Preferably, in one group of twin spray gun, the feed tube of each twin spray gun passes through one Round water pipe is connected with water supply line, and the air inlet pipe of each twin spray gun is connect by a round tracheae with steam line It is logical.
Preferably, the round water pipe and round tracheae are fixedly mounted on the securing means.
Preferably, the fixing device includes a circular frame, the circular frame includes an outer ring and some Bracing piece, flow distributor is arranged in the circle centre position of outer ring, is connected between outer ring and flow distributor by the bracing piece Connect and be fixed on cooling tower top plate.
Preferably, the flow distributor includes a ring-type housing and some distribution of air flow pieces, it is described some Distribution of air flow piece is evenly arranged in ring-type housing, and the inner circle centre position in ring-type housing of each distribution of air flow piece is connected as a single entity, Outer end is connected on the inwall of ring-type housing.
Preferably, the outer wall of the ring-type housing and the bracing piece of the fixing device are connected and fixed to cooling tower top On plate.
Preferably, the distribution of air flow piece is fanning strip.
Preferably, the Multipoint Uniform jet atomization device also include a data processing equipment and it is connected extremely Few two electric control valves, at least two temperature sensors, the electric control valve are separately mounted to water supply line and steam line On, the temperature sensor is arranged on the inlet and outlet of cooling tower.
The invention has the advantages that:The present invention is used for waste incineration and generating electricity gas cleaning cooling atomization spray of maximizing On water temperature reducing system, reasonably arrange that multiple atomized waters spray into point (general 3-6 point) at the top of cooling tower;It is same to use double fluid Body atomizing lance, the cooling water being atomized vertically is sprayed at the top of cooling tower, the atomization that the flue gas in cooling tower can be with penetrating Water is fully contacted, and its evaporating completely is reached to the effect of cooled flue gas temperature in a short time, it is to avoid the drop injection that atomization is fallen Dust stratification is caused on to tower wall;Meanwhile, the data that the present invention can also be gathered using temperature sensor are adjusted by data processing equipment The aperture of electric control valve, regulation hydraulic pressure and air pressure are saved, the penetrating speed of atomized water is controlled, so as to meet the maximization big load of equipment Requirement during many variations.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of the present invention.
Embodiment
With reference to Figure of description, the invention will be further described, but the invention is not limited in following examples.
As shown in figure 1, the Multipoint Uniform jet atomization device that the present invention is provided, including fixing device, flow distributor And one group of twin spray gun 5, fixing device is fixed at the top of cooling tower, and flow distributor is arranged in fixing device Portion's (air-flow enters inside cooling tower at the top of distributor through distributor), this group of twin spray gun, which is arranged on, to be fixed On device, and be evenly arranged around flow distributor, each twin spray gun with water supply line and steam line Connect (being omitted in figure).
The feed tube 5-1 of each twin spray gun is connect by a round water pipe 4 and interface 9 with water supply line Logical, the air inlet pipe 5-2 of each twin spray gun is connected by a round tracheae 3 and interface 8 with steam line.It is aobvious So, the round water pipe and round tracheae are fixedly mounted on the securing means.
The fixing device can use existing fixing device, or use following structure:Including a circular frame, The circular frame includes an outer ring 2 and some bracing pieces 1, and flow distributor is arranged in the circle centre position of outer ring, outer ring with It is connected and fixed between flow distributor by the bracing piece on cooling tower top plate.The diameter of outer ring and cooling tower it is interior Footpath is adapted, and outer ring is fixed on the inwall of cooling tower by bolt or other fixed components.
The flow distributor can use existing flow distributor, or use following structure:Including a ring Shape housing 7 and some distribution of air flow pieces 6, some distribution of air flow pieces are evenly arranged in ring-type housing, each distribution of air flow The inner circle centre position in ring-type housing of piece is connected as a single entity, and outer end is connected on the inwall of ring-type housing, the ring-type housing Outer wall and the bracing piece of the fixing device are connected and fixed on cooling tower top plate.Usually, the distribution of air flow piece is fan Shape piece.
The Multipoint Uniform jet atomization device also includes a data processing equipment (using industrial computer) and is connected thereto At least two electric control valves, at least two temperature sensors (being omitted in figure), the electric control valve is separately mounted to On water supply line and steam line, the temperature sensor is arranged on the inlet and outlet of cooling tower;Also, at the data Reason device can also be connected with the water pump of water supply line and the air pump of steam line, the rotating speed of control water pump and air pump.
The present invention is uniformly distributed in many twin spray gun at the top of cooling tower, passes through what cooling tower was imported and exported Temperature detection, many injection flow rates atomizing lance of Synchronization Control, such as 220 DEG C of cooling tower input gas temperature, outlet needs drop Temperature is to 160 DEG C, it is necessary to which total injection flow rate 4.5t/h, is divided into 3 to 6 points and sprays into cooling tower, and when being such as divided at 3, every sprays Rifle injection flow rate is 1.5t/h, and when being divided at 6, every is 0.75t/h spray gun injection flow rate.In the feelings of such injection flow rate Under condition, the pressure and hydraulic pressure of compressed air are reasonably controlled, the droplet particles being atomized out thinner (typically in below 80um) are easy to The short time evaporates in cooling tower, and rational layout points can also help flue gas to be mixed with the full and uniform of atomized drop, no Dust stratification is caused as the drop not being atomized in time is ejected into tower wall.Therefore, the Multipoint Uniform injection that the present invention is used Atomization structure can also meet requirement when changing the maximization big load of equipment more, so that controllable, homogenization is reached, it is synchronous high Effect.
