Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 Shown is a dust removal pipeline spark elimination device, which includes a variable diameter tube 5 installed in the middle of two sections of dust removal pipelines through flanges 1 at both ends. A fire arresting net 2 is installed on one side of the reducing pipe 5, and two sets of spark arresting plates 3 are installed in the inner cavity of the reducing tube 5, and each set of spark arresting plates 3 is composed of several plates 7 parallel to each other, and the plates 7 The angle with the horizontal plane is 25-45°. The bottom wall of the reducing pipe 5 is provided with an ash discharge port 4 .

[0018] Asbestos rubber gasket 6 is installed at the joint of flange 1 .

[0019] The size of the holes on the fire arresting net 2 and the thickness of the material woven into the fire arresting net 2 are designed according to th...

Abstract

The invention discloses a spark eliminator for dust collection pipelines, comprising a reducing pipe having two ends mounted in the middle of two dust collection pipelines through flanges; the inner diameter of a middle cavity of the reducing pipe is greater than that of the dust collection pipelines, one side of each flange is provided with a fire retardant mesh, two groups of spark trap plates are mounted in the inner cavity of the reducing pipe, and each group of spark trap plates includes a plurality of parallel plates which are 25-45 degrees angled to the horizontal plane. Spark particles are decomposed twice and refined by using the fire retardant meshes, running speed of the spark particles is decreased through the increase in the inner diameter of the reducing pipe, the running direction and speed of the spark particles are changed through the spark trap plates, impact and burn of filter bags of bag dust collectors due to the spark particles are eliminated, and the service lives of the filter bags are effectively prolonged. The spark eliminator is simple and compact in structure, convenient to manufacture and mount, low in production cost and widely applicable to various dust collectors.

Description

technical field [0001] The technical field of design dust removal equipment of the present invention is specifically a spark elimination device for dust removal pipelines. Background technique [0002] In the dust removal pipelines of steelmaking electric furnaces, ferrosilicon furnaces, brick kilns and other industrial kilns, due to the large air volume of the dust collection outlet, some large spark particles in the kiln are often sucked into the pipeline. The filter bags in the bag filter cause impact and burns, which affect the filtering effect of the filter. The traditional method is to install a cyclone dust collector between the pipeline and the bag filter to eliminate the sparks in the flue gas. However, the cyclone dust collector is bulky, consumes a lot of steel, and has high manufacturing costs. For some small kilns, the investment in the dust removal system will be too high, which will increase the investment cost of users. Contents of the invention [0003] T...
