Description

Technical Field

[0001] The utility model relates to the technical field of gas leakage alarm systems, in particular to a combustible gas leakage alarm system. Background Art

[0002] The main component of all-purpose adhesive is chloroprene rubber, which is formed by the polymerization of chloroprene monomer. Chloroprene monomer is obtained by reacting butadiene with chlorine. Butadiene is a colorless, flammable gas with a slight aromatic odor and is insoluble in water. Butadiene is compressed and stored in gas tanks. When the synthesis reaction is needed, the butadiene gas is fed into the reactor.

[0003] Since butadiene is a colorless, flammable gas with a light odor, its leakage is difficult to detect. However, when its leakage concentration reaches a certain range and encounters an open flame, it will cause an explosion. Utility Model Content

The flow regulating screw is arranged vertically upward, and the flow regulating screw is threadedly connected with a locking nut. The bottom side of the locking nut is against the top wall of the flow regulating valve. A pressure tank is provided on the bottom wall of the inner cavity of the protection box. The pressure tank is provided with a pressure gauge. A pressure pipe is connected to the top side of the gas storage tank, and the air outlet of the pressure pipe is connected to the pressure tank. The protection box is connected to a control console, which is provided with a touch screen and an alarm light. The inlet flowmeter, outlet flowmeter, gas transmission flowmeter and pressure gauge are all electrically connected to the control console. A slag cleaning opening is provided on the top wall of the gas storage tank, and the slag cleaning opening is threadedly connected with a closing cover.

[0007] Specifically, the mounting column is provided with an upper tie hoop, a middle tie hoop and a lower tie hoop, the front side of the gas storage tank is fixedly connected with an upper connecting plate and a lower connecting plate, and the upper connecting plate and the lower connecting plate are respectively fixedly connected to the rear sides of the upper tie hoop and the middle tie hoop.

[0008] Specifically, the flow regulating valve is fixed to the front side of the upper binding hoop.

[0009] Specifically, the front sides of the middle tie hoop and the lower tie hoop are both fixedly connected to the rear side of the protection box.

[0010] Specifically, two U-shaped rods are welded to the mounting column, and the height position of the U-shaped rods is between the middle hoop and the lower hoop.

[0013] Specifically, the opening and closing door panel is provided with a door lock.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Butadiene gas is pressurized and fed into a gas storage tank through the tank's air inlet for storage. When butadiene and chlorine are required to produce chloroprene monomer, appropriate amounts of butadiene and chlorine are fed into a reactor (not shown). A flow control valve controls the flow of butadiene gas from the gas storage tank to the reactor, ensuring an appropriate ratio of butadiene to chlorine in the reactor.

[0016] Butadiene gas from the gas storage tank is discharged through the tank outlet and flows into the filter tank through pipe A to remove moisture from the butadiene gas. The butadiene gas flowing out of the filter tank enters the flow control valve through pipe B and is then sent to the reactor (not shown) for reaction.

[0017] A flow regulating screw is provided on the top of the flow regulating valve. By turning the flow regulating screw, the flow of the flow regulating valve can be adjusted, thereby controlling the flow of butadiene delivered to the reactor, thereby ensuring that the ratio of butadiene to chlorine in the reactor is appropriate.

[0018] The pressure-inducing tank is connected to the gas storage tank via a pressure-inducing pipe. The pressure-inducing tank is equipped with a pressure gauge, which is used to monitor the pressure inside the gas storage tank in real time. The inlet flowmeter, outlet flowmeter, gas flowmeter, and pressure gauge are all electrically connected to the control console. The control console calculates the pressure of the remaining gas in the tank based on the inlet flow rate and outlet flow rate. The calculated pressure value is compared with the actual pressure value measured by the pressure gauge. If the difference between the actual pressure value and the calculated pressure value is greater than the set value, it is determined that there is a leak in the system, and the alarm light is turned on to sound an alarm. The touch screen provided on the control console 7 can be used to set parameters.

[0019] Because the pressure gauge needs to accurately measure the pressure in the gas tank in real time, a protective box is used to separate the pressure gauge and the pressure tank and protect them to prevent the pressure gauge from being accidentally touched or damaged, resulting in inaccurate pressure measurement.

[0037] Specifically, the mounting column 1 is provided with an upper tie hoop 11, a middle tie hoop 12 and a lower tie hoop 13.

[0044] The working principle of the combustible gas leakage alarm system of this utility model is as follows:

[0045] Butadiene gas is pressurized and fed into gas tank 2 through gas inlet 21 for storage. When butadiene and chlorine are reacted to produce chloroprene monomer, appropriate amounts of butadiene and chlorine are fed to a reactor (not shown). A flow control valve 5 controls the flow of butadiene gas from gas tank 2 to the reactor, ensuring an appropriate ratio of butadiene to chlorine in the reactor.

[0046] Butadiene gas from gas storage tank 2 is output through tank outlet 22 and flows into filter tank 4 via pipe A to remove moisture from the butadiene gas. The butadiene gas from filter tank 4 is then fed into flow control valve 5 via pipe B and then into a reactor (not shown) for reaction.

[0047] See Figure 4 A flow regulating screw 52 is provided on the top of the flow regulating valve 5. By turning the flow regulating screw 52, ​​the flow of the flow regulating valve 5 can be adjusted, thereby controlling the flow of butadiene supplied to the reactor, thereby ensuring that the ratio of butadiene to chlorine in the reactor is appropriate.

[0048] The pressure-inducing tank 6 is connected to the gas storage tank 2 via a pressure-inducing pipe 62. The pressure-inducing tank 6 is equipped with a pressure gauge 61 for real-time monitoring of the pressure within the gas storage tank 2. The inlet flowmeter 211, outlet flowmeter 221, gas flowmeter 51, and pressure gauge 61 are all electrically connected to the control console 7. The control console 7 calculates the pressure of the remaining gas in the tank based on the inlet and outlet flow rates. The calculated pressure value is then compared with the actual pressure value measured by the pressure gauge 61. If the difference between the actual pressure value and the calculated pressure value is greater than a set value, a leak is detected in the system, and an alarm light 71 is illuminated to sound an alarm. The control console 7 includes a touch screen for parameter settings.

[0049] Since the pressure gauge 61 needs to accurately measure the pressure in the gas storage tank 2 in real time, a protection box 3 is used to separate the pressure gauge 61 and the pressure tank 6 and protect them to prevent the pressure gauge 61 from being accidentally touched or damaged, resulting in inaccurate pressure measurement.
