A temperature sensitive element and a control circuit can be used for automatically regulating the valve opening degree of an executor and controlling the steam flow so as to achieve the purpose of producing hot water based on a preset temperature (20 DEG-150 DEG C). The device has the functions of automatic steam cutting, water cutting, protection and warning on the occasion of power failure. The utility model has the advantages of small volume, high thermal efficiency, controllable heating temperature difference, energy saving, safety, etc., and is suitable for the systems of dining rooms, bath rooms and hot water heating as well as the heating of the fluid with low viscosity and non-corrosiveness during the industrial processes.
Description
The utility model belongs to a kind of steam and hot water device.
As everyone knows, use the most general steam and hot water device, adopt the wall-type heat exchange mode usually, promptly hot and cold two kinds of fluids are separated by a fixed wall, and heat reaches the another side by a side of solid.This heat exchange mode, heat exchange efficiency is low, the heat exchange device is long-pending big.For example, for the garden bobbin shell heat exchanger that building heating is used, need take one more than ten square metre room.
Since the seventies, static mixing formula steam water heater comes into one's own.This class hybrid heater is built-in with some stationary elements, when cold and hot two kinds of fluids pass through, is just cut apart respectively, and changes the flow direction, thereby reach the purpose of abundant mixed heat transfer.At present, the static mixing heater of existing 30 number of different types comes into operation.Wherein, the jet tube steam-water injection is a kind of novel steam-water injection (referring to Fig. 1) that domestic in recent years design is gone into operation, it is mainly by the shell that has three flanges (1), jet pipe (2), square (3), filler (4), drain plug (5) is formed, steam is connected with the flange of shell by corresponding pipeline respectively with water at low temperature to be sent into, mixed heat transfer in device is exported high-temperature water then under steam and hydraulic pressure.Advantages such as this heat exchanger has the heat exchange efficiency height, the heating temperature difference is big, and volume is little, operate steadily.But also have the following disadvantages: the first, because this device itself does not possess regulatory function, can not control steam and flow of inlet water size, so can not control vapour, the mixed temperature of water.Second, from energy-conservation angle, the jet tube steam-water injection in actual use, required quantity of steam differs greatly under the different heating temperature difference, for example, and when the heating temperature difference when being 20 ℃ and 80 ℃, its required quantity of steam differs 5 times, when only needing the hot water of lower temperature, still, then caused the waste of the energy by specified quantity of steam steam supply.The 3rd, when power failure caused that water pump is shut down the nothing water inlet, vapour source continued steam supply, then caused overheated easily and steam scald accident.The 4th, this device does not possess complete property, has caused inconvenient part with installing and using for the supporting of user.
The purpose of this utility model is to provide a kind of comprehensive, energy automatic temperature-control, energy autostop when former when anything crops up, safe and reliable, energy-conservation steam and hot water device.
The utility model is a heater block with the jet tube steam-water injection, comprise that simultaneously steam pipework, water at low temperature pipeline, high-temperature water pipeline and water temperature detect, regulation control part, adopt frame and connector that above-mentioned pipeline and parts are formed incorporate integral body simultaneously.
Steam and hot water device of the present utility model has been done rational selection on water temperature control scheme.In order to guarantee jet tube steam heater operate as normal, be provided with steam, Inlet and outlet water pressure detecting indicating device.Be provided with temperature-sensing element (device) in the high-temperature water outlet, the temperature information that temperature-sensing element (device) detects by control loop, changes the size of steam flow, realizes the control of water temperature.Add the hot water temperature and can set (20~150 ℃) as required, when actual heating-up temperature is higher or lower than set-point temperature, controller is integral differential (PID) mode in proportion, regulate the driving electric operator and turn down or open big steam flow automatically, make and add hot water and reach design temperature, thereby realize supplying with an amount of steam on demand, avoided the waste of steam energy.
The utility model is provided with multi-function electromagnetic valve on steam pipework and water at low temperature pipeline, when power outage takes place, can cut off steam automatically, in order to avoid overtemperature and steam scald accident occur.On control mode, connect feedwater during startup earlier, steam is connected in the back, has guaranteed safe in utilization.
The utility model steam and hot water device takes to connect in the same side the mode of steam pipework, water at low temperature pipeline, high-temperature water pipeline, utilizes bend pipe structure to carry out the temperature expansion amount and compensates naturally, reduces internal stress, and makes compact conformation, volume little.For example, per hour produce the device of 10 tons of hot water, floor space is less than one square metre, and is more much smaller than other heater with same capabilities.
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Accompanying drawing 1 is a jet tube steam-water injection structural representation.
Accompanying drawing 2 is a steam and hot water apparatus structure schematic diagram.
Accompanying drawing 3 is the instrument and the control circuit principle of steam and hot water device.
Accompanying drawing 5 is applied to circulatory system schematic diagram for the steam and hot water device.
