The purpose of this utility model is that a kind of thermal efficiency height will be provided, and can make up as required and easy accessibility, easily repairs and hot-blast stove durable, energy savings.
The technical solution of the utility model is: but the body of heater that should replace tubes combined hot-blast stove has the air outlet (2) on secondary combustion chamber (14), fire seperating board (13), flue gas chamber (12) and the outer sleeve (4) on fire grate (17), top of the interior burner hearth (16) of air passageway (15), the inner sleeve (1) formed by inner sleeve (1) and outer sleeve (4), burner hearth (16) bottom to form; Its characteristics are that some groups of bobbin carriage unit (5) are arranged on the top of body of heater, there is a square shell (22) bobbin carriage unit (5), there are two tube sheets (23a, 23b) to be divided into three cavitys in the shell in the shell (22), its two ends cavity is air duct (25a, 25b), and middle cavity promptly is equipped with some groups of heat exchanger tubes (24) between two tube sheets (23a, 23b); The top of shell (22) and two tube sheets (23a, 23b) all has groove (27); At one end a diaphragm plate (26) is equipped with on the tube sheet (23a) of air duct (25a) and the top between shell (22); End air duct (25) in one group of bobbin carriage unit of topmost locates to be connected to a blast pipe (6), and the top of this group bobbin carriage unit connects a collection smoke box (11), and this collection smoke box (11) is connected with chimney (9).
But be somebody's turn to do the replace tubes combined hot-blast stove, be characterized in being welded with pipeloop (31) on the tube sheet (23) in the bobbin carriage unit (5), heat exchanger tube (24) is plugged between the pipeloop (31) on the two ends tube sheet (23), fills with asbestos packing (32) between heat exchanger tube (24) and pipeloop (31).
But be somebody's turn to do the replace tubes combined hot-blast stove, be characterized in the interlaced arrangement of each heat exchanger tube (24), the rhombus each other of looking from its cross section.
But be somebody's turn to do the replace tubes combined hot-blast stove, its characteristics are in air intake one side of heat exchanger tube (24) deflector (30) to be housed.
But be somebody's turn to do the replace tubes combined hot-blast stove, be characterized in that the both sides of the air duct (25a, 25b) in bobbin carriage unit (5) have observation window (28), cover plate (29) is housed respectively on the observation window (28).
But be somebody's turn to do replace tubes combined type wind-heat stove; be characterized in being equipped with protective relaying device; this device is: be connected a wireway (8) between air inlet (6) and chimney (9), adorn a normally closed solenoid valve (7) in wireway (8), adorn a normally open solenoid valve (10) in the chimney.
The utility model has following effect and advantage: 1, thermal efficiency height: owing to adopt horizontal wind pipe type, flue gas flows the heat exchanger tube intercropping S of stagger arrangement shape, has increased flow process, the heat exchange area of increase, thereby improved the thermal efficiency; 2, combination, dismounting, replace tubes are all very convenient, and institute is so that maintenance; 3, smoke medicining dust-removing effect is good, and flue gas flows the heat exchanger tube intercropping S of stagger arrangement shape, and the dust in the flue gas is very easily assembled sinking, and heat exchange can not stopped up.
