specific Embodiment approach 1

[0030] figure 1 It is a structural schematic diagram of a cooling unit connected and installed with the flue pipe 9 and the desulfurization device 10 in a preferred embodiment of the present invention. from figure 1 It can be seen that the cooling unit is a cylindrical double-shell structure, and the two ends are provided with the connection with the smoke pipe 9, and the mechanism 5 (flange). In addition to the connection mechanism 5, the body 1 of the cooling unit has an outer shell 2 and an inner tube 3 inside, and several groups of cooling tubes 4 are arranged radially along the inner tube 3. Each group of cooling pipes 4 is fixedly connected with the inner pipe 3 and the outer shell 2 . The cooling pipe 4 is provided with an inlet and an outlet for the cooling medium to enter and flow out. Adjacent cooling pipes 4 are arranged in a staggered manner by pressing seams to block the high-heat flue gas circulating in the inner pipe, so as to prolong the residence time of th...

specific Embodiment approach 2

[0035] image 3 It is a structural schematic diagram of another preferred embodiment of the present invention. The difference between this embodiment and the first embodiment is that there is still a diversion groove 19 at the bottom of the inner pipe 3, so as to guide the condensed water vapor or the flushing spray liquid.

Abstract

The invention discloses a double-circulation cooling unit for a sintering machine and a cooling device containing the cooling unit, and belongs to the technical field of high-temperature sintering cooling equipment. The double-circulation cooling unit for the sintering machine comprises a machine body, wherein a mechanism for circulating cooling media is arranged in the machine body; the machine body comprises a shell, an inner tube arranged in the shell in a sleeved mode, one or more groups of cooling pipes which are arranged along the radial direction of the inner tube and a connecting mechanism which is positioned at the end part of the machine body; and a channel for circulating the cooling media is arranged between the shell and the inner tube. Meanwhile, the invention further provides the cooling device containing the cooling unit. The cooling unit has the characteristics of being high in cooling rate, convenient to install and the like, and the problem that a large amount of sulfur-containing dust vapor is generated by the sintering machine can be well solved.

Description

technical field [0001] The invention relates to a double-circulation cooling unit for a sintering machine and a cooling device containing the cooling unit, belonging to the technical field of high-temperature sintering cooling equipment. Background technique [0002] The sintering machine is a necessary large-scale equipment in metallurgy and other industrial fields. During the sintering process, a large amount of sulfur-containing waste gas is often generated, which requires further desulfurization treatment. However, the exit temperature of the head of the existing sintering machine is very high, generally between 120-150 degrees, and the high-temperature flue gas entering the desulfurization device will cause excessive water vapor in the desulfurization process, thereby forming a large amount of water containing dust. steam. The discharge of this kind of water vapor will cause serious pollution to the environment, and it is very easy to cause the PM2.5 and other indicato...
