Description

A kind of sand blasting room is with pneumatic water atomization dust pelletizing system

[technical field]

The utility model relates to a kind of dust pelletizing system, particularly a kind of pneumatic water atomization dust pelletizing system.

[background technology]

Cleaning surfaces for workpiece is handled, than one of more efficient and respond well processing mode is exactly to adopt the technology that sandblasts, for increase work efficiency, working ability and the consideration of saving cost, increasing people selects to set up sand blasting room and carries out the sandblast operation, be exactly the dust removing effects quality of sand blasting room wherein to one of technical evaluation standard of the room most critical that sandblasts, this just need use low cost, and the high deduster of efficiency of dust collection.Deduster is widely used in dust and the flue dust that control has produced.Can be divided into mechanical dust collector, electric cleaner, filter collector and scrubber etc. by capturing mechanism, consider that for cleaner cost consideration and efficiency of dust collection these traditional cleaners are not suitable for requirement high-effective dust-removing and the low-cost sand blasting room cleaner that drops into.

The deduster of prior art mainly is divided into following several: 1, mechanical dust collector, and rely on mechanical force that grit is removed from air-flow, it is simple in structure, and installation cost and running cost are all lower, but efficiency of dust collection is not high; 2, electric cleaner utilizes electrostatic force to realize grit and flow separation, and often by board-like and tubular type classification, characteristics are that gas-flow resistance is little, and efficiency of dust collection can reach more than 99%, but invests higherly, and floor space is bigger; 3, filter collector make dust-contained airflow by filtrate with the grit separation and collection, divide self-filtering and surface filtration dual mode, efficiency of dust collection is generally 90%～99%, and filter needs often to change, and is not suitable for filtration and the high dusty gas of temperature than fine dusts; 4, scrubber washs dusty gas with the atomization of liquid, make grit and drop or liquid film the collision and be captured, and and flow separation, efficiency of dust collection is 80%～95%, the liquid after the sedimentation directly discharges, running expense is higher.

[utility model content]

The technical problems to be solved in the utility model is to provide a kind of sand blasting room with pneumatic water atomization dust pelletizing system, and its cost is low, the efficiency of dust collection height.

The utility model is achieved in that

A kind of sand blasting room of the utility model is with pneumatic water atomization dust pelletizing system, it comprises a cavity, described cavity front end be linked in sequence an admission line, an axial flow blower also are provided with one dust laden air are drained into the air inlet baffle plate of cavity bottom between described cavity and the admission line; Described cavity upper end is provided with an aerosolization spray gun, and described aerosolization spray gun connects an intake chamber, and receives compressed air; Described cavity upper end is provided with an exhaust outlet, and described cavity bottom is provided with a precipitation tank and a dewatering outlet.

Further, a primary efficient filter screen is set in the described admission line, and in the admission line bottom in described primary efficient filter screen the place ahead one opening is set, described opening connects a collection box by a passage.

Further, described intake chamber connects described precipitation tank by a screen pack, and described intake chamber connects a water inlet pipe, and ball float is set and controls the gauge tap that water inlet pipe is intake by the water level of described ball float.

Advantage of the present utility model is: the utility model compared with prior art:

1, of the present utility model simple in structure, only need to open compression gas-pressure, the water of intake chamber can add automatically, opens axial flow blower then dusty gas is sucked, and begins automatic circulation dedusting operation, need not personnel's post;

2, the utility model adopts the aerosolization spray gun, employing compressed air is power, liquid sucked in the spray gun atomize, and be provided with the air inlet baffle plate, increased the time that gas contacts with water smoke, the efficiency of dust collection height can reach 95%, this equipment also adopted make that water can auto recycling intake chamber, saved water resource;

3, the utility model maintaining cleaning is simple, and cheap, and operating cost is low;

4, the utility model also can produce the negative oxygen ion of high concentration in the process of work, and is useful to staff's physical and mental health.

[description of drawings]

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.

Fig. 1 is a structural representation of the present utility model.

[specific embodiment]

See also shown in Figure 1ly, embodiment is described in detail to the utility model.

As shown in Figure 1, the utility model one embodiment, it comprises a cavity 1, and described cavity 1 front end be linked in sequence an admission line 2, an axial flow blower 17 also are provided with one dust laden air drained into the air inlet baffle plate 3 of cavity 1 bottom between described cavity 1 and the admission line 2; One primary efficient filter screen 4 is set in the described admission line 2, and in admission line 2 bottoms in described primary efficient filter screen 4 the place aheads one opening is set, described opening connects a collection box 6 by a passage 5.Described cavity 1 upper end is provided with an aerosolization spray gun 7, and described aerosolization spray gun 7 connects an intake chamber 8, and receives compressed air 9; Upper end, described cavity 1 back is provided with an exhaust outlet 10, and described cavity 1 bottom is provided with a precipitation tank 11 and a dewatering outlet 12.Described intake chamber 8 connects described precipitation tank 11 by a screen pack 13, and described intake chamber 8 connects a water inlet pipe 14, and ball float 15 is set and controls the gauge tap 16 that water inlet pipe 14 is intake by the water level of described ball float 15.

Operation principle of the present utility model is as follows: the dust laden air in the sand blasting room is in the admission line 2 of axial flow blower 17 these equipment of suction, primary efficient filter screen 4 in the admission line 2 filters dirt ash particle bigger in the dust laden air, and natural subsidence is in collection box 6, because just preliminary the filtration, the mesh of primary efficient filter screen 4 is bigger, need not frequent replacing, the preliminary dust laden air that filters of process is under the effect of air inlet baffle plate 3, drain into the bottom of cavity 1, rise to the exhaust outlet 10 of upper end again by the bottom, this has increased the stroke of gas in cavity 1 greatly, has increased the time that gas contacts with water smoke.The aerosolization spray gun 7 of described cavity 1 upper end adopts compressed air 9 as power, in spray gun 7, form relative negative pressure, and by pipeline connection intake chamber 8, liquid is sucked in the spray gun 7, water in spray gun 7 behind high-pressure atomization, along with high pressure draught together sprays,, reach dust removing effects with in the dusty gas in the cavity 1 and absorption.After the water smoke sedimentation, dust granule wherein can slowly be deposited in the bottom of precipitation tank 11, top section water then enters intake chamber 8 through screen pack 13, recycle to continue air feed atomizing lance 7, in the time of this equipment withdraw from service, dewatering outlet 12 can be opened, sewage is emitted, will precipitate tank 11 integral body then and deviate from cleaning.In the described intake chamber 8, when the water level of ball float 15 is lower than the lowest water level of setting, gauge tap 16 will be opened automatically, and water inlet pipe 14 will be intake chamber 8 supplementing water this moment.After highdensity water mist dust-removing filtration, can be by the dedusting efficient of exhaust outlet 10 up to 95%.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
