Description

Technical Field

[0001] The utility model relates to the technical field of fire-blocking devices, and more specifically to a self-draining fire-blocking device. Background Art

[0002] Flame arrester is a safety device used to prevent the spread of flames. It is usually used in systems such as pipelines, storage tanks, and containers to prevent the flames in combustible gases or liquids from spreading to other areas to reduce the risk of explosions and fires. In the RTO system, the pre-treated exhaust gas will be burned. In order to ensure the safety and reliability of the system, it is usually necessary to set a flame arrester between the pre-treatment equipment and the combustion equipment to prevent the flame from spreading through the pipeline to the pre-treatment equipment.

[0003] The water vapor generated during the use of existing fire-blocking devices cannot be discharged in time and will accumulate in the fire-blocking devices. At the same time, the water vapor combined with the combustion residues in the fire-blocking devices can easily block the fire-blocking devices, thereby causing the fire-blocking devices to fail, and the risk of use is relatively high.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the sake of illustration and convenience of description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0019] like Figure 1-3 As shown, the technical solution of the utility model provides a self-draining fire-blocking device, comprising a tank body 1, a fire-blocking tube 5 arranged in the tank body 1, a cleaning assembly 11 located above the fire-blocking tube 5, and a drainage assembly located below the fire-blocking tube 5, wherein the drainage assembly is arranged obliquely from top to bottom. An air inlet pipe 2, an air outlet pipe 3, and a drainage pipe 4 are arranged on the tank body 1, wherein the air inlet pipe 2 is located above the fire-blocking tube 5, the air outlet pipe 3 is located below the drainage pipe 4, and the drainage pipe 4 is located on one side of the drainage assembly.

[0020] The air inlet pipe 2 is connected to the pre-treatment equipment, and the air outlet pipe 3 is connected to the combustion equipment. The exhaust gas flowing out of the pre-treatment equipment passes through the fire-blocking tube 5 and then enters the combustion equipment through the air inlet pipe 2. During the combustion process, if there is a flame, the fire-blocking tube 5 blocks the flame to prevent it from entering the pre-treatment equipment, thereby increasing the safety of the equipment. In this solution, the fire-blocking tube is arranged longitudinally, and a cleaning component 11 and a drainage component are arranged at the same time, so that the liquid generated during the combustion can be discharged. At the same time, the fire-blocking tube 5 can be cleaned after use to avoid blockage of the passage of the fire-blocking tube 5, thereby increasing the safety of use.

[0021] The fire-blocking tube 5 includes a barrel body 6 and a plurality of fire-blocking plates 7 arranged at intervals in the barrel body 6. The fire-blocking plates 7 are corrugated plates and are arranged longitudinally. A gas channel is formed between two adjacent fire-blocking plates 7. When a flame enters the flame arrester, the corrugated structure can block the flame, and the flame will be extinguished after a certain distance. At the same time, the liquid generated by the combustion in the tank body 1 can also flow along the corrugated plate to the drainage assembly at the bottom of the tank body 1 and be discharged through the drainage pipe 4. A support seat 8 is arranged in the tank body 1, and the fire-blocking tube 5 is supported by the support seat 8, which plays a role in supporting and fixing the fire-blocking tube 5.

[0022] The drainage assembly includes an inclined drainage plate 10, and the bottom of the drainage pipe 4 is lower than the lowest point of the drainage plate 10. The inclined drainage plate 10 plays a role in guiding the liquid, and the liquid flows along the drainage plate 10 to the lowest point, enters the drainage pipe 4, and then is discharged.

[0023] The cleaning assembly 11 includes an inner cleaning pipe 12 and an outer cleaning pipe 13 located outside the inner cleaning pipe 12 and used for supplying liquid to the inner cleaning pipe 12. The inner cleaning pipe 12 is provided with a nozzle 14 facing the fire-blocking tube 5. The outer cleaning pipe 13 is arranged in a ring shape, and a plurality of inner cleaning pipes 12 are arranged in a cross-arrangement. The inner cleaning pipe 12 is communicated with the outer cleaning pipe 13, and the outer cleaning pipe 13 is connected with a liquid supply pipe 15.

[0024] The cleaning component 11 cleans the fire-blocking plate 7 after the exhaust gas treatment is completed. During cleaning, the liquid is supplied to the outer cleaning tube 13 through the liquid supply pipe 15, and the outer cleaning tube 13 supplies liquid to the inner cleaning tube 12. The cleaning liquid is sprayed on the fire-blocking plate 7 by the nozzle 14 to clean the fire-blocking plate 7, thereby removing the solid pollutants attached to the fire-blocking plate 7 to avoid channel blockage. The cleaning liquid is pure water. The cleaned wastewater flows along the fire-blocking plate 7 to the cleaning plate, and then is discharged from the drain pipe 4.

[0025] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
