Abstract

The invention provides a trapping device for tetrachloroisophthalonitrile synthesis gas, and a use method and application of the trapping device. The trapping device comprises a trapping device body and a top sealing head arranged above the trapping device body, wherein the trapping device body comprises at least two sets of trapping assemblies which are arranged at intervals and are independent of each other in the length direction of the trapping device body; each set of trapping assembly comprises at least one trapping shell arranged side by side in the width direction of the trapping device body, a longitudinal baffling baffle is arranged in each trapping shell, the baffling baffles are parallel to the width direction of the trapping device body, and the baffling baffles divide the interior of each trapping shell into an outward trapping chamber and a return trapping chamber with communicating bottoms; a jacket is arranged on the outer side of the trapping device body; the trappingshells are arranged in the jacket at intervals in a matrix mode, and a cooling medium is introduced into the jacket; and the top sealing head is used for communicating the tops of the two adjacent trapping assemblies, longitudinal partition plates opposite to the baffling baffles are arranged in the sealing head, and a gas inlet and a gas outlet are formed in the two sides of the short edge of the top sealing head respectively.

Description

technical field [0001] The invention belongs to the technical field of desublimation capture, and relates to a capture device, its use method and application, in particular to a capture device for tetrachloroisophthalonitrile synthesis gas, its use method and application. Background technique [0002] As a high-efficiency, low-toxicity, broad-spectrum protective fungicide, tetrachloroisophthalonitrile is a kind of contact killer, which mainly prevents and treats various fungal diseases. Since the 1960s, tetrachloroisophthalonitrile It has been widely used as a fungicide, mainly used for the prevention and control of rust, anthracnose, powdery mildew and downy mildew on fruit trees and vegetables, and to prevent plants from being damaged by fungi. Tetrachloroisophthalonitrile is also used abroad for the sterilization of golf courses, lawns, and ornamental plants, as well as for the antiseptic treatment of certain trees and paintings. [0003] At present, the most important m...
