Description
Technical field
The utility model relates to a kind of equipment that utilizes the gas pressure difference generating, particularly a kind of equipment that utilizes poisonous and harmful and flammable explosive gas differential pressure power generation.
Background technique
Rock gas, coal-seam gas, ethene or the like flammable explosive gas is sent in the user procedures at the gas station, often there is the pressure situation that do not match, be generally 10mp-2mp such as rock gas gas station suction pressure, and the user uses kitchen range to only require 2000p pressure, so the output gas pressure generally also will be adjusted by valve opening in rock gas gas station, make the output gaseous-pressure reach standard-required, but like this, in vain energy dissipation that gaseous-pressure has has been fallen.At present, also lack a kind of power generating equipment of utilizing gas differential pressure.Also possesses safety anti-explosive electricity generate function device simultaneously
Chemicals liquid chlorine and liquefied ammonia and hydrogen sulfide gas or the like are that human body and environment are produced serious danger harmful matter, pressure is up to 15-30mp before the user uses, the user uses equipment requirement pressure well below this pressure, for the method for using the reduction valve aperture to adjust delivery pressure reaches user.At present, also lack a kind of generating that utilizes toxic and harmful pressure reduction.Also possess simultaneously not have and leak explosion-proof safe power generation functional device
The model utility content
The purpose of this utility model is to provide a kind of devices inflammable and explosive and the many pressure difference generatings of toxic and harmful that utilize.
The purpose of this utility model is achieved through the following channels: a kind of gas differential pressure generating device, sealing cylinder casing wall two ends are provided with suction port and relief opening, two gas inlet and outlets are communicated with admission line and outlet pipe respectively, install in the cylinder and have or not the wind dispelling machine, the rotor shaft connection generator on the blower fan.
As further improvement, no wind dispelling machine has two kinds of structural types, and a kind of is that fan blade axially is installed on the rotor shaft; Another kind of fan blade radially is installed on the rotor shaft.Fan blade and rotor shaft are axially to install, and the suction port on the cylinder casing wall and the position of relief opening correspond respectively to the both sides of blade place covering of the fan; Fan blade and rotor shaft are what radially install, the suction port on the cylinder casing wall and the position of relief opening respectively in the rear and front end of blade place covering of the fan.
In addition, described generator is an explosion-proof power generator.Described rotor shaft is installed on the seal arrangement that is provided with on the cylinder casing wall.Described fan blade length slightly is shorter than the cylinder block internal diameter.
The utility model gas differential pressure generating device utilizes the draught head generating when having replaced reduction valve, differential pressure power generation machine toggle speed is fast, and control easily, simple in structure, purchase and user cost low, the efficient height does not use fuel, both turned waste into wealth, energy saving does not produce exhaust emission pollution simultaneously yet.
Simultaneously, it also has lot of advantages:
1. economic environmental protection.As a kind of utilization of new energy resources device, it does not have the water power investment huge, floods the good farmland, and the resettlement of the residents builds dam, changes the shortcoming of ecotope, and it is low but to have water power operating cost, the characteristics of generation environment-friendly.There do not have thermoelectricity to pollute big operation personnel to be many, and the high shortcoming of cost but has short advantage of construction of fire and electricity cycle.There is not the investment of wind-powered electricity generation big, the technical requirements height, local remote, the power cost height but has the environmental protection characteristic of wind-powered electricity generation.
2. the energy replenishes.Rock gas one annual consumption variation characteristics are that high spring and summer of autumn and winter is low, and one day consumption variation characteristic is that daytime is high to 10 of evenings, and all the other times are few.This is roughly to be that consistent (itself is consistent, and resident's daily life is worked, and the time of rest is exactly electricity consumption and with gas peak and low ebb time with residential electricity consumption variation characteristics.Water consumption also is like this.) multiple electricity when rock gas pressure reduction generating can be accomplished the electric power peak, generate electricity less during the electric power low ebb and power usage synchronous, the natural peak load stations of can doing uses.
3. remarkable benefit.Since rock gas gas station all build in the city or near, so the generating of rock gas pressure reduction is the close user in the city also, construction cost and electric transmission line are seldom both saved investment business and are economized on resources like this, transfering natural gas from the west to the east Shanghai Duan Yinian gas consumption is 8,000,000,000 cubes, calculate with side's gas 2 degree that can generate electricity, just can obtain 16,000,000,000 degree, the utility model can obtain extraordinary economic benefit and social benefit as implementing.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model critical piece structure enlarged diagram;
Fig. 3 is the another kind of embodiment's of the utility model a structural representation;
Fig. 4 is the another kind of embodiment's of the utility model a critical piece structure enlarged diagram.
Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the gas differential pressure generating device, sealing cylinder 8 casing wall two ends are provided with suction port 10 and relief opening 9, two gas inlet and outlets are communicated with the admission line and the outlet pipe of caisson respectively, install in the cylinder 8 and have or not the wind dispelling machine, the rotor shaft 6 connection generators 1 on the blower fan.
No wind dispelling machine has two kinds of structural types:
A kind of is that fan blade 7 axially is installed on the rotor shaft 6, and as shown in Figure 1 and Figure 2, the suction port 10 on cylinder 8 casing walls and the position of relief opening 9 correspond respectively to the both sides of blade 7 place covering of the fans;
Another kind is that fan blade 7 radially is installed on the rotor shaft 6, and as shown in Figure 3, Figure 4, the suction port 10 on cylinder 8 casing walls and the position of relief opening 9 be the rear and front end of blade 7 respectively.
Because the gas that this device contacted is inflammable and explosive and toxic and harmful, to the safety requirement height, the matching requirements safety anti-explosive does not have leakage effect, and described generator 1 is an explosion-proof power generator, and 4 is novel respond well seal arrangement.
