Abstract

The utility model belongs to the technical field of low-concentration gas electricity generation and particularly relates to a gas concentration monitoring device on a gas inlet pipeline of a gas generator set. The gas concentration monitoring device is characterized in that gas concentration testing instruments and electric control valves are connected to the gas inlet pipeline of the gas generator set in series; an industrial personal computer is in wireless connection with the gas concentration testing instruments and the electric control valves. By monitoring the gas concentration value, economical running of the gas generator set can be ensured, and idling of the gas generator set can be prevented.

Description

Gas density supervisory device on a kind of gas electricity unit admission line
Technical field
The utility model belongs to low-concentration gas power generation technical field, specifically, is the gas density supervisory device on a kind of gas electricity unit admission line.
Background technique
In recent years; progressively maturation along with low-concentration gas power generation technology; progressively be applied to each large colliery, the whole nation; so both can effectively solve coal mine gas explosion, improve Safety of Coal Mine Production condition; be conducive to again increase clear energy sources supply, reduce greenhouse gas emission, reach the multiple target of protection life, reserved resource, protection of the environment.
Yet, because the reasons such as coal production operation, gas bearing diminish gas density, cause like this gas electricity unit of low-concentration gas power generation factory when gas density is lower, there is uneconomical operation problem, when serious, even there is the phenomenon of idle running.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the gas density supervisory device on a kind of gas electricity unit admission line that can guarantee gas electricity unit high-efficiency and economic operation is provided.
The utility model solves the technological scheme that its technical problem adopts: the gas density supervisory device on a kind of gas electricity unit admission line, comprise gas density test instrument 1, electric control valve 2 and process control machine 4, it is characterized in that, gas density test instrument 1 and electric control valve 2 are connected on the admission line of gas electricity unit 3, between process control machine 4 and gas density test instrument 1 and electric control valve 2, be wireless connections, wherein gas density testing instrument 1 is mainly used in testing gas density and concentration value is transferred to process control machine 4, process control machine 4 opens or closes by making electric control valve 2 make after the signal analysis of gas density test instrument 1 action of controlling conduit entrance accordingly.
When gas concentration is during lower than the economic value of current unit operation, first close the pipeline of concentration value minimum, through after a period of time, while measure finding gas concentration still lower than the economic value of current unit operation, close again remaining pipes, until the gas concentration of other units is higher than the economic value of current unit operation.
The beneficial effects of the utility model are, by monitoring gas concentration, not only can guarantee the running of gas electricity Unit Economic, can also prevent the idle running of gas electricity unit.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the gas density supervisory device on a kind of gas electricity unit of the utility model admission line.
In figure: 1, gas density test instrument, 2, electric control valve, 3, gas electricity unit, 4, process control machine.
Embodiment
Referring to Fig. 1, gas density supervisory device on a kind of gas electricity unit admission line the utility model proposes, comprise gas density test instrument 1, electric control valve 2 and process control machine 4, it is characterized in that, gas density test instrument 1 and electric control valve 2 are connected on the admission line of gas electricity unit 3, between process control machine 4 and gas density test instrument 1 and electric control valve 2, be wireless connections, wherein gas density testing instrument 1 is mainly used in testing gas density and concentration value is transferred to process control machine 4, process control machine 4 opens or closes by making electric control valve 2 make after the signal analysis of gas density test instrument 1 action of controlling conduit entrance accordingly.
When gas concentration is during lower than the economic value of current unit operation, first close the pipeline of concentration value minimum, through after a period of time, while measure finding gas concentration still lower than the economic value of current unit operation, close again remaining pipes, until the gas concentration of other units, higher than the economic value of current unit operation, is judged current gas concentration when process control machine 4 and, over after current unit operation economic value certain numerical value, is opened electric control valve 2.
