Description
Technical field
The utility model relates to the pretreatment of dust, is specifically related to dust preprocessing device.
Background technology
Existing cleaner mainly comprises mechanical collector, wet scrubber, sack cleaner and electrostatic precipitator etc.Mechanical collector should, dust that particle thick large for the treatment of concentration, but processing accuracy is low, be used alone and be difficult to satisfy the demands, wet scrubber, sack cleaner and electrostatic precipitator processing accuracy are high, but higher for Inlet dust concentration, humidity requirement, dust preprocessing device must be set up before filtration, purification.And existing dust preprocessing device mainly mechanical collector, its operation principle is: by gravity or inertia, dust is separated from air-flow, but single mechanical collector does entrance concentration, humidity requirement that pretreatment unit is generally difficult to reach next stage deduster, sometimes even need several and use, so just considerably increase cost, and the general volume of mechanical collector is larger, take up room, in addition, mechanical collector is by himself structure influence, and the pretreating effect for high concentration, high humility dust is limited.
As can be seen here, there is the problem of dust removing effects difference in current fine dust pre-processor.
Utility model content
Technical problem to be solved in the utility model is the problem that current fine dust pre-processor exists dust removing effects difference.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts there is provided a kind of dust preprocessing device, comprises dust passage and dust hopper;
Described dust passage is in the shape of the letter V, and the outside horizontal-extending of arranged on left and right sides forms air inlet and gas outlet respectively, and described dust hopper connects with the lowermost end of described dust passage, and the length direction along described dust passage inner chamber is provided with deflection plate assembly.
In above-mentioned dust preprocessing device, described dust passage is bolted by upper and lower two housings.
In above-mentioned dust preprocessing device, described deflection plate assembly comprises the multiple deflection plates arranged along dust passage width side by side parallel.
In above-mentioned dust preprocessing device, the downward projection of described deflection plate is sinusoidal, and described sinusoidal highs and lows is respectively equipped with flow blocking piece, and described flow blocking piece protrudes towards described air inlet direction.
In above-mentioned dust preprocessing device, described dust passage is also provided with radiating fin.
In above-mentioned dust preprocessing device, described dust hopper is inverted cone shape.
Dust passage is designed to V-shaped by the utility model, dust hopper is arranged on the least significant end of dust passage, after gas enters dust passage, big dust particle, steam and downward-sloping passage produce and collide and fall fast, the impurity only having particle less just can be mixed in gas through acclivitous passage, finally discharge from gas outlet, the dust that in rising passway, particle is larger can sedimentation gradually, and the deflection plate assembly in dust passage more serves stiffening effect, deflection plate has outstanding effect to the liquid in gas and dust process, be particularly useful for high concentration, the pretreatment of high humility dust, equipment is small and exquisite, simple installation, treating capacity is large, energy-saving safe, there is higher dust clearance, practical.

Detailed description of the invention
The utility model provides a kind of dust preprocessing device, and structure is simple, and dust clearance is high.Below in conjunction with specific embodiment and Figure of description, the utility model is described in detail.
As depicted in figs. 1 and 2, the dust preprocessing device that the utility model provides comprises V-shaped shell 1 and deflection plate assembly 2, V-shaped shell 1 comprises upper body 4, lower case 6 and dust hopper 3, upper body 4 and lower case 6 form dust passage, and the outside horizontal-extending of arranged on left and right sides forms air inlet and gas outlet respectively, dust hopper 3 connects with the lowermost end of dust passage, and the length direction along the inner chamber of dust passage is provided with deflection plate assembly 2.
Upper body 4 and lower case 6 are fixed by multiple fastening bolt 5, are convenient to dismounting, easily check and change the inefficacy plate in deflection plate assembly 2.
Composition graphs 1, Fig. 3, deflection plate assembly 2 is made up of multiple deflection plate 7, and each deflection plate 7 arranges according to a determining deviation, and be arranged in parallel along the width of dust passage.In the present embodiment, the downward projection of deflection plate 7 is sinusoidal, and is respectively equipped with flow blocking piece 8 at sinusoidal highs and lows, and flow blocking piece 8 protrudes towards the direction of air inlet, and flow blocking piece 8 interval is arranged, and can adjust the quantity of flow blocking piece 8 as required.After gas enters dust passage, due to the inertial impaction effect of gas, the steam taken out of in gas and deflection plate 7 collide and are attached in its surface, and form larger drop gradually, until the drop gathered arrive greatly climbing power that the gravity that himself produces exceedes gas and surface tension of liquid with joint efforts time, drop just gets off from deflection plate 7 is separated on the surface, and big dust particle also together can be blocked along with drop, and flow blocking piece 8 can play stiffening effect.
Flue-dust retainer 3 is inverted cone shape, and the dust after sedimentation and steam are more easily discharged.
On the basis of above-described embodiment, radiating fin can also be set up in dust passage, make it can process high-temperature dust.
Be specific works principle of the present utility model below:
The dust air-flow of high concentration, high humility is entered by air inlet, by the continuous print S shape structure in deflection plate assembly 2, dust and steam constantly collide the sidewall of deflection plate 7, there is sedimentation and cohesion under gravity, big dust particle, steam and downward-sloping passage produce and collide and fall fast, the impurity only having particle less just can be mixed in gas through acclivitous passage, finally discharge from gas outlet, can sedimentation gradually at the larger dust of rising passway particle, dust after sedimentation and steam enter flue-dust retainer 3, complete whole preprocessing process.
The utility model, be particularly useful for the pretreatment of high concentration, high humility dust, equipment is small and exquisite, simple installation, and treating capacity is large, and energy-saving safe, has higher dust clearance, practical.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
