Efficient vacuum water bath dust collector

Abstract

The invention provides a high efficient vacuum water-bath deduster. The deduster comprises a shell, a sedimentation basin, a dust exhaust pipe, a dust exhaust chamber, and a water inlet pipe; the dust exhaust chamber is arranged under the shell, one end of the dust exhaust pipe is connected to the lower end of the dust exhaust chamber, the other end of the dust exhaust pipe is arranged in the sedimentation basin, and the center of the water inlet pipe is provided with a water pump. The deduster is characterized by also comprising a smoke evacuating pipe, a drawing fan, a partition plate, an automatic limiting and water-supplementing mechanism, and a regular slag cleaning machine; the drawing fan is arranged in the center of the smoke evacuating pipe, the partition plate is fixedly arranged in the upper part of the shell center so as to divide the upper part of the shell into a smoke-in chamber and a smoke-out chamber, the automatic limiting and water-supplementing mechanism is arranged on a proper position of the final stage of the sedimentation basin, and the regular slag cleaning machine is arranged on a proper position of the first stage of the sedimentation basin. The dust-containing flue gas is driven by the drawing fan to go through and be washed by the flowing dedusting water medium, and thus the stability of discharge indexes is achieved. The dusts in the sedimentation basin can be regularly removed by the regular slag cleaning machine, and the dedusting water medium can be supplemented by the automatic limiting and water-supplementing mechanism, so the automation degree of the deduster is high.

Description

technical field [0001] The invention relates to a high-efficiency vacuum water bath dust collector. Background technique [0002] At present, the wet dust collectors that use water as the dust removal medium can be roughly divided into spray dust collectors, water film dust collectors and composite dust collectors that combine water film spray. These types of dust collectors are used in practice. In the process of use, there are problems such as incomplete dust removal and excessive exhaust emissions. The reason is that the dusty flue gas cannot fully contact with water. In order to solve the above problems, Chinese patent CN100386133C discloses a water-bath dust collector, which includes a shell, a guide barrel and a rotating barrel installed on it, one end of the smoke guide barrel is inserted into the shell, and the other end is provided with a spiral side inlet. There is a main shaft extension hole at the center of the top of the smoke guide barrel, and the main shaft p...

AI Technical Summary

Problems solved by technology

This water-bath dust collector has the characteristics of high dust removal rate, energy saving, and low noise, but it has the following problems: (1) Since the guide bucket, rotary bucket, and spiral impeller are installed in the housing, it is very difficult to Maintenance; (2) Since the dust removal water medium is stored in the bathroom, with the prolongation of the bath time, the water quality is getting worse and worse, and the dust removal effect is getting worse and worse, which affects the stability of the emission index; (3) When the dust removal When the indoor dust is deposited to a certain extent, it is necessary to manually open the sewage valve to discharge it to the settling tank, which is inconvenient to operate and increases the operating cost; (4) When the dust is discharged, the dust removal water medium is also discharged at the same time , therefore, during this period of time, the dust-laden flue gas cannot be dedusted
