Abstract
The invention relates to a spiral-flow type electric trap having an excellent gas uniform distribution effect. The existing electric traps for oil removal and defogging all adopt one or two layers of grid type gas uniform distribution plates for gas redistribution; such a structure causes uneven gas distribution or causes the gas speed to exceed the designed allowable speed in different degrees in the practice process; and bad gas uniform distribution effect can result in uneven gas flow rate in each precipitating polar tube; as a result, the gas flow velocity in partial tubes is overhigh and the gas purification efficiency is low; and more seriously, the rona electrode can be impacted to swing in the precipitating polar tube so that the equipment is incapable of operating normally. The spiral-flow type electric trap having the excellent gas uniform distribution effect comprises a barrel, wherein an intake chamber is arranged in the barrel; a first layer of distribution plates and a second layer of distribution plates are arranged in the intake chamber; and the spiral-flow type electric trap having the excellent gas uniform distribution effect is characterized in that a diffusion tube and a disturbance tube communicated with each other are arranged under the first layer of distribution plates. The spiral-flow type electric trap having excellent gas uniform distribution effect is simple in structure, convenient to manufacture and mount, and capable of achieving good gas uniform distribution effect.
Description
Technical field
The present invention relates to a kind of electric trapper, especially relate to the spiral-flow type electric trapper with the uniform effect of good gas.
Background technology
Oil removing demist electric trapper all adopts one deck or two-layer grid type even gas distribution plate enforcement gas to distribute again at present, this kind structure occurs in various degree the distribution of gas inequality in practice process or gas velocity surpasses design speed allowable, the bad meeting of even gas distribution effect causes by the gas flow in every receiving electrode pipe unbalanced, thereby cause in local pipe the too fast gas purification efficient of gas flow rate not high, can swing in the receiving electrode pipe by the impulse corona utmost point when serious, equipment can't normally move.
Summary of the invention
It is more even that technical problem to be solved by this invention is to provide a kind of distribution of gas that makes, and can satisfy the stronger spiral-flow type electric trapper of various working and adaptability.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of spiral-flow type electric trapper with the uniform effect of good gas, comprise cylindrical shell, be provided with inlet chamber in described cylindrical shell, be provided with one deck distribution grid and two layers of distribution grid in described inlet chamber, its special feature is: be provided with anemostat and the disturbed flow pipe that is interconnected below described one deck distribution grid.
Described anemostat is open circles bench-type anemostat, comprise diffusion end and inlet end, disturbed flow pipe is the straight tube disturbed flow pipe, the diameter of described disturbed flow pipe is identical with anemostat inlet end diameter, the diffusion end of described anemostat is arranged on the cylinder inboard wall of one deck distribution grid bottom, and the end of described disturbed flow pipe and the inlet end of described anemostat are tightly connected.
The diameter of described disturbed flow pipe is not less than 1/2nd of barrel diameter, and the disturbed flow pipe mouth of pipe is positioned at not 1/3rd places higher than the air inlet height.
The axis of described anemostat and disturbed flow pipe all coincides with tubular axis.
compared with prior art, beneficial effect of the present invention is: be provided with disturbed flow pipe and the anemostat that is interconnected due to inlet chamber of the present invention, and be arranged on the bottom of one deck distribution grid, gas is not directly to carry out even gas distribution by one deck distribution grid but concentrate to converge through the straight tube disturbed flow pipe again spreading by entering anemostat in the middle part of the straight tube disturbed flow pipe after entering inlet chamber, pass through again the distribution effect of one deck distribution grid and two layers of distribution grid, like this with regard to avoided gas by distribution grid the time because distribution grid forms the gas Biased flow phenomenon apart from the difference of air inlet position, guarantee as far as possible to be consistent by the gas velocity of receiving electrode pipe, minimizing is because of the impact of the too fast target suspension of local gas velocity in cylindrical shell, the difficult swing of corona wire in the receiving electrode pipe, thereby improve gas purification efficient, assurance equipment normally moves, having reduced simultaneously gas velocity in local pipe, to make the tar fog of gas drop in the receiving electrode intraductal retention time longer, increased the corona arresting efficiency.
