Abstract
The utility model discloses an explosion-proof pipe, have the open-ended barrel including an upper end, the waste gas pipe inserts the barrel from this opening one side of barrel is provided with the takeover for connect and burn burning furnace, the position of takeover is higher than the mouth of pipe of waste gas pipe. After adopting this kind of structure, it is possible because of other reasons stop work to burn the burning furnace draught fan, burning waste gas when the furnace negative pressure of burning furnace is not enough, flame pushes back toward waste gas import direction from the furnace that burns burning furnace, because the waste gas pipe inserts 300mm in the blast proof pipe, and the mouth of pipe of waste gas pipe is less than the takeover position, consequently flame can't directly get into in the waste gas pipe, simultaneously because hot gas up walks away, can not follow the bottom and get into the waste gas pipe and be responsible for, can only stop in the blast proof pipe, thereby the backfire accident that causes after having avoided the direct access waste gas pipeline of burning things which.
Description
Technical field
The utility model belongs to the incinerator technical field, is specifically related to the employed explosion stack of a kind of incinerator.
Background technology
Regular meeting produces some combustible exhaust gas in the time of in the Production in Chemical Plant process, and these treatment of waste gas are generally adopted combustion power generation or heating, and combustion process is carried out in incinerator, and waste gas enters incinerator by waste line.Yet in the process of incinerator burnt gas, the incinerator air-introduced machine might be because other reason quits work, this just causes the waste gas accident on the waste line to stop to enter incinerator, thereby pressure combustion in burner hearth, owing to also leave the part residual exhaust gases on the waste line, therefore flame just might enter waste line from the incinerator burner hearth and utilize this residual exhaust gases in-line burning, thereby accidents caused.
Summary of the invention
Technical problem to be solved in the utility model is to occur in problem in the waste line at waste line because of waste gas supply accident stops to make waste gas burning, and a kind of gas pipeline explosion-protection equipment is provided.
The utility model solves this technical problem by following scheme:
A kind of explosion stack comprises that a upper end has the cylindrical shell of opening, and flue gas leading inserts cylindrical shell from this opening, is provided with adapter in a side of described cylindrical shell, and in order to connect incinerator, the position of described adapter is higher than the mouth of pipe of described flue gas leading.
Described flue gas leading inserts in the cylindrical shell at least more than 300mm.
After adopting this structure, might be at the incinerator air-introduced machine because other reason quits work, burnt gas is when the combustion chamber draft of incinerator is not enough, flame returns back to top toward the exhaust gas inlet direction from the burner hearth of incinerator, because flue gas leading inserts 300mm in the explosion stack, and the mouth of pipe of flue gas leading is lower than takes over the position, therefore flame can't directly enter in the flue gas leading, simultaneously owing to the gas of heat is up walked, can not enter flue gas leading from the bottom is responsible for, can only rest in the explosion stack, thereby avoid burning things which may cause a fire disaster directly to insert the tempering accident that causes after the waste line.
Below in conjunction with accompanying drawing to coming the utility model is described further with the specific embodiment:
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, a kind of explosion stack, comprise that a upper end has the cylindrical shell 5 of opening 2, flue gas leading 1 inserts 300mm in the cylindrical shell 5 from this opening 2, side at cylindrical shell 5 is provided with adapter 3, take over 3 the mouth of pipe 4 in order to connect the incinerator (not shown), wherein take over the mouth of pipe 6 that 3 position is higher than flue gas leading 1.
Might be at the incinerator air-introduced machine because other reason quits work, burnt gas is when the combustion chamber draft of incinerator is not enough, flame returns back to top toward the exhaust gas inlet direction from the burner hearth of incinerator, because flue gas leading 1 inserts the cylindrical shell 5 interior 300mm of explosion stack, and the mouth of pipe 6 of flue gas leading 1 is lower than takes over 3 positions, therefore flame can't directly enter in the flue gas leading 1, simultaneously owing to the gas of heat is up walked, can not enter flue gas leading 1 from the bottom is responsible for, can only rest in the explosion stack, thereby avoid burning things which may cause a fire disaster directly to insert the tempering accident that causes after the waste line.
Should be appreciated that those skilled in the art can make various changes or modifications the present invention after having read instruction foregoing of the present invention, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Claims (2)
1. an explosion stack is characterized in that, comprises that a upper end has the cylindrical shell of opening, and flue gas leading inserts cylindrical shell from this opening, is provided with adapter in a side of described cylindrical shell, and in order to connect incinerator, the position of described adapter is higher than the mouth of pipe of described flue gas leading.
2. explosion stack as claimed in claim 1 is characterized in that, described flue gas leading inserts in the cylindrical shell at least more than 300mm.
