Abstract
The utility model relates to the technical field of heat exchange devices, in particular to a heat exchanger with double liquid outlets. The heat exchanger comprises a shell, a pipe, a cooling liquid inlet and the cooling liquid outlets. The heat exchanger is characterized in that the double liquid outlets are composed of a bottom cooling liquid outlet, a top cooling liquid auxiliary outlet, the top of the shell is provided with a cooling liquid inlet and a cooling liquid auxiliary outlet, the bottom of the shell is provided with the cooling liquid outlet, the pipe is arranged in the shell, and the pipe is spiral. The cooling liquid auxiliary outlet is formed in the top of the heat exchanger, the effect of cooperation of the cooling liquid inlet, the cooling liquid auxiliary outlet and the cooling liquid outlet is achieved, and once the cooling liquid outlet is blocked, cooling liquid can flows out from the cooling liquid auxiliary outlet to form a cooling liquid circulation. Unexpected accidents due to the fact that the heat exchanger is suddenly blocked are eliminated, potential safety hazards are effectively reduced and relieved, and moreover common swage or desalted water is used as the cooling liquid, operation cost is saved to the maximum, and the effects of energy conservation and emission reduction are achieved.
Description
[technical field]
The utility model relates to the heat-exchange apparatus technical field, specifically a kind of pair of liquid outlet 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 is greatly all smooth common steel tubes of inside and outside surface, easily exist heat exchange efficiency lower, the problems such as easy fouling and obstruction, and in the situation that the cooling fluid upper entering and lower leaving is as only having the liquid outlet in bottom, in case the impure serious formation incrustation of cooling fluid finally can cause heat exchanger to stop up, fouling this moment stopping state at first occurs in the lower liquid outlet of heat exchanger bottom, in case the lower liquid outlet obstruction can cause cooling fluid to circulate and heat exchanger was thoroughly lost efficacy.
Consider and utilize cooling fluid to import and export quantity and putting position can address the above problem, therefore occurred cooling fluid is imported and exported the scheme that quantity and putting position are transformed.
[summary of the invention]
The purpose of this utility model, improve in existing heat exchanger tube pass and liquid outlet quantity and positional structure basis, a kind of burst accident that can prevent effectively that shell wall from blocking, fouling brings equipment is provided, effectively reduces and alleviate two liquid outlet heat exchangers of safety in production hidden danger.
For achieving the above object, design a kind of pair of liquid outlet heat exchanger, comprise shell side, tube side, cooling liquid inlet and cooling liquid outlet, it is characterized in that two liquid outlets of described pair of liquid outlet heat exchanger are comprised of the cooling liquid outlet of bottom, the cooling fluid auxiliary liquid outlet at top, described shell side top is provided with cooling liquid inlet and cooling fluid auxiliary liquid outlet, described shell side bottom is provided with cooling liquid outlet, is provided with tube side in the shell side, and described tube side in the shape of a spiral.
In the heat exchanger of the present utility model, adopt two up and down liquid outlets, set up specifically a cooling fluid auxiliary liquid outlet at the heat exchanger top, form the effect that cooling liquid inlet, cooling fluid auxiliary liquid outlet and cooling liquid outlet three work in coordination with, cooling fluid can be flowed out by the cooling fluid auxiliary liquid outlet at top and form liquid circulation when especially in a single day stopping up appearred in the bottom liquid outlet, can get rid of heat exchanger and stop up suddenly the burst accident that brings equipment, effectively reduce and alleviate safety in production hidden danger;
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 ".
[description of drawings]
Fig. 1 is the structural representation of the two liquid outlet heat exchangers of the utility model;
1. cooling liquid inlets, 2. shell sides, 3. tube sides, 4. cooling liquid outlets, 5. cooling fluid auxiliary liquid outlets among the figure.
[specific embodiment]
For making the purpose of this utility model, principle and product configurations more cheer and bright, now be further elaborated in conjunction with the drawings and the specific embodiments, believe for a person skilled in the art and can realize, the realization of technical solutions of the utility model specifies with the following example:
Embodiment one
Tangential direction heat exchanger in the present embodiment as shown in Figure 1, critical piece has: by the cylindrical shell side 2 that metal material is made, described shell side 2 contains cavity, and fixedly tube side 3 be used for to be installed; The tube side 3 of being made by metal pipe material bends to helical form with described tube side 3 and forms the cylindrical structural of hollow out;
Tube side 3 is installed in the cavity of shell side 2, offer a cooling liquid inlet 1 and a cooling fluid auxiliary liquid outlet 5 at shell side 2 tops, cooling liquid inlet 1 is used for injecting cooling fluid or connects the coolant duct outlet, and cooling fluid auxiliary liquid outlet 5 mainly is when stopping up appears in outlet at bottom, form interim liquid circulation, in shell side 2 bottoms a cooling liquid outlet 4 is set, this cooling liquid outlet 4 is used for the discharge of cooling fluid or connects coolant duct entering the interruption-forming circular flow.
When above-mentioned heat exchanger used under normal circumstances, because there is liquid self gravitation phenomenon in heat exchanger inside, the flow direction of cooling fluid was upper entering and lower leaving, formed eddy flow along helical form tube side 3, and cooling fluid forms circulation by cooling liquid outlet 4 outflows of heat exchanger bottom; Under abnormal condition, when especially stopping up appears in the cooling liquid outlet 4 of bottom, cooling fluid can be flowed out by cooling fluid auxiliary liquid outlet 5 and form liquid circulation, gets rid of heat exchanger and stops up suddenly the burst accident that brings equipment, effectively reduces and alleviate safety in production hidden danger.
