Description
[technical field]
The present invention relates to heat-exchange apparatus technical field, specifically a kind of rotational flow heat exchanger.
[background technology]
The cold exchange device applied in the industry technological processes such as the current oil of China, chemical industry is shell-and-tube heat exchanger in a large number, this kind of have the advantages such as structure is simple, lightweight, cost is low, be applicable to the stringent process conditions such as various high temperature, high pressure, complex dielectrics, occupy an leading position in numerous kinds heat transmission equipment.But, existing shell-and-tube tubular heat exchanger, its heat exchanger tube is mostly all smooth common steel tube in inside and outside surface, easily there is heat exchange efficiency lower, the problems such as easy fouling and blocking, and when cooling fluid upper entering and lower leaving as only having one, bottom liquid outlet, once the impure serious formation incrustation of cooling fluid finally can cause heat exchanger to block, now first fouling and clogging situation occurs in the lower liquid outlet of exchanger base, and lower liquid outlet is once blocking can cause cooling fluid to circulate and to make heat exchanger thoroughly lose efficacy.
In order to solve the easy fouling of shell-and-tube tubular heat exchanger and blockage problem, consider that the impulsive force of itself depositing tool when utilizing fluid to flow through can remove the blocking of heat exchanger tube inwall, therefore occurred that heat exchanging tube shape carries out the scheme transformed, a kind of cone-shaped telescopic tube for shell-and-tube heat exchanger disclosed in domestic patent CN202074869U, its heat exchange principle is the special construction utilizing this inner-walls of duct, utilize the conical tube of continuous intussusception specifically, the miner diameter end of a upper pitch circle Taper Pipe is plugged in the bigger diameter end of next conical tube, so move in circles, conical tube bigger diameter end is utilized to form the crest of this inner tube of heat exchanger, miner diameter end forms the trough of this inner tube of heat exchanger.Therefore when fluid flows through, due to the ripple on inner-walls of duct, thus form great turbulence level and strong disturbance, thus improve the heat transfer coefficient of heat exchanger tube.But the fluctuation of this heat exchanger tube inner wall shape, only alter can flow through path on traffic direction, but can not the speed that flows through of alter in fact, therefore still there is defect; Consider and utilize cooling fluid import and export quantity and putting position to solve the problem, therefore occurred the scheme that cooling fluid import and export quantity and putting position are transformed.
[summary of the invention]
Object of the present invention, the basis of existing heat exchanger shell pass, tube side structure and liquid outlet quantity and positional structure is improved, shell wall from blocking, fouling to provide one effectively to prevent, and effectively can prevent the burst accident that shell wall blocks, fouling brings equipment, effectively reduce and alleviate the rotational flow heat exchanger of safety in production hidden danger.
For achieving the above object, design a kind of rotational flow heat exchanger, comprise shell side, cooling fluid, tube side, cooling liquid inlet and cooling liquid outlet, it is characterized in that described shell side conically, tube side is provided with in shell side, shell side top cross-sectional area is greater than bottom transverse sectional area, side, shell side top is provided with cooling liquid inlet, shell side top is provided with cooling fluid pilot outlet, cooling liquid outlet is provided with bottom shell side, in the shape of a spiral, described tube side top cross-sectional diameter is greater than bottom transverse diameter of section to described tube side.
A kind of rotational flow heat exchanger, comprise shell side, tube side, cooling liquid inlet and cooling liquid outlet, it is characterized in that described shell side top is cylindrical, shell side bottom is conical, tube side is provided with in shell side, shell side lower cone shape top cross-sectional area is greater than conical lower section cross-sectional area, the side, top of shell side Upper cylindrical shape is provided with cooling liquid inlet, cooling liquid outlet is provided with bottom shell side lower cone shape, the top of shell side Upper cylindrical shape is provided with cooling fluid pilot outlet, described tube side in the shape of a spiral, tube side top cross-sectional diameter in shell side lower cone shape is greater than bottom transverse diameter of section.
Described cooling liquid inlet is all or part of tangentially enters shell side.
Described cooling fluid is upper entering and lower leaving.
Rotational flow heat exchanger of the present invention is a kind of new type heat exchanger invented according to the easy fouling and clogging of heat exchanger, advantage not easily forms fouling, not easily block, improve cooling effect, effective guarantee equipment long-term operation, reduce and repair cleaning intensity and alleviate safety in production hidden danger, will produce huge economic benefit once put into production use, it structurally has following advantage:
(1) shell side and tube side all adopt tepee structure, taper shape up big and down small specifically, when cooling fluid is from the middle flow process entering end opening and flow out suitable for reading, need the tube side flowing through shell side inner conical, owing to being subject to the effect of gravity and centrifugal force, the flow velocity of coolant fluid can be more and more fast, liquid outlet flow velocity strengthens, pressure reduces not only effectively to take away in cooling fluid impurity to reduce sediment, flow velocity strengthens and plays the effect of washing away tube side outer wall and shell side inwall, advantage is that heat exchanger not easily forms fouling and is difficult to blocking, conical top increases due to heat exchange area, heat transfer effect is improved,
(2) described inlet is improved to all or part ofly tangentially enters shell side, effect is the eddy flow effectively forming cooling fluid, because cooling fluid is the eddy flow entering along shell side inwall tangential direction and formed, conical shell side can make again eddy flow produce necessarily downward active force, while shell side inwall dirt layer and tube side outer wall dirt layer are washed away, the eddy flow of downward active force makes the impurity in cooling fluid better discharge from lower liquid outlet, its advantage is that heat exchanger not easily forms fouling, not easily block, cooling effect improves;
(3) design of upper and lower two liquid outlets composition, realize under abnormal condition, namely when blocking appears in bottom liquid outlet, cooling fluid can be flowed out by top liquid outlet and form liquid circulation, heat exchanger can be got rid of and block suddenly the burst accident bringing equipment, effectively reduce and alleviate safety in production hidden danger.
By using this new type heat exchanger, general sewage or demineralized water can be used as cooling fluid, and fouling of heat exchangers blockage problem need not be caused to go to be replaced with fresh water (domestic use of water) as cooling fluid or the fund input increasing other improvement water disposal plan (improving quality problem) because water quality is not good, original state of arts need not be changed and under the prerequisite ensureing equipment operational reliability maximum saving equipment operating cost, input-output ratio optimum is become a reality---namely reach performance and the result of a kind of " saving energy and reduce the cost ".
