Abstract
The utility model relates to the technical field of heat exchange equipment, in particular to a conical heat exchanger. The conical heat exchanger comprises a shell pass, a tube pass, a cooling liquid inlet and a cooling liquid outlet. The conical heat exchanger is characterized in that the shell pass is conical or the upper portion of the shell pass is cylindrical, the lower portion of the shell pass is conical, the tube pass is arranged inside the shell pass, the sectional area of the top of the conical part of the shell pass is larger than the sectional area of the bottom part of the conical part of the shell pass, the cooling liquid inlet is formed in the top of the shell pass, the cooling liquid outlet is formed in the bottom of the shell pass, the tube pass is spiral, and the spiral diameter of the top of the tube pass is larger than the spiral diameter of the bottom of the tube pass. According to the conical heat exchanger, the conical big-end-up structures are adopted by both the shell pass and the tube pass, the function of gravity and the function of centrifugal force are used, flowing speed of fluid gradually becomes faster, intensity of pressure is decreased, impurities in the cooling liquid are effectively taken away, the outer wall of the tube pass and the inner wall of the shell pass are washed and brushed to enable the heat exchanger not to be prone to forming scaling to be blocked, heat exchange effect is improved, ordinary sewage or demineralized water is used as the cooling liquid, operating cost is saved to the greatest extent, and the energy-saving and consumption-reducing effect is achieved.
Description
[technical field]
The utility model relates to the heat-exchange apparatus technical field, specifically a kind of conical heat exchanger.
[background technology]
The cold exchange device of using in the industry technological processes such as the present oil of China, chemical industry is shell-and-tube heat exchanger in a large number, this class has the advantages such as simple in structure, lightweight, that cost is low, be applicable to the stringent process conditions such as various high temperature, high pressure, complex dielectrics, in the numerous kinds heat transmission equipment, occupy an leading position.But existing shell-and-tube tubular heat exchanger, its heat exchanger tube mostly are greatly all smooth common steel tubes of inside and outside surface, easily exist heat exchange efficiency lower, easily the problems such as fouling and obstruction.
The problems referred to above that exist in order to solve the shell-and-tube tubular heat exchanger, consider utilize flow through the time itself deposit tool impulsive force can remove the heat exchanger tube inwall and stop up, therefore the scheme that the heat exchanging tube shape is transformed has appearred, such as the disclosed a kind of cone-shaped telescopic tube for shell-and-tube heat exchanger of domestic patent CN202074869U, its heat exchange principle is to utilize the special construction of this inner-walls of duct, utilize specifically the conical tube of continuous intussusception, 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, utilize the conical tube bigger diameter end to consist of the crest of this heat exchanger inner tube, miner diameter end consists of the trough of this heat exchanger inner tube.Therefore when flow through the time because the ripple on the inner-walls of duct, thereby form strong turbulent flow and strong disturbance, thus the heat transfer coefficient of raising heat exchanger tube.But the fluctuation of this heat exchanger tube inner wall shape only can change the flow through path of fluid on traffic direction, but can not change in fact the speed of flow warp, therefore still has defective.
[summary of the invention]
The purpose of this utility model is improved at the architecture basics that has heat exchanger shell pass and tube side now, provides a kind of and can prevent effectively that shell wall from blocking, the conical heat exchanger of fouling.
For achieving the above object, design a kind of conical heat exchanger, comprise shell side, tube side, cooling liquid inlet and cooling liquid outlet, it is characterized in that described shell side is conical, be provided with tube side in the shell side, shell side top cross-sectional area is greater than the bottom transverse sectional area, the shell side top is provided with cooling liquid inlet, shell side bottom is provided with cooling liquid outlet, described tube side in the shape of a spiral, described tube side top screw diameter is greater than the bottom screw diameter.
A kind of conical 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, the shell side bottom is conical, is provided with tube side in the shell side, and shell side lower cone shape top cross-sectional area is greater than the conical lower section cross-sectional area, shell side top cylinder-shaped top is provided with cooling liquid inlet, shell side lower cone shape bottom is provided with cooling liquid outlet, described tube side in the shape of a spiral, described tube side top screw diameter is greater than the bottom screw diameter.
Cooling fluid in the above-mentioned heat exchanger is upper entering and lower leaving.
In the heat exchanger of the present utility model, shell side and tube side all adopt tepee structure, up big and down small taper shape specifically, when cooling fluid enters the middle flow process that end opening flows out from suitable for reading, the tube side of the shell side inner conical of need to flowing through, owing to being subject to the effect of gravity and centrifugal force, the flow velocity of coolant fluid can be more and more fast, the liquid outlet flow velocity strengthens, pressure reduces not only can effectively take away in the cooling fluid impurity to reduce sediment, flow velocity strengthens the effect of washing away tube side outer wall and shell side inwall of playing, advantage is that heat exchanger is difficult for forming fouling and is difficult to stop up, and conical top is because heat exchange area increases, and heat transfer effect is improved;
By using this new type heat exchanger, can use general sewage or demineralized water as cooling fluid, and needn't cause that because water quality is not good the fouling of heat exchangers blockage problem removes to be replaced with fresh water (domestic use of water) as cooling fluid or increase the fund input that other improve water treatment schemes (improving quality problem), need not change original state of arts and under the prerequisite that guarantees the equipment operational reliability maximum saving equipment operating cost so that the input-output ratio optimum becomes a reality---namely reach performance and the result of a kind of " saving energy and reduce the cost ".
