Description
Technical field
The utility model relates to a kind of low-pressure saturated steam and pulverizes the titanium white powder device, belongs to the titanium white production technical field.
Background technology
In rapid economic development, reasonable energy utilization resource and environmental protection are also increasingly important.Titanium white production needs to consume a large amount of steam energies; The post processing of titanium white powder is the titanium white powder bullion of pre-treatment to be covered through thunder pull an oar after pulverizing, carry out surface treatment behind the sand milling; The washing of titanium white powder slurry after the surface treatment with carry out spray-drying after the making beating again, it is broken more dried titanium white powder powdered granule to be carried out micro mist with flat airslide disintegrating mill.On the annular pulverizing chamber cylindrical of flat airslide disintegrating mill, be uniformly distributed with plurality of nozzles, the axis direction of nozzle is cut a circle altogether.Crushing medium is middle pressure superheated steam, and superheated steam sprays into pulverizing chamber at a high speed and forms the vortex flow field after nozzle quickens, when material is sprayed into pulverizing chamber by injection, receive the rolling action particle of gas to do high speed rotary motion thereupon.Because velocity field changes, this makes particle not of uniform size with different speed and direction motion, has just produced collision between particle, the material that rubs is able to pulverizing.When granularity reached certain value, material is taken out of to the air-flow of central motion pulverized the district, gets into blast pipe and discharges as product.The steam that the air-flow of our company is pulverized usefulness is the middle pressure superheated steam of boiler for producing.In the production steam course, consume coal resources, also discharge a large amount of sulfur dioxide, pollutant atmosphere simultaneously.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point; Thereby provide a kind of low-pressure saturated steam to pulverize the titanium white powder device; The low-pressure saturated steam that the power plant is unnecessary becomes the middle pressure superheated steam that low-pressure superheated steam substitutes boiler for producing after with the gas heating furnace heat exchange; Utilize the unnecessary energy, eliminated coal-burning boiler, reduced the discharging of sulfur dioxide.
According to the technical scheme that the utility model provides, low-pressure saturated steam is pulverized the titanium white powder device and is comprised feed bin, material handling spiral, feeding steam pipe before finished product bin behind neat gas burner, air-heating furnace, the powder, hot precipitator, the powder, pulverizes steam pipe, heat-exchanging chamber and flat airslide disintegrating mill.
Said air heat stokehold connects neat gas burner, is provided with heat-exchanging chamber in the air-heating furnace.Said air-heating furnace connects flat airslide disintegrating mill through feeding steam pipe, pulverizing steam pipe respectively.Connect hot precipitator on the said flat airslide disintegrating mill, finished product bin behind the connection powder on the hot precipitator.Feed bin connects flat airslide disintegrating mill through material handling spiral before the said powder.
Compared with present technology the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Utilize the unnecessary energy in power plant to replace the middle pressure superheated steam of boiler for producing, saved the energy, reduced production cost; Reduce the discharging of sulfur dioxide gas, reduced environmental pollution.
Description of drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals: finished product bin, 5-hot precipitator, the preceding feed bin of 6-powder, 7-material handling spiral, 8-feeding steam pipe, 9-pulverize steam pipe, 10-low-pressure superheated steam, 11-heat-exchanging chamber, the flat airslide disintegrating mill of 12-behind 1-neat gas burner, 2-air-heating furnace, 3-low-pressure saturated steam, the 4-powder.
The specific embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, the utility model comprises feed bin 6, material handling spiral 7, feeding steam pipe 8 before finished product bin 4 behind neat gas burner 1, air-heating furnace 2, the powder, hot precipitator 5, the powder, pulverizes steam pipe 9, heat-exchanging chamber 11 and flat airslide disintegrating mill 12.
Before the said air-heating furnace 2 neat gas burner 1 is installed, is provided with heat-exchanging chamber 11 in the air-heating furnace 2.Said air-heating furnace 2 connects flat airslide disintegrating mill 12 through feeding steam pipe 8, pulverizing steam pipe 9 respectively.Connect hot precipitator 5 on the said flat airslide disintegrating mill 12, finished product bin 4 behind the connection powder on the hot precipitator 5.Feed bin 6 connects flat airslide disintegrating mill 12 through material handling spiral 7 before the said powder.
When work, about 175 ℃ low-pressure saturated steams 3 through neat gas burner 1 and air-heating furnace 2 and heat-exchanging chamber 11, are heated to the low-pressure superheated steam 10 about 280 ~ 300 ℃.Open feeding steam pipe 8 then and carry out preheating with pulverizing 9 pairs of flat airslide disintegrating mills 12 of steam pipe and hot precipitator 5; After accomplishing, preheating opens material handling spiral 7; Titanium white powder is transported to vapour powder machine inlet capable through material handling spiral 7 and is pulverized by the pulverizing chamber that injection sprays into flat airslide disintegrating mill 12; The superheated steam high speed from nozzle spray people pulverizing chamber, forms a tangent line circle air-flow of rotation at a high speed with tangent line in pulverizing chamber, between this tangent line circle and pulverizing chamber cylindrical, also have many little eddy flows; Make fluid be the height vorticity, material brute force in high velocity air is collided and is pulverized.
When the titanium white powder particle reached a certain size, material is taken out of to the air-flow of central motion pulverized the district, gets into hot precipitator 5.Steam is discharged through air-introduced machine, and the titanium white powder after the pulverizing gets into finished product bin.Adjust the speed of material handling spiral 7 according to the particle diameter of titanium white powder finished product, thus the pulverizing quality of regulating finished product through the adjustment inlet amount.
Add hot-air with natural gas and again low-pressure saturated steam is heated into 280~300 ℃ of left and right sides superheated steams, improve vapor (steam) temperature gas flow rate is accelerated, help improving crushing effect; Improving vapor (steam) temperature simultaneously helps ensureing and the normal use of hot precipitator does not influence end product quality.
