Abstract
The invention provides a drain flash tank for a heavy oil heater. The drain flash tank comprises a vertical tube body, wherein the upper and lower ends of the tube body are connected with end sockets, an steam outlet, a pressure meter port, a temperature meter port and a safety valve port are formed on the upper end socket of the tube body, and a drain outlet is formed on the bottom of the lower end socket of the tube body; a liquid level measuring device is arranged on the tube body, a manhole is formed in the side face of the tube body, a drain inlet with a water inlet pipe is formed on the lower part of the side face of the tube body, and the water inlet pipe is communicated with the tube body along the tangent line direction. Compared with the prior art, the drain flash tank has the advantages that as the manhole of the drain flash tank provided by the invention is formed in the side face of the tube body, workers are more convenient to overhaul and enter into the heavy oil heater; the water inlet pipe is communicated with the tube body in the tangent line direction, so that water current is distributed better.
Description
Technical field
The present invention relates to a kind of hydrophobic development unit, especially relate to a kind of drain flash tank for heavy oil heater.
Background technology
The effect of drain flash tank for heavy oil heater is that hydrophobic in pressure hydrophobic pipeline is carried out dilatation step-down, isolate steam and hydrophobic, steam is introduced in heavy fuel heater, make full use of its heat energy, hydrophobic, be introduced in drain tank and regularly send into water supply system.
In prior art, there is following defect in drain flash tank for heavy oil heater in use: level gauging inaccuracy; Manhole is located at upper cover, is not easy to the turnover of overhaul of the equipments and personnel; Water inlet pipe adopts radial connection, and water-flow equation effect is poor.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of level gauging more accurately, the drain flash tank for heavy oil heater of more convenient, the water inlet water-flow equation better effects if of inspection and maintenance.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of drain flash tank for heavy oil heater, it is characterized in that: it comprises vertical cylindrical shell, the upper and lower two ends of described cylindrical shell are connected with end socket, the upper cover of described cylindrical shell is provided with steam (vapor) outlet, pressure gauge port, thermometer mouth and relief valve port, and the bottom of the low head of described cylindrical shell is provided with hydrophobic outlet; Described cylindrical shell is provided with liquid level emasuring device, and the side of described cylindrical shell is also provided with manhole, and the side lower of described cylindrical shell is provided with the hydrophobic import with water inlet pipe, and described water inlet pipe is tangentially connected with described cylindrical shell.
Preferably, described pressure gauge port, described thermometer mouth and described relief valve port are arranged at intervals at circumferentially same.
More preferably, the center of circle of described same circumference is on the center line of described cylindrical shell.
More preferably, described upper cover is also provided with mouth for subsequent use, described in described mouth for subsequent use and described pressure gauge, thermometer mouth and described relief valve port are positioned at circumferentially same.
Preferably, described liquid level emasuring device is magnetic flap level gauge, and the top of described cylindrical shell is provided with measurement mouth, and bottom is provided with lower measurement mouth, be communicated with measuring tube between described upper measurement mouth and described lower measurement mouth, described magnetic flap level gauge is arranged on described measuring tube.
Preferably, described manhole is positioned at the top of described cylindrical shell.
More preferably, the open centre line direction of described manhole and the centerline direction of described water inlet pipe perpendicular.
Preferably, described low head is also provided with 3 along the spaced supporting leg of same even circumferential.
Owing to adopting technique scheme, compared to prior art, a kind of drain flash tank for heavy oil heater provided by the invention has the following advantages: manhole is provided with upper cover by (1) legacy equipment, and manhole is arranged at the side of cylindrical shell by the present invention, is more convenient for the turnover of maintenance of equipment and personnel; (2) water inlet pipe adopt tangential direction be connected with cylindrical shell, water inlet current along cylinder inboard wall screw current downflow, than conventional radial setting water inlet pipe water-flow equation better effects if; (3) liquid level emasuring device adopts magnetic flap level gauge, and this liquid level gauge has magnetostriction structure, more clear than the display of common liquid level gauge.
