Abstract

The utility model provides a variable-temperature anti-corrosion separating heat pipe exchanger. The separating heat pipe exchanger is divided into a regulating stage and a basic stage; electronic valves are mounted on the riser of the regulating stage, while no electronic valve is mounted on the riser of the basic stage; one part of the electronic valves mounted on the riser of the regulating stage of the separating heat pipe exchanger can be selected to accurately regulate the flow, while the other electronic valves are common electronic valves only with on and off states. A temperature sensor is mounted at a fluid inlet or outlet where the temperature is required to be controlled; the on and off states or the opening of the electronic valves can be regulated according to the temperature signal of the temperature sensor.

Description

A kind of temp. controllable anticorrosion separate type heat pipe exchanger

Technical field

The utility model relates to a kind of temp. controllable anticorrosion separate type heat pipe exchanger.

Background technology

At present, known heat exchange of heat pipe heats the evaporator section of heat pipe by hot fluid, hydraulic fluid in tube core is subject to thermal evaporation, and takes away heat, and steam flows to the condensation segment of heat pipe from central passage, condense into liquid, emit Topography cold fluid, under the effect of capillary force and gravity, liquid backflow is to evaporator section simultaneously, so just complete a closed circulation, thereby a large amount of heats has been passed to cold fluid from hot fluid.But, the heat transfer effect of common heat exchange of heat pipe can not regulate in real time artificially in heat transfer process, this has just caused under different operating modes, cause fluid outlet temperature to change because heat exchange amount is different, can not meet user for the controlled demand of fluid outlet temperature, simultaneously when with fluid heat transfers such as flue gases, along with the variation of operating mode, in heat transfer process, may cause cold end corrosion by opposite heat tube heat exchanger, have a strong impact on the service life of heat exchange of heat pipe.

Summary of the invention

Can not realize the artificial heat exchange amount that regulates in real time in order to overcome general heat pipe heat exchanger, cause fluid outlet temperature not in the deficiency of perfect condition, the utility model provides the Novel separated type heat exchange of heat pipe of working medium flow in a kind of adjustable heat pipe, this separate type heat pipe exchanger can be by regulating the flow resistance of heat pipe inner fluid to realize the adjusting of working medium flow, and then realize the adjusting of heat exchange amount, control fluid inlet and outlet temperature, and can prevent cold end corrosion.

The technical scheme in the invention for solving the technical problem is: separate type heat pipe exchanger is divided into governing stage and base level, on governing stage tedge, electronic valve is housed, on base level tedge, there is no electronic valve, the electronic valve of installing at the tedge place of separate type heat pipe exchanger governing stage, need the selected part electronic valve can accurate flow adjustment according to user, another part electronic valve be only to have the ordinary electronic valve of opening and close two states.At the fluid inlet or the exit mounting temperature sensor that require to control temperature, regulate on off state or the aperture of electronic valve according to the temperature signal of temperature sensor.In the time that temperature sensor is arranged on fluid outlet, temperature signal is during lower than (or higher than) setting value, adjusting can accurate flow adjustment electronic valve, make its aperture increase (or reducing), open (or closing) ordinary electronic valve in closed (standard-sized sheet) state when its standard-sized sheet (closure), and make fine adjustment electronic valve close (standard-sized sheet), when temperature signal still repeats aforesaid operations process higher than when setting value; In the time that temperature sensor is arranged on fluid intake end, temperature signal just regulates electronic valve that can accurate flow adjustment during higher than (or lower than) setting value, make its aperture increase (or reducing), open (or closing) ordinary electronic valve in closed (or standard-sized sheet) state when its standard-sized sheet (or closing), and make fine adjustment electronic valve close (or opening), when temperature signal repeats aforesaid operations process during still higher than (or lower than) setting value.

The beneficial effects of the utility model are, by regulating the heat exchange amount of separate type heat pipe exchanger, can manual control fluid inlet and outlet temperature, and reach the object that obtains ideal temperature fluid or prevent heat exchange of heat pipe cold end corrosion.
