Abstract

The utility model discloses a vapor-water mixing heater, which comprises a barrel and a vapor inlet connected to the sidewall of the barrel. A water spraying pipe is arranged in the barrel. Both a spraying-in section and a spraying-out section of the water spraying pipe are tapered pipes. The smaller-diameter of the tapered pipe of the spraying-in section is connected with the smaller-diameter end of the tapered pipe of the spraying-out section through a cylindrical short pipe. Vapor spray orifices are formed in the sidewall of the tapered pipe of the spraying-out section. The axis of each vapor spray orifice forms an included angle alpha of 30 to 60 degrees with the axis of the water spraying pipe. A baffle plate is also arranged at the vapor inlet. A filter hole is formed in the baffle plate. When the vapor-water mixing heater works, heated water under certain pressure is sprayed into the heater through the Rafael pipe-shaped water spraying pipe, the inclined vapor spray orifices are formed in the sidewall of the spraying-out section, and vapor is sprayed into water through the inclined vapor spray orifices, and is fully mixed with the water when flowing at high speed, so that a contact area is enlarged, and a heat exchange load in heating is effectively improved; and the vapor-water mixing heater has the advantages of simple structure, high heat exchange efficiency, low noise and the like, and can be used for supplying domestic hot water and production hot water.

Description

Steam-water injection

Technical field

The utility model belongs to the heat-exchange apparatus technical field, relates in particular to a kind of carbonated drink Hybrid Heating equipment that utilizes vapour directly to add hot water.

Background technology

Steam-water injection adopts steam and is heated the mode that water directly contacts and carries out heat exchange; Its thermal efficiency is high; Usually the structure of this type heater is that water flows in jet pipe; Vapour gets in the water through the tube wall aperture outside jet pipe, and vapour mixes in heater with water, and the water that will flow through in the jet pipe constantly adds thermal output heat supply water user.Though but the higher noise of this type heater thermal efficiency is big.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of noise little, the steam-water injection that the thermal efficiency is high.

The utility model for realizing the technical scheme that above-mentioned purpose adopted is:

A kind of steam-water injection; Comprise cylindrical shell and be connected in the steam inlet on the cylinder lateral wall; Be provided with water spray pipe in the cylindrical shell; It is characterized in that: the section of spraying into of said water spray pipe is conical pipe with the ejection section, and the section of spraying into conical pipe is connected with the column short tube with the less end of diameter of ejection section conical pipe, and the sidewall of ejection section conical pipe is provided with steam fumarole.

Flow in order to be beneficial to steam, reduce flow path resistance, cut down the consumption of energy and running noises, the angle of the axis of the described steam fumarole of the utility model and the axis of water spray pipe is 30 °～60 °.

As the preferred version of said structure, the angle of the axis of described steam fumarole and the axis of water spray pipe is 45 °.

In order to reduce the impulsive force of steam to sparge pipe, reduce rebound phenomenon, low vibration of battle array and water attack noise, place, the described steam inlet of the utility model also is provided with baffle plate, and baffle plate is provided with filtering holes.

Be that the water that is heated with certain pressure draws your tubular water spray pipe of valve to spray into through being during the work of the steam-water injection of the utility model; On the sidewall of ejection section, be provided with oblique steam fumarole; The steam of certain pressure sprays into the water from oblique steam fumarole, and the two fully mixes in flow at high speed, and carbonated drink was mixed the contact area increase when steam sprayed into; Exchanged heat when having improved heating is effectively loaded, and makes the instant water that sprays and come obtain heating, the acute liter of temperature; Steam is by disperseing tiny steam fumarole to spray in the water when mixing owing to carbonated drink simultaneously; Can not form steam and water bursting, thereby suppress jet noise effectively, carbonated drink mixing is in a kind of low noise state carry out; Control the flow velocity at each mobile position and can accomplish that there are the high efficiency of heating surface noiselessness, shockproof and direct the mixing; Vapour locking is little, and kinetic energy consumption is lower, is convenient to starting.The utlity model has advantages such as simple in structure, that heat exchange efficiency is high, noise is little, can be used for living, producing supply with hot water.
