Abstract
The invention discloses a multi-unit pump parallel feed system which comprises a raw material tank (1), a raw material tank outlet tee-joint valve (2), a main liquid release valve (3) and at least two material inlet units (4), wherein the upper end of the raw material tank (1) is provided with an inert gas supply opening (5), a material adding hole (6) and a pressure gauge (7); the lower end of the raw material tank (1) is connected with the end 1 of the raw material tank outlet tee-joint valve (2) through a pipeline; the end 3 of the raw material tank outlet tee-joint valve (2) is connected with the end 1 of the main liquid release valve (3) through a main liquid transmitting pipeline (8); each material inlet unit (4) is composed of a material inlet pump (10) and a pump inlet tee-joint valve (9). The multi-unit pump parallel feed system has the advantages of simple structure, reasonable design, compact in layout, good in parallelity and the like and is convenient to use and easy to manufacture.
Description
Technical field:
The present invention is a kind of polynary pump parallel feed system, belongs to technical field of chemical.
Background technology:
High throughput test device, as the Important Platform of catalyst screening and technical study, has become the study hotspot in the fields such as domestic and international oil, chemical industry, medicine, environment and material at present.General catalysis is all by gas-liquid-solid phase reaction, such as: Fischer-Tropsch synthesis, vegetable oil hydrogenation reaction, the reaction of alkane autothermal cracking etc., and the conveying of liquid material is controlled by feed pump.So how to guarantee that in high throughput test device the compactness stable, space layout of liquid charging all seems particularly important.
Summary of the invention:
The object of the present invention is to provide a kind of reasonable in design, collimation good, compact in design, be applicable to the polynary pump parallel feed system of high-throughput device.
A kind of polynary pump parallel feed system, comprise head tank (1), head tank outlet triple valve (2), total bleeder valve (3) and at least two feed unit (4), it is characterized in that: there is inert gas gas supplementing opening (5) described head tank (1) upper end, charge door (6) and Pressure gauge (7), head tank (1) lower end is connected with 1 end of head tank outlet triple valve (2) by pipeline, 3 ends of described head tank outlet triple valve (2) are connected with 1 end of total bleeder valve (3) by total transfer line (8), described feed unit (4) is comprised of feed pump (10) and pump intake triple valve (9).
3 ends of described pump intake triple valve (9) are connected with the entrance of feed pump (10), 1 end of pump intake triple valve (9) is connected with total transfer line (8) by pipeline, 2 ends of pump intake triple valve (9) are directly emptying, for tapping.
2 ends of described head tank outlet triple valve (2) are directly emptying, for tapping.
2 ends of described total bleeder valve (3) are directly emptying, for tapping.
A kind of polynary pump parallel feed system tool provided by the invention has the following advantages: reasonable in design, compact in design, all raw materials all come from same head tank (1), guaranteed the consistent of material source, and head tank (1) upper end is provided with inert gas gas supplementing opening (5) and Pressure gauge (7), seal to the certain pressure of head tank (1), by total liquid-transport pipe-line (8), carry out convey materials simultaneously, conveniently by pipeline, be connected with each feed unit (4), charging separately between each feed unit (4), also charging simultaneously, is independent of each other.
