Description
Technical field
The present invention relates to a kind of industry boiler energy-conservation blowdown apparatus.
Background technology
Industrial Boiler is industrial heart, in a large amount of evaporations of boiler water, having impurity separates out at the liquid level place of drum and condenses, in order to prevent that a large amount of dirts are at boiler and drum encrustation, the water on drum surface must be discharged continuously, the platoon system of Here it is boiler, traditional platoon stove water is through the flash distillation of boiler flash vessel, indirect steam is used thermal deaerator, and a large amount of condensate water are drained.The blowdown rate of station boiler is 0.3-1%, the general industry boiler blowdown rate is 3-10%, so just having a large amount of current loses, the more important thing is the heat-energy losses with the water of heat energy, the value of loss heat energy is the 30-50 that itself is worth times of water, cause the significant wastage of water and the energy, be a great problem that Industrial Boiler is saved water and energy and produced always.
The industry boiler energy-conservation waste removal equipment, it is exactly the new equipment according to the drawback problem research and development of above existence, utilize boiler overheating steam as the energy of equipment rotation and the evaporation of platoon stove water, take blade structure and free settling effect, the auger of dirt below equipment discharged, fundamentally solved wasting water and the drawback of the energy of Industrial Boiler blowdown, that guarantees boiler platoon stove water can regulate cleaning automatically, guarantees efficient, the safe operation of boiler.
Summary of the invention
The objective of the invention is to overcome problems of the prior art, a kind of industry boiler energy-conservation blowdown apparatus is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of industry boiler energy-conservation blowdown apparatus comprises housing, turbine apparatus, steam heater, conveying worm; Steam heater is installed on hull outside, is connected with the side of housing; Conveying worm is installed on the below of housing; Described turbine apparatus is arranged in the housing; Turbine apparatus comprises turbine vane, and the top of turbine vane is equipped with steam jet; The turning cylinder of turbine vane connects reductor by magnetic shaft coupling, and the reductor bottom connects the scraper plate power transmission shaft; On the scraper plate power transmission shaft scraper stent is installed, the outer end of scraper stent connects scraper plate; The rotating shaft of conveying worm connects the scraper plate power transmission shaft by driving chain, rotates synchronously with the scraper plate power transmission shaft.
Industry boiler energy-conservation blowdown apparatus of the present invention is saved water and energy, and blows three groups of turbines by Boiler Steam, and turbine drives scraper plate and following helix transporting device, does not need external power supply, effectively solves the draining waste of conventional boiler flash vessel, and the loss of heat energy; Reduce blowdown rate and the rate of water make-up of boiler, avoided the waste of water and the heat energy of traditional flash vessel equipment, brought significant energy-saving and emission-reduction benefit to enterprise.
The description of drawings book
Fig. 1 is the structural representation of industry boiler energy-conservation blowdown apparatus of the present invention;
The specific embodiment
The top of turbine vane 4 is equipped with steam kuppe 13, and described steam kuppe 13 is fixed in the top of housing, is connected with steam (vapor) outlet
The top of housing 2 is equipped with steam deflection plate 3, and the steam deflection plate is positioned at the top of steam kuppe 13, is connected with steam (vapor) outlet.
The top of conveying worm communicates with the bottom of turbine apparatus.
End at conveying worm is equipped with electric control valve 12, is used for the discharging of control dirt.
Boiler platoon stove water is introduced this device by steam heater, and the stove water that utilizes on the one hand superheated steam will tangentially flow in the housing evaporates, and produces indirect steam, and the solid-state dirt that stays in the stove water is discharged by scraper plate and conveying worm; Utilize on the one hand the kinetic energy of steam to drive the turbine vane rotation, turbine vane drives scraper plate again and conveying worm rotates, and sees off scraping, be deposited on following mud strand; Low-pressure steam flows out through steam deflection plate and steam kuppe, goes the low-pressure steam production system to use; Perhaps the moisturizing with boiler mixes, and the heating moisturizing is with energy recovery.Low-pressure steam outlet is arranged on steam kuppe top, and the clean steam flush that following saturated vapor comes up and scattered by turbine vane blows to the housing side with the solid content of carrying secretly, is struck off by scraper plate, guarantees the cleaning of the low-pressure steam that flows out.
Scraper plate is close to shell inner surface and is rotated, and the lower end of scraper plate power transmission shaft is the conveying worm of band strand sheet, and by scraper plate, settlement action, the conveying worm mud strand that the evaporation of stove water is remaining is seen off.The electric control valve of discharging mud can be regulated blowdown rate according to the traffic requirement of stove water water quality and steam, can control the moisture content of mud.Adopt electric control valve to connect the PLC unit of automatically monitoring and control, under the prerequisite that guarantees stove water water quality and steam production, reduce the discharge of water as far as possible, take the mud of discharging thickness as optimum state, to reach the loss of saving stove water and reducing heat energy, save production cost, particularly can realize full-automatic PLC production control, reduce labour intensity, realize the boiler blow-off automation, can regulate, high efficiency, guarantee that boiler has significant energy-saving and emission-reduction benefit.
Embodiment 2 adopts industry boiler energy-conservation blowdown apparatus of the present invention that the DZL4-1.25-4 steam boiler of Qingdao Jiarun chemical company is carried out the blowdown processing, moves 6 months, and the front and back Contrast on effect is as follows:
