Abstract

The invention provides a pipeline fluid fast heater which relates to an energy-saving electric heating technology. The invention aims at the shortages of the existing electric heating pipe typed heating mode of large heat loss and large energy consumption. The invention discloses a part consisting of a shell, an inlet and an outlet; wherein, the shell is sequentially sleeved with a middle sleeve and a hollow heating pipe along the transverse direction; the hollow heating pipe comprises an external heat conduction pipe, and an external insulation layer, a cirque electric heating part, an internal insulation layer and an internal heat conduction pipe arranged from exterior to interior; the middle sleeve and the hollow heating pipe are inserted between an upper electrode seat and a lower electrode seat; the shell, the upper electrode seat and the lower electrode seat are inserted between an upper fixed fitting and a lower fixed fitting. The invention has the advantages of high heat energy utilization ratio, small heat capability, small power loss, small volume, fast heating, saving energy, safety and reliability and long service life.

Description

A kind of pipeline type liquid quick heater

Technical field

The present invention relates to a kind of pipeline fluid be carried out the electric heater of rapid heating, particularly can in pipeline flows, carry out the electric heater of rapid heating water, oil, chemical liquid or air.

Background technique

The heater that existing convection cell heats extensively adopts electric heating tube as heater element, exists the working life that electric leakage hidden danger, easily fouling, localized heat speed comparatively fast influence electric device by its heating arrangement of forming.In order to solve its deficiency, No. 8620666 patent disclosures include the electric water heater that control circuit, fluid control, aqueduct, heating unit are formed, heating unit is to make extraction electrode around upper conductor on the high temperature insulation tube outer surface, coat the air-dry back of electric heating film liquid again and become electric heating film, add insulating protective layer, water advances height from the heat-resistant insulation tube low side and brings out, and this Guan Duozhi is used in combination; Also have the CN1802043A specification to disclose the liquid heating element that a kind of water power is isolated, it comprises that at least one plating is made up of electrothermal semiconductor rete and the electric heating tube matrix that has an extraction electrode this element, wherein the outer surface of electric heating tube matrix and electrothermal semiconductor rete disposes reflector, outer surface of outer cover has isolation layer, and this element heating element can use use also capable of being combined separately.It conducts heat and to cover diabatic process by heating unit, tube wall, water in preceding solution, and the thermal efficiency is low, and under equal conditions its thermal process speed is slow, and energy consumption is big, and especially thermal capacitance causes power can not satisfy fast hot requirements of saving energy greatly greatly, and is still undesirable.

Summary of the invention

At the prior art deficiency, the present invention proposes a kind of heat energy utilization rate height, thermal capacitance is little, consumed power is little, volume is little, speed is hot, a kind of pipeline type liquid quick heater of energy-conservation, safety, long service life.

The technical solution adopted for the present invention to solve the technical problems is: it includes shell, inlet, outlet, in the shell in laterally sheathed successively spacer pipe and by outer heat-transfer pipe, the hollow heating tube that external insulation layer, annular electro heating piece, inner insulating layer, interior heat-transfer pipe are formed.Wherein between outer casing inner wall and the middle spacer pipe, form the cavity of flow of fluid between middle spacer pipe and the hollow heating tube, middle spacer pipe bottom is provided with the hole of backflowing; Middle spacer pipe and the hollow heating tube of forming by outer heat-transfer pipe, external insulation layer, annular electro heating piece, inner insulating layer and interior heat-transfer pipe, socket is between upper and lower electrode tip holder, and the upper electrode seat is provided with flow concentration hole; Shell, upper electrode seat, lower electrode holder socket are at last accessory admittedly with down admittedly between the accessory, going up admittedly, accessory has inlet, admittedly accessory has outlet down, flowing medium in the electric heater pipeline after the combination successively behind the cavity of cavity that inlet, shell and cavity, the hole of backflowing, middle spacer pipe and outer heat-transfer pipe that middle spacer pipe forms form, flow concentration hole, interior heat-transfer pipe from the outlet discharge, finish once inside and outside the hollow heating tube the two-sided fluid medium repeatedly flush type heating process of making a circulation.

Good effect of the present invention is: heat energy utilization rate height, thermal capacitance is little, consumed power is little, volume is little, speed is hot, energy-conservation, safe and reliable, long service life.
