Abstract
A kind of auxiliary flue, is made up of T-shaped stainless steel cask (1), Hand-operated butterfly valve (2), insulated pouring material (3) and cold air duct (4); It is characterized in that: described T-shaped stainless steel cask (1) side puts in heat treatment furnace (5) burner hearth, upper end is connected on main chimney (6), and lower end is connected on cold air duct (4).The utility model, by arranging an auxiliary flue with cold air duct (4) and Hand-operated butterfly valve (2) in the side of heat treatment furnace (5), when furnace pressure uprises, auxiliary smoke evacuation, reduces furnace pressure, avoids furnace pressure too high, forms potential safety hazard.
Description
Technical field
The utility model relates to the heat treatment furnace field in industrial furnace, the auxiliary flue in especially a kind of heat treatment furnace.
Background technology
Known regenerative gas heat treatment furnace generally adopts steel flue and coordinates induced draft fan to discharge fume, when burner hearth burner flame commutates, furnace pressure moment becomes suddenly large and butterfly valve on flue can not give a response immediately, causes furnace pressure too high, forms potential safety hazard to production.
Summary of the invention
For above deficiency, the purpose of this utility model is to provide a kind of auxiliary flue, is arrange an auxiliary flue with Hand-operated butterfly valve in the side of heat treatment furnace, helps heat treatment furnace to discharge flue gas, reduce furnace pressure, ensure safety in production.
The technical solution of the utility model is achieved in the following ways
:a kind of auxiliary flue, be made up of T-shaped stainless steel cask, Hand-operated butterfly valve, insulated pouring material and cold air duct, the side of described T-shaped stainless steel cask puts in burner hearth, and upper and lower two ends are in line, parallel with heat treatment furnace; Described cold air duct is arranged on the lower end of T-shaped stainless steel cask; It is characterized in that: described T-shaped stainless steel cask side puts in heat treatment furnace burner hearth, and upper end is connected on main chimney, and lower end is connected on cold air duct.
The top of described T-shaped stainless steel cask is provided with Hand-operated butterfly valve.
Described T-shaped stainless steel cask outer wrap has insulated pouring material.
The utility model, by arranging an auxiliary flue with cold air duct and Hand-operated butterfly valve in the side of heat treatment furnace, when furnace pressure uprises, auxiliary smoke evacuation, reduces furnace pressure, avoids furnace pressure too high, forms potential safety hazard.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: 1 is T-shaped stainless steel cask, and 2 is Hand-operated butterfly valves, 3 is insulated pouring material, and 4 is cold air ducts, and 5 is heat treatment furnaces, and 6 is main chimneys.
Embodiment
Known by Fig. 1, a kind of auxiliary flue, be made up of T-shaped stainless steel cask 1, Hand-operated butterfly valve 2, insulated pouring material 3 and cold air duct 4, the side of described T-shaped stainless steel cask 1 puts in heat treatment furnace 5 burner hearth, and upper and lower two ends are in line, parallel with heat treatment furnace 5; Described T-shaped stainless steel cask 1 upper end is connected on main chimney 6, and lower end is connected on cold air duct 4; The top of described T-shaped stainless steel cask 1 is also provided with Hand-operated butterfly valve 2, and outer wrap has insulated pouring material 3.
During work, when heat treatment furnace 5 smooth running, first cold air duct 4 is opened, then the angle of Hand-operated butterfly valve 2 is regulated, when the cold wind that cold air duct 4 is introduced and auxiliary flue drain into the air quantity of main chimney 6 roughly the same time, by locked for Hand-operated butterfly valve 2, at this time due to the cold wind introduced by cold air duct 4 and auxiliary flue, to drain into the air quantity of main chimney 6 roughly equal, the pressure of auxiliary flue is substantially equal with the pressure in stove, and the flue gas in stove is discharged fume from original pipeline substantially; When the commutation of burner hearth burner flame, after furnace pressure raises, furnace pressure is greater than the pressure in auxiliary flue, and the flue gas in stove just enters auxiliary flue, is then discharged by main chimney 6; Along with flue gas is after auxiliary flue discharge, furnace pressure also reduces.
The outside of T-shaped stainless steel cask 1 is also enclosed with insulated pouring material 3, helps heat treatment furnace 5 to be incubated, and reduces heat and scatters and disappears from auxiliary flue; The cold air duct 4 that T-shaped stainless steel cask 1 bottom connects is not only for maintaining pressure equilibrium, and the cold wind of introduction is also lowered the temperature to the Hand-operated butterfly valve 2 in auxiliary flue, and the high-temperature flue gas avoiding heat treatment furnace 5 to discharge is burnt out.
The utility model, by arranging an auxiliary flue with cold air duct 4 and Hand-operated butterfly valve 2 in the side of heat treatment furnace 5, when furnace pressure uprises, auxiliary smoke evacuation, reduces furnace pressure, avoids furnace pressure too high, forms potential safety hazard.
Claims (3)
1. an auxiliary flue, is made up of T-shaped stainless steel cask (1), Hand-operated butterfly valve (2), insulated pouring material (3) and cold air duct (4); It is characterized in that: described T-shaped stainless steel cask (1) side puts in heat treatment furnace (5) burner hearth, upper end is connected on main chimney (6), and lower end is connected on cold air duct (4).
2. one according to claim 1 assists flue, it is characterized in that: the top of described T-shaped stainless steel cask (1) is also provided with Hand-operated butterfly valve (2).
3. one according to claim 1 assists flue, it is characterized in that: the outer wrap of described T-shaped stainless steel cask (1) has insulated pouring material (3).
