Description

Heterogeneous water smoke is pounced on the dirt deduster

Technical field

The utility model relates to a kind of dusty gas cleaner.

Background technology

At present, iron making and sintering factory is on the feed proportioning pipeline under China iron and steel system, need with quick lime and water in proportion mixture slaking enter the batch mixing chamber later on, quick lime with chemical reaction tempestuously takes place after water mixes, the water vapour that its high temperature produces is taken away a large amount of lime dusts, fly upward everywhere, very big to production scene and surrounding enviroment influence.Original dedusting method has two kinds: a kind of is to utilize the airduct of sintering machine system electric cleaner through this sky, position, opening an arm takes out the dirt mouth with the bottom and docks, because the dusty gas stickiness is very strong, generally less than one month with line clogging, harm host computer system ordinary production when serious.Two kinds is a supporting foam type deduster, and this mode has two defectives: 1. need to build cesspool and accept the sewage that deduster is discharged, it is big that the time has been grown desilting mud workload, causes secondary environmental pollution simultaneously; 2. this deduster is every 10-15 days needs labor cleaning pipelines and screen pack, maintenance cost very high and because poor hygienic, the bad construction of reason such as hot and humid.Often after stopping up, cause equipment failure.

The utility model content

The purpose of this utility model is to provide a kind of and can normally moves for a long time, solves the cleaner of the dusty gas of band stickiness.

The purpose of this utility model is achieved through the following channels: heterogeneous water smoke is pounced on the dirt deduster, it comprises the support of casing and supporting box, the rip cutting of deduster casing is divided into two operating rooms, be separation chamber and spray chamber, the bottom, operating room is a water tank, separation chamber and spray chamber the first half are isolated by dividing plate, and the S passage that the latter half is imbedded in the water tank by part connects; The spray chamber inner tip is equipped with the high-pressure water mist nozzle, has the spray chamber air inlet on the sidewall of spray chamber below the hydraulic spray nozzle; The casing top is equipped with centrifugal fan, and the exhaust outlet of blower fan is connected with the fan air inlet at top, separation chamber; Water tank bottom links to each other with dredge pump.On separation chamber's madial wall water fender is installed.The S passage is equipped with the hydraulic spray nozzle of water conservancy diversion by spray chamber one side-entrance place.Water level induction control warning device is installed in the water tank of deduster, and this device is made up of stainless steel floating ball, glass tube, inductance approach switch and control warning circuit; Its bottom of glass tube that stainless steel floating ball is equipped with in inside with is communicated with water tank, the water tank water level inside changes by the stainless steel floating ball startup and feeds back signal to the control warning circuit near switch, controls warning circuit and closes or open water inlet automatically, the sound simultaneously gives the alarm.

The heterogeneous water smoke of the utility model is pounced on the dirt deduster and is compared with existing same category of device, and its advantage is: 1. uptime significant prolongation, and the efficiency of dust collection height can qualified discharge; 2. realize multifunctional electromechanical integrated, the automaticity height; 3. energy-saving and cost-reducing, utilize the sewage assimilation of quicklime using, non-secondary pollution.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the utility model structural representation;

Fig. 2 is water level induction control warning device structural representation.

The specific embodiment

As shown in Figure 1, the heterogeneous water smoke of the utility model is pounced on the dirt deduster, it comprises the support 10 of casing 9 and supporting

box

9,9 rip cuttings of deduster casing are divided into two operating rooms, be separation chamber 5 and spray chamber 2, the bottom, operating room is a water tank 3, and separation chamber 5 is isolated by dividing plate 11 with spray chamber 2 the first half, and the S passage 4 that the latter half is imbedded in the water tank 3 by part connects; Spray chamber 2 inner tip are equipped with high-pressure water mist nozzle 7, have spray chamber air inlet 1 on the sidewall of spray chamber 2 below the hydraulic spray nozzle 7, and S passage 4 is equipped with the hydraulic spray nozzle 14 of water conservancy diversion by spray chamber 2 one side-entrances place; Casing 9 tops are equipped with centrifugal fan 12, and the exhaust outlet 6 of blower fan 12 is connected with the fan air inlet 20 at 5 tops, separation chamber, on separation chamber's 5 madial walls water fender 8 is installed; Water tank 3 bottoms link to each other with dredge pump 19.Seabed osculum 13 is positioned at the bottom of water tank 3, the surplus water of emptying when being used for Long-time Shut-down or maintenance.

As shown in Figure 2, water level induction control warning device is installed in the water tank 3 of deduster, this device is made up of stainless steel floating ball 15, glass tube 16, inductance approach switch 17 and control warning circuit 18; Its bottom of glass tube 16 that stainless steel floating ball 15 is equipped with in inside be communicated with water tank 3, water tank 3 water level inside change by stainless steel floating ball 15 demonstrations, stainless steel floating ball 15 just starting switch near near switch 17 time, be provided with three near switch 17, be respectively upper limit water level, normal water level and lower limit water level, give control warning circuit 18 near switch 17 with signal feedback, water inlet is closed or opened to control warning circuit 18 automatically, and the sound simultaneously gives the alarm.For example descend when pressure of supply water, cause that water level descends, stainless steel floating ball 15 drop to the lower limit water level near switch 17, control warning circuit 18 starts water replanishing devices automatically, the sound simultaneously gives the alarm.

The course of work of this device is as follows: dusty gas imports deduster by spray chamber air inlet 1, high-pressure water mist nozzle 7 is to gas atomization, because finding time of centrifugal fan 12, the water surface at the effect downstream acceleration shock water tank 3 of negative pressure produces spray and water smoke, coarse dust directly enters in the water and is absorbed by water, and dusty gas and spray water smoke are forced through S shape passage 4, makes dirt gas and water generates self-excitation absorption, improve the gas-vapor mix effect, thereby reach good dust removing effects.Purified gas bump water fender dehydration back is discharged by deduster exhaust outlet 6, and the gas of discharge reaches discharging standards.
