Centrifugal subsidence mixed dirt remover

Abstract

The invention relates to a dirt separator, in particular to a centrifugal sedimentation composite type dirt separator, which aims at solving the problems of low dirt removing efficiency and difficult granular impurities removing of the prior dirt separator. The dirt separator adopts the structure that an inner cylinder is arranged in an outer cylinder and is coaxial with the outer cylinder, and the upper end of the inner cylinder is fixedly connected with the inner wall of a top cover of the outer cylinder; the wall of the inner cylinder is provided with a through hole, the inner space of the inner cylinder is a rotational flow region, the space between the inner cylinder and the outer cylinder is a sedimentation region, and one end of a water feeding pipe is connected to the lateral wall of the upper end of the inner cylinder and communicated with the rotational flow region inside the inner cylinder. The invention separates a whole flow field into the rotational flow region inside the inner cylinder and the sedimentation region positioned between the inner cylinder and the outer cylinder, a fluid entering the inner part of the dirt separator is rotationally separated and then enters the sedimentation region through the through hole positioned on the wall of the inner cylinder from the rotational flow region, and solid impurities with small grain diameters ranging from 0.075 mm to 1 mm enter the sedimentation region and are separated by low-speed sedimentation.

Description

technical field [0001] The invention relates to a decontamination device. Background technique [0002] The impurities in the water of the heating pipe network are mainly the molding sand used in the casting process of the radiator in the cast iron radiator. The molding sand of the cast iron radiator falls off and enters the pipe network during the operation of the pipe network. Since it is not effectively removed in the decontamination device, it is brought into the In the boiler and deposited on the tube wall of the boiler, it will cause uneven heating of the boiler and even cause the boiler tube to burst. Therefore, removing impurities in the pipe network is very necessary for the safe and economical operation of the boiler. In order to solve the above problems, the Chinese patent application number is 90221371.7, the announcement number is CN2096419U, the announcement date is February 19, 1992, and the utility model patent application named "cyclone decontamination devic...
