Description

A kind of production of carbon black K 2cO 3the adding set of solution

Technical field

The utility model relates to a kind of adding set of production of carbon black, particularly relates to a kind of production of carbon black K ₂cO ₃the adding set of solution.

Background technology

At present in Audit For Process manufacturing technologies of carbon black, general employing adds K ₂cO ₃solution controls to adjust carbon black structure, because the structure of different product kind differs greatly, and K needed for it ₂cO ₃the concentration of solution and flow also differ very large, adopt insert separately inclination 5 ~ 10 angle single hole spray gun interpolation K from combustion chamber burner so general ₂cO ₃solution, uses 6kg/cm simultaneously ²the compressed air of pressure is to K ₂cO ₃solution carries out carrying and being atomized, but technique scheme exists following problem: because combustion chamber air inlet interposition is equipped with a fuel oil gun protecting pipe, so K ₂cO ₃solution spray gun need to axial centre tilt 5 ~ 10 ° angle insert, easily cause K ₂cO ₃solution is sprayed onto fuel oil, destroys dispersion and the atomizing effect of fuel oil, is formed and burns insufficient and produce burnt grain impurity, thus directly have influence on the speed of burning and the quality of carbon black; When producing the carbon black products of low structure, the K of high concentration and high flow capacity need be used ₂cO ₃solution carrys out the production of oppressive carbon black structure, although solid-state K before use ₂cO ₃dissolved completely, but single hole spray gun sprays into the K of atomization ₂cO ₃solution concentration is high, before the air inlet of combustion chamber, very easily depend on protecting pipe form crystalline solid, thus reduce the area of combustion chamber air inlet through hollow shaft mouth, change the speed into stove air quantity, make axial wind also disalignment simultaneously, affect fuel oil and the angle entered when stove wind mixes, cause atomizing effect to be deteriorated, make K ₂cO ₃crystal enters combustion chamber, thus reduces the beautiful fusing point of material of combustion chamber chromium steel and the service life of combustion chamber, and cause combustion chamber burner hypertonia time serious, burner vibration is large, even causes producing stopping.

Summary of the invention

The purpose of this utility model is to provide a kind of production of carbon black K ₂cO ₃the adding set of solution, solves existing single hole spray gun and adds K ₂cO ₃during solution, because combustion chamber air inlet interposition is equipped with a fuel oil gun protecting pipe, so K ₂cO ₃solution spray gun need to axial centre tilt 5 ~ 10 ° angle insert, easily cause K ₂cO ₃solution is sprayed onto fuel oil, destroys dispersion and the atomizing effect of fuel oil, is formed and burns insufficient and produce burnt grain impurity, thus directly have influence on the speed of burning and the quality of carbon black; When producing the carbon black products of low structure, the K of high concentration and high flow capacity need be used ₂cO ₃solution carrys out the production of oppressive carbon black structure, although solid-state K before use ₂cO ₃dissolved completely, but single hole spray gun sprays into atomization K ₂cO ₃solution concentration high, before the air inlet of combustion chamber, very easily depend on protecting pipe form crystalline solid, thus reduce the area of combustion chamber air inlet through hollow shaft mouth, change the speed into stove air quantity, make axial wind also disalignment simultaneously, affect fuel oil and the angle entered when stove wind mixes, cause atomizing effect to be deteriorated, make K ₂cO ₃crystal enters combustion chamber, thus reduces the beautiful fusing point of material of combustion chamber chromium steel and the service life of combustion chamber, and cause combustion chamber burner hypertonia time serious, burner vibration is large, even causes producing the problem stopped.

The utility model realizes like this, it comprises compressed air hose, automatic regulating valve, mass flowmenter, fuel oil spray gun, it is characterized in that: the fuel oil medium tube of side, described fuel oil spray gun outer end is from top to bottom successively by compressed air hose quality of connection flowmeter and automatic regulating valve, and the pressure in described compressed air hose is 6kg/cm ², the pressure in described fuel oil medium tube is 2 ~ 4kg/cm ².

Technique effect of the present utility model is: the utility model is by K ₂cO ₃solution by mixing with fuel oil, porous atomization, spray in combustion chamber by fuel oil spray gun with axial 70 angles, and enter the mixed combustion of stove air and evaporate, the high-temperature gas dispersion of formation is better, thus stabilizes production technology and improve product quality, solves K ₂cO ₃solution can not produce wind direction and the wind speed that crystal affects axial wind at entry of combustion chamber place, simultaneously also can not because of K ₂cO ₃crystal enters combustion chamber and reduces the fusing point of refractory material, thus the service life of prolonging combustion room greatly, owing to not using K ₂cO ₃solution spray gun device, the 100Nm3/h that reduces per hour is atomized air supply, thus has saved the effect of production cost, when not having fuel oil as medium, axial fuel oil spray gun can be adopted equally to carry out porous atomization by compressed air, and effect is identical, not by the impact using fuel.

Detailed description of the invention

Composition graphs 1,2 illustrates the utility model, and the fuel oil medium tube of side, described fuel oil spray gun 4 outer end is from top to bottom successively by compressed air hose 1 quality of connection flowmeter 3 and automatic regulating valve 2, and the pressure in described compressed air hose 1 is 6kg/cm ², the pressure in described fuel oil medium tube is 2 ~ 4kg/cm ².

With reference to Fig. 2, insert separately inclination 5-10 angle K owing to adopting from reacting furnace combustion chamber 6 entrance ₂cO ₃solution spray gun 7 adds K ₂cO ₃solution, easily causes K ₂cO ₃solution is sprayed onto fuel oil, destroys dispersion and the atomizing effect of fuel oil, is formed and burns insufficient and produce burnt grain impurity, thus directly have influence on burning

Speed and the quality of carbon black.

With reference to Fig. 1, K ₂cO ₃solution compresses air hose 1 transmits, after automatic regulating valve 2 and mass flowmenter 3, abut against with the fuel oil medium tube on fuel oil spray gun 4, thus mix with fuel oil, after be spray into 70 angles in porch, reacting furnace combustion chamber 6 after the atomization of 4mm spray orifice through six diameters of fuel oil spray gun sheath 5 end sprayer.

Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
