Abstract

The utility model relates to a circular seam ejector that is used in the technological fields, such as drainage, boiler, heating ventilation and so on. The spout of a normal ejector is round; the ejected medium is column-shaped; thus the efficiency is low. In the circular seam ejector, the ejecting mixed flow tube with two ends shaped like a bell mouth is provided with a spout with an ejecting tongue; the spout is shaped like a circular seam; media can be ejected from the ejecting tongue and the gap between nozzles so as to form a shape like a pipe; thus the circular seam ejector improves the speed and increases the contact surface with the material to be pumped and dissolved. When being used as an air exploder and an oxygen-increasing pump, the circular seam ejector can generate oxygen with tinier particle size and improve the solubility of the oxygen. When being used as a desulfurization ejector, the circular seam ejector can generate tinier droplets of the ejected media, increase the contact surface with flue gas, and improve the desulfurization efficiency. When used as vacuum ejector pump, the circular seam ejector can eject more media to be pumped with the work media of equal quantity and equal parameters, and achieve a higher vacuum degree. Thus the circular seam ejector can save energy and improve the efficiency.

Description

The circumferential weld injector

Affiliated technical field

The utility model relates to the circumferential weld injector of a kind of energy suction medium, two alternate mixing, dissolving or chemically reactive.Be used for devices such as water-jet heat pump that the sudden and violent gas device of technical fields such as sewage disposal, HVAC, boiler, flue gas desulfurization alkali injector, plant condenser vacuumize and water body oxygenation.Especially can improve the circumferential weld injector that contacts area between medium injection speed, thinner injection granularity and bigger medium.

Background technology

The sudden and violent gas device of injecting type of sewage disposal at present is a gas water-jet pump, is classical De Laval noz(zle), and spray-hole is a circular hole.This device is to be used for water water heating and carbonated drink to heat the blender of usefulness.Because the medium of its ejection is cylindric, speed and surface area are all big inadequately, thereby particle is inadequately little, thus the molten spray of oxygen than little, the sewage degradation capability is low.Sudden and violent its particle of gas device of machinery partition type is thick especially; Used nozzle is used the nozzle in the air-conditioning trickle chamber always in flue gas desulfurization, and it is the water injector of tangential water inlet rotation back aperture water outlet, and the medium amount of its injection is few, speed is low, particle is also inadequately little, and desulfuration efficiency is low.Then institute's consumed power is too big at the sulfur method of aqueous slkali high speed rotation flue gas; The automatic aerator majority is to realize with machinery separation bubble or the sudden and violent gas head of sinter aperture.Its gas grain of this device is through thick especially, and molten spray is than littler; The water-jet heat pump that vacuumizes at plant condenser, be cylindric water column because of what spray equally, ejection medium speed and surface area are big inadequately, and the gas flow of being extracted out is also just insufficient, therefore make condenser vacuum not high enough, further improve thereby limited generating capacity.

Summary of the invention

Injector working media speed and surface area are big inadequately in order to overcome in above each field, grain through inadequately little, desulfuration efficiency is undesirable, power consumption is big, oxygenation is poor, the high inadequately deficiency of vacuum, the utility model provides a kind of circumferential weld injector, it is a kind of smooth olive shape spray tongue of adorning in circular spout, make spout become a circle circumferential weld, the spray tongue half in circumferential weld, half is outside circumferential weld.Ejection medium in a tubular form, thereby has improved working media speed and surface area from slit ejection between spray tongue and jet pipe.The injection mixed flow tube of overcoat is that to import and export all be tubaeform body.The import oviduct is lacked greatly, and the outlet oviduct is lacked and grown, and its neck is bigger than annular jet, is located at the annular jet front.Use field and requirement according to difference, each position can be designed to different physical dimensions.In some use field, injection mixed flow tube inwall is established spiral fin, to increase collision, contact, the mixing between medium.

The invention has the beneficial effects as follows: can improve the molten spray ratio of oxygen during as sudden and violent gas device or automatic aerator; When the flue gas desulfurization, can improve desulfuration efficiency, cost is low, equipment is little, energy-conservation; During the water-jet air pump that vacuumizes as plant condenser, under identical parameters equivalent working media, can increase rate of air sucked in required, thereby improve condenser vacuum, increase generated energy.

Below in conjunction with drawings and Examples the utility model is further specified.

Specific implementation method

In the embodiment shown in fig. 1, spray tongue (4) is contained in jet pipe (1) outlet, is fixed on jet pipe (1) outlet inwall with fin first (2), makes the spout of jet pipe (1) form a uniform circumferential weld.Two is bell-mouthed injection mixed flow tube (5) and is placed in outside the jet pipe (1), is taken out medium inlet side at quilt and fixes with fin second (3) and jet pipe (1) outer wall.Use the field and require each position can be designed to different geometrical size according to difference.

In another embodiment shown in Figure 2, spray tongue (4) is contained in jet pipe (1) outlet, is fixed on jet pipe (1) outlet inwall with fin first (2), makes the spout of jet pipe (1) form a uniform circumferential weld.Two is bell-mouthed injection mixed flow tube (5) and is placed in outside the jet pipe (1).Being taken out medium inlet side at quilt fixes with fin second (3) and jet pipe (1) outer wall.When being used in some technical field, for increasing collision, contact, the mixing between medium, its inwall is provided with spiral fin (6).Use field and requirement according to difference, each position is designed to different geometrical size.

Claims

1. a circumferential weld injector is characterized in that, at two being has a circular spout in the flaring injection mixed flow tube, in adorn a smooth olive shape spray tongue, make spout become a circumferential weld, the spray tongue half in circumferential weld, half is outside circumferential weld.
