The utility model relates to a honeycomb tube wet-type electrostatic precipitator, which comprises an upper air chamber and a lower air chamber, a shell is installed between the upper air chamber and the lower air chamber, and a dust collection module is installed in the shell, and the dust collection module adopts a common-wall honeycomb A discharge system is installed between the dust collection module and the upper air chamber; a flushing system is installed in the upper air chamber, a hot air insulation system is installed outside the upper air chamber, an air distribution device is installed in the lower air chamber, and the flushing system is located in the dust collection module Directly above, the air distribution device is located directly below the dust collection module. The utility model adopts a common-wall dust collection module, which can make full use of the inner and outer surfaces of the honeycomb tube as the dust collection surface, reduces the size of the dust collection module, thereby reducing the occupied area, and can fully adapt to the tight layout of post-furnace pollution control equipment in active coal-fired power plants Case. The utility model uses conductive and corrosion-resistant materials as the dust collection module, without continuous flushing, so the concentration of water mist at the outlet of the dust collector is extremely low.
Description
Technical field
The utility model relates to the cleaner in a kind of dedusting industry, especially relates to a kind of honeycomb duct wet electrical dust precipitator.
Background technology
Existing wet electrical dust precipitator mainly adopts stainless steel flat plate pole plate, there is the shortcomings such as floor space is large, stainless steel material cost is high, system composition is complicated, operation maintenance requirement is high, wet-esp outlet water smoke concentration is high.Therefore, the utility model is proposed.
Utility model content
For prior art Problems existing, the purpose of this utility model be to provide a kind ofly to take up an area less, technique is simple, efficiency of dust collection is high, water smoke concentration of emission is low honeycomb duct wet electrical dust precipitator.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of honeycomb duct wet electrical dust precipitator, comprise upper chamber and lower chamber, between described upper chamber and lower chamber, shell is installed, in described shell, module of gathering dust is installed, described module of gathering dust adopts altogether wall honeycomb duct, and gathers dust between module and upper chamber and be provided with discharge system; Be provided with rinse-system in described upper chamber, be provided with hot blast insulation system outside upper chamber, be provided with airflow distribution device in described lower chamber, described rinse-system is positioned at directly over module of gathering dust, and described airflow distribution device is positioned at immediately below module of gathering dust.
Described module of gathering dust is provided with earthing or grounding means.

Described wall honeycomb duct is altogether conductive corrosion-resistant material wall honeycomb duct altogether.
The beneficial effects of the utility model are as follows:
Honeycomb duct wet electrical dust precipitator of the present utility model, adopt the module of gathering dust of wall altogether, the surfaces externally and internally of honeycomb duct can be made full use of as the face of gathering dust, reduce module size of gathering dust, thus minimizing floor space, fully can adapt to the situation of active service Coal Fired Power Plant after stain abatement equipment layout anxiety.The utility model adopts conductive corrosion-resistant material as module of gathering dust, and without the need to continuous flushing, therefore house outlet water smoke concentration is extremely low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-lower chamber; 2-airflow distribution device; 3-shell; 4-gathers dust module; 5-discharge system; 6-upper chamber; 7-rinse-system; 8-hot blast insulation system.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further described, but protection domain of the present utility model is not limited to this.
As shown in Figure 1, honeycomb duct wet electrical dust precipitator of the present utility model, comprises upper chamber 6 and lower chamber 1, shell 3 is installed between upper chamber 6 and lower chamber 1, be provided with module 4 of gathering dust in shell 3, module of gathering dust 4 adopts wall honeycomb duct altogether, and module size can be arranged arbitrarily.And gather dust between module 4 and upper chamber 6 discharge system 5 is installed; Rinse-system 7 is installed in upper chamber 6, hot blast insulation system 8 is installed outside upper chamber 6, in lower chamber 1, airflow distribution device is installed, flue gas can be made evenly to enter module 4 of gathering dust; Rinse-system 7 is positioned at directly over module 4 of gathering dust, and airflow distribution device 2 is positioned at immediately below module 4 of gathering dust.
Module 4 of gathering dust in the utility model is provided with earthing or grounding means, guarantees that system stability is reliable.
The bottom of the discharge system 5 in the utility model is provided with fixing stopping means, guarantees that heteropole is apart from tolerance band.
Hot blast insulation system 8 in the utility model can heat cool ambient air to design temperature, guarantees discharge system stable operation.
Common wall honeycomb duct in the utility model is conductive corrosion-resistant material altogether wall honeycomb duct, can resist SO after wet desulphurization
3corrosion, extend wet electrical dust precipitator service life.
During use, flue gas enters deduster from lower chamber 1, after airflow distribution device 2 water conservancy diversion, evenly enter module 4 of gathering dust.When flue gas flows through and gathers dust module 4, because discharge system 5 continuous discharge produces corona, the dust in flue gas and other pollutant can enclose electric charge, mobile to surface of gathering dust under the effect of electric field force, separate from flue gas.Clean flue gas after process enters downstream flue from upper chamber 6.Rinse-system 7 is at the appointed time interior to be opened automatically, rinses gather dust module 4 and discharge system 5, the dust collected and pollutant is rinsed and discharges to lower chamber.Hot blast insulation system 8 continues the insulated case part purging discharge system, prevents wet flue gas from entering insulated case, causes insulator creepage.
The utility model have compact conformation, floor space few, be easy to the feature safeguarded, dedusting demisting efficiency is high.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
