Abstract
The utility model discloses a scale control evaporimeter for furfural waste water treatment, it goes out the middle chamber of one deck in the interval at the jar body middle part that has the waste water evaporimeter now again, shell and tube heat exchanger also divides into upper and lower two sections from middle, installs respectively in upper and lower two jar chambeies for upper and lower two sections, and tubulation two sections upper and lower all switches on with middle chamber to make the whole tube -type evaporator that is listed as fall into upper portion steam dewatering section, middle circulation layer and lower part siphon circulation evaporation zone, being equipped with the loop exit on middle chamber, being equipped with the circulation import lower jar of body lower part, loop exit and circulation import are with the useless recycling of water of pipeline switch -on implementation part, be equipped with thermal medium intercommunication mouth respectively in the bottom side in last jar chamber and the upside in lower jar chamber, two thermal medium intercommunication mouths are with pipeline switch -on, the lower jar chamber of thermal medium entering in jar chamber in the realization. The utility model discloses fundamentally has solved furfural waste water and in the scale deposit problem that heat exchange tube bottom liquid level delay caused, has prolonged the scavenging period, the problem of high liquid level vapour area water has also been solved.
Description
Technical field
The utility model relates to furfural mill sewage treatment equipment.
Background technology
At present, furfural waste-water vaporizer is the visual plant of furfural mill wastewater treatment.Traditional waste water vaporizer major constituents is, shell and tube heat exchanger is provided with in tank body, height 3 ~ the 4m of tubulation, aldehyde gas relief outlet is provided with at tank body top, bottom is provided with the wastewater outlet after process, side, bottom is provided with former waste liquid import, and be provided with the thermal medium inlet entering shell side on tank body top, tank body lower part is provided with thermal medium outlet; Furfural waste-water enters shell and tube heat exchanger tube side from former waste liquid import, high temperature thermal medium (saturated vapor or hot water) enters tank body shell side from thermal medium inlet, to the furfural waste-water heating of flowing in tube side, make a small amount of furfural evaporation in furfural waste-water, discharge from aldehyde gas relief outlet, discharge again after making waste water index reach national regulation value.The shortcoming of this equipment is, although the heat transfer tube length due to vaporizer reaches 3 ~ 4m height, but tube side liquid level can not be too high, liquid level too high furfural vapour meeting water entrainment, liquid level can only control at bottom 1/3 place, and this just causes easy fouling, not easy to clean bottom pipe end, have impact on the internal circulating load of furfural waste-water, cause wastewater treatment capacity influenced.
Summary of the invention
For the deficiency of traditional waste water vaporizer, a kind of antiscale vaporizer for furfural waste-water process of the utility model design.
A kind of antiscale vaporizer for furfural waste-water process, it is provided with shell and tube heat exchanger in tank body, aldehyde gas relief outlet is provided with at tank body top, bottom is provided with the wastewater outlet after process, side, bottom is provided with former waste liquid import, be provided with the thermal medium inlet entering shell side on tank body top, tank body lower part is provided with thermal medium outlet; It is characterized in that, described tank body middle part again between be separated out one deck intermediate cavity, tank body is divided into upper and lower two tank chambeies by intermediate cavity; Described shell and tube heat exchanger is also divided into upper and lower two sections from centre, upper and lower two sections are arranged in upper and lower two tank chambeies respectively, the tubulation of upper and lower two sections all with intermediate cavity conducting, make the furfural waste-water of tubulation hypomere enter tubulation epimere again after intermediate cavity, thus make whole shell and tube evaporator be divided into top steam dehydration section, intercycle layer and bottom siphon circulation evaporator section; Intermediate cavity is provided with loop exit, is provided with circulation import in lower tank bottom, the circulation realizing effluent part connected by loop exit and circulation import pipeline; Be respectively equipped with thermal medium connected entrance in the bottom side in upper tank chamber and the upside in lower tank chamber, two thermal medium connected entrance pipelines are connected, and in realization, the thermal medium in tank chamber enters lower tank chamber.
Utility model works principle and positively effect are that the furfural waste-water entered from former waste liquid import circulates in siphon circulation evaporator section limit heating edge, carries out eliminating water by steaming after entering top steam dehydration section.Furfural waste-water constantly circulates in the heat transfer tube of bottom, fundamentally solves furfural waste-water and is detained the scale problems caused in heat transfer tube bottoms level, extend scavenging period; Also solve high liquid level vapour band water problem, make furfural vapour water content little, thus increase the treatment capacity of waste water, treatment effect is good.According to statistics, this antiscale vaporizer year treatment capacity is the twice of former vaporizer treatment capacity.
