensive smoke extraction, more heat recovery, and simple, fast flow movement. Bean tubes form clean gas streams. The existing system of ejectors and valves allows regulating gas velocity, precipitation of particulate matter and soot. Heat tanks placed in the middle of the chimney can accumulate much more heat. The accumulated heat is used for various household needs. Freezing and heating different areas of the chimney can accelerate or slow down the gas flow. These solutions allow the chimney to be operated even in adverse weather conditions.

The essential features of the invention are:

1. A chimney of spiral bean-shaped tubing, with a tapered upward cone cone, with a lower pressure at the upper and lower chimney sections and top filters to provide good draft and dust-free smoke.

2. The bean-shaped tubes are provided with adjacent tubes of the external heat carrier, which are further connected to the heat receptacles.

3. The cooling and heating modules inside the chimney are used to store heat from the rising smoke.

4. Cooling and Heating Modules Enable to regulate and accelerate draft by changing the temperature of individual chimney sections.

5. Traction can also be adjusted by various automatically controlled sliding, swivel, spiral, etc. the valves.

6. Stacked helical ejectors at the top of the chimney accelerate the escaping gas and precipitate solid smoke particles.

7. The chimney, in combination with thermodetectors and a computer program, controls the chimney flaps, heat transfer and cooling media flows.

8. Chimney heat tanks are connected to other external heat tanks and heat machines.

9. The spiral chimney can be connected to furnaces and other systems of various designs.

FIG. 1 General view of the chimney with the supporting body

The spiral chimney with supporting structure can be of various sizes and heights.

It depends on the design of the thermal reactor. A well-insulated chimney is connected to thermal machines. Thermal machines are marked with the M symbol. The heat exchange is marked with a Q symbol.

Fig.2 A) Spiral chimney

A chimney of spiral bean-shaped tubes 4, wound around a tapered upward cone, has a chimney having a wider lower part 6 and an upper part 5, with upper filter ejectors 8 providing good traction and dust-free smoke.

B) Chimney section showing the heat exchanger capacity inside the pipe The chimney draft is regulated by dampers. Upper spiral chimney flap 9 The lower spiral chimney flap 10 may operate individually or be controlled together in a coordinated program. The chimney may also have other sliding and swinging valves for small chimney diameters. Spiral valves 9,10 allow for a more accurate and better sealing of the chimney pipe cavity 4. Closed valves have tiny spaces left for safety reasons to prevent the accumulation of toxic gases. Inside the chimney are the heat exchanger capacities: the upper, internal refrigerated heat exchanger capacity 11 .the middle heat exchanger capacity 12, the lower, heated heat exchanger capacity 13, whose heat pipes 14 connect the chimney to the heat machine. External chimney flue heat exchangers with bean-shaped tubes 15. The chimney draft is regulated by opening the lower and upper chimney flaps 9,10, the chilled upper chimney, the inner chill heat exchanger 11 and the lower chill heat 13 respectively. the lower part of the stack. The difference in temperature between the top and bottom allows the gas to move upward in a spiral easily and quickly. Bean-shaped tubes give the gas a helical direction of movement. In addition, this form of chimney gas does not settle on the chimney walls due to additional internal turbulent vortices. The chimney runs long clean and fast. The upper and lower chimney parts 5,6 form a lower pressure, which further facilitates the evaporation of gas. The ejector 8 in the upper chimney filters serves several functions: accelerates the extraction of gas 16, enters additional air flow to the gas stream, provides additional acceleration, precipitates smoke of various sizes 17, and protects the upper part of the chimney from rain. Such a chimney design has good draft and clean smoke.
