Abstract
The utility model relates to chemical equipment and provides a gas mixing device which has a simple structure, avoids a flow dead angle of mixed gas and is easy to operate. The gas mixing device disclosed by utility model comprises a barrel, the upper end of the barrel is communicated with a truncated cone barrel cover, a blocking plate is fixed at the lower end of the barrel, a first air inlet pipe penetrates through the blocking plate and enters the barrel, a base plate is encapsulated at an orifice of the first air inlet pipe in the barrel, a spacing board is arranged between the inner side of the barrel and the outer surface of the first air inlet pipe, the side wall of the barrel between the spacing board and the blocking plate is communicated with the second air inlet pipe, a plurality of gas uniform distribution holes are arranged on the base plate, the side wall of the first air inlet pipe between the base plate and the spacing board, the spacing board and surface of the barrel cover, and inner diameters of the gas uniform distribution holes are gradually increased from the middle point of the board thickness to the two sides. The gas mixing device disclosed by the utility model can effectively avoid a flow dead angle of mixed air and achieves the aim of fully mixing.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, particularly relates to a kind of gas mixer.
Background technology
Mostly the gas mixer of chemical industry use at present is process route length, internal diameter and the bigger equipment of volume, and the even program that gas mixes is unsatisfactory, and flow blind angle is arranged; There is gas bias current phenomenon in various degree; Cause dischargeable capacity to reduce, the process duct line length, occupation area of equipment is big; The admixture of gas composition does not often reach designing requirement, influences product quality.
The utility model content
The utility model provide a kind of simple in structure, avoid gas mixed flow dead angle, gas mixer easy and simple to handle.
The utility model gas mixer; Comprise cylindrical shell, said cylindrical shell upper end is communicated with the Rotary-table cover, and the lower end is closure plate fixedly; First air inlet pipe is passed closure plate and is got into barrel; The mouth of pipe of first air inlet pipe is packaged with base plate in the said cylindrical shell, between the inboard and said first air inlet pipe outer surface of said cylindrical shell space bar is set, and said space bar is communicated with second air inlet pipe with cylinder lateral wall between the closure plate; On the said base plate, between base plate and the space bar on the first air inlet pipe sidewall, offer the even gas distribution hole on the space bar and on the cover surface, said even gas distribution hole internal diameter slave plate wall thickness mid point increases to the two sides gradually.
The utility model gas mixer fluid resistance of having set up the increase even gas distribution hole that internal diameter increases gradually had a mind to from the center to both sides compared with prior art; Reach suitable with circumferential resistance force; Force fluid suitable, avoided the generation of flow blind angle at the different parts flow of flow area.
Below in conjunction with accompanying drawing the utility model gas mixer is described further.
Description of drawings
Fig. 1 is the utility model gas mixer cutaway view;
Fig. 2 is the utility model gas mixer vertical view.
The specific embodiment
As depicted in figs. 1 and 2; The utility model gas mixer comprises cylindrical shell 1, and cylindrical shell 1 upper end is communicated with Rotary-table cover 2, and the lower end is closure plate 3 fixedly; First air inlet pipe 4 is passed closure plate 3 and is got into cylindrical shell 1 inside; The mouth of pipe of first air inlet pipe 4 is packaged with base plate 9 in the cylindrical shell 1, between inboard and first air inlet pipe, 4 outer surfaces of cylindrical shell 1 space bar 6 is set, and space bar 6 is communicated with second air inlet pipe 5 with cylindrical shell 1 sidewall between the closure plate 3; On the base plate 9, between base plate 9 and the space bar 6 on first air inlet pipe, 4 sidewalls, on the space bar 6 and cover 2 uper side surfaces offer even gas distribution hole 8, even gas distribution hole 8 internal diameter slave plate wall thickness mid points increase to the wooden partition two sides gradually.
A kind of in use gas of the utility model gas mixer gets into from second air inlet pipe 5; In the process of advancing, run into the resistance of space bar 6, can only get into Rotary-table cover 2 through the even gas distribution hole on the space bar 68, another kind of gas is through first air inlet pipe 4; Receiving the terminal base plate 9 of body stops and can only get into Rotary-table covers 2 from base plate 9 and even gas distribution hole 8 on the sidewall; 8 internal diameter slave plate wall thickness centers, even gas distribution hole increase to both sides gradually, have a mind to increase fluid resistance, reach suitable with circumferential resistance force; Force fluid suitable, avoided the generation of flow blind angle at the different parts flow of flow area.After two kinds of gases evenly distribute, carry out effectively evenly mixing, overflow from the even gas distribution hole 8 of Rotary-table cover 2 side surfaces, thereby realized the purpose that process route weak point, small investment, gas mix in Rotary-table cover 2 spaces.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
