Description
Technical Field
The utility model relates to the technical field of energy recovery, in particular to a device for reducing steam loss.
Background
The steam entering the evaporation system is generally saturated steam, the steam enters a tubular heat exchanger and exchanges heat with materials, the temperature of the materials is increased by absorbing the vaporization latent heat of the steam, the evaporation effect is achieved, and new steam is condensed back into condensed water to enter the next working procedure. However, in the production process, due to control of the supersaturation degree of steam and influence of the heat exchange effect of the heat exchanger (such as unmatched heat exchange area, influence of scaling on the heat exchange effect and the like), some steam can not be condensed into condensate in time, and the steam-water mixed liquid is discharged together, so that the steam is wasted.
In the industrial salt preparation process, the purified salt solution is usually crystallized in an evaporation mode, so that sodium chloride solid is obtained. The vapor generated during the evaporation process is cooled and liquefied by a condenser and then is integrated into a pipe network. This has the following problems: when the steam discharge amount exceeds the rated cooling amount of the condenser, part of uncooled steam enters the pipe network, so that on one hand, the loss of the steam is caused, and on the other hand, the pressure of the pipe network is increased, so that potential safety hazards are caused.
Disclosure of Invention
In order to solve the above problems of the existing vapor condensing system, the present utility model provides a device for reducing vapor loss, so as to solve the above problems.
A device for reducing steam loss comprises an evaporation tank, a condenser, a water storage tank and a return pipeline; the top of the evaporation tank is provided with a steam pipeline; the steam pipeline is connected with the inlet of the condenser; the outlet of the condenser is connected with the inlet of the water storage tank; a water outlet pipeline is arranged at the bottom of the water storage tank; a drainage pump is arranged on the water outlet pipeline; the top of the water storage tank is provided with a return pipeline; the reflux pipeline is connected with the inlet of the condenser; the return pipeline is provided with a one-way valve.
Further, the water storage tank is provided with a liquid level meter; the liquid level meter is interlocked with the drainage pump; the level gauge is lower than the inlet of the water storage tank. When the liquid level in the water storage tank reaches the height of the liquid level meter, the drainage pump starts to drain water outwards, so that condensate water is prevented from recharging into the condenser due to the fact that the liquid level in the water storage tank is too high.
Further, one end of the water outlet pipeline, which is positioned at the water storage tank, is provided with a downward bent pipe, and the end part of the bent pipe is positioned above the bottom of the water storage tank. When the drain pump is used for conveying condensed water outwards, the drain pump is closed when the liquid level reaches the bent pipe, and the end part of the bent pipe can be sealed by the residual condensed water in the water storage tank to prevent uncooled steam from leaking outwards.
Further, a drain outlet is arranged at the bottom of the water storage tank.
Further, the condenser is a tube condenser.
Furthermore, the side wall of the water storage tank is provided with a viewing mirror at the position of the bent pipe.
The working principle of the utility model is as follows: the steam discharged from the evaporation tank is cooled in the condenser to become condensed water, the condensed water enters the water storage tank, the steam which is not thoroughly cooled enters the condenser again to be cooled by a return pipeline above the water storage tank, and the steam can be prevented from flowing back into the water storage tank by a one-way valve arranged on the return pipeline. The setting of the liquid level meter can monitor the liquid level in real time, and the condensate water is prevented from flowing backwards. The bent pipe can prevent uncooled steam from leaking.
The utility model has the beneficial effects that
Compared with the existing steam condensing equipment, the steam condensing equipment greatly reduces the loss of steam and also prevents the potential safety hazard of the rise of the pipe network pressure caused by the leakage of the steam into the water pipe network.
