Description
Technical field
The utility model relates to a kind of degassing vessel, relates in particular to a kind of degassing vessel that is applied in the sealing and circulating water system.
Background technology
In the sealing and circulating water system, it is most important to remove the gas that current are separated out in the system.If the gas of separating out in the sealing and circulating water system can not in time remove, then be easy to make in the system to produce two, cause system's heat exchange deleterious, even the heat exchange original paper is burnt etc., thereby cause great industrial accident.
At present, the degas method in the sealing and circulating water system generally is employed in the high point of system and automatic exhaust steam valve is set or degassing vessel is set.But; Degasifying effect in that the high point of system is provided with automatic exhaust steam valve is very poor; Especially the system that circulating water temperature is high, thermal load is big, the method that automatic exhaust steam valve is set at the height point can not satisfy the requirement of system's degassing, so the high point of the system that in these systems, is employed in usually is provided with the form of degassing vessel.
Generally the flow rate of water flow in the pipeline of sealing and circulating water system is higher, belongs to turbulent state, so the micro-bubble in the water can not float, can't from current, get rid of.And the principle of work of degassing vessel is: when current passed through degassing vessel, flow rate of water flow reduced, and makes the Reynolds number of current diminish, and current will be laminar flow regime.So, the mass force that the small bubbles that produce in the water receive will diminish, float to degassing vessel top and steep oneself-meeting in the buoyancy function therapeutic method to keep the adverse qi flowing downward, and at the final gas skirt that gets on the degassing vessel under the dual function of current and buoyancy.At last, the automatic exhaust steam valve that is provided with through the gas skirt top enters the gas that removes in the atmosphere, also can be drained in the expansion drum with the degassing vessel cooperating through vapor pipe, by the automatic valve that is provided with on the expansion drum gas that removes is entered atmosphere again.
Wherein, the significant parameter that relates to streamflow regime in the degassing vessel is a Reynolds number, when the Reynolds number of current less than 2000 the time, current will be in laminar flow regime.The calculation formula of Reynolds number is:
Re＝4*V*R/γ
The Re----Reynolds number;
The flow velocity of V-----water;
The coefficient of kinematic viscosity of γ----water;
The R-----hydraulic radius, R=A/ χ;
The A----discharge section area;
χ---water-carrying section wetted perimeter
Hence one can see that, as with Reynolds number as constant, the flow velocity of hydraulic radius and water will be inversely proportional to so, and hydraulic radius is directly proportional with the discharge section area of degassing vessel, be inversely proportional to the water-carrying section wetted perimeter of degassing vessel, so the area of tank body and flow velocity are inversely proportional to.Therefore, when wetted perimeter was constant, the tank body discharge section area of degassing vessel was big more, make current be in laminar flow regime, then needed the flow velocity of current just low more.
Existing degassing vessel generally by experience with the flow rate control of water in the degassing vessel at 0.1～0.5m/s; The problem that exists thus is exactly that the tank body size of calculating in the bigger sealing and circulating water system of quantity of circulating water is too big; And, after tank diameter surpasses certain numerical value, even flow rate of water flow is controlled in this scope; Current can not be in laminar flow regime, so very unfavorable for removing of bubble.
Summary of the invention
