Abstract
A desulfurizing and smoke removal chimney comprises a desulfurizer and a smoke removal cylinder arranged above the desulfurizer. The smoke removal cylinder is connected with the desulfurizer through a conical segment. A water removal structure is arranged at a smoke inlet of the smoke removal cylinder and composed of a central tube and a guide rotating plate. The guide rotating plate is mounted on the central tube at a mounting lift angle of 10-90 degrees. The desulfurizing and smoke removal chimney has the advantages that smoke heat energy and kinetic energy are low in loss, lifting capacity is high, energy conservation is effective, the cylinder is anticorrosion and production cost is low. Through the desulfurizing and smoke removal chimney, the present problems of acid precipitation and chimney liner corrosion during online operation of the chimney are solved.
Description
Technical field
The present invention relates to a kind of chimney, especially relate to the chimney of a kind of desulfurization and smoke evacuation functional unification.
Background technology
In the face of the later fume emission problem of wet desulphurization, a kind of scheme that relevant enterprise such as China's metallurgy, chemical industry and thermoelectricity adopts is that the chimney that makes up certain altitude at the desulfurizing tower top discharges, with build chimney separately and compare, this scheme has that the flue gas passage of flowing through is short, and heat energy and the kinetic energy rejection of flue gas are little, and the lifting ability is strong, good energy-conserving effect, therefore advantages such as construction cost is low, are widely adopted.
But because the height that chimney makes up at the desulfurizing tower top is generally not high, the height of release of flue gas is low, and is moisture in the flue gas in addition, thereby brings " acid rain " problem to environment, and particularly in temperature low winter, problem is comparatively serious.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of not only flue gas heat energy and kinetic energy rejection little, and the lifting ability is strong, good energy-conserving effect, and construction cost is low, and can effectively solve the chimney of desulfurization with the smoke evacuation functional unification of serious acid rain problem.
The technical solution adopted for the present invention to solve the technical problems is: the chimney of a kind of desulfurization and smoke evacuation functional unification, comprise desulfurizing tower and smoke evacuation cylindrical shell, described smoke evacuation cylindrical shell is located at the top of desulfurizing tower, link to each other with desulfurizing tower by the awl section, the gas approach place of described smoke evacuation cylindrical shell is provided with except water-bound, described except water-bound by central tube with lead rotating plate and forms, the described rotating plate of leading is installed on the central tube, the installation lift angle is 10～90
o(preferred 50～70
o, more preferably 60
o).
Further, the described rotating plate of leading is 4～8.
Further, described central tube is hollow pipe.
Further, the liner of described smoke evacuation cylindrical shell is provided with helix structure except the surface, top of water-bound, and described helix structure is that the cross section is
LThe strip structure of type,
LThe type angle is 60～90
o(preferred 65-75
o)
, highly≤150mm.
Further, the quantity of described helix structure is 4～16, and tilt angle is 45～90
o(preferred 60-70
o).
Further, describedly made by acid-resistant anti-corrosion materials such as fiberglass except water-bound, helix structure.
Utilize the present invention, can make flow of flue gas by the original circumferential flow of axially changing into, utilize the principle of the centrifugal force of rotation flue gas, inertia force that flow direction changes and droplet collision, cohesion, adhesion to reduce moisture in the flue gas significantly, after this discharge chimney in rotary manner, can efficient solution remove the Fundamentals that acid rain takes place, advantages such as having does not have corrosion, and environment protecting is good, and cost is low.

Fig. 2 is the enlarged diagram except water-bound embodiment illustrated in fig. 1.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, present embodiment comprises desulfurizing tower 1 and smoke evacuation cylindrical shell 4, described smoke evacuation cylindrical shell 4 is located at the top of desulfurizing tower 1, link to each other with desulfurizing tower 1 by awl section 2, the gas approach place of described smoke evacuation cylindrical shell 4 is provided with except water-bound 3, described except water-bound 3 by central tube 7 with lead rotating plate 6 and forms, the described rotating plate 6 of leading is installed on the central tube 7, the installation lift angle is 60
o, the described rotating plate 6 of leading is 4; Described central tube 7 is hollow pipe; The liner of described smoke evacuation cylindrical shell 4 is provided with helix structure 5 except the surface, top of water-bound, and described helix structure 5 is that the cross section is
LThe strip structure of type,
LThe type angle is 75
o, height 120mm; The quantity of described helix structure 5 is 8, and tilt angle is 60
o
Describedly make by fiberglass except water-bound 3, helix structure 5, certainly, also can be made by other acid-resistant anti-corrosion material.
