Abstract
The utility model relates to a circulating pump type vertical horizontal volume type heat exchanger. The utility model is characterized in that one side of a tank body is provided with a complete enclosed type water pump which has small power, low lift and high flow; the inlet of a heating medium pipeline is provided with a temperature automatic adjustment valve; an electrical automatic control box controls the size of opening the water pump according to the variation of the output temperature of the water of the tank; a cooling medium water input pipe and a cooling medium output pipe are provided with manual valves and bypassing pollution discharge valves; the side of the tank body is provided with the electrical automatic control box. The utility model is capable of heating the water in the tank in the forced convection mode, eliminates the stagnation region of the cold water of the bottom of the tank, enhances the heat exchange coefficient six to seven times, increases the heat exchanger efficiency, decreases the temperature of the condensation water, dispenses with a steam trap and is suitable for a hot water supply system.
Description
The utility model belongs to the heat-exchange apparatus that general heat-exchange apparatus, particularly heat exchange medium directly do not contact.
At present, in the domestic hot-water supply system of industry and civil buildings, the upright volumetric heat exchanger that crouches obtains more application, but have the following disadvantages: the water storage of heat-exchanging tube bundle bottom often is the cold water stagnant area in the heat exchanger water storing tank, water temperature is lower, do not satisfy the temperature requirement that design is supplied water, make the interior water storage volume of the upright volumetric heat exchanger tank body that crouches can not get utilizing to greatest extent; The upright volumetric heat exchanger that crouches, before hot-water supply, often earlier being full of cold water in the jar, close the hot and cold water water inlet pipe and water outlet pipe then, open heating agent water inlet pipe valve again, the jar inner cold water is heated, because the tank body inner cold water does not circulate substantially, so be enclosed free convection heating, its coefficient of heat transfer is lower.
The purpose of this utility model is, in the upright volumetric heat exchanger system that crouches, set up a small-power, low lift, high flow capacity, Totally-enclosed-type water pump, and the electric automatic control device of wearing at random, carry out the operation of automatically controlled water pump, so that the outer water velocity of heat-exchanging tube bundle strengthens in the tank body, thereby improve heat exchanger effectiveness.
The upright volumetric heat exchanger that crouches of circulating pump type of the present utility model, form by tank body, heat-exchanging tube bundle, refrigerant water inlet pipe and water outlet pipe, heating agent water inlet pipe and water outlet pipe, it is characterized in that, side at tank body is provided with a small-power, low lift, high flow capacity, Totally-enclosed-type water pump, be provided with automatic temperature control valve in the import of heating agent pipeline, according to the variation of leaving water temperature in the jar, by the size of electric automatic control case control water pump unlatching; On the refrigerant water inlet pipe and water outlet pipe, be provided with hand-operated valve, on the refrigerant inlet pipeline, establish bypass blowoff valve and blow-off pipe; At the other electric automatic control case that is provided with of tank body.
The upright operation principle that crouches volumetric heat exchanger of circulating pump type of the present utility model is: cold water enters the bottom that pipe 8 enters tank body by cold water, after heat-exchanging tube bundle 2 is heated, flows out from tank body top, delivers to the user.The heating agent (steam or high-temperature-hot-water) that boiler produces flows through automatic temperature control valve 5 and enters in the heat-exchanging tube bundle through hot-water line 6, by a jar inner cold water cool, after the exchange heat, by condensation return pipt 7, flow back to boiler again, after in boiler, being heated, be sent again, so repeatedly circulation.Before hot water supply user, in the tank body 1 all is cold water, heating agent enters in the heat-exchanging tube bundle jar inner cold water is heated, owing to be heated the specified temp that cold water temperature is lower than the designing user requirement in initial jar, start by electric automatic control case instruction water circulating pump 4 this moment, water pump is by suction hose 11, upper water in the cucurbitula through water pump and pressure pipe 12, pumps into the bottom of tank body again, make waterbornely in the tank body to circulate down, through heat-exchanging tube bundle acceleration heat convection.After water temperature in the jar arrives particular design user temperature, deliver to the user by hot-water line 10, simultaneously by the stall of electric automatic control case instruction water pump.When user's water consumption is bigger, when its leaving water temperature was lower than designing user requirement specified temp, the electric automatic control case instructed water pump to put into operation again, carries out so repeatedly.
The upright volumetric heat exchanger that crouches of circulating pump type of the present utility model has the following advantages: owing to set up water circulating pump, can make jar interior water become the forced convertion heating, can make its convection transfer rate improve 5～10 times; The upright volumetric heat exchanger water storage volume that crouches is utilized, can eliminates a jar inner bottom part cold water stagnant area; Can make the temperature that reaches designing requirement of the even water temperature of jar interior water storage; Because the flowing velocity of water has improved heat exchanger effectiveness in having quickened jar, make heating agent pass through heat-exchanging tube bundle after temperature drop strengthen, condensate temperature is greatly reduced, generally can reduce to below 85 ℃, thereby can save steam trap, simplified hot water supply system.Be applicable to hot water supply system.
Below in conjunction with drawings and Examples, the utility model is done into description.
Fig. 1 is the organigram of the upright volumetric heat exchanger that crouches of circulating pump type
As seen from the figure, the upright volumetric heat exchanger that crouches of circulating pump type, form by tank body, heat-exchanging tube bundle, refrigerant water inlet pipe and water outlet pipe, heating agent water inlet pipe and water outlet pipe, it is characterized in that, side at tank body 1 is provided with a small-power, low lift, high flow capacity, Totally-enclosed-type water pump 4, be provided with automatic temperature control valve 5 in the import of heating agent pipeline, according to the variation of leaving water temperature in the jar, by the size of electric automatic control case 3 control water pumps unlatchings; On refrigerant water inlet pipe and water outlet pipe 8, be provided with hand-operated valve, on the refrigerant inlet pipeline, establish bypass blowoff valve 13 and blow-off pipe 9; At the other electric automatic control case 3 that is provided with of tank body.
