Abstract

The utility model relates to a hot tube heat conductive inner heating chemical reaction tank, which is composed of a tank body and a tank cover. The utility model is characterized in that a heating chamber is positioned under the tank body, the inner wall of the tank body is uniformly distributed with heat pipes, the evaporation section of the heat pipes passes through the tank bottom and a heat insulation section and is positioned in the heating chamber, when the utility model is operated, material in the tank is directly heated by the heat pipes. The utility model solves the problems that when the tank body of an ordinary outer heating reaction tank is acutely heated, an anticorrosive lining layer can crack and fall off and can be damaged, and the service life is short. The utility model has the advantages that the heat loss can be reduced, and the thermal efficiency can be improved. The utility model is suitable for various tank class appliances which needs heating such as reaction tanks, evaporating tanks, storage tanks, etc.

Description

A kind of heat pipe for thermal conductivity internal heating type chemical reaction jar

A kind of heat pipe for thermal conductivity internal heating type chemical reaction jar belongs to chemical industry retort kind equipment.

Existing chemical industry generally is made up of tank body, cover, charging aperture, agitating device, heating clamber with retort, and its heating clamber generally is made up of the chuck between the double-level-metal plate that constitutes tank body.Retort allows steam, conduction oil or other heating agents with uniform temperature pass through from heating clamber in the time of need heating, metallic plate and corrosion protective lining layer the material conduct to jar in of its heat by the retort inner tank wall makes the material heating, and this mode of heating is called external heating type.This mode of heating is because heating agent at first contacts with tank body, and heat is conducted by tank body material in jar then, thereby a jar interior material heats up slower; In addition, because tank body sharply is heated, attached to the corrosion protective lining layer on the inner tank wall because of causing corrosion protective lining slabbing line, come off or damage with the coefficient of expansion of tank body material is inconsistent, thereby reduce the service life of retort, in addition because external heating type retort heating location is outer, thereby its heat loss is bigger, and the thermal efficiency is lower.

Order of the present utility model is to provide a kind of and can directly heats material in the jar in retort, reduces heat loss, improves the thermal efficiency, the internal heating type retort that the while can keep the corrosion protective lining layer of jar inwall to be difficult for crackle, to come off and to damage again.

The purpose of this utility model is to realize like this.

A kind of heat pipe for thermal conductivity internal heating type chemical reaction jar, by tank body, cover, charge door on the cover, the discharging opening of tank base is formed, it is characterized in that: the tank body below is provided with heating clamber, and heating clamber is provided with heating agent import and heating agent outlet, is provided with heat pipe around inner tank wall, the evaporator section of heat pipe bottom passes tank base, is positioned at the heating clamber of tank body below.

The said heat pipe for thermal conductivity internal heating type of the utility model chemical reaction jar, the outer surface that it is characterized in that heat pipe can cover anti-corrosion material, and can between tank base and heating clamber, isolation section be set, said isolation section is to separate and keep a segment distance with metal or its material at heating clamber and retort bottom, the space of isolation section can be heat insulation with vacuum or air, also can fill other heat-barrier materials, for example asbestos, rock wool etc.

The said heat pipe for thermal conductivity internal heating type of the utility model chemical reaction jar, being particularly useful for graphite is the retort of lining material, the outer surface of said heat pipe also can cover the graphite overcoat.

The said heat pipe internal heating type of the utility model chemical reaction jar, owing to be directly to contact heating with a jar interior material with heat pipe, and heat pipe is the high-efficiency heat conduction element of generally acknowledging, thereby firing rate is fast, owing to be that a jar interior material is heated earlier, tank body is owing to jar intensification of interior material heats up, thereby tank body is heated slowly and evenly in addition, avoid because of tank body sharply heat up the anticorrosion lining of inner tank wall that causes crackle, come off and damage, prolong the service life of jar.This in addition mode of heating also can reduce heat loss, improves the thermal efficiency.

The utility model is described in further detail below in conjunction with accompanying drawing.

Accompanying drawing 1 is a heat pipe for thermal conductivity formula internal-heating chemical retort schematic diagram.

Cover 7 is arranged at the top of reacting tank body 5, cover 7 is provided with charging aperture 6, be provided with discharge opening 12 in the middle of the bottom of tank body 5, be provided with agitating device 9 in the tank body, heating clamber 11 is structure and be positioned at the below of retort in the form of a ring, heating clamber 11 is provided with heating agent import 10 and heating agent outlet 1, and the periphery of inner wall of tank body 5 is provided with heat pipe 3 equably, and the quantity of heat pipe 3 and length can also should be determined according to demand for heat.The evaporator section of heat pipe 3 inserts in the heating clamber 11 by jar end and isolation section 2, the inwall of tank body 5 and cover 7 is provided with corrosion protective lining layer 8, the outer surface of heat pipe 3 is coated with anticorrosive coat 4, corrosion protective lining layer 8 and corrosion protective lining 4 can be graphite materials, enamel etc., wherein excellent with the graphite material performance, its heat-conducting effect is also relatively good, a segment distance is kept apart and kept to heating clamber 11 with tank body 5, make the heats in the heating clamber 11 can not be from tank body 5 outside at the bottom of the direct heating tank, be that available being evacuated also can be heat insulation with air in the space of isolation section 2, also can insert asbestos, heat-barrier materials such as rock wool are heat insulation.

When retort is worked, add the industrial chemicals that needs processing by charging aperture 6 earlier in jar, steam, conduction oil or other heating agents enter heating clamber 11 by heating agent import 10, the evaporator section that is positioned at the heat pipe 3 of the heating clamber 11 back heat that is heated conducts to the industrial chemicals of tank body 5 heating tanks rapidly, meanwhile, agitating device in jar begins to rotate stirring, make the industrial chemicals thermally equivalent, heating agent outlet 1 after the heat release cooling is discharged, so continuously as required material in the jar is heated, till reaching requirement.

The utility model promptly is applicable to the retort of band corrosion protective lining layer, also be applicable to the retort of not being with the corrosion protective lining layer, also be applicable to simultaneously other for example equipment that need heat its built-in substance such as evaporator, storage tank, the outer surface of heat pipe 3 and tank body 5 inwalls etc. can cover anticorrosive coat in addition, also can not cover anticorrosive coat, cover the kind of anticorrosive coat and whether cover anticorrosive coat and should determine according to the purposes of retort and the medium of processing.
