Description
The utility model relates to the device that gas is separated with solid particle with wind-force, is meant a kind of efficient cyclone separator that sprays discharging structure that has especially.
In the prior art, gas, solid separation and dry method particle recovery system are made up of cyclone separator and coupled removal device.The air-flow that has solid particle tangentially enters the cyclone separator body.Form inside and outside two-layer eddy flow therein, solid particle is split into skin under action of centrifugal force.Fall into ash bucket, reclaimed through discharge nozzle and removal device discharge again.And gas flows to the internal layer low-pressure area, discharges through the blast pipe that is positioned at the top axis part.Existing studies show that, the lock gas discharge performance of cyclone separator bottom discharging device is very big to the separative efficiency influence.If inleakage is total 5% of tolerance of handling, then separative efficiency descends 50%; If inleakage reaches at 15% o'clock, separative efficiency can drop to zero.This shows removal device air locking important.Experiment also shows, bleeds on a small quantity from discharge nozzle and can reduce the solid content of exhaust outlet significantly.The removal device of at present domestic and international existing common cyclone separator, as 7 kinds of contained dry method removal devices of " cleaner design " 426-439 page or leaf that Chemical Equipment Design pandect editorial board compilation, Science and Technology of Shanghai publishing house published in 1985, do not possess and realize lock gas discharge and the function of bleeding on a small quantity simultaneously.
The purpose of this utility model is to provide a kind of and can " locks gas " and can realize the efficient cyclone separator that sprays discharging structure that has of bleeding on a small quantity from discharge nozzle again, and it can improve gas and solid particle separative efficiency effectively.
The utility model provides have spray discharging structure efficient cyclone separator as shown in Figure 1, ash bucket (4) by separator body (3) and below thereof, the discharge nozzle (5) of ash bucket (4) below, the removal device (7) and the adjusting control module (6) of discharge nozzle (5) below are formed, and discharge nozzle (5) connects as one with removal device (7).For example adopt the flange connection of welding or having sealing gasket.Secondly, at removal device (7) one ends 1-5 nozzle (8) is installed, the outlet pipe of the control valve (61) in the place, gas access of this nozzle (8) and the adjusting control module (6) communicates;
Connect a upward pressure sensor (9) on discharge nozzle (5) wall, connect a lower pressure sensor (10) on removal device (7) wall.Upward pressure sensor (9), lower pressure sensor (10) are connected with adjustment control (62) in regulating control module (6) by the pressure measurement lead respectively.
The above-mentioned height that has the efficient cyclone separator that sprays discharging structure, i.e. upper limb from separator body (3) upper surface to discharge nozzle (5), the ratio of the interior diameter D of this height H and separator body (3) cylindrical section is H/D=4.5-5.5.This optimum value obtains through the computer optimization design.Adopt above technical scheme can guarantee high efficiency of the present utility model.
Operation principle of the present utility model is:
The air-flow that contains solid at first enters a works (1) that is known as inertia separator, to remove bulk particle and foreign material, enters cyclone separator body (3) then and carries out gas solid separation.The gas that is separated is discharged by blast pipe (2).And the solid particle that carries a small amount of gas falls into ash bucket (4), and concentrates to discharge nozzle (5).At this moment, in advance compressed air is sent into nozzle (8) through admission line, control valve (61), outlet pipe, and near the ejection of discharge nozzle below.This compressed air stream can form the solid particle in the discharge nozzle and entrainment effect, and it is entered removal device (7) swimmingly, and discharges from its outlet.So both avoid stagnant material phenomenon, improved separative efficiency again.Adopt a plurality of nozzles can reduce compressed-air actuated consumption, and make and entrainment even action than single-nozzle.This effect of entrainmenting cooperates with high " lock gas " function, and reasonably the H/D value just can make and reaches gas and separating of solid particle desirable effect.For solid particle is in time discharged and few consumption of compressed air, the compressed air that enters nozzle is designed to automatic adjusting.Adjustment control of the present utility model adopts the standard industry single board computer, as 8096; Control valve is an electric control valve, as the Z940H-16C electric gate valve, and the J941H-16C electric check valve, LD941X-16C electric butterfly valve etc., circuit, wiring are undertaken by the requirement of its specification.The signal of telecommunication after upper and lower pressure sensor conversion enters adjustment control (62) and handles.As make upper and lower pressure sensor place that pressure is respectively P

The utility model has the advantages that: owing to adopted above-mentioned three effective measures, and gas, solid separating effect are significantly improved, and it is easy for installation, stable operation, the elasticity of overall separation discharge is big, decapacitation separates outside general gas, the solid mixture, and optimum is handled the gas of poor mobile performance and the mixture of powder, is widely used in the recovery of department's solid particles such as chemical industry, power.
Below by an embodiment embodiment of the present utility model is described further.
In this embodiment, utilize the utility model to replace original rotary valve, to improve gas, solid separative efficiency.Fig. 2 has showed one, and to reclaim diameter be 0.087 millimeter, not only gently but also sticking, and the technological process of mobile very poor MBS plastic grain.Gas, solid material are passed through pipeline (11), (12), (13) by 70 ℃ hot blast, send into two and have in the efficient cyclone separator that sprays discharging structure.For removing bulk particle and foreign material, at first allow supplied materials through inertia separator works (1), carry out inertial separation.The gas that is separated is discharged through deduster (14) and air-introduced machine (15).Plastic grain then enters fluid bed (16) continuation drying through spraying removal device.Dried plastic grain is discharged through side mouth (17), becomes moisture less than 1% qualified products.The gas that has a small amount of fine powder that plastic grain evaporates in fluid bed enters the 3rd through pipeline (18) and has in the efficient cyclone separator that sprays discharging structure, and discharges by air-introduced machine (19) along discharge duct.Present embodiment replaces old rotary valve with the utility model, makes separative efficiency bring up to 99% by original 80%.
