Abstract

The utility model relates to a wet type desulfurizing dust collector, particularly the structural improvement of a dust collector in a boiler flue, which solves the problem that the past dust collector has poor dust collecting and desulfurizing effect. The wet type desulfurizing dust collector is composed of a water pool body, a base, a flow guider, a Venturi pipe, a barrel body, a water separator, smoke inlet and outlet pipes, a water inlet pipe and a manhole. The utility model has the advantage of obvious dust collecting and desulfurizing effect, and can be widely applied to the boiler flue to be used as a dust collecting and desulfurizing device.

Description

Wet type desulfurizing dust collector

Technical field: the invention is the improvement to the desulfurizing dust-collector structure, and the wet type desulfurizing dust collector after the improvement is used in desulfurization and dedusting in the boiler flue.

Background technology: at present, in boiler flue the sedimentation of employed dust arrester dirt particle agglutination relatively poor, negative pressure is moved fan belt water sometimes, influences blower fan service life, cone-shaped dust collecting box liquid level is wayward, flue dust clean-up effect again is relatively poor.

Summary of the invention: the purpose of the invention provides a kind of dedusting, the tangible wet type desulfurizing dust collector of desulfurized effect; The purpose of the invention is achieved through the following technical solutions; Wet type desulfurizing dust collector, comprise cylindrical shell, smoke-intake pipe, pipe, it is characterized in that making the pond body in the bottom, in pond body upper port mounting seat, guider and Venturi tube are installed on the base, making through hole on the base respectively communicates with Venturi tube and guider, cylindrical shell is installed on the body of pond, water knockout drum is installed, and water knockout drum is fixed with Venturi tube and cylindrical shell respectively, and hand-hole and pipe are installed on the cylindrical shell, smoke-intake pipe is installed in the Venturi tube upper end, be installed into water pipe in smoke-intake pipe and Venturi tube, guider is made fan-shaped batter post passage, and water knockout drum is made circular louvre type passage.

The advantage of the invention: owing to adopted water inlet pipe, be adsorbed and be attached in the water when the flue gas of dust-laden enters dust in the flue gas that makes dust-laden under the water droplet collision of Venturi tube and water inlet pipe and the centrifugal action and sulfide at a high speed, remove dust and desulfurization, when air-flow and water are gone out in by Venturi tube, because speed slows down, under gravity and action of inertia, part water is broken away from, fall into the pond, below, the fan-shaped batter post passage of crossing guider when air communication rises when entering cavity process between guider and the water knockout drum, under the guider effect, the air-flow rotation is risen, remaining moisture is thrown on the cylinder inboard wall in the air-flow under the action of the centrifugal, flows into the pond, and this is final dusting and dewaters, after the air-flow that rises enters water knockout drum, because water knockout drum is to make circular blind window passage, water is blocked again, flows into the pond, its advantage is dedusting, desulfurized effect is obvious, moisture-free in the flue gas behind the dust-removal and desulfurizing does not produce corrosion to blower fan, prolongs blower fan service life.

The specific embodiment: wet type desulfurizing dust collector, by pond body 11, cylindrical shell 2, guider 3, Venturi tube 12, base 13, water knockout drum 7, hand-hole 10, smoke-intake pipe 1, pipe 6, water inlet pipe 5 constitutes, body 11 usefulness metal materials in pond are made, also can use cement masonry, constitute the pond, in pond body 11 upper port mounting seat 13, guider 3 and Venturi tube are installed on the base 13, make the through hole that communicates with Venturi tube 12 and guider 3 on the base 13, cylindrical shell 2 is installed on the pond body 11, water knockout drum 7 is installed, water knockout drum 7 is packed in respectively on cylindrical shell 2 and the Venturi tube 12, install with boatswain chair 9 and cylindrical shell 2, install with gripper shoe 8 and Venturi tube 12, hand-hole 10 and pipe 6 are installed on cylindrical shell 2, smoke-intake pipe 1 is installed on the Venturi tube 12 by ring flange 4, water inlet pipe 5 is installed in smoke-intake pipe 1 and the Venturi tube 12, endoporus made by guider and cylindrical is divided into a plurality of fan-shaped through posts and fan-shaped through post is suitable for reading towards a direction inclination, be incorporated into 2,3,4 explanation incline directions, be clockwise direction, water knockout drum is made the circular louvre type structure of umbrella shape, and the blind window opening direction is consistent with the guider incline direction, like this air-flow direction of rotation unanimity of Shang Shenging.

The desulfurization and dedusting working procedure is; When swiftly flowing flue gas enters the water droplet collision that Venturi tube and water inlet pipe enter from smoke-intake pipe, produce the heating power cohesion simultaneously, dust in the flue gas and sulfide are adsorbed to be attached in the water, when flue gas when Venturi tube is gone out, it is big that the space becomes suddenly, flue gas flow rate reduces suddenly, under gravity and action of inertia, part water is broken away from, take away a part of dust and sulfide, fall into the pond, below, when flue gas when guider passes through, guider tilts to make the flue gas rotation to rise, at this moment the part in the remaining moisture in the flue gas is bumped against on the cylinder inboard wall, the water that will contain dust and sulfide touches down the pond, this is final dusting and dewaters, the flue gas that rises continues to rise, remaining moisture blocks and wanders in the pond in the louver that water knockout drum tilts stops flue gas, this is a dust-removal and desulfurizing for the third time, discharges from pipe through the flue gas that water knockout drum flows through, and desulfurized effect is 70～80% in the flue gas of discharge, dust removing effects is up to more than 95%, be not with simultaneously water to discharge in the flue gas, do not corrode blower fan, prolong blower fan service life.
