Description
Technical field
The utility model relates to a kind of anti-return natural gas dryer.
Background technology
Sweet natural gas siccative is used for, in industrial production, being main equipment, generally includes two drying towers arranged side by side, well heater, recirculation blower, water cooler, and the complex construction compositions such as strainer, are unfavorable for carrying with.
For the problems referred to above, publication number is that the patent document of CN201959708U discloses a kind of Portable natural-gas dryer, its technical scheme is: form primarily of box base, inlet suction port, O-ring seal, orifice plate, box body, lid, up-hole plate, central intake pipe, siccative and exhaust joint, box body is a cylindrical vessel, box body has the end, be connected with a lid in the screw top of box body, between lid and box body, have a gasket; It is characterized in that: have a cylindrical box base at box body inner bottom part, an air chamber caved in is had in box base upper end, centre hole is had bottom air chamber, the top of centre hole is connected with a central intake pipe, centre hole lower end and horizontal air inlet port UNICOM, inlet suction port is fixed on the air inlet port of box base through the outer wall of box body; Bottom the air chamber of box base, have venting hole, exhaust joint is fixed on the venting hole of box base through the outer wall of box body; There is a circular orifice plate at the top of box base, between box base and orifice plate, have O-ring seal; Central intake pipe is through orifice plate centre hole; Siccative is filled with on the top of orifice plate; A circular up-hole plate is had on the top of siccative; Central intake pipe is through up-hole plate centre hole.
In the technical scheme of above-mentioned patent, because needs airflow pipeline does not arrange filtration unit, easily occur that orifice plate blocks and the situation causing Sweet natural gas to reflux.
Utility model content
The utility model is intended to provide a kind of anti-return natural gas dryer, to solve owing to not arranging filtration unit in prior art, easily occurs that orifice plate blocks and the problem causing Sweet natural gas to reflux.
Anti-return natural gas dryer in this programme, base case is: comprise cylindrical shell, and described cylindrical shell top is provided with inlet mouth, is provided with air outlet in the middle part of described cylindrical shell upper wall, described cylindrical shell top is provided with safety valve, screen plate is provided with successively from the top down, orifice plate one, orifice plate two in described cylindrical shell, siccative is provided with between described orifice plate one and orifice plate two, also comprise thrust-augmenting nozzle, connection air outlet, described thrust-augmenting nozzle one end, the described thrust-augmenting nozzle the other end is between orifice plate two and cylindrical shell bottom surface.
Principle of work and beneficial effect: time dry, Sweet natural gas is passed into by inlet mouth, air-flow is after filter plates between access aperture plate one and orifice plate two, after drying agent drying, thrust-augmenting nozzle is entered by one end of the thrust-augmenting nozzle between orifice plate two and cylindrical shell bottom surface, then discharge through air outlet along thrust-augmenting nozzle, complete drying and follow bad.Unlike the prior art, owing to being provided with screen plate in cylindrical shell, and screen plate is above siccative, so gas first filters through filter plate plate, the particulate matter blocking orifice plate avoided in gas causes backflow.In addition, owing to being provided with safety valve on cylindrical shell top, when gas endoparticle is more, when the filter pore of screen plate is blocked, the air pressure in screen plate and barrel space increases, and safety valve is opened, avoids the backflow of Sweet natural gas.In sum, this programme makes device there will not be the situation of gas backstreaming by the combination of screen plate and safety valve.
Scheme 2, as the improvement to base case, the lower end of described cylindrical shell is provided with sealing cover.Advantage is, convenient taking-up siccative and screen plate are cleared up.
Scheme 3, as the improvement to scheme 2, the contact surface of described sealing cover and cylindrical shell is provided with gasket.Advantage is, prevents the junction of sealing cover and cylindrical shell from leaking gas.
Scheme 4, as the improvement to scheme 3, described sealing cover diameter is greater than barrel diameter.Advantage is, conveniently takes off sealing cover.
Scheme 5, as the improvement to base case, described inlet mouth is arranged on the sidewall on cylindrical shell top.Advantage is, avoiding inlet mouth and air outlet to mix up affects drying operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model anti-return natural gas dryer embodiment 1.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: sealing cover 10, gasket 11, cylindrical shell 20, thrust-augmenting nozzle 30, orifice plate 2 40, siccative 50, orifice plate 1, screen plate 70, safety valve 80, air outlet 90, inlet mouth 100.
Embodiment 1
As shown in Figure 1, anti-return natural gas dryer, scheme is: comprise cylindrical shell 20, cylindrical shell 20 top is provided with inlet mouth 100, be provided with air outlet 90 in the middle part of cylindrical shell 20 upper wall, cylindrical shell 20 top is provided with safety valve 80, is provided with screen plate 70 successively from the top down in cylindrical shell 20, orifice plate 1, orifice plate 2 40, is provided with siccative 50 between orifice plate 1 and orifice plate 2 40, also comprise thrust-augmenting nozzle 30, connection air outlet, thrust-augmenting nozzle 30 one end 90, thrust-augmenting nozzle 30 the other end is between orifice plate 2 40 and cylindrical shell 20 bottom surface.
In addition, in the present embodiment, the lower end of cylindrical shell 20 is provided with sealing cover 10.Advantage is, convenient taking-up siccative 50 and screen plate 70 are cleared up.Sealing cover 10 is provided with gasket 11 with the contact surface of cylindrical shell 20.Advantage is, prevents sealing cover 10 from leaking gas with the junction of cylindrical shell 20.Sealing cover 10 diameter is greater than cylindrical shell 20 diameter.Advantage is, conveniently takes off sealing cover 10.Inlet mouth 100 is arranged on the sidewall on cylindrical shell 20 top.Advantage is, avoiding inlet mouth 100 and air outlet 90 to mix up affects drying operation.
Time dry, Sweet natural gas is passed into by inlet mouth 100, air-flow through filter plate 70 filter after between access aperture plate 1 and orifice plate 2 40, after drying agent 50 drying, thrust-augmenting nozzle 30 is entered by one end of the thrust-augmenting nozzle 30 between orifice plate 2 40 and cylindrical shell 20 bottom surface, then discharge through air outlet 90 along water conservancy diversion 30 pipe, complete drying and follow bad.Unlike the prior art, owing to being provided with screen plate 70 in cylindrical shell 20, and screen plate 70 is above siccative 50, so gas first filters through filter plate plate 70, the particulate matter blocking orifice plate avoided in gas causes backflow.In addition, owing to being provided with safety valve 80 on cylindrical shell 20 top, when gas endoparticle is more, when the filter pore of screen plate 70 is blocked, screen plate 70 increases with the air pressure in cylindrical shell 20 space, safety valve 80 is opened, avoids the backflow of Sweet natural gas.
