Description

Technical Field

[0001] This utility model belongs to the field of hazardous waste storage technology, and in particular relates to a hazardous waste warehouse. Background Technology

[0002] Hazardous waste generated by the petrochemical industry is generally flammable and explosive. Therefore, the design of hazardous waste warehouses for storing these hazardous wastes requires the use of explosion-proof architecture. This means using explosion-proof walls to construct the walls of the hazardous waste warehouse and lightweight explosion-proof roofs to construct the roofs. Some walls may be equipped with explosion-proof windows. The lightweight explosion-proof roofs should have measures to prevent the accumulation of ice and snow to eliminate the impact of the forces generated by snow and ice on the delayed release of pressure relief facilities.

[0003] Chinese invention patent application CN114439164A discloses a snow robot for easy snow removal from roofs in winter. It includes a moving mechanism and a cleaning mechanism on the lower side of the moving mechanism. The cleaning mechanism is equipped with two scrapers and heating rods at the scrapers. When the heating rods are powered on, they heat and melt the snow, so that the snow melts into water and flows down the roof.

[0004] As described above, the heating rods are exposed above the explosion-proof roof. When heating, the heat cannot be concentrated and directed to the explosion-proof roof, resulting in poor heating and snow removal effects. In addition, existing hazardous waste warehouses lack temperature control measures. During storage, hazardous waste releases heat due to fermentation and reactions, causing the temperature inside the hazardous waste warehouse to rise. Higher temperatures will accelerate the deterioration of waste and the generation of exhaust gases, which is not conducive to storage.

[0005] To solve the above-mentioned technical problems, it is necessary to provide a hazardous waste warehouse with better snow removal effect through heating. Utility Model Content

[0006] In view of this, the present invention proposes a hazardous waste warehouse, which uses a heat collection hood to concentrate the heat emitted by the heating rods and direct it to the explosion-proof roof to improve the heating and snow removal effect.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This utility model embodiment provides a hazardous waste warehouse, such as Figure 1-9As shown, the hazardous waste warehouse includes: an explosion-proof roof 1, a warehouse body 2, and a linear drive mechanism 3. The explosion-proof roof 1 is installed on the warehouse body 2; the linear drive mechanism 3 is installed on the explosion-proof roof 1; it also includes a heating rod 4 and a heat collection cover 5. The heating rod 4 is fixedly installed inside the heat collection cover 5; the heat collection cover 5 is arranged parallel to the explosion-proof roof 1 and is fixedly installed on the output end of the linear drive mechanism 3; the end of the heat collection cover 5 facing the explosion-proof roof 1 is open; the linear drive mechanism 3 drives the heat collection cover 5 and the heating rod 4 to reciprocate above the explosion-proof roof 1 along a first preset direction, which is a straight line parallel to the explosion-proof roof 1; a refrigeration device 35 is fixedly installed on the warehouse body 2, and the refrigeration device 35 is used to cool the inside of the warehouse body 2; a housing 36 is fixedly installed on the warehouse body 2, and a controller 38 is fixedly installed on the inner wall of the housing 36. A temperature sensor 37 is provided inside the housing 36, and the probe of the temperature sensor 37 extends into the interior of the warehouse body 2.

[0034] In this embodiment, the explosion-proof roof 1 is a lightweight explosion-proof roof with a mass of no more than 60 kg / m². The linear drive mechanism 3 on the explosion-proof roof 1 is an electric linear module, and two are symmetrically installed on the explosion-proof roof 1. The heating rod 4 is an electric heating rod. The sliders of the two electric linear modules are fixedly connected to the heat collection cover 5 by bolts. When the two electric linear modules are powered on, their sliders jointly drive the heat collection cover 5 and the heating rod 4 inside it to reciprocate along the first preset direction. During the reciprocating translation, the heating rod 4 is powered on and heated to continuously melt the snow falling on the explosion-proof roof 1. During the use of this hazardous waste warehouse, the temperature sensor 37 will continuously detect the indoor temperature. When the indoor temperature is higher than the set temperature, the controller 38 will immediately start the refrigeration equipment 35 to cool the interior of the warehouse body 2 until the temperature reaches the standard value. Only then will the controller 38 stop the operation of the refrigeration equipment 35. This ensures that the indoor temperature is at the optimal level, preventing the deterioration of waste and the generation of exhaust gas, which is beneficial for the storage of hazardous waste.

[0035] In the above structure, the heat collection cover 5 constrains the heat emitted by the heating rod 4, allowing the heat to be discharged from the opening, which facilitates the concentration and guidance of the heat to the explosion-proof roof 1, improving the heating and snow removal effect. The cooling equipment 35 can cool the room when the indoor temperature is high, which is beneficial for waste storage.

[0036] In a further preferred embodiment of the present invention, a plurality of fans 41 are provided on the side of the heating rod 4 away from the explosion-proof roof 1. The plurality of fans 41 are fixed at intervals on the inner side of the heat collection cover 5 along a straight line direction perpendicular to the first preset direction. The plurality of fans 41 are used to blow air toward the explosion-proof roof 1.

[0037] In this embodiment, as Figure 3-4As shown, when the fan 41 is powered on, it blows air towards the explosion-proof roof 1. The heating rod 4 is set in the air blowing direction of the fan 41. Therefore, the air blown out from the opening of the heat collection cover 5 is hot air. The snow is melted by the hot air, and the snow removal effect is better.

[0038] In a further preferred embodiment of the present invention, the inner surface of the heat collection cover 5 is covered and fixed with a heat insulation layer 51.

[0039] In this embodiment, as Figure 4 As shown, the thermal insulation layer 51 is made of aluminum foil insulation cotton, which makes it difficult for the heat emitted by the heating rod 4 to be transferred to the outside through the outer wall of the heat collection cover 5, resulting in less heat loss.

[0040] In a further preferred embodiment of the present invention, the warehouse body 2 includes a plurality of wall beams 21 and a plurality of explosion relief walls 22. The explosion relief walls 22 are connected to the wall beams 21 to form the outer wall of the warehouse. The explosion relief walls 22 and the wall beams 21 are connected by a cable 201. One end of the cable 201 is fixed to the explosion relief wall 22 and the other end is fixed to the wall beam 21.

[0041] In this embodiment, as Figure 5-6 As shown, the explosion relief wall 22 uses an external wall panel with a unit mass of no more than 60 kg / m² for explosion relief and is fixedly installed with explosive bolts. In order to prevent the explosion relief wall 22 from flying around in the event of an explosion, an index cable control is set between the explosion relief wall 22 and the wall beam 21. That is, a cable 201 is set between the explosion relief wall 22 and the wall beam 21, and the explosion relief wall 22 is pulled by the cable 201.

[0042] In addition, the explosion relief wall 22 can also be made of fiber-reinforced cement board. The fiber-reinforced cement board wall is composed of brittle cement sheet, light steel keel and rock wool. It has the characteristics of lightweight insulation. When it explodes, it is in block or powder form and is not likely to cause secondary damage. Alternatively, the existing technology of expanded stone lightweight board wall or foam concrete composite board wall can be used. Explosion relief windows can be installed on the explosion relief wall 22 to increase the brightness in the warehouse. The explosion relief windows are made of safety glass, a material that does not produce sharp fragments when it explodes. The explosion relief windows are not shown in the illustration.

[0043] In a further preferred embodiment of this utility model, the warehouse body 2 is fixedly installed on the ground, and the ground inside the warehouse body 2 forms the warehouse floor; the height of the warehouse floor is greater than the height of the ground outside the warehouse body 2, and the warehouse floor is provided with a slope.

[0044] In this embodiment, as Figure 7 As shown, the warehouse floor is higher than the ground outside the warehouse body 2, making it difficult for water to enter the warehouse and helping to prevent moisture. The warehouse floor is a non-sparking surface, so that static electricity or sparks will not be generated due to friction of objects during use, which could lead to the explosion of materials. The warehouse floor is sloped at 1%, which can cause the seepage of materials in the warehouse to converge in one direction.

[0045] In a further preferred embodiment of this utility model, a waste liquid collection ditch 23 is provided at the lower slope of the warehouse floor. The bottom of the waste liquid collection ditch 23 is sloped. A waste liquid collection pit 24 is provided at the lower slope of the waste liquid collection ditch 23. The waste liquid collection pit 24 is connected to the waste liquid collection ditch 23. A filter screen 32 and a support base 28 are fixedly installed on the inner wall of the collection pit 24. A protective shell 29 is fixedly installed on the support base 28. A motor 30 is fixedly installed on the inner wall of the protective shell 29. A rotating shaft 31 is fixedly installed on the output shaft of the motor 30. The rotating shaft 31 is rotatably connected to the protective shell 29 in a sealed manner. The rotating shaft 31 is slidably connected to the filter screen 32. Two horizontal plates 33 are fixedly installed on the rotating shaft 31. A brush 34 is fixedly installed on each of the two horizontal plates 33.

[0046] In this embodiment, as Figure 5 , Figure 8 and Figure 9 As shown, the bottom slope of the waste liquid collection ditch 23 is 1%. The waste liquid collection ditch 23 is located at the low slope of the warehouse floor. The seepage of materials in the warehouse can be collected in the waste liquid collection ditch 23 and then flow into the waste liquid collection pit 24 along the slope of the waste liquid collection ditch 23. The waste liquid collection pit 24 is a settling tank structure. With the use of the filter screen 32, the waste liquid flowing into the waste liquid collection pit 24 can be filtered, and impurities in the waste liquid can be blocked, effectively preventing these impurities in the liquid from clogging the downstream pipes. When it is necessary to clean the filter screen 32, the motor 30 is started. The motor 30 will drive the rotating shaft 31 to rotate. The rotating shaft 31 will drive the two horizontal plates 33 to rotate. The two horizontal plates 33 will drive the two brushes 34 to clean the impurities on the filter screen 32 to prevent the mesh of the filter screen 32 from becoming clogged.

[0047] In a further preferred embodiment of the present invention, a waste liquid collection pool 25 is provided on the outside of the warehouse body 2. The waste liquid collection pool 25 is connected to the waste liquid collection pit 24 through a pipe, and the height of the waste liquid collection pool 25 is lower than the height of the waste liquid collection pit 24.

[0048] In this embodiment, as Figure 8 As shown, the wastewater in the wastewater collection pit 24 flows through pipes to the wastewater collection tank 25. The size and depth of the wastewater collection tank 25 are matched with the volume of liquid stored in the warehouse. The liquid in the wastewater collection tank 25 is recycled and treated by a professional wastewater treatment company.

[0049] In addition, materials in the petrochemical industry are generally polluting. Therefore, the warehouse floor and the surfaces of waste liquid collection ditches 23, waste liquid collection pits 24 and waste liquid collection pools 25 are all treated with anti-seepage materials. Specifically, anti-seepage concrete is used, with a strength grade of not less than C25, an anti-seepage grade of not less than P6 and a thickness of not less than 100mm. Alternatively, an anti-seepage layer of at least 1m thick clay or at least 2mm thick high-density polyethylene membrane or other anti-seepage materials can be used.

[0050] In a further preferred embodiment of the present invention, a warehouse door 26 is provided at a high point on the warehouse floor. The warehouse door 26 is installed on the outer wall of the warehouse. A threshold 202 is provided at one end of the warehouse door 26 near the ground. A first ramp 203 and a second ramp 204 are respectively provided on both sides of the threshold 202. The first ramp 203 is fixedly installed on the ground outside the warehouse body 2, and the second ramp 204 is fixedly installed on the warehouse floor.

[0051] In this embodiment, as Figure 8 As shown, a 300-500mm high anti-leakage threshold 202 is set, and a first ramp 203 and a second ramp 204 are set on both sides of the threshold 202 to prevent the liquid in the waste liquid drum from flowing out of the warehouse and to collect the waste liquid in the warehouse body 2.

[0052] In a further preferred embodiment of this utility model, an air purification room 27 is provided on one side of the warehouse body 2 for installing air purification equipment.

[0053] In this embodiment, some toxic and harmful materials will be stored in the warehouse. These materials will release toxic, harmful, and irritating gases. Therefore, an air purification room 27 is set up on one side inside or one side outside the warehouse body 2. Air purification equipment is installed in the room to collect and treat the waste gas in the warehouse before discharging it, and to deliver clean and harmless air into the warehouse.

[0054] The method of using a hazardous waste warehouse according to this utility model is as follows:

[0055] During snow removal, the linear drive mechanism 3 drives the heat collection hood 5 and its inner heating rod 4 to reciprocate on the explosion-proof roof 1. During the reciprocating movement, the heating rod 4 is energized and heated. The heat collection hood 5 confines the heat emitted by the heating rod 4. The fan 41 is energized and blows air, directing the heat from the opening of the heat collection hood 5 onto the explosion-proof roof 1, continuously melting the snow falling on the explosion-proof roof 1. During the use of this hazardous waste warehouse, the temperature sensor 37 continuously monitors the indoor temperature. When the indoor temperature is higher than the set temperature, the controller 38 immediately starts the refrigeration equipment 35 to cool the interior of the warehouse body 2 until the temperature reaches the standard value. Only then will the controller 38 stop the operation of the refrigeration equipment 35. This ensures that the indoor temperature is at the optimal level, preventing the deterioration of waste and the generation of exhaust gases, which is beneficial for the storage of hazardous waste.
