The invention discloses a foam sol foaming device. The foam sol foaming device consists of a liquid inlet pipe, a foam tank, an air compressor, an adjustment valve and an aeration head, wherein the foam tank is a sealed box body; an isolation plate is arranged in the middle of the foam tank to divide the foam tank into a foam generation part and a foam storage part; the liquid inlet pipe enters the foam generation part of the foam tank from the bottom; a foam sol solution is stored in the foam generation part of the foam tank; the aeration head is soaked into the foam sol solution; the air compressor is connected with the aeration head through a pipeline and is provided with the adjustment valve; a foam outlet pipe and an outlet valve are arranged at the bottom of the foam storage part of the foam tank. The foam sol foaming device has the advantages of simple structure, convenience in operation and easiness in implementation; the foam sol solution with high viscosity can be converted into foam; the device is suitable for the prevention of harbor bulk cargo dust, the dust control of the places with large dust yield, such as a cement plant, a thermal power plant, and blasting operation, , building fire fighting, and the fire prevention of ignition points with spontaneous combustion; the device has a very broad application prospect and a great social benefit.

Description

A kind of foam colloidal sol produces bulb apparatus
Technical field
The present invention relates to colliery ancillary service, particularly a kind of foam colloidal sol produces bulb apparatus.
Background technology
Aqueous foam is widely used in coal industry, and the Britain as far back as the fifties in last century is applied to dust prevention and control by aqueous foam at first, and the state such as the U.S., the former Soviet Union, former West Germany, Japan has carried out the research work of this respect in succession subsequently, and has obtained certain achievement.
In China, aqueous foam being applied to coal industry starts late.The eighties, the mechanism of foam dust-removing that the Chen Dong of Shanghai Research Institute of Mei Ke institute has given birth to Primary Study, but due to condition restriction, do not carry out commerical test.Enter after 21 century, China Mining University's Wang De penetrating judgment is beheaded and time in aqueous foam, is added flyash (three-phase froth) and be applied to prevention of mine fire hazard, again aqueous foam is applied to subsequently to coal mine excavation work plane dust prevention and control, has all obtained good effect.
For aqueous foam being applied to produce reality, system bubble equipment is mainly divided into three power (two water pumps and an air compressor) and double dynamical (water pump and an air compressor) system at present.Three dynamical systems mainly adopt injection type foaming mode, utilize water pump to add water, screw pump interpolation blowing agent, air compressor machine interpolation gas as active force, prepare foam.Double dynamical system bubble system is mainly divided into two classes: the one, and net formula foamed system, it utilizes Compressed Gas as active force, by water pump, expanding foam solution is sprayed onto on foam screen, foams; The 2nd, injection type foamed system, it utilizes water pump as active force, and the negative pressure producing by Venturi tube is adsorbed blowing agent in foam maker, by air compressor machine, adds gas, foams.
Aqueous foam technology has played certain positive role when dustproof and fire prevention, but due to the effumability of aqueous foam solution, causes after air-dry losing the effect that suppresses dust and control fire; The surface viscosity of aqueous foam is inadequate in addition, and foams easily break etc.The defect existing for aqueous foam technology, has proposed foam colloidal sol technology.The foam that this technology generates has higher surface viscosity, and has certain non-volatile part, can suppress long-term effectively dust and control coal spontaneous combustion etc.But because foam sol solution surface viscosity is larger, the generating apparatus of aqueous foam solution cannot be produced bubble.
For this technical problem, for foam colloidal sol being applied to more simply, easily to dust, fire control, be necessary to develop a kind of application equipment that produces bubble for foam colloidal sol.
Summary of the invention
The present invention seeks to for above-mentioned existing problems, provide a kind of foam colloidal sol to produce bulb apparatus, this device can change into foam by the larger foam sol solution of viscosity, is applied to dust and the fire control in the fields such as colliery.
Technical scheme of the present invention:
A kind of foam colloidal sol produces bulb apparatus, by feed tube, foam tank, air compressor, control valve and aeration head, formed, foam tank is seal case, the middle part of foam tank is provided with division board foam tank is divided into and produces bubble and storage bubble two parts, feed tube enters the product bubble part of foam tank from bottom, foam sol solution is stored in the product bubble part of foam tank, aeration head is immersed in foam sol solution, air compressor is connected with aeration head by pipeline and is provided with control valve, and the storage bubble part bottom of foam tank is provided with foam outlet pipe and is provided with outlet valve.
Working mechanism of the present invention:
This device utilizes woven hose to add foam sol solution raw material to producing in bubble tank, utilizes air compressor to aeration head air feed, and to foam sol solution, blows equably by the aperture of aeration head, forms foam.Until foam, producing to gather in bubble tank and surpass while producing the minimum baffle plate of bubble tank, foam starts to flow into storage bubble tank, from storage bubble tank by foam delivery to dust and fire control point, reach and suppress dust and fireproof object.
Advantage of the present invention and beneficial effect are:
This apparatus structure is simple, easy to operate, easy to implement, the larger foam sol solution of viscosity can be changed into foam, be applicable to harbour bulk goods dust prevention and control, dust Control and the structural fire protection in the place that the dust-producing amounts such as cement plant, thermal power plant, bursting work are larger and have the fire control of the ignition point of spontaneous combustion, has very wide application prospect and social benefit.
