Abstract

The present invention relates to a wet duster for continuously processing sludge water with dust after tail gas airflow of a cement vertical kiln is processed by water film and water fog. The box body of the wet duster is split into two units (or a plurality of units); each unit is also split into two chambers; the sludge water flow slowly in a vertical labyrinth method in the box body; under the action of the gravity, slag deposits in the lower box body and discharged by a scraper conveyer, and clear liquid flows out automatically.

Description

A kind of wet type dust remover for vertical kiln

This deduster is used to handle the sludge water that contains dust after cement in vertical kiln tail gas air-flow passes through moisture film and water smoke processing in environmental engineering, be a kind of novel wet scrubber.

The sludge water that contains dust after cement in vertical kiln tail gas air-flow process moisture film and water smoke are handled is handled, can adopt existing various solid-liquid separating equipments both at home and abroad, as sedimentation basin, thickener, vacuum filter, plate and frame filter press, centrifugal dehydrator and more novel " combined type shaft kiln wet dust collector " (China Patent No. ZL-94226542.4 etc.Though these solid-liquid separating equipments have been produced for many years, all have some problems in using: the floor space that has is big, treating capacity is little; Have except that in-house facility, supporting vavuum pump, expense and energy consumption are big; What have can not continuous operation.More novel " combined type shaft kiln wet dust collector ", be to adopt the self-pressing type cloth bag to carry out Separation of Solid and Liquid, confirm in actual the use, the Separation of Solid and Liquid rate can only reach 80% when cloth bag is intact, in case in every long fifties cloth bags more than a meter broken hole is arranged, the Separation of Solid and Liquid rate just will sharply descend, and change cloth bag and must fifties change simultaneously, and quit work.

Purpose of design of the present invention is a shortcoming of attempting to overcome above-mentioned solid-liquid separating equipment, adopts newly-designed vertical labyrinth to separate and continuously-running duty, thereby a kind of wet scrubber of novel Separation of Solid and Liquid is provided.

Structure of the present invention is provided by following examples and accompanying drawing.

Accompanying drawing is the schematic diagram of the wet type dust remover for vertical kiln of proposition according to the present invention.

Describe structure of the present invention and working condition in detail below in conjunction with accompanying drawing.

During this deduster work, the sludge water that contains dust after cement in vertical kiln tail gas air-flow process moisture film and water smoke are handled, enter in upper box [2] and the lower box [3] by pulp-inlet pipe [1], after sludge water is full of whole box body, will slowly flow along following route: sludge water is entered the top, first Room [5] of the first module [4] of upper box [2] by pulp-inlet pipe [1], flow under the gravity effect in the lower box [6] of first module [4].Because cell separators [7] is divided into first module [4] and Unit second [8] with upper box [2] and lower box [3] partition,, be rushed to the top of second Room [10] of the first module [4] of upper box [2] so sludge water can only be crossed locellus dividing plate [9] from the bottom.Again because the upper height of cell separators [7] is lower than the height of locellus dividing plate [9] and upper box [2] side plate, sludge water can only be crossed the top, first Room [11] of Unit second [8] that cell separators [7] flows to upper box [2], under the gravity effect, flow in the lower box [12] of Unit second [8], cross locellus dividing plate [13] then from the lower part, be rushed to the top of second Room [14] of the upper box [2] of Unit second [8].Because the upper height of cell separators [15] both had been lower than the side plate height of locellus dividing plate [13] and upper box [2], be lower than the height of cell separators [7] again, so sewage can only be crossed cell separators [15], flow through outwards discharging of funnel [16].

When sludge water was slowly mobile along the direction in above-mentioned vertical labyrinth, under the gravity effect, quarrel in the sludge water will sink in lower box [6] the second unit lower boxes [12] of first module.Drag conveyor [17], [18] (also can be conveying worm) of tilting to install is housed respectively in lower box [6] and lower box [12].Scraper plate [19] in drag conveyor [17], [18] is done slowly motion under the drive of motor [20] and reductor [21], blow the heavy quarrel in lower box [6], [12] off discharge respectively.Because quarrel in the sludge water is discharged from, the sewage that flows out from funnel [16] in fact is clear liquid like this.

For sludge water is flowed by giving fixed direction, locellus dividing plate [9], [l3] upper and lower height are consistent with upper box [2] upper and lower height, cell separators [7], [15] upper height will be lower than the upper height of upper box [2], and the height of cell separators [15] will be lower than the unit every the height of [7] (multiple-unit in this way, the cell separators height will reduce in proper order), cell separators [7], [15] bottom will be divided into lower box [3] two parts of partition: the first module lower box [6] and the second unit lower box [12].

This deduster upper box [2] and lower box [3] can be divided into two unit.For the sludge water Separation of Solid and Liquid is got better, upper box [2] and lower box [3] also can be divided into the above multiple-unit in Unit two.

Wet scrubber of the present invention has the following advantages:

1, deduster is made up of upper and lower casing and drag conveyor, and structure is very simple.

2, deduster box height, width and length can change on demand, and floor space is little, and installation adaptability is strong.

3, moving component is few, the equipment dependability height, and maintenance capacity is little.Scraper plate is made low-speed motion, and motor power (output) is little, and energy consumption is low.

4, sludge water is made vertical labyrinth mode and is flowed in casing, and the sub-sedimentation route of quarrel is long in the sludge water, helps Separation of Solid and Liquid, Separation of Solid and Liquid rate height.

But 5 continuous operations.
