Automatic air pressure control safety device

Abstract

The invention discloses an automatic air pressure control safety device, and belongs to the field of waste tire pyrolysis. The device comprises a box body. An air inlet pipe and a liquid level pipe are arranged on the left side face of the box body, and a liquid injection opening is formed in the upper left portion of the box body. An air collecting box is arranged in the box body, one end of the air inlet pipe penetrates through the left side of the box body to enter the air collecting box, the air collecting box and a liquid-air separation box are communicated through a rising air channel in the middle of the interior of the box body, an air outlet pipe is arranged on the upper portion of the liquid-air separation box, a back-flow pipe is arranged on the lower portion of the liquid-air separation box, the lower end of the back-flow pipe is arranged at the bottom of the box body, and a combustion chamber conveying pipe is arranged on the left side of the box body to prevent harmful waste gas from being discharged into the atmosphere to pollute the atmosphere. By means of the relation between the liquid level and the pressure intensity, the air pressure in the air inlet pipeline is controlled according to the liquid level in the box body, and the problems that pressure control of a manual valve is not accurate and not timely, and the valve is prone to gas leakage and blockage due to abrasion are solved. When the air pressure in the system is too high, the manual valve cannot react in time, and major potential safety hazards of pipeline breakage, air leakage, fire explosion, reaction kettle explosion and waste gas collection device explosion are caused.

Description

Technical field[0001]The present invention relates to the field of high temperature lysis of waste tires, and is specifically an automatic control of the air pressure safety device.Background technique[0002]The waste tire high temperature lysis system produces a large amount of flammable gas when operating, and the gas is delivered to the reaction kettle combustion heating in the system through the pipeline, and the excess combustion gas is discharged into the exhaust gas collection device. When the waste tire is operating at a high temperature lysis system, the reaction kettle in the system requires rated and stable pressure, and the flammable gas has a large amount of impurities, and there is a very strong corrosive, and it is easy to block the corrosion spring safety valve. Therefore, it is currently an ingenious manual control of the ball valve to adjust the reactor pressure and pipe pressure. The manual adjustment valve is not accurate. It is not timely, the valve wear is so ea...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an automatic control air pressure safety device to solve the problem that when waste tires are pyrolyzed at high temperature, the reaction kettle and combustible gas combustion in the system need rated and stable pressure, and the control pipeline in the system needs to be rated and stable. The air pressure is controlled by a manual valve. When it is necessary to adjust the pressure, the size of the valve is manually adjusted. The manual control valve has pressure control that is not accurate and timely, and the valve is worn and easy to leak.
