Abstract
The utility model relates to a buffer protection device for hydrogen gas feeding and belongs to the field of chemical industrial production protection devices. The buffer protection device for hydrogen gas feeding comprises a buffer tank, a flow meter, an electric adjustment valve, an electric ball valve, a disconnecting valve A, a disconnecting valve B and a disconnecting valve C. The upper portion of the buffer tank is provided with the flow meter, the electric adjustment valve and the electric ball valve are arranged sequentially on one side of the flow meter, and the buffer tank is connected with the electric adjustment valve and the electric ball valve through a pipeline and the flow meter. The protection device is simple in structure, capable of performing secondary adjustment on gas passing through the buffer tank and the flow meter through the electric adjustment valve and the electric ball valve which are arranged on the pipeline, ensuring that hydrogen gas enters a reaction kettle in a required flow and required pressure to finish synthesis production technology, resolving the problem that yield coefficient and purity of products are influenced once error occurs in an existing protection device, ensuring the yield coefficient and the purity of the products and ensuring that gas flows smoothly when the electric adjustment valve is maintained or replaced by means of a parallel-connection pipe so as to avoid production being delayed by gas disconnection.
Description
Technical field
The utility model relates to a kind of hydrogen air inlet buffer protection device, belongs to chemical production equipment protective gear field.
Background technique
In chemical product are produced, having many production technologies all will use hydrogen, like chemical product dissident glycol, is to be that raw material is synthetic through catalytic hydrogenation with the diacetone alcohol; This technology is simple; Raw material is easy to get, and the product yield of gained reaches more than 90%, and product purity is 99%; Being prone to realize industrialized production, is domestic and international at present main synthesis and production process.The hydrogen air inlet of existing equipment all is to be main protective gear with knock out drum, and gas gets into reaction kettle through flowmeter and accomplishes synthesis and production process, and in a single day it go wrong, and will influence the yield and the purity of product.
Summary of the invention
The purpose of the utility model is: a kind of simple in structure, stable performance is provided, in a single day goes wrong to solve existing protective gear, will influence the hydrogen air inlet buffer protection device of product yield and purity problem.
The utility model is to realize above-mentioned purpose through following technological scheme:
A kind of hydrogen air inlet buffer protection device; It is made up of knock out drum, flowmeter, electric control valve, electric ball valve and stop valve A, stop valve B, shutoff valve C; It is characterized in that: the knock out drum top is provided with flowmeter; Flowmeter one side is disposed with electric control valve and electric ball valve, and knock out drum is connected with electric ball valve with electric control valve through flowmeter by pipeline; Be respectively arranged with stop valve A and stop valve B on the said electric control valve pipelines on two sides, pipeline between flowmeter and the stop valve A and stop valve B are communicated with through parallel transistor with pipeline between the electric ball valve, and parallel transistor is provided with shutoff valve C.
The beneficial effect of the utility model is:
This hydrogen air inlet buffer protection device is simple in structure; Through electric control valve on the pipeline and electric ball valve; Can carry out secondary to the gas of flow through knock out drum and flowmeter and regulate, guarantee that hydrogen gas flow and pressure on demand gets into reaction kettle completion synthesis and production process, to guarantee the yield and the purity of product; This hydrogen air inlet buffer protection device can be guaranteed the unimpeded of gas through parallel transistor when electric control valve maintenance is changed, thereby avoiding stopping the supple of gas or steam delays production.
Description of drawings:
Accompanying drawing is the structural representation of hydrogen buffering protective gear.
Among the figure: 1, knock out drum, 2, flowmeter, 3, pipeline, 4, electric control valve, 5, electric ball valve, 6, stop valve A, 7, stop valve B, 8, shutoff valve C, 9, parallel transistor.
Embodiment:
This hydrogen air inlet buffer protection device is made up of knock out drum 1, flowmeter 2, electric control valve 4, electric ball valve 5 and stop valve A6, stop valve B7, shutoff valve C 8; Knock out drum 1 top is provided with flowmeter 2, and flowmeter 2 one sides are disposed with electric control valve 4 and electric ball valve 5.Knock out drum 1 is connected with electric ball valve 5 with electric control valve 4 through flowmeter 2 by pipeline 3.
Be respectively arranged with stop valve A6 and stop valve B7 on electric control valve 4 pipelines on two sides 3, pipeline 3 between flowmeter 2 and the stop valve A6 and stop valve B7 are communicated with through parallel transistor 9 with pipeline 3 between the electric ball valve 5, and parallel transistor 9 is provided with shutoff valve C 8.
During this hydrogen air inlet buffer protection device work, hydrogen source gas gets into this protective gear through knock out drum 1, and accomplishes synthesis and production process through the electric ball valve 5 final reaction kettles that get into manufacturing mechanism of this protective gear.This protective gear can carry out secondary to the gas of flow through knock out drum 1 and flowmeter 2 and regulate through electric control valve on the pipeline 34 and electric ball valve 5, gets into reaction kettle to guarantee hydrogen gas flow and pressure on demand, to guarantee the yield and the purity of product.This protective gear can be guaranteed the unimpeded of gas through parallel transistor 9 when electric control valve 4 maintenance is changed, thereby avoiding stopping the supple of gas or steam delays production.
