Description
Technical Field
The utility model relates to a bioreactor field, concretely relates to bioreactor gas sampling valve.
Background
At present, in the biological fermentation process, the biological fermentation process is often required to be known by analyzing the component content of the biogas, and the operation stability of the reactor and the like are judged. In the conventional gas sampling process, an on-line sensor is generally required to be installed for gas component detection, and the sampling amount is large, so that the cost and the benefit are high and low for a laboratory scale reactor, and the influence on the measurement result of the subsequent total gas volume is large due to the large gas sampling amount. In the conventional test, the latex hose is directly punctured by a syringe to perform gas sampling, but the non-special hose cannot avoid gas leakage after multiple punctures so as to influence the volume measurement result. Therefore, for small reactors on a laboratory scale, a dedicated gas valve is more necessary for off-line analysis and more convenient operation.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a bioreactor gas sampling valve is provided, is connecting line or airtight reactor and is used for making things convenient for the special sampling device of extraction gas sample for need often implement the occasion that gas sample sampling developed the composition analysis, can guarantee that the influence that gas volume measurement received is minimum, and the operation of getting the gas process is also very convenient, and the analysis gas composition that can be accurate.
The utility model provides a technical scheme that technical problem adopted is: the utility model provides a bioreactor gas sampling valve, includes the valve body, valve body upper portion is equipped with the sampling tube, and both sides are equipped with the connecting pipe respectively, the sampling tube top is equipped with the diaphragm to detain sealed fixed through screw cap or lock ring, be equipped with the through-hole in the middle of the screw cap, make a diaphragm part expose outside.
As a further improvement, the end part of the connecting pipe is provided with a concave-convex connecting buckle, and the connecting pipe is connected with an air outlet pipe of the reactor or a gas volume measuring unit or a gas adsorption unit.
Preferably, the valve body is a high borosilicate glass valve body.
Preferably, the diaphragm is made of silica gel materials and can be replaced.
The utility model discloses the sample valve can be installed in the reactor exit, passes through hose connection to the connecting pipe I of sample valve with the gas outlet of reactor, and connecting pipe II is connected to units such as gas volume measuring unit or gas adsorption. The sampling valve keeps certain slope when installing to avoid the vapor that produces in the biological fermentation process to condense and be detained in the sample valve body, thereby liquid water is extracted when also having avoided gaseous sample. In order to obtain representative gas, the bioreactor can be matched with a stirring system, and the gas in the bioreactor can be uniformly mixed by continuous stirring of the stirrer, and then the sample is taken.
The beneficial effects of the utility model are that set up special sample valve between connecting line or airtight reactor, the pipeline for expanding in the middle of the valve body forms certain cavity in order to save a certain amount of gas, supplies the sample extraction, can guarantee that the influence that gas volume measurement received is minimum, and the operation of gas taking process is also very convenient to the analysis gas composition that can be accurate. The concave-convex connecting buckle at the end part of the connecting pipe is used for connecting the hose and has a sealing effect.

Detailed Description
As shown in fig. 1 and 2, a gas sampling valve for a bioreactor comprises a borosilicate glass valve body 4, wherein an enlarged pipeline is arranged in the middle of the valve body to form a certain cavity for storing a certain amount of gas for sampling and extraction. 4 upper portions of borosilicate glass valve body are equipped with sampling tube 5, and both sides are equipped with connecting pipe I2 and connecting pipe II 3 that length is 2cm respectively, 5 tops of sampling tube are equipped with the diameter and are 8 cm's pellosil piece 6 to it is sealed fixed through screw cap 7, be equipped with through-hole 8 in the middle of the screw cap 7, make pellosil piece 6 some expose outside. The injectors are inserted from different positions in the circle part of the exposed silica gel membrane 6 to reduce the abrasion of the membrane during each sampling, and the silica gel membrane 6 can be replaced after multiple sampling, so that the tightness of a reactor and a pipeline system can be ensured, and the air leakage condition in the biological fermentation process is reduced. The end part of the connecting pipe is provided with a concave-convex connecting buckle 1, and the connecting pipe is connected with an air outlet pipe of the reactor or a gas volume measuring unit or a gas adsorption unit.
In order to obtain representative gas, the sampling injector can be inserted into the sampling pipe 5 and then the sampling injector is pressed back and forth to uniformly mix the sampled gas, and the sampling injector is quickly pulled out after the sampling gas is extracted, so that the gas leakage is avoided.
