Abstract

The invention discloses a blowing device for a dry-type calcium spraying flue gas desulfurization system, which comprises a fixed bracket connected to a cylindrical tube, one end of the cylindrical tube connected to a conical tube, and the tail of the conical tube is arranged There is a fan, a feed inlet is provided on the wall of the conical cylinder, and a plurality of horizontal deflectors and a plurality of longitudinal deflectors are arranged in the cylindrical cylinder, and the horizontal deflectors and the longitudinal deflectors are connected with a pair of The pull rods are movably connected, and the pull rods are controlled by a motor to expand and contract, and a pair of flaps are provided at the end of the cylindrical tube to open and close. The blowing device for the dry-type calcium spraying flue gas desulfurization system of the present invention is provided with a cylindrical tube on the body, and a group of longitudinal deflectors and a group of transverse deflectors are arranged in the cylindrical tube, and the longitudinal deflectors and The horizontal deflector is used to guide the flow direction of the fluid in the cylindrical barrel, which has a better control and adjustment effect on the fluid, which is beneficial to control the stability of the fluid and improve the injection efficiency.

Description

technical field [0001] The invention relates to an injection device for a dry calcium injection flue gas desulfurization system. Background technique [0002] The dry calcium spraying flue gas desulfurization system is mainly suitable for desulfurization of small and medium-sized boilers in coal-fired power plants. The main task of the system is to complete material transportation, metering, powder feeding amount adjustment, and furnace injection, so that the limestone powder is calcined and decomposed in the furnace, and the generated Cao is used to react with So2 in the flue gas in the furnace to achieve desulfurization in the furnace. . The system has the advantages of simple configuration, low energy consumption, no pollution, high degree of automation, low investment, and high desulfurization efficiency. The injection device is an important part of the dry calcium injection flue gas desulfurization system, but the injection direction of the commonly used injection d...
