Description

Heavy oil is pulverized mulser

Technical field

The utility model relates to a kind of mechanical heavy oil that is used for heavy oil or fuel oil such as residual oil, pitch and pulverizes mulser.

Background technology

Heavy oil is the common fuel of steel plant, glass factory etc., and viscosity is big, flowability is poor, impurity is many, and contains certain moisture.Without the heavy oil of pulverizing emulsification, because well cuts easily precipitates, oily capsule particle is big, so the not good and easy coking and blocking in nozzle place of atomizing effect when burning; Uneven moisture can cause flame pulsation even burner hearth to stop working, and causes furnace temperature fluctuation, causes the instability of product quality.

In Chinese patent CN98223824.X, disclose a kind of efficient wet and disperseed pulverizer, it comprises one group of housing by motor-operated rotor and containing rotor; Charging aperture and discharging opening are arranged on the housing; 1～4 rotating disk is arranged on the rotor, 1～4 milled ring is arranged on the rotating disk; Each rotating disk has corresponding milled ring to a stator being arranged every dish on dish.But this machine is applicable to and disperses to pulverize the solidliquid mixture material; for pulverizing emulsification heavy oil; because the viscosity of heavy oil is big, seal request is high, operating temperature even up to more than 200 ℃ and must do not shut down continuous operation in 24 hours/day, so efficient wet dispersion pulverizer obviously can not adapt to above-mentioned working condition.

Summary of the invention

In order to solve the deficiency that above-mentioned efficient wet disperses pulverizer, the utility model provides a kind of improved heavy oil pulverizing mulser that is used to pulverize emulsification heavy oil.This machine adopts 1～6 to pulverize the emulsion chamber, can fully pulverize emulsification heavy oil, thus help the thorough spray burning of heavy oil, furnace temperature stable, save fuel oil, reduce and pollute.

The utility model is achieved in that the utility model heavy oil pulverizing mulser comprises support, settle motor and bearing block on the support, settle motor and bearing block on the support, main shaft and the rotor of main shaft drive and the stator that matches with rotor by bearings are housed on the bearing block, rotor is contained by the housing that is fixed on the bearing block, charging aperture and discharging opening are housed on the housing, bearing and housing are fixed on the bearing block that has cooling structure, each rotor and the stator that matches are formed one is changeed stator pack, 1～4 milled ring is respectively arranged on each rotor and the stator, each changes stator pack and corresponding housing is formed a pulverizing emulsion chamber, described heavy oil is pulverized mulser and is provided with 1～6 pulverizing emulsion chamber, each axial distance that changes stator pack rotor and stator is 0.4～1mm, and radial clearance is 0.1～1mm.Its operation principle is: High Temperature and Heavy Oil enters the first order from charging aperture and pulverizes the emulsion chamber, connect successively again by later pulverizing at different levels emulsion chamber, because running up of rotor, order about material and in the close clearance of rotor and stator, produce the high frequency turbulence, form the high-velocity fluid shearing force of band impulsive force greatly, oily capsule in the heavy oil and the moisture in solid particle and the heavy oil are subjected to the acting in conjunction of at a high speed shearing, centrifugal extruding, bump and grinding and by pulverizing, dispersion, fully emulsified, material is discharged by discharging opening for several times after repeating to pulverize emulsification.

The utility model has 6～16 blades (being called back blade) near rotor (the promptly last level rotor) back side of discharging opening, to increase the discharging lift, solves the transportation problem of high viscosity material.

Between the utility model housing and the bearing sealing device is housed; to prevent material from leakage; the sealing device is the notopodium face; accessory impeller; parts such as accessory impeller cavity and mechanical seal are formed; back blade; accessory impeller; end play between the accessory impeller cavity is 0.1～1mm; back blade in the sealing device; accessory impeller; the combination of parts such as accessory impeller cavity is called movable sealing again; promptly when machine run, seal; can not shut down again under the situation of maintenance service life even surpass mechanical seal, also can guarantee the operation of equipment long-time continuous and material from leakage does not take place at operation hours.

Rotor of the present utility model and stator material are stainless steel or structural alloy steel, and through Overheating Treatment with increase the surface hardness and mechanical strength.

Bearing block of the present utility model is provided with cooling water inlet pipe and cooling water outlet pipe and 24 hour/day does not shut down continous-stable running in temperature under up to working condition more than 200 ℃ to guarantee material.

The utility model heavy oil is pulverized mulser and is compared with prior art had following tangible advantage:

1, bearing cooling system support equipment of the present utility model was not shut down the continous-stable operation in temperature in 24 hours/day under up to working condition more than 200 ℃;

2, sealing device of the present utility model is guaranteed the leakage of equipment long-time continuous operation nothing, and can be born the fluctuation of the fierceness between material pressure 0～1.0Mpa scope in the pipeline system, and solved the transportation problem of very high viscosity material, and is stable;

3, profile of tooth, quantity, size and the fit clearance of the milled ring in the utility model rotor stator group can be adjusted flexibly according to different oil products and requirement.
