Problems solved by technology

[0002] The biggest problem in the current dry acetylene plant is that it is impossible to accurately control the feed ratio of raw calcium carbide and process water according to the gas generation and feed amount of raw calcium carbide
When the ratio of water to calcium carbide is too small, the calcium carbide reaction is incomplete, and the residual calcium carbide will bring safety hazards to subsequent processes and high product consumption; The phenomenon of wall sticking and channel blockage in the equipment affects the stable operation of the dry acetylene plant and also brings great difficulties to the comprehensive utilization of carbide slag

Embodiment Construction

[0019] according to figure 1 The process description of the process diagram of the precise control of the dry acetylene feed amount:

[0020] 1. Input the set value of acetylene gas flow and the actual gas production of this batch of calcium carbide into the microcomputer control system, and the microcomputer control system calculates the feeding amount of calcium carbide, and controls the calcium carbide feeding device to feed.

[0021] 2. The microcomputer control system calculates the set value of process water consumption through the gas generation and feeding volume of calcium carbide.

[0022] 3. The microcomputer control system calculates the standard mixed gas flow rate according to the pressure, temperature, flow rate and other parameters of the buffer tank and washing tower, and compares it with the set value of the acetylene gas flow rate to adjust the process water flow rate.

[0023] 4. The microcomputer control system calculates the acetylene flow value and the ...

Abstract

The invention relates to a method for controlling the feed amount in dry process acetylene production, which comprises the following steps: installing a gas flowmeter on a coarse acetylene gas outlet pipeline of a matched washing tower of a dry process acetylene device; interlocking the output flow of the gas flowmeter with a control system of a raw-material used water regulating valve; and automatically controlling the system to regulate vectors by a microcomputer so as to control the corresponding water distribution ratio, thereby realizing the accurate control of the feed proportioning.

Description

technical field [0001] The invention belongs to the technical field of chemical engineering, in particular to a method for controlling the amount of feed in dry acetylene production. Background technique [0002] The biggest problem existing in the dry acetylene plant at present is that it is impossible to accurately control the feeding ratio of raw calcium carbide and process water according to the gas generation and feeding amount of raw calcium carbide. When the ratio of water to calcium carbide is too small, the calcium carbide reaction is incomplete, and the residual calcium carbide will bring safety hazards to subsequent processes and high product consumption; The phenomenon of wall sticking and channel blocking in the equipment affects the stable operation of the dry acetylene plant, and also brings great difficulties to the comprehensive utilization of carbide slag. Contents of the invention [0003] The purpose of the present invention is to overcome the defects ...
