Abstract
The utility model discloses a horizontal dry boiler tail gas heat exchanger mainly includes from the right side to left intake pipe, heat exchanger shell and the blast pipe that connects gradually, its characterized in that heat exchanger shell is the cuboid shape, and rather than the water tank side board formation confined water tank body of the left and right sides, water tank body top is equipped with the water inlet, and the below is equipped with the delivery port, sets up a plurality of root circle cylindricality heat transfer flue gas pipes between the water tank side board, and the breast hole is still left respectively to intake pipe and blast pipe opening in heat transfer flue gas pipe both ends below the blast pipe. The utility model discloses a heat exchanger adopts reverse -flow heat exchange, and heat recovery is efficient, and structural design is simple reasonable, practical easy the popularization.
Description
Technical field
The utility model belongs to calcium carbonate production and processing field, specifically relates to a kind of horizontal dry boiler tail gas heat exchanger.
Background technology
In calcium carbonate production process, when carbonic acid calcium carbonate slurry is dry, use dry boiler, the flue gas that dry boiler produces in combustion, temperature is high, and the boiler exhaust gas of discharge, as direct discharge, will impact environment, 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 horizontal dry boiler tail gas heat exchanger, to the heat energy recycle of high-temperature flue gas.
The utility model realizes like this, horizontal dry boiler tail gas heat exchanger, mainly comprise the air inlet pipe, outer cover of heat exchanger and the blast pipe that connect successively from right to left, it is characterized in that outer cover of heat exchanger is rectangular shape, closed water tank is formed with the water tank side board of its left and right sides, water inlet is provided with above water tank, below is provided with delivery port, some cylindrical heat exchange fume pipes are set between water tank side board, breast hole, respectively to air inlet pipe and blast pipe opening, is also left below blast pipe in heat exchange fume pipe two ends.
Its main operation principle adopts the cooling water in boiler exhaust gas and water tank to carry out reverse-flow heat exchange, boiler exhaust gas enters from air inlet pipe, through transcalent heat exchange fume pipe, complete heat exchange by the cooling water of reverse flow in heat exchange fume pipe outer wall and water tank, finally discharged by the exhaust outlet of blast pipe.
The beneficial effects of the utility model are: 1, this structure adopts reverse-flow heat exchange, and energy recovery efficiency is high; 2, structural design advantages of simple, practicality is easily promoted.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the lateral plan at water tank side board place.
In the drawings, 1, shell 2, air inlet pipe 3, blast pipe 4, water tank side board 5, heat exchange fume pipe 6, water inlet 7, delivery port 8, breast hole.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, horizontal dry boiler tail gas heat exchanger, mainly comprise the air inlet pipe (2) connected successively from right to left, outer cover of heat exchanger (1) and blast pipe (3), it is characterized in that outer cover of heat exchanger (1) is rectangular shape, the water tank closed is formed with the water tank side board (4) of its left and right sides, water inlet (6) is provided with above water tank, below is provided with delivery port (7), some cylindrical heat exchange fume pipes (5) are set between water tank side board (4), heat exchange fume pipe (5) two ends are respectively to air inlet pipe (2) and blast pipe (3) opening, breast hole (8) is also left in blast pipe (3) below.
During work, at water inlet (6) and delivery port (7) connecting water pipe of water tank, water is allowed to flow in water tank, it flows to is from left to right, boiler exhaust gas enters from air inlet pipe (2), when transcalent heat exchange fume pipe (5) is flowed from right to left, reverse-flow heat exchange is completed by the cooling water of reverse flow in heat exchange fume pipe (5) outer wall and water tank, flue gas enters blast pipe (3) again through heat exchange fume pipe (5), discharged by exhaust outlet, breast hole (8) keeps closing, after heat exchange completes, regularly from breast hole (8) dust out and dregs, in order to avoid blocking heat exchange fume pipe (5).
Claims (1)
