Description

Technical Field

[0001] The utility model relates to the technical field of chemical storage tanks, in particular to a storage tank wall safety protection device. Background Art

[0002] During the chemical production process, a reinforcement ring welded around the tank wall is installed on the upper part of the atmospheric pressure storage tank wall to prevent the tank from deforming. The reinforcement ring is welded with angle steel and protrudes from the tank wall by about 10cm. The materials stored in some storage tanks need to be insulated, and insulation cotton and insulation boards are installed on the tank wall. During the rainy season, rainwater is retained around the tank wall by the reinforcement ring. Because the tank wall is insulated, the rainwater cannot be dried in time. The reinforcement ring is close to the tank wall because of moisture retention and interacts with the insulation cotton of the storage tank. Long-term action causes corrosion at this position, thinning the tank wall, and severe corrosion and perforation of the tank wall. The material in the tank leaks out, and static electricity can cause fire and explosion safety accidents when exposed to open flames. Utility Model Content

[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0026] See also Figure 1 In one embodiment of the utility model, a storage tank wall safety protection device is used for blowing air to the reinforcement ring 10 of the storage tank wall 20, which includes a plurality of brackets 100, an annular air duct 200, a plurality of air nozzles 300 and an air supply main pipe 400; the annular air duct 200 is sleeved on the storage tank 1 and is detachably connected to the bracket 100 so that the annular air duct 200 is kept above the reinforcement ring 10; a plurality of air nozzles 300 are fixed and connected to the annular air duct 200, and the air nozzles 300 face the reinforcement ring 10 to blow air to the joint between the reinforcement ring 10 and the storage tank wall 20; the air supply main pipe 400 is connected to the annular air duct 200, and an air supply control valve 410 is provided on the air supply main pipe 400.

[0027] The above-mentioned tank wall safety protection device is installed on the outside of the tank wall 20. When the humidity exceeds the threshold, the air supply control valve 410 is opened to supply air to the reinforcement ring 10 to dry the joint between the reinforcement ring 10 and the tank wall 20, thereby ensuring that the corrosion of the tank wall 20 is reduced to ensure the safety of the tank 1. In addition, when specifically set, the air supply control valve 410 is preferably installed at the boundary area of ​​the tank area.

[0028] In one embodiment, a humidity measuring instrument 500 for measuring the humidity on the upper surface of the reinforcement ring 10 is disposed on the reinforcement ring 10 .

[0029] In one embodiment, the humidity measuring instrument 500 is electrically connected to the PLC device 600, and the PLC device 600 is connected to the air supply control valve 410; when the measured humidity exceeds the threshold, the humidity measuring instrument 500 sends a signal to the PLC device 600, and the PLC device 600 controls the air supply control valve 410 to open. The humidity measuring instrument 500 can be specifically installed at the connection between the reinforcement ring 10 and the tank wall 20.

[0030] It should be noted that, in the above embodiment, a humidity measuring instrument 500 is provided on the upper surface of the reinforcement ring 10, and a threshold value of the humidity measuring instrument 500 is pre-set, for example, set to 30%. Then, when the humidity on the upper surface of the reinforcement ring 10 measured by the humidity measuring instrument 500 is greater than 30%, the humidity measuring instrument 500 sends a signal to the PLC device 600 of the remote control system, and the PLC device 600 controls the air supply control valve 410 to open, and the industrial air enters the annular air duct 200 through the air supply main pipe 400, and is then blown out from the air nozzle 300 to blow and dry the reinforcement ring 10.

[0031] In one embodiment, the bracket 100 is detachably fixed to the tank wall 20. In another embodiment, the bracket 100 is detachably fixed to the reinforcement ring 10. It should be noted that the fixing position of the bracket 100 can be the tank wall 20 or the reinforcement ring 10. Preferably, the tank wall 20 is selected for installation, which can effectively avoid the bracket 100 from causing a purge blind area and affecting the drying effect. The installation method is not limited, and it can be detachably fixed using bolts and other connectors.

[0032] See also Figure 2 In one embodiment, a plurality of guide holes 11 are formed on the reinforcing ring 10. Further, based on the above embodiment, two air nozzles 300 are correspondingly disposed above each guide hole 11, and the air nozzles 300 are tilted to align with the guide hole 11.

[0033] The guide hole 11 of the tank wall safety protection device is provided to play a drainage role when air is supplied. In addition, the reinforcement ring 10 can be purged through the two air nozzles 300 on both sides, so that the water droplets on the upper part are quickly drained from the upper surface of the reinforcement ring 10 to the guide hole 11 and dripped under the action of the wind, which improves the drying efficiency to a certain extent. Figure 2 , Figure 3 The direction of the arrow is the wind direction.

[0034] See also Figure 3 In one embodiment, a plurality of air deflector mounting holes 12 are provided on the reinforcing ring 10, and an air deflector 13 is detachably fixed on the air deflector mounting hole 12, and the air deflector 13 is a conical funnel. Further, based on the above embodiment, two air nozzles 300 are correspondingly provided above each air deflector 13, and the air nozzles 300 are tilted to align with the air deflector 13.

[0035] The above-mentioned tank wall safety protection device can blow the reinforcement ring 10 through the two wind nozzles 300 on both sides, so that the water droplets on the upper part can be quickly drained from the upper surface of the reinforcement ring 10 to the guide cover 13 and drip under the action of wind, which improves the drying efficiency to a certain extent. Since the guide cover 13 is a conical funnel, it can effectively avoid water accumulation on the upper part of the reinforcement ring 10 and play a role in draining the water flow.

[0036] Preferably, in one embodiment, a plurality of brackets 100 are arranged at equal intervals, so that the annular air duct 200 is fixed more firmly, thereby improving the reliability of the device.
