Technical field
The utility model relates to heat power plant boiler water supply system, is specifically related to the dispenser in a kind of heat power plant boiler water supply system.
Background technology
The boiler feed water in thermal power plant requires very high, need to add a lot of medicaments, for example adds hydrazine, carries out chemical deoxidization.The medicament of buying is all high concentration, needs before use it to dilute in proportion, therefore need to first make up a prescription.
The boiler feed water dispenser in existing thermal power plant, mainly formed by an injector, a medicament cartridge and the chemical tank that configures, described injector adopts venturi principle design, it comprises a pedestal, import is established in one end of pedestal, the other end sets out mouth, pedestal inside is communicated with a tubular cavity from import to outlet, this tubular cavity forms by introducing section, converging transition, trunnion section and divergent segment successively from import to outlet, insert a jet pipe from pedestal import towards introducing in section, this jet pipe forms a nozzle towards the end convergent in pedestal; And the convergent place facing to jet pipe on pedestal is provided with medicament entrance; Described medicament entrance connects medicament cartridge by the road, and described jet pipe connects dilution water, and described outlet connects the chemical tank configuring by the road.
There is following defect in above-mentioned prior art: the injection of injector can not be adjusted than fixing, thereby cause the dilution ratio of medicament to be not easy to regulate, and the existing practice is the injector of configuration plurality of specifications, drops into larger.
Summary of the invention
The purpose of this utility model is to provide the dispenser in a kind of heat power plant boiler water supply system, can not adjust, thereby cause the ratio of making up a prescription to be not easy to the problem regulating to solve the injection of prior art injector than fixing.
For achieving the above object, the technical solution adopted in the utility model is:
Dispenser in a kind of heat power plant boiler water supply system, comprise injector, medicament cartridge and the chemical tank configuring, injector comprises a pedestal, import is established in one end of pedestal, the other end sets out mouth, and pedestal inside is communicated with a tubular cavity from import to outlet, and this tubular cavity forms by introducing section, converging transition, trunnion section and divergent segment successively from import to outlet, insert a jet pipe from pedestal import towards introducing in section, this jet pipe forms a nozzle towards the end convergent in pedestal; And the convergent place facing to jet pipe on pedestal is provided with medicament entrance; Described medicament entrance connects medicament cartridge by the road, and described outlet connects the chemical tank configuring by the road; A straight section is extended at described nozzle place, on this straight section, establishes internal thread, in described trunnion section, also establishes internal thread; Corresponding straight section is provided with one first loop pipe, on this first loop pipe, establishes external screw thread, and the first loop pipe embeds in straight section and is threaded with straight section; Corresponding trunnion section is provided with one second loop pipe, on this second loop pipe, establishes external screw thread, and the second loop pipe embeds in trunnion section and is threaded with trunnion section.
Owing to having adopted technique scheme, the utlity model has following advantage:
The utility model by arranging the first loop pipe in the nozzle of injector, the second loop pipe is set in trunnion section, and the first loop pipe and the second loop pipe are and are threaded, can change easily, by changing the first loop pipe and second loop pipe of different pore size, equal to have regulated the bore of nozzle and trunnion section, reach and adjust the object of spraying ratio, the utility model injector can be general, in the time wanting regulating agent dilution ratio, only need to change the first loop pipe and the second loop pipe, reduced input cost.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is injector interior structural representation of the present utility model.
In above accompanying drawing: 1, injector; 2, medicament cartridge; 3, the chemical tank configuring; 4, pedestal; 5, import; 6, outlet; 7, introduce section; 8, converging transition; 9, trunnion section; 10, divergent segment; 11, jet pipe; 12; Nozzle; 13, medicament entrance; 14, the first loop pipe; 15, the second loop pipe.
The specific embodiment
