The utility model provides a furnace end cigarette entrapment device.

The utility model provides a furnace end cigarette entrapment device is linked together with the coke oven, please refer to fig. 1, it includes collects cover 30 and a plurality of stove columns 10 along the straight line distribution, adjacent two be equipped with furnace gate 20 between the stove column 10. The collecting hood 30 is slidably disposed above a plurality of oven doors 20, so that the collecting hood 30 can slide above any one of the oven doors 20 to collect flue gas overflowing from the oven doors 20. In the present embodiment, it can be understood that the number of the oven doors 20 is multiple, and only one of the oven doors 20 is opened at the same time, before the oven door 20 is opened, the collecting hood 30 is moved to the position above the oven door 20 to be opened, and then the oven door 20 is opened, so that the smoke overflowing from the current oven door 20 can be collected and captured. Therefore, in the present application, even if there are a plurality of oven doors 20, there is no need to set a collection cover 30 on each oven door 20 for collection, and only the opening time of the oven doors 20 needs to be adjusted to stagger the opening times of the oven doors 20, so that the simultaneous operation of a plurality of oven doors 20 is not affected on the basis of reducing the number of the collection covers 30, and the operating efficiency of the coke oven is not reduced while the cost is reduced.

It can be understood that, in this embodiment, by providing a collection vehicle with a rail above the flue gas collection device and connecting the rail and the upper end of the collection hood 30 together, the collection hood 30 can be driven to move continuously,

referring to fig. 2, a flue is disposed in the collecting hood 30, an exhaust port 31 and an air suction port 32 both communicated with the flue are disposed at the top and the bottom of the collecting hood 30, respectively, and the exhaust port 31 is connected with an air duct of the main blower through an air duct. In this embodiment, the main blower is provided on the collection vehicle, and the end of the exhaust port 31 can be connected to the rail for movement. And since collection hood 30 needs to be moved, the flexible and foldable air ducts can be adopted to improve the flexibility of the air ducts, so that the possibility that the collection hood 30 is disconnected from each other when moving is reduced. The captured smoke is connected with the main fan air channel through the air pipe and is conveyed to external smoke purification treatment equipment for purification treatment.

Referring to fig. 2 again, the collecting hood 30 includes a collecting section 33 and a connecting section 34 connected to each other, the suction opening 32 is disposed at an end of the collecting section 33 far from the connecting section 34, and the exhaust opening 31 is disposed at an end of the connecting section 34 far from the collecting section 33. In this embodiment, the distance between the connecting section 34 and the furnace column 10 gradually increases along the vertical direction, that is, the connecting section 34 is disposed obliquely to the vertical direction, so as to avoid interference with the furnace column 10 and prevent damage caused by mutual collision of parts. In an alternative embodiment, the connecting section 34 and the collecting section 33 are detachably connected, so that they can be easily replaced and maintained, and different types of collecting sections 33 can be replaced to match different sizes of oven doors 20, so as to ensure the smoke collecting effect.

Further, referring to fig. 3, a left partition 35 and a right partition 36 are disposed in the collecting hood 30 to divide the flue into a middle chamber 37 and a left chamber 38 and a right chamber 39 disposed at two sides of the middle chamber 37. In this embodiment, the flue length of the middle chamber 37 is greater than the length of the oven door 20, the length of the air suction port 32 is 4500mm, the lengths of the left partition plate 35 and the right partition plate 36 from the two side chambers are 1000mm, the length of the middle chamber 37 is 2500mm, and the length of the oven door 20 is 1500mm, so when in use, the middle chamber 37 is located right above the oven door 20, and since the distance of the air suction port 32 of the middle chamber 37 is greater than the distance of the oven door 20, most of the smoke is sucked from the middle chamber 37, and a very small amount of smoke is absorbed by the left chamber 38 and the right chamber 39 on the two sides, so as to ensure that the smoke does not overflow.

In addition, in order to prevent the smoke from flowing out from the gap between the oven door 20 and the collecting hood 30, in an alternative embodiment, referring to fig. 2, a stopping bar 40 is provided on the oven column 10 above the oven door 20, and the end surface of the air suction opening 32 close to the oven column 10 is above the stopping bar 40. That is, in the present embodiment, the projection of the air inlet 32 on the horizontal plane overlaps with the projection of the barrier 40 on the horizontal plane, in other words, the flue gas will contact the barrier 40 after overflowing from the oven door 20, and will directly flow into the air inlet 32 to be captured under the blocking and guiding action of the barrier 40, so as to effectively improve the capture efficiency of the flue gas. Wherein, the lower wall surface of the baffle strip 40 is provided with an upward inclined guide surface to guide the smoke.

The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
