Abstract
The invention relates to exhaust and dust removal complete equipment for the underground engineering, which comprises an exhaust pipeline part. A gas inlet end and a gas outlet end of the exhaust pipeline part are respectively conducted with an exhaust fan segment and a dust removal discharge segment of which the positions can be moved, a driving part of an exhaust fan is electrically connected with a control port of a controller, and an input port of the controller is connected with a signal port of a sensor, so that fresh gas is ensured to be full filled in an underground operating space, dust gas is conveyed into an exhaust pipeline set by the exhaust fan, is further discharged in a centralized mode after being purified by a dust remover and has no influence on the surrounding environment of an engineering site, and the exhaust and dust removal complete equipment is very environmental-friendly. Meanwhile, the exhaust fan is increased and decreased as required, is automatically stopped and started according to the concentration of the gas and is intelligent and energy-saving.
Description
Technical field
The invention belongs to the mechanical device technical field, be specifically related to a kind of underground construction exhaust dedusting a complete set of equipment.
Background technology
The development and use underground space is the needs of 21 century human survival.The construction speed of underground construction depends on that in a sense site operation produces dust waste gas dissipation speed.That present mechanical ventilation by pipes has is forced, pull-out type and hybrid three kinds.1. forced is with blower fan fresh air to be depressed into work plane through airduct pernicious gas is watered down purification; Less to the explosion influence, but dirty distinguished and admirable from the full section discharge of tunnel, influence other work post operations in the hole; Not only inefficiency, power consumption are huge, and the diffusing cigarette time increases with the hole is long.2. pull-out type is that blower fan is extracted the dirty distinguished and admirable of work plane out along airduct, the full section supply of tunnel fresh air, and flue gas velocity is fast, but airduct end-to-end distance work plane is nearer relatively, is subject to explosion and damages, and be negative pressure in the airduct, pneumatic hose is incompatible.3. hybrid is to be pressed into fresh air with a typhoon machine, and dirty distinguished and admirable draught capacity is strong along the airduct sucking-off with work plane for another typhoon machine, and sanitary condition is good, but wants the above equipment of two covers, and running expense is higher.Up to the present, no matter domestic still external, do not imitate the problem that solves underground construction exhaust dedusting, there is not desirable complete automation equipment yet, further consider that the equipment of environmental protection does not see that more instance is arranged.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists; The object of the present invention is to provide a kind of underground engineering construction exhaust dedusting a complete set of equipment; Not only can effectively purify the job site environment; Characteristics with energy-conserving and environment-protective, and the local dust gas that can also the fast processing explosion produces in time provide the scope of operation of cleaning rock ballast.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of underground construction exhaust dedusting a complete set of equipment; Comprise extract duct branch 1; The inlet end of this extract duct branch 1 and outlet side are conducted with dedusting discharging branch 3 with the exhaust fan branch 2 of ability shift position respectively; 101 groups of the extract ducts that is interconnected with tee junction 102 between described extract duct branch 1 comprises; Exhaust fan branch 2 comprises exhaust fan 201, and the drive part of this exhaust fan 201 is electrically connected with the control port of controller 202, and the input port of controller 202 is with the signal port connection of sensor 203; Described dedusting discharging branch 3 comprises the deduster 301 that the outlet side with extract duct branch 1 is connected, and the outlet of this deduster 301 is conducted with the form of blowdown stack 302 with series connection.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done more detailed explanation.
As shown in Figure 1, underground construction exhaust dedusting a complete set of equipment comprises extract duct branch 1; The inlet end of this extract duct branch 1 and outlet side are conducted with dedusting discharging branch 3 with exhaust fan branch 2 that can the shift position respectively, and be as shown in Figure 2,101 groups of the extract ducts that is interconnected with tee junction 102 between described extract duct branch 1 comprises; As shown in Figure 3, exhaust fan branch 2 comprises exhaust fan 201, and the drive part of this exhaust fan 201 is electrically connected with the control port of controller 202; And the input port of controller 202 is connected with the signal port of sensor 203, so just can adopt the sensing technology testing gas concentration in order to adapt to place dusty gas distribution actual state; Automatically control exhaust fan 201; Reach energy saving purposes, as shown in Figure 4, described dedusting discharging branch 3 comprises the deduster 301 that the outlet side with extract duct branch 1 is connected; The outlet of this deduster 301 is conducted with the form of blowdown stack 302 with series connection; Can avoid dusty gas directly to enter atmosphere like this, adopt the deduster 301 connect with extract duct 101 to purify air, discharge after reaching environmental requirement.
Operating principle of the present invention is: this underground construction exhaust dedusting a complete set of equipment is installed in the underground chamber working space 4; Exhaust fan branch 2 is through sensor 203 testing gas concentrations; The concentration signal of dusty gas is wherein sent to controller 202 in real time; If controller 202 is judged the concentration of dusty gas and is met or exceeded preset concentration limits definite value; Drive exhaust fan 201, and the dust air is entered extract duct branch 1 through tee junction 102, and concentrate discharging through purifying the back through blowdown stack 302 through deduster 301 through the outlet side of extract duct branch 1.
