Embodiment Construction

[0013] Below in conjunction with accompanying drawing and specific example the present invention will be further described:

[0014] Here, the V-shaped splitter plate combined with the orifice plate is used to adjust the airflow of the electrostatic precipitator into the mask, so as to achieve the purpose of optimizing the airflow distribution in the dust collection area. The three-dimensional airflow distribution in the electrostatic precipitator is calculated by using the numerical simulation method, and the method of adjusting the airflow distribution by using the porous plate alone and the combination of the porous plate and the V-shaped shunt in the electrostatic precipitator project is compared, and a V-shaped air flow is proposed. The advantages of splitters in regulating the airflow of electrostatic precipitators.

[0015] The device includes an air inlet splitter main pipe, a splitter plate, and an air inlet manual regulating valve. The role of the splitter plate at ...

Abstract

The invention relates to an electric-bag composite dust removal smoke distribution device which is applicable to a traditional electrostatic dust collector and an existing electric-bag composite-type smoke distribution process. According to the technical scheme, the smoke distribution device in an electric dust removal air inlet hood comprises a dust collector, wherein an ash bucket opening insertion plate and a flap valve are arranged below the dust collector, and the smoke distribution device is characterized by also comprising an air inlet distribution main pipe, a plurality of distribution plates and a manual air inlet adjusting valve, wherein the manual air inlet adjusting valve is installed on the air inlet distribution main pipe. The air speed in a pipeline at each smoke flow route of the dust collector is optimized in a segmentation manner, the air admission of the dust collector adopts an air distribution system and adequately utilizes the natural distribution principle of the air, so that the uniformity and smoothness in air admission of the unit can be guaranteed, and the utilization rate of a filter area can be increased.

Description

technical field [0001] The invention relates to a set of electric bag composite dust removal flue gas diversion device, which is suitable for old electrostatic precipitator and existing electric bag composite flue gas diversion process. Background technique [0002] The air distribution in the electrostatic precipitator is one of the main factors affecting its dust removal efficiency. In order to improve the dust removal efficiency of the electrostatic precipitator, scholars and engineers at home and abroad have done a lot of research on how to adjust the airflow distribution in the precipitator by means of experiments and computer simulations. Whether it is the uniform airflow method mentioned earlier or the oblique airflow theory mentioned in recent years, the method of using a porous plate to regulate the airflow in the electrostatic precipitator is mentioned. However, for some electrostatic precipitators and their design requirements, the simple use of orifice plates to...
