DETAILED DESCRIPTION

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Example 1: A chlorine gas leakage absorption device for graphite purification, such as Figure 1-Figure 3 As shown, it includes a closed room, a base frame, a support frame, an absorption device, a spraying device and a detection device. The closed room is set on the ground, the base frame is set on the ground, the support frame is welded on the base frame, the absorption device is set on the base frame, the spraying device is set on the base frame, and the detection device is set in the closed room.

[0015] Furthermore, the absorption device includes an absorption tank, a through pipe, an air pump, a one-way valve, an exhaust pipe, an exhaust valve, a liquid outlet pipe and a liquid outlet valve. The absorption tank is welded to the upper part of the base frame, and a through pipe is connected between the absorption tank and the closed room through a flange. The air pump is welded on the support frame, and the air pump is connected to the through pipe, and a one-way valve is provided on the through pipe. An exhaust pipe is connected to one side of the absorption tank through a flange, and the exhaust pipe is connected to the inside of the absorption tank. An exhaust valve is provided on the exhaust pipe. The bottom of the absorption tank is connected to the liquid outlet pipe through a flange, and a liquid outlet valve is provided on the liquid outlet pipe.

[0016] Furthermore, the spraying device includes a liquid storage tank, a cover plate, a liquid extraction pump, a second through pipe, a hollow frame, a spray plate, a nozzle and a motor. A liquid storage tank is provided on the upper part of the base frame, a cover plate is clamped on the upper part of the liquid storage tank, a liquid extraction pump is welded on the upper part of the base frame, a second through pipe is connected to the lower part of the liquid storage tank through a flange, the second through pipe is connected to the interior of the liquid storage tank, and the second through pipe is connected to the liquid extraction pump. A hollow frame is provided on the upper part of the absorption tank, the hollow frame is fixedly connected to the second through pipe, the interior of the hollow frame is connected to the second through pipe, the upper part of the absorption tank is rotatably connected to the spray plate, the interior of the spray plate is connected to the interior of the hollow frame, a number of nozzles are provided at the bottom of the spray plate, a motor is welded on the upper part of the absorption tank, and the output shaft of the motor is fixedly connected to the spray plate.

[0017] Furthermore, the detection device includes a chlorine gas detector and an alarm. A chlorine gas detector is provided at the upper part of the enclosed room. The alarm is electrically connected to the chlorine gas detector, the alarm is electrically connected to the air pump, the alarm is electrically connected to the liquid pump, and the alarm is electrically connected to the motor.

[0018] First, manually remove the cover plate and pour the absorption liquid into the liquid storage tank, then manually re-attach the cover plate to the liquid storage tank, and then manually start the chlorine detector and alarm. The chlorine detector will detect the chlorine content in the closed room. When the chlorine content in the closed room reaches a certain amount, the alarm will sound and start the vacuum pump, liquid pump and motor. The vacuum pump will draw the chlorine in the closed room into pipe one, and the chlorine will enter the absorption tank along pipe one. The liquid pump will draw the absorption liquid in the liquid storage tank into pipe two, and the absorption liquid will enter the hollow frame along pipe two, and then flow into the spray plate. The output shaft of the motor drives the spray plate and several sprays. As the head rotates, several nozzles will spray the absorption liquid while rotating, so that the chlorine is neutralized more evenly. After the chlorine concentration in the closed room drops, the alarm will no longer sound. After that, the device will run for a period of time, and the exhaust valve and the liquid outlet valve will be opened manually. The treated gas will be discharged from the exhaust pipe, and the residual liquid in the absorption tank will flow out along the liquid outlet pipe. In this way, the chlorine concentration in the closed room can be detected and the chlorine can be absorbed, so that the chlorine concentration in the closed room drops rapidly. The absorption liquid can also be evenly sprayed on the chlorine in the absorption tank, so that the chlorine neutralization effect is better, thereby improving the chlorine treatment effect during graphite purification.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
