Abstract

The invention discloses a fuel gas odorization device. The fuel gas odorization device is characterized by comprising an odorant injection nozzle, an injection switch, a check valve, an odorization valve, a pressure gauge, a pressure valve, a one-way valve A, a metering pump, an explosion-proof switch, an explosion-proof connecting box, a one-way valve B, a stop valve, a filter, an overhead valve, a liquidometer, a bottom valve, a return valve, a breather, a liquid charging valve, a liquid storage tank, a blowdown valve and a controller. According to the fuel gas odorization device, odorization is achieved mainly by pumping odorants (THT) out of the liquid storage tank and pumping the odorants (THT) in a fuel gas transmission and distribution main pipe through the micro-type diaphragm metering pump. The fuel gas odorization device has the function of manual and full-automatic switchover, and is flexible in odorization mode. To achieve the aim of accurate odorization, a flow detection device and a signal collection and transmission device are arranged in the transmission and distribution main pipe, and signals are fed back to a computer. The computer controls the odorant quantity of the metering pump according to the set odorant quantity needed by fuel gas flow per cubic meter, the odorization effect of natural gas is guaranteed, and user using safety is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of gas odorization, in particular to a gas odorization device. Background technique [0002] If there is a gas leakage during the gas supply process, on the one hand, it is easy to form an explosive mixture and cause an explosion; on the other hand, it is easy to cause poisoning and death, causing casualties and property losses. In order to detect gas leakage in time and take effective measures to control gas leakage in time, it is usually necessary to install an alarm during the supply process of town gas to warn of gas leakage according to the odor concentration in the air. Usually the minimum amount of odorant in the gas should meet the following provisions in the "Code for Design of Town Gas": (1) When non-toxic gas leaks into the air and reaches 20% of the lower explosion limit, it should be detected in time; (2) Toxic When the gas leaks into the air and reaches the harmful concentration allowed to the...
