The utility model discloses the water yield consumes for a short time, and is low to the cleanliness factor requirement of water, can save the water resource, reduce cost.

Description

Foam sparger is used in a kind of depositing dust fire extinguishing
Technical field
The utility model relates to a kind of depositing dust fire extinguishing foam sparger.
Background technology
The mode that current depositing dust fire extinguishing generally adopts high pressure water to be sprayed by shower nozzle, which water consumption is large, and shower nozzle easily blocks, high to the purity requirements of water, for our serious deficient water resource, saves each and drips all extremely important.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of depositing dust fire extinguishing foam sparger.
For solving the problem, technical solution adopted in the utility model is:
Foam sparger is used in a kind of depositing dust fire extinguishing, its key technology is: it comprises cylindrical shell, the rear and front end of described cylindrical shell is respectively arranged with inlet and foam outlet, the middle part of cylindrical shell is provided with dividing plate and the inner chamber of cylindrical shell is divided into the first chamber and the second chamber, described first chamber internal fixtion is provided with Venturi tube, the entrance point of described Venturi tube is connected with described inlet, port of export correspondence is fixedly installed on the current collector on described dividing plate, described current collector is communicated with the first chamber and the second chamber, the sidewall of described first chamber is provided with air inlet, air inlet chamber is formed between described cylindrical shell and Venturi tube, described air inlet and described air inlet chamber, trunnion the second half sidewall of described Venturi tube is provided with some small air inlet holes, described small air inlet hole is communicated with described air inlet by described air inlet chamber.
As further improvement of the utility model, the second described chamber internal fixtion is provided with multiple tactic annulus spoiler.
The beneficial effect adopting technique scheme to produce is:
The utility model structure is simple, utilize Venturi tube that the liquid containing blowing agent can be made to be converted into flow at high speed by low speeds flow, be converted into low speeds flow state again, the change of high-low pressure difference, with enter into pressed gas by air inlet and be mixed to form bubble, fast and effectively liquid can be carried out foaming process, play depositing dust extinguishing effect.The utility model water content consumption is little, low to the purity requirements of water, can save water resource, reduce costs.
The bubble of generation fully can be stirred again by the effect arranging annulus spoiler allows gas-liquid mixed form more bubble.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 inlet, 2 connecting bolts, 3 Venturi tubes, 4 cylindrical shells, 5 air inlets, 6 small air inlet holes, 7 current collectors, 8 annulus spoilers, 9 foam outlets, 10 first chambers, 11 dividing plates, 12 second chambers.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 and specific embodiment, utility model is described in further detail:
A kind of depositing dust fire extinguishing foam sparger as shown in Figure 1, it comprises cylindrical shell 4, the rear and front end of described cylindrical shell 4 is respectively arranged with inlet 1 and foam outlet 9, and the middle part of cylindrical shell 4 is provided with dividing plate 11 and the inner chamber of cylindrical shell 4 is divided into the first chamber 10 and the second chamber 12.In the present embodiment, described cylindrical shell 4 comprises two parts, and first half cylindrical shell and later half cylindrical shell, be fixedly connected with by connecting bolt 2 between first half cylindrical shell and later half cylindrical shell, be provided with dividing plate 11 between first half cylindrical shell and later half cylindrical shell respectively.
Described first chamber 10 internal fixtion is provided with Venturi tube 3, the entrance point of described Venturi tube 3 is connected with described inlet 1, port of export correspondence is fixedly installed on the current collector 7 on described dividing plate 11, described current collector 7 is communicated with the first chamber 10 and the second chamber 12, the sidewall of described first chamber 10 is provided with air inlet 5, air inlet chamber is formed between described cylindrical shell 4 and Venturi tube 3, described air inlet 5 and described air inlet chamber, trunnion the second half sidewall of described Venturi tube 3 is provided with some small air inlet holes 6, described small air inlet hole 6 is communicated with described air inlet 5 by described air inlet chamber.The second described chamber 12 internal fixtion is provided with multiple tactic annulus spoiler 8.
The course of work of the present utility model is as follows: the pressure fluid containing blowing agent enters into Venturi tube 3 by inlet 1, be ejected in current collector 7, compressed air enters in cylindrical shell 4 by air inlet 5, then mixed with the pressure fluid containing blowing agent to entering into current collector 7 by small air inlet hole 6, liquid containing blowing agent is converted into flow at high speed by low speeds flow, be converted into low speeds flow state again, the change of high-low pressure difference, with enter into pressed gas by air inlet and be mixed to form bubble, the bubble generated fully stirs through annulus spoiler 8 again and allows gas-liquid mixed form more bubble, the foam formed is sprayed by foam outlet 9.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in previous embodiment, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the utility model embodiment technical scheme.
