Collection and recycling of VOC emissions from chemical pumping and storage trucks

In the petrochemical industry production process, storage tank residual material cleaning, and equipment maintenance, chemical substances containing chemicals pollute the environment. In order to avoid serious industrial safety fire problems, chemical pumping and storage tanks are used to clean sludge and remove pollution containing chemical components. substance. Generally, operators use pumped tank trucks made of chemical-resistant materials to remove various types of environmental pollution. However, when the vacuum pump with the pumping function of the pumped tank truck is running, a large amount of polluted exhaust gas is produced at the exhaust port, causing secondary environmental pollution. The vacuum pump is at high temperature and high speed. Operation and high-concentration VOC environments are prone to fire and industrial safety issues.

The exhaust port is fed into the chemical tank truck, and the oil and gas mixing inlet is designed to contain trace amounts of chemically detected organic matter, and the fuel is recycled and used under the combustion of the internal combustion engine. It is very effective to reduce the emission gas containing trace amounts and meet the requirements of energy saving, carbon reduction and environmental protection.

The internal combustion engine then uses the polluted exhaust gas to mix oil and air to support combustion. Since the recycled volatile organic gases (VOC) have different chemical compositions, and some substances will produce other polluting gases due to the internal combustion engine, equipment with a regenerative catalyst reaction function is installed at the exhaust port of the internal combustion engine to crack the chemical substances contained in the exhaust gas. is nitrogen. Improving the secondary environmental pollution caused by chemical pumping operations is very effective in preventing industrial safety fires and environmental pollution.

Function

When the green gate is started, the storage tank is sealed and exhausted at normal pressure. The storage tank with the green gate function uses a general pressure-resistant material container, which has high operational safety and can also save the cost of manufacturing the storage tank. The green gate is small in size, has a small space for vacuum storage and compression, and has a fast vacuum reaction speed. The power output can reduce energy consumption by more than 80%. The polluted exhaust gas emissions from the operation of the green gate system can be controlled by more than 95%.

Function

Environmental awareness of global warming is rising, and pollution prevention and control is urgent. When improving the pollution removal operation of the old traditional pumped tank trucks, the exhaust gas emitted by the vacuum extraction equipment of the pumped tank trucks carries a large amount of high-concentration VOC harmful gases and discharges them into the air, causing secondary environmental pollution. The old pump-storage tank truck follows the negative pressure function design of the century-old water and fertilizer vacuum tank truck. When vacuum pump-storage is used to remove chemical pollution, it emits high-concentration harmful VOC gases, causing environmental pollution problems.
The new single-axis air-to-air conveying design improves the VOC emission problem of traditional pumped storage trucks in the exhaust gas, significantly reduces pollution emissions, and effectively controls fire safety hazards and environmental health pollution prevention and control. The new single-axis air-to-air conveying and pumping storage equipment is simple to operate, durable in structure, and low in maintenance costs. The working environment of the pumped storage truck is exposed to chemical solvents and storage tank equipment in strong acid and alkali places. The shaft seal can prevent the generation of static sparks. It can withstand strong acid and alkali anti-corrosion materials 316L and Teflon materials. It has an explosion-proof power design function and uses air to drive the gate valve. Control, automatic function abnormal emission safety protection. The new single-axis air-to-air conveying design has imported upper and lower gravity flow conveying functions and is easy to control. When equipment malfunction occurs, emptying and discharging materials from top to bottom can quickly repair and maintain the equipment without affecting the functional operation of other equipment.
The general structure of a traditional vacuum pumping tank truck is based on the negative vacuum pressure generated by the vacuum pump when pumping the tank during pumping operation. The vacuum tank gate valve connects the pipeline to the contaminated area to extract any contaminated wastewater and chemical harmful substances. Pollution prevention and control work in the petroleum, chemical, and steel manufacturing industries includes cleaning of production process storage tanks, wastewater treatment systems and other pollution removal work. Especially in confined space and oxygen-deficient sealed high-risk places, it is very important to remove harmful substances from explosive chemical solvents. When vacuum pumping and storage pollutes the regional environment, the negative pressure reduces the risk of pollution caused by human body exposure when personnel clean up harmful substances on site. Vacuum pumping tank trucks are very suitable for environmental pollution cleanup projects.
The traditional vacuum storage tank truck has a simple structure, low manufacturing cost, safe operation, and easy maintenance. However, when the tank pumping and cleaning project contains VOC chemical substances, the pump of the tank pumping truck is in the process of extracting negative pressure from the storage tank for cleaning operations. , the chemical harmful substances in the storage tank of the pumped storage truck originally, and the VOC-containing gases were discharged in the exhaust gas of the vacuum pump. Some pollutants originally do not have VOC emission volatilization problems. In the negative pressure environment of vacuum pumping and storage operations, a large amount of harmful high-concentration gases are entrained in vacuum gas emissions, causing environmental emission pollution problems. It is very important to prevent and control industrial safety fire hazards and environmental sanitation pollution. .
The new type retains the old design of the vacuum storage tank, and uses the pumping storage tank and extraction vacuum equipment. It solves the problem of VOC volatilization and emission pollution caused by the negative pressure in the storage tank during the extraction operation of the old storage tank. The new type adopts a pump-storage design of a normal pressure storage tank. During the pumping and storage pollution operation, the pollutants in the storage tank are sealed at normal pressure and there is no concern about VOC volatilization and pollution. The new type of negative pressure isolation pumps and stores the pollution area, greatly reducing the volume by more than 20 times, and can reduce VOC pollution by more than 95%.
When the pumped storage vehicle is in standby operation, the single-axis switching design function is designed to avoid any VOC and odor emission problems caused by the environment. The new single-axis air-to-air conveying pumping and storage equipment reduces the power output of the vacuum pumping equipment. Due to the reduced pumping and storage volume, the vacuum pumping and storage power output effectively reduces energy consumption by more than 80% during pollution extraction operations under the same conditions. The new type of extraction operation is designed for normal pressure. The structural strength of the storage tank can reduce the required standards and greatly improve the safety of use in the storage tank. The design of the normal pressure storage tank simplifies the structural manufacturing and can save a lot of costs.
The green gate device can improve the problem that traditional vacuum pumping tank trucks easily produce large amounts of VOC harmful gases during pollution removal operations. The green gate system can be installed on the existing pumped storage tank vehicle. The green gate system and the storage tank are separate and independent, and the valve is switched in the air between the two. The storage tank is designed at normal pressure, and volatile VOC gas will not be discharged out of the storage tank.
