Abstract
A novel ammonia and air mixer comprises a mixing drum, one end of the mixing drum is an air inlet, and the other end of the mixing drum is a mixed gas outlet. The novel ammonia and air mixer is characterized in that a cross-shaped framework is arranged in the mixing drum, the interior of the framework is of a hollow structure, four triangular prisms are arranged on the framework, the triangular prisms are all right-angled triangular prisms, the triangular prisms are all located in the middles of corresponding framework bodies, the bottoms of the triangular prisms are communicated with the cross-shaped framework, multiple ammonia spraying holes are formed in the bevels, close to the air inlet direction, of the triangular prisms, the front end, close to the air inlet direction, of each ammonia spraying hole is made into a protruding structure, and a tail wing is arranged at the tail end of the same face of each triangular prism in the air outlet direction. The novel ammonia and air mixer is suitable for gas with different flows, the resistance to the mixed gas is smaller, the loss of the gas flow rate is less, and the gas mixing effect is good.
Description
Technical field
The present invention relates to gas denitrifying technology field, be specifically related to a kind of novel ammonia air mixer for selective catalytic reduction.
Background technology
General ammonia air mixer adopts baffle-type blender and cyclone type blender, meet stop collision after ammonia mixes with air rebound or form swirling eddy through cyclone type deflector, thus ammonia and air are mixed to a certain extent, mixed effect is limited and baffle plate is larger to air drag, when air mass flow increases, effect is poor, reduce mixed gas outlet flow velocity, affect the spray ammonia effect of the ammonia-spraying grid of next stage.
Summary of the invention
The object of the invention is to, provide a kind of ammonia and air good mixing effect, and mixed airflow prompt drop is low less, be applicable to the novel ammonia air mixer of various flow.
Technical scheme of the present invention is: a kind of novel ammonia air mixer, comprise mixing drum, mixing drum one end is air intake, the other end is mixed gas outlet, it is characterized in that: in described mixing drum, cruciform skeleton is set, skeletal internal is hollow structure, skeleton arranges four triangular prisms, triangular prism is right-angle prismatic post, each root triangular prism is all positioned at the middle part of respective skeleton, communicate with cruciform skeleton bottom triangular prism, on the inclined-plane of airintake direction, some spray ammonia holes are arranged at triangular prism, each spray ammonia hole is made into convex type structure near the front end of airintake direction, the end flowing out direction at the same face air-flow arranges empennage.

Detailed description of the invention
Specific embodiment of the invention scheme is a kind of novel ammonia air mixer, comprise mixing drum 1, mixing drum one end is air intake, the other end is mixed gas outlet, it is characterized in that: cruciform skeleton 6 is set in described mixing drum, skeleton 6 inside is hollow structure, ammonia enters triangular prism inside 12 by skeleton, skeleton arranges four triangular prisms 2/3/4/5, triangular prism is right-angle prismatic post, each root triangular prism is all positioned at the middle part of respective skeleton, communicate with cruciform skeleton bottom triangular prism, on the inclined-plane of airintake direction 7, some spray ammonia holes 10 are arranged at triangular prism, each spray ammonia hole is made into convex type structure 9 near the front end of airintake direction, the end flowing out direction at the same face air-flow arranges empennage 11.
The present invention arranges cruciform skeleton in internal mixer, skeleton arranges four right-angle prismatic posts, ammonia enters triangular prism inner plenum 12 from skeleton, mixed with air on touch panel 8 by spray ammonia hole 10, the projection 9 of spray front portion, ammonia hole 10 can reduce resistance when air sprays ammonia, and ammonia is mixed more fully with air.Partial air can be changed the flow direction by triangular prism and empennage thereof, and can also lengthen empennage 11 when flow increases, to reach the effect of disturbance gaseous mixture, in triangular prism, two acute angles suitably can regulate according to gas flow, promote the mixed effect of gas further.Compared with common ammonia air mixer, mixed effect of the present invention is better, and effect is remarkable equally when flow increases, simultaneously less for air resistance in mixing drum, and gas flow rate loss is few.
Claims (1)
