The specific implementation mode is as follows:
referring to fig. 1, 2 and 3, the dedusting and desulfurizing tower comprises a tower body 1, a spraying unit 2, a demister 3, a spraying zone 4 and a water-retaining chimney 5; the lower part of the tower body 1 is provided with an air inlet 11, the top part is provided with an air outlet 12, and the air inlet 11 is provided with a first spraying unit 2.
The spraying unit 2 comprises a spraying pipe 21 and a spray head 22 arranged on the spraying pipe, and the spraying pipe 21 is connected with an external water source through a water pipe; the water pipe drawing shows that the external water source refers to two types, namely a water source with dust and sulfide collected at the lower end of the tower body and a backflow water source recycled through precipitation; and secondly, tap water is used as a supplementary water source.
The spraying area 4 is arranged at the middle lower part of the tower body 1 and is composed of a plurality of vertically arranged pipelines 41, a gap is arranged among the plurality of pipelines 41, two ends of the plurality of pipelines are fixed on the baffle plates 42, an external closed space is formed by the upper baffle plate 42 and the lower baffle plate 42 and the outer surfaces of the pipelines, water drops in the tower body converge into water flow, and the water flow can flow along the wall, the baffle plates 42 at the upper end part and the lower part of the pipelines 41. The external closed space can be treated as follows: two air convection ports 13 are arranged on the tower body between the upper baffle plate 42 and the lower baffle plate 42, so that outside air can enter the tower body to form convection heat dissipation, and the temperature of flue gas can be further reduced, thereby being beneficial to dust removal, desulfurization and fog reduction.
Further, the diameter of the pipe 41 is between 15cm and 25cm, and the length of the pipe is between 70cm and 120 cm. The proper caliber can ensure the balance between the spraying uniformity and the pipe wall adsorption, and the length increases the adsorption opportunity and the heat dissipation area. And the tubing 41 may be selected from the following materials: a hose; PVC pipes; stainless steel tubes.
The upper part and the lower part of the spraying area 4 are respectively provided with a spraying unit 2; wherein, the spraying unit 2 arranged below the spraying area and the first spraying unit 2 arranged at the air inlet are connected with a backflow water source collected below the tower body 1 through a water pipe; the spray unit 2 arranged above the spray area 4 is connected with tap water through a water pipe, and the tap water is added with a desulfurizer to perform the last desulfurization and gas washing action on the first and second sprayed and dusted flue gas. As the water mist and the flue gas from top to bottom and from bottom to top form convection in the longer pipeline 41, the water mist and the flue gas are ensured to be fully contacted, and a better desulfurization and dust removal effect is achieved. And the white fog at the air outlet is restrained by using the lower and constant temperature of tap water.
Furthermore, a corresponding spray head 22 is arranged above the spray area pipeline 41, and the central axis of the spray head 22 is overlapped with the central axis of the pipeline 41, so that the water mist can cover and cover the opening of the pipeline and contact with the rising smoke.
A water retaining chimney 5 is arranged above the spraying area 4, and three to five water retaining chimneys 5 are uniformly distributed on the partition plate 52 at the middle upper part of the tower body 1; the top of the water-retaining chimney 5 is provided with a suspension cover 51, and flue gas can radially diffuse through a gap formed between the suspension cover 51 and the top of the water-retaining chimney. The smoke fog transversely diffused from the adjacent water-retaining chimneys 5 increases the chances of mutual collision and collision with the tower wall, improves the probability of condensation into water drops, and can prevent the smoke from directly rushing to the air outlet 12; and moreover, the small air mass can be promoted to be condensed into the large air mass, so that the adsorption by the demister 3 arranged between the upper part of the water retaining chimney 5 and the air outlet 12 is facilitated, the water content of the discharged flue gas is lower, and the emission of the tower body in a low-temperature environment is reduced to generate white fog.
