Embodiment 1

[0040] see Figure 1 to Figure 3 , The present invention provides a furnace door dust collecting cover, which is mainly composed of a top cover 1, a side baffle plate 2, and a rectangular tuyere 3, with a length of 8560 mm and a width of 2765 mm. Under the guidance of the top cover 1 and side baffles 2 and the negative pressure of the smoke exhaust pipe 4, the smoke concentrates in the same direction and reaches the rectangular tuyere 3, turns 90° and is sucked into the smoke exhaust pipe 4.

[0041] 1. The top cover 1 is used to block smoke and change the direction of smoke movement, and includes an upper guide plate 11 and an inclined baffle 12. The top cover 1 is in the shape of a trapezoid as a whole.

[0042] The upper guide plate 11 is composed of a rectangular top cover 111 and two right-angle trapezoidal side inclined covers 112 on the left and right. Wherein, the rectangular top cover 111 has a length of 5770mm and a width of 1542.8mm.

[0043] The inclined baffle 1...

Embodiment 2

[0055] The difference from Example 1 is that the furnace door dust collecting hood provided in Example 2 is mainly composed of a top cover 1, a side baffle 2, and a rectangular tuyere 3, with a length of 9416mm and a width of 3041.5mm.

[0056] Wherein, the top cover 1 includes an upper guide plate 11 and an inclined baffle plate 12, and the overall shape is trapezoidal. The upper guide plate 11 is composed of a rectangular top cover 111 and two right-angle trapezoidal side inclined covers 112 on the left and right. Wherein, the rectangular top cover 111 has a length of 6347 mm and a width of 1697.1 mm. The inclined baffle 12 is an inclined right-angle type baffle, and is composed of two parts: an inclined plate 121 and a right-angled plate 122 . Among them, the inclined plate 121 is directly connected with the upper end and the left and right ends of the upper guide plate 11. The height of the top cover 1 is 2689.5mm, the length of the upper bottom is 1697.1mm, the length of...

Embodiment 3

[0060] The difference from Example 1 is that the furnace door dust collecting hood provided in Example 3 is mainly composed of a top cover 1, side baffles 2, and a rectangular tuyere 3, with a length of 4708 mm and a width of 1520.75 mm.

[0061] Wherein, the top cover 1 includes an upper guide plate 11 and an inclined baffle plate 12, and the overall shape is trapezoidal. The upper guide plate 11 is composed of a rectangular top cover 111 and two right-angle trapezoidal side inclined covers 112 on the left and right. Wherein, the rectangular top cover 111 has a length of 3173.5mm and a width of 848.6mm. The inclined baffle 12 is an inclined right-angle type baffle, and is composed of two parts: an inclined plate 121 and a right-angled plate 122 . Among them, the inclined plate 121 is directly connected with the upper end and the left and right ends of the upper guide plate 11. The height of the top cover 1 is 1344.75mm, the length of the upper bottom is 848.55mm, the length ...

Abstract

The invention discloses a furnace door dust collection hood which comprises a top hood, side baffles and a rectangular air port, wherein the top hood is used for blocking smoke and changing the movement direction of the smoke, the side baffles are used for preventing smoke on two sides from overflowing, and the rectangular air port is used for collecting the smoke. The top hood comprises an upper guide plate and a sloping baffle, the upper guide plate is composed of a top cover and a side sloping cover, the side baffles comprise a left side baffle and a right side baffle, and the rectangular air port is formed in the top end inside the furnace door dust collection hood; under the guide function of the top hood and the side baffles and the function of negative pressure of a smoke discharge pipeline, the smoke intensively reaches the position of the rectangular air port in the same direction, rotates by 90 degrees and is sucked into the smoke discharge pipeline. The furnace door dust collection hood is capable of effectively preventing the smoke in front of a furnace from overflowing, reducing thermal radiation and energy waste, strengthening collecting ability of the smoke, and reducing secondary pollution, the occupied area, the investment cost and working burdens of a draught fan.

Description

technical field [0001] The invention relates to the technical field of metal smelting dust collection equipment, in particular to a furnace door dust collection cover. Background technique [0002] Environmental pollution is increasing day by day, and the harm it brings has attracted more and more attention. At present, environmental pollution has become an urgent problem that affects economic development, people's health and may have serious social impact. Air dust pollution is the source of pollution. one. [0003] At present, most of the furnace door dust collection hoods used in the domestic metal smelting field only cover a top cover directly above the furnace door, and do not build side baffles on both sides of the furnace door, resulting in serious leakage of flue gas on both sides of the furnace front. , resulting in environmental pollution, while increasing the waste of heat radiation and energy on both sides, affecting the production safety and personal health of ...
