Technical Field
[0001] The utility model relates to the technical field of coke ovens, in particular to a coke oven smoke detection device. Background Art
[0002] When the coke oven is in use, smoke is discharged. The smoke contains many harmful substances, which will pollute the environment. In order to ensure that the smoke emission meets the environmental protection requirements, the smoke from the coke oven will be tested. If it does not meet the standards, the smoke from the coke oven will be treated and then discharged after it meets the standards. The existing smoke detection device has a single function, and the temperature of the smoke from the coke oven is relatively high. The existing smoke detection device does not have the function of cooling the high-temperature smoke in advance. Due to the high temperature, the high-temperature smoke is easy to cause wear and tear of the smoke detection device, thereby reducing the service life of the smoke detection device.

DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0017] Example 1
[0018] Reference Figure 1-3A coke oven smoke detection device comprises a smoke detector 1, a first air inlet pipe 2 is fixed on the smoke detector 1, a cooling mechanism is fixed on the first air inlet pipe 2, the cooling mechanism comprises a coolant storage box 3, a fixing frame 4 is fixed on the coolant storage box 3 and the smoke detector 1, the first air inlet pipe 2 passes through the bottom wall of the coolant storage box 3 and extends to the inside of the coolant storage box 3, a second air inlet pipe 7 is fixed on the first air inlet pipe 2 in the coolant storage box 3, a control valve 8 is fixed on the second air inlet pipe 7 outside the coolant storage box 3, the second air inlet pipe 7 is fixed at the coke oven smoke sampling location, and through the control of the control valve 8, the coke oven smoke will not enter the smoke detector 1 through the second air inlet pipe 7 when the coke oven smoke does not need to be detected.
[0019] A diffusion mechanism is fixed between the first air intake pipe 2 and the second air intake pipe 7. The diffusion mechanism includes a cylinder 5. An annular cavity 6 is provided inside the cylinder 5. The first air intake pipe 2 and the second air intake pipe 7 are both fixed on the cylinder 5, and the first air intake pipe 2 and the second air intake pipe 7 are both connected to the cavity 6. The coke oven flue gas enters the annular cavity 6 through the second air intake pipe 7. In addition, the cylinder 5 is made of heat-conducting material, and the coke oven flue gas dispersed in the cavity 6 will exchange heat with the coolant in the coolant storage box 3 over a larger area.
[0020] When in use, the coolant in the coolant storage box 3 covers the cylinder 5, the control valve 8 is opened, and the coke oven smoke enters the cavity 6 through the second air inlet pipe 7, and the coke oven smoke is dispersed in the cavity 6 inside the cylinder 5, so that the cooling area of the dispersed smoke and coolant in the cavity 6 is larger, and the coke oven smoke in the cavity 6 in the cylinder 5 is cooled in all aspects, and the cooling of the coke oven smoke is faster.
[0021] Example 2
[0022] In Example 1, the coolant in the coolant storage tank 3 needs to cover the cylinder 5, which results in a large amount of coolant consumption. Figure 1-3 As another preferred embodiment of the utility model, the difference from embodiment 1 is that the coolant storage box 3 is open, and a plurality of second shunt pipes 12 are equidistantly arranged outside the cylinder 5, and a plurality of first nozzles 13 are fixed on each second shunt pipe 12. The plurality of second shunt pipes 12 are commonly fixed with a ring-shaped first shunt pipe 11, and a liquid supply mechanism is fixed on the first shunt pipe 11. The liquid supply mechanism is fixed on the inner bottom wall of the coolant storage box 3. The liquid supply mechanism drives the coolant in the coolant storage box 3 to spray onto the outer circumferential side wall of the cylinder 5. The coolant in the coolant storage box 3 does not need to submerge the cylinder 5, which will reduce the amount of coolant in the coolant storage box 3 and reduce the cost of using the coolant.
[0023] The liquid supply mechanism includes a pump 9, which is fixed on the inner bottom wall of the coolant storage box 3. A first pipe 10 is fixed to the pump 9 and the first diversion pipe 11. A second pipe 14 is fixed to the first diversion pipe 11. A third diversion pipe 15 is fixed to the second pipe 14. The third diversion pipe 15 is coaxially inserted into the interior of the cylinder 5. A plurality of second nozzles 16 are evenly distributed and fixed on the third diversion pipe 15.
[0024] When in use, the liquid level of the coolant in the liquid storage box 3 is below the cylinder 5, and the pump 9 is started. The pump 9 allows the coolant to enter the first branch pipe 11 through the first pipe 10, and the coolant in the first branch pipe 11 enters the second pipe 14 and multiple second branch pipes 12. Finally, the coolant is sprayed onto the outer wall and inner wall of the cylinder 5 through multiple first nozzles 13 and multiple second nozzles 16, so that the cooling area of the flue gas and coolant dispersed in the cavity 6 is larger, and the coke oven flue gas in the cavity 6 in the cylinder 5 is cooled in all aspects, and the cooling of the coke oven flue gas is faster. At the same time, while the coolant is sprayed, the coolant can also be in contact with the air over a larger area, so that the heat of the coolant itself is also dissipated. In addition, after the sprayed coolant falls, the coolant in the coolant storage box 3 is also stirred, so that the temperature of the coolant is more uniform, thereby improving the cooling effect of the coolant on the coke oven flue gas.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
