Abstract
The invention discloses a protecting device of a dissolving tank inner wall of a alkali recovery furnace, comprising a alkali recovery furnace dissolving tank (1), and the alkali recovery furnace dissolving tank (1) is provided with a liquid protecting device (2) which can lead the liquid to flow along the dissolving tank inner wall. Through arranging the liquid protecting device at the alkali recovery furnace dissolving tank, the liquid protecting device can lead the whole dissolving tank inner wall to form a liquid protecting curtain from top to bottom; when the chute silencing or liquid melt dissolution and explosion occurs, and partial liquid melt flies toward the inner wall, the liquid melt is firstly contacted with the liquid protecting curtain of the inner wall, thereby avoiding that the high-temperature liquid melt is directly contacted with the dissolving tank inner wall, and the corrosion of the liquid melt to the dissolving tank inner wall of the alkali recovery furnace is effectively prevented; meanwhile, the liquid protecting curtain at the inner wall can wash away the liquid melt to the dissolving tank, and the long-term corrosion caused by bonding of the liquid melt at the dissolving tank inner wall is effectively avoided, and the continuous operation of the device and the safety factor of the device and the operator are increased.
Description
Technical field
The present invention relates to a kind of dissolving tank inner wall protector, particularly a kind of protector of dissolving tank inner wall of alkali recovery furnace.
Background technology
In industrial production; The main noise reduction mode of alkali recovery furnace chute melts all adopts steam, rare white liquid or water noise reduction mode; Because the pyritous melts is prone to produce blast in noise reduction and dissolution process; The pyritous melts all has very strong corrodibility in addition, causes dissolving tank inner wall of alkali recovery furnace (especially antetheca) when noise reduction, very easily to be melted the splash of thing institute, after the alkali recovery furnace long operational time; Dissolving tank inner wall will sustain damage because of the high temperature caustic corrosion of chute noise reduction or the splash of melts blast institute; Thereby cause lixator alkali lye to leak, higher threat equipment and operator's safety also can cause when serious whole alkali recovery furnace to stop when the alkali recovery furnace chute damages.
Summary of the invention
The technical problem that the present invention will solve is: a kind of possibility that reduces the dissolving tank inner wall damage is provided, effectively protects the protector of the dissolving tank inner wall of alkali recovery furnace of equipment and life safety, can overcome the deficiency of prior art.
Technical scheme of the present invention: it comprises the alkali recovery furnace lixator, and the alkali recovery furnace lixator is provided with and makes liquid along dissolving tank inner wall flowing fluid protector.
The liquid protector comprises shower and nozzle; Shower is arranged on the top of alkali recovery furnace lixator; The shape of its setting is identical with the shape of alkali recovery furnace lixator xsect, and the nozzle separation is connected on the shower, and the nozzle direction is towards the inwall of alkali recovery furnace lixator.
The nozzle configuration of nozzle is flat mouthful.
Nozzle evenly is connected on the shower.
The spray liquid of shower is water, diluent or noise reduction liquid.
Compare with prior art; The present invention's invention is through being provided with the liquid protector on the alkali recovery furnace lixator, the liquid protector can make whole dissolving tank inner wall on wall, form a liquid protection curtain from top to bottom, when chute noise reduction or melts dissolving blast; When the partial melting thing flies to inwall; At first contact, thereby avoided the pyritous melts directly to contact, prevented the corrosion of melts effectively dissolving tank inner wall of alkali recovery furnace with dissolving tank inner wall with the liquid protection curtain of inwall; The curtain of the protection of the liquid on inwall simultaneously also can dash melts to lixator, has effectively avoided melts to be bonded on the dissolving tank inner wall and the long-term corrosion that produces has improved the continuous maneuverability of equipment and equipment and operator's SF.The liquid protector comprises shower and nozzle, and shower is arranged on the top of alkali recovery furnace lixator, and shape is identical with the alkali recovery furnace lixator, and the nozzle separation is connected on the shower, and the nozzle direction is towards the inwall of alkali recovery furnace lixator.That this structure has is simple in structure, installation, meliority such as easy to maintenance.The nozzle configuration of nozzle is flat mouthful, and such nozzle can effectively make liquid form water curtain at dissolving tank inner wall of alkali recovery furnace; Nozzle evenly is connected on the shower, can guarantee the even of water curtain like this.
The present invention can also have on the corrosive chemical technique at other and uses, and has good value for applications.

Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment: as shown in Figure 1; Chute 5 effusive melts 6 are smashed by noise reduction steam 7; Become granular and distribute in alkali recovery furnace lixator 1, wherein the overwhelming majority directly falls on the lysate liquid level of alkali recovery furnace lixator 1, and few part flies to the inwall of alkali recovery furnace lixator 1.For preventing that melts from directly contacting with the inwall of alkali recovery furnace lixator 1; Be provided with one on the alkali recovery furnace lixator 1 now and can make liquid along dissolving tank inner wall flowing fluid protector 2, liquid protector 2 is made up of shower 3 and nozzle 4, and shower 3 is arranged on the top of alkali recovery furnace lixator 1; The shape of shape and alkali recovery furnace lixator 1 xsect identical (being mostly oval); The optional water of spray liquid, diluent or noise reduction liquid in the shower 3, nozzle 4 is evenly arranged on the shower 3 at interval, and the nozzle direction is towards the inwall of alkali recovery furnace lixator 1; Its fixed form, can select according to the size of alkali recovery furnace ability with the distance of dissolving tank inner wall; Nozzle 4 adopts flat mouthful of design, can guarantee that like this protection liquid that sprays is a covering of the fan, can form bigger liquid curtain 8; The quantity of shower nozzle decides according to the size of alkali recovery furnace lixator 1, and its principle is the inwall that the liquid curtain 8 of all shower nozzles sprinklings will cover whole alkali recovery furnace lixator 1.
Because chute 5 leans on the antetheca of alkali recovery furnace lixator 1; The antetheca of alkali recovery furnace lixator 1 is the place that needs most protection, therefore can take localised protection according to the fund and the condition of production; Compare with full inner wall protection; Localised protection is that the length minimizing of shower 3, the quantity of nozzle 4 reduce, 8 cover parts of the liquid curtain of formation, and the utilization principle of protector and basis do not change.
