Problems solved by technology

[0002] Lime kilns commonly used in the prior art generally include a lime material feeding device, a furnace body, a hearth arranged on the furnace body, a slag discharge device and a burnt quicklime collection device. After the corresponding combustion materials are burned in the hearth The generated smoke is then discharged from the furnace body. On the one hand, because the smoke takes away part of the heat, the heat generated by the combustion of the combustion material cannot be completely used for calcining the lime material, and the smoke emitted causes heat loss. and waste of resources. On the other hand, related smoke is emitted into the atmosphere, polluting the air, which is not conducive to environmental protection
[0003] Based on the above-mentioned defects, at this stage, there are also smokeless emissions. The basic method is to install a smoke purification device at the smoke discharge port, such as passing the relevant smoke into the water with liquid medicine for atomization, precipitation and absorption. This method does not cure the symptoms. To solve the root cause, the related smog cannot be recycled into renewable energy, and the cost of purifying the smog needs to be increased
[0004] At the same time, the lime kiln in the prior art, even if the addition of combustion materials is accelerated, it generally cannot be quickly calcined lime materials to prepare burnt quicklime, because the yield of burnt quicklime is low, in order to reduce costs, It also does not intermittently add combustion materials
Furthermore, the lime kiln in the prior art, on the one hand, cannot achieve energy saving and environmental protection;

Embodiment 1

[0063] combine figure 2 and image 3 as shown,

[0064] The furnace wall 2021 in this embodiment is composed of two refractory brick wall panels formed into an inverted V shape, and the bottom ends of the two refractory brick wall panels forming an inverted V shape are connected to the two ends of the fire grate 2022 respectively. connected into one body so that the furnace 202 is formed into a Mitsubishi columnar structure; A small hole through which the flames of the burning material inside are ejected.

[0065] In this way, when the limestone material is calcined by the present invention, two refractory brick wall panels formed into an inverted V shape are used as the furnace wall 2021 of the furnace 202. On the one hand, the combustibles in the furnace 202 are burned The flame can be ejected from the small hole on the refractory brick wallboard to calcine the corresponding limestone material. On the other hand, the limestone material in the cylindrical furnace body 10 ...

Embodiment 2

[0067] combine Figure 4 and Figure 5 shown;

[0068] The furnace wall 2021 in this embodiment is composed of two inverted V-shaped refractory furnace bars provided with stepped water circulation flat iron pipes 209, and the bottom ends of the two refractory furnace bars forming an inverted V shape are respectively connected to The two ends of the fire grate 2022 are integrated so that the furnace 202 is formed into a Mitsubishi columnar structure; The lower end of the outer side of the bar is inclined, and the inside of the stepped water circulation flat iron pipe 209 is connected. A water outlet, the water outlet is connected with a water outlet pipe 210, and the water outlet pipe 210 penetrates to the outside of the furnace body base 20; there is a water outlet between the adjacent water circulation flat iron pipes 209 to make the combustion in the furnace 202 The gap where the flames of burning objects are ejected.

[0069]In this way, when the limestone material is c...

Embodiment 3

[0071] combine Figure 6 and Figure 7 shown;

[0072] The furnace wall 2021 in this embodiment is made of a conical refractory brick wall, and the bottom end of the conical refractory brick wall is integrated with the fire grate 2022, so that the furnace 202 It is formed into a three-dimensional conical structure; and the conical refractory brick wall surface is provided with a plurality of flames inclined to the outer lower end of the conical refractory brick wall surface so that the combustibles in the furnace 202 can be burned Jetted holes.

[0073] In this way, when the limestone material is calcined by the present invention, the conical refractory brick wall is used as the furnace wall 2021 of the furnace 202. On the one hand, the flame burned by the combustibles in the furnace 202 can be The corresponding limestone materials are sprayed out from the small holes on the wall of the refractory bricks. On the other hand, the limestone materials in the cylindrical furnace...

Abstract

The invention discloses a smokeless lime kiln continuously adding comburents by means of furnace fireguard combustion. The smokeless lime kiln continuously adding comburents by means of furnace fireguard combustion comprises a cylindrical furnace body, a furnace body base, a lime material loading device and a smoke cycle collection device, wherein the furnace body base is communicated with the cylindrical furnace body, a hearth is arranged in the furnace body base and comprises a furnace wall and a grate, a furnace slag discharge hole is formed below the grate, and a slag discharge pipeline penetrating out of the furnace body base is connected at the furnace slag discharge hole; a furnace opening is formed in the sidewall of the furnace body base; a gap between the furnace wall of the hearth and the sidewall of the furnace body base is formed to be a quick lime discharge hole, and a quick lime discharge pipeline penetrating out of the furnace body base is connected at the quick lime discharge hole; the smoke cycle collection device comprises a smoke discharge pipeline, a smoke exhaust machine and a speed regulation motor; the smoke inlet end of the smoke discharge pipeline is communicated with the cylindrical furnace body, and the smoke discharge end of the smoke discharge pipeline is arranged in the hearth; during implementation, the waste heat of the discharged smoke is recycled, and thus the purposes of smoke-free discharge, energy conservation and environmental friendliness, improvement of production efficiency and the like can be achieved.

Description

technical field [0001] The invention relates to the technical field of lime kiln equipment, in particular to an anthracite lime kiln which adopts a furnace rack combustion method and continuously adds combustible flue gas for circular combustion. Background technique [0002] Lime kilns commonly used in the prior art generally include a lime material feeding device, a furnace body, a hearth arranged on the furnace body, a slag discharge device and a burnt quicklime collection device. After the corresponding combustion materials are burned in the hearth The generated smoke is then discharged from the furnace body. On the one hand, because the smoke takes away part of the heat, the heat generated by the combustion of the combustion material cannot be completely used for calcining the lime material, and the smoke emitted causes heat loss.
