The utility model discloses the scheme of taking does: a be used for glass kiln SCR denitration soot blower, is parallel to each other including jetting pipe, nozzle, pipe fitting, pulse solenoid valve and gas holder, multiunit jetting pipe, the level is equally spaced fixes on the reactor, is located in the catalyst top, every jetting pipe below equidistance sets up a plurality of nozzles, the nozzle corresponds with catalyst hole position, jet manage be connected to the gas holder through pipe fitting and pulse solenoid valve on. This design simple structure, effect are obvious, and investment cost blows the ash than the sound wave will be reduced a lot, utilize electromagnetic pulse control valve control jetting cycle and circulation cycle, guarantee the jetting effect, take unique pattern of jetting mouth to mouth, and a set of orifice corresponds a catalyst promptly.

Description

One kind is used for glass furnace SCR denitration soot blower

Technical field

This utility model is applied to SCR denitration apparatus field, and more particularly, to a kind of glass furnace SCR denitration soot blowing that is used for fills Put.

Background technology

SCR (Selective Catalytic Reduction) is SCR technology, develops in recent years Comparatively fast, it is widely used in West Europe and Japan, current ammonia catalytic reduction process method is technology that should be with the most use.It does not have pair Product, does not form secondary pollution, and apparatus structure is simple, and removal efficiency height (up to more than 90%), reliable, is easy to tie up The advantages of shield.Selectivity refers in the effect of catalyst with oxygen existence condition, and NH3 is preferential and NOx occurs reduction removing Reaction, generates nitrogen and water, and the oxygen got along well in flue gas carries out oxidation reaction.

Catalyst plays very important effect in the entire system, but can produce substantial amounts of flying during denitration reaction Ash, and it is attached to the surface of catalyst, the catalytic effect of impact catalyst, also can produce a certain degree of damage to catalyst. For above-mentioned reasons, need catalyst is carried out soot blowing operation during SCR denitration, conventional soot-blowing mode has sonic soot blowing And steam soot blowing, but it is directed to 50m²Below during little glass furnace application, have the following disadvantages：Sonic soot blowing effect is poor, ash Dirt is difficult for drop-off, and steam soot blowing dynamics easily causes to catalyst greatly very much to wear and tear.

Utility model content

For the problems referred to above, this utility model provides one kind to be used for glass furnace SCR denitration soot blower, for solving 50m² Little glass furnace soot blower soot blowing effect is poor below, the problem of easy damaged catalyst.

For solving the above problems, scheme of the present utility model is：One kind is used for glass furnace SCR denitration soot blower, bag Include injection tube, nozzle, pipe fitting, impulse electromagnetic valve and air accumulator, multigroup injection tube is parallel to each other, and what level was equidistant is fixed on reaction On device, positioned at side on a catalyst, below each injection tube, it is placed equidistant multiple nozzles, nozzle and catalyst hole location pair Should, injection tube is connected on air accumulator by pipe fitting and impulse electromagnetic valve.

Preferably, described nozzle is connected with injection tube using easily detachable mode, leaves spray orifice after pulling down.

Preferably, described air accumulator is arranged on reactor by support meanss.

Advantage of the present utility model is：Structure is simple, and substantially, cost of investment will reduce a lot compared with sonic soot blowing effect, profit Control injection cycle and cycle period with electromagnetic pulse control valve it is ensured that injection effect, take and be blown pattern mouth to mouth, that is, one group Nozzle corresponds to one piece of catalyst, and because nozzle is quick detachable, soot blower can be realized being blown well format and form of nozzle injection simultaneously, Injection effect overcomes acoustic wave ash ejector vibration dust vibration not get off, and steam sootblower dynamics produces abrasion to catalyst greatly very much Result.

Brief description

Fig. 1 is soot blower structural representation；

In figure：1. reactor, 2. catalyst, 3. injection tube, 4. nozzle, 5. pipe fitting, 6. impulse electromagnetic valve, 7. air accumulator, 8. support meanss.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used for this utility model is described, but is not limited to scope of the present utility model.

As shown in figure 1, a kind of be used for glass furnace SCR denitration soot blower, it is arranged on reactor on SCR denitration reactor On 1, multigroup injection tube 3 is installed above catalyst 2, is parallel to each other between injection tube 3, level is equidistantly placed, under injection tube 3 Side is placed equidistant multiple nozzles 4, and gas sprays from nozzle 4 through injection tube 3, blows to catalyst 2, the position of nozzle 4 with urge In agent 2, the position of hole is corresponding, so that the gas spraying in nozzle 4 can be blowed in the hole of catalyst 2, injection tube 3 is passed through Pipe fitting 5 is connected with impulse electromagnetic valve 6 and air accumulator 7 successively.Nozzle 4 is arranged in injection tube 3 using easily detachable mode, pulls down Spray orifice is still left afterwards, gas still can be blowed to catalyst 2 by spray orifice in injection tube 3.Air accumulator 7 is placed on support meanss 8 On, support meanss 8 are arranged on outside reactor 1.

In order to solve currently in 50m²The exhaust gas components that following little glass furnace produces are more complicated, relative mass Relatively light, there is viscosity, be attached to catalyst surface, and this kiln dynamically changes fire frequently, dust yield occurs acute variation Problem, devise this utility model.This utility model can be effectively improved acoustic wave ash ejector vibration dust vibration and not get off, steam Soot blower dynamics produces greatly very much the result of abrasion to catalyst, and the smoke dust for solving glass furnace puerperal sticks to catalysis Catalyst poisoning, the problem of blocking is made above agent.
