Abstract
The utility model discloses a biomass gas tube type heat exchanger. The biomass gas tube type heat exchanger is formed by connecting a preheating section and a heat exchange section, wherein tubes are arranged in the preheating section, and tubes are arranged in the heat exchange section. The upper end of the preheating section is connected with an air inlet cavity, an air inlet and an air outlet are formed in the sides of the preheating section, the lower end of the heat exchange section is connected with an air outlet cavity, and a circulation air inlet and a circulation air outlet are formed in the sides of the heat exchange section. A heat exchanger body is designed into the two sections, the temperature of high-temperature waste heat smoke is reduced to about 600 DEG C at the preheating section through heat exchange with air, then the smoke moves downwards to the heat exchange section, heat exchange is performed between the smoke and circulation air, therefore, the heat exchanger can complete heat exchange at the high-temperature condition, the service life of the heat exchanger is prolonged, heat of the waste heat smoke is fully used for heating the air and the circulating air, and the purpose of heat energy recycling is achieved.
Description
Technical field
The utility model belongs to technical field of heat exchange, specifically relates to a kind of heat exchanger of living beings waste heat flue gas with heating biomass circulating gas that reclaim.
Background technology
Tubular heat exchanger is important chemical industry equipment, and it is mainly made up of shell, heat exchanger tube etc.With respect to plate type heat exchanger, tubular heat exchanger is for dust-laden, relatively good containing the gas adaptability of drop.But in the time being applied to biological fuel gas heat exchange, because the temperature of living beings waste heat flue gas is up to 800 ℃, tubulation parts are difficult to bear is so working under hot environment, and the life-span is shorter.
Utility model content
The problem existing in order to solve prior art, the utility model provides a kind of resistant to elevated temperatures tubular heat exchanger.
In order to realize above object, the technical solution of the utility model is as follows: biogas tubular heat exchanger, be formed by connecting with the heat exchanging segment that is built-in with tubulation by the preheating section that is built-in with tubulation, the upper end of described preheating section connects inlet chamber, its sidepiece is provided with air intlet and air outlet slit, the lower end of described heat exchanging segment connects outlet chamber, and its sidepiece arranges circulating air import and circulating air outlet.
Compared with prior art, the utility model is due to heat exchanger body design is become to two sections, high-temperature residual heat flue gas first at preheating section by being reduced to behind 600 ℃ of left and right with air heat exchange, allow again flue gas continue to go downwards to heat exchanging segment and circulating air heat exchange, make heat exchanger can under hot conditions, complete heat exchange work, increase the service life, and the heat that takes full advantage of waste heat flue gas adds hot-air and two kinds of gases of circulating air, reach the object of recycling heat energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of tubular heat exchanger
The specific embodiment
As shown in Figure 1, tubular heat exchanger is uprightly placed on the whole, is made up of the inlet chamber 2 arranging from top to bottom, preheating section 2, heat exchanging segment 1, outlet chamber 4.The enclosure of preheating section arranges tubulation, and its upper end connects inlet chamber, and shell sidepiece arranges air intlet and air outlet slit.The enclosure of air inlet section arranges tubulation, and its lower end connects outlet chamber, and shell sidepiece arranges circulating air import and circulating air outlet.
The workflow of biogas tubular heat exchanger is as follows: reclaim 800 ℃ of left and right waste heat flue gases and entered by inlet chamber, along the tubulation of preheating section inside toward current downflow, then along the tubulation of heat exchanger inside toward current downflow, enter after outlet chamber, ash content and unburnt charcoal fall down under Action of Gravity Field, and clean waste heat flue gas is discharged from outlet chamber.When flow of flue gas, by the air intlet input normal temperature air of preheating section upwards flow with tubulation in flue gas heat exchange produce hot-air and export from air outlet slit, and simultaneously, by circulating air import 50 ℃ of left and right circulating air of input (not condensable combustion gas) of heat exchanger, upwards flow with tubulation in flue gas heat exchange produce thermal cycle gas, by circulating air outlet output.By a series of heat exchanging process, 450 ℃ of left and right hot-airs of preheating section output, 300 ℃ of left and right high temperature circulation gas of heat exchanger output, outlet chamber is discharged 150 ℃ of left and right low-temperature flue gas.
Claims (1)
1. a biogas tubular heat exchanger, it is characterized in that: be formed by connecting with the heat exchanging segment that is built-in with tubulation by the preheating section that is built-in with tubulation, the upper end of described preheating section connects inlet chamber, its sidepiece is provided with air intlet and air outlet slit, the lower end of described heat exchanging segment connects outlet chamber, and its sidepiece arranges circulating air import and circulating air outlet.
