Abstract
The utility model discloses an emergency stopping device used for a gas heating furnace, which comprises a gas delivery pipe, wherein the gas delivery pipe is provided with a rapid cut-off valve; therapid cut-off valve is connected with at least one gas delivery branch pipe; and the gas delivery branch pipes are respectively provided with a gas adjusting valve. The emergency stopping device is also provided with a gas storage tank; and the gas storage tank is connected with pipelines at the outlet ends of all gas adjusting valves respectively by low-pressure nitrogen purging pipes provided with solenoid valves. The emergency stopping device can rapidly realize emergency stop of the gas heating furnace so as to guarantee human safety.
Description
Technical field
The utility model relates to a kind of gas-fired furnace with urgent blowing out device.
Background technology
The fuel that the plate of moderate thickness pusher-type furnace uses is mixed gas, in use run into power failure, cut off the water, need urgent blowing out under the blowing-out machine situation, need operator to reach the spot rapidly during blowing out and close burner, if above-mentioned situation occurs in night or operator react untimely sky, gaspipe line tempering, blast, the gas leak of just causing probably, can cause casualties when serious.
The utility model content
The purpose of this utility model is to provide a kind of gas-fired furnace with urgent blowing out device, can fast and effeciently realize the blowing out operation, guarantees personnel safety.
The purpose of this utility model is achieved in that a kind of gas-fired furnace is with urgent blowing out device, comprise gas conveying tube, repid cut-off valve is installed on gas conveying tube, and repid cut-off valve is connecting at least one coal gas and is carrying arm, and coal gas is carried on the arm gas regulator is installed respectively; This device also is provided with a gas-holder, and gas-holder links to each other with the pipeline of each gas regulator exit end by the low-pressure nitrogen scavenging duct that magnetic valve is housed respectively.
Repid cut-off valve is set on gas conveying tube, nitrogen purging interface (solenoid control) is set behind each branch road gas regulator, be lower than 3000pa when gas main pressure occurring, air pressure is lower than 4000pa, when instrument air pressure is lower than the wherein any situation of 0.3MPa, process furnace will carry out urgent blowing out: the repid cut-off valve on the gas conveying tube and the gas regulator of each branch road are closed simultaneously, meanwhile the magnetic valve behind the branch road gas regulator is opened automatically in gas line and is charged into low-pressure nitrogen, coal gas to the gaspipe line between the burner behind the branch road gas regulator is cemented out, burner extinguishes, and nitrogen purging will be closed in 10 minutes automatically.The utility model has been realized the blowing out operation of Long-distance Control fully, need not artificial scene and closes burner, guarantees personnel safety.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a syndeton synoptic diagram of the present utility model.
Embodiment
A kind of gas-fired furnace is with urgent blowing out device, as shown in drawings, comprise gas conveying tube 7, repid cut-off valve 8 is installed on gas conveying tube 7, repid cut-off valve 8 is connecting at least one coal gas and is carrying arm 9, and coal gas is carried on the arm 9 gas regulator 2 is installed respectively; This device also is provided with a gas-holder 1, and gas-holder 1 links to each other with the pipeline of each gas regulator 2 exit end by the low-pressure nitrogen scavenging duct 5 that magnetic valve 3 is housed respectively.Gas-holder 1 internal memory is placed with low-pressure nitrogen, when gas main pressure is lower than set(ting)value, repid cut-off valve 8 and gas regulator 2 are closed simultaneously, and at this moment, magnetic valve 3 is opened, low-pressure nitrogen in the gas-holder 1 is entered in the exit end pipeline at gas regulator 2 rear portions, wherein remaining coal gas is replaced, burner is extinguished, and need not manually to carry out site work, improve working efficiency and automatic control level greatly, eliminated the generation of human casualty accident.
Bypass is being provided with the arm 6 that stopcock 4 is housed respectively on the pipeline that magnetic valve 3 is installed.In order to when magnetic valve 3 breaks down, to use, guarantee system's works better as the backup pipeline.
Claims (2)
1, a kind of gas-fired furnace is with urgent blowing out device, comprise gas conveying tube, it is characterized in that: repid cut-off valve is installed on gas conveying tube, and repid cut-off valve is connecting at least one coal gas and is carrying arm, and coal gas is carried on the arm gas regulator is installed respectively; This device also is provided with a gas-holder, and gas-holder links to each other with the pipeline of each gas regulator exit end by the low-pressure nitrogen scavenging duct that magnetic valve is housed respectively.
2, gas-fired furnace according to claim 1 is characterized in that with urgent blowing out device: bypass is being provided with the arm that stopcock is housed being equipped with on the pipeline of magnetic valve respectively.
