Abstract
The utility model relates to sewage discharging systems, in particular to a sewage discharging system for a negative pressure pipeline. The sewage discharging system solves the problems of low efficiency and time and labor wasting when an existing negative pressure pipeline discharges sewage. The sewage discharging system comprises a U-shaped negative pressure pipeline, and a sewage discharging pipeline communicated with the negative pressure pipeline is arranged at the bottom of the negative pressure pipeline. A control valve is arranged on the sewage discharging pipeline, a sewage discharging seal tank is arranged below the sewage discharging pipeline, the lower portion of the sewage discharging seal tank extends into water, and an overflow pipe communicated with the sewage discharging seal tank is arranged on the lateral wall of the sewage discharging seal tank. The sewage discharging system for the negative pressure pipeline is reasonable and reliable in structural design, achieves automatic sewage discharging through sewage liquid gravity, prevents air from entering a negative pressure pipeline, reduces labor strength while improves operation efficiency, and has the advantages of being simple in structure, convenient to operate and low in cost.
Description
Technical field
The utility model relates to chemical industry drainage, is specially a kind of negative-pressure pipeline drainage.
Background technology
Chemical Manufacture process conditions are complicated, and section of tubing or internal tank are negative pressure, and the inner liquid generating is difficult to discharge smoothly, and conventional method for discharging pollution exists wastes time and energy and the problem of inefficiency.
Summary of the invention
The utility model exists when solving existing negative-pressure pipeline blowdown wastes time and energy and the problem of inefficiency, and a kind of negative-pressure pipeline drainage is provided.
The utility model is to adopt following technical scheme to realize: negative-pressure pipeline drainage, comprise U-shaped negative-pressure pipeline, the bottom of negative-pressure pipeline is provided with the blow-off line being communicated with it, on blow-off line, be provided with control valve, and blow-off line below is provided with its underpart and stretches into the sewer sealing groove in water, and the sidewall of sewer sealing groove is provided with the bleed off pipe communicating with it.
In running, rely on soiling solution gravity in negative-pressure pipeline, automatically flow out negative-pressure container, and can keep lastingly certain liquid level, prevent that air from entering negative-pressure pipeline, while having overcome existing negative-pressure pipeline blowdown, exist and waste time and energy and the problem of inefficiency.
The utility model reasonable in design is reliable, utilizes soiling solution gravity to realize automatic pollution discharge, and prevents that air from entering negative-pressure pipeline, when reducing labor intensity, has improved operating efficiency, has advantages of simple in structure, easy to operate and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-negative-pressure pipeline, 2-blow-off line, 3-control valve, 4-sewer sealing groove, 5-bleed off pipe.
The specific embodiment
Negative-pressure pipeline drainage, comprise U-shaped negative-pressure pipeline 1, the bottom of negative-pressure pipeline 1 is provided with the blow-off line 2 being communicated with it, on blow-off line 2, be provided with control valve 3, and blow-off line 2 belows are provided with its underpart and stretch into the sewer sealing groove 4 in water, the sidewall of sewer sealing groove 4 is provided with the bleed off pipe 5 communicating with it.
In specific implementation process, the material of blow-off line 2 is that metal or hard rubber or other are difficult for being taken out flat material and make, and during installation, require good seal is installed, otherwise it is inner and cannot the interior hydrops of ejector easily to make air enter negative-pressure container.
Pressure in running in negative-pressure container is dynamic fluctuation, for guaranteeing the thorough emptying of liquid in container, conventionally require H > P(maximum)/ρ g, as occurred barotropic condition in negative container, for preventing that container inner medium from leaking outside, can lengthen the height below liquid level in blow-off pipe insertion water sealed tank.
H refer to that blow-off line 2 picks out a little and sewer sealing groove 4 bleed off pipes 5 between vertical height;
P is the vacuum in negative-pressure pipeline 1;
ρ is the density of sewage;
G is local gravitational acceleration.
