Abstract
The utility model relates to chemical evacuation equipment which comprises a water jet pump. The water jet pump is composed of a nozzle, a suction chamber and a diffusion tube sequentially connected with one another in series; and the suction chamber of the water jet pump is communicated with the chemical equipment in need of evacuation. The innovative point of the chemical evacuation equipment lies in that a water outlet at the end of the diffusion tube is connected with a water inlet at the front end of the nozzle by a circulating pipeline. The chemical evacuation equipment has the following advantages: when in use, medium water is ejected out from the nozzle at high speed, and gas in the suction chamber and the chemical equipment communicated with the suction chamber is forced to be carried by and mixed with high-speed jet flow, so as to form gas-liquid mixed flow entering the diffusion tube, thereby reducing the pressure in the suction chamber and the chemical equipment, and realizing the evacuation. After being dissolved in the medium water, harmful impurities in the chemical equipment are discharged from the water outlet of the diffusion tube, and flow back to the water inlet of the nozzle from the circulating pipeline for recycling use without external leakage, thereby avoiding environmental pollution.
Description
Technical field
The utility model relates to a kind of chemical industry vaccum-pumping equipment, particularly a kind of chemical industry vaccum-pumping equipment of environmental protection.
Background technique
In Chemical Manufacture, often need to adopt vacuum pump that equipment is vacuumized, traditional chemical industry vaccum-pumping equipment is a water jet pump, it is by the nozzle that is connected in series successively, suction chamber and diffusing tube constitute, its working principle is: the working medium water with certain pressure, water intake by spray nozzle front end enters nozzle, under the effect of nozzle, spray at a high speed to the suction chamber that is communicated with nozzle, gas in the suction chamber is forced to carry with it by high-speed jet and is mixed, and forms gas-liquid mixed stream, enters diffusing tube, thereby suction chamber pressure is reduced, form vacuum, realization vacuumizes equipment, and the kinetic energy of mixed jet changes the pressure energy into, speed reduces pressure and raises, gas is further compressed, and outside the water excavationg pump, gas release is gone into atmosphere through the terminal water outlet of diffusing tube.Objectionable impurities in the chemical industry equipment is dissolved in the WATER AS FLOW MEDIUM with outside its excavationg pump, is released in the air, pollutes.
The model utility content
The technical problems to be solved in the utility model provides a kind of chemical industry vaccum-pumping equipment of environmental protection.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of chemical industry vaccum-pumping equipment, comprise water jet pump, this water jet pump is by nozzle, suction chamber and the diffusing tube of serial connection constitute successively, the suction chamber of described water jet pump is communicated with the chemical industry equipment that need vacuumize, and its innovative point is: the water outlet of described diffusing tube end is connected with the front end water intake of nozzle by circulating line.
Advantage of the present utility model is: during use, WATER AS FLOW MEDIUM sprays at a high speed by nozzle, suction chamber and forced to carry with it by high-speed jet and mix with the gas in the chemical industry equipment that suction chamber is communicated with, forming gas-liquid mixed flows to into diffusing tube, thereby reduce the pressure in suction chamber and the chemical industry equipment, realize vacuumizing.After objectionable impurities is dissolved in the WATER AS FLOW MEDIUM in the chemical industry equipment, discharge from water outlet of diffusing tube, and be back to the nozzle water intake by circulating line and recycle, do not exist and leak, avoided the pollution of environment with it.
Description of drawings
Accompanying drawing is the utility model chemical industry vaccum-pumping equipment structural representation.
Embodiment
As shown in drawings, the utility model relates to a kind of chemical industry vaccum-pumping equipment, comprise water jet pump 1, this water jet pump 1 is by nozzle 1a, suction chamber 1b and the diffusing tube 1c of serial connection form successively, the front end of nozzle 1a is a water intake, the end of diffusing tube 1c is a water outlet, and suction chamber 1b is communicated with the chemical industry equipment that need vacuumize, and the water outlet of diffusing tube 1c end is connected with the front end water intake of nozzle 1a by circulating line 2.
During use, WATER AS FLOW MEDIUM enters nozzle 1c by water intake, suction chamber 1b and forced to carry with it by high-speed jet and mix with the gas in the chemical industry equipment 3 that suction chamber 1b is communicated with, forming gas-liquid mixed flows to into diffusing tube 1c, thereby reduce the pressure in suction chamber 1b and the chemical industry equipment, realize vacuumizing.After objectionable impurities is dissolved in the WATER AS FLOW MEDIUM in the chemical industry equipment, discharge from water outlet of diffusing tube, and be back to nozzle 1a water intake by circulating line 2 and recycle, do not exist and leak with it.
Claims (1)
