Abstract
The utility model discloses an anti-pollution device which utilizes a venturi tube in chloromethane production. A water outlet of a water tank (4) is connected with an input opening of a centrifugal pump (5), a three-way valve (7) is arranged at an output opening of the centrifugal pump (5), the output opening of the centrifugal pump (5) is respectively communicated with an opening I of the venturi tube (3) and a dilute hydrochloric acid storage tank (6) by virtue of the three-way valve (7), an opening II of the venturi tube (3) is in two-way communication with an inlet/outlet I of one end of a negative pressure tank (2), an inlet/outlet II of the other end of the negative pressure tank (2) is communicated with a stuffing box of an exhaust chamber of a chloromethane compressor (1), and a water outlet of the venturi tube (3) is communicated with a water inlet of the water tank (4). When gas in the stuffing box needs to be sucked to form dilute hydrochloric acid, the output opening of the centrifugal pump (5) is communicated with the opening I of the venturi tube (3), and when the dilute hydrochloric acid needs to be conveyed to the dilute hydrochloric acid storage tank (6), the output opening of the centrifugal pump (5) is communicated with the dilute hydrochloric acid storage tank (6).
Description
Technical field
The utility model relates to a kind of environmental control system that utilizes Venturi tube in producing chloromethanes.
Background technology
In chloromethanes production process, use piston compressor, by the reciprocating motion of piston, will after methyl chloride gas compression, carry out condensation.Compressor is in use because hydrogen chloride produces corrosion to axle, make the rough of axle, rough axle produces wearing and tearing to airtight and watertight padding under high-speed cruising, reduce the sealing effectiveness of filler, cause material to leak out from the stuffing-box of compressor air-discharging chamber, thereby bring environmental pollution and etching problem.
Summary of the invention
The utility model provides a kind of environmental control system that utilizes Venturi tube in producing chloromethanes, and it avoids occurring the environmental pollution because of sealing leak generation.
The utility model has adopted following technical scheme: a kind of environmental control system that utilizes Venturi tube in producing chloromethanes, it comprises chloromethanes compressor, negative-pressure cup, Venturi tube, water tank and centrifugal pump, the delivery port of water tank is connected with the input port of centrifugal pump, the delivery outlet of centrifugal pump is provided with triple valve, the delivery outlet of centrifugal pump is communicated with opening I and the watery hydrochloric acid storage tank of Venturi tube respectively by triple valve, the opening II of Venturi tube and the import/export I of negative-pressure cup one end are diconnected, the import/export II of the negative-pressure cup other end is connected with the stuffing-box of chloromethanes compressor air-discharging chamber, the discharge outlet of Venturi tube is connected with the water inlet of water tank, in the time need to sucking the gas formation watery hydrochloric acid of stuffing-box, the delivery outlet of centrifugal pump is connected with the opening I of Venturi tube, when needs are carried watery hydrochloric acid to watery hydrochloric acid storage tank, the delivery outlet of centrifugal pump is connected with watery hydrochloric acid storage tank.
Described chloromethanes compressor is set to piston compressor.Described Venturi tube is set to water-jet pump.Described centrifugal pump is fluorine alloy pump.
The utlity model has following beneficial effect: adopted after above technical scheme, the water that the interior injection of the utility model water tank 4 is certain, in centrifugal pump 5 enters Venturi tube 3, high velocity jet by water makes the interior formation negative pressure of negative-pressure cup 2, by the gas negative suction tank 2 leaking out the stuffing-box from chloromethanes compressor 1 exhaust chamber, in Venturi tube 3 with water circulation blended absorbent, form watery hydrochloric acid, after reaching finite concentration, circulation absorption is transported to watery hydrochloric acid storage tank 6, then the water in cyclic water tank 4 is supplied, can prevent like this because environmental pollution and the corrosion that chloromethanes compressor leakage brings.
