The water spraying desuperheater has the characteristics of simple structure, large temperature adjusting range (up to 50-65 ℃), sensitive temperature adjustment and easy automation realization. The cooling water is sprayed into the water cooling device according to different structures, and the cooling water is divided into a Venturi type, a vortex type, a porous pipe type and the like. The existing Venturi type water spray desuperheater comprises an outer sleeve and an inner sleeve, wherein a section of Venturi tube is arranged at the inlet end of the inner sleeve, the inlet end of the inner sleeve is fixedly connected with the inner wall of the outer sleeve through a positioning block, a jacket is fixedly connected outside the middle section of the Venturi tube, a desuperheating water inlet pipe penetrates through the outer sleeve and the jacket, the inner end of the desuperheating water inlet pipe is fixedly connected with the jacket, and the Venturi tube in the jacket is provided with a plurality of water inlet holes; in the actual operation of the boiler, the water spray desuperheater is started when the temperature exceeds a designed value; when the water cooling device is opened, cooling water is injected into the inner sleeve through the temperature reduction water inlet pipe, steam in a pipeline is disturbed, the inner sleeve can generate strong vibration, and accidents such as fracture and the like easily occur at the joint of the temperature reduction water inlet pipe and the jacket.
Disclosure of Invention
The utility model aims at the above-mentioned not enough of prior art, provide a venturi type water spray desuperheater, it can reduce interior sheathed tube vibrations by a wide margin when pouring into the desuperheating water into, and the normal work of equipment is guaranteed for a long time in the emergence of accidents such as reducible desuperheating water inlet tube and clamp cover hookup department fracture.
In order to achieve the purpose, the utility model discloses a venturi formula water spray desuperheater, including outer sleeve, interior sleeve, the entrance point of interior sleeve is equipped with a section venturi, the entrance point of interior sleeve is connected with the outer sleeve inner wall through the locating piece is fixed, the middle section of venturi is connected with the jacket outward fixedly, a desuperheating water inlet pipe passes outer sleeve and jacket, the inner of desuperheating water inlet pipe is connected with the jacket fixedly, venturi in the jacket is equipped with several inlet openings; the method is characterized in that: more than two limiting blocks positioned on the same radial section are fixedly connected with the outer circle of the outlet end of the inner sleeve, and all the limiting blocks are fixedly connected with the inner wall of the outer sleeve in a welding manner.
The utility model has the advantages that the two ends of the inner sleeve are fixedly connected with the outer sleeve through the positioning block and the limiting block, so that the vibration of the inner sleeve can be greatly reduced when cooling water is injected, the accidents of fracture and the like of the joint of the temperature reduction water inlet pipe and the jacket can be reduced, and the normal work of the equipment can be ensured for a long time;
as a further improvement of the utility model, a plurality of supporting blocks are fixedly connected outside the inner sleeve between the limiting block and the Venturi tube, and the supporting blocks are tightly attached to the inner wall of the outer sleeve; the supporting block can limit the amplitude of vibration of the inner sleeve;
as a further improvement of the utility model, the inner end of the temperature-reducing water inlet pipe is fixedly connected with the jacket through a bushing; the lining can improve the strength and reduce the probability of fracture;
to sum up, the utility model discloses can reduce interior sheathed tube vibrations by a wide margin when pouring into the desuperheating water into, reducible desuperheating water inlet tube and the emergence of pressing from both sides accidents such as cover hookup department fracture guarantee the normal work of equipment for a long time.
