Problems solved by technology
[0003] However, due to the complexity of the equipment, the current boiler flue gas purification device, the investment of the flue gas purification device is close to 10% to 15% of the total investment, and the operation technology requirements are high, so that the management cost remains high, and there are very small installations for medium-sized and below-scale boilers. Flue gas cleaning device, even if there is, it is only a low-efficiency impact pool type smoke cleaning device

Embodiment Construction
[0019] refer to Figure 1 to Figure 3 , a gas-liquid film cyclone purification device provided by the present invention, a feed pipe 1 with a tangential inlet is connected to one side of a horizontally placed equal-diameter circular pipe 3, and the feed pipe 1 is a gradually changing rectangular pipe, and its flow path is along the The cross-section of the flow direction is a rectangle with a gradually larger aspect ratio, and a sealing plate 12 is installed at one end of the same side, and the discharge pipe 2 installed concentrically with the equal-diameter circular tube 3 extends into the equal-diameter circular tube 3 from the center of the sealing plate 12, The discharge pipe 2 is a tapered circular pipe whose inner diameter gradually decreases from the inside to the outside. The discharge pipe 2 is connected to a short cone 11 that gradually becomes smaller along the outlet direction on the outside of the sealing plate 12. The diameter of the circular pipe 3 is The other...

A gas-liquid film cyclone purification device, one side of the equal-diameter circular tube placed horizontally is connected with a tangential inlet feed pipe, the same side end is equipped with a sealing plate, and the discharge tube installed concentrically with the equal-diameter circular tube is formed by a sealing plate. The center of the plate extends into the equal-diameter circular tube, and the other end of the equal-diameter circular tube is connected with a conical constriction section. The small end of the conical constriction section is installed with a conical top facing inward. There is an open liquid buffer tank, and a rectangular opening is opened in the middle of the bottom of the equal-diameter circular pipe along the axial direction, and a liquid overflow rectangular joint, a liquid overflow rectangular joint, etc. are installed outside the rectangular opening and at the bottom of the equal-diameter circular pipe. A diversion baffle is installed in the axial direction of the diameter circular pipe to separate the liquid overflow rectangular connection into two chambers, and the diversion baffle extends upward from the rectangular opening into the equal diameter circular pipe to form a protrusion. The invention has the advantages of less occupied area, sensitive and convenient operation and adjustment, and good treatment effect.
Description
technical field [0001] The invention relates to a gas treatment device, specifically a gas liquid film cyclone purification device, belonging to the technical field of environmental protection, which can remove and purify the liquid film neutralization and salt formation of harmful gases containing acid, such as sulfur dioxide gas; And dust, such as coal-fired wood-burning boiler flue gas liquid film adsorption purification containing carbon fine powder, that is, the field of gas purification suitable for general aqueous solution contact. Background technique [0002] Although my country's environmental protection has made positive progress, the environmental situation is still grim. The coal-based energy structure of industries above designated size has resulted in high air pollutant emissions. Regional air pollution problems have become increasingly prominent. The type of acid rain has changed from sulfuric acid to Convert to compound type of sulfuric acid and nitric acid. ...
