Description
Technical field
The present invention relates to the devices of gas cleaning machinery technical field, specially protection cooling spray gun.
Background technology
In entire flue gas purification system, reaction tower is a vital ring, 200 DEG C of boiler generation to burn away the refuse
Harmful high-temperature flue gas is directly entered reaction tower and is handled above.And when using dry-process deacidification, cooling spray gun is control reaction tower
The key factor of outlet temperature：Flue gas exit temperature is excessively high, can damage the dust-collecting bag being connected therewith with reaction tower, conversely,
Outlet temperature is too low, and flue gas easily condenses in dust-collecting bag again, and then influences deduster normal work, therefore the spray gun that cools down continues
Entire flue gas purification system is effectively worked to occupy an important position.
The cooling spray gun 1 used in the prior art is to be fixedly mounted in the casing 2 on reaction tower 3, as shown in Figure 1, nothing
Method is stretched, therefore the nozzle of spray gun is in contact for a long time with the corrosive gas inside reaction tower, is easily etched, greatly shortens
The service life of cooling spray gun.
Invention content
The nozzle of middle the spray gun easily gas pickling of being corroded property, the shortcomings that shortening the working life for the above-mentioned prior art, this
Invention provide protection cooling spray gun device, can make to stretch during cooling spray gun use, shrink when not in use, and be truncated valve every
The connection with reaction tower is opened, spray gun is avoided and is in direct contact and the gas pickling of being corroded property with the gas in reaction tower for a long time,
Effectively extend the service life of cooling spray gun.
The present invention adopts the following technical scheme that：The device of protection cooling spray gun, including the spray gun that cools down, the cooling spray gun
Reaction tower is installed on by casing, which is characterized in that further include automatic extending-contracting apparatus and block valve, the automatic extending-contracting apparatus packet
Cylinder, the piston rod connection push plate of the cylinder are included, the jet pipe of the cooling spray gun is set in the push plate, and described sleeve pipe is close
Port is blocked in reaction tower one end, the block valve pass through the jet pipe for blocking port and the cooling spray gun intersect realize block,
It connects.
It is further characterized by：
The block valve includes valve rod and valve pocket；
The block valve is pneumatic block valve or electronic block valve.
In the above structure of the present invention, the setting of automatic extending-contracting apparatus and block valve makes the cooling being mounted in casing spray
Rifle becomes telescopic action formula, and due to the barrier of block valve, effectively prevent cooling spray gun for a long time, uninterruptedly from fixed
Contact with corrosive gas, so as to substantially prolong the service life of cooling spray gun.
Description of the drawings
Fig. 1 is the structure diagram of the prior art.
Fig. 2 is the structure diagram of the present invention.
Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings：
As shown in Fig. 2, the present invention provides the device of protection cooling spray gun, including the spray gun 1 that cools down, cooling spray gun 1 is pacified by casing 2
Loaded on reaction tower 3, automatic extending-contracting apparatus and block valve are further included, automatic extending-contracting apparatus includes cylinder 4, the piston rod of cylinder 4
Push plate 8 is connected, the jet pipe of cooling spray gun 1 is set in push plate 8, and casing 2 blocks port 5, block valve close to one end of reaction tower 3
It realizes across blocking port 5 with the jet pipe for the spray gun 1 that cools down and intersecting and blocks, connects, block valve is pneumatic block valve or electronic section
Disconnected valve, including valve rod 7 and valve pocket 6.
When needing using cooling spray gun, it is pneumatic that automatic extending-contracting apparatus, opening are started by the electrical system of integrated control
Or electronic block valve, it passes downwardly through under the thrust that is generated in cylinder moving of cooling spray gun and blocks port up to stretching into reaction tower
It is interior, cool down to the high-temperature flue gas in production process；When do not need in use, automatic extending-contracting apparatus operation generate thrust will drop
Warm spray gun pushes up, and cooling spray gun is contracted to pneumatic block valve when blocking above port and closes, so as to avoid cooling spray gun with
Corrosive gas is in direct contact in reaction tower, the service life of cooling spray gun is substantially prolonged, in particular it is preferred to use gate valve
Formula block valve is blocked and is connected to be better achieved.
