Description

Lime burner furnace flue gas heat-exchange unit
Technical field
The utility model belongs to calcium carbonate manufacture field, specifically relates to a kind of lime burner furnace flue gas heat-exchange unit.
Background technology
The flue gas that lime burner furnace produces in calcination process, temperature is high, and the flue gas of discharge is as discharged after the detoxication directly entering waste gas, and high temperature can increase difficulty to exhaust-gas treatment, also causes the waste of heat energy simultaneously.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of lime burner furnace flue gas heat-exchange unit, to the heat energy recycle of high-temperature flue gas.
The utility model realizes like this, lime burner furnace flue gas heat-exchange unit, mainly comprise the air inlet pipe, water tank and the escape pipe that connect from top to bottom, it is characterized in that air inlet pipe, water tank and escape pipe are structure as a whole, described water tank is cylindrical hermetic body structure, be provided with water inlet below water tank sidewall, arrange by delivery port above sidewall, some cylindrical heat exchange fume pipes are set in water tank; Heat exchange fume pipe two ends are respectively to air inlet pipe and escape pipe opening; Leave dust removal port below escape pipe, sidewall upper shed is exhaust outlet.
Its main operation principle adopts flue gas and cooling water to carry out reverse-flow heat exchange, the flue gas that lime burner furnace produces in calcination process enters from air inlet pipe, through transcalent heat exchange fume pipe, heat exchange is completed by the cooling water of reverse flow in heat exchange fume pipe outer wall and water tank, flue gas enters escape pipe again through fume pipe, is discharged by exhaust outlet.
The beneficial effects of the utility model are: 1, this structure can complete reverse-flow heat exchange, and energy recovery efficiency is high; 2, reasonable in design, equipment realizes being simple and easy to promote the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A view of the present utility model.
In the drawings, 1, air inlet pipe 2, water tank 3, escape pipe 4, heat exchange fume pipe 5, water inlet 6, delivery port 7, exhaust outlet 8, dust removal port.
Detailed description of the invention
As shown in Figure 1 and Figure 2, lime burner furnace flue gas heat-exchange unit, mainly comprise the air inlet pipe (1), water tank (2) and the escape pipe (3) that connect from top to bottom, it is characterized in that air inlet pipe (1), water tank (2) and escape pipe (3) are structure as a whole, described water tank (2) is cylindrical hermetic body structure, be provided with water inlet (5) below water tank (2) sidewall, arrange by delivery port (6) above sidewall, cylindrical heat exchange fume pipe (4) is set in water tank (2); Heat exchange fume pipe (4) two ends are respectively to air inlet pipe (1) and escape pipe (3) opening; Dust removal port (8) is left in escape pipe (3) below, and sidewall upper shed is exhaust outlet (7).
During work, at water inlet (5) and delivery port (6) connecting water pipe of water tank (2), allow it according to dotted arrow direction flowing in Fig. 1, the flue gas that lime burner furnace produces in calcination process enters from air inlet pipe (1), when transcalent heat exchange fume pipe (4), heat exchange is completed by the cooling water of reverse flow in heat exchange fume pipe (4) outer wall and water tank (2), flue gas enters escape pipe (3) again through heat exchange fume pipe (4), discharged by exhaust outlet (7), in Fig. 1, solid arrow direction is flue gas flow direction.
