Abstract
Provided is a double-fluid atomizing spray gun. The double-fluid atomizing spray gun comprises a liquid flow pipeline, an air flow pipeline, a throat pipe, a spray head, a block and spray holes. The liquid flow pipeline is arranged in the air flow pipeline which is coaxially arranged with the liquid flow pipeline. The throat pipe is arranged at the tail end of the air flow pipeline. The spray head is in threaded connection with the outside of the throat pipe. The block is fixed at the bottom of the spray head. The spray holes, arranged at the bottom of the spray head, are located around the block. The double-fluid atomizing spray gun has following beneficial effects: an atomizing principle by combination of secondary fragmentation, air mixing and air-flow friction is adopted; when a nozzle normally operates, compressed air and solution with certain pressure are given to the spray gun at the same time; tiny particles are generated by striking and mixing operation between compressed air and solution for numerous times in the interior of the spray gun; compared with a single-fluid spray gun, the double-fluid spray gun is capable of not only reducing pressure of solution but producing the tiny atomizing particles when guiding compressed air; and the atomized particles are 80 microns in average diameter so that the total superficial area of liquid drops is increased by multiple times.
Description
Technical field
The utility model relates to denitration technology, relates in particular to a kind of twin spray gun.
Background technology
In recent years, remove the process of nitrogen oxide in combustion product gases, antipollution importance, has been carried out shrilly as worldwide problem, domesticly carries out cement denitration, still belongs to and explores demonstration phase, does not also carry out Scientific summarization.Whether various design technology technology paths and equipment facility scientific and reasonable, reliable? denitration efficiency, operating cost, cement energy consumption, secondary pollution discharge have how many etc. all will stand the check of practice.
Summary of the invention
For above-mentioned deficiency, the utility model provides a kind of twin spray gun.
The utility model is achieved through the following technical solutions: a kind of twin spray gun, comprises fluid pipe, airflow line, trunnion, shower nozzle, block, spray orifice; Fluid pipe is inner at airflow line, fluid pipe, airflow line coaxial line; Trunnion is at airflow line end, and shower nozzle is arranged on trunnion outside by screw thread, and block is fixed on shower nozzle bottom; Spray orifice is in shower nozzle bottom, and spray orifice is around block.
The usefulness of this utility model is: its atomizing principles is two-stage crushing+air mixing+gas current friction.When nozzle is normally worked, need the compressed air of feed spray gun certain pressure and the solution of certain pressure simultaneously, inner at spray gun, compressed air and solution pass through several times strike, mix, produce very little particle, compare with single-fluid spray gun, two-fluid spray gun is introduced after compressed air, not only can reduce the pressure of solution, and, the atomizing particle producing is tiny especially, and after atomization, particle is on average directly 80 microns, and drop total surface area increases several times.
Accompanying drawing explanation
Fig. 1: the utility model structural representation;
In figure: 1 fluid pipe, 2 airflow lines, 3 trunnions, 4 shower nozzles, 5 blocks, 6 spray orifices.
The specific embodiment
A twin spray gun, comprises fluid pipe 1, airflow line 2, trunnion 3, shower nozzle 4, block 5, spray orifice 6; Fluid pipe 1 is in airflow line 2 inside, fluid pipe 1, airflow line 2 coaxial lines; Trunnion 3 is at airflow line 2 ends, and shower nozzle 4 is arranged on trunnion 3 outsides by screw thread, and block 5 is fixed on shower nozzle 4 bottoms; Spray orifice 6 is in shower nozzle 4 bottoms, and spray orifice 6 is around block.Its atomizing principles is two-stage crushing+air mixing+gas current friction.When spray gun is normally worked, need the compressed air of feed spray gun certain pressure and the solution of certain pressure simultaneously, at the inner trunnion of spray gun 3 places, compressed air and solution pass through several times strike, mix, produce very little particle, compare with single-fluid spray gun, two-fluid spray gun is introduced after compressed air, not only can reduce the pressure of solution, and, the atomizing particle producing is tiny especially, and after atomization, particle is on average directly 80 microns, and drop total surface area increases several times.
