Description

Technical Field

[0001] The utility model relates to the field of double-layer chimneys, in particular to a prefabricated double-layer chimney which is convenient for intercepting dust. Background Art

[0002] A chimney is a structure that provides ventilation for hot flue gases or smoke from a boiler, furnace, stove or fireplace. Chimneys are usually vertical, or as close to vertical as possible, to ensure a smooth flow of gases, drawing air into the so-called chimney combustion or chimney effect. The space inside the chimney is called the flue, and chimneys are divided into single-layer chimneys and double-layer chimneys, while double-layer chimneys are composed of two layers, inner and outer, and the space between the two layers of chimneys is filled with insulation material to form a certain insulation layer.

[0003] After searching, a utility model chimney with the publication number of CN207599761U was found. The chimney includes a chimney body, a fixed short pipe and a fixed flange. The chimney body includes a carbon steel part and a first titanium metal plate stacked on each other and is provided with an opening penetrating the carbon steel part and the first titanium metal plate. The fixed short pipe is a titanium metal tube. The fixed flange includes a carbon steel plate and a second titanium metal plate stacked on each other. One end of the titanium metal tube passes through the opening and is sealed and fixed on the first titanium metal plate, and the other end passes through the carbon steel plate and the end is welded to the second titanium metal plate. Therefore, the chimney avoids direct contact between the flue gas and the chimney wall, fixed short pipe and fixed flange made of carbon steel by rationalizing the design of the joints and replacing the materials of the components, thereby improving the corrosion resistance of the chimney.

[0004] When the existing double-layer chimney discharges flue gas, a large amount of dust and powder particles will remain inside. However, the existing chimney currently has no good way to intercept the dust in the flue gas, so that the dust and powder enter the outside air, causing serious pollution to the surrounding air environment. In the above-mentioned comparative case, only the flange is used for assembly and the corrosion resistance is enhanced. However, the dust and powder remaining in the flue gas are still discharged into the outside air, causing pollution and affecting the ecological environment.

[0005] Therefore, it is necessary to invent a prefabricated double-layer chimney that is convenient for intercepting dust to solve the above problems. Utility Model Content

A water pump is fixedly installed on one side of the water tank, a delivery pipe is fixedly installed on one side of the water pump, and a sprinkler head is fixedly installed on the outside of one end of the delivery pipe.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 A prefabricated double-layer chimney convenient for intercepting dust shown includes a chimney body 1 for discharging smoke;

[0029] The discharge bin 3 is fixed on one side of the chimney body 1. Gauze 4 and mesh 5 are respectively arranged inside the discharge bin 3. The gauze 4 and mesh 5 are used to intercept dust in the flue gas. Inclined plates 6 are fixedly installed on both sides of the lower part of the discharge bin 3. A discharge port 7 is opened on the lower surface of the discharge bin 3.

[0030] A discharge pipe 8 is fixedly installed below the discharge bin 3 and is used to discharge water;

[0031] A water tank 16 is fixedly installed below the discharge pipe 8 for storing water. A water pump 17 is fixedly installed on one side of the water tank 16. A delivery pipe 18 is fixedly installed on one side of the water pump 17. A spray head 19 is fixedly installed on the outside of one end of the delivery pipe 18. The spray head 19 sprinkles water on the gauze 4 and the mesh cloth 5, and the attached dust and powder and water flow into the discharge pipe 8 at the same time. The dust is collected by the collection frame 13, and the flowing water finally returns to the water tank 16, thereby achieving the recycling of water resources.

[0032] like Figure 1 and Figure 2 As shown, the interior of the chimney body 1 is provided with an insulation layer 2, and the material of the insulation layer 2 is glass wool. Through the setting of the insulation layer 2, it can play a role in heat insulation, sound insulation and fire prevention, reduce heat loss and reduce energy consumption.

[0033] like Figure 1 and Figure 4 As shown, the outside of the discharge pipe 8 is sleeved with a clamp 9, and bolts 10 are passed through both sides of the clamp 9. The clamp 9 is sleeved on the outside of the discharge pipe 8 to enhance the stability of the discharge pipe 8 and avoid long-term exposure to the outside and the occurrence of shaking and damage caused by the influence of the external environment.

[0034] like Figure 1 and Figure 4 As shown, a slide groove 11 is provided on one side surface of the discharge pipe 8, and a slider 12 is movably connected inside the slide groove 11. A collection frame 13 is fixedly installed on one side of the slider 12. The setting of the slider 12 facilitates the collection frame 13 to be pulled out and cleaned of dust, and such a setting is convenient for the staff to collect and process dust.

[0035] like Figure 5 As shown, a filter screen 14 is provided inside the collection frame 13, and a handle 15 is fixedly installed in front of the collection frame 13. The filter screen 14 can filter the flowing water, so that dust remains in the collection frame 13, and the filtered water returns to the water tank 16.

[0036] like Figure 1 and Figure 3As shown, the input end and the output end of the water pump 17 are connected to the water tank 16 and the delivery pipe 18 respectively, and the spray heads 19 are evenly spaced on the delivery pipe 18. The water in the water tank 16 is pumped out by the water pump 17 and sprayed out through the spray heads 19, which not only improves the dust removal effect, but also has the effect of intercepting dust.

[0037] Working principle of the utility model: when the smoke is discharged from the chimney body 1, it enters the discharge chamber 3 through the smoke port on one side of the chimney body 1. When the smoke enters the discharge chamber 3, it will first contact the mesh 5, so that large particles of dust and impurities enter and are intercepted, and the gauze 4 above strengthens the interception of dust, and the filtered smoke is discharged from the discharge chamber 3, and the intercepted dust is attached to the gauze 4 and the mesh 5. Then, the external power supply is turned on, the water pump 17 is turned on, the water in the water tank 16 is pumped out, and the water is transported to the spray head 19 through the delivery pipe 18, and the water sprayed by the spray head 19 is poured on the gauze. The cloth 4 and the mesh cloth 5 are on the surface of the filter 14. The water flows into the discharge pipe 8 from the discharge port 7 together with the dust by gravity. The water and dust flowing down pass through the filter 14 in the collecting frame 13, and the dust is filtered and retained in the collecting frame 13. The filtered water returns to the water tank 16, thereby forming circulating water. After that, when it is no longer necessary to discharge the flue gas, turn off the water pump 17 switch, and then hold the handle 15 to pull the collecting frame 13 out of the discharge pipe 8, clean the dust in the collecting frame 13, and finally cut off the external power supply. In this way, the use process of the prefabricated double-layer chimney that is convenient for intercepting dust is completed.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
