Description

Technical Field

[0001] This utility model relates to the field of chemical safety equipment technology, specifically a hazardous gas evacuation device. Background Technology

[0002] The characteristics of chemical production make it an industry with a high concentration of hazardous sources. Therefore, it is essential to attach great importance to chemical safety production, establish a sound safety management system, raise employees' safety awareness, and ensure the implementation of safe production practices. Chemical safety management plays a vital role in reducing hazardous factors, preventing accidents, minimizing losses, and protecting people's lives and property.

[0003] Patent publication number CN222837042U discloses an emergency evacuation device for hazardous gases used in chemical safety, including a ventilation pipe and a negative pressure source connected to the ventilation pipe, as well as a mounting bracket, a gas collection hood, a sealing cover, a drive assembly, a detector, and a control key; the gas collection hood is mounted on the mounting bracket and configured to be positioned above a tank used for producing chemicals.

[0004] To address the potential for gas leaks, existing technologies employ a detector to indicate a leak within the tank when the target gas is detected. The controller then controls a drive assembly to slide a sealing cover downwards, placing it over the tank to reduce the likelihood of further gas diffusion. However, leaked gas may still be directly discharged during venting and treatment, leading to environmental pollution or secondary diffusion. Utility Model Content

[0005] This invention addresses the problem that existing gas evacuation devices used in chemical production directly discharge gases during exhaust and treatment, which can easily lead to environmental pollution and secondary diffusion of harmful gases. It provides a harmful gas evacuation device that can simultaneously block leaked hazardous chemical gases from further leakage and rapidly collect and convert harmful gases, preventing residual harmful gases from leaking out and causing secondary diffusion pollution.

[0013] Furthermore, a connecting plate is provided inside the box, and the adsorption plate is slidably disposed on the connecting plate; and the adsorption plate passes through an opening on the side wall of the box and is connected to a fixed plate outside the box.

[0016] Furthermore, there are multiple water pipes, which are obliquely distributed on both sides of the fourth chamber, and the multiple water pipes can form a cross water curtain through spraying.

[0033] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0034] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0035] Example 1

[0036] Existing emergency evacuation devices for hazardous gases in chemical safety can temporarily solve the problem of potential gas leaks. However, their function is generally limited to temporarily blocking the diffusion of gases. When it comes to external discharge and treatment, the gases still need to be discharged directly, which can easily lead to environmental pollution and secondary diffusion of hazardous gases.

[0037] To address the aforementioned problems in the prior art, this embodiment provides a hazardous gas evacuation device. This device is used to protect hazardous gas sources in the chemical industry and to provide emergency response to gas leaks at risk points. This hazardous gas evacuation device can simultaneously block leaked hazardous gases from further leakage and rapidly collect and convert them, preventing residual hazardous gases from causing secondary diffusion and pollution. Please refer to [link to relevant documentation]. Figures 1-5 The hazardous gas evacuation device mainly includes: a cabin 100, a gas handling mechanism 200, and a regulating ventilation mechanism 300, etc.

[0038] The hull 100 is installed above the tank requiring emergency protection to isolate multiple gas leak risk points and external space. The hull 100 is roughly rectangular in shape and hollow internally. Figure 1The diagram shows the internal structure of the chamber 100. A partition 103 is provided in the middle of the chamber 100, which divides the interior of the chamber 100 into a first chamber 110 and a second chamber 120. The first chamber 110 is connected to the gas leakage risk point above the tank and is used to install the regulating ventilation mechanism 300. The second chamber 120 is not connected to the gas leakage risk point above the tank and is used to install the gas handling mechanism 200.

[0039] The regulating exhaust mechanism 300 is used to monitor and extract harmful gas leaks. The regulating exhaust mechanism 300 mainly includes an exhaust fan 309, a gas sensor 308, and a gas duct. The gas sensor 308 is installed on the side wall of the first chamber 110 of the cabin 100 to detect gas leaks. The exhaust fan 309 is located in the first chamber 110, above the gas sensor 308, and is used to extract harmful gases. The gas duct is a flexible spring hose 301, which passes through the partition 103 inside the cabin 100, connecting one end to the exhaust fan 309 and the other end to the gas handling mechanism 200. A control box 306 is also installed in the first chamber 110. The control box 306 is electrically connected to both the gas sensor 308 and the exhaust fan 309. When the gas sensor 308 detects a harmful gas leak, the control box 306 can control the exhaust fan 309 to start extraction.

[0040] The gas treatment mechanism 200 is used to receive harmful gases drawn in and transferred from the regulating exhaust mechanism 300, and to render the harmful gases harmless before further discharging them. The gas treatment mechanism 200 mainly includes a housing 201 and a water storage tank 208. The housing 201 is equipped with an adsorption plate 210, which adsorbs harmful components in the gas and divides the interior of the housing 201 into an upper third chamber 230 and a lower fourth chamber 240. An air inlet 209 is provided on the side wall of the third chamber 230. The air inlet 209 is connected to one end of the spring hose 301 of the regulating exhaust mechanism 300 to introduce harmful gases into the box 201. Inside the fourth chamber 240, and below the adsorption plate 210, several water pipes 212 are provided. The water pipes 212 are inclined, symmetrical and evenly distributed in the fourth chamber 240. They form a cross water curtain by spraying to spray and adsorb the adsorbed gas, so that the particles remaining inside enter the water. Meanwhile, an exhaust port 214 is provided on the side wall of the fourth chamber 240, and an exhaust pipe 205 connected to the exhaust port 214 is provided on the outside of the fourth chamber 240. An exhaust fan 206 is provided on the exhaust pipe 205 to discharge the treated gas. At the same time, a drain pipe 207 is provided at the bottom of the fourth chamber 240. The drain pipe 207 is connected to a water storage tank 208 located below the box body 201, so that the wastewater containing pollutants after the treatment of harmful gases is discharged into the water storage tank 208 for storage.

[0041] One specific working method of this embodiment is as follows:

[0042] When the gas sensor 308 detects harmful gas, the control box 306 starts the exhaust fan 309 to extract the harmful gas. Then, the harmful gas is discharged into the box 201 through the spring hose 301 for rapid discharge. The harmful gas enters the box 201 through the air inlet 209, and the exhaust fan 206 connects to the exhaust port 214 through the exhaust pipe 205 to ventilate the box 201. Inside the box 201, the harmful gas first comes into contact with the adsorption plate 210. After the adsorption plate 210 adsorbs the harmful components, it enters the fourth chamber 240 in the lower layer of the box 201 through the connecting plate 211. The water pipe 212 sprays the adsorbed gas, causing the residual particles inside to condense, and the wastewater is discharged into the water storage tank 208 for collection through the drain pipe 207. The treated gas is discharged through the exhaust pipe 205 and the exhaust fan 206 to avoid direct discharge of harmful gas and secondary pollution.

[0043] In this embodiment, the hazardous gas evacuation device is equipped with a chamber 100. A gas sensor 308 and an exhaust fan 309 are installed in the first chamber 110, which is connected to the hazardous gas leak risk point in the chemical industry, to promptly extract the leaked hazardous gas. The hazardous gas is then transferred through a gas conduit to the housing 201 of the gas treatment mechanism 200 for dual harmless treatment via an adsorption plate 210 and a water pipe 212. The treated gas is then promptly discharged through an exhaust port 214, and the wastewater used for treating the hazardous gas is discharged into a water storage tank 208 for storage and collection. This avoids direct discharge of hazardous gas, preventing secondary pollution and solving the problem in existing chemical production gas evacuation devices where direct discharge during exhaust and treatment easily leads to environmental pollution and secondary diffusion of hazardous gases.

[0044] Furthermore, in this embodiment, inside the housing 201 of the gas treatment mechanism 200, a perforated connecting plate 211 is provided below the adsorption plate 210, and the adsorption plate 210 is slidably disposed above the connecting plate 211. An opening is provided on the side wall of the housing 201 on one side of the adsorption plate 210, and the adsorption plate 210 extends out from this opening and connects to a fixing plate 202 on the outside of the housing 201. The fixing plate 202 is perpendicular to the adsorption plate 210, and a pull ring 204 is provided on the side of the fixing plate 202 away from the housing 201; while a rubber sealing gasket 203 is provided on the side of the fixing plate 202 close to the housing 201, so that the adsorption plate 210 can be pulled out for replacement by pulling the pull ring 204. The rubber sealing gasket 203 on the surface of the fixing plate 202 ensures sealing while preventing easy movement, thereby improving the safety and adaptability of the device. In addition, the outlet ends of several water pipes 212 of the gas processing mechanism 200 in this embodiment are all provided with atomizing nozzles 213. The atomizing nozzles 213 can atomize the water flow sprayed from the water pipes 212, thereby improving the adsorption rate of impurity particles.

[0045] Furthermore, in this embodiment, the ventilation adjustment mechanism 300 is equipped with a number of gas sensors 308, which are spaced apart on the side wall of the first chamber 110 of the cabin 100, for detecting gas leaks at different locations. Furthermore, the regulating exhaust mechanism 300 also has a support frame 303 installed on the inner wall of the first chamber 110 of the cabin 100. The support frame 303 is arranged parallel to the partition 103, and a slide rod 302 is fixedly installed between the support frame 303 and the partition 103. A lead screw 305 is rotatably installed, and the slide rod 302 and the lead screw 305 are arranged parallel to each other. A screw hole and a sliding hole are provided above the exhaust fan 309. The screw hole is adapted to the lead screw 305 and is sleeved on the lead screw 305. The sliding hole is adapted to the slide rod 302 and is slidably sleeved on the slide rod 302. At the same time, a motor 304 is installed on the side of the support frame 303 away from the partition 103. The output end of the motor 304 is connected to one end of the lead screw 305, which can drive the lead screw 305 to rotate. The motor 304 is electrically connected to the control box 306. Therefore, when gas sensors 308 at different locations detect a harmful gas signal, the control box 306 drives the motor 304 on the surface of the support frame 303 to rotate the lead screw 305, causing the exhaust fan 309 to slide along the surface of the slide bar 302 to the gas sensor 308 that detected the harmful gas, enabling more efficient and targeted extraction of the harmful gas. In addition, this embodiment also includes an alarm 307 on the control box 306, electrically connected to the control box 306. When the gas sensor 308 detects a harmful gas leak, the control box 306 can simultaneously activate the alarm 307, providing an audible and visual alarm to alert relevant personnel.
