Embodiment 2

[0024] The working process of the reactor described in Example 2 is: the gas to be purified enters the first filter chamber after entering the air inlet at the bottom, and goes up through the air flow channel on the peripheral wall of the first filter chamber to the point between the top of the first filter chamber and the bottom of the second filter chamber. After entering the conical airflow channel between them, it enters the high-efficiency composite biological enzyme catalytic layer of the second filter chamber, and finally discharges from the top air outlet. Its advantages and effects are reflected in the fact that after the gas to be purified enters the first filter chamber, it needs to go up from the air flow channel on the surrounding wall and then pass through the conical air flow channel. The air flow channel goes up, and the filtered gas can fully contact with the complex biological enzyme catalytic layer of the university, and the dust filtering effect is good.

Abstract

The invention relates to the technical field of a high-efficiency gas purification bioreactor based on a complex enzyme immobilization technology and a purification method thereof. The high-efficiency gas purification bioreactor comprises a vertical glass fiber reinforced plastic tank body, wherein the lower part of the tank body is provided with a gas inlet, a high-efficiency complex enzyme catalysis filling layer is arranged on an upper cavity, and the top of the tank body is connected with a gas outlet and provided with a safe valve. The bioreactor and the method can use a specific complex enzyme catalytic degradation function to process gas which is difficult to process by the prior pollution treatment art, has the enzyme catalytic degradation function, removes or converts useless gas or harmful gas, remains or obtains useful gas and has low processing cost, high efficiency and convenient use.

Description

technical field [0001] The patent of the present invention relates to the technical field of high-efficiency bioreactor for gas purification based on composite enzyme immobilization technology and its purification method, especially through the special-effect bio-enzyme catalytic degradation function to process the gas that is difficult to handle in some current pollution control technologies. Purified high-efficiency bioreactors. Specifically, it refers to a gas purification high-efficiency bioreactor with a bio-enzyme-catalyzed degradation function and a composite bio-enzyme immobilization technology that can make gas purification more efficient and thoroughly purify the gas. Suitable for alkanes, aldehydes, alcohols, ketones, carboxylic acids, esters, ethers, triphenyls, olefins, polycyclic aromatic hydrocarbons, VOCs, hydrogen sulfide, ammonia, hydrogen disulfide, sulfur dioxide, Purification treatment of various common organic waste gases such as carbon disulfide and ino...
