[0001] The invention relates to the technical field of construction engineering, in particular to a safe storage room for flammable and explosive chemical reagents. Background Art

[0002] A safe storage room for flammable and explosive chemical reagents is a must in chemical laboratories. It stores more than 200 kinds of chemical reagents, most of which are dangerous. For example, more than 100 kinds of flammable and explosive dangerous goods such as anhydrous methanol, ether, and toluene, and nitric acid and sulfuric acid have strong acid and alkali corrosiveness. Therefore, the reagent storage room is a key part of the chemical laboratory's safety hazards.

[0003] At present, there are several situations for chemical reagent storage rooms: (1) Most laboratory buildings are designed as civil buildings, and chemical reagent storage rooms are placed inside the laboratory buildings. In such laboratory buildings designed as civil buildings, there is no provision for the safe location relationship between the chemical reagent storage room and the overall laboratory building, resulting in insufficient safety; (2) A few laboratory buildings are designed as industrial buildings, and the amount of stored chemical reagents and the proportion of the storage room to the fire zone area are controlled. The chemical reagent storage room is placed in the laboratory building, but there is no provision for a safer location and natural ventilation, resulting in insufficient safety; (3) There are also a very small number of separately built flammable and explosive chemical reagent storage rooms, which are independent of the laboratory building and cause inconvenience.

[0004] Judging from the above-mentioned current overall situation, chemical reagent storage rooms with existing technology have various safety hazards at the source of design and construction, resulting in insufficient safety protection technology in subsequent use, which has become one of the important reasons for fire and explosion safety accidents.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] The present invention provides a safe storage room for flammable and explosive chemical reagents, which is arranged in a corner on the north side of the laboratory building. Figure 1 , preferably, the safe storage room for flammable and explosive chemical reagents is arranged in the northwest corner of the laboratory building. The storage room includes explosion-proof walls, fire doors, louver walls, skylights, drainage ditches and floor drains. The louver walls are two adjacent walls connected to the storage room, and the internal space of the storage room is connected to the outdoor space through the louver walls. The explosion-proof walls are the other two adjacent walls connected to the storage room, and the explosion-proof walls are located in the laboratory building, and the internal space of the storage room is isolated from the rest of the internal space of the laboratory building by the explosion-proof walls. The safe storage room for flammable and explosive chemical reagents of the present invention is semi-open, such as Figure 1 As shown, it can form natural convection ventilation similar to a terrace, making it difficult for flammable and explosive gases to accumulate, and in most cases avoid the usual gathering areas of people in the laboratory building.

[0031] See Figure 2 , Figure 2 The structure of a safe storage room for flammable and explosive chemical reagents in certain embodiments is illustrated, wherein the louver wall 5 includes the north wall 51 and the west wall 52 of the storage room. The explosion-proof wall 4 includes the east wall 41 and the south wall 42 of the storage room. The drainage ditch 6 is located on the inner side of the storage room and is arranged along the base of the louver wall. The floor drain 7 is arranged in the northwest corner of the storage room and is located in the drainage ditch, and the floor drain is connected to the drainage pipe. The skylight glass windows 9 are respectively arranged on the north wall 51 and the west wall 52 of the louver wall and the south wall 42 of the explosion-proof wall, and the skylight glass windows 9 are installed with blackout curtains. The fire door 3 is arranged on the south wall 42 of the explosion-proof wall. The reagent cabinet 8 is arranged in the storage room according to actual needs.

[0032] See Figure 3 , Figure 3 The structure of the safe storage room for inflammable and explosive chemical reagents in other embodiments is shown. The area of ​​the storage room is Figure 2 In the illustrated embodiment, the storage room covers half of its area, with daylighting windows 9 located only on the north and west walls of the louvered wall. An isolation room 11 is also located east of the east wall of the explosion-proof wall 4. This structure is suitable for use in environments with limited reagent cabinets, providing an additional layer of protection for the laboratory building.

[0033] The storage room of the present invention has no suspended ceiling, which can prevent the leakage or slight leakage of inflammable and explosive gases from gathering in the suspended ceiling.

[0034] The floor of the storage room of the present invention is a sloped floor, and the floor on the side of the storage room close to the louver wall is lower than the floor on the side close to the firewall. Such a slope is set so that even if there is a very small amount of rain in the storage room, it will be easy to flow into the drainage ditch, and it is also convenient for sewage to be drained into the drainage ditch in time when the storage room is sprinkled with water for cleaning.

[0035] See Figure 4 and Figure 5 The louver wall 5 is equipped with a number of vertically arranged louvers 501. The louvers 501 are made of stainless steel or aluminum alloy. The horizontal cross-section of the louver 501 is S-shaped. The louver 501 is provided with ribs 501a at the recessed positions on both sides of the S-shape. The horizontal cross-section of the ribs 501a is C-shaped. The ribs 501a are used to fix the louver and block rain. Figure 6 As shown, 506 is a crossbeam square tube, which serves as the upper and lower frames of the louver wall. A Z-shaped connector 503 is fixed to the crossbeam square tube 506 via screws 502. The Z-shaped connector 503 has a through hole. A fixing rod 504 is snap-fitted into the C-shaped slot of the rib 501a of the louver plate 501. The upper and lower ends of the fixing rod 504 are provided with external threads. The ends of the fixing rod pass through the through hole of the Z-shaped connector 503 and are secured with nuts 505.

[0036] like Figure 7As shown, the louvers 501 in each louver wall are arranged at equal intervals, and the spacing between the center points of adjacent louvers is set ( Figure 7 k) is smaller than the width of the louver ( Figure 7 shown in m).

[0037] The working principle of the louver wall to block rain is as follows: Figure 7 The figure illustrates four directions of wind and rain: 1) As shown by arrow a, the ribs close to the indoor side block the raindrops blown by the wind and flowing toward the indoor side in the direction of arrow a. After being blocked by the ribs of the louver, the raindrops will flow vertically downward along the outer wall of the ribs. 2) As shown by arrow b, the bulges of two adjacent louvers block the raindrops in the direction of arrow b from entering directly from the outdoor side into the indoor side. 3) As shown by arrow c, the bulges close to the outdoor side of the louver block the raindrops in the direction of arrow c from entering the indoor side. 4) As shown by arrow d, the ribs close to the outdoor side block the raindrops blown by the wind and flowing toward the indoor side in the direction of arrow d. After being blocked by the ribs of the louver, the raindrops will flow vertically downward along the outer wall of the ribs. 5) As shown by arrow e, the bulges close to the indoor side of the louver block the raindrops in the direction of arrow e from entering the indoor side.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
