Technical field
The utility model relates to condensed water elimination field, specifically a kind of tobacco extraction liquid evaporation concentrator condensate drain.
Background technology
In tobacco extraction liquid evaporation concentrator, the effect of both vapor compression blower fan is, compresses the indirect steam produced during material evaporation, and the steam after compression becomes the thermal source of system evaporation.In vapor compression process, in the air channel before inspissator blower fan, condensed water being produced, intaking for preventing blower fan; when condensed water elimination causes liquid level too high not in time; protection switch can make fan parking, to protect blower fan, will have influence on evaporation concentrator like this and normally work.
At present, the scheme of above-mentioned liquid evaporation concentrator being carried out at work to condensed water elimination is: be connected to a collecting tank in bottom, air channel, the top and the bottom of this collecting tank have been equipped with high liquid level sensor, low liquid level sensor respectively, are connected with pipeline and centrifugal multistage pump multiple centrifugal pump bottom this collecting tank.Its operation principle is, when condensed water reaches high liquid level, high liquid level sensor sends signal, multistage centrifugal pump startup, and discharge condensed water, when condensed water reaches low liquid level, low liquid level sensor sends the signal of telecommunication, and centrifugal multistage pump multiple centrifugal pump stops, and so circulates.The shortcoming that above-mentioned this scheme exists is; because whole air channel and collecting tank are all in great negative pressure state, the centrifugal multistage pump multiple centrifugal pump of row's condensed water often can suck air, gently then can cause centrifugal multistage pump multiple centrifugal pump cisco unity malfunction; impact is produced, and can make the damage of centrifugal multistage pump multiple centrifugal pump time serious.
Utility model content
The purpose of this utility model is to provide a kind of tobacco extraction liquid evaporation concentrator condensate drain, the condensed water produced when this tapping equipment energy safety, the effectively work of exudate evaporation concentrator.
For achieving the above object, the utility model adopts following scheme: tobacco extraction liquid evaporation concentrator condensate drain, there is collecting tank, high liquid level sensor and low liquid level sensor, it also has the blowdown vessel of a sealing, the level height of blowdown vessel is lower than collecting tank, and be communicated with fluid-through tube by breather pipe between the two, blowdown vessel upper, lower end is connected to an air inlet pipe and discharging tube respectively, high liquid level sensor, low liquid level sensor is loaded on collecting tank and blowdown vessel respectively, at breather pipe, fluid-through tube, air inlet pipe and discharging tube are equipped with a controllable valve respectively, high liquid level sensor and low liquid level sensor connect with the receiving terminal of a valve control device, each controllable valve connects with a control end of valve control device respectively.
From such scheme, collecting tank is connected with the bottom, air channel before inspissator blower fan, under the state that controllable valve on breather pipe and fluid-through tube is opened, controllable valve on air inlet pipe and discharging tube is closed, the condensed water entering collecting tank can enter into blowdown vessel, when the liquid level in collecting tank reaches the position of high liquid level sensor, valve control device makes the controllable valve on the closedown of the controllable valve on breather pipe and fluid-through tube, air inlet pipe and discharging tube open, air can be entered, by drain line drains condensed water by air inlet pipe; When the liquid level in collecting tank reaches the position of low liquid level sensor, valve control device makes that the controllable valve on breather pipe and fluid-through tube is opened, controllable valve on air inlet pipe and discharging tube is closed, and moves in circles according to this, realizes the discharge of condensed water in air channel.
The utility model is rational in infrastructure, use safety, reliable, it changes traditional mode with pump discharge condensed water, reduces use and maintenance cost, extends service life.
