Abstract
The invention provides a large-air-volume filtration ventilation system for a tunnel rescue vehicle and belongs to a collective protection system in the technical field of fire protection. The large-air-volume filtration ventilation system mainly consists of a fan, a smoke filter, a flow meter, an electric closed valve, a poison filter, a ventilation duct, a control device and the like. When the large-air-volume filtration ventilation system is used, different working modes of the system can be switched through the control device according to pollutant varieties. The smoke filter filters various particulate matter. The poison filter can filter poisonous and hazardous gas or steam and can prevent harmful and polluted gas from being gathered in a tunnel and prevent pollutants in the tunnel from harming persons inside and outside the tunnel so as to facilitate timely rescue and normal passing recovery of the tunnel.
Description
Technical field
The present invention relates to a kind of Collective Protective System for fire prevention field, this system is installed on tunnel relief car, be mainly used in occurring that poisonous and harmful aerosol, chemical substance (comprising organic vapor and gas, sour gas, ammonia and organic derivative thereof) gas (hereinafter to be referred as pollutant) pollute in tunnel time, filter the pollutant in tunnel air, pollutant levels in tunnel are reduced as early as possible, prevent that the pollutant in tunnel from damaging the inside and outside personnel in tunnel, so that rescue is in time normally current with recovery tunnel.
Background technology
The current various fire-fighting and rescue cars of China are not all equipped with Wind Volume and filter ventilation system, in the time carrying out rescue task, can not carry out effectively filtering to remove to the pollutant of the confined spaces such as tunnel in time, may damage treating as a stranger rescue personnel in rescue personnel and tunnel, carrying out smoothly with the timely recovery in tunnel of impact rescue is current.
Summary of the invention
The object of this invention is to provide a kind of special Wind Volume filtration of tunnel relief car ventilation system that can realize to the pollutant in tunnel effectively protection.
The object of the present invention is achieved like this: a kind of tunnel relief car filters ventilation system with Wind Volume
,comprise organism frame, smoke filter is arranged in organism frame, and blower fan is communicated with smoke filter one end by pipeline, and the smoke filter other end is communicated with the first canister, the second canister in parallel; The first canister is connected with air outlet with the second canister, air chimney, is equipped with electric closed valve at the first canister and the second canister two ends, and electric closed valve and blower fan are connected with control device.
On the link road pipe of smoke filter and first and second canister, be provided with flow meter, flow meter is connected with control device.
Described smoke filter is made up of pre-flock unit, essence filter unit, housing, steel ring and inlet and outlet, and He Jinglv unit, pre-flock unit is two absolute construction, is connected as a whole by spinning mode with steel ring with housing, inlet and outlet.
The first canister and the second canister include a multilayer shell, are placed with impregnated carbon in housing.
Tunnel provided by the invention relief car filters ventilation system with Wind Volume, in the time occurring to pollute in tunnel, can be according to the kind of pollutant, and system is changed different operating mode by control device; Smoke filter filters various particles; Canister can filter toxic and harmful or steam, can prevent that harmful and dusty gas from, in tunnel aggregates, preventing that the pollutant in tunnel from damaging the inside and outside personnel in tunnel, so that rescue is in time with to recover tunnel normally current.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is smoke filter structural representation.
Fig. 3 is canister structural representation.
The specific embodiment
Structure of the present invention is as Figure 1-3: a kind of tunnel relief car filters ventilation system with Wind Volume
,comprise organism frame 9, smoke filter 2 is arranged in organism frame 9, and blower fan 1 is communicated with smoke filter 2 one end by pipeline, and smoke filter 2 other ends are communicated with the first canister 5, the second canister 6 in parallel; The first canister 5 is connected with air outlet 17 with the second canister 6, air chimney 7, is equipped with electric closed valve 4 at the first canister 5 and the second canister 6 two ends, and electric closed valve 4 and blower fan 1 are connected with control device 8.
On the link road pipe of smoke filter 2 and first and second canister, be provided with flow meter 3, flow meter is connected with control device 8.
Described smoke filter 2 is made up of pre-flock unit 10, essence filter unit 11, housing 12, steel ring 13 and inlet and outlet 14, pre-flock unit 10 and essence filter unit 11 are two absolute construction, are connected as a whole by spinning mode with steel ring 13 with housing 12, inlet and outlet 14.
The first canister 5 according to claim 1 and the second canister 6 include a multilayer shell 15, are placed with impregnated carbon 16 in housing.
Assembling process of the present invention is:
1, housing 12 is put into in pre-flock unit 10, take on air port 14, its spinning is integrated with steel ring 13, then essence is filtered to unit 11 and put into the other end of housing, take on air port 14, be integrated with steel ring 13 spinning, through being up to the standards, be smoke filter.
2, AE or AK type impregnated carbon are loaded in canister housing 15, sealing medicine containing opening, is the first canister 5 and the second canister 6.
3, smoke filter 2, the first canister 5 and the second canister 6, electric closed valve 4, ventilating duct 7 are arranged on respectively in organism frame 9, then flow meter 3 are installed on ventilating duct.
4, each component controls circuit is connected with control device 8, debugging and by completing after the assay was approved assembling product.Control device 8 is made up of fan frequency converter, PLC, I/O control and communication module and control circuit etc., for the switching of controlling airtight valve work independently to realize the first canister, the second canister works independently and the conversion of three kinds of duties such as simultaneously work of two groups of canisters, and TT&C system air quantity moves under nominal air delivery.
Operating principle of the present invention is as follows: while occurring to pollute in tunnel, according to the kind of pollutant, system is changed different operating mode by control device 8, starts blower fan 1, and the automatic measurement of control device 8 regulating flow are to rated value.Pollutant in tunnel first filters various particles through smoke filter 2, and then air-flow enters first and second canister, filters toxic and harmful or steam.According to working method difference, the kind difference of filtering gas.Filter out various particles, corresponding steam or gas through the air of canister, reached the filtration to air in tunnel.
Protection object of the present invention is extensive, can realize various particles, organic gas or steam, sour gas, ammonia and organic derivative thereof etc. are realized to effectively protection.Barrier propterty is high, and mist of oil filter efficiency is not less than 99.9%; To benzene vapor, sour gas (SO
2), the protection dosage of ammonia is greater than respectively 850mg.min/L, 225 mg.min/L, 90 mg.min/L.Nominal air delivery reaches 5000m
3the two groups of/h(are worked simultaneously) and 2500 m
3mono-group of/h(works alone).
