Embodiment 1

[0010] Embodiment one sees figure 1 , the upper section of the double-feeding cylindrical warehouse is cylindrical 1, the lower section is conical 2, the upper and lower sections are connected as one, and the bottom is opened with a discharge port, and the bottom of the conical section at the lower part of the cylindrical warehouse is connected to the pants-shaped double-feeding section 3 ,Such as figure 2 As shown, the upper part of the underpants-shaped double-cut section is cylindrical, and two small cones 4 are connected at the bottom of the cylinder. There are discharge ports 5 at the bottom of the two small cones, respectively, and the bottom of the discharge port is connected to the discharge port 5. The material pipeline 6 is provided with a flashboard shut-off door 7, an electric air locker 8, and a screw feeder 9 on the discharge pipeline.

[0011] In this example, the diameter of the steel circular silo is 9500mm, V=710m 3 The limestone powder silo is equipped wi...

Embodiment 2

[0012] Embodiment 2, on the discharge pipeline below the discharge port of the double-feeding barrel-shaped silo, the ram shut-off door and the electric air locker are arranged in sequence. The model of the electric air lock can be selected as 300×300 output 60t / h, and the groove width is 200.

Embodiment 3

[0013] Embodiment 3, on the discharge pipeline below the discharge port of the double-feeding barrel-shaped silo, the ram shut-off door and the electric screw feeder are arranged in sequence. The model of two screw feeders with frequency conversion speed regulation function can be selected as LS400 output 70t / h.

Abstract

The double-discharge port silo has upper cylindrical section, lower conic section and branched bottom section with two discharge ports. Each of the two discharge ports has upper cylindrical section, lower conic section and discharge port in the bottom connected to below discharge pipe, in which there are gate valve, electric gas lock and spiral feeder. The double-discharge port silo with two discharge ports may be used flexibly in high reliability and its two discharge ports may be used simultaneously or with one as spare part. The present invention may be used widely for bulk material storing and transportation in metallurgical, building material, chemical other industry.

Description

(1) Technical field [0001] The invention relates to a storage and delivery device for solid bulk materials, in particular to a storage and delivery device for limestone powder in the flue gas desulfurization process of a thermal power plant. (2) Background technology [0002] In the flue gas desulfurization process of thermal power plants, power plants and industrial boilers usually use fossil fuels. Since these fossil fuels will produce harmful substances such as sulfur dioxide during the combustion process, limestone slurry needs to be used as an absorbent to absorb sulfur dioxide in the flue gas . In the prior art, the limestone powder used to prepare the limestone slurry is stored and transported in a cylindrical silo, and usually the cylindrical silo is used to store the absorbent consumption of the power plant for about a week. The existing silo is in the shape of a cylinder, and there is only one set of discharge pipe system below. Since the production of thermal po...
