Abstract
The invention discloses an adjustable vapor generator overvoltage protecting device. On the basis of an existing vapor generating device comprising an emptying pipeline (1), a vapor output pipe (2), a pressure sensor (3), a temperature sensor (4), a vapor tank (5) and a heater (7), a lateral branch pipe extending deeply under the liquid level in a liquid seal pipe (9) to approach the bottom is arranged on the side of the vapor tank (5), and a graduated scale (11) is disposed on a liquid level meter (10) disposed on the side of the liquid seal pipe (9). The adjustable vapor generator overvoltage protecting device has the advantages that vapor outlet pressure is controlled by liquid level, accurate conversion of liquid pressure intensity and liquid column height can be achieved, vapor outlet pressure can be set fast and accurately, when vapor leaks, liquid can cool and liquefy the vapor or absorb the same, and safety problems caused by the fact that the high-temperature vapor is discharged to a lab space can be avoided effectively.
Description
Technical field
The invention belongs to integrated form Experiment of Principles of Chemical Engineering actual training device technical field; what relate generally to is a kind of adjustable steam generator over-pressure safety device, in particular, and by setting the liquid level position of steam outlet; control steam and release pressure, protective device even running.
Background technology
At present; in the experimental provision of numerous use steam generators; its pressure protect is all to use mechanical compression protective device; directly high-temperature steam is discharged into experimental implementation space during steam generator hypertonia thus, has potential safety hazard, the value of pressure release is simultaneously set does not have explicit data; need to start system attempts gradually; and mechanical device easily breaks down because of corrosion, obstruction, complicated operation, danger are difficult in maintenance.
Summary of the invention
For overcoming above drawback, the object of this invention is to provide a kind of adjustable steam generator over-pressure safety device, ensure the security in experiment, the simplicity of operation.
For achieving the above object, the technical solution used in the present invention is: it is on the architecture basics of the existing steam generator device mainly consisting of steam tank body, pressure sensor, temperature sensor, heater and fluid circuit, on steam generator top, draw pipeline, insert a vertical uncovered extra heavy pipe bottom, be called liquid sealing pipe, in liquid sealing pipe, pack liquid into, Liquid level adjusting valve is joined in bottom, and there are transparent liquid level gauge and corresponding rule in outside.
The invention has the beneficial effects as follows, by liquid level, control steam exit pressure, liquid pressure and liquid-column height can accurately convert, can set out steam exit pressure fast and accurately, when steam releases simultaneously, liquid can or absorb steam cooling liquefaction, has effectively avoided high-temperature steam to be discharged into the safety problem that lab space causes.
Accompanying drawing explanation
Figure is steam generator over-pressure safety device operation principle schematic diagram of the present invention.
In figure: 1, blowdown piping, 2, steam output pipe road, 3, pressure sensor, 4, temperature sensor, 5, steam tank body, 6, liquid level sensor, 7, heater, 8, Liquid level adjusting valve, 9, liquid sealing pipe, 10, liquid level gauge, 11, rule
The specific embodiment
By reference to the accompanying drawings, provide embodiments of the invention as follows, but the present invention is not limited to following examples:
As shown in the figure, adjustable steam generator over-pressure safety device comprises blowdown piping 1, steam output pipe 2, pressure sensor 3, steam tank body 5, heater 7, Liquid level adjusting valve 8, liquid sealing pipe 9, liquid level gauge 10, rule 11 and the pipeline being comprised of multistage stainless steel pipeline.
Steam tank body is stainless steel, be of a size of Φ 600 * 800mm, be oval stainless steel end socket up and down, vertically be fixed on framework, tank body upper end is fixed with blowdown piping 1, steam output pipe road 2, pressure sensor 3, temperature sensor 4, blowdown piping and steam output pipe road are to be controlled by the stainless steel ball valve being threaded, pipeline and tank body welding before valve, pressure sensor 3 and temperature sensor 4 are threaded connection on the hickey of tank body, measure steam pressure and fluid temperature in tank body, the liquid level sensor of tank body is connected with the upper and lower sides arm of tank body by flange, measure liquid level in tank body, below, tank body rear flank is provided with three groups of electric heaters, in order to heating liquid, produce steam, tank body side is near upper cover position, be welded with side branch, in this example, arm is Φ 25 stainless steel tubes, the arm other end is inserted into liquid sealing pipe 9 above 20mm places, bottom, liquid sealing pipe 9 is Φ 51 * 800mm stainless steel tube, vertically be fixed on framework, side elevation by-pass connects liquid level gauge 10, rule 11 is fixed on liquid level gauge 10, scale starting point flushes with the arm lower end of going deep into liquid sealing pipe 9, scale value on rule 11 has been scaled pressure number, according to liquid level, can directly read pressure, liquid sealing pipe 11 bottoms are communicated with Liquid level adjusting valve 8, according to requirement of experiment, accurately regulate at any time liquid level, regulate protection force value.When the present invention uses, in liquid sealing pipe, add liquid, in this example, make water, by control valve, control liquid level to protection force value.Steam tank body adds water, closes atmospheric valve, and heater via is heated to uniform temperature; open and produce steam, other container transport steam of steam pipeline road direction, steam pressure constantly rises with heating; when pressure surpasses protection force value, under liquid sealing pipe liquid level, there is steam to emit, liquid level has slight fluctuations.Regulate heater power, keep liquid sealing pipe liquid level always in slight fluctuations state, now steam generator internal vapor pressure is set definite value.
Claims (2)
1. an adjustable steam generator over-pressure safety device; comprise blowdown piping (1), steam output pipe (2), pressure sensor (3), temperature sensor (4), steam tank body (5), heater (7); it is characterized in that: side branch is set in described steam tank body (5) side and gos deep in liquid sealing pipe (9) under liquid level, near bottom, on the liquid level gauge (10) that liquid sealing pipe (9) side arranges, being provided with rule (11).
2. a kind of adjustable steam generator over-pressure safety device according to claim 1, is characterized in that: the scale of described rule (11) has been scaled pressure values, and scale starting point flushes with the arm lower end of going deep into liquid sealing pipe 9.
