Multi-tube type cooling and aggregating device achieving automatic descaling

Abstract

The invention relates to a multi-tube type cooling and aggregating device achieving automatic descaling. The device comprises a cooler which is provided with a lower air inlet cavity and an upper airoutlet cavity, multiple cooling tubes are connected between the lower air inlet cavity and the upper air outlet cavity, cooling fans are arranged at one side of the cooling tubes, an air distributiontube is arranged in the lower air inlet cavity, exhaust branch rubes with the same number as that of the cooling tubes are arranged on the air distribution tube by cooperating with the cooling tubes and connected with the cooling tubes through Venturi tubes, helical blades are arranged in the cooling tubes and connected with driving motors, an ash bucket is arranged at the lower end of the lower air inlet cavity, a cyclone separating device is connected to the upper air outlet cavity, a coagulant storage bucket with a coagulant supplementing tube is connected to the lower end of the cyclone separating device, the coagulant storage bucket is connected with a feed tank through a quantitative feeding mechanism, and the feed tank is connected with jet orifices of the Venturi tubes through a feed tube. According to the multi-tube type cooling and aggregating device achieving automatic descaling, PM2.5 pollution can be effectively eliminated, dust and dirt in the cooling tube are automatically cleaned away, and system operation is stable and reliable.

Description

technical field [0001] The invention relates to a flue gas treatment device, in particular to a multi-tube cooling and agglomeration device capable of automatic descaling. Background technique [0002] The current flue gas treatment is mainly dust removal, desulfurization, denitrification, dioxin removal, and heavy metal removal, while the current bag dust removal method, dry electrostatic precipitator method, and wet electrostatic precipitator technology mainly remove relatively large particles of dust. Mainly, it is difficult to capture and remove PM2.5 ultra-fine particles that cause smog (such as fine particles with a particle size of ≤1 μm, hard to charge, and non-wetting particles). Therefore, in order to effectively control the occurrence of smog, it is necessary to make great efforts to develop new technology and equipment to remove PM2.5 ultrafine particles (such as particle size ≤ 1 μm, difficult to charge, non-wetting and other fine particles) in the flue gas.
