Be described further below with reference to the technique effect of accompanying drawing to design of the present invention, concrete structure and generation, to understand object of the present invention, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is that the present invention is with the structural representation of specific embodiment.
Reference numeral: warehouse of sludge 1, dispenser 2, jet pump 3, first blower fan 4, incinerator 5, gas-solid separator 6, second blower fan 7, powder grain material tank truck 8, straight-through branch road 9, powder grain material path 10.
Detailed description of the invention
As shown in Figure 1, a specific embodiment of the present invention, a kind of induction system of powder mud, comprises a warehouse of sludge 1.Warehouse of sludge 1 is cylindrical shape, and Lower Half is turbination.The charging aperture of warehouse of sludge 1 is through with the powder grain material tank truck 8 carrying air-pressure equipment.Carry the powder grain material tank truck 8 of air-pressure equipment, mud can be sent into warehouse of sludge 1 from charging aperture and carry out discharging by the air of the certain pressure that its air-pressure equipment produces, and the large quantity of air that air-pressure equipment is brought into and the airborne dust thereupon produced and foul smell can enter warehouse of sludge 1 with mud simultaneously.
Warehouse of sludge 1 has charging aperture at the first half, has discharging opening in Lower Half.
The discharging opening of warehouse of sludge 1 is provided with dispenser 2.The exit of dispenser 2 is provided with jet pump 3.Dispenser 2 regulates the sludge quantity entering into jet pump 3 in warehouse of sludge 1 by valve body.
The air inlet of jet pump 3 is provided with the first blower fan 4.First blower fan 4 forms negative pressure by jet pump 3 in dispenser 2 bottom.Under the effect of negative pressure, the powder mud in warehouse of sludge 1 is transported to incinerator 5 by pipeline, realizes utilizing gas as the technical purpose of transmitting power.
Meanwhile, gas passage is formed with between the upside of warehouse of sludge 1 and incinerator 5.This gas passage is also provided with gas-solid separator 6 and the second blower fan 7.
Straight-through branch road 9 is also provided with between the upside of warehouse of sludge 1 and incinerator 5.When discharging, can close the first blower fan 4, air air-pressure equipment being brought into warehouse of sludge 1 directly sends into incinerator 5; The diffusion of further minimizing foul smell.
In some embodiments, the upside of warehouse of sludge 1 also can arrange pipeline, is led directly to by powder grain material path 10 and incinerator 5.
Second blower fan 7 is normally open, to form negative pressure on warehouse of sludge 1 top.Foul smell in warehouse of sludge 1 is also transported to incinerator 5 under this suction function.
In some are specifically implemented, gas-solid separator 6 can be cyclone separator, sack cleaner or screen pack, to realize the solid particle in the foul smell with little solid particle to be separated, foul smell is delivered to incinerator 5.
System of the present invention, time in working order, warehouse of sludge 1 keeps negative pressure always.
Powder sludge conveying system of the present invention, be particularly useful for moisture content lower than 40% the conveying of powder mud.Because moisture percentage in sewage sludge is too low, just there is no mobility completely, cannot pneumatic transportation be utilized.Moisture percentage in sewage sludge is too high, then proportion is too large, and pneumatic transportation is not.
Processing method one specific embodiment of induction system of the present invention, as follows:
First, mud is discharged into warehouse of sludge 1 from charging aperture by powder grain material tank truck 8.During discharging, in warehouse of sludge 1, airborne dust and foul smell can be produced.
Therefore, during discharging, close the first blower fan 4, by being provided with straight-through branch road 9 between the upside of warehouse of sludge 1 and incinerator 5, air air-pressure equipment being brought into warehouse of sludge 1 directly sends into incinerator 5; Second blower fan 7 keeps normally open;
After discharging completes, open dispenser 2 and the first blower fan 4 simultaneously.
Then, powder mud in warehouse of sludge 1 regulates the feeding coal entering jet pump 3 by bottom dispenser 2, first blower fan 4 forms negative pressure in dispenser 2 bottom after jet pump 3, mud sucks and brings conveyance conduit under the kinetic energy of the gas produced at the first blower fan 4 by this negative pressure, and mud delivers into incinerator 5 and burns the most at last.
Native system is when discharging or not discharging, the second blower fan 7 is all kept to open, by the second blower fan 7, the foul smell suction incinerator 5 in warehouse of sludge 1 is burned, and keeping tiny structure in warehouse of sludge 1 to fall apart to prevent foul smell outward, solid particle (airborne dust) separating cycle in foul smell can be got back to warehouse of sludge 1 by gas-solid separator 6.
Obviously, discharging is to carry out to warehouse of sludge 1 and conveying mud to the process of incinerator 5 simultaneously.
Said structure of the present invention, adopts the jet pump be connected with the first blower fan to form local decompression in the bottom of warehouse of sludge, makes powder mud enter conveyance conduit smoothly under wind-force effect, thus be transported to incinerator.Meanwhile, the second blower fan be connected with warehouse of sludge effectively keeps the tiny structure on warehouse of sludge top, and the airborne dust that produces in discharge process and foul smell can not be dispersed in surrounding environment.
The present invention has departed from traditional mechanical type mode of movement completely, the power that the air-flow utilizing blower fan to produce is carried as mud.Adopt induction system of the present invention to carry powder mud, can avoid the foul smell in course of conveying and flue dust excessive, noise is low, carries easy to control, simple to operate easy to maintenance, greatly reduces and adopts area shared by other plant equipment and cost.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
