Description
Technical field
The utility model belongs to the heat-exchange device of the fixed pipe channels assembly that is used for two kinds of heat exchange mediums, particularly a passage is configured in the heat transmission equipment of another the inside.
Background technology
Under the deep mining condition, ground temperature constantly raises, and the heat evil also increases day by day, has a strong impact on the efficient of operating worker and their physical and mental health, even cause the generation of some mine serious accidents probably, brought great threat for the safety in production and the daily management thereof of mine.Mainly by arranging that in the well passage of lane the cool-down dehumidification device reduces temperature,, require the cool-down dehumidification body long-pending little, good effect of heat exchange at present because the tunnel is narrow.But because the coefficient of heat transfer of gas and liquid differs more than 100 times, simultaneously present cool-down dehumidification device mainly improves the whole coefficient of heat transfer of heat exchanger by employing bronzing pipe or transverse finned tube, but effect is not clearly, and volume is still bigger, is difficult for arranging.The bronzing pipe need adopt many snake types to arrange, causes resistance very big, increases the blower fan power consumption.Transverse finned tube is a kind of heat exchange mode of cheapness, but its shortcoming also is a lot, and resistance is big, the coefficient of heat transfer is low, easy dust stratification, easy to clean not.
The utility model content
In order to overcome the deficiency that existing cool-down dehumidification device resistance is big, the coefficient of heat transfer is low, the purpose of this utility model provides a kind of downhole cooling air-cooling dehumidifier, and this downhole cooling air-cooling dehumidifier not only has higher heat exchange efficiency, and fluid resistance is little.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of downhole cooling air-cooling dehumidifier, comprise housing, the heat exchanger tube unit, header tube, feed tube, drain pipe, it is characterized in that: described heat exchanger tube unit is followed successively by interior pipe from inside to outside, outer tube, fin, between interior pipe and the outer tube rectangular support bar is housed, in the outer and inner pipe of outer tube is gas passage, between interior pipe and the outer tube is flow channel for liquids, each rectangular arrayed in heat exchanger tube unit, heat exchanger tube unit and horizontal header tube intersect vertically, and pipe passes header tube in it, header tube communicates with the heat exchanger tube flow channel for liquids, header tube is connected by tube connector with the liquid in-out pipe is vertical mutually, and every row heat exchanger tube unit is equipped with bracing frame.
The termination sealing of described heat exchanger tube unit its pipe when being positioned at liquid in-out pipe column.
Described heat exchanger tube unit outer tube is welded on the header tube wall by the fixing head of heat exchanger tube.
Described support bar is divided into the 3-10 group according to heat exchanger tube length, and every group leader's bar shaped support bar has three strip support bars to be 120 degree angles distributions.
Pipe and outer tube section are circular or oval in described.
Described housing is a frame type, and the housing two ends are that hemispherical dome reducing head is respectively the humid gas import and export, in the humid gas outlet demister are housed, and on the housing peripheral frame luffer boards are housed, and rinse mouth and sewage draining exit are housed on the housing.
The beneficial effects of the utility model are because heat exchanger tube of the present utility model unit is followed successively by interior pipe, outer tube, fin from inside to outside, between interior pipe and the outer tube rectangular support bar is housed, in the outer and inner pipe of outer tube is gas passage, between interior pipe and the outer tube is flow channel for liquids, can increase the heat exchange area of gas flow, thereby the flow velocity that improves water in the flow channel for liquids improves heat exchange efficiency, support bar has positioning function, break the liquid laminar flow simultaneously and form turbulent flow, and strengthened liquid side heat exchange area.Form the gas of big flow and the liquid heat exchange of low discharge, dwindled the coefficient of heat transfer poor of two kinds of different mediums.
Housing is made up of framework and luffer boards in addition, and luffer boards are easy to heat exchanger cleaning dust and internal overhaul.
