Abstract
The utility model provides a kind of fire-fighting spray device of protecting chimney internal cylinder, comprise a fire-fighting spraying water pump, by a pipeline group, be communicated with a technique water tank and some fire-fighting spraying ozzles, described pipeline group comprises main pipeline, be arranged at the valve group on main pipeline and be communicated in some laterals of main pipeline end; Described lateral is positioned at an absorption tower and exports clean flue, and described fire-fighting spraying ozzle is arranged on lateral respectively.On absorption tower, export clean flue and on the position near absorption tower and convenient operation, fire-fighting spray device is set as far as possible, can be the in the situation that of absorption tower superhigh temperature or unexpected fire, fast reaction starts spray equipment automatically, by fire-fighting spray device, form water curtain, play the object of isolating with fiber glass reinforced plastic chimney, can avoid the maximum destruction of naked light to chimney internal cylinder as far as possible.
Description
Technical field
The utility model belongs to flue gas desulfurization technique field, relates to a kind of fire-fighting spray device of protecting chimney internal cylinder.
Background technology
Due to fiber glass reinforced plastic chimney have corrosion-resistant, the advantage such as designability is strong, and investment is supported, short construction period, at present very extensive in the application of coal-burning power plant.Because desulphurization system is that whole power-plant flue gas enters chimney end equipment before, so the security reliability of desulfurizer has directly affected the security reliability of chimney and even whole power plant.In at present a lot of desulfurization project, can accident spray system be set at absorption tower gas approach.If but absorption tower this in accident conditions such as cutting or the operation such as welding cause occurring catching fire, the fiber glass reinforced plastic chimney inner core that probably ignites, produces potential safety hazard.
Utility model content
For the problems referred to above, the utility model provides a kind of fire-fighting spray device, in order to protection, absorbs the fiber glass reinforced plastic chimney inner core after the clean flue of outlet, and manufacturing process is simple, easy to maintenance.
The purpose of this utility model is to provide a kind of fire-fighting spray device of protecting chimney internal cylinder, comprise a fire-fighting spraying water pump, by a pipeline group, be communicated with a technique water tank and some fire-fighting spraying ozzles, described pipeline group comprises main pipeline, be arranged at the valve group on main pipeline and be communicated in some laterals of main pipeline end; Described lateral is positioned at an absorption tower and exports clean flue, and described fire-fighting spraying ozzle is arranged on lateral respectively.
Further, also comprise a standby feeding spraying pump in parallel with fire-fighting spraying water pump.
Further, described valve group comprises the motor regulated valve of quick startup and manually overhauls valve.
Further, the material of described main pipeline is carbon steel.
Further, the material of described lateral is stainless steel.
Further, the arrangement of described spray ozzle is uniform.
Fire-fighting spray device of the present utility model is arranged on the clean flue between absorption tower outlet and chimney entrance, independently fire-fighting spraying water pump is set, special control valve group.Feeding spraying pump power supply connects emergency power supply, is provided with standbyly simultaneously, fully guarantees that water source is reliable and stable; Control valve group is provided with bypass, is convenient to real-time examination and repair and safeguards electrically operated valve; Be arranged in the clean flue behind absorption tower, can avoid absorption tower itself to occur the destruction that accident is brought to chimney.
At present, many coal-burning power plants adopt fiber glass reinforced plastic chimney inner core, and this just has higher requirement to the security of desulfurizer.Absorption tower exports clean flue and on the position near absorption tower and convenient operation, fire-fighting spray device is set as far as possible, can be the in the situation that of absorption tower superhigh temperature or unexpected fire, fast reaction starts spray equipment automatically, by fire-fighting spray device, form water curtain, play the object of isolating with fiber glass reinforced plastic chimney, can avoid the maximum destruction of naked light to chimney internal cylinder as far as possible.And utilize the intrinsic pond of desulfurizer as technique water tank, i.e. water source.At absorption tower gas approach, accident spray system is set with prior art and compares, the utlity model has the features such as device is simple, reliability is high, maintenance management is easy, there is high application value.
Accompanying drawing explanation
Fig. 1 is the structural representation of fire-fighting spray device in the utility model embodiment.
Symbol description in figure:
1-technique water tank; 2-fire-fighting spraying water pump; 2 ＇-standby feeding spraying pump; 3-carbon steel piping; 4-valve group; 5-absorption tower exports clean flue; 6-stainless steel pipes; 7-fire-fighting spraying ozzle.
The specific embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate institute's accompanying drawing to be described in detail below.
Embodiment:
As shown in Figure 1, the fire-fighting spray device that the utility model provides, can protect the fiber glass reinforced plastic chimney inner core of desulphurization system end.Its concrete structure that forms is: comprise technique water tank 1, fire-fighting spraying water pump 2 and standby feeding spraying pump 2 ＇ from 1 water intaking of technique water tank, fire-fighting spraying water pump 2 walks abreast and is communicated to the carbon steel piping 3 as main pipeline with standby feeding spraying pump 2 ＇, carbon steel piping 3 is provided with valve group 4, valve group 4 is controlled the switching of main pipeline, the manually-operated gate using when comprising the electrically operated valve using while regulating and overhauling.The end of carbon steel piping 3 is communicated with the many stainless steel pipes 6 as lateral, and stainless steel pipes 6 gos deep into absorption tower and exports in clean flue 5, and its quantity depends primarily on the bore that absorption tower exports clean flue 5.3-5 the fire-fighting spraying ozzle 7 of having an appointment is set on every stainless steel pipes 6 separately.In the situation that having an accident, fire-fighting spray device electrically operated valve starts, and the water in water source established technology water tank 1, by the adjusting of fire-fighting spraying water pump 1, main pipeline and valve group 4, from 7 ejections of fire-fighting spraying ozzle, forms rapidly water curtain, and the water yield is greatly about 150m
3/ h, prevents fire involving glass chimney internal cylinder.The in the situation that of preventing from occurring fire suddenly on absorption tower, by absorption tower, export 5 pairs of fiber glass reinforced plastic chimney inner cores of clean flue and produce destroying infection.
The present embodiment is set up independently fire-fighting spraying water pump, special control valve group, and stainless pipeline and spray spout, reliability is high, and processing technology is simple, very easily promotes and realizes.
