Abstract
The utility model relates to a device, in particular to a multichannel vapor ejector which can utilize the residual heat with low-parameter to heat water or other medium. The multichannel vapor ejector comprises a water inlet chamber and a water outlet chamber, which is characterized in that the water inlet chamber is connected with a gas inlet chamber; a plurality of spray pipes are arranged on a connection wall between the water inlet chamber and the gas inlet chamber; a mixed flow pipe is arranged on the underside of the gas inlet chamber corresponding to the outlet of the spray pipe, and the end part of which is communicated with the water outlet chamber. The utility model has the advantages of more reasonable structure, increasing the contact superficial area between vapor and water, mixing the vapor and water and transferring the momentum completely, and increasing the ejection coefficient; the utility model shortens the total length of the device greatly, can be installed and used conveniently and saves the space; the utility model also has the advantages of small pressure loss and electricity conservation, and can be widely applied to the energy recovery of the low-parameter vapor.
Description
(1) technical field
The utility model relates to the equipment that a kind of waste heat that utilizes low parameter steam adds hot water or other media, is a kind of multichannel steam injector specifically, belongs to energy-conserving product.
(2) background technology
If the waste heat in the low parameter steam does not utilize, will cause the waste of a large amount of energy.In today of energy growing tension, people are at the waste heat of considering how can to make full use of in the low parameter steam.Because the pressure of low parameter steam is low, specific volume is big, volume specific heat is little, if the face of employing formula heat exchanger, the coefficient of heat transfer is very low in the heat exchanging process, requires heat exchange area very big, make that the volume of heat exchanger is very big, the consumption metal material is many, the cost height, and low-voltage vacuum state condensate water discharge difficulty is big; If adopt hybrid absorption plant, spray process need hydraulic pressure, waste water pump electric energy, and structure is also huger.
(3) summary of the invention
The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes a kind of multichannel steam injector, recycles low-pressure steam, can recycle heat energy wherein, again can using water wisely, and reduce the volume of equipment.
The utility model purpose is realized by following technical scheme: this multichannel steam injector includes intake chamber and water-supplying chamber, it is characterized in that intake chamber connects air chamber, a plurality of water spray pipes are installed on the connecting wall between intake chamber and the air chamber, export corresponding position with water spray pipe on the bottom surface of air chamber mixed flow tube is installed, mixed flow tube is terminal to be communicated with water-supplying chamber.
Water spray pipe mixed flow tube corresponding with it formed a passage, several can be installed to hundreds of water spray pipes and mixed flow tube in air chamber, forms several to hundreds of passages.Because passage is many, the contact surface that has increased steam and water is long-pending, and it is more abundant that Momentum Transfer is mixed with carbonated drink, thereby improved mass ratio of induced-to-inducing air, i.e. vapour, water quality ratio.Because mixed flow tube length is directly proportional with nozzle diameter, multi-channel structure can shorten the equipment total length greatly than single channel structure, and is easy to install and use, conserve space.
The water spray pipe end is provided with nozzle, and the caliber size of nozzle can guarantee that the outlet design current velocity is at the 10-100 meter per second.Because steam and water enter the direction basically identical of mixed flow tube simultaneously, can reduce the pressure loss, save the electric energy of voltage supply water pump.
Mixed flow tube is connected to form by the diffuser at introduction segment, middle part straight tube and the rear portion of front portion, introduction segment is for shrinking pyramidal structure, tapering is 2 °-20 °, inlet end has the arc flange, diffuser is the expansion taper, tapering is 2 °-20 °, and the length of mixed flow tube is 4-20 times of middle part straight tube diameter, and the flow area of middle part straight tube is 1-5 a times of exit area of nozzle.The effect of the anterior introduction segment of mixed flow tube is to import steam, and the effect of rear portion diffuser is can change speed into the pressure energy.
The utility model operation principle is the water of elevated pressures, enters intake chamber by the import of intake chamber, quickens to inject mixed flow tube through nozzle, produce extremely low pressure, low-pressure steam enters air chamber through the import of air chamber, under the effect of utmost point low-pressure behind the nozzle, is inhaled into mixed flow tube, vapour and water mix in mixed flow tube, steam is condensed, and vapour and water carry out momentum-exchange simultaneously, and finish pressure rise process at the diffuser of mixed flow tube, enter water-supplying chamber, discharge by outlet.
The utility model advantage is that structure is more reasonable, and the contact surface that has increased vapour and water is long-pending, and it is more abundant that Momentum Transfer is mixed with carbonated drink, improved mass ratio of induced-to-inducing air; Shortened the equipment total length greatly, easy to install and use, conserve space; The pressure loss is little, saves energy.
