At present, pyrosim fire simulation software is mostly adopted for the study of smoke discharge, and the influence of smoke discharge on smoke flow diffusion at different levels on indoor pedestrian streets is achieved. While less research is directed to hardware, it is largely compared and used with existing products or existing technologies offered by suppliers.
CN115235021a discloses an indoor fire-fighting smoke discharging system based on intelligent monitoring, which grabs the condition that the power of a fan is limited and smoke outlets are dispersed in an original smoke discharging channel of an indoor pedestrian street, and achieves the effect of regional concentrated smoke discharging by adding an independent smoke discharging system and a blocking mechanism.
However, the following problems are found in the actual test process, 1, various accessories including the core accessory choke mechanism are non-standard accessories, and if the large-area popularization is not possible, the application cost is high. 2, in general, indoor smoke is diffused outwards in a short-time coverage area under the condition of insufficient smoke discharging capability or large fire; the pair of the smoke detectors can generate the multi-point smoke detector to detect smoke and release the choke mechanism in the actual use process of the technology, so that the number of the opened smoke outlets is large, and the same problems of the original smoke discharging channel are finally reproduced. And 3, only one fan is arranged on the key accessory, so that the problem that smoke cannot be discharged due to fire or probability faults cannot be solved.
CN113531730a discloses a dynamic smoke discharging system and method for a subway parking train inspection warehouse, which is characterized in that smoke discharging units are arranged in a large area, the smoke discharging units are connected in series and parallel to form a smoke discharging system, and when any smoke discharging unit monitors smoke, smoke discharging operation is carried out by the smoke discharging units comprising monitoring points and four surrounding directions, so that the smoke discharging effect is improved; meanwhile, based on the principle, when smoke is diffused, smoke discharging units which are diffused to the smoke discharging units are all used for discharging smoke, and the whole principle is similar to a mine sweeping game. However, the principle is directly applied to indoor pedestrian streets, two major problems exist, 1 cost is high, smoke alarm and smoke exhaust pipelines are paved on all shops, the construction difficulty is high, even if the pipelines directly adopt the original smoke exhaust channels, the equipment added later and the transformation cost are huge, and even if the novel pedestrian streets are constructed, the problem of high equipment purchase cost also exists. 2 has limited effect, the indoor pedestrian street mainly considers atrium smoke discharge, ring corridor smoke discharge and room smoke discharge, if the dynamic smoke discharge system of the subway parking train checking warehouse is applied to ring corridor smoke discharge, the effect is good, but if the system is used for room smoke discharge, one room generates smoke due to the space isolation state among all rooms, and other rooms are not helpful even if the smoke discharge is started.

Detailed Description
The invention is described in detail below with reference to the accompanying drawings:
as shown in fig. 1-6: the intelligent joint defense fire-fighting smoke-discharging system for the indoor pedestrian streets is arranged in a circular corridor area or a room area of the indoor pedestrian streets;
Comprises a smoke exhaust pipeline 1, a control device, a smoke detector 2, a smoke exhaust air pipe 3, a normally open air valve 4 and a fan 5;
The annular corridor area or the room area is divided or selected to form at least one joint defense partition 7 for independently exhausting smoke, and any joint defense partition 7 is divided into a plurality of adjacent smoke exhausting partitions 8;
the top of any smoke discharging partition 8 of the joint defense partition 7 is provided with a smoke discharging pipeline 1, a plurality of smoke discharging ports are arranged on the smoke discharging pipeline 1, and a smoke detector 2 electrically connected with a control device is also arranged on the smoke discharging partition 8;
Any smoke exhaust partition 8 of the joint defense partition 7 is provided with a fan 5, and the fans 5 are respectively provided with a smoke exhaust air pipe 3 correspondingly; the smoke exhaust air pipe 3 is provided with a branch circuit, so that the smoke exhaust air pipe 3 forms a plurality of air inlets, the number of the air inlets is equal to that of the smoke exhaust partitions 8 of the joint defense partition 7, and the plurality of air inlets are respectively connected with the smoke exhaust pipelines 1 of each smoke exhaust partition 8 under the joint defense partition 7;
the exhaust port of the exhaust air pipe 3 is connected to an original exhaust air channel 91 near the exhaust partition 8; the fan 5 is arranged at the exhaust port of the corresponding smoke exhaust air pipe 3;
The air inlet of any smoke exhaust air pipe 3 is provided with a normally open air valve 4, and the normally open air valve 4 is electrically connected with a control device.
Generally, indoor pedestrian streets have clear plans, namely, a specific area is used as catering, the specific area is used as clothing for sale, and whether installation is carried out or not can be determined according to the specific of the using area.
It should be noted that, the room area mentioned here does not necessarily refer to an independent room, but may be a large space that is visually divided by a fireproof plate and a fireproof curtain to form a plurality of areas, and each area may form a smoke exhaust partition. Visually, the decoration can be performed by painting the smoke exhaust duct.
The plurality of smoke outlets on the smoke exhaust pipeline can be arranged on the side surface of the smoke exhaust pipeline or on the bottom surface of the smoke exhaust pipeline.
The invention has the difference with a plurality of smoke discharging systems that a normally open air valve 4 is arranged at the air inlet of any smoke discharging air pipe 3, namely, the normally open air valve is in an open state in a normal state, so that two points are mainly considered in design, and the situation that the valve cannot work due to failure and other reasons in the fire disaster process can be avoided; on the other hand, under the condition that the valve is kept normally open and the fan is started, the invention can mention the function of the fresh air system, and for some merchants with higher requirements on air quality, the fresh air system can be replaced by installing the invention, and the functions of daily use and fire-fighting smoke discharging are simultaneously completed through single payment.
Of course, the rotation speed of the fire-fighting fan is generally higher, and if the fire-fighting fan is started at full speed, larger noise is generated, so that when the fire-fighting fan is used as a fresh air system, the noise can be reduced by adjusting the rotation speed of the fan.
In addition, the exhaust port of the fume exhaust air pipe 3 is directly connected into the original fume exhaust channel 91, so that the difficulty of transformation is reduced, the damage to the existing decoration of a merchant is reduced, and the merchant is prevented from breeding contradicting emotion.
The smoke exhaust pipeline 1, the control device, the smoke detector 2, the smoke exhaust air pipe 3, the normally open air valve 4 and the fan 5 are all mentioned in the invention; the air conditioner is a standard accessory, wherein the control device adopts a PLC intelligent controller, the fan needs to select proper power according to the situation, and other air pipes, smoke exhaust pipelines, smoke detectors and normally open air valves can be directly purchased to obtain qualified products. The method has the characteristics of low reconstruction cost and the like, is easy to popularize and use in a large area, and can further reduce the cost by batch purchasing.
As shown in fig. 1-5: for the purpose of explanation, the invention designs four smoke discharging partitions which are respectively divided by ABCD, and the equipment corresponding to each smoke discharging partition, such as a normally open air valve, a fan, a smoke discharging pipeline, a smoke discharging air pipe and the like, is also divided by ABCD. (in the figure, letters are remarked on different smoke exhaust pipelines, and the smoke exhaust pipeline 1 is thickened)
The smoke exhaust partition A is provided with a smoke exhaust pipeline A, meanwhile, a fan A is also arranged in the smoke exhaust partition A, and the smoke exhaust air pipes A are respectively connected with the smoke exhaust pipelines B, C, D through branch pipes; the layout of smoke exhaust section B, C, D refers to smoke exhaust section a. Since the smoke exhaust partition a is provided with the air outlet 92 of the original smoke exhaust channel 91, the connection between the smoke exhaust channel a and the air inlet a is closer to the air outlet 91 than the connection between the smoke exhaust channel a and the air inlet B, C, D.
When a fire disaster occurs in the smoke discharging partition A, the smoke detector of the smoke discharging partition A senses smoke and feeds the smoke back to the control device, the control device controls the normally open air valve A, B, C, D except the smoke discharging pipeline A to be closed, and simultaneously controls the fan A, B, C, D to be started in a full power mode, so that smoke discharging of the smoke discharging partition A is realized.
The original smoke exhaust channel 91 is provided with at least one air outlet 92 in the smoke exhaust partition 8, and the smoke exhaust duct 1 of the smoke exhaust partition 8 is correspondingly connected with the smoke exhaust duct 3 corresponding to the air inlet closest to the air outlet 92 among the plurality of air inlets, which is the smoke exhaust duct 3 corresponding to the fan 5 in the smoke exhaust partition 8.
When the smoke discharging partition A is in a fire disaster, the fan and the normally open air valve 4 are more likely to fail and cannot be used. This results in a poor (not completely ineffective) adsorption of the vicinity of the junction of exhaust duct a with intake port a, as intake port B, C, D still acts on this region, while the adsorption of the vicinity of the junction of exhaust duct a with intake port B, C, D is stronger. However, the exhaust port 91 of the original exhaust duct 91 generally does not fail, so the exhaust port 91 compensates for the defect of poor adsorption effect in the vicinity of the junction between the exhaust duct a and the intake port a. Thereby ensuring that the suction forces in each area of the smoke exhaust duct A are balanced. It should be noted that, since the exhaust port 92 of the original smoke exhaust channel 91 is not necessarily matched with the air inlet, the position of the air inlet a or the exhaust port 92 may be properly adjusted during actual operation.
In order to reduce damage of the fan caused by heat and prolong the working time of the fan, the fan 5 adopts a high-temperature-resistant fan 5.
The smoke detector 2 is mounted in the middle region of the smoke evacuation partition 8. In general, smoke will rise thermally after firing and start to spread all around after contacting the roof, and because the smoke discharging partition is divided by the fireproof plate and the fireproof curtain at the top of the smoke discharging partition, the smoke stops spreading after contacting the fireproof plate until the temperature is reduced or the accumulated smoke exceeds a threshold value to bypass the fireproof plate. So that the smoke detector 2 can easily detect the corresponding fire condition as soon as the fire is on, and a plurality of groups of smoke detectors 2 can be arranged in one smoke discharging partition 8 according to the actual requirement to improve the detection sensitivity.
The invention mainly aims at mechanically exhausting smoke in the circular corridor area and mechanically exhausting smoke in the room area; the former has the characteristic of high spreading speed of smoke, and the latter has the characteristic that the smoke is easy to accumulate to reach the deadly concentration.
The present invention adopts the following two layouts according to the gallery area and the room area.
Example 1
As shown in fig. 1-3: mechanical smoke evacuation is performed for room areas:
The joint defense partition 7 is located in a room area, a single room or a room in the room area is separated by a fireproof plate to form an independent space to form a smoke exhaust partition 8, four smoke exhaust partitions 8 are arranged, and the central connecting line of the four smoke exhaust partitions 8 is quadrilateral;
the smoke exhaust pipeline 1 positioned in the smoke exhaust partition 8 presents a quadrilateral; the smoke exhaust air pipes 3 are provided with four, and the midpoints of the four sides of the smoke exhaust pipeline 1 are respectively connected with an air inlet of the smoke exhaust air pipe 3.
Generally, although the plan view of a large-area storefront is not regular, the internal space can be divided according to the trend of the beams, and the internal space is divided by fireproof plates to form independent spaces to form smoke discharging partitions. If the store has been divided into cubicles, four rooms may be selected to collectively make up the joint defence partition.
Generally, the divided smoke exhaust partitions 8 are in a shape of Chinese character 'tian', so that when the smoke exhaust air pipes are arranged, two groups of smoke exhaust air pipes are arranged in an I-shaped staggered manner, and the other two groups of smoke exhaust air pipes are arranged in an H-shaped staggered manner, so that the connection of four smoke exhaust partitions is completed.
It should be noted that the present invention is particularly suitable for the reconstruction of room areas, mainly because the room areas are more compact in layout and the smoke discharging effect of the single smoke discharging partition 8 is good. Is particularly suitable for small clothing stores (more compact layout), restaurant stores (open fire) and other rooms with fire-fighting requirements.
Example 2
As shown in fig. 4 and 5: mechanical smoke evacuation is carried out for the circular corridor area:
the joint defense partition 7 is positioned in a circular corridor area, the circular corridor area is divided into a plurality of sections of continuous sections, each section forms a smoke exhaust partition 8, and the smoke exhaust partitions 8 are provided with four smoke exhaust sections which are linearly arranged;
the smoke exhaust pipeline 1 positioned in the smoke exhaust partition 8 is H-shaped formed by two longitudinal sections and one transverse section; the transverse section divides the two longitudinal sections into four sub-pipelines, the smoke exhaust air pipe 3 is provided with four sub-pipelines, and the middle points of the four sub-pipelines are respectively connected with the air inlet of the smoke exhaust air pipe 3.
Because arbitrary exhaust pipe 1 is H and cuts apart and form four subducting, that is to say arbitrary exhaust pipe can both connect two air inlets in the ring corridor both sides. In the figure, the left upper corner subducting of the four smoke exhaust ducts is connected with the air inlet of the first smoke exhaust duct 3, and the left lower corner subducting is connected with the air inlet of the second smoke exhaust duct 3; the right upper corner subducting is connected with the air inlet of the third smoke discharging air duct 3, and the right lower corner subducting is connected with the air inlet of the fourth smoke discharging air duct 3.
It should be noted that, compared with the transformation of a room area, because the annular corridor area is a channel structure, the method can only be transformed for a key section, if the annular corridor area needs full-section transformation, the cost of the method is relatively high, the pipeline layout is relatively complex, and instead, the scheme disclosed by the CN113531730A is more suitable for the full-section transformation of the annular corridor area.
It should be noted that the foregoing description is only a preferred embodiment of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood that modifications, equivalents, improvements and modifications to the technical solution described in the foregoing embodiments may occur to those skilled in the art, and all modifications, equivalents, and improvements are intended to be included within the spirit and principle of the present invention.
