Abstract
The invention discloses a sludge nozzle. The sludge nozzle comprises a feeding pipe, an increasing pipe and a blind plate seal head, wherein the necking end of the conical increasing pipe is connected with the feeding pipe, the arc-shaped blind plate seal head is arranged at the open end of the conical increasing pipe, the arc-shaped portion protrudes outside, and a set of spraying holes are formed in the blind plate seal head. The external diameter of the blind plate seal head is double of the pipe diameter of the feeding pipe, the total area of the spraying holes formed in the blind plate seal head is equal to the cross sectional area of the feeding pipe, and the spraying holes are evenly distributed in the blind plate seal head in a regular hexagon mode. The sludge nozzle cannot be blocked by sludge in the sludge drying process and can be connected to a sludge pump through flanges or threads, an additional pressure device is not needed, and the difficulty and the cost of the follow-up operation are greatly reduced.
Description
Technical field
The invention belongs to energy environment protection field, relate to a kind of novel sludge drier parts, is a kind of mud nozzle specifically.
Background technology
Along with the continuous expansion of municipal sewage treatment scale, sewage disposal degree raises year by year, and sludge yield also sharply increases.Mud contains toxic organic compound, pathogenic microorganisms and heavy metal, can produce serious harm to environment, as deals with improperly or not in time, can bring serious secondary pollution.Therefore, how effectively city sewage and sludge to be disposed, become the very important problem that is related to urban society and sustainable economic development.
Sewage sludge is the very high floccule of a kind of moisture content that sewage treatment plant produces in sewage purification process, it is actually the extremely complicated heterogeneous body that organic relic, bacterium thalline, inorganic particle, colloid in sewage form, it is a kind of dope between liquid and solid, particle is thinner, proportion is less, high and the difficult dehydration of moisture content, belongs to the hydrophilic substance of colloid form structure.
Drying sludge is exactly to utilize heat energy by a kind for the treatment of process of the moisture rapid evaporation in mud.Mud is after traditional concentrated and dewatering process is processed, and moisture content can not reach below 60%, and through mechanical dehydration, moisture percentage in sewage sludge is 75% left and right.Reach the further dehydration to mud, both economical method is to adopt dry technology.Drying sludge is the preorder technique of various sludge disposal technologies, by drying sludge, reduces the volume before sludge ultimate disposal, reaches the object of sludge reduction, to reduce the expense of Treatment of Sludge and final disposal.
Existing sludge drier can be divided into two classes: direct drying equipment and contact drying equipment.Convection drying claims again convective drying.In operating process, thermal medium (hot-air, combustion gas or steam etc.) directly contacts with mud, absorbs the moisture in mud, and the dewatered sludge after processing need carry out separated with thermal medium.Tail gas discharges after innoxious.This technomania efficiency of transmission and evaporation rate are higher, can make the solid content of mud from 25% raising 85%～95%.Contact drying equipment by heat exchanger, is passed to thermal medium (conduction oil, steam or air) by the heat of high-temperature flue gas, and medium circulates in the loop of a sealing, does not contact with the mud being dried.
But no matter be direct drying equipment or contact drying equipment, at sludge pump, in drying equipment fill process, tend to the phenomenon that occurs that cloth is inhomogeneous.In order to address this problem, often on the feed arrangement of sludge drier, nozzle is installed.On market, existing mud nozzle great majority are atomizer and spiral nozzle: atomizer utilize compressed air and liquid friction, produce all even fine and closely woven atomizing effects, but it is that 85% following sludge drying mechanism can stop up that this kind of nozzle applies to processing moisture content, and atomizer resistance is large, energy consumption is high; Spiral nozzle has internal and external screw thread type, be a kind of solid-cone or nozzle, straight-through type flow passage design, can make liquid reach maximum stream flow at the pipeline of intended size, can make liquid or slip, after tangent or collision, become small liquid pearl ejection and form vaporific by the helicoid that diminishes continuously.According to the industrial design parameter of spiral nozzle, in order to make mud discharging state, be spray pattern, if adopt the pipeline of 2in reinforced, minimum reinforced flow is 550L/min, energy consumption is high.In mud, salt content is higher, the corrosion that can produce equipment tool; In mud, contain a large amount of fine particles, be that in nozzle friction or collision process, nozzle wear is larger.
Summary of the invention
For in above sludge dry system, mud spray nozzle clogging and resistance are large, energy consumption is high; Sludge quality is sticky, easily reunion, tend to the problems such as phenomenon that occur that cloth is inhomogeneous, the object of this invention is to provide a kind of mud nozzle, in drying sludge process, can there is not sludge blockage in this nozzle, can or be threaded onto sludge pump by flange, do not need extra pressue device, greatly reduce difficulty and the cost of subsequent operation.
The object of the invention is to be achieved through the following technical solutions:
A kind of mud nozzle, it is characterized in that: this nozzle comprises feed pipe, increaser and blind plate end socket, and the necking end of conical diffuser is connected with feed pipe, arc blind plate end socket is arranged on the openend of conical diffuser, and arc protrudes laterally, on blind plate end socket, be provided with one group of spray orifice.
In the present invention, the external diameter of described blind plate end socket is 2 times of feed pipe calibers.On blind plate end socket, the gross area of one group of spray orifice is identical with feed pipe cross-sectional area.One group of spray orifice is evenly distributed on arc blind plate end socket, adopts regular hexagon to distribute.
The present invention is similar to shower nozzle, in the lower end of device, is an increaser, and end adopts stainless steel blind plate solder up, and while showing that according to experimental result the diameter of blind plate equals two times of material feeding pipe diameters, the energy loss of system is minimum.
In order to reduce energy loss, according to feeding device line size in sludge drier and mud situation, determine perforate number, the bore size of nozzle.In shower nozzle, the gross area of aperture approaches or equals feeder feed pipe cross-sectional area, can reach the requirement of uniform distribution, can reduce resistance again.
The invention has the beneficial effects as follows: processing cost is low, technique is simple, and in sewage sludge feed process, the resistance of ducting of generation is little, and energy loss is low, wear-resisting, corrosion-resistant, does not forever stop up, and does not need extra pressue device.

The specific embodiment
A nozzle, is shown in Fig. 1 and Fig. 2, and this nozzle comprises feed pipe 1, increaser 2 and blind plate end socket 3, the necking end of conical diffuser is connected with feed pipe, arc blind plate end socket is arranged on the openend of conical diffuser, and arc protrudes laterally, is provided with one group of spray orifice 4 on blind plate end socket.The external diameter of blind plate end socket is 2 times of feed pipe calibers.On blind plate end socket, the gross area of one group of spray orifice is identical with feed pipe cross-sectional area.One group of spray orifice is evenly distributed on arc blind plate end socket.
The present invention is similar to shower nozzle, in the lower end of device, is an increaser, and end adopts stainless steel blind plate solder up.According to the treating capacity of sludge drying mechanism, determine sewage sludge feed pipe caliber.While selecting blind plate end socket, its diameter is 2 times of feed pipes.According to the perforate on blind plate end socket of feed pipe area, basic principle is that the gross area of aperture approaches or equals feeder feed pipe cross-sectional area.Even for cloth, perforate is to adopt regular hexagon to distribute.
