Abstract
The utility model relates to a rubbish landfill gas preprocess complete plant, which comprises a preprocess pipe, a pressure meter and a thermometer are arranged on the preprocess pipe, an inlet and an outlet of the preprocess pipe are in turn provided with a primary filter, a condenser, a gas-water separator and a fan, a flowmeter, a thermometer, a pressure meter and a gas analyzer are provided on the output pipe of the fan, an way of an output end of the fan after air cooling is connected to a gas electric generating set through a fine filter and a flame arrester, the other way of the output end of the fan is connected to a torch, according to the complete plant of the utility model, the quality of the landfill gas can be effectively improved, and the gas pressure can be stabilized, the requirement of the gas electric generating set to the gas can be satisfied, and the gas electric generating set can operate stably and reliably.
Description
Technical field
The utility model relates to a kind of rubbish landfill gas preliminary treatment complete set of equipments.
Background technology
The fuel that rubbish fills up the utilization of gas power plant is landfill gas, and landfill gas is a kind of fuel gas, i.e. our usually said biogas.The technological process of whole landfill gas power generation factory comprises that landfill gas is collected, landfill gas is handled, the generating of fuel gas generation unit and step-up transformer boost the back to grid transmission, and wherein to handle be a committed step to landfill gas.Landfill gas has usually near saturated relative humidity, in the conveying and processing procedure of gas, when gas temperature is lower than its dew point, will produce condensed water, under the effect of condensed water, if the corrosion composition in the gas not in addition the processing meeting operating generator is caused very big injury, the fine particle in the landfill gas also can cause wearing and tearing to the parts of generator in addition.
Summary of the invention
The purpose of this utility model is to provide a kind of rubbish landfill gas preliminary treatment complete set of equipments, and this equipment can effectively improve the quality of landfill gas and the air pressure of stabilizing gas, makes it satisfy the requirement of generator to combustion gas, guarantees that set steady moves reliably.
Of the present utility model being characterised in that: described preliminary treatment pipeline is provided with pressure gauge and thermometer, described preliminary treatment pipeline import and export is disposed with initial filtrator, condenser, moisture trap and blower fan, the output channel of described blower fan is provided with flowmeter, thermometer, pressure and takes into account gas analyzer, possesses CDM on-line monitoring function, the output one tunnel of described blower fan is connected to the fuel gas generation unit after by fine filter and spark arrester after air-cooled, and another road is connected to torch.
The rubbish landfill gas preliminary treatment complete set of equipments that the utility model provides is collected house steward with gas and directly is connected, swabbing action by blower fan is collected landfill gas in the pretreatment unit, stablize the gas that control can be met requirement by gas being carried out cool-down dehumidification, thickness filtration and outlet pressure again, this equipment is antiknock device, the safe class height; Each link of system comprises pipeline and all possesses automatic continuous drainage function; Cross when low when the preliminary treatment inlet pressure, system has the response of sound and light alarm even shutdown; When the winter temperature environment was lower than certain value, handpiece Water Chilling Units possessed automatic shutdown function; Cross when low when the preliminary treatment outlet temperature, air-cooled unit possesses automatic shutdown function; Control module adopts the engineering configuration software, acquisition process, storage data, supervisory control system running, friendly interface.

The specific embodiment
A kind of rubbish landfill gas preliminary treatment complete set of equipments, comprise the preliminary treatment pipeline, described preliminary treatment pipeline is provided with pressure gauge and thermometer, described preliminary treatment pipeline import and export is disposed with initial filtrator, condenser, moisture trap and blower fan, the output channel of described blower fan is provided with flowmeter, thermometer, pressure and takes into account gas analyzer, the output one tunnel of described blower fan is connected to the fuel gas generation unit after by fine filter and spark arrester after air-cooled, and another road is connected to torch.
Described condenser is a tubular heat exchanger, adopts cooling water as cooling media, and described moisture trap is the cyclone type gas and water separator, and described blower fan is a roots blower, and its drive motors adopts the frequency conversion fire-proof motor.
The course of work of the present utility model is as follows: landfill gas enters the person in charge and enters in the foam removal filter through stop valve, and bulky grain drop and immobilized particles in the source of the gas can be retained down, and discharges system by sewage draining exit; Gas enters in the condenser of lyophilization module again, and the gas after being cooled is through the gas-liquid separation filter branch liquid that condensation gets off of leaving away, and this module can also be removed the part high boiling substance in the source of the gas, as halogenated hydrocarbons, high-carbon hydrocarbon etc.; After the roots blower supercharging, through cooling heat exchanger the temperature of landfill gas is controlled at 30-40 degree centigrade again, then further removes the dust of diameter 〉=1 μ m through high efficiency particulate air filter, the gas that comes out at last is divided into two-way, one group is removed generating set through spark arrester, and another winding is to torch.
