Abstract
The utility model discloses a hot -blast furnace with labyrinth separates burning hot tuber pipe. Including furnace body (1), furnace body (1) menstruation heat tuber pipe (2) are connected with the section of thick bamboo (3) of drying, the inner wall of furnace body (1) on be equipped with insulating layer (4), the cavity between insulating layer (4) is combustion chamber (9), hot -blast main (2) inner wall on the symmetric distribution have a fireproof plate (5), a fireproof plate (5) other be equipped with the 2nd fireproof plate (6), a fireproof plate (5) and the 2nd fireproof plate (6) all be tile form. The utility model has the characteristics of isolated flame avoids flame to make the material dissolve, avoids avoiding corrosion of equipment and avoiding furnace end stove tail excessive temperature differentials to improve product quality and production efficiency on the material coheres equipment.
Description
Technical field
The utility model relates to a kind of hot-blast stove of chemical fertilizer production, particularly a kind of hot-blast stove with labyrinth type fire insulation warm-air pipe.
Background technology
Hot-blast stove is by the device of blast heating to required temperature, and its advantage is that heat-exchange temperature is high, and heat utilization efficiency is high, is widely used in the preparation of chemical products and medicine and dry field.But there is following shortcoming in the application in hot-blast stove at present, after hot-blast stove is temperature required to Drying by air heat in combustion chamber, flame in combustion chamber can enter into Drying together along with hot-air (hot blast), this flame can by chemical fertilizer production material melting, equipment is cohered, time has been grown and can cause heavy corrosion to feed opening, causes burner stove tail excessive temperature differentials, affects production quality and the production efficiency of product.
Summary of the invention
The purpose of this utility model is, provides a kind of hot-blast stove with labyrinth type fire insulation warm-air pipe.The utility model has isolated flame, avoids flame that material is dissolved, and avoids material to stick on equipment, avoids equipment corrosion and avoids burner stove tail excessive temperature differentials to improve the feature of product quality and production efficiency.
The technical solution of the utility model: a kind of hot-blast stove with labyrinth type fire insulation warm-air pipe, comprise body of heater, body of heater is connected with Drying through warm-air pipe; The inwall of described body of heater is provided with insulating barrier, and the cavity between insulating barrier is combustion chamber; Described warm-air pipe inwall is symmetrically distributed with the first fireguard, and the first fireguard is other is provided with the second fireguard; The first described fireguard and the second fireguard are all in tile.
Aforesaid have in the hot-blast stove of labyrinth type fire insulation warm-air pipe, and the diameter of the air inlet of described warm-air pipe is greater than the diameter of air outlet.
Compared with prior art, the utility model arranges some first fireguards and the second fireguard on the inwall of warm-air pipe, the inner core of Drying is divided into labyrinth type space by the first fireguard and the second fireguard, when flame in combustion chamber enters warm-air pipe with hot blast, directly can not enter into Drying through warm-air pipe, but flame flows in labyrinth type space along with hot blast, is constantly blocked at flow process Flame, consumes, when hot blast flows into Drying, flame is blocked completely, is consumed; By the effectively isolated flame of this structure, avoiding flame to enter and make material melting in Drying and cohere on equipment and then make equipment corrosion, avoiding the situation affecting the quality of product because corroding the burner stove tail excessive temperature differentials that causes simultaneously.First fireguard and the second fireguard are arranged to tile by the utility model, hot blast is reduced in the flow resistance of warm-air pipe, the diameter of the air inlet of warm-air pipe is set to the diameter being greater than air outlet simultaneously, hot blast is allowed to form draught head at air inlet and air outlet, cause hot blast flow velocity faster, to this increase the drying efficiency of product, thus enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of warm-air pipe.
Being labeled as in accompanying drawing: 1-body of heater, 2-warm-air pipe, 3-Drying, 4-insulating barrier, 5-first fireguard, 6-second fireguard, 7-air inlet, 8-air outlet, 9-combustion chamber.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.Have a hot-blast stove for labyrinth type fire insulation warm-air pipe, form as shown in Figure 1-2, comprise body of heater 1, body of heater 1 is connected with Drying 3 through warm-air pipe 2; The inwall of described body of heater 1 is provided with insulating barrier 4, and the cavity between insulating barrier 4 is combustion chamber 9; Described warm-air pipe 2 inwall is symmetrically distributed with the first fireguard 5, first fireguard 5 side and is provided with the second fireguard 6; The first described fireguard 5 and the second fireguard 6 are all in tile.
During work, fire coal adds hot-air in the combustion chamber 9 of body of heater 1, and the hot-air formation hot blast after heating enters Drying 3 pairs of materials by warm-air pipe 2 dries; In warm-air pipe 2, the inner core of Drying 3 is divided into labyrinth type space by the first fireguard 5 and the second fireguard 6, when flame in combustion chamber 9 enters warm-air pipe 2 with hot blast, flow in labyrinth type space, constantly blocked, consume by the first fireguard 5 and the second fireguard 6 at flow process Flame, when hot blast passes into Drying, along with the flame of flowing is blocked completely, consumes, realize the object of effectively isolated flame.First fireguard 5 and the second fireguard 6 are arranged to tile, and hot blast is reduced in the flow resistance of warm-air pipe.
The diameter of the air inlet 7 of aforesaid warm-air pipe 2 is greater than the diameter of air outlet 8.The diameter of the air inlet 7 of warm-air pipe 2 is set to the diameter being greater than air outlet 8, allows hot blast form draught head between air inlet 7 and air outlet 8, make hot blast flow velocity faster, to this increase the drying efficiency of product.
Claims (2)
1. have a hot-blast stove for labyrinth type fire insulation warm-air pipe, it is characterized in that: comprise body of heater (1), body of heater (1) is connected with Drying (3) through warm-air pipe (2); The inwall of described body of heater (1) is provided with insulating barrier (4), and the cavity between insulating barrier (4) is combustion chamber (9); Described warm-air pipe (2) inwall is symmetrically distributed with the first fireguard (5), and the first fireguard (5) is other is provided with the second fireguard (6); Described the first fireguard (5) and the second fireguard (6) are all in tile.
2. the hot-blast stove with labyrinth type fire insulation warm-air pipe according to claim 1, is characterized in that: the diameter of the air inlet (7) of described warm-air pipe (2) is greater than the diameter of air outlet (8).
